Quality

Content

32%Weight 40%Scale 1-5

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

The body is a well-organized but entirely unpopulated template: good section scaffolding with placeholders everywhere. Structure (progressive disclosure, conciseness) is sound, but actionability and workflow clarity fail because no real instructions, commands, or validation conditions exist. The skill is unusable as-is and needs its brackets filled with concrete, executable content.

Suggestions

Replace every bracketed placeholder with concrete, executable guidance — real commands in the Verification Protocol (e.g. an actual command and the exact output to check) and real steps in each Workflow section.

Populate the BLOCKED gates with specific, checkable conditions so validation is enforced rather than implied, which would raise workflow clarity.

Fill the Anti-Rationalization table with the actual excuses that arise for this task, or move it to a reference file to keep SKILL.md as a lean overview.

DimensionReasoningScore

Conciseness

At ~90 lines with no concept explanations, no padding, and no tutorials, the body is structurally efficient, but every content token is a bracketed placeholder (e.g. the 5-row "[Common excuse N]" table), so the token spend buys scaffold, not guidance — between anchors 3 and 4 rather than the lean anchor 5.

3 / 5

Actionability

All instructions are placeholders — "[Specific instruction]", "[What command to run as proof]", "[Brief explanation]" — with no concrete code, commands, or examples anywhere, matching anchor 1 ("Entirely vague or abstract; no concrete code or commands").

1 / 5

Workflow Clarity

A sequence skeleton exists (Step 1/2/3, "**BLOCKED** until [condition]", a Verification Protocol section), so steps are not missing as in anchor 1, but the steps themselves are undefined placeholders and validation conditions are empty, matching anchor 2 ("Rough sequence present but many gaps; steps poorly defined; validation absent").

2 / 5

Progressive Disclosure

No bundle files exist and none are needed at this size; the body has clear, well-ordered, easy-to-navigate sections (When to Use → Workflow → Verification Protocol → Rules → Output), matching anchor 4 ("Good structure; most content is appropriately placed; minor organization gaps") — not 5 because the inlined Anti-Rationalization table and Rules would belong in reference files in a fleshed-out skill.

Description

0%Weight 40%Scale 1-5

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 an unpopulated template placeholder that communicates nothing about what the skill does or when to use it. It fails all four dimensions at the lowest anchor. The skill needs a real description with concrete capabilities, a domain, and natural trigger phrases before it can be discovered or invoked correctly.

Suggestions

Replace the placeholder with concrete actions in third person, e.g. "Extract text and tables from PDF files, fill forms, merge documents" — name the domain and 3-4 specific capabilities.

Keep and populate the "Use when..." clause with natural phrases a user would actually say, including synonyms and file extensions (e.g. "Use when working with PDF files, .pdf, forms, or document extraction").

Add distinguishing details (file types, specific operations) so the description cannot conflict with neighboring skills in the library.

DimensionReasoningScore

Specificity

The description is an unfilled template placeholder — "[specific triggering conditions - what symptom or situation activates this skill]" — naming no domain and no concrete actions, making it vaguer than even the anchor-1 example "Helps with documents".

1 / 5

Completeness

A "Use when" frame exists but its content is a placeholder and no "what" is stated at all, so both what and when are extremely vague — the anchor-1 condition; anchor 2 requires at least a vague real 'what' or a real 'when', neither of which is present.

1 / 5

Trigger Term Quality

There are no natural keywords a user would say; the text is bracketed template instruction language rather than any real trigger term, matching the anchor for "no natural keywords; only technical jargon or entirely generic language".

1 / 5

Distinctiveness Conflict Risk

With no domain, capability, or trigger content, the description is entirely generic and indistinguishable from virtually any other skill, matching the anchor-1 example "Helps with code and documents".
