Conciseness

The ~196-line body is mostly valuable specialized operational knowledge Claude does not already know, but it carries notable redundancy: the "When to Use" section appears twice (top and bottom) and the Key Edge Cases re-summarize material already covered in Core Knowledge (Uri, basis risk, ratchet), so it could be tightened; not a 4 because the duplication exceeds minor over-explanation.

Actionability

Provides concrete, specific guidance — numbered decision frameworks with explicit thresholds ("simple payback < 5 years"), a load-factor formula, RFP steps ("issue RFPs to 5–8 qualified REPs"), and ready-to-use communication scripts — but a meaningful portion (Utility Bill Anatomy, Market Structures) is explanatory reference knowledge rather than direct executable steps, keeping it below 5.

Workflow Clarity

Multi-step processes (Procurement Strategy Selection, PPA Evaluation, Demand Charge Mitigation ROI, Market Timing) are clearly sequenced, and the escalation protocols plus performance indicators function as monitoring checkpoints; however explicit validate→fix→retry feedback loops are largely absent, so it stops at 4 rather than 5. No destructive/batch cap applies.

Progressive Disclosure

The body is an overview that clearly signals one-level-deep references to three real bundle files (decision-frameworks.md, edge-cases.md, communication-templates.md) via markdown links and an Additional Resources section, with content appropriately split and easy to navigate, matching the top anchor.

Specificity

Lists five concrete capability areas — "electricity and gas procurement, tariff optimisation, demand charge management, renewable PPA evaluation, and multi-facility energy cost management" — giving comprehensive domain coverage, though the "Codified expertise for" framing and noun-phrase list lack explicit action verbs, keeping it below a 5.

Completeness

The description clearly answers "what" via its enumerated capabilities but contains no "Use when..." clause or equivalent explicit trigger guidance, which per the rubric caps completeness at 3; it is not a 4 because the "when" is entirely absent rather than weakly implied.

Trigger Term Quality

Contains multiple natural domain terms a user would say ("energy procurement", "tariff optimisation", "demand charge management", "PPA evaluation"), but misses common synonyms and phrasings like "power purchase agreement" spelled out, "utility bills", or "reduce energy costs", so not a 5.

Distinctiveness Conflict Risk

The niche is highly specific — commercial/industrial energy procurement, PPAs, demand charges, capacity tags — with distinct triggers and minimal overlap risk against other skills, matching the anchor for a clear niche.
