video-sdk/web

From the files and frontmatter at commit 2574e29. This is how much a skill can do, not whether it is risky.

• Downloads software

  It fetches programs or packages from the internet, or from a package source other than the default.

  examples/react-hooks.md:9 (opens in a new tab)

• Runs shell commands

  Its instructions or files give the agent commands to run on your computer.

• Reaches the network

  It sends or fetches data over the internet, for example with curl, an HTTP library or a package install.

• Names web addresses

  It mentions outside web addresses the agent may visit. We list them but don't follow them.

  Outside links we did not follow

Pattern check: nothing flagged · commit 2574e29 · 3 Nov 2026

We checked every text file in this skill, at commit 2574e29 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.

How the check worksReport an incorrect finding

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 specFails

  The open format from agentskills.io, held to the strictest version of each rule among the agents we check.

  • Error

    The name "video-sdk/web" doesn't match its folder "web". The spec requires them to match. N4

    Fix: Set name: web, or rename the folder to video-sdk-web.

  • Error

    The name "video-sdk/web" contains "/", which reads as a namespace prefix (video-sdk). Only a–z, 0–9 and hyphens are allowed. N7

    Fix: Drop the prefix: name: web. Plugins add their own prefix.

  • Warning

    Fields outside the spec: user-invocable (read by Claude Code and VS Code) and triggers. 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.

  • Warning

    The body is 809 lines; the spec suggests under 500. B1

    Fix: Move detailed sections into reference files and link to them from SKILL.md.

  • Warning

    The body is about 6,457 tokens (approx.); the spec suggests under 5,000. B2

    Fix: Move detail into reference files that the agent reads only when needed.

  • Warning

    Paths that may not work once the skill is installed: line 19: ../../meeting-sdk/web/component-view/SKILL.md (outside the skill folder), line 38: ../../probe-sdk/SKILL.md (outside the skill folder), line 87: ../../probe-sdk/SKILL.md (outside the skill folder) and line 91: ../../general/use-cases/probe-sdk-preflight-readiness-gate.md (outside the skill folder). B6

    Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.

  • Note

    The description doesn't say when to use the skill. D6

    Fix: Add a sentence such as "Use when …" naming the requests or files that should trigger it.

  • Note

    There is no license field, so readers can't tell whether they may reuse the skill. O2

    Fix: Add license: with an SPDX name such as MIT or Apache-2.0, or the name of a bundled licence file.

  • Note

    Reference files that SKILL.md doesn't link: references/web.md. 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: concepts/sdk-architecture-pattern.md (324 lines), concepts/singleton-hierarchy.md (406 lines), examples/chat.md (492 lines), examples/command-channel.md (227 lines), examples/event-handling.md (533 lines) and 11 more. B5

    Fix: Add a short list of the sections at the top of each.

• Claude CodePasses with warnings

  Claude Code reads its own extra fields, ignores unknown ones, and still loads a skill whose frontmatter is broken, without its fields.

  • Warning

    Paths that may not work once the skill is installed: line 19: ../../meeting-sdk/web/component-view/SKILL.md (outside the skill folder), line 38: ../../probe-sdk/SKILL.md (outside the skill folder), line 87: ../../probe-sdk/SKILL.md (outside the skill folder) and line 91: ../../general/use-cases/probe-sdk-preflight-readiness-gate.md (outside the skill folder). B6

    Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.

  • Note

    The name "video-sdk/web" doesn't match its folder "web". Claude Code shows the skill as /video-sdk/web, and the folder name also invokes it. N4

    Fix: Set name: web, or rename the folder to video-sdk-web.

  • Note

    Claude Code ignores fields it doesn't know: triggers. O1

    Fix: Check the spelling against Claude Code's field list, or delete them.

  • Note

    The body is 809 lines; the spec suggests under 500. Claude Code's docs say the same. B1

    Fix: Move detailed sections into reference files and link to them from SKILL.md.

  • Note

    The body is about 6,457 tokens (approx.); the spec suggests under 5,000. After compaction Claude Code keeps only the first 5,000 tokens of a skill. B2

    Fix: Move detail into reference files that the agent reads only when needed.

