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
