Cache Strategy Analysis Report

Date: 2026-10-21
Runs Analyzed: 93 cache-memory runs in the available 24-hour set
Workflows with cache-memory: 72 distinct workflow names

---

Executive Summary

The available logs cover 2026-10-20 18:36Z through 2026-10-21 18:36Z. Agent jobs ran in 84 of the 93 cache-enabled runs; 9 were skipped or had no agent job. Cache-path activity was observed in 47 runs: 42 successful reads, 2 confirmed missing-file reads, and 3 other cache-path observations. Both confirmed misses were AI Moderator reads of spam-log.json.

AI Moderator has a 4-day miss streak and a 97.1% miss rate among 34 observed runs in the available 14-day records. It is already tracked as #aw_aimod. Daily Rendering Scripts Verifier has a write-only cache: the workflow stores latest.json but never reads it. A medium-priority issue was accepted by safeoutputs; its response did not return an issue number.

Coverage is incomplete. The log summary hit its 3,000-item count limit. A continuation request using before_run_id 39550062313 expanded the local run directories from 390 to 437, but the summary still exposes that continuation cursor. The 14-day cache records also have no records for 2026-10-14 and 2026-10-15, so reported rates use the available observed-run sample.

Findings

Severity	Workflow	Miss Streak	Miss Rate (14d)	Root Cause	Issue
🟠 High	AI Moderator	4 days	97.1% (33/34 observed runs)	spam-log.json reads return ENOENT; cache state has no successful reads	Existing: #aw_aimod
🟡 Medium	Daily Rendering Scripts Verifier	0 days	n/a (write-only; 0/3 explicit misses)	Writes a verification result without reading or reusing prior results	Created today; issue number pending

🔴 Critical Issues

None found in the available cache-memory workflow configuration.

🟠 High Priority

AI Moderator — runs 39555314852 and 39617272018 both failed to read /tmp/gh-aw/cache-memory/spam-log.json with ENOENT. The workflow uses a stable repository-owner key with one-day retention and its instructions say the file can be absent after 24 hours. If cross-day spam correlation is intended, extend retention and persist the current state even when the event list is empty. Otherwise, mark these expirations as expected so they are not treated as repeated defects. Existing issue: #aw_aimod.

🟡 Medium Priority

Daily Rendering Scripts Verifier — three cache-observed runs from October 19–21 have no cache hit. The workflow instructions save /tmp/gh-aw/cache-memory/rendering-scripts-verifier/latest.json after verification and contain no read of that file. Read the prior result and compare hashes or timestamps for the relevant scripts and fixtures; reuse the prior verification when inputs are unchanged. Issue accepted today; safeoutputs did not return its number.
