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 5.1 | $0.00034 | $0.00421 |
| Opus 5.5 | $0.00014 | $0.00168 |
| Sonnet 5.5 | $0.00007 | $0.00084 |
| Haiku 4.5 | $0.00003 | $0.00042 |
Grade A, and why
node-tools 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.
What it actually says
Node Tools
This is the compiled SKILL.md form of examples/source-only/node-tools.mda.
The MDA-extended top-level fields are relocated under metadata.mda.*, and
the typed footnote is mirrored to metadata.mda.relationships. The output is
acceptable to any agentskills.io v1 consumer.
A consumer that recognizes metadata.mda.requires (§10) can decide
programmatically whether it can satisfy runtime: ["node>=20"],
network: ["api.example.com"], and the tsx / undici packages before
activating the skill.
A relationship
This skill cites the MDA capabilities specification1.

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.

node-tools is a skill published in the GitHub repository sno-ai/mda (621 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 34 tokens to every session and 421 once invoked, about $0.0001 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.
