- Added SearchDb class for stateful shared search database instances enabling persistent file indexing and frecency tracking across grep, glob, and fuzzyFind operations.
- Added optional db parameter to grep(), glob(), and fuzzyFind() functions for database-backed searching with improved performance via cached file indices.
- Replaced grep-searcher with fff-grep and added fff-search dependency for enhanced file discovery and search capabilities with memory-mapped file support.
- Migrated fuzzy file discovery from fd module to fff module with SearchDb integration for stateful caching and improved search performance.
- Exported SearchDb type from @oh-my-pi/pi-natives public API for type-safe usage in grep, glob, and fuzzyFind workflows.
The grep, ast_grep, and ast_edit renderers used group-count-based
collapse that always included the first group unconditionally,
allowing collapsed output to remain visually large when a single
group contained many lines.
Add maxCollapsedLines to renderTreeList that enforces a strict
total-line cap in collapsed mode. Items that exceed the remaining
budget are skipped entirely (no broken fragments). The isLast tree
branch is computed after the budget check to avoid double-last
branches when a summary line follows.
Remove the per-tool getCollapsedMatchLimit / getCollapsedChangeLimit
helpers that are now redundant.
Fixes#455
Made-with: Cursor
- Added support for quoted paths in grep, ast_grep, find, and ast_edit tools to handle paths with spaces.
- Introduced normalizePathLikeInput() utility function for consistent path and glob parameter normalization across tools.
- Enhanced ast_grep error messaging to warn about parse issues and suggest narrowing path/glob or setting lang parameter.
- Added comprehensive tests for quoted path handling in grep, ast_grep, and find tools with pattern matching.
- Corrected error messages in ast-edit, ast-grep, grep, and find tools to reference the correct scope path variable instead of incorrect variable names.
- Added support for comma/space-separated path lists in find, grep, ast_grep, and ast_edit tools, allowing users to search multiple directories with a single query (e.g., 'apps/,packages/,phases/' or 'apps/ packages/ phases/').
- Added resolveMultiSearchPath and resolveMultiFindPattern utility functions to path-utils for intelligent parsing and resolution of multi-path search inputs with automatic common base path detection.
- Updated tool documentation for find, grep, ast_grep, and ast_edit to clarify that path parameters accept files, directories, glob patterns, or comma/space-separated path lists.
- Refactored path resolution logic in find, grep, ast_grep, and ast_edit tools to use unified multi-path handling with intelligent delimiter detection (comma or whitespace).
- Added `glob` parameter to `ast_grep`, `ast_edit`, and `grep` tools for filtering files relative to `path`.
- Implemented `combineSearchGlobs()` utility to merge glob patterns from multiple sources instead of throwing errors.

- Enhanced insert operation to support optional before/after anchors enabling flexible insertion positioning and boundary echo stripping.
- Made hashline autocorrect heuristics conditional on PI_HL_AUTOCORRECT environment variable for controlled behavior.
- Added benchmark reports for claude-haiku-4-5 and GPT-5.2-Codex models demonstrating hashline edit variant performance.
Hashline prefixes (LINE:HASH|content) in read/grep output exist solely to
support the hashline edit mode. Agents that don't have the edit tool
(e.g. explore, plan, reviewer) gain nothing from them — they just waste
tokens and add noise.
resolveFileDisplayMode now takes a session-like object with an optional
hasEditTool flag. When false, hashlines are suppressed regardless of
settings. ToolSession gains hasEditTool (set from toolNames in the SDK),
and AgentSession exposes it as a getter over the tool registry.
