fix: move mission context to top of system prompt + auto-inject initial prompt
Mission context was buried at the end of a 21K char system prompt and the agent ignored it. Two fixes: 1. Mission block now emits FIRST in build_runtime_prompt() so it's the most prominent instruction the agent sees 2. When an active mission exists and no user prompt is given, auto-inject an initial user message triggering the agent to read mission state files Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

# ACTIVE MISSION — HARD GATE (Read Before Anything Else)
|
||||
|
||||
An active orchestration mission exists in this project. This is a BLOCKING requirement.
|
||||
|
||||
**Mission:** $m_name
|
||||
**ID:** $m_id
|
||||
**Status:** $m_status
|
||||
**Milestones:** $m_completed / $m_count completed
|
||||
|
||||
## MANDATORY — Before ANY Response to the User
|
||||
|
||||
You MUST complete these steps before responding to any user message, including simple greetings:
|
||||
|
||||
1. Read \`~/.config/mosaic/guides/ORCHESTRATOR-PROTOCOL.md\` (mission lifecycle protocol)
|
||||
2. Read \`docs/MISSION-MANIFEST.md\` for full mission scope, milestones, and success criteria
|
||||
3. Read the latest scratchpad in \`docs/scratchpads/\` for session history, decisions, and corrections
|
||||
4. Read \`docs/TASKS.md\` for current task state (what is done, what is next)
|
||||
5. After reading all four, acknowledge the mission state to the user before proceeding
|
||||
|
||||
If the user gives a task, execute it within the mission context. If no task is given, present mission status and ask how to proceed.

## MANDATORY First Actions
|
||||
|
||||
1. Load \`~/.config/mosaic/guides/ORCHESTRATOR-PROTOCOL.md\` (mission lifecycle protocol)
|
||||
2. Read \`docs/MISSION-MANIFEST.md\` for full mission scope, milestones, and success criteria
|
||||
3. Read \`docs/scratchpads/${m_id}.md\` for session history, decisions, and corrections
|
||||
4. Read \`docs/TASKS.md\` for current task state (what is done, what is next)
|
||||
5. Do NOT begin any coding or planning until you have read all four documents above
|
||||
|
||||
You are resuming an existing mission. The state files are the source of truth.
