# route

A skill that sorts a task or diff into a work domain and hands it to the matching specialist reviewer instead of a generic pass.

## What it does

Five domains cover the routing. Frontend styling and components go to `code-reviewer` with a design and accessibility pass. Public APIs, SDKs, contracts and schemas get contract and back-compat attention. CI, deploy, IaC and migrations go to `k8s-operator`, with blast radius in mind. Markdown and docs alone go to `docs-writer`. Library and business logic stay with `code-reviewer`; when signals mix, the skill falls back to `core`.

A correctness review runs every time, whichever domain wins. Anything touching auth, user input, tenant isolation or secrets also goes to `security-auditor`. Routing adds a targeted pass on top; it drops nothing. Findings come back sorted as Blocking, Should-fix and Nit.

The skill relies on `Read`, `Grep`, `Glob` and `Bash`. Faced with an unclear diff, it leans toward more review, since under-classifying costs more than the extra pass. Nothing is gated: a human still reads and merges. The same repo ships a separate model tiering command, `compass route "<task>"`, which picks a model by cost and checks itself against `scripts/route-evalset.tsv`; domain routing is a different job.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add dshakes/compass --skill route -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/route/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/route/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add dshakes/compass --skill route -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/route/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add dshakes/compass --skill route -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/route/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install dshakes/compass route
```

2. **Manually: put the files in place**
- File: `.github/skills/route/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add dshakes/compass --skill route -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/dshakes/compass --path claude/skills/route
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/route/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add dshakes/compass --skill route -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/dshakes/compass/tree/HEAD/claude/skills/route/SKILL.md

## When to use it
- classify which domain a diff belongs to
- send a task to the right reviewer rather than one broad pass
- add an accessibility check to UI changes
- catch breaking changes in a public API
- audit auth and input changes for security

## Example prompts
- Look at the current diff and tell me which domain it belongs to
- Route this diff to review with a back-compat check on the contract
- Security-check the changes to auth and user input

# Route work to the right specialist

The cloud SDLC classifies each PR (`sdlc-classify.yml`) and runs domain-specific
reviewers. This skill does the same locally: classify, then dispatch.

## Steps
1. **Classify** the task/diff into ONE primary domain (default `core` if mixed):
   | Domain | Signals | Route to |
   |---|---|---|
   | `ui` | frontend, styling, components, UX | `code-reviewer` + a design/a11y pass |
   | `api` | public API/SDK, contracts, schemas | `code-reviewer` + contract/back-compat focus |
   | `infra` | CI, deploy, IaC, migrations | `k8s-operator` / careful review of blast radius |
   | `docs` | docs/markdown only | `docs-writer` |
   | `core` | library / business logic | `code-reviewer` (+ `security-auditor` if it touches authz/inputs) |
2. **Always** run, regardless of domain: a correctness review (`code-reviewer`) and,
   for anything touching auth/inputs/tenancy/secrets, `security-auditor`. Routing only
   *adds* a targeted pass — it never removes the safety-critical ones.
3. **Dispatch**: hand the diff to the chosen subagent(s) in a fresh context; collect and
   summarize findings grouped Blocking / Should-fix / Nit.

## Notes
- Bias to *more* review when uncertain — misclassifying down is the only costly error.
- This is advisory routing; it does not gate anything. The human still reviews and merges.
- **Model tiering** (separate from domain routing): `compass route "<task>"` picks the
  cheapest-correct model (haiku/sonnet/opus). It's **measured** — `compass route --eval`
  scores it against `scripts/route-evalset.tsv` and CI gates on an accuracy floor, so the
  heuristic can't silently regress. Add real mis-routes to the set as they surface.
