-> **`cargo install clawcode` will not work** — this package is not published on crates.io. Build from source as shown below.
+> [!WARNING]
+> **`cargo install claw-code` installs the wrong thing.** The `claw-code` crate on crates.io is a deprecated stub that places `claw-code-deprecated.exe` — not `claw`. Running it only prints `"claw-code has been renamed to agent-code"`. **Do not use `cargo install claw-code`.** Either build from source (this repo) or install the upstream binary:
+> ```bash
+> cargo install agent-code   # upstream binary — binary name is 'agent-code', not 'claw'
+> ```
+> This repo (`ultraworkers/claw-code`) is **build-from-source only** — follow the steps below.

 50. **PowerShell tool is registered as `danger-full-access` — workspace-aware reads still require escalation** — dogfooded 2026-04-10. User running `workspace-write` session mode (tanishq_devil in #claw-code) had to use `danger-full-access` even for simple in-workspace reads via PowerShell (e.g. `Get-Content`). Root cause traced by gaebal-gajae: `PowerShell` tool spec is registered with `required_permission: PermissionMode::DangerFullAccess` (same as the `bash` tool in `mvp_tool_specs`), not with per-command workspace-awareness. Bash shell and PowerShell execute arbitrary commands, so blanket promotion to `danger-full-access` is conservative — but it over-escalates read-only in-workspace operations. Fix shape: (a) add command-level heuristic analysis to the PowerShell executor (read-only commands like `Get-Content`, `Get-ChildItem`, `Test-Path` that target paths inside CWD → `WorkspaceWrite` required; everything else → `DangerFullAccess`); (b) mirror the same workspace-path check that the bash executor uses; (c) add tests covering the permission boundary for PowerShell read vs write vs network commands. Note: the `bash` tool in `mvp_tool_specs` is also `DangerFullAccess` and has the same gap — both should be fixed together.

 51. **Windows first-run onboarding missing: no explicit Rust + shell prerequisite branch** — dogfooded 2026-04-10 via #claw-code. User hit `bash: cargo: command not found`, `C:\...` vs `/c/...` path confusion in Git Bash, and misread `MINGW64` prompt as a broken MinGW install rather than normal Git Bash. Root cause: README/docs have no Windows-specific install path that says (1) install Rust first via rustup, (2) open Git Bash or WSL (not PowerShell or cmd), (3) use `/c/Users/...` style paths in bash, (4) then `cargo install claw-code`. Users can reach chat mode confusion before realizing claw was never installed. Fix shape: add a **Windows setup** section to README.md (or INSTALL.md) with explicit prerequisite steps, Git Bash vs WSL guidance, and a note that `MINGW64` in the prompt is expected and normal.

+52. **`cargo install claw-code` false-positive install: deprecated stub silently succeeds** — dogfooded 2026-04-10 via #claw-code. User runs `cargo install claw-code`, install succeeds, Cargo places `claw-code-deprecated.exe`, user runs `claw` and gets `command not found`. The deprecated binary only prints `"claw-code has been renamed to agent-code"`. The success signal is false-positive: install appears to work but leaves the user with no working `claw` binary. Fix shape: (a) README must warn explicitly against `cargo install claw-code` with the hyphen (current note only warns about `clawcode` without hyphen); (b) if the deprecated crate is in our control, update its binary to print a clearer redirect message including `cargo install agent-code`; (c) ensure the Windows setup doc path mentions `agent-code` explicitly.
