| description | Install, configure, migrate, and validate a portable manifest registry for agent workflows, skills, subagents, and hooks. Use when a project needs manifest.yaml-based discovery, artifact versioning, dependency checks, capability declarations, permission-policy review, or reusable agent-platform setup. |
Manifest Platform
Install the bundled registry before creating or migrating manifests. In this repository, skills/manifest-platform is the canonical distributable package; runtime mirrors under .agents/skills or other profiles are generated from it.
bash skills/manifest-platform/scripts/install.sh --target .
For another project, copy this entire skills/manifest-platform/ folder into that project's skill source or profile skills_dir, then run the installer from the copied location. The installer infers a default runtime directory from where the skill lives: the shared Codex skill directory installs a Codex-style registry, while .codebuddy/skills and .agent/skills install under their matching runtime directories. Use --agent-dir and related directory options when the target project needs a layout different from the inferred default:
bash <skills-dir>/manifest-platform/scripts/install.sh --target /path/to/project --agent-dir .claude
bash <skills-dir>/manifest-platform/scripts/install.sh --target /path/to/project --agent-dir .agent --skills-dir .agent/skills
Read the manifest contract before defining a manifest, and read assets/platform/README.md before changing the registry layout or its commands.
Workflow
- Inspect the project layout and preserve unrelated changes.
- Install the registry. Review a differing existing registry before using
--force; never overwrite it by default.
- Review
<agent-dir>/platform/registry.yaml. Its defaults are generated from the installer options; change only the discovery paths or hook registration file that do not match the target project.
- Add
manifest.yaml for every artifact in a configured discovery directory. Keep metadata.name equal to its containing directory.
- Declare the narrowest truthful permissions. A manifest requests permissions; enforce them separately through the host runtime’s approval and tool policy.
- Add dependency IDs only after their target manifests exist. For a Hook, retain the actual registration in the JSON file declared by
policy.hooksConfig.
- Run
python3 <agent-dir>/platform/manifest-registry.py --root . validate and resolve every failure before handoff.
Reuse
Copy or sync this entire skill folder into another project's skill directory, then run its installer against that project. The installer supplies a dependency-free validator, JSON Schema, registry policy, and reference documentation, and it can generate registry paths for .codex, .claude, .agent, or a custom agent directory. Use manifest-registry.py init to create an initial manifest before refining its capabilities and permissions.
Do not treat the manifest as a sandbox. It is an auditable declaration, not a permission grant or a bypass of host policy.
