Agent Reap

Dead agent sessions leave behind heredoc interpreters and shell-snapshot jobs reparented to launchd, spinning at 100% CPU with nobody left to read their output. This skill finds them with explainable rules and kills only what the user explicitly approves.

Workflow

Resolve the checkout explicitly; never assume the caller's cwd:

DOTFILES_DIR="${DOTFILES_DIR:-$HOME/work/dotfiles}"
test -f "$DOTFILES_DIR/scripts/agent_reap.py"

Scan (read-only): python3 "$DOTFILES_DIR/scripts/agent_reap.py".
- Lower the CPU floor when hunting quieter leaks: --threshold 30
- --json for machine-readable output.
Show the candidate table to the user. Each row carries a rule tag explaining why it was flagged:
- ORPHAN-INLINE — old, high-CPU ppid 1 interpreter running inline code (python -c, sh -c, …); both the CPU and --min-age gates must pass.
- AGENT-CHILD — long-running high-CPU descendant of a live agent process or a Claude shell-snapshot job.
- ORPHAN-CPU — ppid 1 CLI tool (non-app, non-system) pegging the CPU.
Never kill without explicit user confirmation. Present the exact PID list (AskUserQuestion works well) — AGENT-CHILD rows belong to a session that is still alive, so name which session loses the work before asking.
Kill only the approved pids: python3 "$DOTFILES_DIR/scripts/agent_reap.py" --kill --pids <approved,comma,separated>
- Add --force only if SIGTERM survivors remain.
Re-run the scan to verify, and report reclaimed CPU.

Safety properties (already enforced by the script)

--kill refuses any pid not in the current candidate set.
Agent main processes (claude/codex/omx/omc) are never candidates.
The script's own session subtree is never a candidate, but sibling agent sessions under the same multiplexer (cmux) are still scanned.

korean-technical-terminology

voidmatcha/dotfiles

Review and edit Korean technical docs, READMEs, UI copy, and prompts when terminology sounds machine-translated or a canonical English term was unnecessarily translated. Classify each disputed term as canonical English to preserve, established Korean to keep, or an awkward calque to rewrite naturally. Also strips surface AI-tell symbols from Korean prose — em/en dashes and spaced --, arrows (→), curly/smart quotes, ellipsis (…), and middle-dot (·) bullets or noun enumerations. Use for 기술 용어, 번역투, 직역, 영어로 써야 할 표현, 원어 유지, 한글화가 어색함, 용어 통일, 화살표 제거, em대시 없애, 가운뎃점 없애, AI 티 기호, AI slop 기호, Korean technical writing, or terminology review. Do not use as a general spelling or tone checker.

asset-improver

voidmatcha/dotfiles

Auto-research and improve a repo's skills, hooks, and scripts: external real-world web research + internal audit + Codex cross-model verification, behind a propose then approve then apply gate with freeze-on-success and auto-revert. Use when asked to improve, audit, harden, or research-improve skills/hooks/scripts in the current repo.

agent-reach

voidmatcha/dotfiles

Use public web, GitHub, social/community, video, RSS, and career search surfaces from the CLI/MCP when local repo evidence is not enough. Routes to public-only research tools while avoiding internal/company URLs and secret-bearing pages.

agent-usage-audit

voidmatcha/dotfiles

Audit installed Claude/Codex agents, skills, commands, metadata-level reference counts, and source-level token pressure to decide what to prune, keep, or route. This inventory skill does not mine historical correction content or decide the current session's handoff state.

context-check

voidmatcha/dotfiles

Check Claude/Codex/OMX context, cache, headroom, and handover pressure; advise continue, compact, clear, or hand off.
