What it does
Repo Map is an agent skill from ejboy/agent-scripts. Compatibility skill for existing RepoMap instructions. RepoLink and repolink are canonical for new usage.
Its SKILL.md is about 180 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 Development, covering Codebase onboarding. The repository describes itself as: Token-efficient, local-first CLI tools for coding agents - compact Maven, npm/Node, and Go test output plus reusable development helpers. The licence is MIT.
When your agent uses it
- Tasks that involve Codebase onboarding
Example prompts
- “/repo-map”
What it can do on your machine
Read from SKILL.md and the folder at commit cb132f2. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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 Map loads about 178 tokens when it runs. Until then it costs about 29 tokens; SKILL.md has 81 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 passed
The automated check found no risky patterns in SKILL.md.
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.

RepoMap compatibility
This skill remains available for existing agent configurations. RepoLink is the
current tool name and repolink is its canonical command. Follow project
instructions before using it.
Use repolink for targeted lookups:
repolink get NAMEfor a known repositoryrepolink command NAMEfor a known helperrepolink commandsonly when the needed registered command is unknown
If repolink is unavailable, use the current workspace or ask the user for the
repository location. Do not download or install Agent Scripts automatically.
