skeptical-triage

skeptical-triage is a skill for Claude Code from avelikiy/great_cto. It costs 49 tokens per session (2,214 once invoked), scanned A, original, MIT.

A review method that challenges an important finding through three rounds of skeptical checking and then asks an arbiter to judge the result. It is designed to separate real problems from false alarms.

In plain words
What is it for?
Use it to reassess serious review findings, security alerts, flaky-test verdicts, regressions, and disputes between architecture options.
Why use it?
It reduces the chance that an incorrect security, QA, regression, or architecture finding blocks work or leads to unnecessary changes.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

skeptical-triage 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 8d 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.

Skeptical Triage

Filter false positives from multi-angle review, security audit, QA regression flags, or any high-stakes judgment before it turns into a blocker.

Three rounds of skeptical self-review + an impartial arbiter, with a confidence score from the vote.

When to invoke

Caller Finding type Apply triage?
/review Angle 2/4/7/9 P0/P1 (security, SQL, privacy, concurrency) Yes
/review --deep Any angle P0/P1 Yes
security-officer CSO audit P0/P1 Yes
security-officer Secret in source/git, confirmed CVE No — hard finding
qa-engineer Flaky-test verdict (is this a regression or flake?) Yes
architect ADR trade-off dispute (option A vs. B when both look reasonable) Yes
Any P2/advisory No

The 4-step pattern

Run these sequentially. Each round sees prior reasoning. Arbiter sees all rounds.

Round 1 — Reachability / Premise

Question: is the premise true?

  • For security/reliability: can an external attacker reach this code path with untrusted input? Trace input flow backward from the bug site to its origin. If only trusted internal callers → lean INVALID.
  • For regressions: does the failing behavior reproduce from a clean state on the target branch?
  • For ADR trade-offs: is the constraint that forces the choice actually binding? (e.g. "we need <10ms p99" — is that real or aspirational?)

Output: {round: 1, verdict: VALID|INVALID|UNCERTAIN, reasoning: "...", crux: "single key fact"}

Round 2 — Verify cited defenses / counter-evidence

Question: are claimed defenses real and sufficient?

  • Every cited defense → use Grep to find its actual implementation line.
  • Resolve constant names to numeric values. MAX_BUF_SIZE is not a verified bound — #define MAX_BUF_SIZE 64 is.
  • For regressions: is the cited "test covers this" actually asserting the right invariant?
  • For ADR: is the cited benchmark/precedent real (grep for it, read it), or rumored?

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.

skeptical-triage is a skill published in the GitHub repository avelikiy/great_cto (92 stars, last pushed yesterday), licensed MIT. It adds 49 tokens to every session and 2,214 once invoked, about $0.0002 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 2026-09-03.
