QAI Index
We rate every listed skill the same way, from 0 to 100.
A guide to compare by, not a verdict on the skill.
How we rateInstall
Each tab says whether it installs commit 1cf7835, the one we checked, or the latest version.
OpenCode also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.
Goose also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.
Windsurf (Devin Desktop) also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.
Zed also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.
Roo Code also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.
Factory Droid also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.
Junie also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.
Amp also looks in .agents/skills/ and ~/.agents/skills/, so use the Any agent steps.
No install command here reaches Kiro. Copy the skill's folder into .kiro/skills/ in your project, or ~/.kiro/skills/ for all your projects. garrytan/gstack/review (opens in a new tab)
Antigravity also looks in .agents/skills/, so the Any agent steps reach it with This project. For All projects, see where Antigravity looks.
Cline also looks in .claude/skills/, so the Claude Code steps reach it with This project. For All projects, see where Cline looks.

From the files and frontmatter at commit 1cf7835. This is how much a skill can do, not whether it is risky.
Pattern check
Pattern check: 1 item to review · commit 1cf7835 · 3 Nov 2026
We checked every text file in this skill, at commit 1cf7835 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.

- https://gstack.dev/schemas/section-manifest.json
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: preamble-tier, version, triggers and contract. 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
allowed-tools is a list; the spec defines a space-separated string. gh skill publish rejects a list, though Claude Code accepts one. O5
Fix: Write it on one line: allowed-tools: Bash Read Edit Write Grep Glob Agent AskUserQuestion WebSearch
- Warning
The body is 947 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 14,800 tokens (approx.); the spec suggests under 5,000. B2
Fix: Move detail into reference files that the agent reads only when needed.
- 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: TODOS-format.md, design-checklist.md, gate-integrity.md, specialists/api-contract.md, specialists/data-migration.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: checklist.md (259 lines), design-checklist.md (194 lines), gate-integrity.md (172 lines), greptile-triage.md (214 lines), sections/adversarial.md (295 lines) and 4 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
Claude Code ignores fields it doesn't know: preamble-tier, version, triggers and contract. O1
Fix: Check the spelling against Claude Code's field list, or delete them.
- Note
The body is 947 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 14,800 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: TODOS-format.md, design-checklist.md, gate-integrity.md, specialists/api-contract.md, specialists/data-migration.md and 8 more. Anthropic suggests linking every reference file directly from SKILL.md. B4

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: preamble-tier, version, triggers and contract. O1
Fix: Delete them, and keep your own data under metadata as text values.

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: preamble-tier, version, triggers and contract. 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
allowed-tools is a list; the spec defines a space-separated string. O5
Fix: Write it on one line: allowed-tools: Bash Read Edit Write Grep Glob Agent AskUserQuestion WebSearch
- 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: preamble-tier, version, triggers and contract. O1
Fix: Delete them unless another agent you target reads them.
- Note
allowed-tools is a list; the spec defines a space-separated string. O5
Fix: Write it on one line: allowed-tools: Bash Read Edit Write Grep Glob Agent AskUserQuestion WebSearch
