The cache log answers questions no test can see, but only if the reader knows which event answers
which question. This adds that reader's instructions as a file an agent can be given directly:
turn recording on, prove the wiring reaches the pool, map a declaration to the event sequence it
must produce, and when the two disagree, decide whether the fault is the application's or this
library's before reporting it.

It sits at skills/bear-cache-log/SKILL.md, which the composer archive carries, so a project
installs the copy that matches the library version it actually has:

mkdir -p .claude/skills && cp -r vendor/bear/query-repository/skills/bear-cache-log .claude/skills/

That path is also the layout BEAR.Skills uses (skills/<name>/SKILL.md). The skill stays here
while the semantic log is unreleased, because the declaration-to-event table is measured against
this repository's demo/run*.php and moves with them; once the log ships in a release, moving the
skill to BEAR.Skills is a rename with no edits.

Everything in it was measured on 1.x rather than reasoned. The declaration-to-event table comes
from demo/run*.php and the weaving fixtures; the traps come from defects this cycle produced (a
#[Cacheable] final class weaves nothing, #[RefreshCache] on a write was answered from the
cache until #215, an invalidation tag drifted from the constant it was copied from). Four agents
given nothing but this file and a symptom reached the cause from the log each of the four times,
and their reports named eight gaps in it that are now fixed.

Written in Japanese, like the .ja.md documents beside it.

Docs only — no source, no tests. Both READMEs gain one line in their documentation list.

The log answers questions no test can see, but only if the reader knows
which event answers which question. This file is that reader's
instructions, written for a coding agent: turn recording on, prove the
wiring reaches the pool, map a declaration to the event sequence it must
produce, and when the two disagree, decide whether the fault is the
application's or this library's before reporting it.

Everything in it was measured on 1.x rather than reasoned: the
declaration-to-event table comes from demo/run*.php and the weaving
fixtures, the traps come from defects this cycle produced (a #[Cacheable]
final class weaves nothing, #[RefreshCache] on a write was answered from
the cache until bearsunday#215, an invalidation tag drifted from the constant it
was copied from), and four agents given nothing but this file and a
symptom reached the cause from the log each time.

Placed under docs/ with the other log documents, so a curl of the raw URL
installs it into an agent's skill directory.

📝 Walkthrough

Walkthrough

Adds a Japanese coding-agent skill for observing BEAR.Sunday cache logs, checking declared behavior against actual events, and separating application issues from library issues. Both README files link to the new skill document.

Changes

Cache log observation skill

Layer / File(s) Summary
Skill documentation and README integration
docs/skills/bear-cache-log/SKILL.md, README.md, README.ja.md
Adds the Japanese skill document and links to it from both README documentation sections. The document covers installation, semantic log events, jq/stree analysis, cache dependency checks, issue triage, and evidence-based reporting.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🟠 High · up to b8a39

The new skill can encourage unsafe production logging and produce incorrect cache diagnoses because its observation checks and version assumptions are insufficiently constrained. These issues should be corrected before merge.

- Around line 85-86: Update the diagnostic guidance around the empty jq result
and the section 5 decision table so it does not conclude that weaving failed
solely because no get scope appears. Require confirmation of a known get
operation and the active sink or session, accounting for wrong-session
inspection and flush()-only test output, before diagnosing the interceptor as
unwoven.
- Around line 54-55: Update the production example using
ProdQueryRepositoryLogModule to require a LogWriterInterface scrubbing decorator
before writing retained sessions to php://stdout; otherwise explicitly mark the
configuration unsafe until one is installed.
- Around line 19-21: Update the bear/query-repository setup in the prerequisite
section to require the exact revision documented by the expected-event table,
5abe57368553e00aa752551f7f70f63d43abcb53, rather than allowing any post-PR `#178`
commit. Keep the table and dependency revision aligned.

Comment thread skills/bear-cache-log/SKILL.md
Comment thread docs/skills/bear-cache-log/SKILL.md Outdated
docs/ is export-ignore'd, so the skill never reached an app's vendor and
the only install path was a curl into the agent's global skill directory.
skills/ ships in the archive, so a project can copy the skill that matches
the version of the library it actually installed.

The path mirrors BEAR.Skills' skills/<name>/SKILL.md: once the semantic log
ships in a release, moving the skill there is a rename with no edits.

Also qualifies the empty-jq diagnosis (an absent get scope only proves the
interceptor is unwoven once you know the session did GET a cacheable
resource) and points the production example at the note listing what a
session carries.

@coderabbitai No outstanding blockers. The skill also moved from docs/skills/ to skills/ in 1305978 so the composer archive carries it — please re-review that path change, then resolve all open conversations and approve.

@koriym Re-review complete. The Git archive contains skills/bear-cache-log/SKILL.md and excludes the old docs/skills/bear-cache-log/SKILL.md path. The README links and installation commands use the shipped path. I found no unresolved review threads and no blockers.

Learning: In `BEAR.QueryRepository`, `docs/skills/bear-cache-log/SKILL.md` identifies `5abe573` only as the revision used to measure its expected-event table. The skill must observe the version installed by the reader, so its dependency requirement uses PR `#178` as a feature floor rather than pinning `5abe573`. The Composer archive ships the matching skill at `skills/bear-cache-log`, which users install from `vendor/bear/query-repository/skills/bear-cache-log`.
