77%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-structured, actionable pre-flight skill with an explicit validated workflow and clean progressive disclosure. Its main weakness is repetition: the same scope-guard boundary is asserted in four places, inflating tokens without adding clarity.
Suggestions
Consolidate the SEND-S / EQS scope-guard into a single canonical statement (e.g., keep it once in the Skill Contract and reference it from the intro, step 8, and Next Best Skill) to remove the four-way restatement and tighten conciseness.
Pull the two or three most decisive S1 pass/partial/veto-candidate criteria (e.g., 'no DMARC record → veto-candidate', 'p=none + aligned/passing → Partial') inline into step 2 so the core decision is actionable without opening the checklist, raising actionability toward 5.
In the repeated 'Not for…use X' routing, state each sibling-skill handoff once in Next Best Skill rather than re-deriving it in the Data Sources, step 6, and step 7 prose.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Assumes Claude's intelligence (no padding about what SPF/DKIM/DMARC are) and concrete thresholds earn efficiency, but the SEND-S/EQS scope-guard boundary is restated four times (intro, step 8, a dedicated 'Scope guard' block, and Next Best Skill) — noticeable redundancy that could be tightened to one canonical statement. | 3 / 5 |
Actionability | Gives executable commands ('python3 …/connectors/resend.py domains', 'python3 …/connectors/doh.py auth <domain> [--selector …]'), specific numeric thresholds (spam-complaint <0.1%, profile weights 0.30/0.20/0.35/0.25) and copy-pasteable Quick Start prompts; not 5 because the detailed per-check criteria live in the referenced checklist rather than inline. | 4 / 5 |
Workflow Clarity | An 8-step numbered sequence with explicit validation checkpoints at each step (Unknown → NEEDS_INPUT, never pass-by-default, 100% applicable-coverage gate before scoring) plus termination rules (visited-set, max-depth:3, ambiguity stop) and a stop-on-veto-candidate feedback loop; this read-only QA skill has no destructive/batch op, so the cap does not apply. | 5 / 5 |
Progressive Disclosure | Clear sectioned overview (Quick Start, Skill Contract, Data Sources, Instructions, Save Results, Reference Materials, Next Best Skill) with one-level-deep, well-signaled references; the in-bundle references/deliverability-checklist.md is a real file and cross-skill links are cleanly enumerated rather than nested. | 5 / 5 |
