About this capability
Operate managed Aeon instances from memory/instances.json - health-check, dispatch, and status snapshots (control), plus a fleet scorecard of runs, tokens, cost, and reliability (scorecard).
What this skill tells your AI
The instructions your AI receives, as published by aeonfun/aeon in skills/fleet-control/SKILL.md and read by ahel’s review.
${var} — Command / view selector. Empty (or unrecognized) → Health Check (default control view).
status→ full Status Mode (control view).dispatch <instance|*> <skill> [var=<value>]→ Dispatch Mode: trigger a skill on one child or all healthy/degraded children (control view).scorecard→ Scorecard Mode: fleet-wide runs/tokens/cost/reliability scorecard with day-over-day deltas + alerts (scorecard view).
Today is ${today}. Operate the fleet of Aeon instances registered in memory/instances.json. The control view (health/status/dispatch) 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. The scorecard view publishes the daily fleet-wide cost/reliability scorecard.
The fleet is discovered at runtime, never hardcoded: it is this repo ("self") plus every non-archived entry in memory/instances.json (the registry fleet-control and spawn-instance maintain). With zero managed instances the scorecard simply covers the single self repo — still useful.
Shared preamble (every run)
-
Read memory — read
memory/MEMORY.mdfor high-level context and scan the last ~3 days ofmemory/logs/for recent activity; don't re-report a signal already logged there. -
Voice — if
soul/SOUL.mdandsoul/STYLE.mdexist and are populated, read them and match the operator's voice in every notification. If they are empty templates or absent, use a clear, direct, neutral tone — terse, lowercase, no fluff. -
Parse
${var}→ mode:- empty / unrecognized → Health Check Mode (control view; default)
- exactly
status→ Status Mode (control view) - starts with
dispatch→ Dispatch Mode (control view) - exactly
scorecard→ Scorecard Mode (scorecard view)
-
Route:
- Health Check / Status / Dispatch → run the Control-view pre-flight below, then the matching mode section. These modes make live
ghcalls. - Scorecard → skip the control-view pre-flight entirely and jump straight to Scorecard Mode, which gathers its own data in-run via
node scripts/fleet-scorecard.mjs.
- Health Check / Status / Dispatch → run the Control-view pre-flight below, then the matching mode section. These modes make live
Control-view pre-flight (health / status / dispatch only)
-
Verify gh auth —
gh auth statusmust succeed. If not, logFLEET_NO_AUTHtomemory/logs/${today}.mdand notifyFleet Control: gh auth missing — check GITHUB_TOKEN secret.Stop. -
Check rate limit —
REMAINING=$(gh api rate_limit --jq '.resources.core.remaining'). IfREMAINING < 50, logFLEET_RATE_LIMITED:remaining=${REMAINING}and notify a one-line warning, then stop. -
Load the registry — read
memory/instances.json. If the file is missing, write{"instances": []}to bootstrap. If.instancesis absent or[]:- Log
FLEET_EMPTY: no managed instancestomemory/logs/${today}.md. - Stop. Do NOT notify.
- Log
-
Load prior state — read
memory/state/fleet-control-state.json(create the directory and file with{"instances": {}, "last_full_summary_date": ""}if missing). Shape:{ "instances": { "<name>": { "health": "<status>", "last_checked": "<ISO>", "consecutive_unreachable": 0 } }, "last_full_summary_date": "YYYY-MM-DD" }
Health Check Mode (default — control view)
For each registered instance, skip rows with archived: true from per-instance work (count them separately). Run the three calls per instance in parallel using & + wait and write each to /tmp/fleet/${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-enable— if it should be running, dispatchaeon-doctorto that instance (Dispatch Mode) to lint for a silent config bug (unquotedschedule:/ duplicate key / broken entry) before assuming it's abandonedunreachable→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 (under the consolidated heading — see Log section):
### fleet-control
- Mode: health check
- Verdict: [FLEET_OK | NEEDS_ATTENTION:N]
- Sizes: total=N, healthy=N, warning=N, degraded=N, stale=N, pending=N, unreachable=N, archived=N
- Deltas: [list NEW/DEGRADED/RECOVERED/DROPPED, or "none"]
- Sources: gh=ok, rate_remaining=N
Notification gate — send the notification if any of:
len(deltas) > 0- today != prior
last_full_summary_date(first check of UTC day → daily rollup) - any current instance is
degradedorunreachable
Otherwise skip notify (silent no-op when nothing changed mid-day — operator isn't trained to ignore).
