When I started building eval-harness in May 2026 I evaluated promptfoo first. I still recommend it for most teams. + +This page is the honest answer to **"why does eval-harness exist if promptfoo already does this?"** It's organized around four things eval-harness does that promptfoo doesn't, and three things promptfoo does that eval-harness doesn't. + +> **One-line summary:** promptfoo is a great _eval framework_. eval-harness is a focused _regression-detection harness_. They solve different problems and compose well. + +## What eval-harness does that promptfoo doesn't + +### 1. Failure attribution (the killer feature) + +When a promptfoo test fails, you get `expected`, `actual`, and a diff. You then spend 20–60 minutes asking yourself: + +- _Did my prompt change?_ +- _Did the model change under me?_ +- _Did the fixture rot?_ +- _Is this flaky?_ + +eval-harness ships a 4-class attribution decision tree that answers that question deterministically using SHA fields captured at baseline + at run time: + +``` +[FAIL] atom-tags-decision-architecture +Attribution: SKILL_CHANGED (skill_sha 7f3a2c1 → 9d4e1b8, only delta) +``` + +That's not a magic ML thing. It's a simple ledger: at baseline time we hash the skill, the fixture, and capture `model_id` + `opencode_version`. At fail time we compare. The class that diverged is the class that explains the failure. + +promptfoo doesn't have an analogous concept. You _could_ reconstruct it manually from git log + provider metadata. We did it for you. + +### 2. The 6-field FAIL schema (not just expected/actual) + +promptfoo gives you: + +``` +✗ output: did not match /yes/i + received: "I cannot answer that question." +``` + +eval-harness gives you (per FAIL): + +| Field | Value | +|---|---| +| `failed_check_id` | `atom-tags-decision-architecture` | +| `expected` | `$.atoms[].tags[] contains "architecture"` | +| `actual` | `["redux","redaction"]` | +| `diff_hint` | `tag "architecture" missing from atom #2` | +| `transcript_span` | `lines 142-158 of opencode.log` | +| `env_delta` | `skill_sha 7f3a2c1 → 9d4e1b8 (only delta)` | + +`transcript_span` and `env_delta` are the two that compound. `transcript_span` lets you jump to the exact place in the log where the LLM produced the wrong thing. `env_delta` overlaps with attribution above but is also a standalone forensic field. + +### 3. Honest flaky tagging + +When a test fails in promptfoo, you re-run it. If it passes, you assume it was flaky and move on. + +That hides bugs. + +eval-harness re-runs 3× on FAIL and hashes the outputs byte-for-byte: +- **All 3 identical** → real FAIL, attribute it +- **Any divergence** → tag `flaky: true`, don't attribute + +The flaky tag is **first-class**. You see it in `diff.md`. It's recorded in `history.ndjson` so you can chart your suite's flakiness over time. promptfoo treats flakiness as a CI-runner problem; we treat it as a signal. + +### 4. $-cost hard ceiling + +promptfoo tracks token cost. eval-harness **enforces** it: + +```bash +export EVAL_BUDGET_USD=2.00 +``` + +When you blow $2.00 in one day, the harness aborts before the next call. With a clear message. No surprise $400 Anthropic invoice on Monday. + +This matters more than it sounds. The single biggest reason teams turn off LLM eval in CI is "it costs too much." Hard cap fixes that. + +## What promptfoo does that eval-harness doesn't + +### 1. Provider matrix + +promptfoo supports 50+ providers. We support whatever your runner supports (today: opencode → Anthropic). If you need to A/B Claude vs GPT-4 vs Gemini, **use promptfoo**. + +### 2. Scenario libraries + redteam + +promptfoo ships dataset management, scenario libraries, and a full redteam suite. We don't. Different problem. + +### 3.

A 6-field FAIL schema (instead of expected/actual): adds `transcript_span`, `env_delta`, `diff_hint`, `failed_check_id`. The `env_delta` field captures what changed in the environment since baseline — that's the single biggest debugging time-save. + +2. 4-class attribution. A simple decision tree over SHA fields says SKILL_CHANGED, FIXTURE_STALE, MODEL_CHANGED, or UNKNOWN_DRIFT. Anthropic shipped 4 minor revisions of claude-3-5-sonnet in 2024 without announcing them.

