Epa Handoff Management

EPA Handoff Management Skill

Overview

This skill enables the Emasoft Programmer Agent (EPA) to create and receive handoff documents for seamless context transfer between agents and sessions. Handoff documents are structured Markdown files with YAML frontmatter that capture work state, task context, bug reports, and checkpoint data. The EPA uses this skill whenever it receives delegated work from the Emasoft Orchestrator Agent (EOA), needs to pass completed work to the Emasoft Integrator Agent (EIA), discovers bugs during implementation, or must save progress before a session ends. All handoff documents are stored under $CLAUDE_PROJECT_DIR/thoughts/shared/handoffs/ in a standardized directory structure that all agents in the ecosystem can read.

Prerequisites

Before using this skill, ensure the following conditions are met:

1. AI Maestro must be running on localhost:23000 for inter-agent messaging notifications when handoffs are created or received.
2. The handoff directory must exist at $CLAUDE_PROJECT_DIR/thoughts/shared/handoffs/. Create it with mkdir -p "$CLAUDE_PROJECT_DIR/thoughts/shared/handoffs/" if it does not exist.
3. The EPA agent must have a valid session name registered with AI Maestro (format: epa-<project>-<instance>), so that handoff notifications reach the correct recipient.
4. The $CLAUDE_PROJECT_DIR environment variable must be set to the root of the project directory. This variable is set automatically by Claude Code when a project is loaded.
5. Read access to the references directory at references/ relative to this skill, which contains the detailed operation guides for each handoff operation.

Instructions

Follow these numbered steps when performing handoff management:

1. Determine the handoff operation needed. Consult the Quick Reference table at the bottom of this document to match your current situation to the correct operation (Read, Create, Write Bug Report, or Document Work State).
2. Read the corresponding operation reference file. Each operation has a dedicated guide in the references/ directory. Read the full guide before proceeding.
3. Verify the handoff directory exists. Run mkdir -p "$CLAUDE_PROJECT_DIR/thoughts/shared/handoffs/epa-<task-name>/" to ensure the task-specific subdirectory is available.
4. Execute the operation. Follow the step-by-step procedure in the reference file. All handoff documents must include YAML frontmatter with fields: type, from, to, task, timestamp, and status.
5. Validate the handoff document. After writing, re-read the document to confirm all required fields are present and the content accurately reflects the current work state.
6. Send notification via AI Maestro. After creating or updating a handoff, send a message to the receiving agent using curl -X POST "http://localhost:23000/api/messages" with the handoff file path in the message body.
7. Archive previous versions. If updating an existing handoff, move the previous current.md to the archive/ subdirectory with a timestamp suffix before writing the new version.

Purpose

Handoff documents preserve work state across:

• Agent transitions (when EOA delegates to EPA)
• Session boundaries (when context is cleared)
• Bug discoveries (structured reporting)
• Work interruptions (save and resume)

Operations

This skill provides four core operations for handoff management:

1. Read Handoff Document

File: op-read-handoff-document.md

Contents:

• 1.1 When to read a handoff document
• 1.2 Parsing handoff YAML frontmatter
• 1.3 Extracting task context and requirements
• 1.4 Identifying delegated work items
• 1.5 Resuming from checkpoints

Use this operation when receiving work from EOA or resuming from a previous session.

2. Create Handoff Document

File: op-create-handoff-document.md

Contents:

• 2.1 When to create a handoff document
• 2.2 Handoff document structure and format
• 2.3 Capturing current work state
• 2.4 Documenting completed and pending items
• 2.5 Writing to the handoff directory

Use this operation when transferring work to another agent or ending a session.

3. Write Bug Report

File: op-write-bug-report.md

Contents:

• 3.1 When to write a bug report
• 3.2 Bug report structure and required fields
• 3.3 Capturing reproduction steps
• 3.4 Documenting expected versus actual behavior
• 3.5 Linking to related code and tests

Use this operation when discovering bugs during implementation work.

4. Document Work State

File: op-document-work-state.md

Contents:

• 4.1 When to document work state
• 4.2 Work state document structure
• 4.3 Capturing in-progress changes
• 4.4 Recording decision context
• 4.5 Enabling session resume

Use this operation to save current work for later continuation.

