The skill-creator `evals/` harness is the + starting seed; the factory-wide evals suite is a round-35+ + project. + +## Core principles + +### 1. The headline number is never the eval + +A single aggregate score (accuracy, pass-rate, ELO, win-rate) +hides every interesting failure mode. The eval is the +*per-item* breakdown: which cases passed, which failed, what +the failure pattern is. Report aggregates for comparison, but +do not let the aggregate be the thing reviewed. Per-item +qualitative review is the anchor. + +### 2. Eval-set contamination is assumed until disproven + +Public benchmarks leak into training sets every month. +Treat every public benchmark as partially contaminated and +supplement with private held-out sets you authored yourself +and have never shipped. If the held-out set's behaviour +diverges from the public set's, contamination is the first +hypothesis, not the last. + +### 3. Goodhart's law operates on every eval + +"When a measure becomes a target, it ceases to be a good +measure." The moment you optimise toward an eval, you are +no longer measuring the underlying capability; you are +measuring the model's ability to game the metric. Guard by: +rotating eval sets, holding out a portion you never +optimise against, tracking multiple metrics with different +goodharting shapes, re-reviewing qualitative outputs for +decay after aggregate improvement. + +### 4. The eval set distribution must match the production + + distribution + +An eval set that over-represents easy cases reports an +inflated number. One that over-represents hard cases reports +a deflated number. Neither matches production. Re-audit eval +distribution against production logs on every new eval +cycle; if production drifts, the eval set is stale. + +### 5. LM-as-judge is a measurement instrument, not an oracle + +Judge LLMs have their own biases (length preference, +position bias, judge-family preference for judge-family +outputs, refusal conservatism). An LM-as-judge eval is +valid when (a) the judge is calibrated against human ratings +on a held-out set, (b) the judge is different from the +model under test (or the test controls for same-family +bias), (c) bias checks (position-swap, length-normalisation) +are run, (d) judge-disagreement with human review on +spot-checks stays within a known envelope. + +### 6. Noise is the dominant effect on small evals + +For an eval set of size N with pass rate p, the standard +deviation on the observed pass rate is roughly +sqrt(p(1-p)/N). A 50-item eval with 40% pass has ≈7% noise; +a 2-point swing is noise, not signal. Either increase N or +do paired testing (same items, same seeds, different +condition) so the noise cancels. + +### 7. Offline evals must be bridged to online reality + +Offline evals measure on a frozen set; production is +distribution-shifting continuously. Design the bridge +explicitly: + +- **Shadow** — run the change on production traffic, score + outputs offline, no user impact. +- **Canary** — route a small percentage to the change; + monitor user-visible metrics. +- **Interleaving** — A and B outputs for the same input, + blind user choice aggregated. +- **Champion-challenger** — long-running parallel, promote + when challenger wins on a pre-declared criterion. + +Pick one per change class and document it. + +## Technique decision framework + +### Choosing a scoring mechanism + +| Scoring mechanism | Use when | Avoid when | +|-------------------|----------|-----------| +| Exact / regex match | Deterministic output (code, JSON, labels) | Any free-form text | +| Reference-match (BLEU, ROUGE, BERTScore) | Translation, summarisation with a reference | Open-ended generation | +| Rubric + LM-as-judge | Open-ended, criteria-driven (helpfulness, correctness) | Near-random tasks (judge noise dominates) | +| Pair-wise preference (G-Eval, MT-Bench shape) | Relative comparison of two systems | Absolute-quality questions | +| Human review | Everything small and high-stakes | Scale (>100 items without a budget) | +| Heuristic (length, format, keyword) | Gate before expensive scoring | As the primary metric — always a proxy | +| Execution-based (run the code) | Code / math / tool-use | Anything without ground-truth execution | + +### Choosing an eval size + +- **Smoke test (5-20 items)** — prompt-change regression, + quick diagnostic.

Diagnosis: the +benchmark is in the training set. Fix: swap to a private set +or the benchmark's post-training-cutoff variant. + +### Judge collusion + +Symptom: GPT-4-as-judge says GPT-4-output is 15% better than +Claude-output on a task where human ratings say they're +tied. Diagnosis: same-family bias. Fix: two-judge ensemble +from different families + position-swap test. + +### Format goodharting + +Symptom: adding "be thorough and give step-by-step +reasoning" doubles the pass rate. Diagnosis: the judge is +scoring length / structure, not correctness. Fix: rubric +explicitly penalising length-padding, or move to reference- +match on the final answer. + +### Regression via distribution shift + +Symptom: golden-set score stable, production complaints +rising. Diagnosis: production distribution moved off the +golden-set distribution. Fix: resample golden set from +recent production logs with a fresh random draw. + +### Spurious wins via test-set order + +Symptom: shuffling the eval set changes the aggregate +number. Diagnosis: non-determinism is being sampled, or the +judge has position bias. Fix: multiple seeds + paired +testing, report mean with CI, not single-run number. + +### "The number went up" with no qualitative audit + +Symptom: a PR bumps the aggregate from 72% to 76% and no +one read the outputs. Diagnosis: nothing is known about +*why* it went up. The delta may come from the change or +from noise. Fix: require per-item diff review for any +change; the aggregate is a summary, not the review. + +### Eval-set staleness + +Symptom: the eval was authored 6 months ago and has never +been touched.

