# Plugin manifest

> Every field of quivr-plugin.yaml, generated from its JSON Schema.

Every field of `quivr-plugin.yaml`, the manifest a plugin ships. It is written in YAML and validated as the equivalent JSON value against `plugin-manifest.schema.json`; `quivr plugin inspect` checks it the way the engine does. Unknown fields are rejected.

| `contributions.connector.kinds.<name>.modes` | array of `pull`, `push` | no | pull: the core schedules fetch. push, since Plugin API 0.5: the core relays the deliveries a source sends to the instance's public webhook route to receive, and returns the plugin's answer to the source.

| `contributions.connector.attachments` | object | no | Since Plugin API 0.4: items may carry attachments. The core asks for each attachment's size and SHA-256 (describe\_attachment), issues an upload grant and has the plugin upload the bytes against it (upload\_attachment). Without this block a page with attachments is refused. |
| `contributions.connector.attachments.max_bytes` | integer | no | Largest attachment the plugin uploads; it can only lower the engine's 25 MiB cap. 1 to 26214400. Default `26214400`. |
| `contributions.connector.attachments.timeout_ms` | integer | no | Deadline of one describe\_attachment or upload\_attachment invocation. 1000 to 120000. Default `120000`. |

| - | - | - | - |
| `contributions.ingestion` | object | no | Segmentation and embedding, since Plugin API 0.6: cut one Record Version's text Parts into segments and embed each segment in the vector spaces the plugin owns (segment\_and\_embed), and encode a query into one of those spaces (embed\_query). The core keeps the index, the registry of spaces, authorization, withdrawal and projection generations. |
| `contributions.ingestion.spaces` | map of object | yes | The vector spaces this plugin owns, by space id. A deployment enables some of them: one served, the others for evaluation. 1 to 8 entries. |

| `contributions.ingestion.spaces.<name>.description` | string | no | 1 to 1024 characters. |
| `contributions.ingestion.timeout_ms` | integer | no | Deadline of one segment\_and\_embed invocation. 1000 to 300000. Default `30000`. |
| `contributions.ingestion.query_timeout_ms` | integer | no | Deadline of one embed\_query invocation; a search waits for it. 100 to 10000. Default `2000`. |

## Retrieval

| Field | Type | Required | Description |
| - | - | - | - |
| `contributions.retrieval` | object | no | Search, since Plugin API 0.7: answer one search in rounds. Each round the plugin either asks the core for candidates (keyword, vector on a named space, hybrid) or returns the final ranking, chosen only among candidates the core served in this search. The core keeps the index, encodes queries with each space's owner, and applies authorization, withdrawal and generation routing before serving any candidate. |
| `contributions.retrieval.profiles` | map of object | yes | The search profiles this plugin answers, by name; default is required and answers a search that names no profile. 1 to 8 entries. |
| `contributions.retrieval.profiles.<name>.description` | string | no | 1 to 1024 characters. |
| `contributions.retrieval.profiles.<name>.max_latency_ms` | integer | yes | Deadline of one whole search under this profile, every round and every candidate request included. The core stops a search that runs longer and answers search\_deadline\_exceeded. 50 to 10000. |
| `contributions.retrieval.profiles.<name>.max_cost_cents` | number | yes | Most paid spend one search may report in usage.cost\_cents (for example a re-ranking or rewriting API); 0 for a profile without paid calls. 0 to 100. |
