Server instructions

Whetstone's public verifier toolbox as MCP tools. Three tiers. Tier 0 is stateless: you supply the data (exam rows, paired results, documents, event logs) and get back audits, promotion verdicts, patches, or counterexamples; payloads and results are not persisted, while operational counters and standard access logs are retained. Tier 1 is the disposable report card: report_card_start hands your agent a small graph-repair exam minted from the repository's public frontier, report_card_submit grades it by checker spec and requires a verified repair to retain at least 5% of clean support for promotion grade (no answer key exists), then destroys the session. Tier 2 is Open Promotion Bench: open_bench_start gives a paired baseline/candidate scope-integrity cohort, open_bench_submit grades both answer maps, and open_bench_leaderboard returns opt-in public receipts. Published entries retain only the self-attested manifests and sanitized receipts, never tasks or answers. No private exam bank is loaded in this service, so no tool can leak one. Complete request/response examples for every Tier 0 tool: GET /api/examples.

Known tools 14

inspect_promotion

Quarantine declared exposure, compare paired baseline/candidate outcomes on the clean remainder, and issue a promotion receipt.

Inferred read-only

audit_leakage

Exact declared-exposure audit over your exam rows: row identity, behavioral fingerprints for graph-DSL expressions, text-similarity review flags, and a clean exam export.

Inferred read-only

promotion_gate

PASS, HOLD, or BLOCK from paired per-item results: gains, regressions, exact McNemar p-value, per-domain breakdown.

Inferred read-only

bank_health

Item-lifecycle diagnostics over your grading history: discriminators, saturated and flaky items, frontier gaps.

Inferred read-only

safe_patch

Apply a section-scoped Markdown patch under conservation checks (untouched sections stay byte-identical; protected tokens preserved).

Inferred read-only

counterexample_hunt

Bounded simulated-annealing search for a graph counterexample inside a DSL predicate class, with an exact certificate when found.

Inferred read-only

memory_relevance

Compare query-free salience against objective-conditioned relevance for a set of memories under a token budget.

Inferred read-only

replay_trace

Turn reasoning-emulator control events into checkpoints, rewinds, notes, and a timeline.

Inferred read-only

report_card_start

TIER 1: start a disposable report-card session.

Inferred read-only

report_card_submit

TIER 1: submit answers for a report-card session and receive the graded report (per-item verdicts, per-domain totals, SHA-256 commitments).

Inferred read-only

open_bench_start

TIER 2: start a one-shot Open Promotion Bench session.

Inferred read-only

open_bench_submit

TIER 2: grade paired baseline and candidate patches, count gains/regressions/ties, and issue PASS/HOLD/BLOCK.

Inferred read-only

open_bench_leaderboard

TIER 2: list the self-attested public Open Promotion Bench receipts.

Inferred read-only
