catalog_manifest_invalid:agents

Error message

catalog_manifest_invalid:agents

What it means

The sibling of the skills check: validateCatalogManifest requires 'agents' to be an array of agent entries. This error fires when agents is missing, an object, or a non-array value. An empty array is valid at this stage.

Solutions

  1. Set agents to an array ([] is acceptable if no agents exist)
  2. Regenerate the manifest with the official generator
  3. Validate the built manifest in CI

Example fix

// before
(no "agents" key)

// after
"agents": []
Defensive patterns

Strategy: validation

Validate before calling

if (!Array.isArray(raw.agents)) { raw.agents = raw.agents ?? []; /* or reject */ }

Type guard

function hasAgentsArray(v: unknown): v is { agents: unknown[] } { return typeof v === 'object' && v !== null && Array.isArray((v as any).agents); }

Prevention

When it happens

Trigger: A manifest where "agents" is absent or keyed as an object map rather than a list.

Common situations: Skill-only catalogs that omit the agents key entirely, or hand-edits converting lists to maps.

Understand the failure class

Background: Schema validation failed / invalid input schema: payload rejected because its shape doesn't match the expected schema — this error's family across 28 libraries.
