Survey Patterns
Search the codebase for analogous features and reusable building blocks before planning a change, and read any source the task names outside this repo. Returns structured findings. Does not write code or plans.
Step 1: Identify the Task
Determine what the change is about:
- If a task description was passed in, use it
- Otherwise, derive it from conversation context (the user's latest request)
State the task back in one sentence to confirm scope before searching.
Step 2: Spawn Pattern Survey Sub-agent
Spawn a single sub-agent (inherited model defaults). Its prompt must direct it to treat the shared working tree and its git index as read-only and to survey by reading and reasoning. HEAD stays where it is: read other refs with git show <ref>:<path> rather than git checkout or git switch. The sub-agent's prompt must include:
- The confirmed task description from Step 1
- An instruction to read references/pattern-surveyor.md for survey guidelines, categories, and output format before searching
The sub-agent covers all three categories (Analogous Features, Reusable Utilities, Convention Anchors) in one sweep, reads any external source the task names, and returns a single structured report.
Step 3: Output Findings
Output the sub-agent's report verbatim. Do not reformat or re-synthesize — references/pattern-surveyor.md specifies the exact output format the sub-agent produces.
Then call update_plan to mark this step completed and continue with the next step of the active workflow.
Rules
- Do not write files.
- Do not propose implementation steps.
