Tools (54)

• agreements_create
  Upsert an agreement for (run, response, metric, created_by). Verdict is one of agree, disagree, borderline. corrected_score (1..5) is required when verdict is 'disagree'.
• agreements_list
  List agreements. Filter by run_id, response_id, metric_id, or created_by.
• datasets_create
  Create a dataset with CSV data. First row is the header. Two column names are recognized specially: "expected_output" is each row's answer key (ground truth) given to the judge and to checks that com…
• datasets_create_from_url
  Create a dataset by downloading CSV from a URL instead of inlining it. Use this for large datasets: pass a public http(s) URL and the server fetches the CSV directly, so the data never has to pass th…
• datasets_delete
  Delete a dataset
• datasets_get
  Get a dataset by ID
• datasets_list
  List all datasets
• datasets_update
  Update a dataset
• judges_compare
  Compare two versions of one metric's agreement stats side by side. Requires metric_id, metric_version_a_id, and metric_version_b_id (both versions must belong to that metric). Unavailable for check m…
• judges_replay
  Create a scoring run for the current judge over a dataset's existing outputs (wraps runs_create with prompt_id omitted and output_column supplied). This only sets up the run; call runs_generate to ac…
• metric_groups_create
  Create a metric group
• metric_groups_delete
  Delete a metric group
• metric_groups_get
  Get a metric group by ID
• metric_groups_list
  List all metric groups
• metric_groups_update
  Update a metric group
• metric_versions_dismiss
  Destroy a draft MetricVersion (use for either source: 'edit' or source: 'suggestion'). Published versions are refused — to demote a published version, publish a different one as current instead.
• metric_versions_list
  List every MetricVersion (drafts + published) for a metric, newest first. Each row carries version_number, state, source, current flag, and timestamps.
• metric_versions_publish
  Publish a MetricVersion as the live version of its metric. Works for both 'draft → published' and 'revert to an older published version → current'. Transactionally flips current, demotes peers, and w…
• metrics_create
  Create a metric with evaluation criteria. For a deterministic check set metric_type:"check" and check_config. Per-kind required keys: value (contains/not_contains/equals), pattern (regex), json_path+…
• metrics_delete
  Delete a metric
• metrics_get
  Get a metric by ID
• metrics_list
  List all metrics
• metrics_suggest_variants
  Ask the model to rewrite the metric's judge instruction in N variants targeted at the recent disagreements. Each variant is saved as a draft MetricVersion with source="suggestion". Returns the persis…
• metrics_update
  Update a metric. For a deterministic check set metric_type:"check" and check_config. Per-kind required keys: value (contains/not_contains/equals), pattern (regex), json_path+expected (json_path_equal…
• promptfoo_import
  Import a promptfooconfig.yaml. Creates a prompt, a dataset from the test vars, and metrics from the assert blocks (llm-rubric/g-eval become judge metrics; contains/equals/regex/is-json become determi…
• prompts_create
  Create a prompt
• prompts_delete
  Delete a prompt
• prompts_get
  Get a prompt by ID
• prompts_list
  List all prompts
• prompts_publish
  Publish a prompt version, making it the current version
• prompts_suggest_improvement
  Suggest an improved version of a prompt, grounded in a run's test results and judge feedback. Analyzes the run's responses, scores, and reviews, then returns reasoning plus a rewritten template (pres…
• prompts_update
  Update a prompt. If the prompt already has runs, this creates a new DRAFT version (current=false) rather than editing in place or publishing — promote it with prompts_publish — so an agent's edits do…
• provider_credentials_create
  Create a provider credential
• provider_credentials_delete
  Delete a provider credential
• provider_credentials_get
  Get a provider credential by ID (API key is not exposed)
• provider_credentials_list
  List all provider credentials (API keys are not exposed)
• provider_credentials_update
  Update a provider credential
• responses_get
  Get a specific response
• responses_list
  List responses for a run, in row order. Returns {total, limit, offset, returned, responses}. Defaults to 50 rows because full payloads are large: use "fields" to drop the bodies, "min_score"/"max_sco…
• runs_create
  Create a run. Omit prompt_id and provide output_column to score existing outputs by grading a pre-existing dataset column instead of generating new ones.
• runs_delete
  Delete a run
• runs_generate
  Start a run. Required for every run, including score-only runs (no prompt): generates responses with the prompt when there is one, otherwise copies the graded dataset column and grades it.
• runs_get
  Get a run by ID, including "metric_averages": a per-metric breakdown with each metric's average score (or pass rate for checks), how many rows it graded, and how many scored low. Use this to find the…
• runs_list
  List all runs
• runs_regrade
  Re-grade a run's existing responses with its currently attached metrics, without regenerating. Use after attaching or editing metrics on an already-generated run.
• runs_rerun
  Create and start a fresh copy of a run with the same prompt, dataset, metrics, and settings. Use when the judge changed and you want a clean run instead of mixing versions.
• runs_retry_failures
  Re-run only the failed responses of a run, optionally limited to specific response ids via "only".
• runs_update
  Update a run
• tags_create
  Create a tag. Color is auto-assigned.
• tags_delete
  Delete a tag. Removes the tag from every linked metric, prompt, run, and dataset.
• tags_get
  Get a tag by ID
• tags_list
  List all tags
• tags_update
  Rename a tag.
• usage_get
  Get this organization's plan usage and limits for the current billing period: runs and prompt fetches used, their limits, how many remain, and when the period resets. Call this to pre-check quota bef…
