feat(v0.6.5): execution-grounded skill-utility report (adam-skill-utility)

Ranks skills by good:bad outcome co-occurrence (Wilson LB + lift vs baseline) over the journal's active_skills payloads — the SkillsInjector (arXiv 2605.29794) execution-grounded utility signal Δ(s), computed from data already collected, no training. - reuses adam-score NEGATIVE_SIGNAL_TYPES + entrySeverity (single source of truth) - registered in install.sh helper-script copy loop - /reflect pre-step surfaces worst below-baseline skills to the USER as advisory (co-occurrence != causation; not fed to the analyst's proposal machinery) - Test 119 added; full suite 141/141 green
fix(v0.6.4): rollback removes the proposal's ab-tracking entry

 # claude-adam

-Self-improvement layer for [Claude Code](https://claude.com/claude-code) that observes friction signals during your sessions and proposes targeted improvements (new skills, memory entries, agent edits) which you can review and apply.
+**A self-improvement layer for [Claude Code](https://claude.com/claude-code).**

-## What's new
+Watches the friction in your coding sessions, clusters the signals via an LLM analyst, and proposes targeted improvements — new skills, memory entries, agent edits — that you review and apply.

- **v0.3.3** — analyst observability, A/B measurement, journal hygiene. Storage/window/exclusion split: ISO-week journal rotation with safety fuse (replaces size-based, fixes silent under-counting); per-signal sliding windows via new `adam-window.mjs` (`dead_end` 7d, `correction` 30d, reinforcement signals 60d). Error fingerprint normalization — `ECONNREFUSED` and `"Connection refused"` cluster identically. Correction corpus expanded (`wait`, `hold on`, `try again`, `different approach`); weak tokens (`no`, `actually`, `wait`) require negation co-occurrence within 8 tokens to fire — kills the `"actually, I think..."` false positive. Mandatory clustering trace + new `adam-explain.mjs --mode summary|full|json`. New `nudge` proposal type (single-session auto-apply, low blast) for repeated `dead_end`. Per-(skill, fingerprint) cooldown via `adam-cooldown.mjs` (replaces coarse per-skill gate). `task_completed` scoring: urgency dampener + reinforcement candidates. A/B effectiveness measurement on auto-applied edits (`adam-ab-measure.mjs`, 7d pre/post window). Upgrade UX overhaul: `adam-upgrade.mjs --list/--diff/--accept` + SessionStart pending-merge warning. Shared helper module `adam-utils.mjs` deduplicates journal-reading and frontmatter parsing across scripts. 87 tests (up from 30).
- **v0.3.2** — `task_completed` signal: post-task skill capture for downstream reinforcement scoring (consumed in v0.3.3).
- **v0.3.1** — code review pass: bug fixes (`errorFingerprint` no longer false-positives on `is_error: false`, archive script handles same-millisecond duplicates correctly, `tool_window` now clears on session change, nudge filters proposal filenames by pattern), prose conciseness cuts, hardened `install.sh` with curl one-liner + settings.json merge, `adam-uninstall.sh`, isolated test harness (no longer pollutes live `~/.claude/adam/` state).
- **v0.3.0** — causal diagnosis: every proposal carries a `# Diagnosis` block (Trigger/Action/Mismatch/Outcome with verbatim transcript quote) before drafting, plus optional `contradiction_flag` heuristic that vetoes auto-apply on obviously-conflicting `skill_edit` additions.
- **v0.2.1** — win signals (`correction_free_streak`, `clean_recovery`) feed `skill_edit` auto-apply under a strict gate (≤30 LOC, ≤2× byte cap, 7d cooldown, 30d blacklist on rejection).
- **v0.2.0** — actioned-entry archival via `adam-archive.mjs`; `cursor` field deprecated.

-## What it does
+</div>

-A lightweight Node.js hook (`adam-observe.mjs`) runs on `UserPromptSubmit`, `PreToolUse`, and `PostToolUse` events. It detects:
+---

