⚠ TRIGGER-03 Invocation cues in the description

cpp-expert.md:1description will match user requests → no explicit cue ('use when …', 'triggers on …', quoted user phrases) found

Pure what-it-does prose — the model has to guess when to invoke it.

Expert in writing high-quality, efficient, and modern C++ code.

Fix State the trigger explicitly: 'Use when the user says "…", "…", or wants to …'.

⚠ TRIGGER-02 Description long enough to anchor invocation

cpp-expert.md:1description will trigger invocation → 63 chars — under the ~100-char reliable-trigger band

Description is thin — likely under-specifies when to invoke.

Expert in writing high-quality, efficient, and modern C++ code.

Fix Add the concrete use case and user phrasing (e.g. 'Use when the user says …').

⚠ SAFETY-02 allowed-tools least-privilege

cpp-expert.md:1no `tools` declared → the agent inherits every tool, including Bash

Subagents without a `tools` list get unrestricted tool access.

Fix Declare a scoped `tools:` list with only what the agent needs (e.g. `tools: Read, Grep, Glob`).

Partial grade — some applicable rubric categories were not scored on this scan (e.g. LLM-assisted checks without a key) and are excluded from the overall.
