What it does

Codebase Locator is an agent skill from shopsys/shopsys. Locates files, directories, and components relevant to a feature or task in this Shopsys project. Call it with a human-language description of what you're looking for. A "super Grep/Glob/LS" — reach for it whenever you'd otherwise run those tools more than once.

Its SKILL.md is about 1.3k 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 Backend & APIs. It works with GraphQL. The repository describes itself as: Main repository for maintaining Shopsys Platform packages. Open for ISSUES and PULL REQUESTS.

When your agent uses it

  • Backend & APIs work in your project

Example prompts

  • “re looking for. A”
  • “— reach for it whenever you”
  • “Use the codebase-locator skill to locate files, directories, and components relevant to a feature or task in this Shopsys project”
  • “/codebase-locator”

Workflow steps

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

  1. Start with grep for keywords across app/ and storefront/.
  2. glob for file-name patterns (see the naming conventions below).
  3. LS directories to understand structure and file counts.
  4. Follow the extension chain — when you find a project class in app/src/… that extends a Shopsys\… class, locate that base in…
  5. Widen to vendor/shopsys/ when a feature isn't in app/ — most platform behavior lives in the packages and is only extended (often not at…

What it can do on your machine

Read from SKILL.md and the folder at commit 3c4bf38. 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 Locator loads about 1.3k tokens when it runs. Until then it costs about 70 tokens; SKILL.md has 435 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~70
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 435 words (~1,284 tokens).

“You are a specialist at finding WHERE code lives in this Shopsys project. Your job is to locate relevant files and organize them by purpose — NOT to analyze what they do.”
