Conciseness

The core sections are lean — gate tables, a compact anti-pattern table, and tight time budgets — but roughly ten lines of the closing 'About this skill' section are promotional padding (Synter links, utm campaigns) that earns no tokens for the task. The MECE definition also re-explains a concept Claude already knows, so the body sits at anchor 3 rather than 4.

Actionability

The body gives concrete, executable guidance: per-phase gate criteria ('Every rubric item is 10/10. Anything < 10 = fail'), a six-step numbered rubric-authoring procedure, an anti-pattern→correction table, and a copy-paste output format template. It falls short of anchor 5 because the worked example — the most instructive artifact — is delegated to 'examples/agent-bug-fix.md', which does not exist in the bundle.

Workflow Clarity

The five phases are explicitly sequenced with gate conditions per phase, a hard pass criterion (only 10/10 passes), and a built-in feedback loop: 'If Assess fails, narrow Plan to the gap … and re-run Execute + Assess. Repeat until the rubric holds.' The anti-patterns table adds error-recovery guidance, matching the top anchor exactly.

Progressive Disclosure

Section structure is good and the worked example is correctly pushed out of the main file, but the sole reference ('See examples/agent-bug-fix.md') points to a file that is not present in the bundle (no examples/, references/, scripts/, or assets/ directories exist). A clearly signaled reference that dangles, with all substantive content otherwise inline, lands at anchor 3.

Specificity

The description names the framework, all five phases ("Scope, Plan, Execute, Assess, Resolve") and two concrete mechanisms ("forcing an explicit MECE rubric" and "a Plan→Execute→Assess inner loop until the rubric passes"). It stops short of anchor 5 because it never states the concrete outputs (gates, rubric tables, scored assessments) or what the skill actually produces for the user.

Completeness

The 'what' is clear (enforces a MECE rubric and an inner Plan→Execute→Assess loop), but there is no 'Use when…' clause; "for any non-trivial agent task" is only a weak, implicit trigger. Per the rubric guideline, a missing explicit trigger clause caps completeness at 3.

Trigger Term Quality

The only plausibly natural phrase is "non-trivial agent task"; terms like "SPEAR loop", "MECE rubric", and "strong-start-weak-finish failure mode" are jargon a user would not naturally say. Common trigger variations ("bug fix", "feature", "refactor", "multi-step task") appear only in the body, not the description, keeping it at anchor 3 rather than 4.

Distinctiveness Conflict Risk

The named SPEAR framework and its distinctive vocabulary make it unlikely to trigger for an unrelated skill, satisfying anchor 4. It is not a 5 because "any non-trivial agent task" is a broad scope that overlaps general planning and execution-management skills.
