+# Native connection prompt reduction
+
+## Scope
+
+Compare one fixed-prompt reduction against unchanged merged master
+`378e6d95e1fbd52298f56ffcd5e261f80965b6b8`, which includes #15471.
+Remove 40 words / 261 UTF-8 bytes from the fixed native prompt. The removed
+three sentences repeat how to follow search instructions, use existing access
+for ordinary work, and present the connection card. Existing connection-tool
+descriptions and returned instructions carry this guidance unchanged.
+
+Keep the fixed rules for searching first on explicit connection requests,
+finishing independent work before yielding, avoiding repeated requests/polling,
+automatic continuation, and respecting declines. Keep every tool description,
+schema, shared legacy instruction, per-connection instruction, permission,
+runtime implementation, fixture and grader unchanged. Bump the fixed prompt
+revision to v7 so existing sessions cannot silently retain the previous prompt.
+
+## Measurement
+
+Use the existing production authority and scripted start/resume/continuation
+capture on both exact source variants, including the authenticated OpenCode MCP
+catalog. Compare combined instructions, supplied tools and task input. Report
+UTF-8 bytes separately from unknown provider tokens, loading and billed costs.
+A byte reduction is not proof of model behavior or a billing improvement.
+
+## Matched live comparison
+
+Run the same fifteen explicit Product E2E cells once per variant:
+service-approve, service-decline, connection-decline, provider-decline and
+provider-second across native Codex `gpt-5.6-sol`, ACPX Claude
+`claude-sonnet-5` and OpenCode
+`openrouter/deepseek/deepseek-v4-flash-0731`. Use distinct target branches
+and the trusted default-branch workflow; retain its actual immutable revision.
+
+Keep the existing 1,000-cent company/agent hard stops, 720-second cell deadline,
+twelve-run ceiling, one original attempt per cell and no automatic retries.
+Use maximum parallelism three per campaign. All provider turns and any
+pre-execution failures remain in the accounting; missing charges mean unknown.
+
+The suite hash is
+`85a212a8b1b70149c0e51bf01fe5d1391d1d6fb16926b47c65c0e6b55044ec54`.
+The definition digest is
+`326160800748260fd8a1daad9e19dfec0342decfe969427e9f743df16201e7af`.
+Verify both from each source before dispatch. Retain original grades and compare
+exact case pairs and saved content: documents and returned markers, saved
+decisions, service-call counts, attributable explanations, continuation, final
+output and cleanup. Inspect a failure before proposing any further paid run;
+do not reroll a usable behavior failure into a pass.
+
+## Limits and disposition
+
+This is a candidate pending live qualification. The earlier 15/15 repair result
+was measured on 09a before the final #15471 review fixes; it is not the baseline
+for this reduction. This comparison uses one common merged context instead.
+
+The suite does not qualify successful new authentication/setup, agent grants,
+independent work while waiting, explicit reconsideration after decline, or
+general coding quality. It detects duplicate saved interactions, not every
+repeated idempotent tool call. A single pair per cell does not establish general
+equivalence, speed or cost trends. The failed hiring-only reduction #15389 stays
+held and is not part of this comparison.
