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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00049 | $0.02214 |
| Opus 5 | $0.00024 | $0.01107 |
| Sonnet 5 | $0.00010 | $0.00443 |
| Haiku 4.5 | $0.00005 | $0.00221 |
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.
How it starts
The opening of the file, as written. The whole thing — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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
Grepto find its actual implementation line. - Resolve constant names to numeric values.
MAX_BUF_SIZEis not a verified bound —#define MAX_BUF_SIZE 64is. - 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?
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.

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.
Other skills, from other repositories
audit
Project health audit and health check — architecture, performance, tests, dependencies, code quality. Use when assessing overall project health, before releases, or after refactors.
review-all
Multi-agent code review for diffs (project-agnostic). Covers standards, bugs, security, DRY, smells, perf, tests, API contracts, a11y/i18n. Verifies each finding to eliminate false positives. Use for /review-all, pre-PR/pre-commit review, or auditing uncommitted/staged changes.
rubber-ducky
Use when you've planned a non-trivial change and are about to implement it, finished a complex or multi-file piece of work, just wrote tests, or are stuck on repeated failures — and any time the user says "rubber duck this", "rubber ducky", "get a second opinion", "sanity-check my plan", "poke holes in this", "what am…
mobile-flows-maestro
This skill should be used when Maestro is explicitly requested or already present and the task is to author, run, or debug iOS/Android Maestro flows; use Maestro MCP; or handle Maestro selectors, system UI, permissions, Keychain, JavaScript, waits, device state, flakiness, or CI. Evidence includes a .maestro directory…
fec-debug-framework
A step-by-step method for finding the cause of front-end build failures, browser errors, broken screens, failed requests, or incorrect data. It separates build, runtime, visual, and API problems and uses evidence to test possible causes.
fec-legacy-to-modern-migration
A guide for moving older front-end code—such as JavaScript, jQuery, HTML/CSS, server-rendered pages, or old frameworks—to newer tools while keeping the same behavior. It covers gradual migrations as well as modernising parts of a multi-page site.
