Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00116 | $0.01128 |
| Opus 5.5 | $0.00046 | $0.00451 |
| Sonnet 5.5 | $0.00023 | $0.00226 |
| Haiku 4.5 | $0.00012 | $0.00113 |
Grade A, and why
second-opinion scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Second opinion: independent review before presenting
Before presenting non-trivial thinking to the user, get an independent review of it. A second opinion is what a second doctor does: look at the situation fresh, form an independent view, say where they agree and where they'd do differently. The output is for you. The user sees the result of your improved reasoning, not the raw review.
What a valid second opinion is
Bind to the strongest channel available in this session that satisfies all three properties. The properties are fixed; the mechanism is whatever best provides them.
- Independent: produced by something that didn't do the work and isn't anchored on your reasoning. Self-review wearing a reviewer hat is not a second opinion.
- Fully informed: sees as much of the real context as possible. Prefer a channel that reads the full transcript over one you hand a summary: a distillation is curated by the same mind being reviewed, so your blind spots survive it. Distill only when the channel can't take the whole context.
- At least peer-strength: a weaker model reviewing a stronger one mostly generates noise. Match or exceed your own capability.
Choosing the channel
In rough order of preference:
- A dedicated reviewer/advisor tool the harness exposes that sees the full transcript: best on the "fully informed" axis, no distillation loss.
- Fresh-context subagents at peer strength, given a faithful distillation, when no full-transcript channel exists. Spawn more than one for high-stakes or genuinely multi-faceted decisions; run them in parallel when the host supports it. Their convergence or divergence is itself signal.
- No independent channel available: say so plainly and fall back to a structured self-critique, labeled as such. A self-review honestly named beats one dressed up as independent. Don't simulate a second opinion that isn't there.
Let the stakes drive depth (a quick sanity check versus a full adversarial pass), not a fixed reviewer count.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

second-opinion is a skill published in the GitHub repository pandysp/claude-plugins (6 stars, last pushed 7d ago), licensed MIT. It adds 116 tokens to every session and 1,128 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
