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:

bash

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:

bash

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
- Summary: Architectural summary, Sensitive Data Types, Business Criticality, Component Map, Evidence
Validate — Read
```
<cache_dir>/repo.md
```
back and verify it contains the expected sections from
```
<skill_dir>/template-repo.md
```
(e.g., project entries with Detection and Summary fields). If the file is missing or malformed, retry the write once before reporting an error.

Output — Return:

Repository context is at: <cache_dir>/repo.md
