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 high
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 →
- high Privilege Escalation · line 110 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
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 | $0.00009 | $0.03046 |
| Opus 5.5 | $0.00004 | $0.01218 |
| Sonnet 5.5 | $0.00002 | $0.00609 |
| Haiku 4.5 | $0.00001 | $0.00305 |
Grade A, and why
deno-knowledge-patch 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.
How it starts
The opening of the file, as written. The whole thing — 226 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Deno Knowledge Patch
Use this skill when choosing current Deno runtime APIs, CLI options, configuration, dependency behavior, Node compatibility, or deployment workflows. Open the topic reference before changing a project because several commands, flags, APIs, and defaults changed more than once.
Working approach
- Inspect
deno --version,deno.jsonordeno.jsonc,package.json,deno.lock, workspace files, and CI commands. - Read every reference relevant to the requested change; later version-attributed guidance supersedes earlier behavior only where it explicitly changes it.
- Preserve least-privilege permissions. Do not add
-Amerely to silence a permission failure. - Keep manifest and lockfile changes together, and prefer frozen installation modes in CI.
- Treat the project's manifests, code, tests, and observed behavior as authoritative when they conflict with general guidance.
- Verify with the narrowest applicable built-ins:
deno check,deno lint,deno fmt --check,deno test, and the requested build or package command.

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.

deno-knowledge-patch is a skill published in the GitHub repository Nevaberry/nevaberry-plugins (24 stars, last pushed 1mo ago), licensed MIT. It adds 9 tokens to every session and 3,046 once invoked, about $0.0000 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 2026-08-30.