-| Signal | Trigger |
-|---|---|
-| `correction` | User prompt contains "no", "stop", "wrong", "actually", etc. after a tool call |
-| `retry_loop` | Same tool + same args called 3× in a 10-event window |
-| `weak_agent` | Same subagent dispatched 2× in last 5 tool calls |
-| `tool_error_loop` | Same error fingerprint appears 3× in a 5-event ring |
-| `dead_end` | 8 PostToolUse events without a UserPromptSubmit between them |
-| `edit_churn` | Same file edited 4× in a window |
-| `build_loop` | 2× build/test/compile commands fail in same session |
-| `subagent_dispatch_pattern` | Same subagent dispatched ≥3× cumulatively |
-| `correction_free_streak` | 5 clean UserPromptSubmits in a row (no correction phrase) — feeds `skill_edit` reinforcement |
-| `clean_recovery` | 3 clean PostToolUse events after a struggle signal — feeds `skill_edit` reinforcement |
+## The story behind Adam
+
+Adam is my newborn son.
+
+Watching him over the last few months — the way he observes the world, tries something, watches what happens, adjusts, and tries again — I realised that the most powerful learning loop in nature is also one of the simplest. No grand theory. No instruction manual. Just relentless feedback and pattern recognition, applied to every waking moment.
+
+LLMs can learn the same way. Give them a hook into the real friction of your work — the corrections, the dead-ends, the moments you say *"no, try again"* — and let them propose improvements grounded in **what actually happened**. Not what they assume might help. What you actually struggled with.
+
+**claude-adam** is that loop, wired into Claude Code. It's named after Adam because the methodology is his.
+
+---
+
+## Highlights
+
+- 🔍 **Zero LLM cost at observation time.** Deterministic regex + counter detection in a Node hook. The analyst only runs when you invoke `/reflect`.
+- 📡 **11 signal types.** Friction (`correction`, `tool_error_loop`, `dead_end`, `edit_churn`, …) + reinforcement (`task_completed`, `correction_free_streak`, `clean_recovery`) + meta.
+- 🛡️ **Tight auto-apply gates.** Confidence ≥ 4, cross-session evidence, contradiction veto, per-(skill, fingerprint) cooldown. Most things queue for your manual review.
+- 📊 **A/B effectiveness measurement.** Every auto-applied edit gets a 7-day pre/post signal-count delta. If a proposed fix made things worse, the next `/reflect` says so.
+- ⏳ **Per-signal sliding windows.** Stale friction doesn't accumulate forever. `dead_end` 7d, `correction` 30d, reinforcement signals 60d.
+- 🔬 **Observable.** Every clustering decision (passed / threshold-blocked / window-filtered / contradiction-vetoed) emits a trace. `/reflect --explain` shows it.
+- 📦 **Pure Node.** Zero npm dependencies. Runs on macOS and Linux (Alpine smoke-tested).
+
+## Quick start
+
+```sh
+curl -fsSL https://raw.githubusercontent.com/lukaszraczylo/claude-adam/main/install.sh | bash
+```
+
+The installer copies files into `~/.claude/`, offers to merge ADAM's hook entries into `~/.claude/settings.json` (with a diff preview and `[y/N]` confirm), and preserves any local edits via `.adam-new` sidecar files. Pass `--yes` to skip prompts, `--dry-run` to preview.
+
+Then:
+
+```sh
+bash ~/.claude/adam/tests/run-tests.sh   # expect: 140 passed, 0 failed
+# … start a fresh Claude Code session …
+/reflect                                  # walks the proposal queue
+/reflect --explain                        # also shows the analyst's clustering trace
+```
+
+Pin a release for reproducibility:
+
+```sh
+curl -fsSL https://raw.githubusercontent.com/lukaszraczylo/claude-adam/v0.6.3/install.sh \
+  | VERSION=v0.6.3 bash
+```
+
+### Staying up to date
+
+`install.sh` records the installed release in `~/.claude/adam/.version`. The
+SessionStart hook (`adam-nudge.mjs`) then checks the latest GitHub release **at
+most once a day** (cached in `~/.claude/adam/.update-check.json`, network call
+hard-capped at 1.5 s, fully best-effort — it never blocks or slows session
+start). When a newer release exists it prints a one-line, **notify-only** prompt:
+
+```
+[adam] update available: v0.6.3 → v0.6.4. Apply: curl -fsSL …/install.sh | bash
+       (re-runs install.sh — resets ADAM's own /reflect-applied skill edits; apply when you're ready)
+```
+
+It is deliberately **not** auto-applied: re-running `install.sh` overwrites
+ADAM's own `/reflect`-applied skill edits, so you decide when to take an update.
+Disable the check entirely with `ADAM_NO_UPDATE_CHECK=1` in your environment.

+
+The observation layer is a ~600-line Node hook. Pure regex, counters, ring buffers — no LLM in the hot path. Signals append one JSONL line per detection to `~/.claude/adam/journal.jsonl`.
+
+The analysis layer is an LLM subagent invoked by `/reflect`. Before the analyst runs, three deterministic pre-processors filter and enrich the journal: `adam-window.mjs` drops stale entries per per-signal age, `adam-score.mjs` computes per-session urgency dampeners + reinforcement candidates, and `adam-ab-measure.mjs` checks whether previously auto-applied edits actually reduced their originating signal.
+
+The analyst clusters signals, scores them against a deterministic rubric (see below), and emits proposal markdown files to `~/.claude/adam/proposals/`. Each proposal carries a `# Diagnosis` block (Trigger / Action / Mismatch / Outcome with a verbatim transcript quote), a `# Success criterion`, and the source journal-entry timestamps it clustered.
+
+Auto-apply runs only for low-blast types (memory entries, new skills, ephemeral nudges, reinforcement logs) backed by cross-session evidence. Everything else queues for your manual approve / reject / edit walk.
+
+## Signals
+
+| Signal | Trigger | Window* |
+|---|---|---|
+| `correction` | Strong tokens (`stop`, `wrong`, `undo`, …) OR weak tokens (`no`, `actually`, `wait`) with negation/contrast nearby | 30d |
+| `retry_loop` | Same tool + same args called 3× in a 10-event window | 14d |
+| `weak_agent` | Same subagent dispatched 2× in last 5 tool calls | 30d |
+| `tool_error_loop` | Same error fingerprint 3× in a 5-event ring (fingerprints normalised — `ECONNREFUSED` and `"Connection refused"` cluster) | 30d |
+| `dead_end` | 8 PostToolUse events without a UserPromptSubmit between them | 7d |
+| `edit_churn` | Same file edited 4× in a window | 14d |
+| `file_reread` | Same file Read ≥3× in the 10-event window, ignoring offset/limit (catches re-reads that escape `retry_loop`'s arg-hash dedup) | 14d |
+| `build_loop` | 2× build/test/compile commands fail in same session | 30d |
+| `subagent_dispatch_pattern` | Same subagent dispatched ≥ 3× cumulatively | 30d |
+| `correction_free_streak` | 5 clean UserPromptSubmits in a row — reinforcement input | 60d |
+| `clean_recovery` | 3 clean PostToolUse events after a struggle signal — reinforcement input | 60d |
+| `task_completed` | 5 tools / 3 kinds / 0 corrections — fed into the urgency dampener + reinforcement candidates | 60d |
+
+\* Per-signal sliding window for `/reflect` analysis. See `SIGNAL_WINDOWS_DAYS` in `adam/scripts/adam-window.mjs`.

 Detection is local, regex-based, zero LLM cost. Signals append to `~/.claude/adam/journal.jsonl`.

