From b59c6740dab642858a8b80d418ee24b9fd5d1a56 Mon Sep 17 00:00:00 2001 From: Theo Browne Date: Sat, 24 Oct 2026 15:30:00 -0700 Subject: [PATCH 01/33] feat(server): add MCP tool-use eval runner Runs small fake threads against Claude Sonnet 5.5 to see how agents use T3 Code's MCP tools. A captured Claude Code request gives the real system prompt, reminders, and native tools. T3 instructions and tool schemas are built from the checked-out source, so two branches can be compared. Includes five commit-safe example cases, a grader for every expect key, ToolSearch emulation for deferred T3 tools, --dry-run, and --baseline.

Text checks are now case-sensitive, as the cases are written. Delegated child cases build their prompt with T3's own taskPrompt, using the new setup.delegateRole, so a rewrite of that text is measured. Drop the CLAUDE.md reminder by default, so T3's text must work for every user. Remove --t3-tools inline, --kind, plain-request templates, and the hand-registered schema path, and simplify the default mocks.

Cases now describe a small fake world (branch, commits, diff, files, PRs, web pages). Bash, Read, Write, Edit, and WebFetch answer from it: git, gh, and common read commands work on compound commands, pipes, heredocs, and redirects, without running anything on the host. Shell mocks still win per command part. T3 defaults echo their inputs (task ids, PR identity, linked PRs), a delegated child's watch gets T3's real error, and the gitStatus reminder comes from the world. Also: mocks apply to native tools, prior tool calls replay one per step, the system prompt is cached across samples, --case takes a list, max steps is 10, and results keep each sample's transcript.

A small model now plays the machine instead: for each shell, Read, Edit, Write, or WebFetch call that no shell mock answers, Haiku 5.5 at low effort gets the case's world, the sample's earlier calls and outputs, and the new call, and returns only the output in a JSON field. Nothing runs on the host. Shell mocks still win on simple commands, and a delegated child's watch_pull_request still gets T3's refusal. Runs are cheaper: a sample stops once a must-not check has failed, --max-steps defaults to 6 with per-case maxSteps, and each case gets 2 samples plus a 3rd only when they disagree (--samples N still fixes the count). The summary reports cost per sample and simulator cost. The commit-safe cases now live in scripts/mcp-tool-use-cases/*.jsonl without their source fields and load by default. --cases still loads private files. The example cases file is gone.

Cross-provider work, explicit settings, and work that outlives the turn still need delegate_task. A Claude Agent call with no run_in_background counts as background, which is Claude Code's default. The secret check no longer matches "paste the build log here", and "not on PATH" counts as an unavailable provider. Sol's code-mode cells take more model calls, so unset --max-steps now means 6 for Claude and 10 for Sol.

Expected calls may now list alternatives ("link_pull_request|watch_pull_request"). Delegated-child cases stay strict, because T3 refuses a watch from a child.

Three only make sense on a Claude parent (Opus is cross-provider from Codex; the shot skill and image output exist only on the Claude path). A new Codex guard checks that same-model subagents use spawn_agent (issue 23525). Sol gets 4 more steps on cases with their own budget. Checks now accept a curly apostrophe, any schedule shape for a one-off check, and one child-thread read after an async delegate.

Cases that only required a link_pull_request call after gh pr create now check that the PR is linked at the end (new `linked` check), by T3 or the agent. The shell-token secret case now expects request_secret with delivery "file", and request_secret has a default result for both deliveries.
