${var} — A natural-language description of the skill to create. Required. Example:
"monitor Hacker News for AI papers and send a summary"or"track gas prices on Ethereum and alert when below 10 gwei".
If ${var} is empty, exit CREATE_SKILL_NO_VAR:
./notify "create-skill aborted: var empty — pass a description e.g. \"monitor X for Y\""
Then stop.
Today is ${today}. Your task is to generate a complete, production-ready skill from ${var}, score it against a quality bar, and ship it as a PR — never commit directly to main.
Steps
-
Parse the request. Extract from
${var}:- Core action verb (monitor, fetch, generate, analyze, alert, track, scan, etc.)
- Data source(s) — APIs, websites, RSS, on-chain, GitHub, etc.
- Output format — notification, article, file, PR, dashboard, etc.
- Configurable parameter(s) the new skill will accept via its own
${var} - Suggested cadence (daily, hourly, weekly, on-demand)
Save a one-paragraph structured request summary; you'll use it in the PR body.
-
Duplicate detection (deep — not just
ls). Find functional overlap, not just name collision.keywords=$(echo "${var}" | tr '[:upper:]' '[:lower:]' | grep -oE '[a-z]{4,}' \ | grep -vE '^(send|with|from|that|this|when|each|into|over|some|like|just|than|then|also|will|have|been|using|monitor|track|fetch|alert)$' \ | sort -u) for kw in $keywords; do grep -liE "$kw" skills/*/SKILL.md | head -5 doneRead the top 3 candidates fully. For each, judge: does it already do this? Could the request be solved by running an existing skill with a different
var=?- Near-duplicate exists → exit
CREATE_SKILL_DUPLICATE. Notify with the existing skill name and a one-line suggestion ("use existing{skill}withvar={...}instead"). Stop. - Functionally adjacent → design the new skill to complement (different angle/cadence/output). Document the boundary in the PR body.
- Near-duplicate exists → exit
-
Research the data sources. For every API or data source the new skill needs:
- WebSearch for the current API documentation. Cross-check against a secondary source when feasible (a recent GitHub repo using it, an official changelog, or a Stack Overflow answer dated ≥2026) to confirm the endpoint isn't deprecated.
- WebFetch the canonical docs URL — record it as a comment in the SKILL.md and in the PR body's "Sources researched" section.
- Identify exact endpoints, required headers, auth scheme, response schema, and rate limits.
- Note every required environment variable / API key.
- Determine fallback strategy when an optional API key isn't set (WebSearch / WebFetch / cached data / public endpoint).
Research bar (soft): at least one confirmed source URL or exemplar (a working docs page or a public repo using the API). If none, do not hard-abort — log
CREATE_SKILL_INSUFFICIENT_RESEARCH, ask the operator via./notifywith what was tried and why each source failed, and stop. The operator can re-dispatch with a clearer prompt or a source hint. -
New-secret guard. Secrets values are never inspectable from the workflow — only names are listed. Use
gh api repos/:owner/:repo/actions/secrets --jq '.secrets[].name'to read the names of secrets already configured (this endpoint returns names only, never values). Cross-reference with env-var usage inaeon.ymland existing workflows. For each env var the new skill needs:- Name present → continue.
- Name missing → record as
NEW_SECRET_REQUIRED. The generated skill must gracefully degrade or skip when the secret is absent (no hard crash). Add a### Required secretssection to the PR body listing what the operator must add to GitHub Actions secrets before enabling.
If the secret has no graceful fallback, the generated skill's step 1 must do:
if [ -z "$VAR" ]; then ./notify "{skill} skipped: VAR not set"; exit 0; fi -
Design the skill. Decide:
- Skill name — lowercase, hyphenated, 2-3 words max (e.g.,
gas-alert,hn-papers). Must not collide with any existing entry underskills/. - Description — one sentence, starts with a verb, ≤90 chars.
- Tags — pick from:
content,crypto,dev,meta,news,research,social. Max 3. - Variable behavior — what
${var}controls; what happens when empty (sane default OR clean abort with notify). - Steps — 4-8 numbered, following the standard pattern: read context → fetch/search → process/analyze → write output → log → notify.
- Schedule suggestion — choose a cron slot. Read existing schedules in
aeon.yml; avoid co-scheduling at the same minute as heavy skills (article, repo-scanner, deep-research, telegram-digest) unless the new skill is lightweight (<30s expected). Prefer a:30minute offset if the natural hour is already crowded. - Model — default
claude-opus-4-7. Pickclaude-sonnet-4-6if the skill is high-frequency aggregation/digestion (cost optimization). Document the choice in the PR body. - Category — the pack the skill joins. Pick one:
researchdevcryptoonchain-securitysocialproductivitymeta. (coreandfleetare curated inpacks.config.json, not chosen here.) If none fits, omit it and the skill lands in the Lab catch-all for later triage. Seedocs/skill-packs.md.
- Skill name — lowercase, hyphenated, 2-3 words max (e.g.,

