Affected: Homebrew: openclaw-cli

### Summary In `openclaw` versions up to and including `2026.2.22-2`, a non-default exec-approval configuration could allow a skill-name collision to bypass an `ask=on-miss` prompt.

When `autoAllowSkills=true`, a path-scoped executable such as `./skill-bin` could resolve to basename `skill-bin`, satisfy the `skills` allowlist segment, and run without prompting for approval.

### Affected Packages / Versions - Package: `npm openclaw` - Affected versions: `<= 2026.2.22-2` - Patched versions: `>= 2026.2.23` (released)

### Configuration Scope (Not Default) This behavior requires non-default settings and does not affect default installs.

Required conditions: - `autoAllowSkills=true` (default is `false`) - `system.run` with `security=allowlist` - `ask=on-miss`

### Technical Details The allowlist evaluator accepted `skills` satisfaction by bin-name match, so `./skill-bin` could match `skillBins.has("skill-bin")` after resolution.

The fix hardens skill auto-allow matching by requiring: - a pathless invocation token (no `/` or `\\`), and - a trusted resolved executable path for that skill bin on the machine where skills run.

This preserves normal `skill-bin ...` behavior while preventing `./<skill-bin>` and absolute-path basename collisions from auto-satisfying `skills`.

### Impact In affected non-default configurations, approval prompts could be skipped for commands that should have required operator confirmation.
