symfony:executing-plans

A workflow guide for making medium or complex changes in Symfony, a PHP web framework. It uses TDD, meaning you write a failing test, make it pass, and then improve the code, with checks at each stage.

In plain words
What is it for?
Use it to plan and carry out Symfony architecture or workflow changes, validate checkpoints, and record remaining risks and follow-up work.
Why use it?
It reduces the risk of large changes breaking existing behavior by encouraging small steps, validation, and clear records of decisions. It also helps avoid broad refactoring without a specific need.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

symfony:executing-plans scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Executing Plans (Symfony)

Use when

  • Refining architecture/workflows/context handling in Symfony projects.
  • Planning and executing medium/complex changes safely.

Default workflow

  1. Establish current boundaries, constraints, and coupling points.
  2. Propose smallest coherent architectural adjustment.
  3. Execute in checkpoints with validation at each stage.
  4. Summarize tradeoffs and follow-up backlog.

Guardrails

  • Use existing project patterns by default.
  • Avoid broad refactors without explicit need.
  • Keep decision log clear and auditable.

Progressive disclosure

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

Output contract

  • Architecture/workflow changes.
  • Checkpoint validation outcomes.
  • Residual risks and next steps.

References

  • reference.md
  • docs/complexity-tiers.md
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

symfony:executing-plans is a skill published in the GitHub repository dev-toolings/superpowers-symfony (206 stars, last pushed 27d ago), licensed MIT. It adds 25 tokens to every session and 238 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