-When you run `/reflect`, the `adam` subagent reads the journal, clusters signals, scores them against a deterministic rubric, and emits proposal files to `~/.claude/adam/proposals/`. Auto-applied proposals only ship for low-blast types (memory, new skills) backed by cross-session evidence; everything else queues for your manual approve/reject/edit walk.
+## Auto-apply rubric

-## Why
+```
+Sum:
+2  Signal repeated ≥ 3× across ≥ 2 sessions (within signal's window)
+2  Struggle signal appearing ≥ 1× within a single session (does not stack)
+2  Transcript contains positive endorsement near related action
+1  Multi-axis cluster (≥ 2 distinct struggle types in same session)
+-1  Type-bias penalty (≥ 3 rejections, applied:rejected < 1:2)
+1  Blast radius low (memory or new isolated skill)
+ 0  Blast radius medium (new agent, new hook, edit existing skill)
+-1  Blast radius high (CLAUDE.md, settings hooks, edit agent, deletion)
+1  Surgical (one file, ≤ 50 LOC for non-skill_new; ≤ 80 LOC for skill_new)
+-3  Touches deny-list (settings.json hooks/permissions, CLAUDE.md, deletions)
+```

-LLM coding sessions reveal repeated friction the moment you stop and look. ADAM looks so you don't have to.
+Modifiers applied at scoring time:
+
+- × `dampener` from `adam-score.mjs` (0.5 / 0.75 / 1.0 based on session's `task_completed` count) — sessions that net-succeeded score lower urgency.
+
+`auto_apply_eligible` requires **all** of:
+
+- `confidence ≥ 4`
+- `blast_radius == low`
+- `type ∈ {memory, skill_new, nudge, reinforcement}` (or `skill_edit` via the win-driven gate)
+- `cross_session_evidence == true` (except `nudge`, which is single-session by design)
+- `adam-cooldown.mjs` returns `cool` for `(target_skill, proposal_fingerprint)`
+- `contradiction_flag` unset
+
+`skill_edit` additionally requires:
+
+- Win-signal evidence (`correction_free_streak` / `clean_recovery` cites target skill)
+- Diff is append-only, ≤ 30 LOC, resulting size ≤ 2× original
+- No auto-edit to same target in past 7 days (per-fingerprint cooldown)
+- No rejection-blacklist on target in past 30 days
+- `# Diagnosis` section present + structurally valid
+
+Everything else queues.
+
+## Lifecycle: from signal to permanent improvement
+
+Every proposal records the journal entry timestamps that fed its cluster (`source_entries` in frontmatter). When you apply or reject a proposal, the skill calls `adam-archive.mjs` which moves matching entries from `journal.jsonl` to `journal/actioned-<id>.jsonl`. The result:
+
+- `journal.jsonl` stays bounded by **active** observations only.
+- The next `/reflect` reads `applied/` + `rejected/` frontmatter, builds an excluded-timestamps set, and skips any leftover journal entries that were already actioned.
+- Rule changes (e.g. lowering a threshold) immediately re-evaluate the remaining active observations — no manual cursor rewind needed.
+
+Auto-applied proposals additionally append to `~/.claude/adam/ab-tracking.jsonl`. The next time `/reflect` runs (and 7+ days have passed), `adam-ab-measure.mjs` computes a pre/post delta of the originating signal count. Status: `improved` / `neutral` / `regressed` / `no_baseline` / `pending`. Regressions surface at the top of the analyst's output so a bad fix doesn't quietly persist.
+
+## Inspecting the analyst's reasoning
+
+Every `/reflect` run also writes the analyst's clustering trace to `~/.claude/adam/last-trace.txt`. The trace records, per cluster: signal type, occurrence count, sessions, which gates passed or failed, and whether the cluster produced a proposal or was skipped (with reason: `threshold` / `cross_session` / `window` / `contradiction` / `other`).
+
+```sh
+node ~/.claude/adam/scripts/adam-explain.mjs --mode summary   # SUMMARY + per-decision counts
+node ~/.claude/adam/scripts/adam-explain.mjs --mode full      # verbatim trace + rejection histogram
+node ~/.claude/adam/scripts/adam-explain.mjs --mode json      # machine-readable
+```
+
+Or pass `--explain` to `/reflect` to render the full trace inline.
+
+## What it will not do
+
+- 🚫 No background LLM spend. The analyst runs only when you invoke `/reflect`.
+- 🚫 No retroactive transcript mining beyond the journal.
+- 🚫 No hard `rm` of any artifact. Deletions are soft (`mv` to `trash/<ts>/`).
+- 🚫 No autonomous edits to `CLAUDE.md`, agents, hooks, or `settings.json` — these always queue for review regardless of confidence.
+- 🚫 No proposal that matches a previously-rejected idea (≥ 2 token overlap with rejection's `# Why`).
+- 🚫 No invented trigger phrases for new skills — every trigger comes from observed user input.