[I checked the model version field](https://docs.anthropic.com/) and saw four un-announced point releases of sonnet through 2024. + +The wasted hour wasn't the model's fault.

That tool didn't exist. So I built it. + +This is the design write-up for the attribution layer. + +### The 4 classes + +Every failure gets exactly one class: + +| Class | What changed since baseline | What you should do | +|---|---|---| +| `SKILL_CHANGED` | Your skill file SHA differs | Read the diff. Fix the skill, or accept the new behavior. | +| `FIXTURE_STALE` | Your fixture directory SHA differs (but the skill doesn't) | Bless the fixture. `eval-harness accept --case `. | +| `MODEL_CHANGED` | `model_id` or runtime version differs (but skill + fixture don't) | Anthropic shipped a model change. Decide if the new behavior is acceptable. | +| `UNKNOWN_DRIFT` | None of the above | Run the 3-sample stability check. If unstable → flaky. If stable → file a bug. | + +That's the whole layer. **It's not a probabilistic classifier.** It's a decision tree over four SHA fields captured at baseline time and re-captured at run time. The whole implementation fits in one bash file: [`scripts/eval/lib/attribute.sh`](https://github.com/nano-step/eval-harness/blob/main/scripts/eval/lib/attribute.sh). + +### Why 4 and not 3 or 7 + +I went through several variations before landing on 4. The discarded ones tell you about the constraint. + +**3 classes (skill / fixture / unknown)**. Loses `MODEL_CHANGED`, which is the single most common cause of mystery regressions in 2025-2026. Rejected. + +**7 classes (split UNKNOWN into MCP_FLAKE, HARNESS_BUG, NETWORK_TIMEOUT, RATE_LIMIT, …)**. I designed this and shipped it for a week. Then realized I couldn't reliably distinguish MCP_FLAKE from HARNESS_BUG without false positives. **Honesty beat false precision.** The signal collapsed into UNKNOWN_DRIFT with a note that the 3-sample stability check would catch flake. + +**5 classes (add PROMPT_INJECTION)**. Tempting because LLM red-team detection is a hot topic. Wrong concern. Prompt injection isn't a regression class; it's a separate eval category. I added a future `skill-reviewer` tool to the roadmap and kept attribution focused. + +The lesson: **fewer classes you can defend > more classes that pretend.** Anyone who claims 12 attribution categories is either over-fitting or selling something. + +### The env-manifest is the lynchpin + +The thing that makes attribution work is the env-manifest captured at baseline time: + +```json +{ + "skill_bundle_sha": "sha256:9d4e1b8...", + "skill_sha": "sha256:7f3a2c1...", + "fixture_sha": "sha256:e8d29a4...", + "model_id": "claude-3-5-sonnet-20241022", + "opencode_version": "1.15.2", + "platform": "darwin-arm64", + "captured_at": "2026-05-30T11:42:08Z" +} +``` + +Without `model_id` you cannot detect MODEL_CHANGED. Without `skill_bundle_sha` you cannot detect cross-skill interaction breaks (which DO happen — skill A's regex changes how skill B parses input, even though B is byte-identical). + +Most eval tools either don't capture this manifest at all or capture only `expected/actual`. The manifest is **cheap** (kilobytes), the math is **trivial** (SHA comparison), and the payoff is the difference between "test failed" and "test failed and here's exactly what changed." + +### The stability check catches the false positives + +A failure with attribution = `UNKNOWN_DRIFT` is rare but it does happen. The decision tree says "nothing in your environment changed but the test failed." That's either: + +1. A real intermittent bug (race condition, MCP server flake, network blip) +2. LLM jitter at temperature > 0 +3. A bug in the harness itself + +To separate (1) and (3) from (2), eval-harness re-runs the failing case 3 times and hashes outputs byte-for-byte. If all 3 are identical, it's a real failure — file a bug. If any divergence, tag `flaky: true` and don't pretend you can attribute it. + +This is the part where most eval tools cheat by silently retrying until pass. eval-harness records the flake.

