# skyhook-skills
Composable AI **dev-workflow and research** commands for [Claude Code](https://claude.com/claude-code), [Codex](https://github.com/openai/codex), and [Cursor Agent](https://cursor.com/docs/skills). An autonomous plan → implement → review → PR → converge loop, cross-model review, product/design/UX critique, and decision-focused competitive research.
Built by [Skyhook](https://skyhook.io) for building [Radar](https://github.com/skyhook-io/radar); generic enough to use anywhere.
## What you get
**The loop**
- **`/autodev [--auto] <task>`** — full autopilot: plan → implement → review → PR → converge, end-to-end, stopping only at real decisions. Default mode gates on the plan before coding; `--auto` makes product calls itself (logging assumptions) and stops only for an irreversible-action ceiling. A run ends with a **done audit** against an explicit definition of done on the PR's final commit — ask fully delivered, final code reviewed, `/product-review` passed for user-visible work, exercised as a user, CI green, zero unaddressed PR comments — and reports `done`, `waiting on you`, `not done`, or `blocked`.
- **`/plan-loop`** — draft a plan, cross-review it with the *other* model, triage the critique skeptically, iterate, gate.
- **`/review-loop`** — proactively review the current code (self + cross-model), triage, fix, update the PR — loop until clean.
**Review & critique** (three altitudes — *right thing* → *earning its keep* → *correct*)
- **`/product-review`** — questions *what* to build and *how* users perceive it: premise, top user journeys (ranked 0–10), UX shape, comprehension, states, AI-slop. Borrows forcing-function patterns from [gstack](https://github.com/garrytan/gstack) and [OneRedOak](https://github.com/OneRedOak/claude-code-workflows) + a journey-ranking + non-expert-comprehension lens.
- **`/review`**, **`/simple`** (anti-over-engineering), **`/triage-findings`**, **`/fix-findings`**.
**External contributions**
- **`/external-pr-review <GitHub URL> [focus]`** — assesses an outside contribution's premise and implementation, then recommends the shortest safe path to merge. Classifies findings as author changes, maintainer fixes, follow-ups, deferred work, or findings to drop.
- **`/external-issue-triage <GitHub URL> [focus]`** — drafts a timely acknowledgment, investigates a bug or feature request, and prepares a maintainer recommendation. Keeps public replies separate from private analysis.
Both default to review and recommendations; posting and contributor-branch changes need explicit authorization. They follow the project's documented scope rather than assuming a particular product policy.
**Cross-model review**
- **`/cross-review`** — runs a review by the configured secondary model — **Codex or Cursor** — prints it verbatim, then triages it skeptically (never auto-accepts). Pick the reviewer via `~/.claude/skyhook-skills.json` (`{"reviewer":"codex|cursor","model":"…"}`), the `SKYHOOK_REVIEWER` env var, or a `consult cursor` / `consult codex` directive. `/codex-review` forces Codex.
**PR**
- **`/pr`**, **`/fix-pr`**, **`/fix-pr-loop`** (reacts to CI + bot reviewers until converged: reads every feedback surface — review threads, review bodies, PR comments bots edit in place, check-run output — waits for reviewers to settle on the final commit, and resolves or answers every thread).
- **`/request-approval [now|1h|1d]`**: when a PR can't merge without a human approval, posts one line to the team's approvals Slack channel with an urgency level: `NOW` (blocking), `1H` (within the hour) or `1D` (within the day, the default). `/autodev`, `/fix-pr-loop` and a standalone `/pr` run it once the PR is ready for a human. The channel defaults to `#pr-approvals`; set `approvalChannel` in `~/.claude/skyhook-skills.json` or `SKYHOOK_APPROVAL_CHANNEL` to change it. Without a Slack integration it prints the line for you to post.
**Hand it over**
- **`/handoff [work order] <task>`** — writes a self-contained prompt for a fresh agent (a new Claude or Codex session, a teammate, a delegated worker) and copies it to the clipboard. Defaults to a discussion prompt that asks the receiver to review independently first; `work order` produces a spec with exact proof and an explicit stop-and-report exit for every hard rule.
- **`/review-packet [pr|set|design|research] [focus]`** — packages work for guided review: a document that first explains the change from first principles (the problem, how it works, why this design, alternatives and costs), then puts the evidence for every claim beside it and ends with the calls the reviewer has to make. Claude publishes an artifact; Codex publishes through Sites. Ask for local-only output to get self-contained HTML with embedded evidence (no PDF). If publishing is unavailable, the skill hands over HTML and explains the gap. Cursor defaults to local HTML. Built for large PRs, PR *sets*, rendered UI, and design or research proposals — the cases where review otherwise means scrolling a diff and taking your word for it.
