Quality

Content

85%

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

The content is concise, well-structured, and presents a clear iterative workflow with an explicit checkpoint, fitting a simple instruction-only skill. Its main weakness is actionability: it delegates the concrete template and file-handling details to external materials rather than stating them in the body.

Suggestions

Add concrete specifics to the Draft step: where the .instructions.md file should be saved, its filename/location convention, and a brief outline of the template structure (or inline the key fields).

Give a one-line example of a generalized instruction derived from a user correction so the extraction step is copy-paste concrete.

State explicitly that the template and detailed principles come from `agent-customization`/`instructions.md` up front, so the single external dependency is signposted at the top rather than only at the end.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence, with no padding explaining what instructions files or conventions are; every section earns its place.

3 / 3

Actionability

Guidance is mostly concrete (extract corrections/patterns, ask specific clarifying questions, draft and save, iterate on weak parts) but omits key specifics such as where the file is saved, its naming, and the template structure, which are deferred to external materials.

2 / 3

Workflow Clarity

A clear three-step sequence (Extract, Clarify, Iterate) with an explicit feedback checkpoint ('Identify the most ambiguous or weak parts and ask') for a non-destructive, single-purpose task.

3 / 3

Progressive Disclosure

A short (under 50 lines), single-purpose skill with no local bundle files; it is cleanly sectioned and points one level deep to `instructions.md`/`agent-customization` rather than nesting references.

Description

50%

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 and third-person, clearly naming the artifact (.instructions.md) and the domain (project rules/conventions), but it omits any explicit "when to use this" trigger and offers only modest trigger-term coverage. It is competent but not distinctive enough to score at the top level.

Suggestions

Add an explicit 'Use when...' clause stating when to invoke this skill (e.g., 'Use when the user wants to capture a project rule, coding convention, or persistent preference as an instructions file').

Broaden trigger terms to include common user phrasings like 'coding standard', 'style guide', 'guideline', or 'always/never rules'.

Sharpen distinctiveness from `agent-customization` by clarifying that this skill specifically produces a .instructions.md file rather than general agent customization.

DimensionReasoningScore

Specificity

Names one concrete action ("Create an instructions file") and a concrete artifact type (".instructions.md"), but does not list multiple specific actions, so it stops short of the comprehensive level 3.

2 / 3

Completeness

Clearly states what the skill does but lacks any explicit "Use when..." trigger guidance; per the judging guidelines a missing when-clause caps completeness at 2.

2 / 3

Trigger Term Quality

Includes some natural terms a user would say ("instructions file", "rule", "convention") but misses common variations such as "coding standard", "style guide", or "guideline".

2 / 3

Distinctiveness Conflict Risk

The niche (creating .instructions.md files for project rules) is fairly specific, but the body's explicit reference to a sibling `agent-customization` skill indicates meaningful overlap risk with that related skill.
