Comparing competitors

A prompt's competitor benchmark comes from sub-prompts, not from any URL list. get_prompt_benchmarks assembles the whole picture — every lane and its run history; get_report fills in the per-run detail for specific slugs.

Where competitor identity comes from

Competitors are sub-prompts: rows whose parentPromptId points at the parent prompt and whose targetProviderId names the competitor provider. Each sub-prompt runs the same task against a different provider. Do NOT derive competitors from a parent prompt's URL list or additionalUrls — sub-prompts are canonical. get_prompt_benchmarks already does this resolution for you.

Tools

• get_prompt_benchmarks({ promptId }) — the primary tool. Returns:
  • prompt: { id, title, text, endGoal, orgDomain }
  • self: { provider, runCount, latest, history[] } | null — the "you" lane (the prompt's own provider).
  • competitors: [ { provider, runCount, latest, history[] } ] — one lane per competitor sub-prompt.
  • Each lane's latest/history[] item is { slug, timestamp, score, grade, status, metrics, runType }. provider is { id, slug, name, url }. This mirrors the prompt-detail page the user sees. The per-lane history[] (ordered oldest→newest) is your trajectory source — read it for "closing the gap" vs "falling behind", not just point-in-time.
• get_report({ slug }) — pull the full per-run detail (metrics, legacy.frictionPoints, legacy.keyFinding, summary, recommendations) for a specific slug once you've picked runs to contrast (e.g. each provider's latest.slug from get_prompt_benchmarks). To compare two runs, fetch each slug and diff their metrics yourself. Note: score, grade, and dimensions are no longer part of the report output.
• list_prompts() — to find the parent promptId (it lists top-level prompts only; competitor sub-prompts are intentionally excluded).
• list_sub_prompts({ promptId }) — a lighter lookup when you only need the competitor lanes themselves (id, status, targetProvider: { id, slug, name, url }) and not their run history; prefer get_prompt_benchmarks once you're actually comparing runs.