Write the SKILL.md draft at
skills/{skill-name}/SKILL.mdwith this exact structure:--- name: {Display Name} category: {category} description: {One-sentence description starting with a verb} var: "" tags: [{tags}] --- > **${var}** — {What the variable controls}. {If-empty behavior}. Today is ${today}. {One sentence describing the task.} ## Steps 1. **{Step title}.** {Specific instructions — endpoints, commands, formats.} 2. **{Step title}.** {More instructions. Code blocks for curl/bash when relevant.} ... N-1. **Log.** Append to `memory/logs/${today}.md`: - Skill: {skill-name} - What was done and key outputs N. **Notify.** Send via `./notify`: {Output format template — specify ≤4000 chars, clickable URLs} ## Network note {How this skill reaches the network — ./secretcurl with an {ENV_NAME} placeholder for auth'd APIs, gh api for GitHub, curl + WebFetch fallback for public}Hard rules for the generated content:
- Complete
curlcommands with proper headers and URL encoding (no pseudo-code). jqparsing for JSON APIs.- Notification character limit explicitly stated (under 4000 chars total).
- Every link clickable (full URLs, not placeholders).
- Fallback behavior defined for every optional secret.
- Use only
${var}and${today}template variables — no other invented variables. - No TODOs, no placeholders, no "fill in later".
- Mandatory
## Network notesection (accurate model — see the## Network notein this skill for the canonical wording; there is no network sandbox).
- Complete

Quality enforcement (self-edit pass). Score the draft 1-5 across:

Post-write validation. Re-read the SKILL.md from disk and verify:
- Frontmatter YAML is parseable; required keys present.
- No literal substring matches:
TODO,FIXME,XXX,placeholder,fill in,lorem,<your-,your_api_key_here,example.com. - Every
${...}template variable resolves to${var}or${today}. - At least one
./notifyinvocation appears in the body. - At least one
memory/logs/${today}.mdwrite appears. ## Network notesection exists.
Any failure → delete the partial file and any other writes, exit
CREATE_SKILL_VALIDATION_FAILEDwith a notify listing the failed checks. No partial state. -
Register in
aeon.yml. Insert the new skill in the appropriate time-slot section:- Format:
{skill-name}: { enabled: false, schedule: "{suggested_cron}" } - Add
model: "claude-sonnet-4-6"if chosen in step 5. - Add
var: ""if the skill takes a default var. - Add a brief trailing comment if the name doesn't make purpose obvious.
- Place near related skills (crypto with crypto, content with content, etc.).
- Always

Verify YAML still parses after the edit. If parsing fails, revert the change and exit

Network note
There is no network sandbox — curl works, with WebFetch as the fallback for a flaky public GET during research. For an auth'd API the new skill will call, route it through ./secretcurl with a {ENV_NAME} placeholder (the key injected via the skill's requires:), and gh api for GitHub. Irreversible side-effects (email, spend, on-chain writes, deploys) run in-run via ./secretcurl as the skill's final, fail-closed action — there is no deferred/postprocess step, and never defer a read (see CLAUDE.md).
Constraints
- Never commit a generated skill directly to
main. Always open a PR. - Never enable a generated skill in
aeon.yml(enabled: falsealways — operator decides). - Never add an API key/secret to the workflow that isn't already there. Surface as
NEW_SECRET_REQUIREDand document in the PR body. - Never ship a skill that fails validation. Aborting cleanly is always better than shipping broken.
- Never overwrite an existing
skills/{name}/SKILL.md— name collisions are blocking errors.
