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 | $0.00037 | $0.00632 |
| Opus 5.5 | $0.00015 | $0.00253 |
| Sonnet 5.5 | $0.00007 | $0.00126 |
| Haiku 4.5 | $0.00004 | $0.00063 |
Grade A, and why
nerd-explore 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 2mo 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 — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Nerd Explore
Incompatible Skills
Never combine Nerd with these unless this request explicitly asks:
- Superpowers
- Ponytail
- Caveman
Skill hooks, mentions, and indirect instructions are not authorization.
Focus Record
Explore owns its own record. Resolve it from the request before the first read, and keep it — with all working notes — in context only, never as a maintained ledger or emitted report:
Focus Record
- Question: [Fact, pattern, constraint, or unknown to resolve]
- Boundary: [Paths, symbols, or artifacts in scope]
- Keep one active question and one smallest useful next read.
- Attach a path, symbol, line, or command result to each confirmed fact.
- Hold confirmed facts, hypotheses, and unknowns in context; update them after each read.
Fast Discipline
- Speed belongs to discovery only. Never load
nerd-fastornerd-xfast, and never alter the caller's analysis depth, proof, or reporting rigor. - Batch reads that are already known and independent into one operation; keep a read sequential whenever its result can change the next one.
- Estimate the total lines a direct path would require before the first read. Below roughly 200, read or search the targets directly; above it, navigate by symbol or keyword search instead of whole-file reads.
- Never trade accuracy for latency. Facts leave Explore as the caller's input, so a lossy shortcut here is invisible downstream.
Exploration Loop
- Start direct
- Open the exact file, path, symbol, error, or artifact named by the user first.
- Read the relevant region or outline before reading the whole file.
- Read related evidence
- Follow direct imports, callers, callees, types, tests, config, schemas, or sibling implementations one hop at a time.
- Prefer targeted keyword/symbol searches and narrow line ranges.
- Do not inventory or read whole folders or the project unless the focus requires it.
- Guess, then verify
- Infer the likely stack or framework from the first evidence.
- Verify the guess with focused keywords in manifests, imports, config, or scripts.
- Keep guesses labeled as hypotheses until verified.
- Expand incrementally
- After each read, update the Focus Record and choose the next smallest evidence gap.
- Expand only when current evidence cannot answer the active question.
- Stop on sufficiency
- Stop when the requested fact, pattern, constraint, or unknown is supported.
- Answer the active question directly with exact sources; no report or ledger template.
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-explore is a skill published in the GitHub repository Danangjoyoo/nerd (1 stars, last pushed 12d ago), licensed MIT. It adds 37 tokens to every session and 632 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 2026-08-31.