  • Note

    Reference files that SKILL.md doesn't link: references/web.md. 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: concepts/sdk-architecture-pattern.md (324 lines), concepts/singleton-hierarchy.md (406 lines), examples/chat.md (492 lines), examples/command-channel.md (227 lines), examples/event-handling.md (533 lines) and 11 more. B5

    Fix: Add a short list of the sections at the top of each.

• 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

    The name "video-sdk/web" doesn't match its folder "web". claude.ai refuses an upload whose folder name doesn't match the skill name. N4

    Fix: Set name: web, or rename the folder to video-sdk-web.

  • Error

    The name "video-sdk/web" contains "/", which reads as a namespace prefix (video-sdk). Only a–z, 0–9 and hyphens are allowed. N7

    Fix: Drop the prefix: name: web. Plugins add their own prefix.

  • Error

    Upload and packaging fail on fields outside the spec: user-invocable and triggers. O1

    Fix: Delete them, and keep your own data under metadata as text values.

  • Warning

    Paths that may not work once the skill is installed: line 19: ../../meeting-sdk/web/component-view/SKILL.md (outside the skill folder), line 38: ../../probe-sdk/SKILL.md (outside the skill folder), line 87: ../../probe-sdk/SKILL.md (outside the skill folder) and line 91: ../../general/use-cases/probe-sdk-preflight-readiness-gate.md (outside the skill folder). B6

    Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.

  • Note

    The body is 809 lines; the spec suggests under 500. Anthropic's guidance says the same. B1

    Fix: Move detailed sections into reference files and link to them from SKILL.md.

  • Note

    The body is about 6,457 tokens (approx.); the spec suggests under 5,000. Anthropic's guidance says the same. B2

    Fix: Move detail into reference files that the agent reads only when needed.

  • Note

    Reference files that SKILL.md doesn't link: references/web.md. 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: concepts/sdk-architecture-pattern.md (324 lines), concepts/singleton-hierarchy.md (406 lines), examples/chat.md (492 lines), examples/command-channel.md (227 lines), examples/event-handling.md (533 lines) and 11 more. B5

    Fix: Add a short list of the sections at the top of each.

• OpenAI (Codex & API)Fails

  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.

  • Error

    The name "video-sdk/web" contains "/", which reads as a namespace prefix (video-sdk). Only a–z, 0–9 and hyphens are allowed. N7

    Fix: Drop the prefix: name: web. Plugins add their own prefix.

  • Warning

    The name "video-sdk/web" doesn't match its folder "web". OpenAI's own upload example uses a differently named folder, but the spec it follows says they must match. N4

    Fix: Set name: web, or rename the folder to video-sdk-web.

  • Warning

    Fields outside the spec: user-invocable and triggers. 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.

  • Warning

    Paths that may not work once the skill is installed: line 19: ../../meeting-sdk/web/component-view/SKILL.md (outside the skill folder), line 38: ../../probe-sdk/SKILL.md (outside the skill folder), line 87: ../../probe-sdk/SKILL.md (outside the skill folder) and line 91: ../../general/use-cases/probe-sdk-preflight-readiness-gate.md (outside the skill folder). B6

    Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.

• VS Code & CopilotPasses with warnings

  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.

  • Warning

    The name "video-sdk/web" doesn't match its folder "web". VS Code uses the folder name, web, instead. N4

    Fix: Set name: web, or rename the folder to video-sdk-web.

  • Warning

    The name "video-sdk/web" contains "/", which reads as a namespace prefix (video-sdk). VS Code's docs say such a name fails to load; VS Code falls back to the folder name. N7

    Fix: Drop the prefix: name: web. Plugins add their own prefix.

  • Warning

    Paths that may not work once the skill is installed: line 19: ../../meeting-sdk/web/component-view/SKILL.md (outside the skill folder), line 38: ../../probe-sdk/SKILL.md (outside the skill folder), line 87: ../../probe-sdk/SKILL.md (outside the skill folder) and line 91: ../../general/use-cases/probe-sdk-preflight-readiness-gate.md (outside the skill folder). B6

    Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.

  • Note

    VS Code ignores fields it doesn't support: triggers. O1

    Fix: Delete them unless another agent you target reads them.
