Agent Files: Design Principles

Agent files are distilled execution context, not documentation.

IN Agent Files

• Feature IDs + one-line TL;DRs
• Interface contracts (your exports + what you receive)
• Files to create/modify
• Test IDs
• Concise TDD cycles (one line per cycle)
• Relevant gotchas (brief)
• Done checklist

OUT of Agent Files

• Verbose Gherkin (TL;DR sufficient)
• Methodology explanations (agent knows TDD)
• Git workflow (in CLAUDE.md)
• Other agents' details
• Historical context

Target Size

~200-400 lines for 2-4 features. Larger = split agent.

Searching is Failure

If agent files are well-constructed, searching plan.md is rare—only for unexpected edge cases. Frequent searching means agent files need improvement.

Workflow

Create Plan

1. Gather context → verbose plan.md
2. Map interfaces → interfaces.md
3. Draw dependencies → README.md
4. Distill agent files → agents/*.agent.md

Assign Work

Copy agents/columns.agent.md → paste to agent → done

During Execution

• Agent works from their .agent.md
• Updates status when complete
• Appends to gotchas.md if issues found
• Searches only for unexpected edge cases

Status Values

Commands

update-feature-plan

Handles mid-flight changes:

1. Apply feedback to verbose planning docs
2. Identify cascade - interface changes affect downstream agents
3. Regenerate affected agent files (distill, don't patch)
4. Verify consistency across all files

Key insight: Interface changes cascade. If #2's export changes, all agents that receive from #2 need regenerated files.

migrate-feature-plan

Converts v1.x plans (with parallelization.md, speed_prompts.md, YAML front matter) to v2.0.0:

1. Extract interfaces from YAML → interfaces.md
2. Extract gotchas → gotchas.md
3. Distill agent files from plan + parallelization → agents/*.agent.md
4. Archive old files (parallelization.md, speed_prompts.md)

Smart Orchestration

After a PR is merged, use just work to:

1. Auto-detect plan from last merged PR (title, branch, description, files)
2. Assess status of all agents (completed, active, needs cleanup)
3. Identify cleanup (completed agents not moved to completed/)
4. Determine next task using scoring algorithm (dependencies, workload, priority)
5. Provide recommendations with clickable links to plan files

Use just heal to:

• Auto-move completed agents to completed/ directory
• Detect stuck agents (WIP for 7+ days)
• Identify dependency bottlenecks
• Learn from patterns and suggest improvements

All commands support --auto flag to auto-detect plan from last PR:

• just next-task --auto
• just assess-agents --auto
• just run-agent --auto

close-feature-agent

Lightweight checkpoint:

1. Verify - Files exist, exports match, tests pass
2. Sync - Update README.md status matrix
3. Report - Show newly-unblocked features
4. Capture - Sync gotchas to gotchas.md

Does NOT regenerate agent files (use update-feature-plan for that).

Workflow Entry Points

See workflow.md for complete workflow documentation including:

• System overview (plan, agent, feature, status concepts)
• Workflow states and transitions
• Command decision tree
• When to use each command
• Common patterns and anti-patterns
• Troubleshooting guide

Quick Reference: When to Use Which Command

Primary Entry Point:

• /work - After PR merge, starting work session, need status overview

Focused Entry Points:

• /run-agent <plan> or /run-agent --auto - Ready to start working, auto-selects next best agent
• /plan-list-agents <plan> - Want to see all agents and choose which one to run
• /plan-cleanup or /heal - Cleanup needed, want to auto-fix
• /plan-check-status or /assess-agents <plan> - Need detailed status, troubleshooting
• /list-feature-plans - Need to find a plan

After Work:

• /close-feature-agent <agent-path> - Verify completion, sync status

Plan Management:

• /create-feature-plan - Create new plan
• /update-feature-plan <plan> - Modify existing plan
• /list-feature-plans - List all plans

Key Principles

1. Planning is cheap - Be verbose, iterate
2. Execution context is precious - Minimal, dense
3. Distill, don't copy - Agent files are refined extracts
4. Interfaces are boundaries - Clear contracts enable parallelism
5. One agent, one file - Coherent context, no mental merging
6. Close the loop - Verify completion before moving on
