codebase-map from jackispm/nausicaa-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add jackispm/nausicaa-harness/codebase-map@git:20260907.7726f1aPins git:20260907.7726f1a in mdr.lock. Pin the fingerprint instead.

Investigate a codebase or subsystem and return a concise, evidence-backed map of its purpose, entry points, contracts, and relevant tests.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Codebase Map Quickly investigate the requested codebase or subsystem and return structured findings that another person or agent can use without rereading everything. Use read-only inspection; this Skill does not authorize changes. Infer the depth from the task: targeted lookups for a quick question, imports and critical sections for a normal investigation, dependencies and tests for a thorough audit. Do not expand a narrow request into a whole-repository survey. 1. Locate entry points and relevant code with the available file-search tools. 2. Read key sections and their actual callers. Use the README as an orientation, then verify claims against source and configuration. 3. Identify important types, interfaces, functions, and ownership boundaries. 4. Follow dependencies far enough to explain how the requested behavior works. 5. Identify tests that support the explanation and gaps you could not verify. Report the relevant files with precise paths and line references, the essential contracts, how the pieces connect, and where to start next. Include small actual code excerpts only when they clarify a contract. Distinguish inspected facts …

How to install
mdr add jackispm/nausicaa-harness/codebase-map@sha256:18f795588837d2a7The line at the top of this page pins the label git:20260907.7726f1a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
