What it does
Codebase Orientation is an agent skill from proflead/codex-skills-library. Guide quick orientation of an unfamiliar codebase with module mapping, entry points, and local run steps. Use when a junior developer needs to get situated fast.
Its SKILL.md is about 260 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Codex Skills Library is a curated library of reusable Codex skills for developers, individuals, and teams.
When your agent uses it
- A junior developer needs to get situated fast
Example prompts
- “/codebase-orientation”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Locate entry points, build scripts, and main runtime paths.
- Map key folders, ownership, and common naming conventions.
- Identify how to run, test, and debug locally with minimal setup.
- Call out one or two safe starter tasks for learning.
What it can do on your machine
Read from SKILL.md and the folder at commit a05260c. 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
Codebase Orientation loads about 255 tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 120 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.
