What it does
Rector Live Test is an agent skill from palantirnet/drupal-rector. Runs a rector against real D11-compatible contrib modules to verify it transforms real-world code correctly, then captures the PHPStan deprecation message it covers. Delegates finding the modules to the contrib-search skill. Pass rector class name or issue number as argument.
Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `setup-rector-test.sh`).
It works with PHP. The repository describes itself as: A developer utility for automatically upgrading deprecated code for Drupal 9.
Example prompts
- “/rector-live-test”
Requirements
- Python 3
- A Bash shell
- Pre-approved tools (allowed-tools): Read, Bash, Glob, Skill
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Find D11-compatible contrib modules that exercise the rector
- Run the rector
- Capture the PHPStan deprecation message
- Report results
- Diagnose zero-match results
What it can do on your machine
Read from SKILL.md and the folder at commit 3c58496. 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:
ReadBashGlobSkill
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships script files (Shell), which the agent can run.
Shell commands in SKILL.md call:
gitbashpython3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
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
Rector Live Test loads about 2.3k tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 781 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Bash, Glob, Skill
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
Without a licence we can't republish the file, so here is its outline and opening line. It has 781 words (~2,310 tokens).