-## Install
+## What's new

-### One-liner (recommended)
-
-```sh
-curl -fsSL https://raw.githubusercontent.com/lukaszraczylo/claude-adam/main/install.sh | bash
-```
-
-Pin a release for reproducibility:
-
-```sh
-curl -fsSL https://raw.githubusercontent.com/lukaszraczylo/claude-adam/v0.3.1/install.sh \
-  | VERSION=v0.3.1 bash
-```
-
-The installer clones the repo to `/tmp`, copies files into `~/.claude/`, and offers to merge ADAM's hook entries into your `~/.claude/settings.json` (with a diff preview and `[y/N]` confirmation — your existing hooks are preserved). Pass `--yes` to skip the prompt; `--dry-run` to preview without writing.
-
-Requires `git`, `curl`, `jq`, and `node` 18+.
-
-### From a clone
-
-```sh
-git clone https://github.com/lukaszraczylo/claude-adam
-cd claude-adam
-./install.sh
-```
-
-### Upgrade-safe
-
-These files are **never overwritten** if they already exist:
-
- `~/.claude/adam/journal.jsonl` — your observation log
- `~/.claude/adam/state.json` — session counters
- `~/.claude/adam/usage.json` — invocation tallies
-
-If you've locally edited any installed file (e.g. `agents/adam.md`), the installer writes the new version to `<file>.adam-new` and warns you instead of clobbering.
-
-After install: run `bash ~/.claude/adam/tests/run-tests.sh` to verify (expect `27 passed, 0 failed`), start a fresh Claude Code session, then run `/reflect`.
+- **v0.6.4** — rollback now keeps its promise. `adam-rollback.mjs`'s docstring always claimed it "removes the ab-tracking entry (so it doesn't re-trigger)," but `executeRollback()` never did — so a rolled-back proposal kept flagging as `regressed` on every subsequent `/reflect`, triggering endless `not_found` rollback attempts. It now deletes the matching `ab-tracking.jsonl` row by `proposal_id` (preserving unrelated rows). Surfaced by running ADAM's own loop twice. 140 tests (up from 138).
+- **v0.6.3** — release-update notifier. `install.sh` now writes a `~/.claude/adam/.version` marker; `adam-nudge.mjs` (SessionStart) compares it against the latest GitHub release at most once/day (cached, 1.5 s network cap, best-effort — never blocks) and prints a **notify-only** one-line update prompt. Deliberately not auto-applied: re-running the installer resets ADAM's own `/reflect`-applied skill edits, so you choose when to update. Opt out with `ADAM_NO_UPDATE_CHECK=1`. See "Staying up to date". 138 tests (up from 134).
+- **v0.6.2** — two fixes surfaced by running ADAM's loop on a large real journal. **(1) A/B volume normalization** (`adam-ab-measure.mjs`): regressions are now measured on the signal's *share* of total activity (rate = count / window-total), not raw count — so a generally busier journal after an apply no longer masquerades as a regression. Falls back to raw delta when the signal is the only activity in the window (preserves prior behavior + tests); output adds `raw_delta_pct`, `pre_total`, `post_total`, `normalized` for transparency. **(2) Memory frontmatter schema** (`agents/adam.md`, `SKILL.md`): the drafting protocol now emits the live auto-memory shape — `name` = slug + a `metadata: {node_type, type, originSessionId}` block — instead of flat `type:`/`originSessionId:`, so auto-applied memories load and categorize correctly. 134 tests (up from 132).
+- **v0.6.1** — new `file_reread` signal (MOSS §1 harness self-modification, proposed and approved through ADAM's own `/reflect` loop). Consecutive Reads of the same file at different `offset`/`limit` escaped `retry_loop`'s arg-hash dedup and leaked into `tool_error_loop`; `file_reread` now catches them (same file ≥3× in the 10-event window, offset-agnostic, guarded against double-counting byte-identical reads). Fully wired: detection (`adam-observe.mjs`), 14-day window (`adam-window.mjs`), severity divisor 3 (`adam-score.mjs`), file-basename clustering (`adam-batch.mjs`), and the analyst rubric/spec. 132 tests (up from 126).
+- **v0.6.0** — review hardening. Struggle signals now emit `active_skills`, so `silent_drift`'s primary cluster key and the §5b skill-attribution sub-clustering (+1 rubric bonus) actually fire (both were silently dead). `proposal_fingerprint` is now deterministically computable via `adam-cooldown.mjs --compute` instead of asking the LLM analyst to hand-compute a djb2 hash; spec now mandates a *stable* cluster id so fingerprints reproduce across runs. `reinforcement` proposals are correctly excluded from A/B tracking (the spec previously contradicted itself). `adam-nudge.mjs` pending-upgrade check now mirrors the full install set (`adam-utils`/`adam-batch`/`adam-rollback` were missing). Doc/test-count drift corrected. 126 tests (up from 114).
+- **v0.5.0** — MOSS-grounded self-evolution (arXiv 2605.22794). Transcript capture: `context_window` field on struggle signals captures 8 surrounding events for evidence-based diagnosis. Two-stage analysis pipeline: diagnose+plan → inter-stage validation → implement (§3.3). Evidence batching via `adam-batch.mjs`: pre-clusters journal into coherent failure batches (§3.1). Pre-apply verification: 4-check deterministic gate before auto-apply (§3.4). Auto-rollback via `adam-rollback.mjs`: reverts regressed proposals detected by A/B measurement, creates regression nudges (§3.5). Harness self-modification: new `harness_edit` proposal type lets ADAM propose edits to its own scripts with test-suite-gated apply (§1 Table 1). Keypoint matrix: 5 capability dimensions scored per batch for structured evaluation (§4.2). 114 tests (up from 94).
+- **v0.4.0** — expanded struggle detection: `silent_drift` (5 consecutive read-only tools), `error_after_recovery` (same error fingerprint returns after clean recovery); severity-sum scoring with per-type divisors; extended `STRUGGLE_TYPES` set. 94 tests (up from 87).
+- **v0.3.3** — analyst observability, A/B measurement, journal hygiene. ISO-week journal rotation replaces 5MB size-based (fixes silent cluster-straddling under-count); per-signal sliding windows via `adam-window.mjs`; error fingerprint normalisation; correction corpus expanded + weak-token co-occurrence requirement (kills the `"actually, I think..."` false positive); mandatory clustering trace + `adam-explain.mjs`; new `nudge` and `reinforcement` proposal types; per-(skill, fingerprint) cooldown via `adam-cooldown.mjs`; `task_completed` scoring (dampener + reinforcement); A/B effectiveness measurement; upgrade UX overhaul (`adam-upgrade.mjs --list/--diff/--accept`); shared `adam-utils.mjs`. 87 tests (up from 30).
+- **v0.3.2** — `task_completed` signal: post-task skill capture for downstream reinforcement scoring (consumed in v0.3.3).
+- **v0.3.1** — code review pass: bug fixes (`errorFingerprint` no longer false-positives on `is_error: false`, archive script handles same-millisecond duplicates correctly, `tool_window` clears on session change, nudge filters proposal filenames by pattern), prose conciseness cuts, hardened `install.sh` with curl one-liner + settings.json merge, `adam-uninstall.sh`, isolated test harness.
+- **v0.3.0** — causal diagnosis: every proposal carries a `# Diagnosis` block (Trigger/Action/Mismatch/Outcome with verbatim transcript quote), plus `contradiction_flag` heuristic that vetoes auto-apply on obviously-conflicting `skill_edit` additions.
+- **v0.2.1** — win signals (`correction_free_streak`, `clean_recovery`) feed `skill_edit` auto-apply under a strict gate (≤ 30 LOC, ≤ 2× byte cap, 7d cooldown, 30d blacklist).
+- **v0.2.0** — actioned-entry archival via `adam-archive.mjs`; `cursor` field deprecated.

