Three strip=imports/license correctness fixes (all heuristic, keyword/structure-gated):
- stripTSImports now tracks multi-line named imports (import {\n ... \n} from 'x') instead of dropping only the first line and leaving dangling members; side-effect imports without semicolons no longer trigger runaway consumption.
- stripGoImports recognizes all single-import spec forms: import _ "x", import . "x", and aliased import m "x" (previously only import "x"/backtick).
- stripLicense peels a leading shebang (#!) or Go build-constraint (//go:build, // +build) block and preserves it above the license, and now strips // line-comment license headers (not just /* */ and #). Adds tests for each.
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.
We advertise textDocument.definition.linkSupport=true, so gopls and rust-analyzer return the LocationLink shape (targetUri/targetRange). The old code only tried []Location then a single Location; unmarshaling LocationLink JSON into []Location silently succeeds with zero-value URIs/ranges, producing garbage locations (or a false 'No definition found'). parseDefinitionResult now decodes a unified shape capturing both field sets and normalizes to Location, and surfaces a real parse error instead of swallowing it. Adds TestParseDefinitionResult covering all shapes.
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.
extractErrors is a pure function of the parsed tree (it ignores content), so re-walking the whole tree on every cache hit wasted work on the hottest path (file_read+include_ast, ast_query, edit validation). Store []SyntaxError in CachedTree and return it directly on hits. Adds TestParseCachedErrorsMatch asserting cache-hit errors equal the cache-miss parse.
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.
