Conciseness

The body is dense but mostly every token earns its place; however the niche-distinction framing repeats across the intro, the closing line, and the Reference Materials/Next Best Skill sections, so it could be tightened. It sits between the 'mostly efficient' (2) and 'lean and efficient' (3) anchors.

Actionability

Provides copy-paste-ready commands (the ledger.py record/trend invocations), an explicit pace formula, a four-value verdict taxonomy, and labeled-figure rules — fully executable guidance rather than vague direction.

Workflow Clarity

Six numbered, sequenced steps with explicit validation checkpoints — fix the curve before reading spend, confirm learning-phase before acting, fire/hold gating on the band — giving clear feedback/guardrail logic for a risky reallocation operation.

Progressive Disclosure

Sections are well-organized with one-level-deep reference links, but every referenced file points outside the skill bundle (../../../…) and none are present in ./references, ./scripts, or ./assets, so the actual bundle structure is empty while the body implies a rich reference tree.

Specificity

Lists multiple concrete outputs — "a spend-vs-target-curve read, learning-phase status, an over/under-delivery call, and a reallocation trigger" — matching the rubric's top anchor for multiple specific concrete actions.

Completeness

Explicitly answers what it returns and when to use it via a "Use when…" clause, plus what it is not for — both what and when are clearly stated with explicit triggers.

Trigger Term Quality

Quotes natural phrases users would say ("check pacing", "am I over/under-spending", "is this campaign on track to hit budget", "why did spend spike/stall mid-flight"), giving good coverage of natural terms.

Distinctiveness Conflict Risk

Explicitly carves a clear niche and names three sibling skills it is not (budget-optimizer, bid-strategy-planner, ad-account-auditor), making it unlikely to trigger for the wrong skill.
