Implementation Reference

• src/cli/registry.ts:86-111 (handler)

  The core implementation of the 'reject' logic, which deactivates an instinct and adjusts its confidence.

  /** Reject an instinct: deactivate and drop confidence. */
  async reject(id: string): Promise<Instinct> {
    const entry = await this.find(id);
    if (!entry) throw new Error(`Instinct not found: ${id}`);
  
    const { file, instinctFile, instinct } = entry;
    instinct.active = false;
    instinct.confidence = Math.max(0, instinct.confidence - 0.3);
    // Ensure min_confidence doesn't exceed new confidence (Zod invariant)
    instinct.min_confidence = Math.min(instinct.min_confidence, instinct.confidence);
    instinct.updated_at = new Date().toISOString();
  
    // Record rejection in outcome_log
    const outcome: OutcomeEntry = {
      timestamp: new Date().toISOString(),
      result: 'negative',
      delta_confidence: -0.3,
      note: 'Rejected via CLI',
    };
    instinct.outcome_log.push(outcome);
  
    instinctFile.instincts[id] = instinct;
    await this.loader.save(file, instinctFile);
  
    return instinct;
  }

• src/server/index.ts:373-382 (handler)

  The MCP tool handler in the server that invokes the registry's reject method.

  case 'reject_instinct': {
    const id = String(args?.['id'] ?? '');
    if (!id) return { content: [{ type: 'text', text: 'Error: id is required' }] };
    try {
      const instinct = await registry.reject(id);
      return { content: [{ type: 'text', text: JSON.stringify({ rejected: id, confidence: instinct.confidence, active: instinct.active }, null, 2) }] };
    } catch (e) {
      return { content: [{ type: 'text', text: `Error: ${e instanceof Error ? e.message : String(e)}` }] };
    }
  }

• src/server/index.ts:179-188 (registration)
