What it does

Code Review is an agent skill from pimcore/data-hub. Evidence-first review of Pimcore pull requests — judge against a fixed review contract, hold fixes to the Pimcore quality bar, and enforce the house PHP coding guidelines. Applies to all PHP changes in this repository.

Its SKILL.md is about 1.6k 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 Contract review, Pull requests and Code review. It works with PHP. The repository describes itself as: Data delivery & consumption platform for Pimcore.

When your agent uses it

  • Tasks that involve Contract review
  • Tasks that involve Pull requests
  • Tasks that involve Code review

Example prompts

  • “/code-review”

Workflow steps

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

  1. What's claimed — the bug or the change's stated intent, in one line.
  2. Root cause vs. symptom — does the change fix the underlying cause, or paper over a
  3. All call sites covered — a change to shared behaviour must account for every caller,
  4. Right boundary — the fix belongs in the module that owns the behaviour. Backend
  5. Backward compatibility — public (non-@internal) APIs, OpenAPI schemas, DTO shapes,
  6. Regression test at the smallest seam — a behavioural fix without a test that would
  7. Docs / changelog — updated when observable behaviour changes.
  8. Remaining risks — edge cases or anything the diff leaves unverified.

What it can do on your machine

Read from SKILL.md and the folder at commit 9c58a75. 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

Code Review loads about 1.6k tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 852 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

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 852 words (~1,628 tokens).

“Review this pull request the way a senior Pimcore maintainer would: lead with a verdict, back every claim with a file:line from the diff, and judge whether the change is the best fix — not just whether it works.”