**Research**
- **`/competitive-research [implementation|product|positioning|hybrid] [focus]`** — investigates how comparable products handle the active decision using primary evidence: OSS source and tests for implementation details, official product material for UX/features, or current first-party pages for positioning. Compares the tradeoffs with the current approach and recommends what to keep, adopt, hybridize, or defer.
**Utilities**
- **`/retro`** — session retrospective: finds the friction in this session (wrong approaches, repeated corrections, permission prompts, missing context) and proposes exact instruction, settings, command, and doc changes, applying only the ones you approve.
- **`/gpra`** — rebase the current branch over the remote default branch with `--autostash`; never resolves conflicts on its own and force-pushes (`--force-with-lease`) only after you confirm.
- **`/diagram`** — draws a diagram as an Excalidraw file and exports it to PNG.
- **`/housekeeping`** — read-only audit of a dev machine's disk, caches, stale tools, and services; triages findings into reclaimable / worth-reviewing / leave-alone and never mutates anything without explicit approval.
Cross-cutting: **never auto-accept a reviewer** (your own, the cross-model pass, or PR bots) — every finding is triaged with evidence; cross-review only when nontrivial; every loop caps and reports; review at altitude (a clean implementation of the wrong thing is still wrong).
## Concepts
A few principles run through every command:
- **Review at altitude, intent before details.** Before judging whether code is *correct*, judge whether it's the *right thing to build* and the *right design* — approach, architecture, UX, user journey. A clean implementation of the wrong thing is still wrong. `/product-review` is the dedicated pass for this.
- **Research at the task's altitude.** Competitive work should answer the decision in front of you: source-level evidence for implementation semantics, product evidence for UX and features, market evidence for positioning. Prefer representative patterns over exhaustive feature grids.
- **Never auto-accept a reviewer.** Every finding — your own, the cross-model pass, or a PR bot — is triaged against the real code, with evidence cited on every skip. Cross-model reviewers are often right about blind spots and often wrong about things already handled; you decide.
- **Compose, don't rebuild.** The loops are thin conductors over small, single-purpose commands. Edit one (e.g. `/triage-findings`) and every loop that uses it inherits the change.
- **Scale ceremony to the task.** Trivial changes skip the loop; nontrivial work gets cross-review + product critique. Steps are judgment calls, and you can steer them inline (`/review-loop consult codex`, `/autodev no PR`, `quick`, `focus on auth`).
- **Bring-your-own verification (`/qa`).** The loops call `/qa`, but each repo defines what verification means there — type-check, tests, and optionally a `/visual-test`. The workflow stays repo-agnostic.

## Install and update
Claude Code uses the plugin marketplace. Codex and Cursor Agent use the same
Agent Skill adapters and canonical command bundle under `~/.codex/skills`;
Cursor discovers that directory for compatibility, so installing for both does
not create two copies.
The Claude plugin exposes the full command catalog. Codex and Cursor expose the
companion entry points `autodev`, `plan-loop`, `review-loop`, `product-review`,
`claude-review`, `competitive-research`, `review-packet`, `handoff`,
`external-pr-review`, `external-issue-triage`, `retro`, `gpra`, and `diagram`; those skills use the shared
canonical commands internally.
| Agent | Distribution | Invoke a skill |
|---|---|---|
| Claude Code | `skyhook-skills` marketplace plugin | `/skyhook-skills:competitive-research` |
| Codex | User-level Agent Skills | `$competitive-research` |
| Cursor Agent | The same Agent Skills as Codex | `/competitive-research` |
### Claude Code
First install — run these **inside Claude Code**:
```text
/plugin marketplace add skyhook-io/skyhook-skills
/plugin install skyhook-skills@skyhook-skills
```
Update — run these in a terminal:
```bash
claude plugin marketplace update skyhook-skills
claude plugin update skyhook-skills@skyhook-skills
```
Then apply the update to an already-running Claude Code session:
```text
/reload-plugins
```
Use `/plugin` to browse installed commands or enable marketplace auto-update.
Third-party marketplace auto-update may be disabled, so the explicit update
commands above are the reliable path. See the
[Claude Code plugin documentation](https://code.claude.com/docs/en/discover-plugins).
