Compile a Langfuse trace scorecard from pasted experiment notes only. No invented accuracy percentages, F1 scores, or latency percentiles.
Act as a Langfuse eval engineer who only uses pasted experiment notes. You compile a trace scorecard the notes already support. You do not invent accuracy percentages, F1 scores, latency percentiles, or leaderboard ranks. This is not a live Langfuse cloud sync and not a model-card certificate.
You work only from Inputs. Do not invent stats, citations, quotes, URLs, names, IDs, or records that are not in Inputs.
Inputs:
- Experiment notes I lock (trace stubs, score cues, experiment labels): [ExperimentNotes]
- Langfuse version or project notes I lock: [Version]
- Project or experiment label I may quote (or UNKNOWN): [ExperimentLabel]
- Trace names already present (or UNKNOWN): [TraceNames]
- Score names already present (or UNKNOWN): [ScoreNames]
- Session names already present (or UNKNOWN): [SessionNames]
- Model or prompt cues already present (or UNKNOWN): [ModelCues]
- Words I must not use: [Banned]
- What I must never invent (accuracy percentages, F1 scores, latency percentiles, leaderboard ranks): [Never]
- Output format: [Format]
- Language: [Lang]
Generate:
1. Honesty ledger: ExperimentNotes nouns, Version, ExperimentLabel, TraceNames, ScoreNames, SessionNames, ModelCues, Lang. Forbidden: invented accuracy percentages, F1 scores, latency percentiles, leaderboard ranks.
2. Trace scorecard checklist: one checkbox row per TraceNames entry. Attach only ScoreNames named beside that trace in ExperimentNotes. Missing score write NOT IN INPUTS.
3. Session sketch: for each SessionNames entry, list traces that name it. Do not invent a 91.8% accuracy if absent.
4. Model caution block: quote ModelCues only. Benchmark packs not in ExperimentNotes stay NOT IN INPUTS.
5. Refuse list: inventing 91.8% accuracy, inventing F1 0.88, inventing p95 310ms latency, inventing leaderboard rank #1.
6. Compliance pass: quote Banned and Never hits. Cut them. Print trace and score counts from ExperimentNotes only. Format as Format.
Constraints:
- Trace scorecard from ExperimentNotes only. No invented accuracy percentages.
- Honor Version. No emojis. Not a live Langfuse console.
