skill-creator

skill-creator is a skill for Claude Code, Codex from trpc-group/trpc-agent-go. It costs 69 tokens per session (4,885 once invoked), scanned B, a copy of skill-creator, Apache-2.0.

A guide and package structure for creating or updating reusable agent skills. Skills are instruction bundles that teach an agent when and how to perform a specialised workflow.

In plain words
What is it for?
It helps design, structure, review, validate, and package skill files, scripts, references, and tool usage guidance.
Why use it?
It helps turn repeated instructions, integrations, and domain rules into a maintainable capability for future tasks.

About the project

tRPC-Agent-Go is a Go framework for building AI agent applications with language models, graph-based workflows, tools, memory, retrieval, evaluation, and observability. Go developers use it to create deployable agent systems that can integrate with A2A, AG-UI, and MCP. The catalogue add-ons provide reusable workflows and agent integrations for the framework.

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 B, and why

skill-creator scanned grade B with 1 finding 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 6d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/init_skill.py, scripts/package_skill.py, scripts/quick_validate.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.

Reads MCP configurationmediumAgent snooping

mcp.json carries server URLs and auth tokens; reading it lets a mod discover and abuse other integrations.

If the user explicitly provides a complete private config or credential-bearing endpoint for a local runtime capability, store it in a local private config file such as skill-local `mcp.json` in a writable user-managed s

About Skills

Skills are modular, self-contained packages that extend Codex's capabilities by providing specialized knowledge, workflows, and tools. Think of them as "onboarding guides" for specific domains or tasks—they transform Codex from a general-purpose agent into a specialized agent equipped with procedural knowledge that no model can fully possess.

What Skills Provide

  1. Specialized workflows - Multi-step procedures for specific domains
  2. Tool integrations - Instructions for working with specific file formats or APIs
  3. Domain expertise - Company-specific knowledge, schemas, business logic
  4. Bundled resources - Scripts, references, and assets for complex and repetitive tasks

Skill-First Capability Design

Prefer a skill when the user wants the agent to keep a reusable capability instead of only completing the current turn. A skill is the durable form for user-taught behavior: it stores when the capability should trigger, how to use it, what constraints matter, how to recover from common failures, and which resources make execution reliable.

Create or update a skill when the user asks to:

  • add, remember, teach, configure, preserve, or reuse a capability
  • connect to a tool, API, CLI, MCP endpoint, internal service, or workflow
  • encode a team process, domain rule, document convention, or review checklist
  • make future tasks follow a pattern instead of repeating instructions manually
  • restrict use by natural-language conditions such as requester, team, chat, project, environment, or business context

Do not create a skill for one-off work that is unlikely to repeat. Finish the task directly when the user only needs a single answer, file, edit, or command result and there is no durable workflow to preserve.

Use memory instead of a skill for lightweight facts, preferences, and simple standing rules that do not need an executable workflow, tools, references, examples, or recovery paths. Use a skill when the remembered item is an operational capability that future tasks should be able to run.

What ships with it

4 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.
