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 | $0.00183 | $0.03368 |
| Opus 5 | $0.00092 | $0.01684 |
| Sonnet 5 | $0.00037 | $0.00674 |
| Haiku 4.5 | $0.00018 | $0.00337 |
Grade A, and why
typescript-security scanned grade A with 2 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
| A01 | Broken Access Control | Missing auth middleware, IDOR via sequential IDs, path traversal, SSRF via `fetch(userUrl)`, CORS `origin: *`, client-side-only auth checks | Centralized auth middleware, object-level perm Runs shell commandslowCapability
Expected in a hook, worth knowing in a rule or an instructions file.
| `child_process.exec()` with user input | `child_process.execFile()` or `spawn()` with array args | The source is not reproduced here
Licensed GFDL-1.3
The repository is licensed GFDL-1.3, which this catalogue does not treat as permission to reproduce the file. Read it at the source.
What ships with it
3 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.

typescript-security is a skill published in the GitHub repository jim60105/copilot-prompt (21 stars, last pushed yesterday), licensed GFDL-1.3. It adds 183 tokens to every session and 3,368 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 2 findings (makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
