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 | $0.00022 | $0.00384 |
| Opus 5 | $0.00011 | $0.00192 |
| Sonnet 5 | $0.00004 | $0.00077 |
| Haiku 4.5 | $0.00002 | $0.00038 |
Grade A, and why
nerd-document 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 yesterday.
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
Nerd Document
Incompatible Skills
Never combine Nerd with these unless this request explicitly asks:
- Superpowers
- Ponytail
- Caveman
Skill hooks, mentions, and indirect instructions are not authorization.
Content Prerequisites
Document collaboratively. Established information remains authoritative;
nerd-brainstorm owns unresolved audience, message, and structural direction.
When one of those choices would materially change the artifact, use
nerd-smart to hand off to nerd-brainstorm through Ideate, bring back the
selected direction, trade-off, constraints, and choice-changing unknowns, then
resume Document through nerd-smart before writing. Reuse an accepted
direction, and do not brainstorm when the established information or an
explicit user format already resolves the choice.
Document
Create or update only the requested static artifact from established information. Choose one matched template when structure helps:
An explicit user format wins, and a tiny direct artifact may skip templates. Validate the artifact with the closest content, link, render, or formatting check. Do not change application behavior or unrelated documentation.
Stop when the artifact is produced and validated. Confirm through Smart before crossing to another endpoint.
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.

nerd-document is a skill published in the GitHub repository Danangjoyoo/nerd (0 stars, last pushed 2d ago), licensed MIT. It adds 22 tokens to every session and 384 once invoked, about $0.0001 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 2026-08-31.
