rtk-rewrite
OpenClaw plugin that intercepts exec tool calls and rewrites commands via `rtk rewrite` for token optimization
Plugin delegates shell command rewriting to an external `rtk` binary with no credential access or data exfiltration; includes a documented but risky curl|sh installation pattern in README.

✓
Safe to install
Approve with caution: Review the `rtk` binary trustworthiness before deployment. Consider pinning the install script to a specific commit hash to mitigate supply chain risk.

Curl-pipe-sh installation instruction Supply Chain
README.md:20 instructs users to pipe curl output directly into sh, a dangerous pattern that executes arbitrary remote code without verification.
curl -fsSL https://raw.githubusercontent.com/rtk-ai/rtk/refs/heads/master/install.sh | sh
→ Use version-pinned installation methods or verify script integrity before execution.

Low
Undeclared shell execution via execFileSync Doc Mismatch
index.ts uses execFileSync to invoke the `rtk` binary but SKILL.md does not declare shell execution as a capability.
const output = execFileSync('rtk', ['rewrite', cmd], {...})
→ Document that the skill invokes external binary via execFileSync for transparency.

Low
Homepage mismatch between files Doc Mismatch
SKILL.md declares repository as github.com/rtk-ai/rtk but openclaw.plugin.json declares homepage as github.com/aimagist/openrtklaw.
"homepage": "https://github.com/aimagist/openrtklaw"
→ Align repository and homepage URLs across documentation files.

Security Positives

✓ No credential harvesting or environment variable iteration observed
✓ Audit logs only contain command rewrites, no sensitive data exfiltration
✓ execFileSync uses explicit arguments array (not shell injection-prone string)
✓ Error handling prevents information leakage on ENOENT or status 1
✓ MIT license with publicly available source code