Notification body (when sent):
*Fleet Control — ${today}*
Verdict: <FLEET_OK | NEEDS_ATTENTION:N>
[If deltas exist]:
What changed:
- NEW: <name> (<repo>) — <health>
- DEGRADED: <name> — was <prior>, now <current>: <reason>
- RECOVERED: <name> — was <prior>, now <current>
- DROPPED: <name> — no longer in registry
Fleet (N total):
- <name> [<HEALTH>]: <repo> — <next_action>
- ...
[If first-of-day rollup]:
Counts: healthy <H> · warning <W> · degraded <D> · stale <S> · pending <P> · unreachable <U> · archived <A>
Sources: gh=ok · rate_remaining=N
Cap the per-instance list at 12 lines; if more, append ...and N more — see memory/instances.json. Always include archived in counts; never list archived rows in the per-instance section.
Dispatch Mode (control view)
Parse var: dispatch <instance|*> <skill> [var=<value>].
Resolve targets:
- If
<instance>is*, target = every registry entry whose current health ishealthy,warning, ordegraded(skip unreachable, stale, pending, archived). - Otherwise, exact name match against the registry. Not found → notify
Fleet Dispatch: instance '<name>' not in registryand stop.
For each target instance:
-
Validate skill exists in child:
gh api "repos/${REPO}/contents/skills/${SKILL}/SKILL.md" >/dev/null 2>&1 \ || { OUTCOME="missing_skill"; continue; } -
Check skill is enabled in child's aeon.yml (best-effort warning, not a block — workflow_dispatch can override
enabled: false):gh api "repos/${REPO}/contents/aeon.yml" --jq '.content' 2>/dev/null | base64 -d \ | grep -E "^[[:space:]]*${SKILL}:.*enabled:[[:space:]]*true" >/dev/null \ || NOT_ENABLED_WARN=1 -
Trigger the skill:
if [ -n "$DISPATCH_VAR" ]; then gh workflow run aeon.yml --repo "${REPO}" -f skill="${SKILL}" -f var="${DISPATCH_VAR}" \ && OUTCOME="dispatched" || OUTCOME="api_failed:$?" else gh workflow run aeon.yml --repo "${REPO}" -f skill="${SKILL}" \ && OUTCOME="dispatched" || OUTCOME="api_failed:$?" fi
Collect per-target outcomes: dispatched | missing_skill | api_failed:<code> (with optional not_enabled_warn flag).
Log:
### fleet-control
- Mode: dispatch
- Command: dispatch <inst|*> <skill> [var=...]
- Targets: N
- Dispatched: N | missing_skill: N | api_failed: N
- Per-target: [<name>: <outcome>, ...]
Notify (always, in dispatch mode):
*Fleet Dispatch*
Command: dispatch <inst|*> <skill>
Targets: <N> — Dispatched: <N>
Successful: <comma-sep names>
[If failures]:
Failed: <name>: <reason>, ...
[If not_enabled_warn]:
Warning: <name> has skill disabled in aeon.yml — dispatched anyway
If 0 dispatched out of N targets, the verdict line reads Fleet Dispatch: 0/${N} — see failures below and exit code logged is FLEET_DISPATCH_FAILED:no_targets_succeeded.
Status Mode (control view)
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 output/articles/fleet-status-*.md (parse the per-instance health rows; if none exists, mark the section "no prior status to diff against").
