The Anthropic Messages API requires every `tool_use` of an assistant message to be answered by `tool_result` blocks in the single message that follows it, so the second and later results of a parallel tool-call turn landed one message too late and the provider rejected the whole request: api returned 400 Bad Request (invalid_request_error): messages.3: `tool_use` ids were found without `tool_result` blocks immediately after: call_01_4QJqcZ0075kla1ILwra75582 Single-call turns were unaffected, which is why the defect only surfaced when the model requested several tools at once. Evidence: `.claw/sessions/ e49619b247aa3fce/session-1792170907799-0.jsonl`, whose step-1 assistant message carries two `tool_use` blocks followed by two separate tool-result messages. Fix: `convert_messages` is split into a per-message `convert_message` plus a folding accumulator `absorb_tool_result_message`, which merges a run of adjacent tool-result messages into the one `user` message that follows the assistant turn. The merge only extends a message whose content is tool results and nothing else, so user text and assistant turns can never be joined. `converts_tool_roundtrip_messages` keeps its previous single-call contract. Verification: `cargo test -p rusty-claude-cli` (224 unit tests plus the integration targets); `scripts/fmt.sh --check`.

A maximal 512-byte key expands to 1024 hex characters, so the generated path ran past the 1024-byte total-path limit enforced by APFS and `set`/`get` failed with ENAMETOOLONG: read terminal scope '…/6b6b…(1024 hex chars)….json': File name too long (os error 63) The misleading part is where the limit lives: every component stayed within the 255-byte filename limit (five 180-byte directories plus a 129-byte leaf), so the errno named a generated leaf name the caller never chose, and shrinking the chunk cannot help because the hex expansion stays 1024 characters however it is split. The same code passes on Linux, where `PATH_MAX` is 4096, so the `cargo test --workspace` job on ubuntu-latest could not catch it. Fix: records are named from a fixed-width SHA-256 digest (`<32 hex>.json`) and the multi-level chunking is gone. The full key still lives in `TerminalScopeRecord::correlation_key` and is still checked on read, so `encoded_keys_are_isolated_and_cannot_traverse_paths` keeps holding. `sha2` joins the crate's dependencies, reusing the version `runtime` already pulls, so `Cargo.lock` gains one line. The regression test now asserts on the path shape (longest component ≤ 255 bytes, total path < 1024 bytes) instead of only round-tripping, because a round trip inside a short temporary root succeeds even when the generated path is unusable in practice. Verification: `cargo test -p sdk` (119 unit tests, 12 + 109 integration); `scripts/fmt.sh --check`; the new assertion fails against the pre-fix code.

Cause: `mcp_stdio.rs` halves the production handshake budgets for test builds only — `MCP_INITIALIZE_TIMEOUT_MS` 200ms vs 10_000ms, `MCP_LIST_TOOLS_TIMEOUT_MS` 300ms vs 30_000ms — while the tests drive a real `python3` stdio fixture whose cold start measures 18-21ms (`min=18 max=21 avg=20` over 10 runs).

The `#[cfg(test)]` gate is why the impact is bounded: integration targets such as `runtime/tests/*.rs` link the non-test library and therefore use the production budgets, which is why only the two in-crate unit-test modules go red — no production path is affected, and no CLI or harness behavior depends on these values. [SCOPE: claw-code] + + **Disposition.** The budget constants were deliberately left unchanged: shortening them is what makes a real handshake regression fail fast, so widening them to buy parallel tolerance trades away the guard those cases exist for. Instead the cause is documented where the numbers are read, and this item records it for claws that hit the failures and misread them as a product defect. This mirrors the existing documented-but-unfixed items in this roadmap (for example the `clippy` job running without `-D warnings`). + + **How to read it.** Re-run with `--test-threads=1` before treating those failures as a regression. On the same machine and commit: `cargo test --workspace` (parallel) = 11 failed / 1792 passed; `cargo test --workspace -- --test-threads=1` = **0 failed / 1803 passed / 1 ignored**; `cargo test -p runtime --lib -- --test-threads=1` = 721 passed; `cargo test -p runtime --lib mcp_stdio:: -- --test-threads=1` = 22 passed. The failure set also moves between runs (`mcp_tool_bridge::tests::call_tool_payload_structure` and `manager_times_out_slow_tool_calls` each fail in one run and pass in the next), and libtest aborts in-flight cases when one panics, so the reported `passed` count itself varies between parallel runs — another sign that these are scheduling artifacts rather than deterministic defects. The single `ignored` case is `api/tests/client_integration.rs::live_stream_smoke_test`, which is marked `requires ANTHROPIC_API_KEY and network access`.

