docs(cron): split the hourly audit prompt so a fire reads rules, not the evidence archive - #296
docs(cron): split the hourly audit prompt so a fire reads rules, not the evidence archive#296jaylfc wants to merge 1 commit into
Conversation
…the evidence archive The canonical hourly monitor prompt was a single 23,466-character paragraph (12 lines, one blank-line block) re-read in full on every :13 fire. Every rule sat interleaved with the measured incident that produced it, so a fire could not read the steps without also paying for the history, and could not skip to one step because there were no sections to skip to. Split with no rule deleted: - audit-cron-prompt.md keeps its name, so the cron prompt, STATUS.md and the handoff docs all still resolve, and now carries every rule in imperative form under nine STEP headings. 24,011 -> 14,596 bytes for a full read, and a fire that needs only STEP 4 can now read that section instead of the file. - audit-cron-rationale.md holds the original paragraph verbatim (proven byte-identical) behind a header saying to read it before changing a rule or when a guard fires. Checked for loss mechanically rather than by eye: extracted every path, script, URL, field name, threshold and command token from the original and diffed the sets. Five were absent from the steps file on the first pass; CronCreate and the usage_publish.sh path were real losses and are restored, the other three are prose-only measurements that belong in the archive. One deliberate deviation: the original told sessions to pass durable on the cron. That flag is a documented no-op and the same paragraph then says session crons die with the session, so the steps file states the flag does nothing rather than carrying the contradiction forward.

📝 WalkthroughWalkthroughThe audit cron prompt now uses structured operational steps for usage validation, scheduling, recovery, monitoring, documentation, repository checks, freshness checks, and final reporting. A rationale archive preserves the complete prompt and its operational evidence. ChangesAudit cron operations
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The prompt split preserves the entry point and archive, but the current instructions still leave account selection ambiguous for the API fallback, arm recovery too late, validate the backup cron too loosely, and leave some boundary and fallback behavior undefined. These gaps could cause wrong-account access or missed recovery and repair actions, so fixes or explicit owner acceptance are needed before merge. Possibly related PRs

“HEARTBEAT FIRST” cron check to validate exactly one entry whose five cron
fields are 51 */2 * * * and whose command uses the exact
~/.taosmd-agent/backup_watch.py path; reject zero, duplicate, malformed, or

idempotent behavior, stale-pair cleanup, and the current-window resets_at check.

Move resume-pair arming before pause work.
The ARM-AT-START step appears after the usage-band, handoff, and resume procedures. A session can hit the hard limit before it reaches Line [119], leaving no recovery pair. Arm the pair immediately after resolving a valid resets_at, before any producing or handoff work. Make this path depend only on the scheduling substeps.

Validate the backup cron schedule, not only its path.
The grep taosmd-agent/backup_watch check accepts a wrong schedule, duplicate entry, or comment containing the path. The prompt can then skip repair while the backup is not scheduled at 51 */2. Match all five cron fields and the exact script path. Treat zero or multiple matches as unhealthy.

Closes part 2 of card
tsk-qrp3sz(the self-inflicted token eaters I diagnosed at bus 3003).The problem
.claude/audit-cron-prompt.mdis the canonical prompt for the hourly:13monitor. It was one paragraph of 23,466 characters (the whole file is 12 lines, one blank-line-separated block) and every fire read all of it.Two costs, and the second is the worse one:
What changed
Nothing was deleted. The file was split by role:
audit-cron-prompt.md(same name, same path)STEPheadingsaudit-cron-rationale.md(new)Keeping the original filename as the entry point means the cron prompt,
STATUS.mdand the handoff docs all still resolve, and the cron itself needs no change (verified:STATUS.mdis the only tracked in-repo reference).Full read drops 24,011 to 14,596 bytes, about 39%. The bigger win is not the byte count: the file is now section-addressable, so a targeted fire can read one
STEPinstead of the whole thing.Proof it is zero-loss
The rationale file's body is proven byte-identical to the original:
For the steps file I did not check by eye, because "I read it and it looks complete" is exactly how a rule goes missing silently. I extracted every path, script name, URL, field name, numeric threshold and command token from the original and diffed the sets:
CronCreateand the~/.taos-team/usage_publish.shpath were real losses and are restored.~147hand~17xare prose-only measurements that belong in the archive.usage_publish.shbare is a substring artefact of the qualified path being present.All nine
STEPsections present:0a,0a-bis,0b,1,2,3,4,5,6.One deliberate deviation
The original told sessions to pass
durableon the cron. That flag is a documented no-op, and the same paragraph then says session crons die with the session, so the file contradicted itself. The steps file states the flag does nothing rather than carrying the contradiction forward. Flagging it because it is a content change, not a reorganisation.Note for review
Self-authored, not a lane PR, so it does not need the adversarial treatment the exec lane PRs get. The thing worth a second pair of eyes is the completeness claim above: the token-set diff is mechanical, but a rule expressed only in prose (no path, no number, no field name) would not be caught by it.
