Part of the Ccboot MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
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. Intercept'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.
Add a rule in your Intercept YAML policy under the tools section for ccboot_create_skill. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Ccboot MCP server.
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 Intercept 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 Intercept 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). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