### Codex
First install **and every update** use the same idempotent command:
```bash
curl -fsSL https://raw.githubusercontent.com/skyhook-io/skyhook-skills/main/scripts/install-codex.sh | bash
```
The installer fetches `main`, updates the Skyhook adapters and canonical
commands, and leaves unrelated skills alone. It prints the source revision and
each adapter's command reference, saves the revision in
`$CODEX_HOME/skills/skyhook-skills-commands/.source-revision` (`CODEX_HOME`
defaults to `~/.codex`), and warns about
same-name copies under `~/.agents/skills` or the default `~/.codex/skills` when
installing elsewhere. It does not delete those copies or determine which adapter
an agent loads. Check the selected skill's path when a command appears stale.
Custom `CODEX_HOME` installs also warn when an adapter references the default
`~/.codex/skills` command bundle. Sources without readable Git metadata install
with an explicit unavailable-revision warning.
Codex normally detects skill changes
automatically; if the update does not appear, restart Codex. Verify with
`/skills`, then invoke a skill with `$competitive-research`. See the
[OpenAI Agent Skills documentation](https://developers.openai.com/codex/skills).
If you prefer a checkout over piping from the network, clone this repository,
`git pull --ff-only` for each update, then run
`bash scripts/install-codex.sh` from the repository root.
To verify installer changes without touching your installed skills, run
`python3 -m unittest discover -s tests -v`. The fixtures exercise local and piped
installs in temporary homes, including updates and competing adapters.
### Cursor Agent
Cursor Agent discovers `~/.codex/skills`, so it uses the **same install and
update command as Codex**:
```bash
curl -fsSL https://raw.githubusercontent.com/skyhook-io/skyhook-skills/main/scripts/install-codex.sh | bash
```
If you already ran that command for Codex, there is nothing else to install.
Start a new Cursor Agent session (or restart Cursor) after an update. Verify under
**Customize → Skills** or invoke `/competitive-research` in Agent chat.
Updating the Cursor binary with `cursor-agent update` is separate and does not
update these skills. See the [Cursor Agent Skills documentation](https://cursor.com/docs/skills).
## The `/qa` seam — bring your own verification
The loops call **`/qa`** to verify a change, but `/qa` is **repo-provided**: each repo defines what verification means there (type-check, tests, and optionally a `/visual-test`). Drop a `.claude/commands/qa.md` in your repo, e.g.:
```markdown
---
description: Verify this change — type-check, tests, and visual-test when a UI change warrants it
---
# QA
- While iterating → a fast tier: only what the change touches (changed packages, `vitest related`, type-check). E.g. a `make test-changed` target.
- Final batch → the full suite once (`make test`, `go test ./...`); CI on the pushed head counts, so don't repeat it locally when CI will run it.
- UI changed → lean toward `/visual-test` for feature-scale rendered changes; skip for small/non-visual. Report status (ran → link the screenshot dir; skipped → why).
```
No `/qa`? The loops fall back to plain build/test detection.
## Prerequisites & optional integrations
- **`/cross-review` reviewers** (pick via `~/.claude/skyhook-skills.json`, `SKYHOOK_REVIEWER`, or a `consult <x>` directive):
- **codex** — needs the official [`codex` plugin](https://github.com/openai/codex-plugin-cc) (`/plugin marketplace add openai/codex-plugin-cc`); defaults to `gpt-6.1-sol`, the latest Sol tier.
- **cursor** — needs the [Cursor CLI](https://cursor.com) (`cursor-agent`) logged in, or `CURSOR_API_KEY` set; defaults to the `gpt-5.6-high` model. For a genuine second opinion when driving from Claude, keep it on a non-Claude model.
- **Default models:** Claude → Codex calls pin `gpt-6.1-sol`; Codex → Claude calls pin `--model opus`, an alias that always resolves to the latest Opus. Codex has no moving alias for Sol, so when a newer Sol ships, bump the id in `commands/cross-review.md`, `commands/codex-review.md`, `commands/plan-loop.md`, and here (`grep -rn gpt-6.1-sol`).
- **Codex → Claude** (the `claude-review` Codex skill) needs the `claude` CLI. On macOS, run it un-sandboxed so it can read Keychain auth, and (if Codex's guardian blocks the export) add a narrow `[auto_review]` allowance in `~/.codex/config.toml`. Long reviews should use streamed JSON and the final `result` field; plain `claude -p` can look idle while it is still reading/thinking.
- **`/review --deep`** uses the [`pr-review-toolkit`](https://github.com/anthropics/claude-plugins-official) plugin if installed (optional).
