omp-hooks v0.0.4

What's new

Parallel hook execution (Claude Code behavior)

• All matching hooks now run in parallel via Promise.allSettled
• Identical handlers deduplicated by command+args across groups
• Deny-wins: one deny/exit-2 blocks regardless of allow from others
• stopProcessing wins over deny; updatedInput merges in config order
• additionalContext concatenated in config order (deterministic)
• PostToolUse patches: first non-undefined content/details/isError wins
• Single-hook calls skip allSettled overhead

updatedToolOutput field (PostToolUse)

• extractToolResultPatch now reads Claude Code's actual updatedToolOutput field as the highest-priority content source
• Above legacy updatedToolResult.content and updatedMCPToolOutput
• This was effectively a bug fix — hooks using the documented Claude field were silently ignored before

Type cleanup

• CommonHookOutput named type (replaces ReturnType<typeof> usage)
• CollectedHook/HookExecResult named types for parallel helpers

omp-hooks v0.0.3

omp-hooks v0.0.3

Bug fixes and compatibility improvements over v0.0.2.

What's changed

Bug fixes

• Fix: inject additionalContext for SessionEnd, PreCompact, PostCompact, and non-blocked Stop hooks — these 4 event handlers collected additionalContext from hook command output but never injected it into the LLM. Now all events inject their additionalContext through injectHiddenContext, matching PreToolUse and PostToolUse behavior.
• Fix: case-insensitive exact matcher — matcherMatches('Read', 'read') was returning false because exact-match used === instead of case-insensitive comparison. Fixed by lowercasing both sides. Matters because Claude configs use "Read"/"Bash" while OMP may emit lowercase "read"/"bash".

Features

• Claude-compatible field aliases in buildHookInput — omp-hooks now emits both OMP and Claude Code field names in the hook JSON payload:

  • Glob: .path + .pattern (Claude Code uses .pattern)
  • Read/Edit/Write: .path + .file_path (Claude Code uses .file_path)
  • Read (URL): .path + .url + .prompt (some Claude scripts use .url/.prompt)
  • PostToolUse: .tool_response.content[].text + .tool_response.result (string)

  This eliminates the need for bridge scripts that only do field-name mapping. Plugin-specific routing (calling a specific binary or marketplace script) may still need a bridge.

Docs

• README rewrite — shorter, professional structure with install, quick start, supported subset tables, examples, and compatibility notes.

Verified

• bun run typecheck ✅
• bun run build ✅
• 64 unit/smoke tests ✅ (matcher, tool names, all events, execution, async, JSON output)
• Live session testing ✅ (19 omp-hooks injections in session JSONL, CBM/agent-skills/ponytail all firing)

omp-hooks v0.0.2

omp-hooks v0.0.2

Compatibility-focused patch release for Claude Code command hooks on OMP.

What's changed

• Normalize OMP tool names to Claude-style names for hook scripts and matchers (bash → Bash, write → Write, etc.) while preserving lowercase matcher compatibility.
• Match current Claude Code matcher semantics: omitted/empty/star match all, plain names exact-match, pipe/comma lists match exact alternatives, and regex syntax still works for patterns like mcp__.*.
• Add command exec-form support with args; when args is present, command is spawned directly without a shell.
• Add shell support for command hooks (bash by default, powershell supported for shell form).
• Add background command hook support with async and best-effort asyncRewake.
• Align default timeouts closer to Claude Code: 600s for command hooks, 30s for UserPromptSubmit, 1.5s for SessionEnd.
• Update README compatibility docs to describe the supported Claude command-hook subset and explicitly list unsupported handler types/events.

Still unsupported

• Handler types: http, prompt, agent, mcp_tool.
• Newer Claude events outside the mapped subset, including PostToolBatch, PermissionRequest, PermissionDenied, Notification, MessageDisplay, SubagentStart, SubagentStop, and StopFailure.

Verified

• bun run typecheck
• bun run build
• Direct smoke tests for matcher behavior, tool-name normalization, hook input shape, timeout defaults, shell-form execution, exec-form args, and async additionalContext delivery.

v0.0.1

omp-hooks v0.0.1

Claude Code-compatible command hooks for the OMP (Oh My Pi) coding agent.

Features

• 9 Claude Code hook events mapped (SessionStart, SessionEnd, PreCompact, PostCompact, PreToolUse, PostToolUse, PostToolUseFailure, UserPromptSubmit, Stop)
• Hidden context injection via sendMessage({ display: false }) — the mechanism OMP's native tool_call lacks
• Claude Code settings.json hooks config format compatibility
• Settings from ~/.omp/agent/settings.json (env-overridable via OMP_HOOKS_SETTINGS) + project-local <cwd>/.omp/settings.json
• Debounce buffer for parallel grep/glob injections (50ms window)
• Bridge-script compatible (bash -c + JSON stdin/stdout + exit-code semantics)

Install

omp install omp-hooks

Or from source:

omp install git:github.com/ZeR020/omp-hooks

Requirements

• OMP (Oh My Pi) coding agent
