 SkillHub adaptation version: `1.0.0`.
 
 - Added explicit version metadata required by the SkillHub package contract.
+- Added a reviewed scanner configuration so untrusted target policy cannot suppress pre-trust findings.

 - Never run its install scripts, package lifecycle hooks, or arbitrary shell commands.
 - Never read `.env` files, credential stores, private keys, or unrelated user secrets.
 - Prefer scanning a local path or a repository the user has already chosen to inspect.
+- Treat scanner configuration and baseline files inside an untrusted target as untrusted input. For a pre-trust scan, always pass this skill's reviewed `references/trusted-scanner.toml` by absolute path and do not use a target-owned baseline.
 - Treat scanner findings as security evidence, not a guarantee that a package is safe.
 - Ask before installing `plugin-scanner` if the command is not already available.

 Do not assume an existing `hol-guard` installation also provides the `plugin-scanner` command. If `pipx` is unavailable, point the user to the plugin-scanner installation instructions rather than silently changing their Python environment.
 
-### 2. Scan the target without executing it
+### 2. Resolve the reviewed scanner policy
+
+Resolve `references/trusted-scanner.toml` relative to this `SKILL.md` and use its absolute path as `TRUSTED_SCANNER_CONFIG`. This prevents a target-owned `.plugin-scanner.toml`, `.codex-plugin-scanner.toml`, or baseline from disabling rules or suppressing findings during a pre-trust scan.
+
+### 3. Scan the target without executing it
 
 For a repository or directory:
 
 ```bash
-plugin-scanner scan PATH --format markdown
+plugin-scanner scan PATH --config "$TRUSTED_SCANNER_CONFIG" --profile strict-security --format markdown
 ```
 
 For machine-readable results:
 
 ```bash
-plugin-scanner scan PATH --format json
+plugin-scanner scan PATH --config "$TRUSTED_SCANNER_CONFIG" --profile strict-security --format json
 ```
 
 For Agent Skill / plugin structure validation:
 
 ```bash
-plugin-scanner lint PATH
+plugin-scanner lint PATH --config "$TRUSTED_SCANNER_CONFIG" --profile strict-security
 plugin-scanner verify PATH
 ```
 
 Use the narrowest target path that contains the material the user asked to inspect.
+`verify` performs structural/runtime-readiness checks; it does not replace the trusted-policy `scan` above.
