73%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.
An exceptionally actionable, well-sequenced orchestration guide: concrete commands, real validation checkpoints, eval→fix→re-eval feedback loops, and explicit failure recovery for a batch pipeline. Its weaknesses are repetition — the core editorial rules are restated 3–4 times across the Quality system, Quality bar, and Anti-patterns sections, plus stub sections kept only for a conformance test — and a monolithic structure that inlines a couple of topics that could live in reference files.
Suggestions
Consolidate the observe-never-prescribe / consultant-mode guidance that currently appears in 'What this does', 'Quality system (hard rules)', 'Quality bar', and 'Anti-patterns' into a single authoritative section and reference it from the others.
Merge the duplicate '## Anti-Patterns' header and the stub '## Contract' / '## Output Format' sections (which exist only for the conformance test) into one short conformance note to remove redundant tokens.
Move the children's-book variant and the deep-retrieval query-generation strategy into a references/ file, keeping SKILL.md as the overview with clearly signaled one-level-deep links.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly high-value operational content with no padding about concepts Claude already knows, but it could be tightened: the observe-never-prescribe/consultant-mode rule appears in at least four places (description, "What this does", "Quality bar", "Anti-patterns"), the pipe-table layout rule is explained three times, and the stub "## Contract", "## Output Format", and duplicate "## Anti-Patterns" sections exist purely for a conformance test. Fits the 3 anchor (mostly efficient, some unnecessary repetition); not 2 because the bulk is dense, earned, non-generic guidance. | 3 / 5 |
Actionability | Largely copy-paste ready: the EPUB extraction bash+python block, pdftotext command, the full `gbrain book-mirror` invocation with all flags, the eval-gate command with pass thresholds, and word-count quality checks. Minor gaps keep it at 4 rather than 5: the context-pack assembly heredoc contains non-executable "# ..." placeholders, and the PDF step defers the actual command to another skill's page. | 4 / 5 |
Workflow Clarity | A clearly labeled 6-step pipeline (ACQUIRE→EXTRACT→CONTEXT→ANALYZE→ASSEMBLE→PDF) is stated up front and then expanded in matching numbered sections, with explicit validation (chapter word-count quality check, output checklist, fact-check pass, cross-modal eval gate with a 7+ threshold) and genuine feedback loops ("If any dimension is below 6, rebuild with targeted fixes", failed-chapter retry with idempotency keys, "When it fails" exit-code handling). This is a batch operation and validation is thoroughly present, so the batch cap does not apply. | 5 / 5 |
Progressive Disclosure | No bundle files exist (references/, scripts/, assets/ are absent), so everything lives in one ~590-line SKILL.md; however, external materials (conventions/quality.md, conventions/brain-first.md, _brain-filing-rules.md, skills/brain-pdf, skills/cross-modal-review) are clearly signaled in a top conventions block and a Related-skills section, one level deep. Good structure with minor gaps — the children's-book variant and deep-retrieval query strategy are inline content that could be split into a reference file, and the duplicated conformance-test headers slightly muddy navigation. Not 5 because the monolithic file inlines some content that plausibly belongs in separate reference files; not 3 because references are clearly signaled and sections are well organized. | 4 / 5 |
