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 | $0.00122 | $0.00969 |
| Opus 5.5 | $0.00049 | $0.00388 |
| Sonnet 5.5 | $0.00024 | $0.00194 |
| Haiku 4.5 | $0.00012 | $0.00097 |
Grade A, and why
codeql 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 1mo 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.

The opening of the file, as written. The whole thing — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CodeQL for .NET
Trigger On
- the repo uses or wants CodeQL for .NET security analysis
- GitHub code scanning is part of the CI plan
Value
- produce a concrete project delta: code, docs, config, tests, CI, or review artifact
- reduce ambiguity through explicit planning, verification, and final validation skills
- leave reusable project context so future tasks are faster and safer
Do Not Use For
- teams that need a tool with no private-repo licensing caveat
Inputs
- the nearest
AGENTS.md - hosting model: open-source repo, private repo, or manual CLI workflow
- current GitHub Actions workflow
Quick Start
- Read the nearest
AGENTS.mdand confirm scope and constraints. - Run this skill's
Workflowthrough theRalph Loopuntil outcomes are acceptable. - Return the
Required Result Formatwith concrete artifacts and verification evidence.
Workflow
- Treat CodeQL as a security-analysis tool, not as a style checker.
- Make the licensing and hosting model explicit before proposing it as the default gate.
- Prefer manual build mode for compiled .NET projects when precision matters.
Bootstrap When Missing
If CodeQL is not configured yet:
- Detect current state:
rg -n "codeql-action|security-events|CodeQL" .github/workflowscommand -v codeql
- Prefer CI-first setup for repository scanning using
github/codeql-action/initandgithub/codeql-action/analyze. - Configure explicit .NET build mode in workflow (
manualwhen precision matters). - Add local CLI usage only when the task requires local query work.
- Run the workflow or local analyze path and return
status: configuredorstatus: improved. - If licensing or hosting constraints reject CodeQL for this repo, return
status: not_applicablewith caveat documented.
Deliver
- explicit CodeQL setup or an explicit rejection with caveat documented
- reproducible CI or local commands for running CodeQL in this repo
Validate
- the chosen CodeQL path is allowed for the repo type
- build mode is documented and reproducible
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 1mo ago First seen · 103 lines · 122 tokens per session scan A 0a6315d684d8
codeql is a skill published in the GitHub repository managedcode/dotnet-skills (495 stars, last pushed yesterday), licensed MIT. It adds 122 tokens to every session and 969 once invoked, about $0.0005 per session on Opus 5.5. 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.
