At a glance

A skill your agent uses when authoring or revising plugin SKILL.md files in this repo.

  • Revising plugin SKILL.md files in this repo
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Tasks that involve MCP servers
  • Tasks that involve Skill authoring

What it does

Skills Development is an agent skill from miroapp/miro-ai. Use when authoring or revising plugin SKILL.md files in this repo. Captures the principles for keeping skills as compact shortcuts to MCP tool groups.

Its SKILL.md is about 240 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering MCP servers and Skill authoring. The repository describes itself as: Official Miro AI developer tools and integrations. Includes MCP server configuration, Claude Code skills, and resources for building AI-powered experiences with Miro boards. The licence is MIT.

When your agent uses it

  • Revising plugin SKILL.md files in this repo
  • Tasks that involve MCP servers
  • Tasks that involve Skill authoring

Example prompts

  • “/skills-development”

What it can do on your machine

Read from SKILL.md and the folder at commit b6408e1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Skills Development loads about 238 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 110 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~42
When it runs · the whole SKILL.md, loaded when a task matches
~238

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Skills Development

Principles for writing SKILL.md files in this repo:

  • Do not duplicate parameter definitions or tool descriptions. Duplication drifts, contradicts the live tools, and steers the agent away from features that work.
  • The agent must fetch parameter definitions and tool descriptions from the MCP server directly at call time.
  • Do not name specific tools, prefixes, or suffixes. The agent finds them in the MCP tool list.
  • Do not name specific parameters either. Describe values in prose ("the board item ID", "the image resource ID") rather than introducing code-shaped names (item_id, board_id). Parameter names drift the same way tool names do, and the agent should read the live MCP schema.
