What it does

Bootstrap Check is an agent skill from dev-toolings/superpowers-symfony. Verify Symfony project configuration including .env, services.yaml, doctrine settings, and framework requirements

Its SKILL.md is about 420 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `reference.md`).

It works with Symfony. The repository describes itself as: Claude Code plugin for Symfony 7.4 LTS & 8.x — 44 skills, 7 AI subagents & 13 commands for API Platform v4, Doctrine ORM 3, TDD (Pest/PHPUnit), Messenger, security & DDD. The licence is MIT.

Example prompts

  • “/bootstrap-check”

Requirements

  • A credential in APP_SECRET
  • Pre-approved tools (allowed-tools): Read, Glob, Grep

Workflow steps

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

  1. Confirm .env exists and defines APP_SECRET, DATABASE_URL and the variables the bundles need.
  2. Confirm vendor/ is installed and bin/console about runs.
  3. Compile the container (cache:clear) and list services and routes.
  4. Check the database connection and that the schema matches the mappings.
  5. Check the optional stacks present: API Platform resources, Messenger transports.

What it can do on your machine

Read from SKILL.md and the folder at commit 459bcd0. 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:

    • Read
    • Glob
    • Grep

    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 these keys or tokens, usually read from environment variables:

    • APP_SECRET

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Bootstrap Check loads about 417 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 191 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~32
When it runs · the whole SKILL.md, loaded when a task matches
~417

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.

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

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.

Bootstrap Check (Symfony)

Use when

  • Starting work on an unfamiliar or freshly cloned Symfony project.
  • The application fails to boot, the container does not compile, or routes are missing.
  • Checking .env, config/packages/*, Doctrine, API Platform or Messenger setup before a change.

Default workflow

  1. Confirm .env exists and defines APP_SECRET, DATABASE_URL and the variables the bundles need.
  2. Confirm vendor/ is installed and bin/console about runs.
  3. Compile the container (cache:clear) and list services and routes.
  4. Check the database connection and that the schema matches the mappings.
  5. Check the optional stacks present: API Platform resources, Messenger transports.

Guardrails

  • Read only: report what is missing, do not rewrite configuration while checking.
  • Never print secret values from .env or the vault.
  • Prefer ACLs or the correct user over chmod 777 for cache permission issues.
  • Run Doctrine checks against a development database, never production.

Progressive disclosure

  • Use this file for execution posture and risk controls.
  • Open references when deep implementation details are needed.

Output contract

  • The checklist with each item passed or failed.
  • The exact fix for each failure (command or file to change).
  • What was not checked, and why.

References

  • reference.md
