context-map
Skill166 starsChanged 5 months agoMITView on GitHub
Generate a context map of all files relevant to a task before implementing changes. Use when a user says "map the codebase for this change", "what files are affected", "show me dependencies", or before starting implementation to identify files to modify, dependencies, test files, and reference patterns.
We split this skill into the rules it gives an agent
5 rules. 1 is common, 4 are distinctive, and 0 are very specific to this project.
1
Common
Most of the 6 edited versions we read keep these.
4
Distinctive
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 17
Use this skill when:
- Distinctive: line 24
Before implementing any changes, analyze the codebase and create a context map.
- Distinctive: line 32
Search the codebase for files related to this task
- Distinctive: line 35
Look for similar patterns in existing code
- Common: line 68
Do not proceed with implementation until this map is reviewed.
“Common” is measured: kept by at least 6 in 10 of the 6 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Context Map
When to Use
Use this skill when:
- Preparing to implement changes and need to understand the affected codebase
- Identifying all files, dependencies, and tests related to a task
- Finding reference patterns and similar implementations in the codebase
- Creating a pre-implementation analysis to reduce missed changes
Before implementing any changes, analyze the codebase and create a context map.
Task
{{task_description}}
Instructions
- Search the codebase for files related to this task
- Identify direct dependencies (imports/exports)
- Find related tests
- 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 requiredDo not proceed with implementation until this map is reviewed.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
