What it does
Audit Lifecycle is an agent skill from ben-manes/caffeine. Analyze shutdown, close, and GC-of-cache lifecycle correctness
Its SKILL.md is about 480 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: A high performance caching library for Java. The licence is Apache-2.0.
Example prompts
- “/audit-lifecycle”
Workflow steps
8 steps, taken from the first numbered list in SKILL.md.
- Operations racing with close/cleanup: get/put/compute during cleanUp()
- Scheduler lifecycle: Does the scheduled future prevent cache GC?
- Executor lifecycle: Reference cycle between cache and executor?
- Removal listener drain on shutdown: Are pending notifications delivered
- In-flight operations during shutdown
- Multiple close calls: Is close() idempotent? Concurrent close() corruption?
- Finalizer / Cleaner interactions: Reference queues outliving the cache?
- jcache manager/cache close: Is teardown symmetric with setup — the OSGi
What it can do on your machine
Read from SKILL.md and the folder at commit e972fb0. 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
Audit Lifecycle loads about 476 tokens when it runs. Until then it costs about 20 tokens; SKILL.md has 219 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 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.

Analyze the cache for defects during shutdown, close, and garbage collection of the cache instance itself.
Assume at least one shutdown or lifecycle race exists. If your analysis yields zero findings, re-examine scheduler/executor lifecycle and in-flight operations during close — explain specifically why no race is possible.
Operations racing with close/cleanup: get/put/compute during cleanUp() or GC? close() state transition? Operations after close()?
Scheduler lifecycle: Does the scheduled future prevent cache GC? Can scheduler fire after cache is collected? Is the task cancelled on close?
Executor lifecycle: Reference cycle between cache and executor? RejectedExecutionException handling when executor is shut down?
Removal listener drain on shutdown: Are pending notifications delivered or dropped? Notifications lost if executor shuts down first?
In-flight operations during shutdown:
- CacheLoader.load() in progress when cache closes
- Refresh future's whenComplete callback after close
- CompletableFuture value pending when cache closes
Multiple close calls: Is close() idempotent? Concurrent close() corruption?
Finalizer / Cleaner interactions: Reference queues outliving the cache? Reference queue processing accessing dead cache?
jcache manager/cache close: Is teardown symmetric with setup — the OSGi context-classloader swap applied on destroy/close as on create/get; in-flight futures awaited; user Closeables (writer, loader, listeners, expiry) closed exactly once under the right classloader?
For each defect: state the lifecycle transition, provide a concrete scenario, state the observable incorrect behavior.

Can I use Audit Lifecycle 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 ben-manes/caffeine --skill audit-lifecycle -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/audit-lifecycle, .gemini/skills/audit-lifecycle, .github/skills/audit-lifecycle and .opencode/skills/audit-lifecycle in your project.
What does Audit Lifecycle need to run?
SKILL.md names no scripts, command-line tools or credentials: Audit Lifecycle is instructions for the agent only.
Does Audit Lifecycle 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.
Is Audit Lifecycle safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Audit Lifecycle use?

How many tokens does Audit Lifecycle use?
About 476 tokens (SKILL.md is roughly 1.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
