lth:brief — Task Brief Generator

Transforms a one-line task description into a structured brief that agents can act on directly. Pulls prior art, constraints, and applicable patterns from lth memory.

Usage

/lth:brief "Add rate limiting to API"

Output

Writes .bob/state/brief.md with:

• Context — relevant memories from lth (principles, techniques, recent history)
• Prior Art — similar work done before (from L4/L5 memory)
• Constraints — rules and invariants that apply (from L1/L2)
• Suggested Approach — synthesized from above

Instructions

ARGUMENTS handling: use the provided argument as the task description.

1. Ensure daemon is running:

   export PATH="$HOME/bin:$PATH"
   ~/bin/lth stats
   

2. Generate context using lth prompt:

   CONTEXT=$(~/bin/lth prompt "[TASK_DESCRIPTION]" --top-each 6 2>/dev/null)
   

   If lth prompt is not yet available (pre-install), fall back to:

   PRINCIPLES=$(~/bin/lth search "[TASK_DESCRIPTION]" --layers L1,L2 --top 5)
   TECHNIQUES=$(~/bin/lth search "[TASK_DESCRIPTION]" --layers L3 --top 8)
   PRIOR_ART=$(~/bin/lth search "[TASK_DESCRIPTION]" --layers L4,L5 --top 5)
   

3. Create .bob/state/ directory if needed:

   mkdir -p .bob/state
   

4. Write .bob/state/brief.md with this structure:

   # Task Brief: [TASK_DESCRIPTION]
   
   Generated: [date]
   
   ## Context
   [paste lth prompt output or formatted principles/techniques]
   
   ## Prior Art
   [L4/L5 memories showing similar past work]
   
   ## Constraints
   [L1/L2 principles and rules that apply to this task]
   
   ## Suggested Approach
   [synthesize from above: 3-5 bullet points recommending how to tackle the task]
   

5. Print confirmation: ✓ Brief written to .bob/state/brief.md