 ## Requirements

- Claude Code v2.1.0+ (for auto skill hot-reload; older versions need session restart after `skill_new` proposals are applied)
- Node.js 18+ (for the hook; tested on v22)
- Bash 4+, `git`, `curl`, `jq` (for installer + test harness)
+- **Claude Code v2.1.0+** — for auto skill hot-reload (older versions need a session restart after `skill_new` proposals).
+- **Node.js 18+** — tested on v22, used by the hook + helper scripts. Zero npm dependencies.
+- **Bash 4+**, `git`, `curl`, `jq` — for the installer + test harness.

 ### Platform support

-Tested on **macOS** (Darwin / BSD coreutils) and **Linux** (Alpine, glibc + musl). The install / uninstall / test scripts are written to be portable: `stat` uses BSD `-f` with GNU `-c` fallback, `mktemp -d -t prefix.XXXXXX` works on both, no GNU-only flags. CI smoke verified `27 passed, 0 failed` under `alpine:latest`.

-## Confidence rubric
-
-```
-Sum:
-+2  Signal repeated ≥3× across ≥2 sessions
-+2  Struggle signal appearing ≥1× within a single session (does not stack)
-+2  Transcript contains positive endorsement near related action
-+1  Multi-axis cluster (≥2 distinct struggle types in same session)
-1  Type-bias penalty (≥3 rejections, applied:rejected <1:2)
-+1  Blast radius low (memory or new isolated skill)
- 0  Blast radius medium (new agent, new hook, edit existing skill)
-1  Blast radius high (CLAUDE.md, settings hooks, edit agent, deletion)
-+1  Surgical (one file, ≤50 LOC for non-skill_new; ≤80 LOC for skill_new)
-3  Touches deny-list (settings.json hooks/permissions, CLAUDE.md, deletions)
-
-auto_apply_eligible requires ALL:
-  confidence ≥ 4
-  blast_radius == low
-  type ∈ {memory, skill_new, skill_edit}     # skill_edit also passes the win-driven gate
-  cross_session_evidence == true (single-session-only proposals always queue)
-
-skill_edit additionally requires (v0.2.1+):
-  win-signal evidence (correction_free_streak / clean_recovery cites target skill)
-  diff is append-only, ≤30 LOC, resulting size ≤2× original
-  no auto-edit to same target in past 7 days (cooldown)
-  no rejection-blacklist on target in past 30 days
-  contradiction heuristic does not flag (v0.3.0+)
-  # Diagnosis section present + structurally valid (v0.3.0+)
-```
-
-## Lifecycle: how proposals become permanent
-
-Every proposal records the journal entry timestamps that fed its cluster (`source_entries` in frontmatter). When you apply or reject a proposal, the skill calls `adam/scripts/adam-archive.mjs` which moves matching entries from `journal.jsonl` to `journal/actioned-<id>.jsonl`. Effects:
-
- The `journal.jsonl` stays bounded by **active** observations only.
- The next `/reflect` reads applied/ + rejected/ frontmatter, builds an excluded-timestamps set, and skips any leftover journal entries that were already actioned.
- Rule changes (e.g. lowering a threshold) immediately re-evaluate the remaining active observations — no manual cursor rewind needed.
-
-## What it will not do
-
- No background LLM spend. The analyst runs only when you invoke `/reflect`.
- No retroactive transcript mining beyond the journal cursor.
- No hard `rm` of any artifact. Deletions are soft (`mv` to `trash/<ts>/`).
- No autonomous edits to `CLAUDE.md`, agents, hooks, or `settings.json` — these always queue for review regardless of confidence.
- No proposal that matches a previously-rejected idea (≥2 token overlap with rejection's `# Why`).
- No invented trigger phrases for new skills — every trigger comes from observed user input.

 You analyse Claude Code's own behaviour to propose targeted, surgical improvements. You operate offline (no LLM round-trips outside this run) and produce **files**, not actions. Main-thread Claude reviews and applies changes with the user.

+## Stage mode
+
+The skill dispatches you in one of two stages (MOSS-inspired multi-stage pipeline — §3.3: "a single prompt asked to diagnose, plan, implement, verify, and decide overloads context and produces lower-quality output than a sequenced flow"):
+
+- **`stage=diagnose`**: Read batched journal entries, cluster, diagnose root causes, plan fix types. Output diagnoses JSON to `/tmp/adam-diagnoses.json`. Do NOT draft proposals.
+- **`stage=implement`**: Read approved diagnoses from `/tmp/adam-diagnoses.json`. Draft full proposal files to `proposals_dir/`. Emit the clustering trace and punch list.
+
+If no `stage` is specified in the dispatch prompt, run **both stages sequentially** within a single pass (backward-compatible with pre-MOSS flow).
+
+### Diagnose-stage output format
+
+When `stage=diagnose`, write `/tmp/adam-diagnoses.json` containing:

+
+The skill validates diagnoses between stages (see SKILL.md §2 "Inter-stage validation").
+
+## Context window evidence
+
+Journal entries for struggle signals now carry a `context_window` field — an array of the last 8 events (user prompts, tool calls, responses) surrounding the friction point. This is the ADAM equivalent of MOSS's "original transcript captured by auto-scan at evidence time" (§3.4).
+
+When drafting diagnoses, **prefer `context_window` evidence over transcript file lookups** when it is present. The `context_window` is already scoped to the friction point and more reliable than file-based transcript pulls. Fall back to `transcripts_root` only when `context_window` is absent (pre-upgrade entries).

