Lists multiple specific concrete actions: creates/queries expertise profiles, increments file-familiarity counters, ranks candidate agents by recency and task-area match. These are precise, actionable capabilities.

Clearly answers both what (creates/queries profiles, increments counters, ranks agents) and when (explicit 'Use when...' clause with four distinct trigger scenarios: deciding agent assignment, checking last worker, recording outcomes, assigning by performance).

Includes natural trigger terms users would say: 'which agent should handle a file', 'who last worked on a module', 'recording task outcomes', 'assigning work based on past performance'. Also mentions specific artifacts like AGENT-EXPERTISE.md and file-familiarity counters.

Highly distinctive niche focused on agent expertise tracking and work assignment. References a specific file (AGENT-EXPERTISE.md) and domain-specific concepts like file-familiarity counters and agent ranking, making it very unlikely to conflict with other skills.

The content is lean and efficient. It uses tables for triggers, provides only necessary code examples, and doesn't explain concepts Claude already knows. Every section serves a clear purpose without padding.

Provides executable bash/awk commands for updating expertise files, concrete grep commands for retrieval, specific entry formats, and a clear example prompt block. The code is copy-paste ready and covers both reading and writing operations.

The workflow section has clear sequencing (before delegating → after task → on failure) with explicit validation checkpoints at each step. Each step includes a 'Validate' sub-step specifying what to check, and the pruning section also includes validation.

References KNOWLEDGE-GRAPH.md appropriately for detailed content, but the bundle has no files to support this reference. The skill itself is well-structured with clear sections, but the referenced file doesn't exist in the bundle, which weakens navigation reliability.