Before adopting a + technique, produce a replication study — even a rough + one — on a benchmark you control. Most AI-research + claims do not replicate cleanly; the ones that do are + the ones worth building on. + +2. **Isolate the contribution.** Many AI papers bundle + several changes (new architecture + new data + new + tokeniser + new hyperparameter recipe) and report the + combined result. Ask: if I hold four of those five + constant and vary the fifth, does the headline effect + survive? If the authors did not run that ablation, the + paper's "contribution" is ambiguous. + +3. **Contamination is the null hypothesis.** Any benchmark + that was public before the model's pretraining cutoff + is presumed contaminated. Prefer held-out splits, + post-cutoff evaluation sets, and contamination-probing + studies. This is the same discipline as + `ai-evals-expert` applied to research claims. + +4. **Statistical power is a requirement, not a nicety.** + A paper that reports "2.3% improvement" on a 100- + example benchmark with a single run has reported + noise. Demand seeds × runs × confidence intervals + before accepting a research claim. Small AI benchmarks + have standard deviations that swallow most reported + improvements. + +5. **Compute-matched baselines.** "Our method is better + than baseline X" is meaningless if the method burned + 10× the compute X did. Always ask: does the baseline + get the same compute budget? If yes, the comparison is + meaningful; if no, the paper is confusing a compute + effect with a method effect. + +6. **Emergent-capability claims need careful framing.** + The "emergent capabilities" literature has two camps: + (a) genuine phase transitions exist at scale; (b) + most reported emergence is a metric artefact (Schaeffer + et al. 2023, "Are Emergent Abilities of Large Language + Models a Mirage?"). The AI-researcher position is + default-sceptical on emergence claims — demand smooth + metrics (log-probability, continuous scores) before + accepting a discontinuity claim. + +7. **Interpretability results must ground out in + behavioural change.** A circuit diagram, feature + visualisation, or steering-vector intervention is + interesting only if it *changes model behaviour in a + controlled way*. Pretty pictures are not evidence. + Grow the chain: proposed mechanism → steering + intervention → observed behavioural change → measured + ablation of the intervention. + +8. **Alignment and capability are entangled.** Every + capability improvement is potentially an alignment- + surface change; every alignment intervention can + degrade capability on distribution. Evaluate both + surfaces on the same model. Single-surface reports + are insufficient evidence. + +## Decision table — paper triage + +| Signal | Action | +|--------|--------| +| New benchmark, no held-out split | Dismiss; contamination-risk dominates. | +| Headline number, no seed variance | Hold; ask for seed × runs. | +| Ablation removes all structural changes | Accept the claim more confidently. | +| Ablation changes single axis only | Accept the mechanism claim; suspect interaction effects. | +| No compute-matched baseline | Hold; demand the matched baseline. | +| Novel technique, wall-clock unreported | Hold; wall-clock is often the hidden limiting factor. | +| Mech-interp claim with no behavioural ablation | Dismiss the causal claim; retain as descriptive. | +| Alignment paper with no capability regression test | Hold; ask for capability impact. | +| Scaling-law paper, single model family | Hold; ask for replication on a second family. | + +## Decision table — replication effort + +| Claim type | Minimum replication cost | +|-----------|--------------------------| +| Prompt-engineering trick | Hours; a few dozen test cases. | +| Fine-tuning method on existing dataset | Days; single GPU if dataset is public. | +| Novel architecture at small scale | Weeks; paired with compute-matched baseline. | +| Scaling-law claim | Months; multiple sizes, multiple seeds. | +| Alignment technique (RLHF / DPO) | Weeks; reward-model training + eval suite. | +| Interpretability circuit claim | Days; if you have the model weights, run the ablation. | +| Agent-system benchmark result | Days-weeks; agent scaffolding is fragile and often the limiting factor. | + +## Common failure modes + +- **Confusing the chart with the claim.** A graph shows + numbers; the claim is what the graph *entails*.
