Summary

Fixes Pi FFF query scoping and adds configurable default excludes:

  • preserves recursive directory globs like .predibase-buildenv/** instead of collapsing them to .predibase-buildenv/
  • adds a defaultExcludes config option for path constraints that should be excluded from every find / grep query
  • skips those default excludes when the query path explicitly targets one of them

Why

The current normalization collapses dir/** to dir/. In FFF query syntax that directory-prefix constraint can match the same directory segment anywhere in the indexed tree, so a query scoped to .predibase-buildenv/** can also match .worktrees/foo/.predibase-buildenv/**.

Configurable default excludes let users avoid stale or generated subtrees, such as local git worktree roots, without baking product-specific paths into the package. Explicit searches inside those paths still work.

Example config

{
  "defaultExcludes": [".worktrees/", ".claude/worktrees/"]
}

Validation

  • cd packages && bun run format:check
  • cd packages/pi-fff && bun test

Note: cd packages/pi-fff && bun run typecheck currently fails before this change on missing @ff-labs/fff-node type resolution plus existing implicit-any errors in src/index.ts.

Summary by CodeRabbit

  • New Features

    • Added configurable default exclusions for find and grep queries.
    • Queries automatically exclude configured paths unless searching within an excluded location.
  • Bug Fixes

    • Recursive directory patterns now retain their original glob format for more precise matching.
    • Exclusion patterns are normalized consistently, improving query results for paths such as test/**.

📝 Walkthrough

Walkthrough

buildQuery preserves recursive directory globs and adds configured default exclusions. It skips them when the path targets an excluded root. Configuration and search tools now support this option.

Changes

Query behavior

Layer / File(s) Summary
Default exclusion configuration
packages/pi-fff/pi-fff.schema.json, packages/pi-fff/src/config.ts
The schema and config loader now define and validate defaultExcludes as an array of non-empty strings.
Query normalization and exclusions
packages/pi-fff/src/query.ts, packages/pi-fff/test/query.test.ts
Recursive globs remain unchanged. buildQuery adds default exclusions unless the path targets an excluded root, then merges caller exclusions. Tests cover these cases.
Search tool integration
packages/pi-fff/src/index.ts, packages/pi-fff/test/config.test.ts
Startup configuration passes defaultExcludes to finder, grep, and find queries. Config tests cover valid and invalid values.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to a80b8

Inactive worktrees remain searchable when no configuration is provided, while configured recursive exclusions can incorrectly block explicit searches within those roots. The change is not ready to merge until both path-selection behaviors are corrected.

Set the built-in worktree exclusions here.

loadConfig() returns no value when the option is absent. This fallback keeps defaultExcludes empty, so normal fffind and ffgrep searches still include inactive worktrees. Use [".worktrees/", ".claude/worktrees/"] as the fallback, and set the same schema default.

Proposed fix
-    defaultExcludes = config.defaultExcludes ?? [];
+    defaultExcludes = config.defaultExcludes ?? [
+      ".worktrees/",
+      ".claude/worktrees/",
+    ];

Normalize configured exclusions before the target check.

defaultExcludes accepts recursive globs and comma-separated values. A value such as .worktrees/** does not prefix-match .worktrees/demo/**, so the default exclusion remains active and blocks the explicit search. Normalize each exclusion first, and handle a trailing /** as its directory root.