No more. Below: what each saves you. + +### 1. `failed_check_id` — the grep handle + +Stable identifier so you can grep history. `atom-tags-decision-architecture` is the same string in every run. You can chart how often it fails, when it started failing, whether it co-fails with other cases. + +Most eval tools use a synthetic numeric ID that changes between runs. That makes "show me the test that broke last week" impossible without ad-hoc parsing. + +**Saves**: history queries, regression-pattern detection. + +### 2. `expected` — verbatim from YAML, not paraphrased + +`$.atoms[].tags[] contains "architecture"` is the **literal text** from the case YAML. Not a paraphrase. Not a humanized version. The verbatim assertion. + +Why this matters: when you're debugging the failure, you want to copy-paste the assertion into a REPL and reproduce the check manually. Paraphrased text wastes 5 minutes finding the original. + +**Saves**: manual reproduction. + +### 3. `actual` — structured, not stringified + +`["redux", "redaction"]` is the actual array value extracted via the jq path. Not the whole LLM transcript. Not a serialized string. + +When the check is structural (jq_path_contains, file_exists, output_contains), `actual` is the structural value. When the check is shell-based, `actual` is stdout. Match the **shape of the check** with the **shape of the actual**. + +Most tools give you "the LLM output" verbatim, even when the check only cares about one slice of it. You then have to grep for the slice manually. + +**Saves**: 30 seconds per FAIL × N FAILs × 12 weeks. Compounds. + +### 4. `diff_hint` — one sentence narrowing the gap + +`tag "architecture" missing from atom #2` + +This is what most tools don't emit because it requires the harness to *understand* the check kind. It's just one sentence — but it's the one sentence that points your eyes at the right column of the right row. + +For `kind: shell`, the diff_hint is the longest common substring difference. For `kind: jq_path_contains`, it's "value at $.foo[N] differs." For `kind: llm_judge`, it's the rubric sentence the judge marked unsatisfied. + +Generated mechanically. No LLM call. Just a small lookup table per check kind. + +**Saves**: cognitive load. You stop scanning expected/actual line-by-line. + +### 5. `transcript_span` — the line range in the agent's log + +`lines 142-158 of opencode.log` + +This is the killer field. Every other tool gives you the LLM output as a blob. eval-harness tells you the **exact line range** in the agent transcript where the relevant output was emitted — so you can: + +- Jump to those lines in your editor +- See what tool calls preceded the output +- See whether the agent reasoned its way to the wrong answer or panicked + +For tool-use agents (Claude with tools, LangGraph nodes, opencode skills), the transcript_span includes the surrounding tool_use blocks.

Same input, same model, same temperature 0 — you can still get subtly different outputs across runs. Whitespace, word ordering in a list, the specific phrase the model uses to refuse. + +Most CI systems handle flake by **retrying until pass**. This is wrong for LLM tests because it hides genuine intermittent bugs. + +eval-harness does something different. When a case fails, it re-runs 3 times and hashes the outputs byte-for-byte. + +- **All 3 identical** → real FAIL, attribute it. +- **Any divergence** → tag `flaky: true`, don't attribute. + +That's the whole technique. ~30 lines of bash. This post is why it works, why 3 (not 5 or 2), and how to compose it with attribution. + +### The hash needs normalization + +You can't hash raw stdout directly. Two genuinely identical LLM responses can differ in: + +- Trailing whitespace per line +- ANSI color codes if the runner prints them +- Tool-call arg ordering (Claude sometimes lists `tool_use` args in different orders even at temperature 0) + +eval-harness normalizes before hashing. The normalizer ([`scripts/eval/lib/stability.sh`](https://github.com/nano-step/eval-harness/blob/main/scripts/eval/lib/stability.sh)) does: + +1. Strip ANSI escape codes (`sed 's/\x1b\[[0-9;]*m//g'`) +2. Collapse runs of