+- Cluster severity-sum ≥ 32: **+1** *(additive — a severity-sum of 32 gets +1 from the previous bullet AND +1 here, total +2.)*
+- Skill-attributed sub-cluster (≥3 entries naming the same `active_skills[0]` that exists in `skills_root`): **+1**

 ### `nudge` proposals
@@ -363,6 +495,42 @@ A `reinforcement` proposal is logged when `adam-score.mjs` reports `count >= 3`

 Note that `task_completed` alone — without an adjacent negative signal cluster — is NOT a proposal source. It is a urgency *modifier* (see "Scoring: task_completed dampener") and a reinforcement input only.

+### `harness_edit` proposals (MOSS §1 Table 1)
+
+MOSS's core thesis: "routing, hook ordering, state invariants, and dispatch live in code rather than in any text artifact, an entire class of structural failure is physically unreachable from the text layer." This proposal type extends ADAM's evolution scope to its own harness.
+
+**Allowed targets** (harness files that ADAM may propose edits to):
+
+| target | what it controls |
+|---|---|
+| `~/.claude/adam/scripts/adam-observe.mjs` | signal detection regexes, thresholds, counters |
+| `~/.claude/adam/scripts/adam-score.mjs` | severity divisors, dampener thresholds |
+| `~/.claude/adam/scripts/adam-window.mjs` | per-signal sliding window durations |
+| `~/.claude/adam/scripts/adam-batch.mjs` | evidence batching logic |
+| `~/.claude/agents/adam.md` | this agent's own rubric, clustering, proposal rules |
+| `~/.claude/hooks/adam-observe.mjs` | hook integration, event routing |
+
+**Gates (all must hold — stricter than any other type):**
+
+1. `confidence ≥ 5`
+2. `cross_session_evidence == true` (≥5 occurrences across ≥3 sessions)
+3. `auto_apply_eligible: false` — **always**. Harness edits are never auto-applied.
+4. `blast_radius: high`
+5. Proposal includes a `# Test verification` section with the command `bash ~/.claude/adam/tests/run-tests.sh` and the expected result "140 passed, 0 failed" (or current pass count). The skill runs this test before applying.
+6. Change is surgical: ≤30 LOC diff, single file.
+7. `# Diagnosis` reconstructs the causal chain from harness-level behavior (not from text-artifact behavior). The mismatch must name a specific code path (function, regex, threshold) in the target file.
+
+**When to propose `harness_edit`:**
+- Signal detection misses a recurring friction pattern (false negative in adam-observe.mjs)
+- A/B measurement shows systematic bias (e.g., windows too short/long in adam-window.mjs)
+- Scoring thresholds produce consistently over/under-weighted proposals (adam-score.mjs)
+- Batch clustering produces too-coarse or too-fine groupings (adam-batch.mjs)
+
+**When NOT to propose `harness_edit`:**
+- The fix is achievable via a text-mutable type (skill, memory, nudge)
+- Evidence is from a single session only
+- The change would affect test outcomes without clear improvement evidence

-### 2. Dispatch the analyst
+**Auto-rollback** (MOSS §3.5): if any entries have `status == "regressed"`, run the rollback script to auto-revert them before analyst dispatch:

-Use the Agent tool with `subagent_type: "adam"` and prompt:
+```bash
+node ~/.claude/adam/scripts/adam-rollback.mjs --auto --home ~/.claude > /tmp/adam-rollback-results.json 2> /tmp/adam-rollback.log
+```
+
+For each rolled-back proposal, print to user: `adam: rolled back "<proposal_id>" — regression detected (delta: <delta_pct>%)`. The rollback script moves the proposal from `applied/` back to `proposals/` with `rolled_back: true` and creates a regression nudge. If the script fails: log stderr, continue (rollback is best-effort).
+
+**Evidence batching** (MOSS §3.1): pre-cluster the windowed journal into coherent failure batches:
+
+```bash
+node ~/.claude/adam/scripts/adam-batch.mjs --input /tmp/adam-windowed-journal.jsonl > /tmp/adam-batches.json 2> /tmp/adam-batch.log
+```
+
+This groups entries by (signal_type, cluster_key) and reports per-batch metadata including `has_context_window` (whether transcript evidence is attached). If the script fails: log stderr, pass `null` to the analyst (graceful degradation — analyst falls back to raw journal clustering).
+
+**Skill utility** (execution-grounded selection signal, in the spirit of SkillsInjector arXiv 2605.29794 — utility Δ(s), not surface match): compute per-skill good:bad outcome ratios over the windowed journal:
+
+```bash
+node ~/.claude/adam/scripts/adam-skill-utility.mjs --input /tmp/adam-windowed-journal.jsonl --json > /tmp/adam-skill-utility.json 2> /tmp/adam-skill-utility.log
+```
+
+This ranks skills by how often they co-occur with positive (`task_completed`, `clean_recovery`, `correction_free_streak`) vs negative outcome events, surfacing skills below the baseline positive rate (with sufficient sample) — advisory candidates for description disambiguation or archival. **CO-OCCURRENCE, NOT CAUSATION**: display the worst 3 below-baseline skills (`lift < 0`, not low-sample) to the *user* as a one-line advisory before listing proposals (e.g. `skill-utility: chezmoi 9% pos n=85, ghostty-config 14% pos n=50, …`). Do NOT feed this into the analyst's proposal machinery or auto-draft skill-archival from it — the human decides. If the script fails: log stderr, skip (best-effort).
+
+### 2. Dispatch the analyst (two-stage pipeline)
+
+MOSS §3.3: "A single prompt asked to diagnose, plan, implement, verify, and decide overloads context and produces lower-quality output than a sequenced flow." The analyst is dispatched in two stages with a validation gate between them.
+
+**Stage 1 — Diagnose + Plan**: Use the Agent tool with `subagent_type: "adam"` and prompt:

+**Inter-stage validation** (§2a): after stage 1 returns, read `/tmp/adam-diagnoses.json` and validate each diagnosis:

+2. Every diagnosis has all four fields (`trigger`, `action`, `mismatch`, `outcome`).
+3. The planned `type` is a valid proposal type.
+4. Remove diagnoses that fail validation — log a one-line warning per removal.
+
+If all diagnoses are removed or the file is missing/empty, print "adam: no valid diagnoses — nothing to implement" and skip to §6.

