generate-skill

generate-skill is a skill for Claude Code, Codex from Benknightdark/neo-skills. It costs 61 tokens per session (989 once invoked), scanned A, original, MIT.

A guide for creating, updating, reviewing, or improving Agent Skill definition files named SKILL.md. It covers their structure, triggering descriptions, supporting files, and evaluation materials.

In plain words
What is it for?
Use it to design or revise skills, add references, scripts, assets, or evaluations, and check a skill against the official format.
Why use it?
It helps turn repeated agent instructions into clearer, reusable skill definitions that activate for the right tasks.

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

generate-skill 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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (templates/pep723.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Skill Generator Specification

Perceive

  1. Receive the user's request to create, update, convert, review, or optimize an Agent Skill.
  2. Identify the target task, usage scenarios, pain points, expected outputs, target agent client, and whether the user already has source material such as docs, runbooks, examples, code, prompts, or previous failures.
  3. If high-impact information is missing, ask concise follow-up questions before generating final files. Do not invent domain rules that should come from the user or existing project material.

Reason

  1. Load Official Agent Skills Reference: Load and analyze .agents/skills/generate-skill/reference/AgentSkillsOfficialReference.md first. Treat it as the source of truth for SKILL.md frontmatter, directory structure, progressive disclosure, description triggering, scripts, references, assets, evals, and client implementation considerations.
  2. Load Reference Patterns: Load and analyze .agents/skills/generate-skill/reference/SkillCategory.md to understand 5 core design patterns:
    • Tool Wrapper: Suitable for encapsulating APIs, libraries, or team development conventions.
    • Generator: Suitable for consistently producing structured documents in specific formats (e.g., reports, templates).
    • Reviewer: Suitable for systematically checking the quality of code or outputs (e.g., security, style).
    • Inversion: Suitable for guided requirement gathering, ensuring the Agent does not guess answers prematurely.
    • Pipeline: Suitable for complex tasks that require a strict execution order and cannot skip steps.
  3. Load Reference Templates: Load and analyze the standard templates under .agents/skills/generate-skill/templates/ (including SKILL.md, evals.json, eval_queries.json, and pep723.py) to provide standard, high-quality boilerplate content to the user.
  4. Load ReAct Guidelines: Load and analyze .agents/skills/generate-skill/reference/ReAct_vs_CLI.md when the skill involves local exploration, CLI behavior, autonomous debugging, cross-file analysis, CI/CD assistance, or another agentic operating-system workflow.
  5. Requirement Matching: Based on the user's requirement, choose the most suitable pattern or combination of patterns. Use official Agent Skills format as the baseline; Perceive/Reason/Act is optional structure, not a mandatory official requirement.
  6. Progressive Disclosure Planning: Decide what belongs in SKILL.md versus references/, scripts/, assets/, and evals/. Keep SKILL.md concise and load detailed material only when needed.
  7. Description & Validation Planning: Draft a trigger-focused description, identify likely should-trigger and should-not-trigger prompts, and plan output quality checks for important or shareable skills.

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.
