slack-gif-creator Eval report.

Validation plan

What the agent should do next

1. 1Inspect repository, README/SKILL.md, license, and recent commits before production use.
2. 2Install in an isolated workspace or sandbox with no production secrets available.
3. 3Run the smallest representative task and record files touched, commands run, network access, and outputs.
4. 4Compare the selected skill against at least one alternative when the eval status is review or failed.
5. 5Promote only after the agent reports a successful verification result and unresolved warnings are accepted.

Do not use when

Conditions that require another skill

• teams that need a vendor-supported SLA
• production agents without a repository review
• SKILL.md does not include an explicit Setup section listing required dependencies (Pillow, numpy, imageio) or installation instructions.
• High-risk permission hints: Shell or command execution
• The skill accepts user-uploaded images and opens them with PIL, but SKILL.md does not warn about decompression bombs, image size limits, or safe file validation before processing.
• No limitations section describes what the skill cannot do, such as rendering emoji fonts reliably, handling video inputs, or producing very large/high-FPS GIFs beyond Slack constraints.
