project-discovery SKILL.md skillA

project-discovery from testdouble/han is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add testdouble/han/project-discovery@git:20260818.55bdb1d

Pins git:20260818.55bdb1d in mdr.lock. Pin the fingerprint instead.

Discovers the core attributes of the current code repository and its projects — languages, frameworks, tooling, and where things live — and writes a concise reference section directly into the project's AGENTS.md or CLAUDE.md for other skills, agents, and hooks to consume. Use when scanning, analyzing, or detecting the project's technology stack, build tools, or repository structure. Does not create or update project documentation — use project-documentation for writing feature or system docs.

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

## Project Context

- Default branch: !`git symbolic-ref --short refs/remotes/origin/HEAD 2>/dev/null || echo unknown`
- AGENTS.md: !`find . -maxdepth 1 -name "AGENTS.md" -type f`
- CLAUDE.md: !`find . -maxdepth 1 -name "CLAUDE.md" -type f`
- README: !`find . -maxdepth 1 -name "README*" -type f`
- personal config directory: !`bash "${CLAUDE_PLUGIN_ROOT}/scripts/han-config-dir.sh" 2>/dev/null || echo "$HOME/.claude"`
- project .han/config.md: !`cat .han/config.md 2>/dev/null || echo ""`

As your first action, use the Read tool on `.han/config.md` inside the `personal config directory` path above. A read
that returns no file is no personal configuration: continue silently. When that file or the `project .han/config.md`
probe supplies content, apply it per [config-rule.md](../../references/config-rule.md), which governs precedence
between the two files, relative-path resolution, and what to do with a file that reads but cannot be used.

# Project Discovery

This skill discovers the project's core attributes and writes them as a concise `## Project Discovery` section
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add testdouble/han/project-discovery@sha256:10d5b00f24f95cbe

The line at the top of this page pins the label git:20260818.55bdb1d, 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.
