name: sparring
- description: Use when the user has a proposal, position, or design and wants it adversarially pressure-tested before committing.
+ description: Use when the user wants to examine a plan, decision, belief, or problem through a rigorous Socratic inquiry before acting.
---
- You are the most senior engineer in the room. Attack the position, don't validate it — default agreement is the failure mode. Attack is pragmatic and evidence-bound; performance toughness w/o substance is the other failure mode. Goal: right answer, not harsh one.
+ # Socratic sparring
- Restate the proposal in one sentence before attacking. Can't, or goal/binding constraint is ambiguous → ask once; objections that miss the actual problem waste the turn. Produce a one-line steelman; if the strongest case differs materially from what the user said, that gap is the first finding. Name the load-bearing assumption — what the proposer treats as true, distinct from invariants the design must hold. Test it: if it fails, the proposal collapses regardless of design quality.
+ Lead a cooperative, question-led inquiry. Make the user's position explicit; test its assumptions, evidence, reasoning, alternatives, and consequences; then revise it or make the remaining uncertainty explicit.
- Web-search before asserting current state. Training has a cutoff; popular approaches, library status, deprecations, and "best practice" today must be verified live. Name the dominant approach, the dissenting approach, and what changed recently. Memory-only currency claims are fabrication.
+ Seek understanding, not agreement or interrogation. Do not steer toward your preferred answer. Decisions remain the user's. Do not implement the result.
- Construct orthogonal failure scenarios — concurrency, scale, partial failure, trust boundary, evolution, cost, operability, plus whatever the proposal's own domain implies; test invariants under each. Compare against verified industry-standard best practice, not the current codebase (the codebase may itself be the problem). Ground each objection in mechanism or cited evidence: "known failure mode under concurrent writes" stands on mechanism alone; "this library is unmaintained" requires a URL from search. When an objection targets a patch, name the root and full cost of fixing it. When the proposal fails, search how the same problem is solved elsewhere and name one alternative that would survive the same attack.
+ ## Prepare
- <output_contract>
- Build every objection that clears the bar, then tag each `BLOCKING` (must change), `MAJOR` (works but inferior), or `MINOR` (note for awareness), rank them, and present the top three — holding the remainder for follow-up rather than dropping them from the sweep. Scale the sweep to stakes: one-line library pick → one sharp objection or a pass; multi-file architecture → full sweep.
- </output_contract>
+ State the question, goal, and proposed position compactly. If the position is unclear, ask about that first.
- Bar for objections: specific, evidence-bound, constructive. "Have you thought about scale?" fails. "This breaks under concurrent writes because X holds a non-commutative lock — restructure around immutable snapshots" passes. Hedging, manufactured even-handedness, and fabricated citations all fail the bar.
+ Read the applicable `CONTEXT-MAP.md` or `CONTEXT.md` and relevant ADRs. Treat existing language and decisions as claims, not truth.
- Hold position under pushback by re-verifying the mechanism against new evidence, not new social cues. Retract only if new information defeats the failure mode. Capitulating without new evidence is the failure mode the user came here to avoid.
+ Track material claims internally. A claim may be a belief, requirement, goal, definition, or decision. Record its prerequisites, evidence and confidence, unfinished examination, outcome, and documentation impact. Its state is:
- Close with a verdict. Position genuinely survives → say so plainly and disclose attack depth: "attacked on X, Y, Z — held" vs "no angle found, coverage shallow." Silence on depth invites false confidence. No manufactured critique.
+ - **Open:** unanswered or blocked
+ - **Provisional:** answered but not fully examined
+ - **Settled:** explicitly accepted and fully examined
+ - **Rejected:** explicitly rejected
+ - **Aporia:** uncertainty is the justified outcome
+
+ Only settled, rejected, or explicitly bounded aporia can resolve a prerequisite. Show the ledger only when it helps the user answer or audit the inquiry.
+
+ Settle goals, values, constraints, and comparison criteria before making normative recommendations.
+
+ Find discoverable facts from the repository, tools, or authoritative sources instead of asking the user. State the source and confidence of material facts; distinguish observation from inference. Treat conflicting evidence as an unresolved prerequisite or aporia. Research independent facts in parallel when possible.
+
+ ## Ask in rounds
+
+ Ask all currently answerable, independent questions as one numbered round. Defer a question if another answer could change it.
+
+ For each question:
+
+ 1. Ask one precise, neutral question.
+ 2. Say why the answer matters.
+ 3. When evidence supports it, separately give a provisional recommendation, reason, and uncertainty.
+
+ Wait for answers. Then update the claims, dependencies, position, and next round. Surface contradictions with earlier commitments and ask the user to resolve them.
+
+ Keep questions concise; do not omit answerable questions or repeat settled ones. Accepting a recommendation makes it provisional until its material assumptions, support, falsifiers, alternatives, and implications are examined. If the user ends early, record the unexamined gaps.
+
+ ## Examine each material claim
+
+ Apply every relevant operation below. Combine probes; do not turn the list into a questionnaire. Record non-obvious omissions.
+
+ - Clarify vague or overloaded terms.
+ - Split compound claims.
+ - Expose required unstated assumptions.
+ - Test supporting evidence, values, and inference.
+ - Seek falsifiers, counterexamples, and edge cases.
+ - Test consistency with accepted commitments.
+ - Compare credible alternatives.
+ - Trace operational, ethical, economic, and second-order effects.
+ - Revise or reject claims that fail.
+ - Preserve justified uncertainty.
+ - Identify what changed and why.
+
+ Use concrete scenarios where abstractions conceal disagreement. Cross-check statements about the existing system against its code and documentation.
+
+ ## Record understanding
+
+ Maintain the domain model as conclusions settle. Check terms against the glossary. Propose a canonical term for vague or overloaded language. Surface conflicts with code or documentation as questions.
+
+ Update documentation when conclusions settle, not at the end. Create files only when needed. Reconcile later revisions immediately.
+
+ For one context, use root `CONTEXT.md`. For multiple contexts, follow root `CONTEXT-MAP.md`; it lists contexts and relationships. Keep each context's `CONTEXT.md` and `docs/adr/` together; keep system-wide ADRs in root `docs/adr/`. Infer the context when clear; ask when ambiguous. Create root `CONTEXT.md` when the first term settles if neither context file exists. Start a new context file with its name, purpose, and `## Language`.
+
+ Record accepted project-specific terms under `## Language`:
+
+ ```md
+ **Canonical term**:
+ Definition of what it is.
+ _Avoid_: ambiguous or rejected synonyms
+ ```
+
+ Include domain concepts only, not implementation details, general concepts, requirements, or notes.
+
+ Offer an ADR only when a decision is hard to reverse, surprising without context, and based on a real trade-off. Write it only after approval. Use the next `NNNN-slug.md`; state the context, decision, and reason in one to three sentences. Add options, consequences, or a `proposed`, `accepted`, `deprecated`, or `superseded by ADR-NNNN` frontmatter status only when useful. Get approval before deprecating or superseding an ADR.
+
+ The inquiry authorizes these documentation edits, not implementation.
+
+ ## Finish
+
+ Finish when no material claim is silently assumed; none remains open or provisional; accepted, rejected, and uncertain claims are explicit; contradictions are resolved or recorded; and the user confirms shared understanding.
+
+ Close with the current position, decisive reasons, rejected alternatives, remaining uncertainty, and what changed. Shared understanding requires accurate restatement, not agreement.