Handoff Directory Structure

All handoff documents are stored in a standardized location:

$CLAUDE_PROJECT_DIR/thoughts/shared/handoffs/
├── epa-<task-name>/
│   ├── current.md           # Active handoff document
│   ├── archive/             # Previous handoff versions
│   └── bugs/                # Bug reports for this task

Integration with AI Maestro

This skill integrates with AI Maestro for inter-agent messaging:

• Handoff creation triggers notification to receiving agent
• Bug reports can be escalated to EOA for triage
• Work state documents enable checkpoint-based resume

Quick Reference

Output

This skill produces the following artifacts:

• Handoff documents (current.md): Markdown files with YAML frontmatter stored at $CLAUDE_PROJECT_DIR/thoughts/shared/handoffs/epa-<task-name>/current.md. Contains task context, completed items, pending items, checkpoint state, and file references.
• Bug reports (bugs/<bug-id>.md): Structured bug reports stored in the bugs/ subdirectory of the task handoff folder. Each report includes reproduction steps, expected versus actual behavior, code references, and severity classification.
• Archived handoffs (archive/<timestamp>-current.md): Previous versions of handoff documents preserved with timestamp prefixes for audit trail and rollback capability.
• AI Maestro notifications: JSON messages sent to the receiving agent via the AI Maestro API confirming that a handoff document has been created or updated.

Checklist

Copy this checklist and track your progress:

• Determine handoff operation needed (Read, Create, Bug Report, or Document Work State)
• Read the corresponding operation reference file
• Verify handoff directory exists
• Execute the handoff operation
• Validate the handoff document (all required YAML fields present)
• Send notification via AI Maestro to receiving agent
• Archive previous version if updating an existing handoff

Error Handling

Common errors encountered during handoff management and their resolutions:

Examples

Example 1: Creating a handoff after completing implementation

The EPA has finished implementing a feature and needs to pass it to EIA for code review:

---
type: handoff
from: epa-svgbbox-programmer-001
to: eia-svgbbox-reviewer
task: implement-bbox-calculation
timestamp: 2026-02-14T10:30:00Z
status: implementation-complete
---

# Handoff: implement-bbox-calculation

## Completed Items
- Implemented `calculate_bbox()` function in `src/bbox/calculator.py`
- Added unit tests in `tests/unit/test_calculator.py` (12 tests, all passing)
- Updated type annotations and docstrings

## Files Modified
- `src/bbox/calculator.py` (new file, 145 lines)
- `tests/unit/test_calculator.py` (new file, 210 lines)

## Pending Items
- Code review by EIA
- Integration test with SVG parser module

## Notes
- Used numpy for matrix operations as specified in architecture doc
- Edge case: zero-dimension bounding boxes return empty BBox object (see test_empty_bbox)

After writing this to $CLAUDE_PROJECT_DIR/thoughts/shared/handoffs/epa-implement-bbox-calculation/current.md, send a notification:

curl -X POST "http://localhost:23000/api/messages" \
  -H "Content-Type: application/json" \
  -d '{"to": "eia-svgbbox-reviewer", "subject": "Handoff ready: implement-bbox-calculation", "priority": "normal", "content": {"type": "handoff", "message": "Implementation complete. Handoff at thoughts/shared/handoffs/epa-implement-bbox-calculation/current.md"}}'

Example 2: Receiving a delegation handoff from EOA

The EPA receives a message from EOA with a task delegation. The first step is to read the handoff:

# 1. Read the handoff document
cat "$CLAUDE_PROJECT_DIR/thoughts/shared/handoffs/eoa-refactor-parser/current.md"

# 2. Extract key fields from YAML frontmatter
# Look for: task, requirements, deadline, dependencies, checkpoint (if resuming)

# 3. Acknowledge receipt via AI Maestro
curl -X POST "http://localhost:23000/api/messages" \
  -H "Content-Type: application/json" \
  -d '{"to": "eoa-svgbbox-orchestrator", "subject": "Handoff received: refactor-parser", "priority": "normal", "content": {"type": "acknowledgment", "message": "EPA received handoff for refactor-parser. Starting work."}}'

Example 3: Writing a bug report discovered during implementation

While working on a feature, the EPA discovers a bug in an existing module:

---
type: bug-report
from: epa-svgbbox-programmer-001
task: implement-bbox-calculation
bug-id: BUG-2026-0214-001
severity: high
timestamp: 2026-02-14T11:15:00Z
---

# Bug Report: SVG path parser returns incorrect coordinates for arc commands

## Reproduction Steps
1. Load `tests/fixtures/arc-path.svg`
2. Call `parse_path(svg_content)` from `src/parser/path_parser.py`
3. Inspect the returned coordinate list for arc (`A`) commands

## Expected Behavior
Arc command coordinates should be absolute after conversion from relative coordinates.

## Actual Behavior
Arc commands retain relative coordinates, causing bbox calculation to be offset by the current pen position.

## Affected Code
- `src/parser/path_parser.py`, function `_parse_arc_command()`, line 87-102

## Related Tests
- `tests/unit/test_path_parser.py::test_arc_absolute_coords` (currently failing)

Save this to $CLAUDE_PROJECT_DIR/thoughts/shared/handoffs/epa-implement-bbox-calculation/bugs/BUG-2026-0214-001.md and escalate to EOA for triage.
