81%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-constructed instruction skill: an unambiguous 8-step workflow with genuine validation gates (Unknown/NEEDS_INPUT instead of pass-by-default), concrete thresholds, and executable connector commands. The main costs are the four-fold repetition of the scope guard and a web of cross-skill references whose targets fall outside this bundle.
Suggestions
State the scope guard (no EQS computation, no veto enforcement, trend belongs to list-hygiene-monitor) once in the intro and once in the Scope guard section, and cut the restatements in step 1, step 8, and the S2/hygiene steps to a short pointer — this would recover conciseness without losing the boundary.
Verify or inline-fallback the connector commands: scripts/connectors/doh.py and resend.py are referenced as executable but the scripts/ directory is not part of this bundle, so a missing file breaks the copy-paste path.
Move the per-profile S-weight table (0.30/0.20/0.35/0.25) and the spam-content/link/render criteria into references/deliverability-checklist.md, keeping only the profile names and red-line thresholds in SKILL.md, so the body is a leaner overview pointing one level deep.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense and assumes Claude's competence — no basic DMARC/reputation concept explanations, and specifics like the 0.1% complaint red line and per-profile weights (0.30/0.20/0.35/0.25) earn their tokens. However, the scope guard (this skill does NOT compute EQS or enforce vetoes; the trend belongs to list-hygiene-monitor) is restated at least four times — intro paragraph, step 1, step 8, the 'Scope guard' paragraph, and Next Best Skill — which is more than the 'minor instances' of anchor 5 but better than the 'unnecessary explanation' of anchor 3. | 4 / 5 |
Actionability | Gives two copy-paste-ready commands ('python3 "${CLAUDE_PLUGIN_ROOT}/scripts/connectors/doh.py" auth <domain> [--selector <esp-dkim-selector>]' and 'resend.py domains'), exact thresholds, typed profiles, and a deterministic state machine. It falls short of anchor 5 because the referenced connector scripts and most cross-referenced files (../../../references/send-benchmark.md, CONNECTORS.md, skill-contract.md) are not present in the bundle, so the commands' executability cannot be fully confirmed, and the workflow inputs remain placeholders ('[paste/path]', '[name]'). | 4 / 5 |
Workflow Clarity | Eight clearly sequenced numbered steps with explicit validation checkpoints throughout: missing DMARC RUA or seed test forces the item to 'Unknown' and the run to 'NEEDS_INPUT — never pass-by-default', a 'Done when' contract, defined S1 flag outcomes, and Termination rules (stop on veto-candidate or Unknown). This matches anchor 5's 'clear sequence with explicit validation steps; feedback loops; checklists' — the detailed checklist is split into references/deliverability-checklist.md, which exists and matches its description. | 5 / 5 |
Progressive Disclosure | Good structure: an overview body with clearly labeled sections, a Reference Materials list, and the detailed checklist correctly split into the bundle's one real file, references/deliverability-checklist.md, referenced one level deep. It does not reach anchor 5 because most other references point outside the skill directory (../../../references/*, ../../deliver/email-quality-auditor, ../list-hygiene-monitor, protocol/consent-registry) and cannot be resolved from the bundle, and some step-level detail (e.g., per-profile benchmark rows) is inlined where the checklist file could carry it. | 4 / 5 |
