Experimental Claw packages

ClawHub's Claw support implements the registry side of the merged OpenClaw RFC 0016, the experimental portable-core addendum in RFC #48, and the application-layer follow-up in RFC #52. A Claw package describes one complete new agent using the grouped CLAW.md schema. ClawHub owns publication, ownership, discovery, package detail APIs, and hosted feed export. OpenClaw remains authoritative for local planning, consent, mutation, provenance, update, and removal.

The YAML frontmatter is the portable manifest. A CLAW.md package envelope may be frontmatter-only. When its body contains non-whitespace text, the exact body text is the implicit managed SOUL.md workspace file; an empty or whitespace-only body creates no implicit file. The manifest must not declare a workspace destination that equals, contains, or is contained by that implicit SOUL.md path. The exact CLAW.md bytes, including the body, remain in the immutable artifact digest and provenance input. Grouped JSON has no body, creates no implicit file, and may declare SOUL.md explicitly.

The portable agent object carries only identity and purpose. Harness-specific settings live in package-local profiles discovered at conventional profiles/<harness>.yml paths; the manifest contains no profile pointer. metadata.openclaw.config is retired and rejected with migration guidance.

Profiles exist only inside the Claw package. ClawHub reserves the profiles/ namespace for lowercase, single-file harness profiles, requires each profile to be a bounded UTF-8 JSON-compatible YAML mapping, and rejects aliases, anchors, tags, merge keys, non-string mapping keys, and non-finite values. It validates the strict profile-v1 structure of profiles/openclaw.yml without resolving built-in profile names, installing extensions, or claiming compatibility with a particular applying OpenClaw release. Foreign profiles remain structurally validated but uninterpreted. Applying harnesses discover only their own profile.

ClawHub validates profile shape but treats agent.tools.profile as an opaque, non-empty applying-harness identifier. It does not freeze OpenClaw's evolving built-in profile registry; OpenClaw resolves the identifier against its current registry during preview and application.

An optional package-root BOOTSTRAP.md carries reviewed first-run instructions. It must be bounded, nonempty UTF-8 text and cannot also be targeted through the portable workspace file map. Its presence is included in the bounded manifest summary, while its contents remain only in the exact immutable artifact. Schemas, templates, examples, fixtures, and static assets require no special registry role: they remain ordinary declared workspace.files covered by the artifact digest.

Experimental contract

• Backend Claw publication and read surfaces require CLAWHUB_EXPERIMENTAL_CLAWS=1.
• The gate is not user consent and must not bypass validation, moderation, ownership, or scanner checks.
• Disabled deployments must not accept Claw publication or expose Claws through Claw-specific discovery surfaces.
• Public Claw schemas and APIs may change while the gate is required. Removing the gate requires a separate compatibility and migration decision.

Staged implementation

1. Add the shared grouped manifest contract, safe summary, and storage model (PR #3089).
2. Add feature-gated authenticated publication, package-content validation, CLI authoring support, and authoring docs (PR #3090).
3. Add feature-gated search, detail, and API surfaces (PR #3091).
4. Add a separately gated hosted Claws feed and a repeatable published-package proof through OpenClaw claws add --dry-run (PR #3092).
5. Validate the portable CLAW.md prompt body, project it as managed SOUL.md capability metadata, and prove the feed-to-OpenClaw mapping (PR #3262, stacked after PR #3092).
6. Adopt conventional harness profiles, package-root bootstrap, native OpenClaw extensions, and ordinary application assets (PR #3328).

The hosted projection uses the separate experimental Claw feed contract, not an extension of the stable plugin/skill catalog feed v1 schema.

The shared validator follows the RFC's strict v1 contract: strings are not trimmed into validity, MCP package selectors must resolve exact versions, process environment keys follow OpenClaw's host-wide safety policy, and tool filters accept only exact names plus * wildcards. Registry validation must not accept a declaration that the applying OpenClaw client rejects.

OPENCLAW_CLAW_HOST_ENV_POLICY_V1 is the versioned cross-repository compatibility artifact for that environment policy. It records the exact OpenClaw source path, consumer commit, and source-file SHA-256; ClawHub derives its blocked-key lookups from the artifact and runs every key/prefix as a conformance vector. A policy change requires a new reviewed artifact version or an intentional update of the existing experimental v1 contract.

Manifest rejections expose stable claw_v1_* diagnostic codes with phase schema, plus the field path and human-readable message. Consumers may branch on the code and phase; messages are explanatory text rather than identifiers.

The durable version document stores only the bounded manifest summary. Its field structure is built from createClawManifestSummarySchema in both the public ArkType contract and the Convex storage validator. Convex cannot express the summary text-length caps, so publication must validate or derive summaries through the shared schema before storage.

Claws use the existing package publication pipeline. package.json declares the package identity, version, and package-relative openclaw.claw manifest path. Publication parses CLAW.md YAML frontmatter or the JSON compatibility form and validates the grouped manifest, referenced workspace files, conventional harness profiles, and optional package-root bootstrap. A non-empty Markdown body is the portable agent prompt and maps to managed SOUL.md; publication rejects a body combined with any explicit SOUL.md workspace declaration. The release retains the exact artifact and a bounded derived summary, including implicit prompt and bootstrap presence, rather than duplicating the full manifest, prompt body, profile, or bootstrap content into Convex storage. The server rejects family: claw before mutation when the experimental gate is disabled; the gate does not bypass ownership, moderation, scanning, or release invariants when enabled.
