Reference
Supported tools
Which AI coding tools OpenSpec supports, and each one's command syntax.
Every tool in the matrix runs the same OpenSpec workflows. A skill and its command are the same workflow instructions. The only difference is what you type. Which form init installs is the delivery setting, covered in Set up your project.
Support matrix
Invocations are shown for the apply workflow. Every workflow follows the same shape.
The id goes to openspec init --tools <id> to skip the picker (CLI).

- Skill invocation: whether a tool registers skills as typed entries is the tool's own behavior. The column shows the spelling OpenSpec uses in generated files and in the hint init prints. Check your tool's docs if typing it does nothing.
- Command file formats: most tools take
.mdcommand files. Gemini CLI takes.toml, Continue.prompt, Kiro and GitHub Copilot.prompt.md. The spelling you type is the same either way.
Per-tool notes
A tool not listed here behaves exactly as its row reads.
Antigravity
- Current folder: Antigravity v1.20.5 and later read workspace skills and
workflows from
.agents/. - Legacy folder: after OpenSpec writes replacements, it removes equivalent
generated files from
.agent/. Custom files and changed generated files stay in.agent/for you to review. - Shared skills: Antigravity shares
.agents/skills/with Codex, Zed Agent, and theagentstarget. OpenSpec writes that skill tree once while still writing Antigravity commands to.agents/workflows/.
Cline
Cline reads commands from .clinerules/workflows/, not from its .cline/ folder.
Skills stay in .cline/skills/.
Codex
- Invocation: type
$openspec-<skill>. Codex does not recognize the/openspec-<skill>form (upstream issue). - No command files: Codex runs skills directly, so init skips commands even when
delivery includes them and prints
Commands skipped for: codex (uses skills). - Shared folder: Codex skills land in
.agents/skills/, the same tree Antigravity, Zed Agent, and theagentstarget use. Selecting more than one keeps a single compatible tree, and its handoffs spell both$openspec-*and/openspec-*when Codex owns it. - Legacy path: skills installed under
.codex/skills/by older versions are migrated on the nextopenspec update.
Devin Desktop (formerly Windsurf)
- Two agents: command files in
.devin/workflows/work only in Devin Desktop. Devin Local runs skills only, so generated skills reference/openspec-<skill>, which works in both. - Rename:
--tools windsurfstill resolves todevin. A project holding OpenSpec files in the legacy.windsurf/folder is offered the move on the nextopenspec update.
GitHub Copilot
Prompt files register as slash commands in the Copilot IDE extensions (VS Code,
JetBrains, Visual Studio). Copilot CLI does not read .github/prompts/.
Hermes Agent
Hermes loads skills only from ~/.hermes/skills/ by default. Add the project's
.hermes/skills/ folder to skills.external_dirs in ~/.hermes/config.yaml;
init prints this reminder after install.
MiniMax Code
- Global only: skills go to
~/.minimax/skills/. Nothing is written inside the repo. - Safe across projects: a commands-only delivery leaves the global skills in place, so one project's setting cannot remove skills another project uses.
Shared .agents skills
- When it fits: any tool that reads the shared
.agents/skills/folder, including tools with no row in the matrix. - Alongside other targets: Antigravity, Codex, Zed Agent, and this target share
one physical skill tree. OpenSpec records one writer in
.openspec-targetand writes the tree once per run. Each tool's separate command files are still generated. - What OpenSpec claims: only the
openspec-*folders and the.openspec-targetmarker. Anything else under.agents/is left alone. AGENTS.md: not created or edited. The target is the.agents/folder, not the file.
