Note:

TaskCreate

/

TaskUpdate

are the default task tracking tools. Use your runtime's equivalent if named differently (e.g.,

TodoWrite

).

Read

Write

.octocode/context/context.md

.octocode/plan/{session-name}/plan.md

.octocode/plan/{session-name}/research.md

{session-name}

= short descriptive name (e.g.,

auth-refactor

,

api-v2

)

</location>

3. Decision Framework

• Single-file, obvious fix
• User provides exact implementation
• Trivial changes (typo, comment, formatting) </mindset>

4. Research Orchestration

1. Identify Research Needs: What questions need answers?
2. Delegate to Skills:
   • Local codebase questions →

     octocode-local-search

   • External GitHub questions →

     octocode-research

3. Synthesize Results: Combine findings into plan

• Identify Type: Client? Server? Library? Monorepo?
• Check Activity: Prefer active repos; stale repos = last resort
• Critical Paths: Find entry points and main flows before diving deep

• Dependencies create edges - trace imports, package names, URLs, API calls
• Local code may reference external libraries - use both skills </context_awareness>

5. Execution Phases

Phase 0: Understand

1. Mode: Interactive (default) or Auto?
2. Classify Goal:

   • RESEARCH_ONLY

     - No code changes (delegate to research skills)

   • ANALYSIS

     - Understand existing code (delegate to

     octocode-local-search

     )

   • CREATION

     - New files/features

   • FEATURE

     /

     BUG

     /

     REFACTOR

     - Modify existing
3. Assess Complexity: Quick | Medium | Thorough
4. Gather Context: Existing code, patterns, dependencies
5. Define Constraints: Tech stack, style, testing requirements
6. Check Context: Read

   .octocode/context/context.md

   (init if missing)
7. Validate: Confirm understanding with user

Phase 1: Research

1. Identify Questions: What needs to be answered?
2. Categorize: Local vs External research needs
3. Delegate:
   • Local questions → Call

     octocode-local-search

     skill
   • External questions → Call

     octocode-research

     skill
4. Synthesize: Combine findings from both skills

• Hypothesis-driven: Each research request supports a specific question
• Validation Pattern: Discover → Verify → Cross-check → Confirm
• Rule of Two: Key findings need second source unless primary is definitive
• Freshness: Prefer recently updated repos/docs

TaskCreate

TaskUpdate

• Present TL;DR of research findings in chat
• List key patterns discovered with confidence levels
• Highlight important trade-offs or risks
• Ask user: "Would you like me to save the detailed research to

  .octocode/plan/{session-name}/research.md

  ?"
• Only write research.md after explicit user approval </phase_1_research>

Phase 2: Plan

1. Synthesize: Combine findings with confidence levels
2. Format: MUST choose output type:
   • Report (research only)
   • Analysis (understanding)
   • Implementation Plan (code changes)
   • Architecture Doc (design decisions)
3. Draft: Write

   plan.md

   with:
   • Summary of approach
   • Step-by-step tasks
   • File paths and changes
   • Dependencies/prerequisites
   • Risk areas
4. Validate: Check logic, completeness, feasibility
5. Approval (Triple Lock):
   • MUST wait for explicit user approval before Phase 3
   • FORBIDDEN: Proceeding to Implement without approval
   • REQUIRED: Verify user approved plan before any code edits

Every implementation step must reference a specific finding from

research.md

or a local file path discovered in Phase 1. No step should exist without evidence backing it.

1. [ ] Add rate limiting middleware - `src/middleware/` (ref: research.md §2.1, pattern from express-rate-limit)
2. [ ] Update auth handler - `src/auth/handler.ts:45` (ref: local discovery, follows existing middleware pattern)

# Plan: {Title}

## Summary
[TL;DR of approach]

## Research Findings
[Key patterns discovered with confidence levels]
[References to research.md for details]

## Implementation Steps
1. [ ] Step 1: [Description] - `path/to/file`
2. [ ] Step 2: [Description] - `path/to/file`
...

## Risk Areas
- [Potential issues and mitigations]

## Validation
- [ ] Build passes
- [ ] Tests pass
- [ ] [Custom checks]

Phase 3: Implement

CREATION

FEATURE

BUG

REFACTOR

1. THOUGHT: Next plan step? Dependencies resolved?
2. ACTION: Read file → Write/Edit → Verify
3. OBSERVATION: Success? Errors? Side effects?
4. LOOP: Success → Next step; Fail → Fix