Derived from $VERSION / piped REF / `git describe --tags`. - adam-nudge.mjs (SessionStart) compares .version against the latest GitHub release at most once/day. Cached in ~/.claude/adam/.update-check.json; the cache drives an instant nudge (no network on the hot path) and is refreshed best-effort with a 1.5s AbortController cap. fetch unavailable / offline / timeout / rate-limit / parse error all degrade to silent no-op. Opt out with ADAM_NO_UPDATE_CHECK=1. main() is now async; never blocks SessionStart. - README: "Staying up to date" section; pin example bumped to v0.6.3. Tests: 134 -> 138. Notifier verified fully offline (cache-driven): nudges when a newer release is cached, silent when current, suppressed by the opt-out env, and no-ops when the .version marker is absent.	2026-05-29 13:13:59 +01:00
lukaszraczylo	d929101af4	fix(v0.6.2): A/B volume normalization + memory frontmatter schema Two issues surfaced by running ADAM's /reflect loop on a large real journal (4015 entries, 119 sessions) — both caused false/broken auto-apply behavior. 1. A/B over-reported regressions (adam-ab-measure.mjs). Regressions were measured on RAW originating-signal counts pre vs post. On a busy, growing journal almost every signal count rises post-apply regardless of whether the proposal helped — so the loop flagged 9 false "regressions" (and would auto-roll-back good proposals). Now the delta is computed on the signal's SHARE of total activity (rate = count / window-total). Falls back to the raw-count delta when the signal is the only activity in the window (preserves prior behavior + all existing A/B tests). Output adds raw_delta_pct, pre_total, post_total, normalized for transparency. 2. Memory frontmatter drift (agents/adam.md, SKILL.md). The drafting protocol emitted flat `type:`/`originSessionId:` with a prose `name`, but the live auto-memory store uses `name` = slug plus a `metadata: {node_type, type, originSessionId}` block. Auto-applied memories could fail to load/categorize. Protocol + apply-time validation now require the live metadata.* schema and cross-checking against an existing file. Tests: 132 -> 134. New: volume growth (raw +200%) with flat activity-share classifies neutral, not regressed; a genuine share increase still classifies regressed.	2026-05-29 12:37:10 +01:00
lukaszraczylo	3a54d7d3e1	feat(v0.6.1): file_reread signal — catch offset-shifted same-file re-reads Proposed and approved through ADAM's own /reflect harness_edit loop (MOSS §1): the analyst surfaced 23 tool_error_loop entries across 4 sessions whose context windows were really redundant re-reads of one file. retry_loop keys on argsHash of the full tool_input (including offset/limit), so consecutive Reads of the SAME file at different offsets escaped dedup and leaked into tool_error_loop fingerprints. The new file_reread signal catches them: same file Read >=3x in the 10-event window, offset-agnostic (keyed on file path), guarded by `sameToolArgs < RETRY_THRESHOLD` so byte-identical reads stay with retry_loop (no double-count). Fully wired end-to-end (not a half-dead signal): - adam-observe.mjs: detection + STRUGGLE_TYPES membership (so it carries context_window + active_skills like other struggle signals). - adam-window.mjs: 14-day sliding window (task-local, like retry_loop). - adam-score.mjs: severity divisor 3. - adam-batch.mjs: file-basename clustering. - agents/adam.md + README: signal tables, clustering rules, rubric, windows. Tests: 126 -> 132 (file_reread fires on 3x offset-shifted reads, not on 2x; byte-identical reads route to retry_loop not file_reread; carries context_window).	2026-05-29 11:31:50 +01:00
lukaszraczylo	4b36d6c09e	feat(v0.6.0): review hardening — live active_skills clustering, computable fingerprints Full codebase review (multi-agent, adversarially verified) surfaced several documented-but-dead mechanisms and doc/code drift. Fixes: - adam-observe: struggle signals now emit `active_skills`, so silent_drift's primary cluster key AND §5b skill-attribution sub-clustering (+1 rubric bonus) actually fire — both were silently dead (no struggle signal carried the field). - adam-cooldown: new `--compute` CLI deterministically derives proposal_fingerprint. The exported computeProposalFingerprint() was never called and the analyst was told to hand-compute a djb2 hash it cannot reproduce. Spec now mandates a stable cluster id so fingerprints reproduce across /reflect runs. Removed one dead normalization line. - spec: reinforcement proposals excluded from A/B tracking — agents/adam.md contradicted itself (:376 included, :476 excluded); SKILL.md aligned. - adam-nudge: PENDING_CHECK_PATHS now mirrors the full install set (adam-utils / adam-batch / adam-rollback were missing). - adam-explain: synthesized clustering summary carries `regressions: 0` (structural consistency with parsed summaries). - docs: test-count drift (87/94 -> 126) and "350-line hook" (-> ~600) fixed; adam-score header documents severity_sum/severity_by_type; adam-batch §4 reference corrected. Tests: +12 assertions (114 -> 126), all green. New regression tests cover the active_skills fix and --compute, plus boundary gaps the review flagged: retry_loop/weak_agent thresholds, A/B exact +/-25% deltas, cooldown 30d blacklist edge.	2026-05-29 01:57:44 +01:00
lukaszraczylo	2d9257922f	docs: update README for v0.5.0 release — MOSS-grounded improvements	2026-05-24 11:19:15 +01:00
