Cleaning Up Research Sessions

From the files and frontmatter at commit bfa0a6e. This is how much a skill can do, not whether it is risky.

• Runs shell commands

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

• Names web addresses

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

Pattern check: nothing flagged · commit bfa0a6e · 3 Nov 2026

We checked every text file in this skill, at commit bfa0a6e 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 "Cleaning Up Research Sessions" has uppercase letters and spaces. Names may use only a–z, 0–9 and single hyphens. N3

    Fix: Use name: cleaning-up-research-sessions.

  • Error

    The name "Cleaning Up Research Sessions" doesn't match its folder "cleaning-up-research-sessions". The spec requires them to match. N4

    Fix: Set name: cleaning-up-research-sessions, or rename the folder to cleaning-up-research-sessions.

  • Warning

    Fields outside the spec: when_to_use (read by Claude Code) and version. 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

    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.

• 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 name "Cleaning Up Research Sessions" doesn't match its folder "cleaning-up-research-sessions". Claude Code shows the skill as /Cleaning Up Research Sessions, and the folder name also invokes it. N4

    Fix: Set name: cleaning-up-research-sessions, or rename the folder to cleaning-up-research-sessions.

  • Note

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

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

• 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 "Cleaning Up Research Sessions" has uppercase letters and spaces. Anthropic's validator allows only lowercase letters, digits and hyphens. N3

    Fix: Use name: cleaning-up-research-sessions.

  • Error

    The name "Cleaning Up Research Sessions" doesn't match its folder "cleaning-up-research-sessions". claude.ai refuses an upload whose folder name doesn't match the skill name. N4

    Fix: Set name: cleaning-up-research-sessions, or rename the folder to cleaning-up-research-sessions.

  • Error

    Upload and packaging fail on fields outside the spec: when_to_use and version. O1

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

• 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 "Cleaning Up Research Sessions" has uppercase letters and spaces. OpenAI's upload follows the spec, which allows only a–z, 0–9 and hyphens. N3

    Fix: Use name: cleaning-up-research-sessions.

  • Warning

    The name "Cleaning Up Research Sessions" doesn't match its folder "cleaning-up-research-sessions". OpenAI's own upload example uses a differently named folder, but the spec it follows says they must match. N4

    Fix: Set name: cleaning-up-research-sessions, or rename the folder to cleaning-up-research-sessions.

  • Warning

    Fields outside the spec: when_to_use and version. 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.

• 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 "Cleaning Up Research Sessions" has uppercase letters and spaces. VS Code uses the folder name whenever the name differs from it. N3

    Fix: Use name: cleaning-up-research-sessions.

  • Warning

    The name "Cleaning Up Research Sessions" doesn't match its folder "cleaning-up-research-sessions". VS Code uses the folder name, cleaning-up-research-sessions, instead. N4

    Fix: Set name: cleaning-up-research-sessions, or rename the folder to cleaning-up-research-sessions.

  • Note

    VS Code ignores fields it doesn't support: when_to_use and version. O1

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