Write to output/articles/fleet-status-${today}.md:

Scorecard Mode (scorecard view)
Publish the daily fleet scorecard to memory/scorecard.md and append a trend row to memory/scorecard-history.csv. (Ran daily at 13:00 UTC as its own dispatch when this skill is scheduled with var: scorecard.)
0. Gather the data in-run
Run the committed collector — it discovers the fleet (self + non-archived memory/instances.json), fetches each repo's workflow runs + skill count + token-usage.csv from the GitHub API, computes the pricing/aggregation, and writes the tables. It reads its token from the environment (GH_READ_PAT — the read-only PAT declared in this skill's requires:, needed to read private fleet members — falling back to GH_TOKEN/GITHUB_TOKEN), so no secret ever touches a command line:
node scripts/fleet-scorecard.mjs # → /tmp/fleet-scorecard/{scorecard-body.md,metrics.json}
The deterministic maths lives in the script (not this run) — do not recompute or alter its numbers. A repo the token can't read is simply absent from the tables rather than crashing the collector.
Inputs (produced by step 0 — read these)
/tmp/fleet-scorecard/scorecard-body.md— the computed markdown tables (Fleet totals, Per-repo, Top skills by cost, Least reliable skills). Authoritative — do not recompute or alter them./tmp/fleet-scorecard/metrics.json— today's key totals:total_runs, total_failures, generations, prompt_tokens, cached_tokens, completion_tokens, total_tokens, est_cost_usd, cache_discount_usd.
If /tmp/fleet-scorecard/scorecard-body.md is missing or empty, the collector failed or resolved an empty fleet — write a one-line note to /tmp/skill-result.txt saying so and stop (do not overwrite the existing scorecard, do not notify).
Steps
1. Load today's metrics and yesterday's baseline
- Read
/tmp/fleet-scorecard/metrics.json(today). - Read the last row of
memory/scorecard-history.csvif it exists (the previous run's metrics) to compute deltas. If the file doesn't exist yet, this is the first run — deltas are "—".
2. Compute day-over-day deltas
For total_runs, total_failures, generations, total_tokens, est_cost_usd, cache_discount_usd, compute today − previous. Format as signed (e.g. +312 runs, +$148, +5 failures). These are cumulative all-time figures, so deltas show the last ~24h of activity.
3. Build the Alerts block
Scan the computed tables in scorecard-body.md and flag:
- Any skill in "Least reliable skills (last 14d)" with fail rate ≥ 25% (call it out by name + repo + rate). That table is already windowed to 14 days, so long-resolved incidents won't trigger false alarms — anything listed there is a current problem worth surfacing.
- Any cost spike:
est_cost_usddelta > 1.5× the median daily delta from history (if ≥7 history rows exist), or just note the day's cost increase otherwise. - If
total_failuresrose by more than 10 since yesterday, flag it. - If no issues, write
✅ No anomalies — fleet healthy.
4. Write memory/scorecard.md
Structure (overwrite the file):
# 🛰️ Aeon Fleet Scorecard — as of ${today}
_Auto-generated daily by skills/fleet-control (scorecard view). Tokens reported OpenRouter-style (cached_tokens ⊆ prompt_tokens)._
## Since last update (~24h)
| Metric | Δ |
|---|---:|
| Runs | <signed> |
| Failures | <signed> |
| Generations | <signed> |
| Total tokens | <signed, humanized> |
| Est. cost | <signed $> |
| Cache discount | <signed $> |
## Alerts
<the alerts block from step 3>
<PASTE the full contents of /tmp/fleet-scorecard/scorecard-body.md verbatim here>
---
_Sources: GitHub Actions run history + each repo's `memory/token-usage.csv`. Fleet resolved from memory/instances.json + self. Cost = Anthropic list price (estimate)._
5. Append the trend row
Append one line to memory/scorecard-history.csv (create with a header if it doesn't exist):
date,total_runs,total_failures,generations,prompt_tokens,cached_tokens,completion_tokens,total_tokens,est_cost_usd,cache_discount_usd
Use ${today} for the date and the values straight from metrics.json. Append, never rewrite prior rows.
