The description mentions creating a 'frozen snapshot of the validated prototype' and 'preventing production code from overwriting the validated reference artifact,' which names the domain and a couple of actions, but doesn't list multiple concrete steps or capabilities (e.g., how it locks, what format, what artifacts).

The description explicitly answers both 'what' (creates a frozen snapshot of the validated prototype before development begins, preventing production code from overwriting the validated reference artifact) and 'when' (with an extensive list of trigger phrases and the condition 'when the user says...' or 'wants to create a frozen snapshot').

The description provides extensive natural trigger phrases including 'prototype lock', 'lock prototype', 'freeze prototype', 'preserve prototype', 'snapshot prototype', 'protect prototype', 'archive prototype', 'save the prototype', 'lock the design', 'freeze the design', and many variations users would naturally say.

The skill occupies a very specific niche—locking/freezing a validated prototype artifact—with highly distinctive trigger terms like 'prototype lock' and 'freeze prototype' that are unlikely to conflict with other skills.

The skill is extremely verbose at ~250+ lines. It over-explains many concepts Claude already understands (e.g., what frameworks to detect, how cp -r works, how git tags work). The framework detection table, detailed copy strategy explanations, and extensive error handling scenarios could be significantly condensed. Many conversational prompts are spelled out verbatim when Claude could generate appropriate messaging from brief instructions.

The skill provides concrete steps and specific commands (git tag, cp -r, chmod +x), but relies heavily on template files referenced via ${CLAUDE_PLUGIN_ROOT} paths that are not provided in the bundle. The actual executable content (guard scripts, hook templates, lock report templates) is absent, making the skill incomplete without those references. Framework-specific build commands are described but not fully spelled out.

The 9-step workflow is clearly sequenced with explicit validation checkpoints (Step 4 validates the build, Step 5 asks user to confirm access), feedback loops (retry up to 3 times on build failure), and clear user confirmation gates at Steps 1, 2, 5, and 8. Error recovery paths are well-defined throughout, and destructive operations have appropriate safeguards.

The skill references three external template files (lock-report-template.md, prototype-guardrail-rules.md, pretooluse-hook-template.json) which is good progressive disclosure design, but none of these bundle files are provided, making it impossible to verify their content or accuracy. The main SKILL.md itself is monolithic — the framework detection table, agent invocation guide, and error handling could potentially be split into reference files to reduce the main file's length.
