## What it does

The skill introduces a mandatory scope check before any coding action. In a single turn, the agent states a target hypothesis with a 0 to 100% confidence rating and tracks repository assumptions as verified, assumed, or contradicted. It gathers project facts independently through searches and file reads, withholding sensitive credentials behind placeholders like `<API_TOKEN>`.

Requests get sorted into three distinct paths. Route A bypasses design documents for localized, deterministic bug fixes and mechanical refactors. Route B creates a 5 to 10 line spec whenever large migrations or single compatibility issues arise. For architectural updates or vague requirements, Route C enforces a hard stop that forbids code creation until the design is drafted and approved.

Non-interactive environments like autonomous agents or CI cannot run Route C. If ambiguity appears without a human operator present, the execution halts immediately rather than risking blind guesses.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add sentimony/skills --skill scope-triage -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add sentimony/skills --skill scope-triage -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add sentimony/skills --skill scope-triage -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install sentimony/skills scope-triage
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add sentimony/skills --skill scope-triage -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/sentimony/skills --path plugins/devflow/skills/scope-triage
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add sentimony/skills --skill scope-triage -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/sentimony/skills/tree/HEAD/plugins/devflow/skills/scope-triage/SKILL.md

## When to use it
- Prevent premature coding when architectural requirements remain vague
- Skip unnecessary specification cycles on localized and mechanical fixes
- Document assumptions and track verified facts across project files
- Guard secrets and auth tokens against leaking into prompt history

## Example prompts
- Review the scope for migrating session storage: design this properly
- Fix the off-by-one error in pagination, done criterion is clear, skip design
- Run scope triage on adding multi-tenant workspace routing

# Scope Triage Before Design

Turn a request into either an implementation contract or a fully formed design. Classification comes
first, always: one turn that states a hypothesis, records assumptions, and picks a route. Only Route C
runs the full design cycle; A and B exist so an already-specified change is not taxed with a design.

## Step 0 - Scope Check

Do this before any other action, in a single turn, for every request.

1. **Hypothesis with confidence.** One sentence naming what the user wants to end up with, plus an
   honest 0-100% confidence. Below 70%, add one line stating what is missing.
2. **Assumption ledger.** List the assumptions the answer rests on; mark each `verified` (confirmed in
   code or docs this session), `assumed`, or `contradicted` (checked and found false). Retrieve
   repository facts yourself: one broad fan-out search aimed at the unverified ledger rows first, then
   targeted reads of the contract files the design depends on; ask only user decisions. Any
   `contradicted` entry means Route C.
3. **Classify** against the route conditions below.
4. **Announce the route** in one self-contained sentence: it must repeat the target contract in full,
   carrying the domain values the request states, and read correctly on its own.

   Never reproduce a secret, token, key, password, connection string, or personal datum -
   not in this sentence, not anywhere else in the workflow. Refer to such an input by
   placeholder name (`<API_TOKEN>`) and state that the value is withheld. Domain values are
   the safe remainder: paths, symbols, counts, the numbers from a bug report.

**Route C (full design) - if ANY of these hold:**

- requirements are ambiguous or contradictory;
- the user-visible outcome or the success criteria are still undefined;
- there is a product, UX, or visual decision to make;
- two or more materially different architectural approaches exist;
- the change creates a new capability or public contract, or materially alters data flow;
- you would have to pick a behavior the user never specified;
- an `assumed` entry about product, UX, or a public contract is still unverified;
- you cannot predict the user's answers to the next three questions you would ask.

**Route A (direct implementation) - only if ALL of these hold:**

- the user stated the target outcome explicitly;
```
