AI agents use ccboot_create_skill to create or modify resources in Ccboot. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call ccboot_create_skill repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Ccboot.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Scaffolds a production-ready skill in .claude/skills/<name>/ with SKILL.md containing valid YAML frontmatter. Skills are reusable AI capabilities — code review, test generation, documentation, security scanning, etc. The YAML frontmatter controls behavior: • invocation: 'user' (slash command), 'auto' (triggered by context), 'both' • context: 'inline' (runs in main session), 'fork' (runs in subagent) • allowed_tools: restricts which tools the skill can use Examples: ccboot_create_skill({ name: 'code-review', description: 'Reviews code changes for quality and security', invocation: 'auto', context: 'fork', allowed_tools: ['Read', 'Grep', 'Glob'] }) ccboot_create_skill({ name: 'db-migrate', description: 'Generates and applies database migrations', invocation: 'user', context: 'inline', allowed_tools: ['Read', 'Write', 'Bash'] }) Returns: Skill location, frontmatter summary, next steps. Error: If skill name already exists (suggests different name).. It is categorised as a Write tool in the Ccboot MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Ccboot MCP server in PolicyLayer and add a rule for ccboot_create_skill: 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 Ccboot. Nothing to install.
ccboot_create_skill is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the ccboot_create_skill 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.
Set action: deny in the PolicyLayer policy for ccboot_create_skill. 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.
ccboot_create_skill is provided by the Ccboot MCP server (ccboot-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
