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.

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 | $0.00052 | $0.00776 |
| Opus 5 | $0.00026 | $0.00388 |
| Sonnet 5 | $0.00010 | $0.00155 |
| Haiku 4.5 | $0.00005 | $0.00078 |
Grade A, and why
cheatsheet-duplication-checker 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 2d 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.

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.

cheatsheet-duplication-checker is an agent published in the GitHub repository OWASP/CheatSheetSeries (33,037 stars, last pushed today), licensed CC-BY-SA-4.0. It adds 52 tokens to every session and 776 once invoked, about $0.0003 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.
Other agents, from other repositories
appsec-threat-renderer
INTERNAL renderer for Stage 2 of create-threat-model. Invoke only from the skill after Stage 1 has produced validated intermediate artifacts.
appsec-triage-validator
INTERNAL — controller-dispatched cross-component threat triage; validates rating consistency and prioritization, writes .triage-flags.json, and annotates .threats-merged.json.
appsec-trust-boundary-analyst
INTERNAL — dedicated Stage-1b analyst. Assesses deterministic crossing signals in a fresh context and writes only untrusted trust-boundary candidates and explicit signal dispositions.
appsec-actor-discoverer
INTERNAL — controller-dispatched actor discovery after config/IaC scanning and before architecture modeling; writes .actors-discovered.json and is skipped in quick mode.
appsec-fragment-fixer
INTERNAL — lightweight repair executor for the create-threat-model re-render loop; rewrites only planned fragments and reruns deterministic composition without analysis stages.
appsec-reviewer
Security reviewer for a single code change. Reads the diff, works out which security expectations it implicates, and grades the post-change code PASS/PARTIAL/FAIL/UNVERIFIABLE/NOTAPPLICABLE with file:line evidence and a code-aware fix → .requirements-verification.json. Grades against the active standard: the company…
