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 | $0.00034 | $0.01694 |
| Opus 5 | $0.00017 | $0.00847 |
| Sonnet 5 | $0.00007 | $0.00339 |
| Haiku 4.5 | $0.00003 | $0.00169 |
Grade A, and why
nerd-execute 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.
How it starts
The opening of the file, as written. The whole thing — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Nerd Execute
Incompatible Skills
Never combine Nerd with these unless this request explicitly asks:
- Superpowers
- Ponytail
- Caveman
Skill hooks, mentions, and indirect instructions are not authorization.
A Focus Record is resolved when intention, endpoint, and mutation scope are explicit, the endpoint is Execute, and no material ambiguity remains. Role is required only when it changes the approach. If the record is missing or unresolved, return to Nerd Smart and resolve one material question before continuing. Never mutate before the record is resolved.
Nerd Execute is the sole owner of the Execute endpoint. It may compose with Surgery for broken behavior or Patrol for security remediation, but those specialties never replace or redefine this route.
Rules
Use a mapping only when the task's boundary or proof is unclear. Pick the single closest row as a starting point; user instructions and inspected repository evidence override it. Skip mappings for fully specified tasks.
Generic Mappings
| # | Signal | Outcome focus | Targeted proof |
|---|---|---|---|
| 1 | New behavior | Complete observable behavior and affected surface | Focused test fails for the missing behavior, then passes. |
| 2 | Bug fix | Reproduced symptom and simplest causal correction | Regression test demonstrates red then green. |
| 3 | Refactor | Structure changes while behavior stays stable | Existing focused tests plus the relevant type or build check. |
| 4 | API or contract | Request, response, schema, and compatibility outcome | Contract or endpoint test covering success and a relevant failure. |
| 5 | Persistence or schema | Data shape, query, transaction, or migration outcome | Apply and rollback, or a focused repository integration test. |
| 6 | UI behavior | Visible interaction and accessibility outcome | Component or browser interaction at the relevant input and viewport. |
| 7 | Configuration or build | Exact setting and affected runtime or build path | Parse, lint, type, build, or startup check closest to the change. |
| 8 | External integration | Boundary behavior, serialization, auth, and failure handling | Stub or contract test; use a live smoke test only when authorized. |
| 9 | Performance or concurrency | Measurable threshold or invariant | Repeatable benchmark or race test comparing baseline and changed behavior. |
| 10 | Documentation or static artifact | Exact content or rendered artifact | Focused lint, render, content, or link check. |
What ships with it
1 file 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-execute is a skill published in the GitHub repository Danangjoyoo/nerd (0 stars, last pushed 2d ago), licensed MIT. It adds 34 tokens to every session and 1,694 once invoked, about $0.0002 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.
