What it does
Install Hooks is an agent skill from sd0xdev/sd0x-harness. Install plugin hooks into project .claude/ for persistent use without plugin loaded
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development. The repository describes itself as: The harness layer for Claude Code — a reference implementation of harness engineering with hook-enforced dual review, state-machine gates that survive context compaction, and… The licence is MIT.
When your agent uses it
- Development work in your project
Example prompts
- “/install-hooks”
Requirements
- Pre-approved tools (allowed-tools): Read, Grep, Glob, Write, AskUserQuestion, Bash(mkdir:*), Bash(diff:*), Bash(git:*), Bash(ls:*), Bash(chmod:*), Bash(jq:*), Bash(node:*)
What it can do on your machine
Read from SKILL.md and the folder at commit c9a2036. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGrepGlobWriteAskUserQuestionBash(mkdir:*)Bash(diff:*)Bash(git:*)Bash(ls:*)Bash(chmod:*)
…and 2 more on the same allowed-tools line.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
nodegit
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Install Hooks loads about 1.1k tokens when it runs. Until then it costs about 24 tokens; SKILL.md has 366 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Workflow
Phase 0: Resolve mode; obsolete-set migration (first for non-list invocations; --dry-run forwarded)
Phase 1: Locate plugin hooks dir
Phase 2: Enumerate hook scripts
Phase 3: Determine install set (--all, specific names, or interactive)
Phase 4a: Copy scripts to .claude/hooks/
Phase 4b: Merge hook definitions into settings.json
Phase 4c: Update manifest
Phase 4.5: Backfill CLAUDE.md references
Phase 5: Output reportPhase 0: Obsolete-Set Migration
Resolve the invocation mode first — Phase 0 mutates settings and deletes files, so the
non-mutating modes must never reach it live: with --list, skip Phase 0 entirely (listing is
read-only); with --dry-run, forward the flag so the migration also only reports:
# --list → skip this phase
# --dry-run → append --dry-run to the command below
node "${CLAUDE_PLUGIN_ROOT}/scripts/migrate-hook-lightweighting.js" --repo "$(git rev-parse --show-toplevel)"Otherwise run the shared migration before any copy or merge — it is what removes the retired enforcement-layer files and their registrations (hook-lightweighting § 3.6), and running it first is what prevents the dangerous half-state (scripts-new + hooks-old).
Ordering inside the script is fixed: it deregisters settings entries first and deletes files only after the settings writes succeed; a failed settings write aborts (exit 1) before any deletion. On exit 1, stop the install and surface the report — installing on top of a repo whose deregistration failed reproduces the half-state the migration exists to prevent. Modified obsolete files are kept on disk (registration disabled) and named in the report; include those lines in Phase 5's output.

| Scripts | .claude/hooks/*.sh | Executable hook scripts |
| Definitions | settings.json hooks entries | Event → script path mapping |
Script dependencies: a locally installed hook resolves its helper scripts beside its own copy
(.claude/scripts/…), never from the plugin. The whole dependency surface is one checker —
scripts/review-state.js (which requires scripts/lib/tree-digest.js) — read by stop-guard.sh,
user-prompt-review-guard.sh and post-compact-auto-loop.sh (post-skill-auto-loop.sh is
deliberately zero-read: it prints one static gate-order line and consumes nothing). Missing →
every hook still runs and still reminds: it reports change-class facts from live git and claims no
verdict (nothing blocks — the hooks are reminders, hook-lightweighting § 3.2). Installing the
checker via /install-scripts --all (or /project-setup) is what upgrades the reminders from
"changed, verdict unknown" to "changed, reviewed at this tree".
