claude-adam

Self-improvement layer for 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.

What it does

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

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.

Why

LLM coding sessions reveal repeated friction the moment you stop and look. ADAM looks so you don't have to.

Install

./install.sh

The script copies files into ~/.claude/. It does NOT modify your settings.json — wire the hook entries manually using settings.json.example as reference. Merging into existing settings prevents accidental clobber of your other hooks.

After install:

1. Run the test suite: bash ~/.claude/adam/tests/run-tests.sh — must show 18 passed, 0 failed.
2. Add the hook entries from settings.json.example to ~/.claude/settings.json (preserve your existing hooks; ADAM's are additive).
3. Restart Claude Code, or just run /reflect to trigger the skill — Claude Code v2.1.0+ auto-hot-reloads user-level skills, no restart needed.

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 (for the test harness)

Confidence rubric

Sum:
+2  Signal repeated ≥3× across ≥2 sessions
+2  Struggle signal repeated ≥3× within a single session (does not stack with above)
+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}
  cross_session_evidence == true (single-session-only proposals always queue)

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.

Uninstall

rm -rf ~/.claude/{hooks/adam-*.mjs,agents/adam.md,skills/adam-self-improvement,commands/reflect.md,adam}

Then remove the four adam-* hook entries from ~/.claude/settings.json.
