Codex marketplace catalog omits han-documentation, han-research, and han-linear

[ethan-hann]

What kind of feedback is this?

Bug

Which Han skill or agent does this involve?

Codex marketplace packaging for:

• han-documentation
• han-research
• han-linear

What happened, and what did you expect?

The README tells Codex users to install these packages directly, but two advertised commands fail:

codex plugin add han-documentation@han
codex plugin add han-research@han

Error: plugin `han-documentation` was not found in marketplace `han`
Error: plugin `han-research` was not found in marketplace `han`

Other Han packages install successfully from the same marketplace.

I expected every package advertised for Codex to appear in its marketplace catalog and include a valid Codex manifest.

Reproduction details

Environment:

• Windows
• Codex desktop and CLI
• Marketplace added from testdouble/han

han-documentation and han-research both have valid manifests:

han-documentation/.codex-plugin/plugin.json
han-research/.codex-plugin/plugin.json

However, neither package appears in:

.agents/plugins/marketplace.json

han-linear has a related problem. The README says it can be installed separately in Codex, but it:

• Is missing from .agents/plugins/marketplace.json.
• Has no han-linear/.codex-plugin/plugin.json.

No other package with an existing Codex manifest is missing from the catalog. The parent han package appears intentionally excluded because Codex does not support meta-plugins. see Codex issue 23531

Suggested fix

1. Add han-documentation and han-research to .agents/plugins/marketplace.json.
2. Add han-linear/.codex-plugin/plugin.json.
3. Add han-linear to .agents/plugins/marketplace.json.
4. Add a consistency test ensuring every package advertised for Codex has a manifest and catalog entry.

The affected installation instructions are in the Han README.
