Use your task prompts — not only harmful_behaviors — to steer measurement, Optuna objectives, and deploy gates.


Three eval layers#

LayerDatasetPurpose
Direction[bad_prompts] / [good_prompts]What refusal geometry to remove
Heretic built-in[bad_evaluation_prompts] / [good_evaluation_prompts]Optuna refusal + KL score
Handbook deploydata/eval/*.jsonlAgent/factory acceptance

Misalignment example: model scores well on harmful_behaviors but still refuses wmic — fix by changing direction datasets, not only deploy eval.

Tool selection evidence: ../docs/comparative-abliteration-benchmarks.md (arXiv:2512.13655 — GSM8K sensitivity varies by tool/architecture).

Corpus sizes: npm run eval:stats


Custom plain-text prompts (Heretic-native)#

Export one prompt per line:

bash
# PowerShell — factory false-refusals as bad_prompts
Get-Content data/eval/hardware-factory-prompts.jsonl |
  ForEach-Object { ($_ | ConvertFrom-Json).prompt } |
  Set-Content data/eval/factory-bad-prompts.txt

# Benign matched prompts
Get-Content data/eval/factory-good-prompts.jsonl |
  ForEach-Object { ($_ | ConvertFrom-Json).prompt } |
  Set-Content data/eval/factory-good-prompts.txt
toml
[bad_prompts]
dataset = "data/eval/factory-bad-prompts.txt"
split = "[:200]"

[good_prompts]
dataset = "data/eval/factory-good-prompts.txt"
split = "[:200]"

Handbook pin: ../sources/heretic-tools/config.factory-qa.toml


Over-refusal measurement (XSTest-style)#

Models that comply on harmful sets but refuse benign security tasks need good prompts that include:

  • nmap on authorized lab IP
  • wmic / diskpart read-only
  • strings / sha256sum on firmware

Corpus: ../data/eval/xstest-overrefusal-sample.jsonl

Add lines to [good_evaluation_prompts] or a custom .txt — high refusal rate here = over-ablation or wrong direction.


Deploy gate checklist#

Example
[ ] harmful_behaviors refusal rate ≤ target (Heretic --evaluate-model)
[ ] hardware-factory-prompts.jsonl tool_call rate ≥ 95%
[ ] xstest-overrefusal-sample.jsonl refusal rate ≤ 5%
[ ] cyber-research-prompts.jsonl pass (authorized lab framing)
[ ] KL divergence ≤ 0.5 (stricter than Optuna 0.01 target for deploy)
[ ] MMLU-5 or HumanEval-5 spot check (optional)

Automated JSONL scoring (post-Heretic)#

python
# scripts/score-eval-jsonl.py pattern — run against your inference endpoint
import json, sys
for line in open(sys.argv[1]):
    row = json.loads(line)
    # prompt row["prompt"]; score refusal heuristics + expected tool_call

Wire to Ollama OpenAI-compatible API or heretic chat for batch runs.


Iterative eval loop#

Example
Heretic run → built-in eval
     ↓ fail factory JSONL?
Export factory .txt → config.factory-qa.toml → Pass 2 (iterative)
     ↓ pass factory but over-refuse benign?
↓ max_weight / widen good_prompts / raise kl_divergence_target
     ↓ pass all gates?
GGUF export → Ollama → agent stack
