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.

SkillSpector: 1 finding, 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 →
- medium Excessive Agency · line 203 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00037 | $0.01342 |
| Opus 5 | $0.00018 | $0.00671 |
| Sonnet 5 | $0.00007 | $0.00268 |
| Haiku 4.5 | $0.00004 | $0.00134 |
Grade A, and why
codeql-security-scanner 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 10d 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 — 213 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CodeQL Security Scanner
Trigger / When to Use
Use this skill when the user wants deep semantic code scanning, GitHub Advanced Security style analysis, custom CodeQL queries, SARIF output, or vulnerability investigation with CodeQL databases.
Good trigger phrases:
- "run CodeQL locally"
- "add CodeQL code scanning"
- "scan JavaScript for security issues"
- "write a CodeQL query"
- "upload SARIF to GitHub"
- "investigate a CodeQL alert"
Core Capabilities
- Build CodeQL databases for supported languages.
- Run default and security-extended query suites.
- Produce SARIF reports for GitHub code scanning.
- Investigate dataflow-based vulnerabilities.
- Author and test custom queries for recurring insecure patterns.
- Integrate scans in GitHub Actions or local CI.
Workflow
1. Identify Languages
Inspect the repository:
rg --files | sed -n '1,160p'
Determine:
- Primary language.
- Build command.
- Whether generated code should be excluded.
- Whether dependencies need to be installed before database creation.
- Whether multiple CodeQL databases are required for a polyglot repo.
2. Verify CodeQL CLI
codeql version
If missing, use official GitHub CodeQL CLI installation guidance. For GitHub-hosted workflows, prefer github/codeql-action.
3. Create a Database
For compiled languages, provide the real build command:
codeql database create codeql-db --language=java --command="mvn -DskipTests package"
For JavaScript or TypeScript:
codeql database create codeql-db --language=javascript-typescript
For Python:
codeql database create codeql-db --language=python
If database creation fails, fix dependency installation or build steps before analyzing.
4. Run Queries
Default query suite:
codeql database analyze codeql-db --format=sarif-latest --output=codeql.sarif
Security extended suite:
codeql database analyze codeql-db codeql/javascript-queries:codeql-suites/javascript-security-extended.qls --format=sarif-latest --output=codeql.sarif
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.

codeql-security-scanner is a skill published in the GitHub repository seaworld008/Commonly-used-high-value-skills (70 stars, last pushed 2d ago), licensed MIT. It adds 37 tokens to every session and 1,342 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 2026-08-30.
