Summary

  • parseClaudeRequest preserved a stray role: "system" message inside the incoming Messages API messages[] array as-is into conversation history. Once translated to an OpenAI-shaped request for a fallback provider (LiteLLM/vLLM), that system message could land past index 0, which the backend's chat template rejects ("System message must be at the beginning."). Fixed by folding any inline system-role message into systemPrompt and excluding it from history — mirroring how parseOpenAIRequest already handles this case.
  • Yama PR review now uses the qwen3.8-27b model instead of general-fast.

Status: holding for the Yama check

The Yama PR Review check is expected to stay red on this PR for now: the qwen3.8-27b model exposes a separate infrastructure issue — Yama's schema-bound calls go through NeuroLink generate() (non-streaming POST), so the Cloudflare-tunneled LiteLLM gateway 524s any completion slower than ~100s. The fix (generate-over-SSE inside NeuroLink's OpenAI-compat provider, then a Yama dependency bump) is being implemented separately; this PR stays open until that chain lands and the Yama job can be re-run green.

Test plan

  • pnpm run check + check:tools-tests — clean
  • pnpm run lint on changed files — clean
  • Added a regression case to testClaudeFormatRuntime in test/continuous-test-suite.ts covering an inline system-role message
  • Manually verified via the built dist/proxy/claudeFormat.js that an inline system message now folds into systemPrompt and is absent from conversationMessages
  • pnpm run build + test:providers-mocked + test:provider-structure + test:model-manifests (pre-push gate) — all passing
  • All CI checks green except Yama (see Status above)

📝 Walkthrough

Walkthrough

The Claude request parser now folds inline system messages into systemPrompt and excludes them from conversation history. Tests cover this behavior. The repository now uses a vendored Yama v4 action with new review configuration, state handling, report publication, and verdict enforcement.

Changes

Claude request parsing

Layer / File(s) Summary
Inline system message handling
src/lib/proxy/claudeFormat.ts, test/continuous-test-suite.ts
Inline system messages populate systemPrompt from string or text-block content and are excluded from conversationMessages. Runtime coverage validates this behavior.

Yama v4 review integration

Layer / File(s) Summary
Yama v4 review configuration
.yama/yama.yaml, .yama/review.yaml, .yama/policy/guards.yaml, .yama/rules/claude-md.yaml, .yama/knowledge/*, .yama/mcp.yaml
Adds Yama v4 model, review, policy, rule, knowledge, and MCP configuration.
Vendored review action
.github/actions/yama-review/action.yml
Adds checkout validation, artifact state restoration, direct Yama CLI installation and invocation, review execution, and no-report failure handling.
Report and workflow wiring
.github/actions/yama-review/action.yml, .github/workflows/yama-review.yml, .gitignore
Publishes report-derived outputs, persists state, optionally fails on blocked verdicts, and updates the workflow for the vendored action, .yama/ configuration, and a 45-minute timeout.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 50582

The PR adds review automation that may analyze an incomplete diff or validate different settings than those used for review, while its reporting policy can copy detected credentials into repository comments and reports. The regression coverage also has bounded weaknesses around prompt preservation and failure output, so the PR is not merge-ready until these risks are fixed or explicitly accepted.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Remove recovered prompt content from the failure message.

Line 4486 logs parsedWithInlineSystem.systemPrompt. This value contains caller-controlled request content. Use a structural failure message instead. This prevents the harness from treating provider-like recovered content as an expected provider error.

Proposed fix
-        `Inline system message not folded into systemPrompt: ${parsedWithInlineSystem.systemPrompt}`,
+        "Inline system message was not folded into systemPrompt",

Based on learnings: “avoid interpolating recovered payload values into assertion messages.”

Assert that the existing system prompt is preserved.

The .includes("Inline system reminder") check passes if the parser discards "You are helpful" and keeps only the inline message. Assert the complete merged value, or assert both prompts and their order.

28-30: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Pass checks: false from the workflow so the disabled stage cannot be re-enabled by the action default.

.github/actions/yama-review/action.yml defaults the checks input to "true" and exports it as YAMA_CHECKS. The workflow does not override it. If the runtime gives the environment variable precedence over stages.checks, the checks stage runs despite this file disabling it. The repository configures no checks, so the effect is small today, but the two sources of truth disagree.

Fail when the pull request base cannot produce a merge base.

Line 127 detects a shallow checkout but only emits a warning. The action then passes --base "origin/${GITHUB_BASE_REF}" to Yama. If that ref or its merge base is unavailable, the review can fail or analyze an incomplete diff. Verify the base ref and merge base before the review starts.

-        if [ "$(git rev-parse --is-shallow-repository)" = "true" ]; then
-          echo "::warning::This is a shallow clone. Yama needs history to compute the diff against the base. Use fetch-depth: 0."

pre-review validation around the shallow-repository check to fail when the
configured base ref or its merge base is unavailable, rather than only warning.
Validate origin/${GITHUB_BASE_REF} and the merge base against HEAD before
invoking Yama, and exit with a clear error while preserving the existing review
flow when validation succeeds.

Pass the selected config input to doctor.

Export inputs.config as YAMA_INPUT_CONFIG and invoke doctor --config "$YAMA_INPUT_CONFIG" so preflight validates the same configuration as review.

In @.github/actions/yama-review/action.yml around lines 175 - 193, Update the
workflow environment and doctor preflight so the selected config is propagated
consistently: export inputs.config as YAMA_INPUT_CONFIG, then include --config
with that value in DOCTOR_ARGS before invoking the CLI. Keep the existing
dry-run/live argument behavior unchanged so doctor validates the same
configuration used by review.

An OpenAI-compatible fallback backend (LiteLLM/vLLM) rejects any request
with a system message not at index 0. parseClaudeRequest preserved a
client's stray inline `role: "system"` message into conversation history
instead of merging it like parseOpenAIRequest already does, so it could
land past index 0 after translation and get rejected.

Also migrate the Yama PR review to v4 on the qwen3.8-27b model: the
single-file v3 config becomes the .yama/ tree (model chains, modern
GitHub MCP capability map, verdict policy, guards, distilled CLAUDE.md
rules, retrieved-on-demand knowledge), and the workflow moves to the v4
action, which handles state artifacts, preflight doctor, and
fail-on-blocked itself. Checks, ownership and learning stay off.
