1Trust4 / 25 · 0.8/5

Evidence: The skill description only claims to briefly explain small code diffs; it does not involve permissions, data flow, sensitive data handling, or external effects. Although the repository is a full project, the skill itself has no additional permission requirements; its operation is limited to explaining diffs, with no overreach or hidden behavior. Deductions: The skill provides no user confirmation mechanism, data-flow transparency, or rollback options, and source attribution is not specified; however, no red-line risks are found, hence a basic score.

2Reliability2 / 20 · 0.5/5

Evidence: The skill file contains only a two-line descriptive text, with no concrete instructions or scripts; its runnability cannot be verified. Dependencies are not listed, key paths cannot be reproduced, and abnormal input handling is unspecified. Deductions: Lack of executable instructions, insufficient stability and failure feedback.

3Adaptability3 / 15 · 1.0/5

Evidence: The skill's scope is clear (explain small code diffs) and the audience is developers, but it does not declare capability boundaries or non-fit scenarios; trigger conditions rely solely on the description. Chinese-language support is not mentioned, and the project may depend on overseas services; environment fit is unverified. Deductions: Boundaries and trigger conditions are unclear, and evidence for environment fit is insufficient.

4Convention4 / 15 · 1.3/5

Evidence: The skill has a brief description and name, but no installation instructions, examples, FAQ, known limitations, versioning, or maintenance responsibility. The repository has an Apache-2.0 license, but the skill itself does not specify license attribution. Deductions: Incomplete information architecture, missing key documentation and governance.

5Effectiveness1 / 15 · 0.3/5

Evidence: The skill claims to explain diffs but provides no concrete output format or verified examples; result correctness and completeness cannot be assessed. Manually explaining a diff may be more direct; marginal value is unproven. Deductions: Unclear value proposition, output not verifiable.

6Verifiability0 / 10 · 0.0/5

Evidence: The skill file contains no tests or verifiable execution evidence; the repository has CI and tests but they do not cover this skill. Deductions: No third-party execution evidence; static reading cannot verify conclusions.

The upstream repository has new commits since this review. The score still applies to the reviewed revision shown and may not cover the latest changes.
Before you use it
  • The skill description is extremely brief, with only declarative text and no executable instructions; actual usage requires supplementing implementation logic.
  • No declaration of suitability for Chinese-language environments or reachability from mainland China; if it depends on overseas LLM services, it may be inaccessible.
  • Lack of tests, examples, and error handling descriptions; reliability is hard to guarantee.

What does this skill do, and when should you use it?

This is a minimal Agent Skill designed to briefly explain small code diffs. It takes a diff as input and outputs a short natural language explanation of the changes. The skill is intentionally simple, emphasizing brevity. It is part of the Cognee repository as a demo for feedback loops. It follows the standard Agent Skills format and is easy to integrate.

Accepts a code diff as input and generates a concise text explanation of the changes. It does not execute tests, call external APIs, or access the filesystem. Its only function is to produce a natural language summary from the given diff.

  1. A developer reviewing a pull request wants a quick summary of a small change.
  2. A developer browsing Git history wants to understand what a commit changed.
  3. A developer debugging wants to grasp the impact of a local modification.

What are this skill's strengths and limitations?

Pros
  • Simple and straightforward.
  • Good for quick understanding of small changes.
  • No extra tools or services required.
Limitations
  • Too simple for complex analyses.
  • Lacks detailed installation instructions.
  • No mention of supported platforms or languages, may have compatibility issues.

How do you install this skill?

Clone the GitHub repository, then copy the folder 'examples/demos/skill_feedback_loop/skills/diff-risk-explainer' into your Agent Skills directory. Detailed installation steps are not documented.

How do you use this skill?

Present a code diff to the Agent and ask 'Explain this diff'.

FAQ

Does this skill require an LLM API key?
The SKILL.md does not mention any API key, but such skills typically rely on the agent's underlying model. Refer to the repository docs for details.
Can it handle large diffs?
The SKILL.md explicitly says 'small code diffs', so large diffs may produce overly long or inaccurate summaries.
How do I add this skill to my agent?
Copy the skill folder into your Agent Skills directory; the exact path depends on your agent platform.
