Review: PR #135 — feat(sweeper): prune old session JSONL files in agent projects/ dirs
CI: ✅ green (run #1701, 3m15s)
Round: 1 (no prior reviews from this reviewer)
❌ Critical:
session_history_ttl_daysconfig override is never wired into the sweeperFile:
src/main.ts(not changed in this PR)Issue: The acceptance criterion says:
webhook-config.tsnow correctly parsessession_history_ttl_daysfromagents.jsonand stores it asWebhookConfig.sessionHistoryTtlDays.SweeperConfighas asessionHistoryTtlDays?injection field. Butmain.tsnever passes it:Because
sessionHistoryTtlDaysis omitted, the sweeper always falls back toDEFAULT_SESSION_HISTORY_TTL_DAYS = 30, making thesession_history_ttl_dayskey inagents.jsona no-op in production.Fix: add
sessionHistoryTtlDays: webhookConfig.sessionHistoryTtlDaysto thestartSweeper(...)call inmain.ts, wherewebhookConfig = getWebhookConfig()(already available in scope at that point inmain).Everything else looks good
readLiveSessionIdscorrectly readsObject.values()from the{ key → id }sessions.json map — matches the format confirmed insessions.ts.pruneSessionHistoryJSONLis best-effort (log + continue on per-file errors), correctly guards live sessions by UUID, skips non-.jsonlentries, and handles missingprojects/gracefully.ageMs > ttlMs(strict greater-than) is conservative and correct.SweeperConfig.agentEnvDirsandliveSessionsFileinjection points are used correctly in tests and fall back to production sources when absent.CLAUDE.mdsweeper row updated. ✅SweepResult.sessions_prunedsurfaced onPOST /sweep. ✅container?.enabled === true) matches the issue requirement. ✅Fixed in
2dfa2d9: addedsessionHistoryTtlDays: webhookConfig.sessionHistoryTtlDaysto thestartSweeper(...)call inmain.ts.webhookConfigis already in scope at that point (assigned on line 1025), so the value parsed fromagents.jsonnow correctly flows through to the sweeper instead of always falling back to the 30-day default.Review: REQUEST_CHANGES

CI was still running at review time (run for
09dc6e1status:running) — wait for it to complete and re-check. No new code issues found; all acceptance criteria from #131 are met.Summary of full review (round 4, manual re-trigger after final fix):
The implementation is correct end-to-end:
pruneSessionHistoryJSONL): correctly walks<credentialsHostDir>/projects/<cwdDir>/*.jsonl, guards on live session IDs before checking mtime, deletes only expired non-live files, best-effort per file. ✅readLiveSessions): readssessions.jsonas{ key → id }, extracts string UUID values into aSet— matches the sessions store format. ✅session_history_ttl_daysparsed inwebhook-config.ts, passed to bothstartSweeperandhandleSweepviagetWebhookConfig()?.sessionHistoryTtlDays. Final fix in09dc6e1confirmed present. ✅listResolvedAgents().filter(a => a.container?.enabled === true)correctly skips non-container agents. ✅SweepResult.sessions_pruned: returned fromrunSweep, surfaced onPOST /sweep. ✅If CI passes green, this is ready to merge.
