Conciseness

The body is dense and assumes Claude's competence with no padding or explanations of known concepts; minor trimming is possible since the Instructions section restates most of sprint-phases.md and the Resources section repeats skills already cited inline.

Actionability

Provides concrete commands ("/sprint:new", "/sprint"), exact file paths (".claude/sprint/[N]/specs.md", "api-contract.md"), named agents ("python-dev", "qa-test-agent"), and a five-row error table with causes and solutions; minor gaps remain because the SPAWN REQUEST format and spec authoring are deferred to other skills.

Workflow Clarity

Phases 0–5 are explicitly sequenced with a dedicated testing validation phase, an architect conformity-review decision point, and a feedback loop with a 5-iteration convergence cap that triggers manual intervention — matching the anchor for clear sequence with explicit validation and error-recovery loops.

Progressive Disclosure

sprint-phases.md is well signaled via "${CLAUDE_SKILL_DIR}/references/sprint-phases.md" and one level deep, but the bundle's errors.md and examples.md are never referenced from the body, which instead inlines its own Error Handling table and Examples section — references present but not clearly signaled, and content that should be separate is inline.

Specificity

The description names the domain and one concrete action ("wants to understand the sprint execution model and its convergent diffusion approach") and enumerates six topic areas, but lists no concrete capabilities; the garbled opening ("Execute this skill should be used") and filler ("Use when appropriate context detected. Trigger with relevant phrases based on skill purpose.") add vagueness.

Completeness

The "when" is explicit and rich via the quoted trigger phrases, and the "what" is identifiable (explaining the sprint execution model and its convergent diffusion approach), but the what is implied from user intent rather than stated as a capability, so it falls short of the fully explicit anchor 5.

Trigger Term Quality

Includes multiple natural user phrasings — "how sprints work", "sprint phases", "iteration workflow", "convergent development", "sprint lifecycle", "when to use sprints" — with good synonym variation, though common variants like "sprint process" or "agile sprints" are missing.

Distinctiveness Conflict Risk

Triggers like "sprint lifecycle" and "convergent development" are clearly niche, but the generic phrase "iteration workflow" creates minor overlap risk with general workflow or iteration skills, matching anchor 4 rather than 5.
