At a glance

Create and maintain Revyl tests through MCP tools using create/update operations and execution feedback loops.

  • Works in 3 steps: Build YAML from ordered instructions and… → Create or update → Execute and inspect
  • Tasks that involve MCP servers
  • SKILL.md covers Core MCP Flow, Authoring Rules, Canonical YAML and Shared Setup Reuse
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Revyl MCP Create is an agent skill from RevylAI/revyl-cli. Create and maintain Revyl tests through MCP tools using create/update operations and execution feedback loops.

Its SKILL.md is about 460 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol.

When your agent uses it

  • Tasks that involve MCP servers

Example prompts

  • “/revyl-mcp-create”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Build YAML from ordered instructions and validations.
  2. Create or update
  3. Execute and inspect

What it can do on your machine

Read from SKILL.md and the folder at commit 496d6f4. 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 (its code samples are yaml).

    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

Revyl MCP Create loads about 455 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 128 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~32
When it runs · the whole SKILL.md, loaded when a task matches
~455

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 128 words (~455 tokens).

“Use this skill when tests should be authored and managed through MCP tools.”
