Two live users in #claw-code on 2026-04-08 hit adjacent auth confusion: varleg set OPENAI_API_KEY for OpenRouter but prefix routing didn't activate without openai/ model prefix, and stanley078852 put sk-ant-* in ANTHROPIC_AUTH_TOKEN (Bearer path) instead of ANTHROPIC_API_KEY (x-api-key path) and got 401 Invalid bearer token. Changes: 1. ApiError::MissingCredentials gained optional hint field (error.rs) 2. anthropic_missing_credentials_hint() sniffs OPENAI/XAI/DASHSCOPE env vars and suggests prefix routing when present (providers/mod.rs) 3. All 4 Anthropic auth paths wire the hint helper (anthropic.rs) 4. 401 + sk-ant-* in bearer token detected and hint appended 5. 'Which env var goes where' section added to USAGE.md Tests: unit tests for all three improvements (no HTTP calls needed). Workspace: all tests green, fmt clean, clippy warnings-only.

Claw Code is the public Rust implementation of the claw CLI agent harness.
The canonical implementation lives in rust/, and the current source of truth for this repository is ultraworkers/claw-code.
Important
Start with
USAGE.mdfor build, auth, CLI, session, and parity-harness workflows. Makeclaw doctoryour first health check after building, userust/README.mdfor crate-level details, readPARITY.mdfor the current Rust-port checkpoint, and seedocs/container.mdfor the container-first workflow.
Current repository shape
rust/— canonical Rust workspace and theclawCLI binaryUSAGE.md— task-oriented usage guide for the current product surfacePARITY.md— Rust-port parity status and migration notesROADMAP.md— active roadmap and cleanup backlogPHILOSOPHY.md— project intent and system-design framingsrc/+tests/— companion Python/reference workspace and audit helpers; not the primary runtime surface
Quick start
cd rust
cargo build --workspace
./target/debug/claw --help
./target/debug/claw prompt "summarize this repository"
Authenticate with either an API key or the built-in OAuth flow:
export ANTHROPIC_API_KEY="sk-ant-..."
# or
cd rust
./target/debug/claw login
Run the workspace test suite:
cd rust
cargo test --workspace

Ecosystem
Claw Code is built in the open alongside the broader UltraWorkers toolchain:
