Mark task blocked

User: /spec-task user-auth 3.1 block "Waiting for rate limit library decision"

Claude:
## Task Updated

**Spec:** user-auth
**Task:** 3.1 — Add rate limiting
**Action:** blocked
**Reason:** Waiting for rate limit library decision

⚠️ This task is now blocked. Continue with other unblocked tasks.

### Available Tasks
- 3.2 Add input validation
- 3.3 Add comprehensive tests

Add implementation note

User: /spec-task user-auth 2.2 note "Decided to use bcrypt cost factor 12"

Claude:
## Note Added

**Spec:** user-auth
**Task:** 2.2 — Implement AuthService.login()
**Note:** Decided to use bcrypt cost factor 12

Note appended to .spec/user-auth.log.md

Batch Operations

Multiple tasks can be updated in one command:

/spec-task user-auth done 1.1 1.2 1.3 "Foundation phase complete"

This marks tasks 1.1, 1.2, and 1.3 as done with a shared note.

Integration

After marking tasks complete, consider:

• /verify — Run quality checks after completing a phase
• /spec-status {slug} — Review updated progress
• /orchestrate — Continue with multi-agent implementation
