WHAT IT DOES

What skill_author does on Rokha

AI agents use skill_author to create or update resources in Rokha, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Rokha environment.

Parameter	Type	Required	Description
`name`	string	Yes	Skill id + folder name. kebab-case, ≤64 chars.
`license`	string	—	Optional. A license name or bundled-file reference (e.g. 'MIT').
`metadata`	object	—	Optional. Arbitrary string→string metadata (e.g. {"author":"example-org","version":"1.0"}).
`description`	string	Yes	What it does + when to use it. Third person, with trigger words. ≤1024 chars.
`instructions`	string	Yes	The Markdown body. Specific + imperative. When-to-use → Instructions → Examples → Guidelines.
`allowed_tools`	string	—	Optional. SPACE-separated, least-privilege tool allowlist with optional scoping (e.g. 'Bash(git:*) Read'). Experimental.
`compatibility`	string	—	Optional, ≤500 chars. Runtime/environment requirements (e.g. 'Requires Python 3.14+ and uv'). Omit for pure-instruction skills.

Parameters from the server's own tool schema.

RECOMMENDED RULE

The rule that runs skill_author safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Rokha, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For skill_author, this is the rule to start with:

skill_author Rate-limited

skill_author stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Rokha, apply this rule, and every skill_author call is checked against it from then on.

FAQ

Questions about skill_author

What does the skill_author tool do? +

Author a standard agentskills.io Agent Skill and get back its SKILL.md. A strong skill has: a name in kebab-case (lowercase letters, numbers, single hyphens, ≤64 chars); a description stating WHAT it does AND WHEN to use it, third person, with concrete trigger words (the field agents read to decide whether to load it); and instructions (the Markdown body), specific + imperative, ideally shaped When-to-use → Instructions → Examples → Guidelines. Optional compatibility (runtime/environment requirements, ≤500 chars — set when the skill needs system packages, a language version, network access, or scripts; omit for pure-instruction skills), allowed_tools (a SPACE-separated, least-privilege allowlist with optional scoping, e.g. 'Bash(git:*) Read'), license (a license name or file reference), and metadata (an object of string→string pairs). Returns the assembled SKILL.md to save as SKILL.md in a folder named after the skill. (In the Rokha UI the same tool fills the human's live builder form.). It is categorised as a Write tool in the Rokha MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does skill_author accept? +

skill_author accepts 7 parameters: name, license, metadata, description, instructions, allowed_tools, compatibility. Required: name, description, instructions. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on skill_author? +

Register the Rokha MCP server in PolicyLayer and add a rule for skill_author: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Rokha. Nothing to install.

What risk level is skill_author? +

skill_author is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit skill_author? +

Yes. Add a rate_limit block to the skill_author rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block skill_author completely? +

Set action: deny in the PolicyLayer policy for skill_author. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides skill_author? +

skill_author is provided by the Rokha MCP server (https://rokha.ai/mcp/jsonrpc). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
