Today is ${today}. Operate the fleet of Aeon instances registered in memory/instances.json. Output is decision-ready: every run leads with a verdict, then a delta vs prior check, then per-instance lines that name the next concrete action.

For each registered instance, skip rows with archived: true from per-instance work (count them separately). Run the three calls per instance in parallel using & + wait and write each to /tmp/fleet/${SAFE}.{repo,runs,cron}.json:
a. Repo metadata:
gh api "repos/${REPO}" \
--jq '{full_name, pushed_at, archived, default_branch, open_issues_count}' \
> "/tmp/fleet/${SAFE}.repo.json" 2>"/tmp/fleet/${SAFE}.repo.err" &b. Workflow runs in last 24h (precise window, not "last 5"):
SINCE=$(date -u -d '24 hours ago' +%Y-%m-%dT%H:%M:%SZ)
gh api "repos/${REPO}/actions/runs?created=>${SINCE}&per_page=100&exclude_pull_requests=true" \
--jq '{total_count, runs:[.workflow_runs[]|{name,status,conclusion,created_at,html_url}]}' \
> "/tmp/fleet/${SAFE}.runs.json" 2>"/tmp/fleet/${SAFE}.runs.err" &c. Cron-state from child:
gh api "repos/${REPO}/contents/memory/cron-state.json" --jq '.content' 2>"/tmp/fleet/${SAFE}.cron.err" \
| base64 -d > "/tmp/fleet/${SAFE}.cron.json" &wait after launching all three for an instance (or batch across all instances if you trust your parallelism — keep ≤16 concurrent calls to stay under rate limit).
Classify each instance with precise thresholds:
- unreachable — repo metadata call returned non-zero (404/403/etc.)
- archived — repo metadata returns
archived: true - pending_secrets —
runs.total_count == 0for the 24h window AND repopushed_at≥ 7 days old (newly-spawned instances under 7 days stay unclassified-but-tracked) - stale —
runs.total_count == 0ANDpushed_at> 7 days old AND notarchived - degraded — ≥1 cron-state skill with
consecutive_failures ≥ 3OR (24h failure_count / total_count) ≥ 0.5 with total_count ≥ 2 - warning — 24h failure_count ≥ 1 but ratio < 0.5
- healthy — has runs in last 24h, all conclusions
successorin_progress/queued, no degraded cron-state skills
For each instance compute a next_action (one short imperative phrase):
pending_secrets→add ANTHROPIC_API_KEY at https://github.com/${REPO}/settings/secrets/actionsdegraded→investigate <skill_name> (<consecutive_failures>× in a row, last_error: <signature, ≤60 chars>)warning→monitor — <N>/<Total> runs failed in 24hstale→confirm intent: no runs in 24h, last push <relative_date>; archive or re-enableunreachable→verify access: <reason from repo.err>healthy→nonearchived→none (archived)
Compute delta vs prior state (per-instance prior.health vs current.health):
- NEW — instance not in prior state
- DEGRADED — was healthy/warning, now degraded/unreachable/stale/pending_secrets
- RECOVERED — was degraded/unreachable/stale/pending_secrets, now healthy/warning
- DROPPED — was in prior state, no longer in registry
- (no change → no delta line)
Update the registry — write back health, last_checked (ISO UTC), and next_action per instance to memory/instances.json. Preserve all other fields (purpose, parent, created, skills_enabled, etc.).
Update the state file — write the current per-instance health snapshot to memory/state/fleet-control-state.json. Update last_full_summary_date to today only when this run notifies. Increment consecutive_unreachable for unreachable instances; reset to 0 otherwise.
Log to memory/logs/${today}.md:

Dispatch Mode
Parse var: dispatch <instance|*> <skill> [var=<value>].
Resolve targets:
- If
<instance>is*, target = every registry entry whose current health ishealthy,warning, ordegraded(skip unreachable, stale, pending, archived). - Otherwise, exact name match against the registry. Not found → notify
Fleet Dispatch: instance '<name>' not in registryand stop.
For each target instance:
Validate skill exists in child:
gh api "repos/${REPO}/contents/skills/${SKILL}/SKILL.md" >/dev/null 2>&1 \ || { OUTCOME="missing_skill"; continue; }Check skill is enabled in child's aeon.yml (best-effort warning, not a block — workflow_dispatch can override

Status Mode
Generate the comprehensive snapshot, but make it scannable.
For each registered instance (skip archived from detail blocks but count them in the summary), gather in parallel:
- Repo meta:
stargazers_count,pushed_at,open_issues_count,default_branch - Last 10 workflow runs:
gh api "repos/${REPO}/actions/runs?per_page=10&exclude_pull_requests=true" \ --jq '[.workflow_runs[]|{name,status,conclusion,created_at,html_url}]' - Full
cron-state.json aeon.yml(parse enabled skills)- Last 5 commits (one-line
gh api repos/${REPO}/commits?per_page=5 --jq ...)
Compute the same delta block, but compare against the most recent prior articles/fleet-status-*.md (parse the per-instance health rows; if none exists, mark the section "no prior status to diff against").

Every run logs exactly one of these to memory:

Sandbox note
Always use gh api over raw curl (handles auth and the sandbox env-var-in-headers issue). All cross-repo calls go through gh api or gh workflow run. No outbound HTTP needed beyond what gh does internally.
Constraints
- Never delete an instance from
memory/instances.jsonautomatically — only update fields. Evenunreachableinstances stay in the registry until the operator removes them by hand. - Preserve all registry fields not explicitly written by this skill (purpose, parent, created, skills_enabled, etc.).
- Never write secrets to logs or notifications.
- Cap notification length at ~30 lines; truncate the per-instance list with
...and N morewhen needed. - Health Check stays silent when nothing changed mid-day — the daily-rollup path handles the recurring "is everything fine?" question without spam.
- Do not change the skill's tags, var semantics, or schedule without strong justification.
Write complete, working code. No TODOs or placeholders.