Third-party Anthropic-compatible endpoints accept the `ANTHROPIC_API_KEY` / `ANTHROPIC_AUTH_TOKEN` names purely as a wire-compatibility convention — the value has to be a credential the endpoint itself issued, and an `sk-ant-` key is rejected — so the message reads as "obtain an Anthropic key" while never mentioning the endpoint the user had already configured. `anthropic_missing_credentials_hint()` sniffed only `FOREIGN_PROVIDER_ENV_VARS` and ignored `ANTHROPIC_BASE_URL`, so users who had already pointed claw at a gateway got the generic wall. Fix: a `custom_anthropic_base_url_hint()` branch fires whenever `ANTHROPIC_BASE_URL` differs from `anthropic::DEFAULT_BASE_URL` (empty and whitespace-only values are ignored), names the configured URL, and explains the variable-name convention. It runs before the foreign-provider loop: a configured endpoint is a fact about what the user asked for, while a presence check on another provider's key only guesses at intent. Base-url resolution reuses `anthropic::read_base_url()` so the hint cannot disagree with the client's own endpoint. Seven pre-existing hint/error tests depended on the ambient `ANTHROPIC_BASE_URL` and failed under a shell that sets it; they now pin the variable explicitly. Verification: `cargo test -p api` (172 unit tests plus four integration targets); `scripts/fmt.sh --check`; the exact failing command now reports the endpoint it was configured with.

Instead the cause is documented where the numbers are read, and this item records it for claws that hit the failures and misread them as a product defect. This mirrors the existing documented-but-unfixed items in this roadmap (for example the `clippy` job running without `-D warnings`). **How to read it.** Re-run with `--test-threads=1` before treating those failures as a regression. On the same machine and commit: `cargo test --workspace` (parallel) = 11 failed / 1792 passed; `cargo test --workspace -- --test-threads=1` = **0 failed / 1803 passed / 1 ignored**; `cargo test -p runtime --lib -- --test-threads=1` = 721 passed; `cargo test -p runtime --lib mcp_stdio:: -- --test-threads=1` = 22 passed. The failure set also moves between runs (`mcp_tool_bridge::tests::call_tool_payload_structure` and `manager_times_out_slow_tool_calls` each fail in one run and pass in the next), and libtest aborts in-flight cases when one panics, so the reported `passed` count itself varies between parallel runs — another sign that these are scheduling artifacts rather than deterministic defects. The single `ignored` case is `api/tests/client_integration.rs::live_stream_smoke_test`, which is marked `requires ANTHROPIC_API_KEY and network access`. + +838. **DONE — Missing-credential message ignored a configured non-Anthropic `ANTHROPIC_BASE_URL`** — dogfooded while running `./target/debug/claw prompt "say hello"` with `ANTHROPIC_BASE_URL=https://api.deepseek.com/anthropic` and no credential exported. The error was truthful but misleading: `missing Anthropic credentials; export ANTHROPIC_AUTH_TOKEN or ANTHROPIC_API_KEY before calling the Anthropic API` names two env vars that a DeepSeek user does need to set, yet reads as "go obtain an Anthropic key" and never mentions the endpoint the user had already configured. Third-party Anthropic-compatible endpoints (DeepSeek's `/anthropic` path, corporate gateways, local proxies) accept those two variable names only as a wire-compatibility convention: the value must be a credential the endpoint itself issued, and an `sk-ant-` key will be rejected. `anthropic_missing_credentials_hint()` only sniffed `FOREIGN_PROVIDER_ENV_VARS` (`OPENAI_API_KEY` / `XAI_API_KEY` / `DASHSCOPE_API_KEY`) and never looked at `ANTHROPIC_BASE_URL`, so this whole class of user — someone who already knows what to configure — fell through to the generic wall. Fix: (1) a new `custom_anthropic_base_url_hint()` branch returns a hint whenever `ANTHROPIC_BASE_URL` is set to anything other than `anthropic::DEFAULT_BASE_URL` (empty or whitespace-only values are ignored); (2) the hint names the configured URL, states it is not the Anthropic API, and explains the variable-name convention; (3) the branch runs before the foreign-provider loop, because a configured endpoint is a fact about what the user asked for while a presence check on another provider's key only guesses at intent; (4) base-url resolution reuses `anthropic::read_base_url()` so the hint can never disagree with the client's own endpoint. [SCOPE: claw-code] + + **Verification.** Reproduced the exact command with the fix: the error now carries a third line naming `https://api.deepseek.com/anthropic`. New tests `anthropic_missing_credentials_hint_names_a_custom_base_url` (asserts the URL, the "not the Anthropic API" claim, and that both credential variable names survive), `anthropic_missing_credentials_hint_prefers_custom_base_url_over_foreign_creds` (pins the precedence rule against a regression, since both hints can apply at once), and `anthropic_missing_credentials_hint_is_none_for_the_default_base_url`. Seven pre-existing hint/error tests previously depended on the ambient `ANTHROPIC_BASE_URL` and now pin it explicitly, so they no longer pass or fail according to the developer's shell. `cargo test -p api` (172 unit tests plus the four integration targets); `scripts/fmt.sh --check`.
