Proposal Skill

This skill covers the Planning stage of the AI-DLC workflow: creating Proposals that contain document drafts (PRD, tech design) and task drafts with dependency DAGs, then submitting them for Admin review.

Overview

After an Idea's elaboration is resolved (see idea-chorus skill at <BASE_URL>/skill/idea-chorus/SKILL.md), the PM Agent creates a Proposal — a container that holds document drafts and task drafts. On Admin approval, these drafts materialize into real Documents and Tasks.

Elaboration resolved --> Create Proposal --> Add drafts --> Validate --> Submit --> Admin review

Workflow

Step 1: Create an Empty Proposal

It is generally best to create the proposal container first without any drafts, then incrementally add document and task drafts one by one.

chorus_pm_create_proposal({
  projectUuid: "<project-uuid>",
  title: "Implement <feature name>",
  description: "Analysis and implementation plan for Idea #xxx",
  inputType: "idea",
  inputUuids: ["<idea-uuid>"]
})

Multiple Ideas: You can combine multiple ideas into one proposal by passing multiple UUIDs in inputUuids.

Step 2: Add Document Drafts

Add document drafts one at a time:

# Add PRD
chorus_pm_add_document_draft({
  proposalUuid: "<proposal-uuid>",
  type: "prd",
  title: "PRD: <Feature Name>",
  content: "# PRD: <Feature Name>\n\n## Background\n...\n## Requirements\n..."
})

# Add Tech Design
chorus_pm_add_document_draft({
  proposalUuid: "<proposal-uuid>",
  type: "tech_design",
  title: "Tech Design: <Feature Name>",
  content: "# Technical Design\n\n## Architecture\n...\n## Implementation\n..."
})

Document types: prd, tech_design, adr, spec, guide

Step 3: Add Task Drafts

Add task drafts one at a time. The response returns the new draft's draftUuid — use it directly for dependsOnDraftUuids in subsequent drafts.

# First task -> response includes { draftUuid, draftTitle }
chorus_pm_add_task_draft({
  proposalUuid: "<proposal-uuid>",
  title: "Implement <component>",
  description: "Detailed description of what to build...",
  priority: "high",
  storyPoints: 3,
  acceptanceCriteria: "- [ ] Criteria 1\n- [ ] Criteria 2"
})

# Second task — depends on first
chorus_pm_add_task_draft({
  proposalUuid: "<proposal-uuid>",
  title: "Write tests for <component>",
  description: "Unit and integration tests...",
  priority: "medium",
  storyPoints: 2,
  acceptanceCriteria: "- [ ] Test coverage > 80%",
  dependsOnDraftUuids: ["<draftUuid-from-first-task>"]
})

Task priority: low, medium, high

Step 4: Review and Refine Drafts

# Review current state
chorus_get_proposal({ proposalUuid: "<proposal-uuid>" })

# Update a document draft
chorus_pm_update_document_draft({
  proposalUuid: "<proposal-uuid>",
  draftUuid: "<draft-uuid>",
  content: "Updated content..."
})

# Update a task draft
chorus_pm_update_task_draft({
  proposalUuid: "<proposal-uuid>",
  draftUuid: "<draft-uuid>",
  description: "Updated description...",
  dependsOnDraftUuids: ["<other-draft-uuid>"]
})

# Remove a draft
chorus_pm_remove_task_draft({
  proposalUuid: "<proposal-uuid>",
  draftUuid: "<draft-uuid>"
})

Step 5: Validate and Submit

Before submitting, validate to preview issues:

chorus_pm_validate_proposal({ proposalUuid: "<proposal-uuid>" })

Returns { valid, issues } with error, warning, and info levels. Fix errors before submitting.

When validation passes:

chorus_pm_submit_proposal({ proposalUuid: "<proposal-uuid>" })

This changes the status from draft to pending. An Admin will review it (see review-chorus skill at <BASE_URL>/skill/review-chorus/SKILL.md).

Consider adding a comment explaining your reasoning:

chorus_add_comment({
  targetType: "proposal",
  targetUuid: "<proposal-uuid>",
  content: "This proposal covers... Key decisions: ..."
})

Step 6: Handle Feedback

If the proposal is rejected, check the review note:

chorus_get_proposal({ proposalUuid: "<proposal-uuid>" })
chorus_get_comments({ targetType: "proposal", targetUuid: "<proposal-uuid>" })

Revise the drafts and resubmit.

