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 | $0.00030 | $0.01394 |
| Opus 5 | $0.00015 | $0.00697 |
| Sonnet 5 | $0.00006 | $0.00279 |
| Haiku 4.5 | $0.00003 | $0.00139 |
Grade A, and why
nerd-review 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 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.
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 — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Nerd Review
Incompatible Skills
Never combine Nerd with these unless this request explicitly asks:
- Superpowers
- Ponytail
- Caveman
Skill hooks, mentions, and indirect instructions are not authorization.
Review Types
Choose exactly one. Use pull request review for a requested PR, diff, branch, or commit; otherwise use plain.
| Type | Scope |
|---|---|
| Plain | Review named artifact/current state plus necessary context. |
| Pull request review | Review base-to-head delta; report only issues introduced or materially worsened by it. |
Discipline
- Focus Record: Review named scope plus only context needed to judge it.
- Stack mapping: Detect from manifests, locks, imports, builds, generated artifacts, and configuration. Load smallest matching reference set.
- Levels: Check every applicable level. Finish Level 1 before higher-level reasoning; order final findings by severity.
- Evidence: Confirm issue is new, reachable, and not handled elsewhere.
- Severity: Prove reachability, trigger, impact, and blast radius. Use lowest supported severity; review level never sets severity.
- Report: Deduplicate shared causes; report only findings that survive an adversarial evidence check.
Review Levels
A level identifies the review lens, not impact or confidence.
| Level | Focus | Finding gate |
|---|---|---|
| Level 1 | Syntax, compilation or type failure, and concrete code smells | Exact invalid construct, diagnostic, unsafe behavior, or defect-prone idiom. |
| Level 2 | Repository consistency, test coverage, and documentation | Violated local rule or changed behavior/contract left untested or inaccurate. |
| Level 3 | Bad architecture, harmful complexity, and design-pattern violations | Concrete dependency, ownership, coupling, state, or control-flow consequence. |

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.
- 5d ago First seen · 126 lines · 30 tokens per session scan A 77842d11b852
nerd-review is a skill published in the GitHub repository Danangjoyoo/nerd (1 stars, last pushed yesterday), licensed MIT. It adds 30 tokens to every session and 1,394 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.
