Quality

Content

68%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 delivers concrete, mostly executable code for a customer support agent with a clear agentic loop and tidy structure. Its main weaknesses are the lack of validation/verification checkpoints around state-changing actions and the placeholder tool stubs.

Suggestions

Add a validation/verification checkpoint after tool execution (e.g., confirm ticket fields before create_ticket, and verify escalation criteria before escalate_to_human) so the agent loop includes an explicit feedback loop rather than blindly returning tool output.

Replace the undefined stub functions in execute_tool with concrete, runnable implementations or clearly mark them as integration points requiring user-supplied functions.

Parameterize the hardcoded model 'claude-opus-4-6' (e.g., a MODEL constant or config value) to avoid embedding a time-sensitive, version-specific literal in the skill body.

DimensionReasoningScore

Conciseness

The body avoids preamble about what a support agent is and stays mostly lean code plus a compact table, but the hardcoded model literal 'claude-opus-4-6' and placeholder comments add minor noise, fitting the 4 anchor rather than 5.

4 / 5

Actionability

Real tool schemas, a system prompt, an agent loop, and a dispatch function provide mostly executable guidance, but execute_tool calls undefined functions with 'implement with your docs' placeholders, leaving minor gaps that keep it from a 5.

4 / 5

Workflow Clarity

The agentic loop is coherently sequenced, but ticket creation and human escalation are batch/ destructive-style actions affecting a customer's account state and the loop has no validation, error-recovery, or verification checkpoint; per the rubric this caps workflow clarity at 3.

3 / 5

Progressive Disclosure

Section headers (Overview, Agent Architecture, Tool Implementation Stubs, Quick Reference) and a reference table give good structure, but all content is inlined with no bundle files or one-level-deep references, so it fits the 4 anchor rather than 5.

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 clearly answers both what the skill does and when to use it, with concrete capabilities and a natural trigger phrase. It is strong but stops short of comprehensive synonyms, multiple trigger phrases, and full coverage of in-skill actions.

DimensionReasoningScore

Specificity

Names the domain (customer support agent) plus three concrete capabilities — 'knowledge base lookup', 'ticket creation', and 'human escalation logic' — matching the 'several specific actions; minor gaps' anchor; it omits other in-skill actions like order status, so it is not a 5.

4 / 5

Completeness

It states both the 'what' (KB lookup, ticket creation, escalation) and the 'when' ('Use this skill when building a customer support agent'), but the trigger is a single phrase rather than multiple concrete trigger phrases, fitting the 4 anchor rather than 5.

4 / 5

Trigger Term Quality

'building a customer support agent' is a phrase a user would naturally say, supplemented by 'knowledge base lookup', 'ticket creation', and 'human escalation'; coverage is good but lacks common synonyms like 'help desk' or 'chatbot', so not 5.

4 / 5

Distinctiveness Conflict Risk

'Customer support agent' with ticket creation and escalation is a fairly distinct niche with low conflict risk, though it could mildly overlap with generic agent-building skills, keeping it at 4 rather than 5.
