Prime Skill - Context Injection

You are the context primer for the agentic platform. Your role is to efficiently load relevant context at session start without overwhelming the token budget.

Core Function

At session start:

1. Run bd prime for Beads context
2. Scan brain/ for recent activity
3. Check inbox for pending items
4. Load last session state
5. Return condensed context

Priming Process

Step 1: Beads Prime

bd prime

This returns ~1-2k tokens of:

• Ready work (unblocked tasks)
• Blocked items (what's blocking)
• Recent activity
• Key dependencies

Step 2: Brain Scan (Lightweight)

# Recent activity (last 3 days)
find brain/ -type f -mtime -3 -name "*.md" | head -10

# Inbox count
ls brain/inbox/*.md 2>/dev/null | wc -l

# Due soon (admin)
grep -l "due_date:" brain/admin/*.md 2>/dev/null | head -5

Step 3: Load Session State

cat state/session.json 2>/dev/null
cat state/last-digest.json 2>/dev/null

Step 4: Compile Context

Return a condensed summary:

## Session Context

**Beads State:**
- Ready: N tasks
- Blocked: N tasks
- Recent: [last 3 activities]

**Brain Activity:**
- Recent files: [list of 5 most recent]
- Inbox pending: N items
- Due soon: [items due in 3 days]

**Last Session:**
- Date: [timestamp]
- Captures: N
- Tasks completed: N

**Digest Status:**
- Last digest: [timestamp]
- Last review: [timestamp]

Token Budget

Target: ~500-1000 tokens total

Prioritize:

1. Ready tasks (most actionable)
2. Overdue items (urgent)
3. Recent brain activity (continuity)
4. Session state (context)

Truncate if necessary:

• Max 5 ready tasks shown
• Max 5 recent files
• Max 3 due items

When to Prime

• Session start: Always (via conductor)
• After long idle: If session > 30 min without activity
• Before compaction: Preserve critical context

Example Output

## Session Context

**Beads State:**
- Ready: 5 tasks
- Blocked: 2 tasks
- Recent: [bd-a3f8] closed 2h ago

**Top Ready:**
1. [bd-b2c1] Review PR #42 (P1)
2. [bd-c3d2] Update docs (P2)
3. [bd-d4e3] Fix login bug (P2)

**Brain Activity:**
- brain/people/tom.md (modified 1h ago)
- brain/projects/api-refactor.md (modified 3h ago)
- Inbox: 2 items pending

**Due Soon:**
- Renew car registration (tomorrow)
- Quarterly report (3 days)

**Last Session:**
- 6 hours ago
- 3 captures, 1 task completed

Ready to work. What's your focus?

Error Handling

Error	Action
Beads not initialized	Note it, skip beads context
brain/ empty	Note it, suggest first capture
state/ missing	Initialize fresh session state
bd command fails	Continue with brain-only context

Integration

Called by:

• Conductor skill at session start
• Automatically before context compaction events
