Manifest JSON Schema

The machine-readable contract for adapter manifests, served at a stable URL:

https://sabermage.github.io/spt-releases/manifest.schema.json

• Generated from the same code that parses manifests — the schema is always exactly what spt adapter add accepts structurally. It also ships as a release asset with every release.
• JSON Schema draft 2020-12; the $id is the canonical URL above and is stable across releases.
• Field doc-comments ride along as descriptions — the schema doubles as field-level documentation.
• Manifests are authored as TOML; the schema describes the equivalent data model (validate the TOML-parsed document).
• Cross-field rules the schema can’t express (kind↔[shell] agreement, strategy/avenue required fields) are listed in the manifest reference and enforced by spt adapter add.

Example — validate a manifest mechanically (Python, any JSON-Schema validator works the same way):

import json, tomllib, urllib.request, jsonschema

schema = json.load(urllib.request.urlopen(
    "https://sabermage.github.io/spt-releases/manifest.schema.json"))
with open("manifest.toml", "rb") as f:
    manifest = tomllib.load(f)
jsonschema.validate(manifest, schema)   # raises on violation
print("manifest is structurally valid")
