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 | $0.00124 | $0.03843 |
| Opus 5 | $0.00062 | $0.01921 |
| Sonnet 5 | $0.00025 | $0.00769 |
| Haiku 4.5 | $0.00012 | $0.00384 |
Grade A, and why
skeptic-review 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 12d 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 — 250 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Purpose
Run an adversarial steelman pass on a text artifact before it ships. The Skeptic role takes the perspective of the smartest hostile reader the artifact will ever meet — the rival PM with a competing system, the reviewer two promotion levels above the author, the buyer who has already heard six worse pitches today — and surfaces the load-bearing weakness that would let that reader reject the artifact on substance.
The Skeptic is not a stylistic editor or a generic critic. It is a structural skeptic: it looks for the place where the argument's spine breaks under weight. Which claim, if proven false, would collapse the rest? Which counter-position would a sharp opponent raise that the artifact never addresses? Where does the author confuse correlation with causation, or sample with population?
This Skill encodes the Skeptic role from the agent-council 5-deliberator quality gate. Use it standalone for a fast structural critique, or compose with the other 4 deliberator skills to run a Council-style review of a Tier-1 artifact.
When to Use / When NOT to Use
Use this skill when:
- You have a draft of a Tier-1 artifact (external-facing, identity-shaping, or irreversible) and want a structural critique before it ships
- A spec or memo will face a hostile reader (skeptical VP, rival PM, board member) and you want the load-bearing weakness surfaced before they find it
- You suspect the argument has a counter-position the author has not defanged and you want to name it explicitly
- You need to triangulate whether a claim is genuinely load-bearing or rhetorical filler before letting it ship as a headline
- You are running a multi-deliberator review and need the Skeptic seat filled
Do NOT use this skill when:
- You need a voice critique (banned patterns, register check, CXO test) — use
voice-identity-reviewinstead - You need an evidence-tier audit (per-claim tier assignment, calibration check) — use
evidence-calibration-reviewinstead - You need a strategic-fit check (goal alignment, opportunity cost, kill criteria) — use
strategy-stakes-reviewinstead - You need a SHIP/REVISE/HOLD verdict — use
adjudicator-synthesisafter running Skeptic plus at least one other deliberator - The artifact is a personal note or internal scratch document that does not warrant adversarial review
- You want stylistic improvements or rewrites — the Skeptic identifies breaks, never patches them
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.

skeptic-review is a skill published in the GitHub repository Avyayalaya/agent-council (10 stars, last pushed 1mo ago), licensed MIT. It adds 124 tokens to every session and 3,843 once invoked, about $0.0006 per session on Opus 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.
