SkillSpector: 10 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00101 | $0.10802 |
| Opus 5 | $0.00051 | $0.05401 |
| Sonnet 5 | $0.00020 | $0.02160 |
| Haiku 4.5 | $0.00010 | $0.01080 |
Grade A, and why
writing-slicc-tests 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 5d 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 — 1,009 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Set Up the Framework
- Framework: Vitest with
globals: true,environment: node - Convention:
foo.test.tsinpackages/*/tests/mirroring thesrc/structure - Import fake-indexeddb when VirtualFS is used:
import 'fake-indexeddb/auto'
Note: npm run test runs the default Node-mode Vitest projects only. It does
not include:
- Browser-mode suites:
npm test -w @slicc/webcomponentsandnpm test -w @ai-ecoverse/spoon(real Chromium via@vitest/browser) - Server integration:
npm run test:server-integration - Playwright E2E:
npm run test:e2e
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.

writing-slicc-tests is a skill published in the GitHub repository ai-ecoverse/slicc (30 stars, last pushed today), licensed Apache-2.0. It adds 101 tokens to every session and 10,802 once invoked, about $0.0005 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 2026-09-05.
