skill-authoring

skill-authoring is a skill for Claude Code, Codex from androoAGI/starnet. It costs 44 tokens per session (885 once invoked), scanned A, original, MIT.

A procedure for deciding whether a repeated process should become a saved skill, then writing that skill as steps another run can follow. A saved skill is a reusable procedure, not a fact or a one-time task.

In plain words
What is it for?
Use it to create, improve, or remove procedures for recurring jobs. It helps name a skill by its trigger, check for an existing version, and end the instructions with verification.
Why use it?
It keeps a skill library useful instead of filling it with duplicates, untested instructions, or information that belongs elsewhere. It also makes recurring work easier to start correctly.

About the project

StarNet is a local-first desktop harness for creating AI agents and arranging them in a pixel-art space station whose layout represents their capabilities, permissions, and workflow. It lets people run real model calls and tools through multiple bounded agents, using their own provider keys or accounts and optionally messaging the station through chat services. The catalogue entries are skills that extend or support work performed by StarNet agents.

Token cost

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

skill-authoring scanned grade A with 0 findings 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 12d ago.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.

A skill is HOW: a procedure loaded with skill.view when the job comes round again. A fact goes in the notebook; a schedule is a routine; a skill is the steps. Save one only when it will save the next run real work.

When a procedure earns a skill

  • You did it, it worked, and it will come round again.
  • It took discovery: a non-obvious order, a trap you hit, a check that caught a real mistake.
  • The Commander corrected how you did it, and the correction generalizes.

Not a skill: a one-off, a fact ("the staging server is X" belongs in the notebook), or anything you have not actually done successfully.

Method

  1. Check the library first (skill.list). It shows names, summaries, state and use counts. If a skill already covers most of this, improve it: skill.view it, then skill.manage action=patch (find/replace) or action=edit. A near-duplicate splits future runs between two half-right versions.
  2. Name it for the trigger. A short title a future run would match to the job: "Deploy the site", "Reconcile the monthly invoices". The summary is one line — what it does and when to use it. That line decides whether the skill ever gets loaded.
  3. Write the body for a reader with no context. The next run has not seen this conversation. Numbered steps, each an action with the real tool name, the real path or command, and what a good result looks like. Put each trap inside the step where it bites, not in a footnote.
  4. Make verification a step. The last step proves the result — the check you ran and the output that meant success — so the next run cannot stop at "looks done".
  5. Write the don'ts. The mistakes you made or nearly made, stated plainly: what not to do and why.
  6. Generalize without going vague. Replace today's specifics with what varies ("the invoice month") and keep the facts that do not change. Never put a key, token or password in a skill; name the environment variable instead.
  7. Declare what it needs. Pass requires with the gear the procedure uses (cabinet, dish, workbench, notebook, studio, orchestrator) and setup for prerequisites. Long reference material goes in a support file (action=write_file under references/), not the body.
  8. Save it (skill.manage action=create, or skill.write) and read the tool's answer.
  9. Load it back (skill.view) and read it as a stranger would. Fix every step you had to fill in from memory.

What this file has done since we first saw it

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.
