impeccable
impeccable is a skill in pbakaus/impeccable, last changed 2 Nov 2026. It can run shell commands, reach the network, name web addresses and bundle scripts — read the findings before installing.
Use when the user wants to design, redesign, shape, critique, audit, polish, simplify, harden, animate, or otherwise improve a frontend interface: websites, landing pages, dashboards, product UI, components, forms, settings, onboarding, empty states, and native iOS or Android screens. Handles UX review, hierarchy, layout, typography, color, motion, UX copy, accessibility, responsive behavior, edge cases, and capturing or documenting design systems (DESIGN.md, tokens). Also for making bland UI bolder, loud UI quieter, or ambitious visual effects. Not for backend-only or non-UI tasks.

Pattern check
Pattern check: 2 items to review · commit 9fadc41 · 3 Nov 2026
We checked every text file in this skill, at commit 9fadc41 on 3 Nov 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.

Format check
Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.
Agent Skills specPasses with warnings
The open format from agentskills.io, held to the strictest version of each rule among the agents we check.
- Warning
Fields outside the spec: version, user-invocable (read by Claude Code and VS Code) and argument-hint (read by Claude Code and VS Code). Uploads to the Claude apps and API, and the spec's validator, reject the file; most agents ignore these fields. O1
Fix: Delete them for a portable skill, or keep them if you only target the agents that read them.
- Note
The first sentence of the description is 285 characters. Agents shorten long descriptions, so lead with the main job. D8
Fix: Start with one short sentence that names the job.
- Note
Reference files that SKILL.md doesn't link: reference/android.md (linked only from reference/adapt.native.md), reference/component-review.md (linked only from reference/degraded/asset-producer.md), reference/degraded/asset-producer.md, reference/degraded/documenter.md (linked only from reference/new-work.md), reference/degraded/finish-reviewer.md (linked only from reference/new-work.md) and 8 more. Anthropic suggests linking every reference file directly from SKILL.md. B4
Fix: Link each one from SKILL.md and say when to read it.
- Note
Reference files over 100 lines with no table of contents at the top: reference/adapt.md (319 lines), reference/audit.md (140 lines), reference/audit.native.md (140 lines), reference/critique.md (820 lines), reference/distill.md (112 lines) and 12 more. B5
Fix: Add a short list of the sections at the top of each.
- Warning
Claude CodePasses
Claude Code reads its own extra fields, ignores unknown ones, and still loads a skill whose frontmatter is broken, without its fields.
- Note
The first sentence of the description is 285 characters. Agents shorten long descriptions, so lead with the main job. D8
Fix: Start with one short sentence that names the job.
- Note
Claude Code ignores fields it doesn't know: version. O1
Fix: Check the spelling against Claude Code's field list, or delete them.
- Note
Reference files that SKILL.md doesn't link: reference/android.md (linked only from reference/adapt.native.md), reference/component-review.md (linked only from reference/degraded/asset-producer.md), reference/degraded/asset-producer.md, reference/degraded/documenter.md (linked only from reference/new-work.md), reference/degraded/finish-reviewer.md (linked only from reference/new-work.md) and 8 more. Anthropic suggests linking every reference file directly from SKILL.md. B4
Fix: Link each one from SKILL.md and say when to read it.
- Note
Reference files over 100 lines with no table of contents at the top: reference/adapt.md (319 lines), reference/audit.md (140 lines), reference/audit.native.md (140 lines), reference/critique.md (820 lines), reference/distill.md (112 lines) and 12 more. B5
Fix: Add a short list of the sections at the top of each.
- Note
Claude apps & API uploadFails
Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.
- Error
Upload and packaging fail on fields outside the spec: version, user-invocable and argument-hint. O1
Fix: Delete them, and keep your own data under metadata as text values.
- Note
The description is 589 characters. The claude.ai Help Center says 200 at most, though Anthropic's API docs and validator allow 1,024. D4
Fix: If the claude.ai upload refuses it, trim the description to 200 characters.
- Note
Reference files that SKILL.md doesn't link: reference/android.md (linked only from reference/adapt.native.md), reference/component-review.md (linked only from reference/degraded/asset-producer.md), reference/degraded/asset-producer.md, reference/degraded/documenter.md (linked only from reference/new-work.md), reference/degraded/finish-reviewer.md (linked only from reference/new-work.md) and 8 more. Anthropic suggests linking every reference file directly from SKILL.md. B4
Fix: Link each one from SKILL.md and say when to read it.
- Note
Reference files over 100 lines with no table of contents at the top: reference/adapt.md (319 lines), reference/audit.md (140 lines), reference/audit.native.md (140 lines), reference/critique.md (820 lines), reference/distill.md (112 lines) and 12 more. B5
Fix: Add a short list of the sections at the top of each.
- Error
OpenAI (Codex & API)Passes with warnings
Codex finds SKILL.md by its exact name and needs a description; OpenAI's Skills API checks the frontmatter against the spec and caps uploads.
- Warning
Fields outside the spec: version, user-invocable and argument-hint. Codex ignores them; OpenAI doesn't say whether its upload accepts them. O1
Fix: Delete them, or move your own data under metadata as text values.
- Note
The first sentence of the description is 285 characters. Agents shorten long descriptions, so lead with the main job. D8
Fix: Start with one short sentence that names the job.
- Warning
VS Code & CopilotPasses
VS Code reads skills one folder below .github/skills, .claude/skills or .agents/skills and falls back to the folder name when the name is missing or differs; GitHub's Copilot docs require the exact name SKILL.md.
- Note
VS Code ignores fields it doesn't support: version. O1
Fix: Delete them unless another agent you target reads them.
- Note
SKILL.md
