install-skill

install-skill is a skill for Claude Code, Codex from aaronjmars/aeon-agent. It costs 26 tokens per session (2,241 once invoked), scanned A, a copy of install-skill, MIT.

An installer for community skill packs stored in GitHub repositories. It can install an entire pack or selected skills and submit the changes through an automatically merged pull request, a proposed code change for review.

In plain words
What is it for?
Use it to add skills from a repository, select particular skills or branches, and deliver the installation to the main branch through a pull request.
Why use it?
It avoids manually copying skills into a project while keeping installation changes reviewable and passing through security checks. Installed skills remain disabled until explicitly enabled.

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

install-skill scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

`bin/install-skill-pack` fetches the pack tarball over the network (curl to `codeload.github.com`). `curl` reaches the network fine — there is no network sandbox. If the fetch still fails:

How it starts

The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.

${var} — The community pack to install: owner/repo, optionally followed by specific skill slugs to install only a subset, and optional flags. Required. Examples:

  • AntFleet/aeon-skills — install the whole pack
  • liquidpadbot/aeon-skill-pack-liquidpad liquidpad-burn-monitor — install one skill from it
  • mnemedb/aeon-skill-pack-mneme --branch develop — install from a non-default branch

If ${var} is empty, exit INSTALL_SKILL_NO_VAR:

./notify "install-skill aborted: var empty — pass a pack repo e.g. \"owner/repo\" (optionally + skill slugs)"

Then stop.

Today is ${today}. Your task is to install the community skill pack named in ${var} into this fork and ship it as a PR that auto-merges — so the skills land on main (and show up in the dashboard) with no manual step. Never commit directly to main: the change still flows through a reviewable, CI-gated PR — it just merges itself. This is the dashboard "Install" button's backend: the operator clicked it on a Community Pack card, so be fast, safe, and honest about what landed. The safety gate is real but unchanged: every skill is security-scanned and lands disabled, so nothing executes until the operator sets secrets and flips enabled: true.

How installation works (so you can explain it and trust the output)

The repo already ships a hardened installer, bin/install-skill-pack, which is the single source of truth — do not reimplement it. Given owner/repo it:

  1. Downloads the repo tarball and reads its skills-pack.json manifest (per-skill path, schedule, default_enabled, secrets_required, capabilities). No manifest → it falls back to scanning skills/*/SKILL.md.
  2. Security-scans every skill from an untrusted source via scripts/skill-scan.sh. Sources listed in skills/security/trusted-sources.txt skip the deep scan (format checks still run). In CI there is no TTY, so a HIGH-severity finding blocks that skill unless --force is passed — this is the safety gate, leave it on.
  3. Copies each skill into skills/<slug>/, then updates aeon.yml (added enabled: false so nothing runs until the operator turns it on), skills.json, and records provenance in skills.lock.

Your job is to drive that script, regenerate the catalog, and wrap the result in a reviewable PR.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
