kmg-brainstorm-recall

Skill: kmg-brainstorm-recall

Purpose: Ensure the knowledge graph is consulted before any recommendation is made. Fires before kmg-adr-guide on the same trigger surface.

Trigger Keywords:

• "should we"
• "I'm thinking of"
• "best way to"
• "which approach"
• "let's consider"
• "what do you recommend"
• "how should we"
• When superpowers:brainstorming is invoked via Skill tool

Precedence: This skill fires BEFORE kmg-adr-guide. If both trigger, run recall first, then allow adr-guide to proceed.

Enforcement note (ENH-015): "Fires before" is not just a prose claim — it is enforced by the pre-skill-rules-inject.sh HARD BLOCK added in Task 6b. The hook injects the Brainstorm Recall block into context before the skill executes, making the recall step mandatory regardless of which skills auto-trigger. See knowledge/enhancements/ENH-015/ENH-015-specification.md §"Existing Skill Conflicts Resolved" for the full precedence rationale. The skill trigger overlap with adr-guide is intentional — ENH-015 documents why separate skills are correct (different lifecycle phases) and why merging produces unreliable auto-invocation.

Behavior:

1. Extract the topic from the user's question or the brainstorming context (1–5 words).

2. Run recall before answering: Invoke the kmgraph:kmg-recall skill (via Skill tool) with the extracted topic as input.

3. Present prior art under a "Prior Art" heading before your recommendation:

   • Relevant ADRs found
   • Relevant lessons-learned found
   • Known failed approaches
   • If nothing found: state "No prior art found for [topic]"

4. Then proceed with the recommendation or brainstorming, informed by the recall results.

Do not skip recall if the topic seems simple — recall takes seconds and prevents proposing already-rejected solutions.

ADR/ENH number pre-allocation (I-E): Before dispatching background fast-agents, brainstorm-recall must pre-allocate ADR and ENH numbers by reading current highest numbers from knowledge/decisions/ and knowledge/enhancements/. Pass resolved numbers in agent payload to prevent concurrent agents from claiming the same number.

Integration:

• Works alongside superpowers:brainstorming — does not replace it
• Recall results feed into kmg-adr-guide if a decision crystallizes from the brainstorm

Background agent dispatch (non-blocking):

After presenting recall results and proceeding with the brainstorm:

4. If the brainstorm surfaces a new architectural decision: dispatch a background fast-agent to draft an ADR:

   Agent({subagent_type: "kmgraph:create-adr-agent", run_in_background: true, prompt: "Draft ADR for: [decision]"})
   

5. If the brainstorm surfaces a new enhancement or feature idea: dispatch a background fast-agent:

   Agent({subagent_type: "kmgraph:knowledge-extractor", run_in_background: true, prompt: "Capture ENH for: [idea]"})
   

6. When background agents complete, present a review-or-save prompt:

   "ADR/ENH draft complete. Files at knowledge/decisions/ADR-NNN.md / knowledge/enhancements/ENH-NNN/. Review before saving, or save now?"

   • "Save now" → files already written, user reviews outside session
   • "Review first" → surface content inline for approve/edit/skip per item

7. Any Opus feedback or unresolved action items → write to the Open Questions section of the relevant ADR/ENH (never directly to session summary).
