Quality

Content

72%

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

This is a concise, well-structured architectural guidance skill that clearly communicates constraints and anti-patterns for error envelope consistency. Its main weakness is the lack of concrete code examples showing the actual implementation pattern (e.g., what the enriched ServiceResponse looks like, what the serialized JSON output should contain). Adding even one before/after code snippet would significantly improve actionability.

Suggestions

Add a concrete code example showing how to stamp `command` and `sessionId` on `ServiceResponse` in `ProcessAsync()`, even a minimal snippet.

Include an example of the expected serialized error JSON output so implementers can verify correctness across MCP and CLI.

Add a brief verification step (e.g., 'Confirm both MCP and CLI error outputs contain `command` and `sessionId` fields by running existing integration tests') to improve workflow clarity.

DimensionReasoningScore

Conciseness

Every line serves a purpose. No unnecessary explanations of what MCP, CLI, or service boundaries are. The patterns and anti-patterns are stated directly without preamble.

3 / 3

Actionability

The skill provides clear architectural guidance and references specific files, but lacks concrete code examples showing how to enrich failures, what the JSON output should look like, or what the request-context helper pattern looks like. The examples section lists file paths rather than showing executable code.

2 / 3

Workflow Clarity

The patterns describe what to do but not in what order. There's no sequenced workflow for implementing the changes across the three files, and no validation/verification step to confirm the error envelopes are consistent across MCP and CLI.

Progressive Disclosure

For a skill under 50 lines with no need for external references, the content is well-organized into clear sections (Context, Patterns, Examples, Anti-Patterns) that are easy to scan and navigate.

Description

7%

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

This description is overly abstract and jargon-heavy, failing to communicate concrete actions or when the skill should be selected. It lacks a 'Use when...' clause and does not include natural trigger terms that users would employ. The technical specificity of 'MCP and CLI error envelopes' provides minimal distinctiveness but is insufficient to compensate for the other deficiencies.

Suggestions

Add a 'Use when...' clause specifying explicit triggers, e.g., 'Use when encountering MCP tool call errors, CLI command failures, or when error context is lost between retries.'

Replace abstract language with concrete actions, e.g., 'Captures and propagates error details, request IDs, and stack traces when MCP tool calls or CLI commands fail, enabling accurate retry and debugging.'

Include natural user-facing keywords such as 'error handling', 'debugging', 'retry', 'failed tool call', 'error message', and 'stack trace' to improve trigger term coverage.

DimensionReasoningScore

Specificity

The description uses abstract language like 'preserve service request context' and 'error envelopes' without listing any concrete actions. It does not specify what the skill actually does in practical terms.

1 / 3

Completeness

The description vaguely addresses 'what' (preserve context across error envelopes) but provides no 'when' clause or explicit trigger guidance. Both components are weak or missing.

1 / 3

Trigger Term Quality

The terms 'MCP', 'CLI error envelopes', and 'service request context' are highly technical jargon that users would rarely use naturally. Common user phrases like 'error handling', 'debugging', or 'retry' are absent.

1 / 3

Distinctiveness Conflict Risk

The mention of 'MCP and CLI error envelopes' provides some specificity that narrows the domain, but the overall vagueness of 'preserve service request context' could overlap with general error handling or logging skills.
