research/discover-topics

Topic Discovery workflow — find trending topics for a niche.

Category: research
Source: workflows/research/discover_topics.py

Input Schema

Field	Type	Default	Description
`min_score`	`integer`	`5`	Minimum virality score to include
`niche`	`string`	`""`	Content niche (e.g. ‘AI tools’, ‘fitness’, ‘cooking’)
`num_topics`	`integer`	`10`	Number of topics to return
`regenerate`	`object`	—	When set, this run is a regeneration. Workflows may read `direction` / `keep` / `extra_instructions` to modulate prompts; the engine persists `parent_run_id` and `parent_variant_index` as run lineage columns.
`variants`	`integer`	`1`	Number of independent variant executions (1–10). When > 1, the engine runs the workflow N times with different sampling, producing N outputs.

Output Schema

Field	Type	Default	Description
`best_topic`	`object`	—	Highest-scoring topic
`discovery_context`	`string`	`""`	Formatted research context for downstream generation
`kind`	`object`	—	Variant card shape: video / carousel / image / text. Surfaced on the per-variant entry of the run-output API and used by gallery UIs to pick the right layout.
`topics`	`object[]`	—	Discovered topics with virality scores
`workflow`	`string`	`"discover-topics"`	Workflow identifier

discover_topics

Task	Description
`discover_topics`	Discover trending topics — delegates to SDK stage.

Run-spec example

Save the YAML below as my-run.yaml, edit the values, and run with the CLI or POST it to the API. Required fields are uncommented; optional knobs are documented above the input: block — copy any line under input: and uncomment to set.

workflow: research/discover-topics

# Optional fields — copy any line(s) under `input:` and uncomment to set:
# Minimum virality score to include
#   min_score: 5
#
# Content niche (e.g. 'AI tools', 'fitness', 'cooking')
#   niche: ""
#
# Number of topics to return
#   num_topics: 10
#

input: {}

Run it locally:

fab-workflow --from-file my-run.yaml

Or submit over the wire — the same file is the request body:

curl -X POST 'https://gofabric.dev/v1/workflows/runs?name=research/discover-topics' \
  -H 'Authorization: Bearer fab_xxx' \
  -H 'content-type: application/yaml' \
  --data-binary @my-run.yaml

Every workflow also accepts the universal WorkflowInput fields — variants (1–10 fan-out) and regenerate (creative-direction hints with run lineage). See Run-specs (YAML / TOML / JSON) for the full top-level shape (metadata, priority, bundle, parent, etc.).

Warnings

Task discover_topics has no Pydantic types — contract is opaque to consumers.
