/run-plan

Execute the plan at {{plan_path}} using intelligent segmentation for optimal quality.

Process:

1. Verify plan exists and is unexecuted:

   • Read {{plan_path}}
   • Check if corresponding SUMMARY.md exists in same directory
   • If SUMMARY exists: inform user plan already executed, ask if they want to re-run
   • If plan doesn't exist: error and exit

2. Parse plan and determine execution strategy:

   • Extract <objective>, <execution_context>, <context>, <tasks>, <verification>, <success_criteria> sections
   • Analyze checkpoint structure: grep "type=\"checkpoint" {{plan_path}}
   • Determine routing strategy:

   Strategy A: Fully Autonomous (no checkpoints)

   • Spawn single subagent to execute entire plan
   • Subagent reads plan, executes all tasks, creates SUMMARY, commits
   • Main context: Orchestration only (~5% usage)
   • Go to step 3A

   Strategy B: Segmented Execution (has verify-only checkpoints)

   • Parse into segments separated by checkpoints
   • Check if checkpoints are verify-only (checkpoint:human-verify)
   • If all checkpoints are verify-only: segment execution enabled
   • Go to step 3B

   Strategy C: Decision-Dependent (has decision/action checkpoints)

   • Has checkpoint:decision or checkpoint:human-action checkpoints
   • Following tasks depend on checkpoint outcomes
   • Must execute sequentially in main context
   • Go to step 3C

3. Execute based on strategy:

   3A: Fully Autonomous Execution

   Spawn Task tool (subagent_type="general-purpose"):
   
   Prompt: "Execute plan at {{plan_path}}
   
   This is a fully autonomous plan (no checkpoints).
   
   - Read the plan for full objective, context, and tasks
   - Execute ALL tasks sequentially
   - Follow all deviation rules and authentication gate protocols
   - Create SUMMARY.md in same directory as PLAN.md
   - Update ROADMAP.md plan count
   - Commit with format: feat({phase}-{plan}): [summary]
   - Report: tasks completed, files modified, commit hash"
   
   Wait for completion → Done
   

   3B: Segmented Execution (verify-only checkpoints)

   For each segment (autonomous block between checkpoints):
   
     IF segment is autonomous:
       Spawn subagent:
         "Execute tasks [X-Y] from {{plan_path}}
          Read plan for context and deviation rules.
          DO NOT create SUMMARY or commit.
          Report: tasks done, files modified, deviations"
   
       Wait for subagent completion
       Capture results
   
     ELSE IF task is checkpoint:
       Execute in main context:
         - Load checkpoint task details
         - Present checkpoint to user (action/verify/decision)
         - Wait for user response
         - Continue to next segment
   
   After all segments complete:
     - Aggregate results from all segments
     - Create SUMMARY.md with aggregated data
     - Update ROADMAP.md
     - Commit all changes
     - Done
   

   3C: Decision-Dependent Execution

   Execute in main context:
   
   Read execution context from plan <execution_context> section
   Read domain context from plan <context> section
   
   For each task in <tasks>:
     IF type="auto": execute in main, track deviations
     IF type="checkpoint:*": execute in main, wait for user
   
   After all tasks:
     - Create SUMMARY.md
     - Update ROADMAP.md
     - Commit
     - Done
   

4. Summary and completion:

   • Verify SUMMARY.md created
   • Verify commit successful
   • Present completion message with next steps

Critical Rules:

• Read execution_context first: Always load files from <execution_context> section before executing
• Minimal context loading: Only read files explicitly mentioned in <execution_context> and <context> sections
• No skill invocation: Execute directly using native tools - don't invoke create-plans skill
• All deviations tracked: Apply deviation rules from execute-phase.md, document everything in Summary
• Checkpoints are blocking: Never skip user interaction for checkpoint tasks
• Verification is mandatory: Don't mark complete without running verification checks
• Follow execute-phase.md protocol: Loaded context contains all execution instructions

Context Efficiency Target:

• Execution context: ~5-7k tokens (execute-phase.md, summary.md, checkpoints.md if needed)
• Domain context: ~10-15k tokens (BRIEF, ROADMAP, codebase files)
• Total overhead: <30% context, reserving 70%+ for workspace and implementation
