What it does

Symfony Cache is an agent skill from dev-toolings/superpowers-symfony. Implement caching with the Symfony Cache component; configure pools, use tags for invalidation, prevent stampede

Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `reference.md`).

It sits in Backend & APIs, covering Caching. 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.

When your agent uses it

  • Tasks that involve Caching

Example prompts

  • “/symfony-cache”

Requirements

  • Pre-approved tools (allowed-tools): Read, Glob, Grep, Write, Edit, Bash

Workflow steps

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

  1. Identify what is recomputed and how often, and whether it can go stale.
  2. Pick the pool and adapter for the access pattern and the deployment shape.
  3. Read through CacheInterface::get() with an explicit expiry.
  4. Tag every entry by the data it derives from, and invalidate by tag on write.
  5. Enable early expiration on keys whose recomputation is expensive.

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
    • Write
    • Edit
    • Bash

    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

Symfony Cache loads about 500 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 250 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
~500

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, Glob, Grep, Write, Edit, Bash

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.

Symfony Cache (Symfony)

Use when

  • Caching expensive reads: repository results, computed values, third-party responses.
  • Choosing or configuring a pool and its adapter (filesystem, Redis, APCu, chained).
  • Invalidating by tag rather than clearing everything.
  • A hot key expires under load and every request recomputes it at once.
  • Adding HTTP cache headers, a cache warmer, or clearing pools on deploy.

Default workflow

  1. Identify what is recomputed and how often, and whether it can go stale.
  2. Pick the pool and adapter for the access pattern and the deployment shape.
  3. Read through CacheInterface::get() with an explicit expiry.
  4. Tag every entry by the data it derives from, and invalidate by tag on write.
  5. Enable early expiration on keys whose recomputation is expensive.

Guardrails

  • Set an expiry on every entry. An entry without one never leaves the pool.
  • Never put user input in a cache key unhashed, and never put secrets in one.
  • Invalidate by tag, not by clearing the pool: a full clear is a cold start.
  • A cached value is stale by definition. Do not cache what must be exact.
  • Tag invalidation needs a tag-aware adapter, so decide it when configuring the pool.

Progressive disclosure

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

Output contract

  • Pool and adapter configuration, with the expiry chosen for each entry.
  • The tag map: which write invalidates which tags.
  • Stampede protection where recomputation is expensive.
  • Evidence that a write invalidates what it should.

Can I use Symfony Cache in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add dev-toolings/superpowers-symfony --skill symfony-cache -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/symfony-cache, .gemini/skills/symfony-cache, .github/skills/symfony-cache and .opencode/skills/symfony-cache in your project.

What does Symfony Cache need to run?

SKILL.md names no scripts, command-line tools or credentials: Symfony Cache is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Glob, Grep, Write, Edit, Bash.

Does Symfony Cache access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

What licence does Symfony Cache use?

Symfony Cache is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Symfony Cache use?

About 500 tokens (SKILL.md is roughly 2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
