Quality

Content

82%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 tightly structured, highly actionable walkthrough with concrete code at every step and sensible validation checkpoints. Its main weaknesses are an implicit rather than explicit error-recovery loop and reference material that could be offloaded to a bundle file.

DimensionReasoningScore

Conciseness

The body is mostly lean — tables of properties, code blocks, and terse instructions — assuming Claude's knowledge of LLVM; a few explanatory lines (e.g. the name-derivation note) could be trimmed, so it is efficient with minor over-explanation.

4 / 5

Actionability

It provides copy-paste-ready TableGen, cmake, C++ IRBuilder, verifier, lit, and InstCombine code blocks that cover the common cases with concrete, executable guidance.

5 / 5

Workflow Clarity

Steps 0–7 are clearly sequenced with checkpoints (rebuild intrinsics_gen, run lit, '-passes=verify' before optimization passes), but the validate→fix→retry feedback loop is implied rather than made explicit, leaving a minor validation gap.

4 / 5

Progressive Disclosure

Content is well organized into clearly headed sections (Step 0–7, common mistakes) with easy navigation, but the property and type-token reference tables are inlined rather than split into a separate reference file, a minor organization gap.

Description

75%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 specific, actionable, and well-scoped to a distinct LLVM niche, but it omits any explicit 'when to use' trigger guidance, capping its completeness. Adding a 'Use when...' clause would lift it into the top tier.

Suggestions

Append an explicit trigger clause, e.g. 'Use when the user asks to add, register, or define a new llvm.* intrinsic in LLVM.'

Include a natural synonym such as 'builtin' or 'built-in function' alongside 'intrinsic' to broaden trigger coverage.

Mirror the body's existing 'If the user only needs to call an existing intrinsic from a frontend' boundary into the description to reduce false triggers.

DimensionReasoningScore

Specificity

The description lists five concrete actions ('TableGen definition, header regeneration, IRBuilder call-site usage, verifier rules, and lit testing'), giving comprehensive coverage of the skill's capabilities rather than vague language.

5 / 5

Completeness

It clearly answers 'what' but contains no 'Use when...' clause or equivalent explicit trigger guidance in the description itself, which per the rubric caps completeness at 3 even though the what is well specified.

3 / 5

Trigger Term Quality

The phrase 'Add a new LLVM IR intrinsic in LLVM 22' is a natural term a user would say, but coverage relies on domain jargon (TableGen, IRBuilder, lit) and lacks synonyms or file-extension variants, so a few natural terms are missing.

4 / 5

Distinctiveness Conflict Risk

'Add a new LLVM IR intrinsic in LLVM 22' is a clear, narrow niche with distinct triggers and minimal risk of firing for an unrelated skill.
