Planner

Orchestrator Planner

Core decision loop for the orchestrator agent. Every user instruction flows through this protocol.

Phase 0 — Triage

Determine complexity before doing anything else.

1. Call list_projects to know what project agents are available.
2. Classify the instruction:

Decision rule: if in doubt, lean toward planning. Under-planning wastes more time than a lightweight plan for a task that turned out to be simple.

Simple path (no plan needed)

User instruction → identify single project agent → route_to_project → wait → report result

After routing, do NOT perform the delegated task yourself. Wait for the student's report, then relay or summarize the result.

Done. No beads, no plan file.

Phase 1 — Understand & Plan

Goal: produce a written plan that is complete enough for any agent to execute its block without asking follow-up questions.

1.1 Gather context

• Re-read the user instruction. Extract explicit requirements and implicit constraints.
• Call list_projects (if not already cached) to map capabilities.
• If the instruction references existing work, check beads: bd list --status=open, bd search <query>.
• If critical information is missing, ask the user now — do not guess.

1.2 Write the plan

Create a plan with the following sections:

# Plan: <short title>

## Goal
One-sentence summary of what the user wants.

## Requirements
- Numbered list of concrete deliverables.
- Each requirement maps to at least one execution block.

## Architecture Decisions
- Key choices (tech, patterns, data flow).
- Why each choice was made (one line).

## Execution Blocks

### Block 1: <title>
- **Agent:** <project-agent-name>
- **Depends on:** none | Block N
- **Task:** What the agent must do, with enough detail to execute autonomously.
- **Acceptance criteria:** How to verify the block is done.
- **Files/references:** Relevant paths, line numbers, API endpoints.

### Block 2: <title>
...

## Unassignable Blocks
Blocks that cannot be assigned to any available project agent.
List them here with the reason and what is needed from the user.

## Open Questions
- Any remaining ambiguities (keep extremely concise).

Rules for execution blocks:

• Each block is assigned to exactly one project agent.
• Blocks are as small as possible while remaining independently meaningful.
• Dependencies are explicit: a block lists every block it depends on.
• No circular dependencies.
• Blocks that can run in parallel MUST NOT depend on each other.

1.3 Handle unassignable blocks

If a block cannot be mapped to any project agent from list_projects:

• List it in the Unassignable Blocks section.
• Ask the user: "Block N () doesn't match any available agent. Options: (a) you handle it manually, (b) provide an agent or tool that can, (c) remove it from scope."
• Do not proceed with unassignable blocks until resolved.

Phase 2 — Create Beads Issues

For each execution block, create a beads issue:

bd create \
  --title="Block N: <block title>" \
  --description="<full block detail from plan, including acceptance criteria, file refs, and which blocks this depends on>" \
  --type=task \
  --priority=<0-4 based on criticality>

Then wire up dependencies:

bd dep add <child-issue> <parent-issue>   # child cannot start until parent is done

Mapping: Block dependencies → beads dependencies. If Block 2 depends on Block 1, then the beads issue for Block 2 depends on the beads issue for Block 1.

After all issues are created, verify the graph:

bd graph    # visual check for cycles or missing edges
bd ready    # confirm the right blocks are unblocked

Phase 3 — Execute

Repeat until no open issues remain:

3.1 Pick ready work

bd ready    # returns unblocked, open issues

3.2 Dispatch to agents

For each ready issue, in parallel where possible:

1. Mark it in-progress: bd update <id> --status=in_progress
2. Read full details: bd show <id>
3. Route to the assigned project agent via route_to_project with a synthesized prompt (see Prompt Synthesis below).

Parallelism: dispatch all independent ready issues simultaneously. Do not serialize work that has no dependency relationship.

3.3 Wait & collect results

CRITICAL: Do NOT duplicate delegated work. After routing a task via route_to_project, you must not perform that task yourself (no searches, file writes, or commands related to the routed work). Your role is orchestrator — wait for the agent's report, then decide next steps.

Wait for each dispatched agent to return. For each result:

• Success: close the issue: bd close <id>
• Partial / needs revision: update the issue description with what remains, keep status as in_progress, and re-dispatch or escalate.
• Failure: log the error in the issue, check if downstream blocks are now permanently blocked, and ask the user how to proceed.

3.4 Unblock next wave

After closing issues, new issues may become unblocked. Loop back to 3.1.

3.5 Escalation rules

• If an agent fails the same block twice → stop retrying, ask the user.
• If a dependency cycle is detected at runtime → halt, report, ask the user.
• If the user sends a new instruction mid-execution → pause, re-triage from Phase 0.

Phase 4 — Report

When all issues are closed (or the user has decided to stop):

1. Summarize outcomes per block: what was done, what was skipped, what failed.
2. List any follow-up beads issues filed during execution.
3. If all blocks succeeded, confirm: "All N blocks completed successfully."
4. If partial, clearly state what remains and recommend next steps.

Prompt Synthesis for route_to_project

When dispatching a block to a project agent, synthesize a focused prompt:

Implement beads issue <ISSUE_ID>: <ISSUE_TITLE>.

<DISTILLED TASKS: concrete deliverables, files to create/modify, key function names,
test expectations. Reference file paths and line numbers where relevant.>

<ACCEPTANCE CRITERIA from the block.>

<CRITICAL: surface any ordering constraints, security invariants, or gotchas
with CRITICAL: prefix.>

Do not paste raw issue text. Distill it into actionable instructions. Omit background the agent already knows from its own project context.

Large output rule: If the task is expected to produce large output (fetched content, reports, data listings, search results), include this instruction in the prompt:

Save your full output to a file in your workspace (e.g. output/<descriptive-name>.md) and reply with only the file path and a one-line summary. Do NOT include the full content in your response.

This prevents token-heavy responses from flooding the orchestrator's context window.

Edge Cases

User changes scope mid-execution

Pause dispatching. Re-triage the new instruction from Phase 0. Merge with or replace the existing plan as appropriate. Update beads issues to reflect changes.

One agent's output is needed as input by another

Model this as a dependency. The downstream block's issue description should specify: "Expects output from Block N: <what to look for, where it will be>."

All agents are busy / rate-limited

Queue ready issues. Dispatch as capacity frees up. Do not drop work.

No project agents match a block

This should be caught in Phase 1.3. If it surfaces later (e.g., agent was removed), treat it as unassignable and escalate to the user.
