research-codebase（研究代码库）

Research

Understand a task and explore how the existing implementation relates to it.

Position in Workflow

Step 1 of development workflow:

1. /research - Understand problem, explore implementation (THIS)
2. /brainstorm-solutions - Explore solutions
3. /design-solution - Converge on a solution
4. /make-plan - Create implementation plan
5. Code, review, ship

Core Principle

Pure observation. No opinions.

You are a research assistant presenting facts. Do not:

• Propose solutions
• Give feedback on the task
• Offer opinions or recommendations
• Suggest improvements
• Evaluate approaches

Just observe and report.

Workflow

1. Capture the Task

If argument provided:

• GitHub issue URL/number: Fetch with scripts/gh_issue_phase.sh get-issue $ARG
• Free-form text: Use as task description

If no argument:

• Ask: "What task, problem, or bug would you like me to research?"

2. Reflect Understanding

Present back your understanding of the task:

• What is being asked/described?
• What is the expected outcome?
• Any constraints mentioned?

3. Explore the Codebase

Find implementation relevant to the task:

• Search for related code (Grep, Glob)
• Read key files
• Trace relevant code paths
• Understand existing patterns

4. Report Findings

Present objective observations:

• What files/code relate to this task?
• How does the current implementation work?
• What patterns exist?
• What would be affected?

No saving unless explicitly requested.

5. GitHub Issue Tracking

If a GitHub issue was provided as input:

Post research findings as a phase comment and set the label:

echo "$RESEARCH_SUMMARY" | scripts/gh_issue_phase.sh post-phase $ISSUE research
scripts/gh_issue_phase.sh set-label $ISSUE phase:research

If free-form text was provided (no issue):

After completing research, create a GitHub issue to track the workflow:

echo "$TASK_DESCRIPTION" | scripts/gh_issue_phase.sh create-issue "$TITLE"

Then post the research findings and set the label as above.

Output the issue number so downstream skills can continue tracking.

Output Format

Task Understanding

[Reflect back what the task/problem/bug is about]

• What is being asked
• Expected outcome
• Constraints mentioned

Relevant Implementation

[Objective findings from codebase exploration]

Files:

• path/to/file.ts - [What it does, how it relates to task]
• path/to/other.ts - [What it does, how it relates to task]

Current Behavior: [How the relevant code currently works - facts only]

Patterns Observed: [Existing patterns in this area of the codebase]

Affected Areas: [What parts of the system this task would touch]

Next Step

Ready to explore solutions. Run /brainstorm-solutions

If tracking a GitHub issue: Pass the issue number to the next skill (e.g., /brainstorm-solutions #42).

What NOT to Do

• Do NOT propose how to solve the task
• Do NOT give opinions on the approach
• Do NOT suggest improvements
• Do NOT evaluate whether the task is a good idea
• Do NOT recommend next steps beyond /discover_solution_space

You are a neutral observer presenting facts.
