AI agents call cost-phase to retrieve information from Kit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and correlates cost/usage data from existing files (SPEC.md, STATE.md) and git log to infer a temporal window and return cost information. It performs no writes, executions, or destructive actions — purely a read/query operation with reporting output.
From the tool's definition 'Custo Claude Code correlacionado com uma fase' — correlates/reads cost data for a framework phase; 'Cruza mtime de SPEC.md + completed_at de STATE.md + git log para inferir janela temporal' — reads file metadata and git log; 'Retorna shape canônico +…

Custo Claude Code correlacionado com uma fase do framework kit-mcp (.planning/phases/<id>-*/). Cruza mtime de SPEC.md + completed_at de STATE.md + git log para inferir janela temporal. Retorna shape canônico + phase_id, phase_slug, correlation_confidence (high/medium/low/unknown). Diferencial vs ccusage: contexto de workflow. Triggers:. It is categorised as a Read tool in the Kit MCP Server, which means it retrieves data without modifying state.
Register the Kit MCP server in PolicyLayer and add a rule for cost-phase: 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 Kit. Nothing to install.
cost-phase is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the cost-phase 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 cost-phase. 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.
cost-phase is provided by the Kit MCP server (luanpdd/kit-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
