The body is lean and list-driven with no concept-explanation padding; Principles (positive rules) and Anti-Patterns (negative rules with WHY rationale) are complementary rather than duplicative, and every command and example earns its place.

Provides a concrete loader command, an exact Metrics Summary format with field names and sample numbers, and copy-paste usage examples; the analysis steps give specific categories and sub-dimensions rather than vague direction.

A clear 7-step sequence is paired with error-recovery guidance in Gotchas (missing duration_seconds, unreadable session files -> partial report), giving feedback loops appropriate for this batch read operation.

Sections are well-organized and the reference is well-signaled and one level deep, but references/reference.md and scripts/retrospect-load-sessions.sh are cited in the body yet absent from the bundle, breaking navigation.

Names the collaboration-analysis domain and several actions ('Analyze collaboration patterns', 'compute metrics', 'reviewing collaboration quality', 'analyzing human-AI interaction'), but the verbs repeat at a high level rather than listing distinct concrete operations like the anchor-3 'extract, fill, merge'.

Clearly states what it does ('Analyze collaboration patterns (HOW) and compute metrics from captured sessions') and when to use it ('Use when reviewing collaboration quality...') with explicit triggers, answering both what and when.

Explicit triggers 'retrospect collab', 'collaboration analysis', 'session patterns', and 'how am I collaborating' are natural phrases a user would actually say, giving good coverage.

The HOW-focused collaboration-analysis niche with distinct triggers ('retrospect collab', 'how am I collaborating') carves a clear niche unlikely to trigger for the wrong skill.
