version: "1.0.1" name: autodesign description: Drive an autonomous spec-to-board PCB design with the eda-agent MCP server (Altium Designer or EasyEDA Pro). Apply when the user asks to design a board/schematic from a requirement, wants an end-to-end autonomous design run, or mentions the design harness, design_next_action, design sessions, or spec-to-board. Requires the eda-agent MCP server connected to a running Altium Designer or EasyEDA Pro; the KiCad backend does not register the design harness.

Autonomous PCB design (eda-agent)

Drive a full spec-to-board design by looping the server-side state machine. The server owns sequencing, gates, and durable state, so you never memorize the workflow: you call design_next_action, do what it says, log the result, and repeat. A weaker model produces a plainer board, never a broken pipeline, because the integrity lives server-side.

Before you start

• Confirm the editor is actually answering, with app_ping on Altium or

easyeda_ping on EasyEDA. Ping, not app_get_status: status reports that the process exists and that something once called attach, and neither of those proves the bridge replies. If it does not answer, tell the user how to start it; don't guess.

• Read design_get_discipline once: the hard rules and the DesignPlan

schema. Or call design_autonomy_guide for the full protocol + the 13 stages with their tools and exit gates.

The loop

1. design_session_start(requirement) opens the durable journal. Keep the

returned session_id; every later call takes it.

1. If a project is open or will be modified, checkpoint first so the whole

run is revertible in one step: app_checkpoint("before autonomous run") on Altium, easyeda_checkpoint on EasyEDA.

1. Loop: design_next_action(session_id) and act on status:

• proceed / retry: do the stage using its suggested_tools until the

exit_gate is met, then design_session_log(event="stage_result", stage=<stage>, status="ok"). If you cannot finish without the user, log status="blocked" with a question and stop.

• blocked: put open_question to the user; when answered,

design_session_log(event="resolved", text=<answer>) and continue.

• complete: the 13 stages are done; review outputs with the user.

1. Checkpoint again before each high-risk mutating stage: sch_to_pcb,

routing, pours_tuning.

1. Long engine runs (routing a dense board) can exceed the tool timeout;

start them with design_job_start and poll design_job_status / design_job_result.

Bounded retries: a stage that fails 3 times escalates to a human question automatically. Don't loop past it; surface it.

Resuming

A run survives context loss. In a fresh session, call design_session_resume(session_id) (or design_next_action) and pick up from recorded state: the journal, not the chat history, is the source of truth.

Hard constraints (non-negotiable)

• Datasheet-first: every device fact fetched and cited from the

manufacturer datasheet; never fabricated. Use WebSearch/WebFetch.

• NDA isolation: never mine or reference other client designs.
• No third-party routing engines or account-gated APIs in the design

loop: the in-house router is the only routing engine.

• Verify render-and-look, not by score alone; the visual rubric is the

shipping bar.

• No unverifiable safety tables: ship only sourced/verified values.

Discovering tools

The surface is 350+ tools. Use tool_catalog(category=, maturity=, interaction=, query=) to find the right one without loading every schema; interaction="modal" and "partial" flag tools that need a human or leave work incomplete. Run a discovered tool by name with tool_invoke.
