gigaspec-init · Gigaspec MCP: Risk & Policy

WHAT IT DOES

What gigaspec-init does on Gigaspec

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

WHY IT NEEDS A POLICY

Why gigaspec-init needs a policy

This tool creates new files and project structures on the filesystem. It is a Write operation because it creates new documents/files reversibly (files can be deleted). The blast radius is medium since it initializes a structured set of files that could overwrite existing ones if a project already exists, but it is not inherently destructive or irreversible.

From the tool's definition Initialize a new project...Creates specification files (AGENT.md, ARCHITECTURE.md, PLAN.md, STATE.md, etc.)

gigaspec-init Rate-limited

gigaspec-init 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.

Initialize a new project with AI collaboration framework. Creates specification files (AGENT.md, ARCHITECTURE.md, PLAN.md, STATE.md, etc.) based on project requirements. It is categorised as a Write tool in the Gigaspec MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on gigaspec-init? +

Register the Gigaspec MCP server in PolicyLayer and add a rule for gigaspec-init: 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 Gigaspec. Nothing to install.

What risk level is gigaspec-init? +

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

Can I rate-limit gigaspec-init? +

Yes. Add a rate_limit block to the gigaspec-init 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 gigaspec-init completely? +
