| description | Isolated codebase exploration that preserves your main context. Use when you need to understand code structure, trace call paths, or gather evidence before making changes. Spawns an explorer subagent. |
Explore the codebase without polluting your main context.
"Spawn an explorer subagent to [describe the research goal]. Return a structured summary with: files examined, relevant symbols, call path trace, and key findings."
The explorer runs in read-only mode in isolated context — your main thread stays clean.
find . -name '*.ts' -path '*/auth/*' | head -20
grep -rn --color=never 'functionName' --include='*.ts' . | head -30
# 1. Find where the function is defined
grep -rn --color=never 'def functionName\|function functionName\|functionName =' . | head -10
# 2. Find all callers
grep -rn --color=never 'functionName(' . | grep -v 'def functionName\|function functionName' | head -20
Use file reading tools — do NOT cat the whole file.
After research, summarize findings:
## Research Summary: <topic>
### Files examined
- path/to/file.ts — reason
### Key symbols found
- SymbolName (file:line) — what it does
### Call path trace
Entry → ServiceA.method → ServiceB.method → DB query
### Key findings
1. Finding 1
2. Finding 2
### Open questions

context/tasks/research-notes.md (not in main context)Build the project and verify it compiles cleanly. Use after making changes to confirm nothing is broken before running tests. Reads the build command from context/build.md.
Auto-configure .github/copilot-instructions.md and context/ knowledge docs for a new project. Use when setting up Brain Bootstrap in a new repository. Discovers the codebase, fills in templates, and writes project-specific configuration.
Save session state before context gets full or before ending. Writes current task state, branch, and loaded docs to context/tasks/todo.md so the next session can resume cleanly.
Clean workspace — build artifacts, dependencies, caches, Docker volumes, or temp files. Accepts arguments like build, deps, all, cache, docker, tasks, reinstall.
Load all relevant context/ knowledge files for a domain area. Use at session start or when switching to a new topic. Accepts a domain keyword like api, database, auth, build, security.
Query the database — list schemas, tables, describe a table, or run SQL. Accepts arguments like schemas, tables, describe <table>, or raw SQL.