lukaszraczylo	440fb52eb1	feat: apply MOSS-grounded self-evolution improvements to ADAM Implements 7 improvements grounded in MOSS paper (arXiv 2605.22794): 1. Transcript capture (§3.4): context_ring buffer in adam-observe.mjs captures last 8 events around struggle signals as context_window. 2. Evidence batching (§3.1): new adam-batch.mjs pre-clusters windowed journal entries into coherent failure batches by (signal_type, cluster_key). 3. Multi-stage analysis (§3.3): SKILL.md dispatches adam agent in two stages (diagnose+plan → implement) with inter-stage validation gate. 4. Pre-apply verification (§3.4): 4-check deterministic gate before auto-apply (source entries exist, diagnosis grounded, type-evidence match, no conflicting recent proposals). 5. Auto-rollback (§3.5): new adam-rollback.mjs reverts regressed proposals detected by A/B measurement, creates regression nudges. 6. Harness self-modification (§1 Table 1): new harness_edit proposal type targeting adam's own scripts with stricter gates (confidence≥5, never auto-apply, test-suite-gated). 7. Keypoint matrix evaluation (§4.2): 5 capability dimensions (tool_selection, scope_discipline, error_recovery, first_attempt, build_reliability) scored per batch for structured evaluation. Test suite: 94 → 114 tests (20 new), all passing.	2026-05-24 11:15:32 +01:00
lukaszraczylo	a48c705c0a	feat(adam): smarter signals & clustering - New signal types in hooks/adam-observe.mjs: - silent_drift: 5 consecutive read-only PostToolUse without an action tool - error_after_recovery: same error fingerprint returns within 5 events of clean_recovery - Severity-weighted scoring in adam/scripts/adam-score.mjs: - SEVERITY_DIVISORS exported per struggle signal type - Per-session severity_sum + severity_by_type added to JSON output - Skill-attribution clustering in agents/adam.md: - Sub-cluster struggle signals on active_skills[0] - New struggle-driven skill_edit variant (always queues, never auto-applies) - Rubric updates: - +1 for cluster severity-sum >= 10, additional +1 for >= 32 - +1 for skill-attributed sub-cluster naming an existing skill - silent_drift + error_after_recovery added to struggle signal list - Window: silent_drift 14d, error_after_recovery 30d - Tests: 94 passing (78-82 new) Backward compat: entries without count default to severity 1. Existing win-driven skill_edit gate untouched. No journal migration.	2026-05-13 19:21:59 +01:00
lukaszraczylo	a8883aa8b7	fix(logo): explicit light/dark variants + <picture> for GitHub The prior logo.svg used currentColor, which resolves to black when the SVG is loaded via <img> on GitHub — making the logo invisible in dark mode (the GitHub default for many users). Fix uses GitHub's supported <picture> + prefers-color-scheme media- source pattern in README: - assets/logo-light.svg — explicit GitHub light-theme text color #24292f - assets/logo-dark.svg — explicit GitHub dark-theme text color #f0f6fc - assets/logo.svg — kept with embedded @media + currentColor for standalone use (markmorph notes, anywhere else the SVG is loaded outside <picture>) README updates the <img> tag to a <picture> with media-conditioned source so GitHub's renderer picks the right variant per theme.	2026-05-13 02:07:11 +01:00
lukaszraczylo	7ed2aecdfa	docs(logo): swap to swaddled-baby design with hands Replaces the geometric-A-with-observation-dot with a softer, more on-theme design: a swaddled-baby silhouette (rounded A-shape bundle), face nestled inside, and the wrap-band extended past the bundle on both sides as little hands. Maintains currentColor + zero external assets; reads cleanly down to favicon size. Ties the visual identity to the 'Story behind Adam' section: the project is named after the author's son, and now the logo is too.	2026-05-13 02:02:02 +01:00
lukaszraczylo	a30f8b1158	docs: replace ASCII pipeline diagram with mermaid flowchart GitHub renders mermaid natively. Diagram now shows three subgraphs (Observation → Analysis → Review + apply) with a nested Pre-processors subgraph inside Analysis. Includes: - Dotted edge labeled 'user runs /reflect' marking the observe→analyze boundary. - Diamond gate node for auto-apply decision (conf≥4 · low blast · cooldown cool) with explicit yes/no branches. - Feedback loop: applied/ entries measure back into adam-ab-measure.mjs on subsequent reflects. - Color-coded classDef for stores (blue), processes (orange), and the clustering trace artifact (purple). ASCII art retired — diagram now legible at any zoom on github.com.	2026-05-13 01:54:38 +01:00
lukaszraczylo	d3e4350d71	docs: modernize README + add SVG logo + inspiration story - New 'Story behind Adam' section at the top: the project is named after the author's newborn son, whose observe-act-adjust-observe-again learning loop is the methodology ADAM applies to LLM sessions. - New SVG logo at assets/logo.svg: stylized 'A' with a captured observation point inside the apex and a feedback crossbar. Uses currentColor + gradient so it adapts to light/dark GitHub themes. - Centered header block with project tagline + 5 badges (License, Version, Tests, Node, Platform). - New 'Highlights' section: 8 emoji-tagged one-liners covering the v0.3.3 design pillars (zero LLM cost observation, A/B measurement, sliding windows, observability, etc.). - New 'How it works' ASCII pipeline diagram: observation -> analysis pre-processors -> analyst -> review + apply. - Signals table now includes per-signal sliding window column. - Rubric section restructured: gates, modifiers (dampener), and skill_edit-specific requirements clearly separated. - New 'Inspecting the analyst's reasoning' section documenting adam-explain.mjs + /reflect --explain. - Layout updated for v0.3.3 state files (active-nudges.json, ab-tracking.jsonl, reinforcements.jsonl, last-trace.txt) and all 9 new helper scripts under adam/scripts/. - Test count: 27 -> 87. - Closing line crediting Adam.	2026-05-13 01:50:59 +01:00
