What it does
Repo Context is an agent skill from nduc99911/repo-context-mcp. Use repo-context-mcp tools to map, search, and pack repository context before large edits or PR review.
Its SKILL.md is about 230 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering Codebase knowledge for agents and MCP servers. It works with Model Context Protocol and TypeScript. The repository describes itself as: MCP server: repo map, code search, and token-aware context packs for AI coding agents. The licence is MIT.
When your agent uses it
- Tasks that involve Codebase knowledge for agents
- Tasks that involve MCP servers
Example prompts
- “/repo-context”
Requirements
- Node.js
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Call repo_map first to see structure and entrypoints.
- Call search_code for symbols, error strings, or feature names.
- Call pack_context with focus keywords before drafting a large patch or review.
What it can do on your machine
Read from SKILL.md and the folder at commit 767a264. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npx, 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
Repo Context loads about 233 tokens when it runs. Until then it costs about 29 tokens; SKILL.md has 90 words of instructions outside code blocks.
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.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NoteMentions a .env fileSKILL.md:19
Do not pack `node_modules`, secrets, or `.env` files (the server already skips common cases).
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.

repo-context skill
When exploring an unfamiliar codebase or preparing a change:
- Call
repo_mapfirst to see structure and entrypoints. - Call
search_codefor symbols, error strings, or feature names. - Call
pack_contextwithfocuskeywords before drafting a large patch or review.
Rules
- Prefer
pack_contextover reading dozens of files one-by-one. - Always set
rootif the workspace is a monorepo subdirectory. - Keep
max_tokensreasonable (8k–16k) for review; raise only when needed. - Do not pack
node_modules, secrets, or.envfiles (the server already skips common cases).
