Two file_search gaps:
- max_results defaulted to 0 (unbounded), so a broad pattern returned every match — unbounded memory + token blowup. The configured MaxSearchResults (default 1000) existed but was dead; wire it as the builtIn default. Explicit max_results still wins, and the cursor footer pages the rest.
- search.Request.IncludeHidden was a dead field with no tool param. Add an include_hidden bool (default false) so dotfiles (.github/, etc.) are searchable.
ast_query defaulted to verbose output (full code + up to 500 chars/match + captures), which is very token-heavy on multi-match queries. Default to compact (one line per match: file:line (kind) firstline) — roughly 5-10x fewer tokens on typical queries — while verbose remains available per-call (format=verbose) or via the default_format session pref. Updates tool description, help resource, and TestASTQueryFormatCompactDefault.
handleASTQuery rebuilt the formatter's '[remaining: N]' placeholder string and strings.ReplaceAll'd it with the cursor line, plus a fallback append — fragile coupling to the formatter's exact output. New FormatResultsWithCursor appends the prebuilt '[cursor: ..., remaining: N]' footer in place of the bare hint when results are truncated; the handler just passes it through. FormatResultsWithOptions is unchanged (delegates with empty cursor). Adds TestFormatResultsWithCursor.
Two ast_query/lsp_query ergonomics improvements that share the tool registration and help files:
- lsp_query accepts symbol_name (+symbol_kind) and resolves the position via AST (resolveLSPSymbolPosition), so callers need not know line:col; line/column are no longer required. SymbolCandidate gains NameLine/NameColumn for the precise identifier position. Ambiguous/unknown names error with candidates / a 'did you mean' hint. Adds TestResolveLSPSymbolPosition.
- ast_query help + tool description now document that matching is keyword/kind-based, not structural: pattern arg/return constraints are not enforced; use name_exact/name_matches/kind_in to filter. Fixes a misleading 'functions returning error' example.
A misspelled or stale symbol_name returned a bare 'not found' error, forcing blind retries. nearestSymbolSuggestion fuzzy-matches the requested name against the file's actual symbols (via existing pkg/fuzzy) and appends 'did you mean: a, b, c?'. The re-parse is served from the parser cache. Adds TestReadSymbolNotFoundSuggestsNearest.
FindSymbolRange returned the first AST node matching a name, so file_read with symbol_name silently read the wrong symbol when a name collided (e.g. two String() methods on different receivers, or a func and type sharing a name). New FindSymbolCandidates returns all matches; the file_read handler now errors on ambiguity, listing each candidate's node type and line range so the caller can disambiguate via symbol_kind or line_start/line_end. FindSymbolRange is kept (first match) for callers that don't need ambiguity detection. Adds TestFindSymbolCandidates.
lspHover fell back to AST symbol info on any LSP error, but the '(AST fallback)' marker only showed when verbose=true. In the default mode the model received Node type/Text with no signal the answer was a degraded AST guess. Now always emit '[AST fallback — LSP unavailable]' so the model can decide whether to retry. Includes colocated QF1012 style fixups.
Two AST-summary/query path fixes plus colocated QF1012 style fixups:
- runASTQueryWalk now checks info.Size() > MaxFileSize before os.ReadFile, avoiding a full read of files it will discard.
- generateASTSummary used len(splitLines(...)) for the '(N lines)' header, over-counting newline-terminated files by one (phantom trailing element). New countLines() helper counts via bytes.Count. Adds TestCountLines.
Mechanical fix applied by golangci-lint --fix. Pre-existing debt that fails the staticcheck QF1012 quickfix check; no behavior change. Clears the lint gate so subsequent commits in this package set pass.
- [x] Remove auto-indentation from text mode edits (caller controls whitespace)
- [x] Add line-ending detection and normalization for both AST and text modes
- [x] Share edit logic via new `spliceContent` function for both modes
- [x] Fix diff to emit "No newline at end of file" markers
- [x] Fix diff to strip raw CR from CRLF file output
- [x] Remove double-unescape of backslash sequences in new_content
- [x] Fix countDiffLines to be hunk-aware (correctly count lines starting with +/-)
- [x] Fix block-comment stripping to remove standalone lines cleanly
- [x] Fix Python license header stripping to preserve separator blank lines
* v2.0: token-optimization overhaul
Additive (backward-compatible flags):
- file_read: skeleton mode, strip (imports/license/block_comments),
compact_line_numbers, 8-char etag with prefix-match compat
- ast_query: format=verbose|compact|location, pagination cursor
- file_search: cluster mode, pagination cursor
- lsp_query (references): compact output
Breaking (v2):
- Preambles removed; opt-in verbose=true restores
- edit_apply: response=count|diff|none, default count
- ping tool removed
- symbol_at/find_definition/find_references merged into lsp_query
- Tool descriptions trimmed -83%, help moved to filepuff://help/<tool>
- Batch file_read dedups by etag
Protocol:
- ResourceLink returned for file_read >64 KiB (force_inline override)
- OnAfterInitialize hook reads capabilities.experimental.filepuff
for session defaults (default_format, default_max_results,
default_cluster, compact_refs, line_numbers,
resource_link_threshold)
* fix: drop --max-total-count from ripgrep args
The flag does not exist in stable ripgrep (confirmed up to 15.1.0 --
"unrecognized flag --max-total-count, similar flags that are
available: --max-count"). Every file_search call failed on hosts with
stock rg. --max-count is per-file, not a drop-in replacement, so rely
on the in-process truncation in parseOutput that was already the
documented safety net.
