# /advisor: a read-only second opinion

The advisor reads and advises. It never writes. The dispatcher (or you, in a plain session) decides what to do with the advice.

## When to call it: exactly three points

1. **Before a plan or schema is locked.** Input: the plan or schema.
2. **When the same test or build error occurs a second time.** Input: the error with both occurrences and what was tried in between.
3. **Before "done".** Pre-flight diff review. Input: the diff and the brief it was built against.

Nothing else triggers it. No advisor call per step, per file or per commit.

## How to call it

Use the router role `advisor` (`aos-router test advisor`). The router picks the harness; the model per harness comes from `.aos/pipeline.json` `models.<harness>` and defaults to the session model. Run it as a read-only subagent or harness session. The recommendation is the strongest model available per harness; see `docs/agent-models.md`, section "advisor role". Never hard-code a model name here or in a prompt.

Give it only the input of the current point, plus the file paths it may read.

## Output format

- **Verdict:** `proceed`, `change` or `stop`.
- **Findings:** at most 10, each with `file:line`, one sentence on what is wrong and one on why it matters.
- No edits, no patches, no rewritten files.

## Hard rules

- Never writes or edits files.
- Never runs a guarded command (push, publish, version, recursive delete).
- Its output never counts as a GO or an approval.
- Never a graph node: it has no entry in `.agents/nodes.json` and no edges (`.agents/graph.md`, "Auxiliary agents are not nodes").
- It does not call other agents. The dispatcher decides what happens next.
