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.
A tightly engineered process skill: the four-stage workflow is unambiguous, gated by hard refusals and early exits, and closes with real verification loops plus a mermaid flowchart. Its weaknesses are stylistic density — repeated round-numbered provenance justifications that a mid-tier executor does not need — and commands referenced by name rather than given verbatim.
Suggestions
Trim or relocate the round-numbered provenance asides (round 11/13/15/12 citations in the intro, Stage 1 scope stop, Stage 4 judge step, and Bounds) into a single short 'why these gates exist' note or a separate reference file; the executing model needs the rule, not the measurement history.
Name the actual invocations where the body currently gestures at tooling: give the check-script's command or path, and the literal fable-judge suite-mode / headless-harness invocation, so a lesser model does not have to discover them.
Consider splitting the red-lines enumeration and the [observed]/[covenant]/[v1.4] tag legend into a short reference file to keep SKILL.md as a lean overview plus workflow.

Conciseness | The core instructions are dense and imperative with no padding, but the body repeatedly pauses to justify its own design with provenance asides — 'two Fable 5 agents were asked, with zero process hints... (`eval/results/round11-observed-traces.json`)', 'a weak model blew straight past it, mid-build momentum winning over restraint (round 15)', 'bare Haiku called an unverified bundle "production-ready", round 13'. These measured-history parentheticals recur across the intro, Stage 1, Stage 4, and Bounds, and could be tightened or moved without loss to the executor. Not a 2: none of it explains concepts Claude already knows, and every aside is repo-specific fact, not generic filler. | 3 / 5 |
Actionability | Concrete, executable instruction throughout: 'read every adapter in `references/domains/` plus the governing docs', 'Keep the section headers exactly (CI greps them)', 'GROUND-TRUTH.md carries the task prompt, the trap, 0/1/2 caps, and ideal behavior', and a complete wiring list of routing surfaces. Not a 5 because commands are referred to rather than given verbatim ('Run the repo's own check script' without naming it; 'via fable-judge suite mode, or the headless harness' without an invocation), and the Stage 1 discussion questions are deliberately adaptive rather than a fixed list. | 4 / 5 |
Workflow Clarity | A clearly sequenced 4-stage pipeline with hard early exits (red-line refusal, scope stop, 'No web access means no trustworthy bundle: say so and stop') and explicit validation checkpoints with feedback loops: 'Run the repo's own check script; fix what fails', 'if the trap shows no difference, report the bundle unproven', and 'A bundle that fails the judge is not done'. The mermaid flowchart restates the full sequence including the failure branches. This matches the top anchor: clear sequence, explicit validation steps, error-recovery loops, and a checklist of the four deliverables ('all four, or not done'). | 5 / 5 |
Progressive Disclosure | No bundle files exist (no references/, scripts/, or assets/ directories), so this is a single-file skill whose named paths (`references/domains/TEMPLATE.md`, `references/flowcharts.md`, `eval/scenarios/`) point into the target repo's install, not the skill's own bundle — none are verifiable here. The ~65-line body is well-sectioned (What it produces, Stages 1-4, flowchart, Bounds) with clearly signaled external pointers. Not a 5: it exceeds the under-50-line simple-skill allowance and inlines material (the red-lines list, the [observed]/[covenant]/[v1.4] provenance legend) that could sit in a reference file, though the single-file layout is defensible for a process skill. | 4 / 5 |
