The default limits let broad queries flood the model context. This
change sets smaller defaults. An explicit parameter still overrides each one.
- file_search: max_results 1000 to 50, context_lines 2 to 0.
- ast_query: max_results 100 to 50.
- ast_query compact output omits the node type unless verbose is set.
On a fixed seven-call suite, response size fell from 198529 to 61960 bytes.
firstLineOf (query) and truncateString (edit) sliced strings at a raw byte
offset, splitting a multibyte UTF-8 character into invalid bytes in
LLM-facing output (ast_query compact format and edit not-found errors are
hot paths). Extract the rune-boundary backoff already used by search's
truncateLine into util.RuneBoundary and route all three sites through it.
Adds table-driven tests for the primitive and a multibyte case for firstLineOf.
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.
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.
* 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.
