Grades\n  cost alongside correctness (pass-slow).\n---\n\n# Eval Grader\n\n<!-- routing-eval reads this line; it lives in the BODY so the always-on skill LISTING stays inside\n     Claude Code's budget (1% of the context window) — an overflowing listing gets descriptions\n     truncated or dropped, which strips the very keywords a match depends on. -->\nTrigger phrases: \"eval\", \"grader\", \"measure output quality\", \"LLM-as-judge\", \"score the output\"\n\n**Measure every change; don't vibe it.** When you iterate on a prompt, an agent, or any generative output (docs,\nslides, UI, a summary, an extraction), a two-layer grader over a fixed task set turns \"feels better\" into a signed\nnumber you can trust.\n\nThis is the **external, machine-grounded verifier** the `iterate` skill asks for — a model grading its *own* output\ninflates; a separate grader on a fixed suite does not.\n\n> **Kit adaptation (local, .claude/):** use when tuning a generative task; the scorecard goes to `docs/EVAL.md`\n> (§4.3). Stack-agnostic — graders are ordinary code + judge calls. §4 Prohibitions apply.\n\n## Two layers\n- **Layer 1 — code graders** (deterministic, near-free, run every time): structural metrics over the artifact —\n  *did it produce a valid result?* plus counts, sizes, schema validity, \"wall-of-text\" / clutter flags. They catch\n  gross regressions a judge shouldn't be spent on. Ground truth is **computed from the source**, not hand-authored.\n- **Layer 2 — LLM-as-judge graders** (semantic): **one call per dimension** (clarity · correctness-vs-source ·\n  completeness…), scored on an explicit rubric. Steer against leniency — \"use the full 0-5 range, not only 3-5\";\n  judge with a **different model family** to avoid self-preference; **randomize A/B order** to kill position bias.\n\nEach grader is one **scorecard column**; adding a metric = appending one grader.\n\n## pass-slow — grade cost alongside correctness\nA result is not just right/wrong. An **efficiency grader** downgrades a correct output that ran **over a\nturn/token budget** to `pass-slow` — so \"correct but too expensive\" is visible, not hidden inside a green pass.\n\n## The loop\n1. A **fixed task set** (`tasks`), each with an input and a measurable expectation.\n2. Run all graders over each task's output → a scorecard.\n3. **Pin a baseline** once; every later run shows **signed deltas vs that baseline**, not vs the previous run — so\n   re-running the same round shows real movement, not noise.\n4. Change one thing, re-run, read the deltas. Keep what moves the number up.\n\n## Noise floor\nState it. At n=20 tasks, one task ≈ 5 points — deltas smaller than that are not meaningful. If the cheapest option\nalready hits the ceiling, say so plainly instead of chasing a fractional gain.\n\n## Micro-test before you commit to a wording\nChanging an instruction — a skill's phrasing, a rule in the discipline, an agent's trigger — is a change to\nbehaviour, and the temptation is to reason about whether it reads better. Reading better and working better are\ndifferent properties. Test it cheaply first:\n\n1. **Sample it a handful of times**, not once. Same prompt, same conditions.\n2. **Against a no-guidance control** — the identical task with the instruction absent. Without the control you\n   learn what the model does, not what your wording adds.\n3. **Read every result by hand.** At this size there is no statistic to hide behind; a score computed over four\n   runs is a number pretending to be evidence.\n4. **Treat run-to-run variance as a warning, not noise to average away.** If the same arm swings across runs,\n   the wording is not doing reliable work — and any delta you measure is smaller than the variance you have not\n   controlled.\n\nThe failure this prevents, seen in this repo: a case scored 7/9 against 9/9 — the guidance apparently making\nthings *worse* — and an identical second round came back 9/9 to 9/9. Two checks of variance inverted the\nfinding. Had the first round been reported, a good rule would have been removed on noise.\n\nCorollary: a delta smaller than the observed spread between identical runs is not a result. Say \"below the\nnoise floor\" and either raise n or accept that the change is unmeasurable at this scale — both are honest;\nquoting the number is not.\n\nThe grader architecture, a starter grader catalogue, and the judge-bias checklist live in **`references/method.md`**.\n\n## DoD\n- A fixed task set + a two-layer grader; a pinned baseline; every change reported as a signed delta with the noise floor stated.\n- Any wording change was micro-tested against a no-guidance control, with every run read rather than averaged.\n","tagline":"Measure output quality, don't vibe it: score a generative task with a two-layer grader — deterministic code\nmetrics + per-dimension LLM-as-judge — over a fixed task set, as signed deltas vs a pinned baseline.
