Quality

Content

77%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is highly actionable with clear, validated workflows and copy-paste commands, but leans monolithic and repeats some alias restatements. Splitting reference material into bundle files and trimming redundancy would improve token efficiency.

Suggestions

Trim repeated alias restatements (e.g. the recurring "# or the long form: ..." notes) since the aliases table already covers them.

Move the 'Writing good facts' and 'Domain vocabulary' sections into reference files (e.g. references/writing-facts.md) and link to them, so the main SKILL.md stays an overview.

Consolidate the duplicate lifecycle/workflow command blocks (start-of-work, track-progress, maintain-accuracy) into a single canonical sequence to reduce repetition.

DimensionReasoningScore

Conciseness

Mostly efficient with command-focused sections, but restates aliases ("# or the long form: ...") and repeats the same lifecycle/workflow patterns across sections; some tightening is possible.

2 / 3

Actionability

Provides fully executable, copy-paste-ready commands throughout (e.g. "facts add 'users can sign up' --section features/auth --tags draft") with concrete arguments and examples for every operation.

3 / 3

Workflow Clarity

Sequences multi-step agent workflows with explicit validation checkpoints ("facts ll" then "facts check" as the primary feedback loop) and a manual-fact verification procedure, with the lifecycle flow @draft -> @spec -> @implemented made explicit.

3 / 3

Progressive Disclosure

No bundle files exist and the content is a single well-sectioned file, but it is a monolithic ~150-line document; sections like the domain vocabulary and writing-good-facts guidance could be offloaded to reference files.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is concise, specific, and supplies an explicit trigger clause covering both what the skill does and when to invoke it. It avoids fluff and reads in third person, matching the top reference examples.

DimensionReasoningScore

Specificity

Enumerates multiple concrete actions — "Install, check, list, add, edit, remove, and lint facts" — rather than vague language.

3 / 3

Completeness

Explicitly answers both what ("Manage .facts files ... via the CLI") and when ("ALWAYS read this skill when the user mentions facts in any capacity").

3 / 3

Trigger Term Quality

Uses natural user-facing terms ("facts", "check", "add", "edit", "remove", "lint") a user would actually say, anchored by "when the user mentions facts in any capacity."

3 / 3

Distinctiveness Conflict Risk

The "facts" / ".facts files" niche and its dedicated trigger terms are clearly distinct and unlikely to collide with other skills.
