Repository Context Builder
You gather repository context by detecting projects, summarizing their architecture, and writing the results to repo.md. Do all work yourself — do not spawn subagents or delegate.
Inputs
Parse these from $ARGUMENTS (key=value pairs):
- repo_path : path to the repository root
- cache_dir : path to the cache directory (defaults to
~/.ghost/repos/<repo_id>/cache)
$ARGUMENTS
If cache_dir is not provided, compute it:
repo_name=$(basename "$(pwd)") && remote_url=$(git remote get-url origin 2>/dev/null || pwd) && short_hash=$(printf '%s' "$remote_url" | git hash-object --stdin | cut -c1-8) && repo_id="${repo_name}-${short_hash}" && cache_dir="$HOME/.ghost/repos/${repo_id}/cache" && echo "cache_dir=$cache_dir"
Tool Restrictions
Do NOT use WebFetch or WebSearch. All work must use only local files in the repository.
Setup
Discover this skill's own directory so you can reference agent files:
skill_dir=$(find . -path '*/skills/repo-context/SKILL.md' 2>/dev/null | head -1 | xargs dirname)
echo "skill_dir=$skill_dir"
Check Cache First
Check if <cache_dir>/repo.md already exists. If it does, skip everything and return:
Repository context is at: <cache_dir>/repo.md
If it does not exist, run mkdir -p <cache_dir> and continue.
Workflow
-
Detect Projects — Read <skill_dir>/detector.md and follow its instructions against <repo_path>. Save the full detection output (project details needed for step 2). If detection finds no projects, write a minimal repo.md noting "No projects detected" and skip to step 4.
-
Summarize Each Project — Read <skill_dir>/summarizer.md. For EACH project detected in step 1, follow the summarizer instructions using that project's details (id, type, base_path, languages, frameworks, dependency_files, extensions, evidence). Collect the summary for each project. If summarization fails for a project, note it as "summary unavailable" and continue with remaining projects.
-
Write repo.md — Combine detection and summary results into <cache_dir>/repo.md using the format in <skill_dir>/template-repo.md. For each project include:
- Detection: ID, Type, Base Path, Languages, Frameworks, Dependency Files, Extensions, Evidence
