Conciseness

The body is efficient — no explanations of concepts Claude already knows; sections like "Overview" (2 sentences) and the Error Handling table are tight. Minor trimmable bulk remains: the Examples section inlines ~40 lines of SPAWN REQUEST/AGENT REPORT blocks that largely duplicate references/examples.md, and Resources pads with non-path items like "Sprint plugin README for agent architecture overview". Matches anchor 4; not 5 because of that duplicative example bulk, not 3 since nothing over-explains known material.

Actionability

Fully concrete, copy-paste-ready formats cover the common cases: a complete SPAWN REQUEST block ("Agent: python-dev / Specs: .claude/sprint/1/backend-specs.md / Contract: ... / Scope: Authentication endpoints only"), a full AGENT REPORT template ("Files Modified: src/auth/routes.py... Tests: 12 passed, 0 failed / Conformity: ..."), sequencing via "Run After: python-dev, nextjs-dev", and a cause/solution error table. Per the rubric's instruction-skill note, absence of code is not penalized when guidance is this actionable — this matches anchor 5.

Workflow Clarity

The six numbered Instructions give a clear sequence with an explicit feedback loop in step 5 ("The architect decides whether to iterate (re-spawn with narrowed specs) or advance to the next phase") and recovery paths in the error table ("the orchestrator pauses after 5 iterations"). Not 5: the validation checkpoint is underspecified — what the architect verifies in a report (required fields, conformity evidence) before iterating or advancing is left implicit, which is the "minor validation gaps" of anchor 4 rather than anchor 5's explicit validation steps.

Progressive Disclosure

Of the three bundle files, only one is signaled — "${CLAUDE_SKILL_DIR}/references/ui-test-report.md" (referenced in Instructions step 6 and Resources, and it exists) — while references/errors.md and references/examples.md are never linked from the body, leaving them undiscoverable. Meanwhile the inlined Examples section duplicates content that belongs in examples.md. This matches anchor 3 ("content that should be separate is inline" plus poorly integrated references); not 4 because two orphaned bundle files exceed "minor organization gaps", not 2 because section structure and the one existing reference path are clear.

Specificity

The description names its domain ("how agents coordinate within the sprint system") but states no concrete actions — phrases like "Execute this skill should be used when the user asks about" and "needs to understand how agents coordinate" never say what the skill does (e.g., defining SPAWN REQUEST formats, structuring agent reports, partitioning parallel work). This matches anchor 2 ("Names the domain but actions are minimal or generic"); it is not 3 because no concrete capability is listed anywhere.

Completeness

The 'when' is explicit (the quoted trigger phrases), but the 'what' is only vaguely implied — the sole capability statement is "needs to understand how agents coordinate within the sprint system", with no mention of the coordination protocol, spawning, or report collection the skill actually defines. It sits between anchor 3 and 4; the weak 'what' pulls it down to 3 rather than 4, and it is above 2 because both a what (vague) and a when (explicit) are present.

Trigger Term Quality

Quoted triggers — "SPAWN REQUEST format", "agent reports", "agent coordination", "parallel agents", "report format", "agent communication" — give good natural keyword coverage a user in this ecosystem would say. Not 5: common synonyms like "multi-agent", "spawn agents", or "agent orchestration" are missing, and the tail is vacuous filler ("Use when appropriate context detected. Trigger with relevant phrases based on skill purpose.") rather than trigger content.

Distinctiveness Conflict Risk

Triggers like "SPAWN REQUEST format" and "within the sprint system" occupy a clear niche, but broader terms ("parallel agents", "agent coordination", "agent communication") could overlap with other agent-orchestration or multi-agent skills. This matches anchor 4 ("Mostly distinct; minor overlap risk with closely related skills"); not 5 because several triggers are generic to the agent-skills category.
