// WHEN AI AGENTS USE THIS TOOL

AI agents invoke speclock_parse_diff to trigger processes or run actions in SpecLock - AI Constraint Engine. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.

// WHY ENFORCE A POLICY ON SPECLOCK_PARSE_DIFF

speclock_parse_diff can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.

// RECOMMENDED POLICY

Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

// FAQ

What does the speclock_parse_diff tool do? +

Parse unified diff into structured changes — imports, exports, symbols, routes, schema detection.. It is categorised as a Execute tool in the SpecLock - AI Constraint Engine MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on speclock_parse_diff? +

Add a rule in your Intercept YAML policy under the tools section for speclock_parse_diff. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the SpecLock - AI Constraint Engine MCP server.

What risk level is speclock_parse_diff? +

speclock_parse_diff is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit speclock_parse_diff? +

Yes. Add a rate_limit block to the speclock_parse_diff 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.

How do I block speclock_parse_diff completely? +

Set action: deny in the Intercept policy for speclock_parse_diff. 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 speclock_parse_diff? +

speclock_parse_diff is provided by the SpecLock - AI Constraint Engine MCP server (sgroy10/speclock). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
