Ghost Repo Context

What it does

When your agent uses it

• The user needs a codebase overview
• Project structure map
• Repository context before security analysis

Example prompts

• “Use the ghost-repo-context skill to scan directory structure, detects projects, maps dependencies, and documents code organization into a repo.md file”
• “/ghost-repo-context”

Requirements

• Pre-approved tools (allowed-tools): Read, Write, Edit, Glob, Grep, Bash

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

1. 1Detect Projects — Read /detector.md and follow its instructions against . Save the full detection output (project details needed for step…
2. 2Summarize Each Project — Read /summarizer.md. For EACH project detected in step 1, follow the summarizer instructions using that project's…
3. 3Write repo.md — Combine detection and summary results into /repo.md using the format in /template-repo.md. For each project include
4. 4Validate — Read /repo.md back and verify it contains the expected sections from /template-repo.md (e.g., project entries with Detection…
5. 5Output — Return: Repository context is at: /repo.md

What it can do on your machine

Read from SKILL.md and the folder at commit 25fdf06. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Read
  • Write
  • Edit
  • Glob
  • Grep
  • Bash

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • git

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ghost Repo Context loads about 786 tokens when it runs. Until then it costs about 63 tokens; SKILL.md has 293 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~63

When it runs · the whole SKILL.md, loaded when a task matches

~786

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