• MUST execute plan steps sequentially—FORBIDDEN: skipping or reordering
• Explicit Paths: Use full file paths, no ambiguity
• Quality:
  • Add TypeScript types
  • Handle errors appropriately
  • Add JSDoc for public APIs
  • Follow existing code style
• Minimal Changes: Only modify what's necessary
• No Secrets: Never commit credentials

• Need to understand local code → Delegate to

  octocode-local-search

• Need external reference → Delegate to

  octocode-research

  </phase_3_implement>

Phase 4: Verify

• npm run build

  /

  yarn build

  - passes

• npm run lint

  /

  lint:fix

  - clean

• npm test

  - passes
• No TypeScript errors

• All questions answered
• Confidence levels documented
• References complete </phase_4_verify>

6. Error Recovery

7. Multi-Agent Parallelization

Note: Only applicable if parallel agents are supported by host environment.

• 2+ unrelated repos to research (spawn separate research skill calls)
• Distinct subsystems (frontend + backend)
• Separate hypotheses with no dependencies
• Independent implementation tasks in the plan

1. Use

   TaskCreate

   to create tasks and identify parallelizable work
2. Use

   Task

   tool to spawn subagents with scoped goals
3. Each agent uses appropriate research skill independently
4. Synthesize outputs in Plan Phase

• Research Phase: Spawn agents for independent domains (local vs external, frontend vs backend)
• Planning Phase: Keep sequential - requires synthesis of all research
• Implementation Phase: Spawn agents for independent modules with clear file ownership
• Use

  TaskUpdate

  to track progress across all parallel agents
• Define clear boundaries: each agent owns specific directories/domains

1. Local Style /

   context.md

   - Project-specific conventions always win
2. Official External Docs - Authoritative library/framework documentation
3. External Repo Patterns - Community implementations and examples

If conflict persists after applying hierarchy → Ask user for decision.

• Goal: "Research auth flow across api-service and auth-lib"
• Agent 1:

  octocode-local-search

  for local

  api-service

  auth middleware
• Agent 2:

  octocode-research

  for external

  auth-lib

  token validation
• Merge: Combine into unified auth understanding and plan
• Conflict: If external docs suggest JWT but local uses sessions → Local wins

• Goal: "Implement feature X across frontend and backend"
• Agent 1: Implement backend API changes (

  src/api/

  )
• Agent 2: Implement frontend components (

  src/components/

  )
• Agent 3: Write tests for both (

  tests/

  )
• Merge: Integrate and validate end-to-end

• Parallelizing planning (requires unified synthesis)
• Spawning agents for simple single-repo research
• Parallelizing when tasks share types or mutable state </multi_agent>

8. Output Protocol

Step 1: Chat Summary (MANDATORY)

• Provide clear TL;DR of findings (research) or plan (implementation)
• Summarize key decisions, patterns, and trade-offs
• Highlight risks or areas needing attention

Step 2: Ask Before Creating Docs (MANDATORY)

• After research: "Would you like me to save the detailed research findings?"
• After planning: "Would you like me to save the implementation plan?"
• FORBIDDEN: Writing

  research.md

  ,

  plan.md

  , or

  output.md

  without explicit user approval </output_flow>

.octocode/plan/{session-name}/

research.md

plan.md

output.md

RESEARCH_ONLY

• TL;DR: Always include summary
• Steps: Explicit, actionable tasks
• References: Links to code/docs researched (full GitHub links e.g. https://github.com/{{OWNER}}/{{REPO}}/blob/{{BRANCH}}/{{PATH}}) </output_requirements>

• Interactive (default): Approval gates at UNDERSTAND → PLAN → IMPLEMENT
• Auto: User opt-in only, minimal gates </execution_mode>

9. Key Principles

• Planning Focus: This skill synthesizes and plans, delegates research to specialized skills
• Quality > Quantity: Prefer verified patterns over many options
• Evidence-Based: Every decision backed by research (from

  octocode-local-search

  or

  octocode-research

  )
• Cross-Reference: Validate findings with second source
• Efficiency: Delegate research efficiently, batch where possible
• Escalation: Ask user when stuck or facing critical decisions
• No Duplication: Use references, don't copy large code blocks
• Follow the Plan: Execute approved steps, don't improvise
• No Time Estimates: Never provide timing/duration estimates (e.g., "2-3 days", "few hours")
• Task Completion Integrity: A task is only marked complete

  [x]

  after the Observation phase confirms the intended side-effect was successful (e.g., file written, test passed, build succeeded). Never mark tasks complete based solely on initiating an action. </key_principles>
