| description | Token-efficient second opinion slash command /advice. Extracts decision point + artifact (≤150 lines), then fans out in parallel: (1) Opus subagent reviewer with fallback chain codex→agy→cursor, (2) /research on the decision topic, (3) /secondo multi-model opinion. Use instead of advisor() which ships the full conversation uncached. |
/advice — Token-Efficient Second Opinion
Replaces advisor(). Never call advisor() — use this instead.
When invoked
/advice [optional: specific question] — invoked manually or automatically at a decision point.
Step 1: Extract the artifact
From the current conversation, extract:
- Decision (3–5 sentences): what specifically needs a second opinion — be concrete about constraints and tradeoffs
- Artifact (≤150 lines): the relevant code, plan, error, diff, or architecture sketch — nothing unrelated
If no specific question was passed, infer from most recent context. If relevant context exceeds 150 lines, summarize the excess into 2–3 sentences prepended before the artifact.
Step 2: Fan out three reviewers in parallel
Spawn all three in a single message:
Reviewer A — Fallback chain (try in order, stop at first success):
A1 — Opus subagent (primary): Spawn an Agent:
You are a senior engineer giving a focused second opinion.
DECISION:
[decision, 3–5 sentences]
ARTIFACT:
[≤150 lines]
Return exactly:
VERDICT: [recommended approach, one line]
REASONING: [3–4 sentences]
RISK: [main risk, one sentence]
CONFIDENCE: [high / medium / low]
A2 — cursor (fallback if A1 errors):
cursor agent -p --force "Senior engineer second opinion.\n\nDECISION:\n[decision]\n\nARTIFACT:\n[artifact]\n\nReturn VERDICT, REASONING (3-4 sentences), RISK, CONFIDENCE."
A3 — agy (fallback if A2 errors):
agy --print --dangerously-skip-permissions "Senior engineer second opinion.\n\nDECISION:\n[decision]\n\nARTIFACT:\n[artifact]\n\nReturn VERDICT, REASONING (3-4 sentences), RISK, CONFIDENCE."
Note: agy is the Antigravity CLI (reads CLAUDE.md on startup like any CC session, but starts fresh — no current conversation history). Independent perspective, slightly slower than cursor.
A1.1 — claude -p (first-class choice when invoked outside Claude Code; fallback if A3 errors):
claude -p --dangerously-skip-permissions "Senior engineer second opinion.\n\nDECISION:\n[decision]\n\nARTIFACT:\n[artifact]\n\nReturn VERDICT, REASONING (3-4 sentences), RISK, CONFIDENCE."
Note: Same Claude Code context inheritance as agy. For a cleaner isolated call: add --cwd /tmp.
If all options fail, note "Reviewer A unavailable" in the synthesis table.
Reviewer B — Research:
Invoke /research [decision topic distilled to 6 words]
Reviewer C — Secondo:
Invoke /secondo with the decision + artifact (same text as Reviewer A).
Reviewer D — Web Advice:
Invoke /web-advice (runs multi-model Web Chat review via aside-mcp across Gemini Web, ChatGPT, Grok, inspecting PR, evidence bundle, and video proof).
Step 3: Synthesize
Present:
| Reviewer | Verdict | Key concern | Confidence |
|-------------|----------------------|---------------------|------------|
| A (source) | ... | ... | high/med/low |
| Research | [consensus finding] | [main caveat] | — |
| Secondo | ... | ... | — |
| Web Advice | ... | ... | — |
- 2+ agree → state recommended path, proceed
- All three diverge → surface disagreement, ask user which axis matters most (speed / safety / cost)
Final verdict format — binary, SHA-bound (mandatory)
When /advice is being run as the gate in the draft-first-pr lifecycle (~/.claude/skills/draft-first-pr/SKILL.md), the synthesis MUST end with exactly one binary line, bound to the commit SHA reviewed:
VERDICT: APPROVED at <SHA>
or
VERDICT: NOT APPROVED at <SHA>
<SHA> is the PR's current HEAD SHA at the moment of review (gh pr view <N> --json headRefOid --jq '.headRefOid' if reviewing a PR; the working-tree commit SHA otherwise). This verdict is valid only for that exact SHA — per the SHA-binding rule in draft-first-pr/SKILL.md, a new commit invalidates it and /advice must be re-run at the new SHA before the PR can be marked ready. Do not emit a bare "APPROVED"/"looks good" without the SHA — an unbound verdict cannot be checked for staleness later.
Token budget
| Reviewer | Tokens sent |
|---|
| Reviewer A | Decision + artifact ≈ 1,500–2,500 tokens |
| /research | Web queries only |
| /secondo | Decision + artifact ≈ 1,500–2,500 tokens |
| Total | ~5,000 tokens vs ~80,000–140,000 for advisor() |
96–97% fewer input tokens per review cycle.
Fallback chain summary
| Priority | CLI | When |
|---|
| A1 | Claude subagent (Opus) | Primary (inside Claude Code) |
| A1.1 | claude -p --dangerously-skip-permissions | First-class choice when invoked outside Claude Code; fallback if A3/agy errors |
| A2 | cursor agent -p --force | Opus unavailable |
| A3 | agy --print --dangerously-skip-permissions | cursor errors |