6. Notify
Write a terse daily pulse to /tmp/scorecard-notify.md and send it with ./notify -f /tmp/scorecard-notify.md. One short paragraph — today's totals (runs, est. cost, total tokens), the headline deltas, and any alert. Example shape: "fleet at 12.5k runs, ~$7.8k notional. +312 runs / +$148 since yesterday. cost-report still failing (88% fail). caching saved ~$43k." Also copy this text to /tmp/skill-result.txt so the framework captures it.
7. Memory log
Append the scorecard entry under the consolidated ### fleet-control heading in memory/logs/${today}.md (see Log section), noting the headline numbers (so future skills like self-improve/reflect see it).
Scorecard notes
- Numbers come only from the collector's output files (
/tmp/fleet-scorecard/*) — never invent or estimate figures yourself. - The scorecard is cumulative/all-time; the deltas are what make the daily run useful.
- GitHub Actions retains runs ~90 days, so the run history is a rolling window; the token CSVs are the durable record committed in each repo.
Log
All modes append under one ### fleet-control heading in memory/logs/${today}.md, with a - Mode: discriminator line (the health loop parses this shape). Use the per-mode block shown in each mode section above. For Scorecard Mode use:
### fleet-control
- Mode: scorecard
- Scorecard: memory/scorecard.md updated — <total_runs> runs, ~$<est_cost_usd> notional, <total_tokens humanized>
- Deltas: <+runs> / <+$cost> since yesterday
- Alerts: <alert summary or "none">
Exit taxonomy
Every run logs exactly one of these to memory:
FLEET_CONTROL_OK— health/status/dispatch/scorecard completed normallyFLEET_EMPTY— no instances in registry (silent stop; control view)FLEET_NO_AUTH— gh auth missing (control view)FLEET_RATE_LIMITED:remaining=N— abandoned to preserve quota (control view)FLEET_DISPATCH_OK:N/M— dispatched N of M targetsFLEET_DISPATCH_FAILED:<reason>— dispatch produced 0 dispatchesFLEET_SCORECARD_EMPTY— collector produced no data (empty fleet / all repos unreadable); scorecard skipped without overwriting or notifying
Network note
Control view (health / status / dispatch): always use gh api over raw curl (it handles auth internally, so no $SECRET appears on the command line for the Bash permission layer to refuse). All cross-repo calls go through gh api or gh workflow run. No outbound HTTP needed beyond what gh does internally.
Scorecard view: gathers its data in-run by executing node scripts/fleet-scorecard.mjs (step 0), which fetches workflow runs + token usage from the GitHub API and computes the tables into /tmp/fleet-scorecard/. The collector authenticates with GH_READ_PAT when set (a read-only PAT with cross-repo scope, declared in this skill's requires: and injected into the run) so private managed instances are readable; when unset, the run's GH_TOKEN (= GH_GLOBAL) reads the same private members, the standard single-key setup. It reads the token from process.env internally, so the secret never appears on a command line. A repo the token can't read is simply absent from the tables rather than crashing the collector.
Required env vars
GH_READ_PAT (optional, read-only) — declared in requires: and read from process.env by scripts/fleet-scorecard.mjs (scorecard view) to reach private managed instances; it falls back to GH_GLOBAL/GH_TOKEN/GITHUB_TOKEN (the run's repo-wide token, which also reads private members) when unset, and reads GITHUB_REPOSITORY to resolve "self". The control view relies on the workflow-provided GITHUB_TOKEN for its live gh calls.
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.
- Scorecard Mode never overwrites
memory/scorecard.mdwhen the collector output is missing/empty, and appends (never rewrites) prior rows inmemory/scorecard-history.csv. - Do not change the skill's tags, var semantics, or schedule without strong justification.
Write complete, working code. No TODOs or placeholders.
