Generate a token-budgeted project brief for system prompt injection. Returns gotchas, conventions, architecture, and decisions — prioritized by importance. Use this ONCE at session start instead of calling recall/conventions/architecture individually.
AI agents call project_brief to retrieve information from Tages without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and aggregates stored project context (architecture, conventions, decisions) for injection into a session prompt. It is purely a read/query operation with no side effects — it generates a summary from existing stored data without creating, modifying, or deleting anything.
From the tool's definition Generate a token-budgeted project brief... Returns gotchas, conventions, architecture, and decisions — prioritized by importance. Use this ONCE at session start instead of calling recall/conventions/architecture individually.

Generate a token-budgeted project brief for system prompt injection. Returns gotchas, conventions, architecture, and decisions — prioritized by importance. Use this ONCE at session start instead of calling recall/conventions/architecture individually. It is categorised as a Read tool in the Tages MCP Server, which means it retrieves data without modifying state.
Register the Tages MCP server in PolicyLayer and add a rule for project_brief: 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 Tages. Nothing to install.
project_brief 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 project_brief 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 project_brief. 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.
project_brief is provided by the Tages MCP server (ryantlee25-droid/tages). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
