Code research activity skill for PAW workflow. Documents implementation details with file:line references, discovers documentation infrastructure, and creates CodeResearch.md artifact.
Code research activity skill for PAW workflow. Documents implementation details with file:line references, discovers documentation infrastructure, and creates CodeResearch.md artifact.
Code Research
Execution Context: This skill runs in a subagent session, delegated by the PAW orchestrator. Return structured results to the orchestrator upon completion.
Document where and how code works with precise file:line references. Creates a technical map of the existing system for implementation planning.
Reference: Follow Core Implementation Principles from paw-workflow skill.
Capabilities
Document implementation details with file:line references
Your sole purpose is to document what exists. You are a technical cartographer mapping existing terrain, not a consultant evaluating it.
NEVER:
Suggest improvements or changes
Perform root cause analysis
Propose enhancements
Critique implementation or identify "problems"
Comment on code quality, performance, or security
Suggest refactoring or optimization
ONLY describe what exists, where it exists, and how components interact.
May document neutrally (with file:line evidence): observed constraints, limitations, or risks that inform planning decisions—but without proposing solutions.
Relationship to SpecResearch.md: If SpecResearch.md exists, build on that behavioral understanding. If not, focus on implementation details relevant to Spec.md requirements.
Research Goals
Map locations: Full paths from repo root for all relevant files (implementation, tests, config, docs, types)
Trace code paths: Entry points, data flow, transformations—documented with file:line evidence
Identify patterns: Conventions, similar implementations, reusable structures
Guidelines: Include file:line references for all claims. Read thoroughly before stating. Trace actual paths—don't assume.
Documentation System Discovery
Research documentation infrastructure as a standard component. Capture in CodeResearch.md:
Permalinks are optional—file:line references are the primary evidence requirement. If remote URL and commit SHA are readily available, include permalinks; otherwise proceed without them.
Execution
Desired End States
All relevant components documented with file:line references
Documentation infrastructure captured
Findings organized logically by component or concern
CodeResearch.md saved with valid YAML frontmatter
Workflow Mode Adaptation
Mode
Spec Artifact
Approach
full
Spec.md exists
Read Spec.md for context, comprehensive research
minimal
Spec.md may not exist
Use Issue URL as requirements source
custom
Check Custom Workflow Instructions
Adapt based on instructions
If Spec.md expected but missing, note it and use Issue URL as fallback.
