Hooks (1)
hooks— PostToolUse, SessionEnd
Plugins in this marketplace (22)
context-hogs— Per-file context-cost leaderboard: attributes every tool result's tokens to the files it loaded, so you know which files cost you the most.cache-tax— The comeback price of a cold prompt cache, shown before you pay it: a UserPromptSubmit guard that warns (or refuses once) when your next message re-writes a lapsed 1-hour cache at up to 80x the read rate, a SessionStart hook that prices a stale resume, and a one-line status line segment with minutesnerf-receipts— A personal flight recorder for Claude Code quality: records your own per-session failure rate, edit churn, and tokens/task by model version, and flags real shifts when a model changes.dead-rules-audit— CLAUDE.md compliance scorecard: tallies which rules Claude actually follows vs ignores as you edit, and flags chronically-ignored rules to promote into a deterministic hook.pr-provenance-stamp— Stamps a provenance receipt (prompts, estimated spend, tests run with exit codes, and a truthful agent-authored line split) into your PR body on `gh pr create`.standup-autopilot— Writes your daily standup from what your agents actually did across repos: captures tasks, tests, PRs, and blockers from session transcripts and re-injects yesterday's open blockers next session.dead-end-registry— Remembers approaches you tried and reverted (with reason and estimated token cost) and warns before you retry them, via a prompt-submit card and an ask-before-edit guard.bounty-board— Prices your repo's TODO/FIXME/HACK debt as aging XP bounties, injects the top 3 as opportunistic side quests, and verifies + pays out bounties you genuinely clear.block-dangerous-commands— PreToolUse guard for Bash: blocks dangerous shell commands (rm -rf ~, fork bombs, curl|sh, force push to main) before they run, with three safety levels and opt-in per-level ask mode.protect-secrets— Secrets firewall for tool calls: denies (or asks, per level) any Read/Edit/Write/Bash/Grep that would read, search, modify, or exfiltrate .env files, SSH keys, cloud credentials, or keystores, with tiered safety levels tunable via HOOK_SAFETY_LEVEL.git-safety— Branch-aware git guardrails plus destructive gh CLI protection: denies pushes to main/master, protected-branch deletion, direct commit/merge/rebase/reset/push on a protected branch, and gh pr merge/close, issue close, release and repo delete.protect-tests— Stops "fake green" test-gaming: blocks the agent from deleting, renaming-away, or skip/xfail-disabling tests so it fixes the code instead, across pytest, jest, Go, JUnit, RSpec, and more.case-insensitive-guard— Stops `rm -rf content` destroying `Content` on case-insensitive filesystems (APFS/exFAT/NTFS): resolves the real target of destructive commands through cd chains, quotes, and subshells, and denies provable case collisions.config-guard— Who guards the guards: blocks the agent from tampering with its own guardrail config (settings.json, hook scripts, hooks.json, .mcp.json, plugin manifests, claude CLI config writes); reads always pass.subagent-spawn-cap— Per-session subagent spawn budget: a PreToolUse guard on the Agent tool that counts every spawn (nested fan-outs included) in an append-only ledger, asks at SPAWN_CAP_ASK (default 20) and every SPAWN_CAP_ASK_STEP after it (default 10), and denies at SPAWN_CAP_DENY (default 60). The total cap Claudeconfig-watch— Tripwire for out-of-band config changes: warns on every mid-session settings/skills change (or blocks it with CONFIG_WATCH_BLOCK=true) to catch installer scripts and npm payloads rewriting settings behind Claude Code's back.auto-stage— Automatic git staging: runs `git add` on every file Claude edits or writes, so `git status` always shows exactly what Claude touched and pre-commit review needs no manual staging.format-code— Auto-formats files the moment Claude writes them: ruff for Python, prettier for JS/TS/JSON/MD/YAML/HTML, with shell-injection-safe argv execution and silent skips for everything else.session-logger— Durable markdown log of every session (cwd, git repo, files touched, secret-redacted bash commands), appended async so logging never blocks Claude.instructions-audit— Prompt-injection tripwire for CLAUDE.md and .claude/rules files: flags invisible-Unicode smuggling, secret read/exfil directives, curl|sh, decode-and-execute, and hook/settings tampering as instructions load, then locks the session (every prompt and tool call denied) until a human clears it.notify-permission— Slack alerts when Claude Code needs you: posts a rich card (project, session, and what needs approval) to your webhook on permission, idle, and choice prompts.guard-pack— All seven guard hooks in one Node process: subagent-spawn-cap, config-guard, block-dangerous-commands, protect-secrets, protect-tests, git-safety, and case-insensitive-guard, first blocking verdict wins. One ~35 ms Node startup per tool call instead of seven. Do not install alongside the individual
