create-skill

Um processo para criar ficheiros SKILL.md completos para novas competências de agentes. Esses ficheiros descrevem quando usar uma competência, o que ela recebe, como trabalha e o que produz.

In plain words
What is it for?
Serve para criar uma pasta de competência, definir os seus comandos e condições de uso e documentar entradas, resultados, limites e referências reutilizáveis.
Why use it?
Evita criar instruções incompletas ou inconsistentes para uma nova competência. Inclui verificações de estrutura, segurança e qualidade baseadas nas regras do projeto.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code, Codex.

Per session 22 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.
When invoked 539 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

create-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 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.

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 — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Create Skill

Purpose

Generate complete SKILL.md artifacts for one skill folder, with explicit constraints and reusable references.

When To Use

  • Use this skill when creating a new skill folder under skills/.
  • Use this skill when regenerating a SKILL.md file to align with repository skill standards.
  • Do not use this skill for validating an existing skill.

How to Invoke

Load or attach this file's contents into your AI session to activate the workflow (paste, upload, or reference with #file:skills/create-skill/SKILL.md in VS Code Copilot Chat). In Claude Projects, add it to project knowledge. See Invoking Skills in the README for full platform guidance.

Required Inputs

  • Skill slug (name) and target folder path.
  • Capability summary and usage triggers.
  • Required inputs, workflow outputs, and failure boundaries.
  • Safety and portability constraints.

Workflow

  1. Run discovery sequence in references/discovery-phases.md.
  2. Apply schema and field rules from references/field-constraints.md.
  3. Assemble required body sections using references/output-schema.md.
  4. Apply safety constraints from references/safety.md.
  5. Produce final artifact using references/output-format.md.
  6. Validate against references/quality-checklist.md before final output.

Output Expectations

  • One complete SKILL.md artifact at skills/{name}/SKILL.md.
  • Frontmatter and folder-name parity are correct.
  • Body sections are complete, actionable, and concise.
  • Output remains provider-neutral and portable.

Resources

  • Discovery workflow: references/discovery-phases.md
  • Field constraints: references/field-constraints.md
  • Output schema: references/output-schema.md
  • Safety policy: references/safety.md
  • Output contract: references/output-format.md
  • Quality checklist: references/quality-checklist.md
  • Skill template: ../../templates/skill_template/SKILL.md

Constraints And Safety

  • Keep skill instructions concise and execution-oriented.
  • Avoid provider-specific lock-in wording.
  • Use relative paths for local references.
  • Treat allowed-tools as optional/experimental unless explicitly required.

Files

What ships with it

7 files 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.

create-skill is a skill published in the GitHub repository MSiccDev/ai-context-kit (12 stars, last pushed 4d ago), licensed MIT. It adds 22 tokens to every session and 539 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
