skill-authoring

skill-authoring is a skill for Claude Code, Codex from lvcoi/solidJSkills. It costs 43 tokens per session (191 once invoked), scanned A, original, MIT.

A set of instructions for creating or improving agent skills stored in SKILL.md files. It covers their scope, triggers, step-by-step process, checks, and supporting reference material.

In plain words
What is it for?
Use it to draft skill files, define when they should run, organize detailed references, add repeatable scripts, and validate the finished skill.
Why use it?
It helps turn an informal task into instructions an agent can apply consistently, while reducing unclear triggers and unverified results.

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 2mo 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.

What it actually says

Skill Authoring

Define skill scope, build concise instructions, and package reusable context.

Workflow

  1. Extract user intent and expected artifacts.
  2. Ask only the minimum clarifying questions required to avoid rework.
  3. Draft frontmatter with explicit trigger conditions.
  4. Write procedural body instructions with validation and failure handling.
  5. Move domain-heavy detail into references/.
  6. Add deterministic utilities in scripts/ when repetition exists.

Output Requirements

  • Include required frontmatter fields.
  • Keep action steps ordered and testable.
  • Include at least one verification section.
  • Avoid redundant reference duplication.

References

Load references/checklist.md before finalizing output.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
