Compatibility Matrix
Status vocabulary
| Status | Meaning |
|---|---|
| Officially supported | Provider documents the format/capability as supported. |
| Supported through shared standard | Provider documents compatibility with the open standard. |
| Generated adapter | Intentloom can emit a documented provider-native format. |
| Experimental | Provider behavior or Intentloom mapping is preview/unstable; requires opt-in. |
| Unsupported | Intentloom deliberately does not generate or rely on it. |
v0.1 implemented assessment
| Capability | Claude Code | OpenAI Codex | Cursor | GitHub Copilot |
|---|---|---|---|---|
| Repository instructions | Officially supported (CLAUDE.md) | Officially supported (AGENTS.md) | Officially supported (AGENTS.md, Rules) | Officially supported (instructions and AGENTS.md) |
Shared AGENTS.md | Via CLAUDE.md import | Officially supported | Officially supported | Officially supported |
| Agent Skills | Officially supported | Officially supported | Supported through shared standard | Officially supported |
| Path-scoped rules | Officially supported | Adapter-dependent; not canonical | Officially supported | Officially supported |
| Custom subagents | Officially supported | Experimental / adapter discovery required | Experimental / adapter discovery required | Officially supported |
| Intentloom native adapter | Generated adapter | Generated adapter | Generated adapter | Generated adapter |
All four adapter rows are implemented and covered by real-catalog, conflict, drift, stale-version, removal, idempotence, multi-adapter, snapshot, and packed CLI fixtures. Cursor Agent Skills and Copilot custom-agent capability remain experimental; Intentloom does not fabricate Copilot custom-agent output.
Runtime and host matrix
| Runtime/host | Status |
|---|---|
| Node 22 | Supported minimum; complete local suite and packed CLI verified |
| Node 24 | Supported; complete CI matrix verified |
| Linux | Hosted compatibility CI verified on Node 22 and 24 |
| macOS | Hosted compatibility CI verified on Node 22 and 24 |
| Windows | Hosted compatibility CI verified on Node 22 and 24; no local execution is claimed |
The cross-platform verdict is resolved for the hosted Node 22/24 matrix. See Compatibility run 29374780862 for the recorded host evidence.
Source basis
- Claude Code documents
CLAUDE.mdimports, including importingAGENTS.md, in How Claude remembers your project; skills and subagents are documented in Agent Skills and subagents. - Codex uses repository
AGENTS.mdguidance and Agent Skills; Intentloom will re-verify exact target behavior at implementation time against OpenAI Codex documentation. - Cursor documents project Rules and root
AGENTS.mdin Rules. - Copilot documents repository instructions, path instructions, and
AGENTS.mdsupport in repository custom instructions, and skills in About agent skills. - Portable skill structure is defined by the Agent Skills specification;
AGENTS.mdis intentionally plain Markdown per agents.md.
Policy
Provider behavior is never inferred from another provider or community convention. Intentloom records the source, tested provider version/range, adapter version, and fixture result before changing a compatibility status. Undocumented formats and private/internal APIs are unsupported.
