plan-inlineSafety 95Repository ShareFavorite skill

Create a TDD implementation plan directly from inline instructions in $ARGUMENTS.

Purpose

• Convert inline task descriptions into actionable TDD implementation plans
• Skip the TODO.md intermediary when task is already well-defined
• Explore codebase to understand existing patterns and find relevant files
• Use MCPs to gather additional context (Drive files, spreadsheets, deployments)
• Generate detailed, implementable plans with full file paths

When to Use

Use plan-inline instead of plan-todo when:

• The user provides a clear feature request or task description directly
• The task doesn't need to be tracked in TODO.md backlog
• Quick planning without backlog management overhead

Use plan-todo instead when:

• Working from existing backlog items
• Managing multiple items that should be tracked

Pre-flight Check

Before doing anything, read PLANS.md and check for incomplete work:

• If PLANS.md has content but NO "Status: COMPLETE" at the end → STOP
• Tell the user: "PLANS.md has incomplete work. Please review and clear it before planning new items."
• Do not proceed.

If PLANS.md is empty or has "Status: COMPLETE" → proceed with planning.

Arguments

$ARGUMENTS should contain the task description with context:

• What to implement or change
• Expected behavior
• Any constraints or requirements
• Related files if known

Example arguments:

• Add a function to validate CUIT numbers with modulo 11 algorithm
• Create a new route /api/retry that retries failed documents
• Update resumen_tarjeta extraction to handle Naranja card format

Context Gathering

IMPORTANT: Do NOT hardcode MCP names or folder paths. Always read CLAUDE.md to discover:

1. Available MCP servers - Look for the "MCP SERVERS" section to find:

   • Google Drive MCP for file access (gdrive_search, gdrive_read_file, gsheets_read, etc.)
   • Railway MCP for deployment context (get-logs, list-deployments, list-services, list-variables)
   • Gemini MCP for prompt testing (gemini_analyze_pdf)

2. Folder structure - Look for "FOLDER STRUCTURE" section to understand:

   • Where documents are stored
   • Naming conventions for folders

3. Project structure - Look for "STRUCTURE" section to understand:

   • Source code organization
   • Test file locations
   • Where to add new files

4. Spreadsheet schemas - Look for "SPREADSHEETS" section or read SPREADSHEET_FORMAT.md

Workflow

1. Read PLANS.md - Pre-flight check
2. Read CLAUDE.md - Understand TDD workflow, agents, project rules, available MCPs
3. Parse $ARGUMENTS - Understand what needs to be implemented
4. Explore codebase - Use Glob/Grep/Task to find relevant files and understand patterns
5. Gather MCP context - If the task relates to:
   • Document processing → Check Drive files, spreadsheet schemas
   • Deployment → Check service status, recent logs
   • Extraction issues → Check current prompts, test with Gemini MCP
6. Generate plan - Create TDD tasks with test-first approach
7. Write PLANS.md - Overwrite with new plan

Codebase Exploration Guidelines

When to explore:

• Always explore to find existing patterns before creating new code
• Find related tests to understand testing conventions
• Locate where similar functionality already exists

How to explore:

• Use Glob for finding files by pattern: src/**/*.ts, **/*.test.ts
• Use Grep for finding code: function names, type definitions, error messages
• Use Task with subagent_type=Explore for broader questions about the codebase

What to discover:

• Existing functions that could be reused or extended
• Test file conventions and patterns
• Type definitions to reuse
• Similar implementations to follow as templates

PLANS.md Structure

# Implementation Plan

**Created:** YYYY-MM-DD
**Source:** Inline request: [Summary of $ARGUMENTS]

## Context Gathered

### Codebase Analysis
- **Related files:** [files found through exploration]
- **Existing patterns:** [patterns to follow]
- **Test conventions:** [how tests are structured in this area]

### MCP Context (if applicable)
- **MCPs used:** [which MCPs were consulted]
- **Findings:** [relevant information discovered]

## Original Plan

### Task 1: [Name]
1. Write test in [file].test.ts for [function/scenario]
2. Run test-runner (expect fail)
3. Implement [function] in [file].ts
4. Run test-runner (expect pass)

### Task 2: [Name]
1. Write test...
2. Run test-runner...
3. Implement...
4. Run test-runner...

## Post-Implementation Checklist
1. Run `bug-hunter` agent - Review changes for bugs
2. Run `test-runner` agent - Verify all tests pass
3. Run `builder` agent - Verify zero warnings

Task Writing Guidelines

Each task must be:

• Self-contained - Full file paths, clear descriptions
• TDD-compliant - Test before implementation
• Specific - What to test, what to implement
• Ordered - Dependencies resolved by task order
• Context-aware - Reference patterns and files discovered during exploration

Good task example:

### Task 1: Add validateCuit function
1. Write test in src/utils/validation.test.ts for validateCuit
   - Test valid CUIT returns true (use existing test fixtures)
   - Test invalid checksum returns false
   - Test invalid format returns false
   - Follow existing validation function patterns
2. Run test-runner (expect fail)
3. Implement validateCuit in src/utils/validation.ts
   - Use modulo 11 algorithm
   - Follow existing function signature patterns
4. Run test-runner (expect pass)

Bad task example:

### Task 1: Add CUIT validation
1. Add function
2. Test it

MCP Usage Guidelines

Google Drive MCP - Use when task involves:

• Document processing or extraction
• Spreadsheet column changes
• File organization or naming
• Understanding current document formats

Railway MCP - Use when task involves:

• Deployment configuration
• Environment variables
• Service logs for debugging context

Gemini MCP - Use when task involves:

• Prompt improvements
• Extraction accuracy
• Test prompt variations before planning changes

Rules

• Refuse to proceed if PLANS.md has incomplete work
• Explore codebase before planning - Find patterns to follow
• Use MCPs when relevant - Gather context from external systems
• Every task must follow TDD (test first, then implement)
• No manual verification steps - use agents only
• Tasks must be implementable without additional context
• Always include post-implementation checklist
• Do NOT modify TODO.md (this skill bypasses backlog management)

CRITICAL: Scope Boundaries

This skill creates plans. It does NOT implement them.

1. NEVER ask to "exit plan mode" - This skill doesn't use Claude Code's plan mode feature
2. NEVER implement code - Your job ends when PLANS.md is written
3. NEVER ask ambiguous questions like "should I proceed?" or "ready to continue?"
4. NEVER start implementing after writing the plan, even if user says "yes" to something

Termination

When you finish writing PLANS.md, output this exact message and STOP:

✓ Plan created in PLANS.md

Next step: Run `plan-implement` to execute this plan.

Do not ask follow-up questions. Do not offer to implement. Just output the message and stop.