Step 7: Post-Approval

When the Admin approves:

• Document drafts become real Documents
• Task drafts become real Tasks (status: open, ready for developers)
• The Idea's displayed status is automatically derived from Proposal and Task progress -- no manual update needed

Step 8: Manage Task Dependencies (Optional)

After tasks are created, you can manage dependencies:

Batch create tasks with intra-batch dependencies:

chorus_pm_create_tasks({
  projectUuid: "<project-uuid>",
  tasks: [
    { draftUuid: "draft-db", title: "Create database schema", priority: "high", storyPoints: 2 },
    { draftUuid: "draft-api", title: "Implement API endpoints", priority: "high", storyPoints: 4, dependsOnDraftUuids: ["draft-db"] },
    { title: "Write integration tests", priority: "medium", storyPoints: 2, dependsOnDraftUuids: ["draft-api"] }
  ]
})

Add/remove dependencies on existing tasks:

chorus_add_task_dependency({ taskUuid: "<task-B-uuid>", dependsOnTaskUuid: "<task-A-uuid>" })
chorus_remove_task_dependency({ taskUuid: "<task-B-uuid>", dependsOnTaskUuid: "<task-A-uuid>" })

Dependencies are validated: same project, no self-dependency, no cycles (DFS detection).

Step 9: Assign Tasks to Developer Agents (Optional)

chorus_pm_assign_task({ taskUuid: "<task-uuid>", agentUuid: "<developer-agent-uuid>" })

• Task should be open or assigned
• Target agent should have developer or developer_agent role

Document Writing Guidelines

PRD Structure

# PRD: <Feature Name>

## Background
Why this feature is needed.

## Requirements
### Functional Requirements
- FR-1: ...

### Non-Functional Requirements
- NFR-1: ...

## User Stories
- As a <role>, I want <action>, so that <benefit>

## Out of Scope
What is NOT included.

Tech Design Structure

# Technical Design: <Feature Name>

## Overview
High-level approach.

## Architecture
System design, component interactions.

## Data Model
Schema changes, new tables.

## API Design
New/modified endpoints.

## Module Contracts
Shared conventions across tasks: return value format, error handling pattern, cross-module call points.

## Implementation Plan
Step-by-step implementation order.

## Risks & Mitigations
Potential issues and how to address them.

Task Writing Guidelines

Good tasks are:

• Module-scoped — One cohesive functional module per task, not a single function or file
• Testable — Clear, cohesive acceptance criteria (max 6 items per task; group related checks into one criterion but list key coverage, e.g. "All tests pass: service layer unit tests, API integration tests, edge case handling")
• Sized — 1-8 story points (hours of agent work)
• Ordered — Use dependsOnDraftUuids / dependsOnTaskUuids to express execution order
• Descriptive — Include enough context for a developer agent to start without questions. For tasks with cross-module dependencies, reference the tech design's Module Contracts in the AC

Task Granularity

Each task should correspond to an independently runnable and testable functional module — not a single function, file, or API endpoint. Avoid splitting closely related functionality into separate tasks; the Chorus workflow overhead per task (claim → implement → self-test → submit → verify) adds up quickly.

Bad → Good examples:

• Bad: Book Search + Book CRUD (2 tasks) → Good: Book Management (1 task covering CRUD + Search for the same entity)
• Bad: Chart Rendering + Statistics Calculation (2 tasks) → Good: Data Analytics (1 task covering stats + visualization as one module)

Tips

• Keep PRD focused on what and why; tech design focused on how
• Break large features into cohesive module-scoped tasks — but avoid over-splitting related functionality into too many tiny tasks
• Add storyPoints to help prioritize and estimate effort
• Keep acceptance criteria cohesive — group related verifications into one item rather than listing each check separately
• Prefer setting up task dependency DAG — tasks without dependencies are assumed parallelizable
• When multiple tasks share data formats or call each other, define contracts in the tech design before writing task AC
• When combining multiple ideas, consider explaining how they relate in the proposal description
