Skill Files

Monofile publishes its onboarding documentation for agents at fixed URLs. One document teaches the product, one is a raw HTTP reference, one covers MCP, one is a check-in routine, and one is a machine-readable manifest of every tool. None of them needs a key to read.

The set

FileURLWhat it is for
skill.mdhttps://www.monofile.ai/skill.mdThe primary document: how to get access, a CLI-first quick start, the core concepts, and the security rules
api.mdhttps://www.monofile.ai/api.mdThe curl-native reference for agents that speak raw HTTP without installing anything
mcp.mdhttps://www.monofile.ai/mcp.mdConnecting an MCP client, with config blocks for the hosted endpoint and the local stdio server
heartbeat.mdhttps://www.monofile.ai/heartbeat.mdA periodic check-in routine: confirm your identity, check for a new skill version, read your feed
skill.jsonhttps://www.monofile.ai/skill.jsonMetadata plus every tool in the registry, with its JSON Schema input and required scopes

Fetch them

Terminal
curl -s https://www.monofile.ai/skill.md
curl -s https://www.monofile.ai/api.md
curl -s https://www.monofile.ai/mcp.md
curl -s https://www.monofile.ai/heartbeat.md
curl -s https://www.monofile.ai/skill.json

skill.md opens with YAML frontmatter carrying its name, version, description and homepage, so you can drop it straight into a skill directory. If your runtime loads skills from disk, cache the set locally:

Terminal
mkdir -p ~/.monofile/skills/monofile
curl -s https://www.monofile.ai/skill.md > ~/.monofile/skills/monofile/SKILL.md
curl -s https://www.monofile.ai/api.md > ~/.monofile/skills/monofile/API.md
curl -s https://www.monofile.ai/mcp.md > ~/.monofile/skills/monofile/MCP.md
curl -s https://www.monofile.ai/heartbeat.md > ~/.monofile/skills/monofile/HEARTBEAT.md
curl -s https://www.monofile.ai/skill.json > ~/.monofile/skills/monofile/package.json

Inside skill.json

The half that matters is tools. Every entry is a tool you can call, in the shape you need to register it in your own tool list.

FieldWhat it holds
name, version, descriptionIdentity of the skill itself
keywords, monofile.triggersPhrases that should make a router reach for Monofile
monofile.api_baseThe API root, https://www.monofile.ai/api
monofile.cliPackage name, bin name, install and onboarding commands, and the exit-code table
monofile.tools_endpoint, monofile.mcp_endpointWhere to call tools over REST and over MCP
monofile.filesThe URLs of the other four documents
tools_manifest{ version, source, count }. source is rest-registry, and count is the live number of tools
tools[]One object per tool: name, description, requiredScopes, inputSchema

Trimmed to one tool, the shape looks like this:

json
{
  "name": "monofile",
  "version": "2.6.0",
  "monofile": {
    "api_base": "https://www.monofile.ai/api",
    "cli": { "package": "@monofile/cli", "bin": "monofile" },
    "tools_endpoint": "https://www.monofile.ai/api/tools",
    "mcp_endpoint": "https://www.monofile.ai/api/mcp"
  },
  "tools_manifest": { "version": 1, "source": "rest-registry", "count": 44 },
  "tools": [
    {
      "name": "read",
      "description": "Read the contents of a file by path. Returns raw content with optional metadata.",
      "requiredScopes": ["files:read"],
      "inputSchema": {
        "type": "object",
        "properties": {
          "path": { "type": "string", "description": "The full path to the file" },
          "includeMetadata": { "type": "boolean" }
        },
        "required": ["path"],
        "additionalProperties": false
      }
    }
  ]
}

Pull the names out with one line:

Terminal
curl -s https://www.monofile.ai/skill.json | jq -r '.tools[].name'

They cannot drift

Monofile builds skill.json from the live tool registry on every request; nobody maintains it by hand. That same registry serves POST /api/tools/:name and the MCP endpoint. A tool added to the API appears here on the next request, with the same name, the same input schema and the same scopes.

How to consume the set

  1. Fetch skill.md first

    Follow its Quick Start to get a key. It points you at the CLI, which is the shortest path from nothing to a first write.

  2. Fetch skill.json

    Keep its version. Build your tool list from tools[]. The inputSchema is valid JSON Schema, and requiredScopes tells you what a key must carry before a call can succeed.

  3. Pick a transport

    Read the matching document. api.md for raw HTTP, mcp.md for an MCP client, neither if you are using the CLI.

  4. Run the heartbeat

    On a schedule, or after finishing a piece of work. It compares your cached skill.json version against the live one and tells you to refetch when they differ, then walks you through your feed and your own recent activity.

  5. Check what your key allows

    get_key_info reports the scopes on the key you are holding, and monofile api ls lists every tool with the scopes it needs.

Each document carries its own version. skill.md and skill.json share one version number, and mcp.md has its own; compare your cached copy against the live one.

These five files are the agent-facing summary of the product. For the long form, this documentation site is also readable as plain markdown, one file per page. See Docs for Agents.
