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 | $0.00038 | $0.00808 |
| Opus 5.5 | $0.00015 | $0.00323 |
| Sonnet 5.5 | $0.00008 | $0.00162 |
| Haiku 4.5 | $0.00004 | $0.00081 |
Grade A, and why
codebase-research 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.
How it starts
The opening of the file, as written. The whole thing — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Purpose
Shared policy: Follow
instructions/coordination.instructions.mdfor precedence, invocation, delegation, and handoffs. Applyinstructions/workflow.instructions.mdfor proportional work and verification.
You are investigating what already exists so later design work is grounded in the actual project rather than assumptions.
Your goals are to:
- Map the codebase — understand directory layout, key configuration, and entry points.
- Identify patterns — capture frameworks, architecture style, naming conventions, and test approach.
- Find relevant code — locate modules, services, components, or tests connected to the requested feature area.
- Document constraints — note dependencies, tech debt, abstractions, and project-specific instructions that later phases must respect.
When to use this skill
Use this skill whenever:
- A feature idea needs research before design decisions are made.
- The user asks to investigate, explore, summarize, or understand a codebase area.
- A later
feature-design-docshould be grounded in real project structure, patterns, and constraints. - You need the first atomic step in the chain:
codebase-research→feature-design-doc→task-breakdown→implementation-runner.
Do not use this skill for:
- Design work — use
feature-design-doc. - Task generation — use
task-breakdown. - Implementation — use
implementation-runner. - End-to-end gated planning and implementation — recommend
prd-workflowinstead of nesting it.
Workflow
Before designing anything, understand what exists.
- Discover project structure — read directory layout, key config files, entry points.
- Identify existing patterns — frameworks, architecture style, naming conventions, test approach.
- Find relevant code — modules, services, or components related to the feature area.
- Note constraints — dependencies, tech debt, existing abstractions that must be reused.
- Check project config — if
.github/instructions/project-config.instructions.mdexists, read it for framework, infra, and tooling choices.
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.

codebase-research is a skill published in the GitHub repository NickPolyder/NP.CoPilot.Config (2 stars, last pushed 1mo ago), licensed MIT. It adds 38 tokens to every session and 808 once invoked, about $0.0002 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.
