Codebase Sync

What it does

When your agent uses it

• Tasks that involve Codebase onboarding

Example prompts

• “/codebase-sync”

Requirements

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

Workflow steps

4 steps, taken from the step headings in SKILL.md.

1. 1Project Exploration
2. 2Semantic Index Building
3. 3Convention Discovery
4. 4Rule Generation

What it can do on your machine

Read from SKILL.md and the folder at commit 000116a. 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:

  • Bash(*)
  • Read
  • Write
  • Edit
  • Glob
  • Grep

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are json).

  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 Sync loads about 585 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 168 words of instructions outside code blocks.

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

~45

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

~585

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

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.