whitespace to single spaces +3. Trim line trailing whitespace +4. Sort tool_use args by key when they appear in the transcript JSON +5. Drop trailing empty lines + +After normalization, `sha256sum` over the result. Three samples produce three hashes. Compare: + +```bash +if [[ "$h1" == "$h2" && "$h2" == "$h3" ]]; then + verdict="real" +else + verdict="flaky" +fi +``` + +### Why 3 samples, not 2 or 5 + +**2 samples**: false negatives are too easy. If the model produces 80% of outputs identically and 20% jitter, two samples have a 36% chance of matching by coincidence even when the underlying behavior is unstable. + +**5 samples**: triples the API cost on every FAIL with marginal precision gain. For an 80/20 model, 3 samples already give ~51% probability of catching the jitter; 5 gives ~67%. Not worth the dollars on a CI gate. + +**3 samples** is the sweet spot: 51% catch rate of 80/20 jitter, 3× cost on FAILs only (passing cases never get extra samples), and the hash comparison is dead simple. + +If you want to tune: `EVAL_STABILITY_SAMPLES=5` overrides the default. We don't recommend it for cost reasons but the lever exists. + +### Composition with 4-class attribution + +The stability check sits *upstream* of attribution. The pipeline: + +``` +case FAILs + │ + ├──> 3-sample stability check + │ ├── all identical → real FAIL + │ │ │ + │ │ └──> 4-class attribution (SKILL_CHANGED / FIXTURE_STALE / MODEL_CHANGED / UNKNOWN_DRIFT) + │ │ + │ └── divergence → tag `flaky: true` + │ │ + │ └──> SKIP attribution (don't pretend you can blame a class) + │ + └──> render diff.md +``` + +The crucial bit: **flaky cases don't get attributed.** A common bug in eval tooling is to attribute a flake as `UNKNOWN_DRIFT`, which makes the dashboards lie. eval-harness explicitly carves out flakiness so the attribution stats stay honest. + +### What `flaky: true` does to your workflow + +In `history.ndjson`, every case run records `flaky` as a boolean. You can chart flakiness rate over time: + +```bash +eval-harness trend --since=30d --flaky-only +``` + +If your flakiness rate climbs above ~5% of total runs, something in your suite needs tightening. Common causes I've seen: + +- **LLM-judge rubrics that are too vague.** "Is the answer helpful?" → flake. "Does the answer contain at least one URL?" → deterministic. +- **`output_contains` checks on long generation.** The LLM's wording varies; the substring is too narrow. Widen to a regex. +- **MCP server flake** (Anthropic's MCP tool calls occasionally fail upstream; not your bug). +- **Real intermittent bug** in your tool-use logic. + +The trend gives you the signal. You decide which. + +### What about pass@k? + +If you've shipped LLM evals, you've probably heard of [pass@k](https://arxiv.org/abs/2107.03374) — "the test passes if at least k of N samples pass." It's the standard technique in academic benchmarks. + +eval-harness will support pass@k as an opt-in mode ([issue #21](https://github.com/nano-step/eval-harness/issues/21)) but it's not the default because: + +- pass@k accepts flakiness silently. Your CI passes even when the LLM is unstable. That's wrong for a regression-gate. +- pass@k requires 5-10 samples per case. Cost grows linearly. +- pass@k makes attribution impossible (which sample "really" failed?). + +For benchmark numbers, pass@k is right. For CI gating, 3-sample byte-identical is right. + +### Try it + +The stability check is on by default in v0.4.2. Any FAIL automatically gets re-run 3 times. You'll see `Stability check: 3 samples byte-identical → real FAIL` or `Stability check: samples diverged → flaky` in `diff.md`. + +```bash +npm install -g @nano-step/eval-harness +eval-harness run --skill +``` + +Implementation: [`stability.sh`](https://github.com/nano-step/eval-harness/blob/main/scripts/eval/lib/stability.sh). +Test coverage: [`stability_inline.sh`](https://github.com/nano-step/eval-harness/blob/main/scripts/eval/tests/stability_inline.sh). +Repo: [github.com/nano-step/eval-harness](https://github.com/nano-step/eval-harness). + +### Open question + +The technique works well in practice but I haven't found a clean theoretical framing for it.
