 # Changelog
 
+## Unreleased
+
+- Add `PostToolUse` matching for MCP filesystem write, edit, and multi-read payloads.
+- Harden dynamic hook coverage for additional-context JSON output, disabled/static modes, failed tool responses, and duplicate suppression.
+- Remove redundant apply_patch path scanning and stale tracked-tool constants.
+- Use portable Codex hook interpolation and add package smoke coverage for hook entrypoints.
+- Cap recursive rule directory scans and run CI on Windows in addition to Ubuntu and macOS.
+- Replace the external glob matcher dependency with an internal matcher so clean Codex plugin installs run without `node_modules`.
+
 ## 0.1.0 - 2026-05-15
 
 - Port `pi-rules` rule loading, matching, formatting, truncation, and deduplication to a Codex plugin.

 It ports the `pi-rules` rule injector to Codex:
 
 - `SessionStart` and `UserPromptSubmit` load static project instructions once per session.
-- `PostToolUse` watches file reads and edits, then injects matching file-specific rules.
+- `PostToolUse` watches supported file reads, edits, `apply_patch`, MCP filesystem payloads, and shell command file references, then injects matching file-specific rules as additional context.
+- `PostCompact` clears the per-session injection cache after manual or automatic compaction so relevant rules can be reintroduced into the compacted conversation.
 - Session-level deduplication prevents the same rule from being repeated after it has been injected.
 
+`PostToolUse` output is context-only: it emits `hookSpecificOutput.additionalContext` and does not rewrite tool output.
+
+The runtime has no npm production dependencies, so a clean Codex marketplace copy can run without a follow-up `npm install`.
