What it does
Audit Exception Safety is an agent skill from ben-manes/caffeine. Audit exception safety and failure atomicity across all throw sites
Its SKILL.md is about 630 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-exception-safety”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- CacheLoader.load / loadAll / reload
- Weigher.weigh
- Expiry.expireAfterCreate / expireAfterUpdate / expireAfterRead
- Mapping functions passed to compute, computeIfAbsent, merge
- RemovalListener.onRemoval / EvictionListener
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 Exception Safety loads about 633 tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 274 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.

Audit the cache for exception safety defects. For every code path where exceptions can be thrown, determine whether the cache is left consistent.
Assume at least one exception safety bug exists. If your analysis yields zero findings, re-examine catch-commit-rethrow paths — explain specifically why no exception scenario leaves inconsistent state.
Priority #1: catch-commit-rethrow in doComputeIfAbsent and remap. This is the most commonly misunderstood pattern and historically the most fragile. Trace the EXACT sequence of committed mutations, notification delivery, and exception propagation for every exception type.
User-provided code that can throw:
- CacheLoader.load / loadAll / reload
- Weigher.weigh
- Expiry.expireAfterCreate / expireAfterUpdate / expireAfterRead
- Mapping functions passed to compute, computeIfAbsent, merge
- RemovalListener.onRemoval / EvictionListener
Runtime exceptions: 6. OutOfMemoryError during node/reference allocation 7. StackOverflowError from deep re-entrancy 8. RejectedExecutionException from executor
In the jcache adapter, also trace: CacheWriter.write/writeAll/delete/deleteAll (the spec requires partial-failure bookkeeping), EntryProcessor.process, ExpiryPolicy methods, and Copier/serialization failures in store-by-value mode.
For each throw site:
List every mutation already committed before the throw point.
Determine whether the catch block rolls back or commits.
Check for:
- Phantom entries: Node in CHM but invisible to eviction/expiration
- Orphaned references: WeakReference created but node rolled back
- Counter drift: weightedSize out of sync with actual entries
- Lost notifications: notifyEviction without notifyRemoval, or vice versa
- Leaked futures: CompletableFuture never completed
- Stuck refresh: refresh flag set but never cleared
For catch-commit-rethrow (doComputeIfAbsent, remap), verify:
- Catches Throwable, not just RuntimeException
- Committed state is fully consistent
- Original exception is preserved
For OutOfMemoryError specifically:
- Can AddTask/UpdateTask OOME orphan a CHM entry?
- Can WeakKeyReference/WeakValueReference OOME leave half-constructed node?
For each defect: state the throw site, mutations committed, inconsistent state, and a concrete triggering scenario.
