Generate a map of all files relevant to a task before making changes

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

The context-map skill provides a systematic approach to pre-development planning. By requiring a comprehensive analysis of the codebase, dependencies, and testing requirements, it helps developers visualize the scope of a task and identify potential risks before writing code. The skill enforces a standardized output format that captures modified files, dependency impacts, relevant tests, and reference patterns, ensuring that changes are well-planned and documented.

What it does

  • Analyzes the codebase to identify files relevant to a specific task.
  • Maps direct dependencies and imports that may require updates.
  • Locates associated test files to ensure functional coverage.
  • Identifies existing code patterns to serve as implementation references.
  • Performs a structured risk assessment for breaking changes or infrastructure needs.

When to use it

  • Before starting a new feature implementation or bug fix.
  • When working in a complex codebase with many interdependencies.
  • When you need to ensure all affected areas are covered by tests.
  • When you want to minimize the risk of breaking existing functionality.

Advantages

  • Reduces the likelihood of missing side effects in dependent code.
  • Standardizes the planning phase of development tasks.
  • Provides a clear checklist of requirements before implementation begins.
  • Helps in identifying necessary database or configuration changes early.

Usage examples

“Create a context map for adding a new user authentication endpoint.”
The agent will scan the codebase for existing authentication logic, identify dependent API files, list relevant test suites, and provide a risk assessment table.
“I need to refactor the payment processing module. Generate a context map.”
The agent will produce a table of files to modify, identify downstream services that import the payment module, and highlight potential breaking changes.

Install

Documentation by vfaraji89

Context Map

Before implementing any changes, analyze the codebase and create a context map.

Task

{{task_description}}

Instructions

  1. Search the codebase for files related to this task

  2. Identify direct dependencies (imports/exports)

  3. Find related tests

  4. Look for similar patterns in existing code

Output Format

## Context Map

### Files to Modify
| File | Purpose | Changes Needed |
|------|---------|----------------|
| path/to/file | description | what changes |

### Dependencies (may need updates)
| File | Relationship |
|------|--------------|
| path/to/dep | imports X from modified file |

### Test Files
| Test | Coverage |
|------|----------|
| path/to/test | tests affected functionality |

### Reference Patterns
| File | Pattern |
|------|---------|
| path/to/similar | example to follow |

### Risk Assessment
- [ ] Breaking changes to public API
- [ ] Database migrations needed
- [ ] Configuration changes required

Do not proceed with implementation until this map is reviewed.
