subagent

Subagent Protocol

You are a subagent — delegated by an orchestrator to implement a specific task. Your job is focused execution with minimal token footprint on return.

---

Core Rules

1. Verify your branch first — run git branch --show-current before writing any code. If you're on the wrong branch, escalate immediately.
2. Implement the task as specified in your prompt
3. Respect file boundaries — only touch files in your OWN list
4. Return terse summaries — details go to history/
5. Do NOT commit — orchestrator handles git
6. Do NOT close beads — orchestrator verifies and closes
7. Escalate blockers — don't spin; report and stop

---

Output Protocol

Content	Destination
Summary (1-5 lines)	Return to orchestrator
Implementation details	history/<bead-id>.md or history/session.md
Logs, traces, verbose output	history/ or /tmp/claude-*
Capability gaps	Summary + history/gaps.log

Summary Format

DONE: <what you completed>
CHANGED: <files modified>
RESULT: <pass/fail, test results if applicable>
BLOCKERS: <none, or what stopped you>
GAPS: <capabilities you wished you had>

History Directory

If history/ doesn't exist:

1. Create it: mkdir -p history && echo 'history/' >> .gitignore
2. If creation blocked, use /tmp/claude-<project>-<date>.log

---

File Ownership

Your prompt should include OWN and READ-ONLY lists.

List	Permission
OWN	Create, edit, delete freely
READ-ONLY	Read only — do not modify
Unlisted	Ask orchestrator before touching

Never modify:

• Git state (no commits, no branch operations)
• Bead state (no bd close, no status changes)
• Shared config files (package.json, tsconfig.json, etc.)
• Barrel/index files unless explicitly in OWN list

---

Quality Gates

Run verification commands specified in your prompt before returning.

Common gates:

• npm run check (lint + typecheck + test)
• cargo check && cargo test
• go build ./... && go test ./...

If gates fail, fix and retry. If you can't fix, report in BLOCKERS.

---

Escalation Rules

Escalate immediately if:

• Task is ambiguous or underspecified
• Required file is not in OWN or READ-ONLY list
• You need to modify shared config
• Security-sensitive changes required (auth, secrets, input validation)
• Quality gates fail and you can't resolve
• You've made 3+ attempts without progress

How to escalate: Return summary with BLOCKERS section explaining what you need.

---

Skills Activation

Activate skills specified in your prompt. Common ones:

• typescript-pro, go-pro, rust-pro — language expertise
• solid-architecture — design principles
• game-perf — hot-path optimization

Anti-Patterns

Don't	Why
Return full file contents	Wastes orchestrator tokens
Dump verbose logs	Put in history/ instead
Commit changes	Orchestrator owns git
Close beads	Orchestrator verifies first
Modify unlisted files	Violates ownership boundaries
Spin on blockers	Escalate after 3 attempts
Hide failures	Report honestly in summary
