Skill Installer
Helps install skills. By default these are from https://github.com/openai/skills/tree/main/skills/.curated, but users can also provide other locations.
Use the helper scripts based on the task:
- •List curated skills when the user asks what is available, or if the user uses this skill without specifying what to do.
- •Install from the curated list when the user provides a skill name.
- •Install from another repo when the user provides a GitHub repo/path (including private repos).
Install skills with the helper scripts.
Communication
When listing curated skills, output approximately as follows, depending on the context of the user's request: """ Skills from {repo}:
- •skill-1
- •skill-2 (already installed)
- •... Which ones would you like installed? """
After installing a skill, tell the user: "Restart Codex to pick up new skills."
Scripts
All of these scripts use network, so when running in the sandbox, request escalation when running them.
- •
scripts/list-curated-skills.py(prints curated list with installed annotations) - •
scripts/list-curated-skills.py --format json - •
scripts/install-skill-from-github.py --repo <owner>/<repo> --path <path/to/skill> [<path/to/skill> ...] - •
scripts/install-skill-from-github.py --url https://github.com/<owner>/<repo>/tree/<ref>/<path>
Behavior and Options
- •Defaults to direct download for public GitHub repos.
- •If download fails with auth/permission errors, falls back to git sparse checkout.
- •Aborts if the destination skill directory already exists.
- •Installs into
$CODEX_HOME/skills/<skill-name>(defaults to~/.codex/skills). - •Multiple
--pathvalues install multiple skills in one run, each named from the path basename unless--nameis supplied. - •Options:
--ref <ref>(defaultmain),--dest <path>,--method auto|download|git.
Notes
- •Curated listing is fetched from
https://github.com/openai/skills/tree/main/skills/.curatedvia the GitHub API. If it is unavailable, explain the error and exit. - •Private GitHub repos can be accessed via existing git credentials or optional
GITHUB_TOKEN/GH_TOKENfor download. - •Git fallback tries HTTPS first, then SSH.
- •The skills at https://github.com/openai/skills/tree/main/skills/.system are preinstalled, so no need to help users install those. If they ask, just explain this. If they insist, you can download and overwrite.
- •Installed annotations come from
$CODEX_HOME/skills.

SDF Interleaving
This skill connects to Software Design for Flexibility (Hanson & Sussman, 2021):
Primary Chapter: 8. Degeneracy
Concepts: redundancy, fallback, multiple strategies, robustness
GF(3) Balanced Triad
skill-installer (−) + SDF.Ch8 (−) + [balancer] (−) = 0
Skill Trit: -1 (MINUS - verification)
Connection Pattern
Degeneracy provides fallbacks. This skill offers redundant strategies.
Cat# Integration
This skill maps to Cat# = Comod(P) as a bicomodule in the equipment structure:
Trit: 0 (ERGODIC) Home: Prof Poly Op: ⊗ Kan Role: Adj Color: #26D826
GF(3) Naturality
The skill participates in triads satisfying:
(-1) + (0) + (+1) ≡ 0 (mod 3)
This ensures compositional coherence in the Cat# equipment structure.
