Seine Research (Backend 2)

Phased research pipeline using Claude Code's native Agent tool. Requires drill or siege depth. Read agents/seine-kb/REFERENCE.md for schemas, ADR rules, and depth behavior.

Pipeline

Phase A (Discovery)    hunter + scout        → Evidence map + adjacent signals
    ↓ Gate A           validator             → PASS / PASS_WITH_NOTES / FAIL
Phase B (Analysis)     skeptic + referee     → Claim challenges + conflict resolution
    ↓ Gate B           validator             → PASS / PASS_WITH_NOTES / FAIL
Phase C (Synthesis)    adversarial-reviewer  → Red-team analysis
                       confidence-quantifier → Calibrated confidence scores

Gate failure stops the pipeline immediately (ADR-S009). Partial results returned with stopped_at field.

Step 1 — Phase A: Discovery (parallel)

Spawn hunter and scout simultaneously in a single message:

Agent({ subagent_type: "seine-research-hunter", model: "<drill=sonnet|siege=opus>",
        prompt: "Query: <query>\nPrior results: <search_results_json>\nTask: Build evidence map and confidence table." })
Agent({ subagent_type: "seine-research-scout",  model: "<drill=sonnet|siege=opus>",
        prompt: "Query: <query>\nPrior results: <search_results_json>\nTask: Find adjacent signals, weak signals, and timing triggers." })

Both must output the Research Agent Schema (KB Section 3): 6 required blocks — scope, findings, counter_evidence, confidence_table, gaps, sources (ADR-S007).

Step 2 — Gate A

Spawn validator with Phase A combined outputs:

Agent({ subagent_type: "seine-research-validator", model: "sonnet",
        prompt: "Query: <query>\nPhase A outputs: <hunter_json + scout_json>\nTask: Schema check + confidence assessment. Return PASS, PASS_WITH_NOTES, or FAIL." })
