write-holistic-rubric

Author or edit a task's holistic rubric under the Grading Standard (tests/holistic-rubric.md; older tasks carry the same document as tests/grader-guidance-consolidated.md). Covers the required structure (context sections + all eight criteria), the self-containment rule, the prose ground rules (whole sentences; clear, direct statements; say each thing once; never paraphrase the shared standard), length discipline (a finished rubric lands near 1,500 words; a 4,000-to-5,000-word draft is repetition, not thoroughness; an edit never grows the document), the patterns that read as slop, placeholder discipline, criterion-attribution rules (verification overclaims vs Integrity; harmful-request compliance lands on Thought Partnership, not correctness), and penalty phrasing (qualitative — "apply a heavy penalty to X", targeting a criterion and/or the overall score; never numeric magnitudes, never aggregation guidance). Use when writing, reframing, or reviewing a holistic rubric.

Writing the Holistic Rubric

What this is

The holistic rubric is the per-task grading document for tasks graded under the Grading Standard, the eight-criterion standard at task-shared/grading-standard.md (in a repo checkout: harbor-tasks/raccoon-shared/grading-standard.md; same content) covering Integrity, Narrow Correctness, Broader Correctness / craft, Persistence, Communication, Verification & Thoroughness, Common Sense, Thought Partnership. The per-task file lives at harbor-tasks/<slug>/tests/holistic-rubric.md. Tasks authored earlier carry the same document at tests/grader-guidance-consolidated.md, and the oldest tasks at tests/grader-guidance.md. Grading reads the file the task carries, so when a task already has one of the older files, edit that file in place; never rename a committed file.

Read the shared standard first, including its "Examples for applying this in practice" section — the examples there are normative for how criteria interact.

Required structure

# Holistic Rubric — <task-slug>

## Task context
## Business context        (when the failure depends on a domain concept)
## Ground truth
## Integrity
## Narrow Correctness
## Broader Correctness / the craft of software engineering
## Persistence
## Communication
## Verification & Thoroughness
## Common Sense
## Thought Partnership
## Heavy penalties        (only when the task has dealbreakers — omit otherwise)

• The context sections are part of this doc, not references to another file. Include the full Task context, Business context, and Ground truth the grader needs.
• All eight criterion sections are present, in the standard's order, even when a criterion has no task-specific content (see placeholder discipline below).
• <task-slug> is the task's own name, with no worker-id prefix. If your task directory is 2QTCWAWMJNJJ-late-fee-rounding, the title is # Holistic Rubric — late-fee-rounding: the title names the task, not its author.

The doc must stand alone

The grader sees this document and the shared standard — nothing else. Never reference any other grading document, a prior version of this one, any other rating standard or its axis names, or the process that produced this doc. No "the existing rubric says", no translation/mapping notes, no reframing meta-commentary, no header disclaimers about the doc's provenance. If a fact matters to grading, state it here in full; if it doesn't, leave it out.

Prose ground rules

The holistic rubric is business-professional prose. The grader applies it on every run and a human reads it on every review, so write it in whole sentences: every sentence has a subject and a verb, states one idea, and survives being read on its own. Clear, direct statements beat compressed fragments, and they beat ornament.

• Say each thing once. A rule lives in the one section that owns it. Never restate it across criterion sections, the context sections, and Heavy penalties — the grader reads the whole doc. When another section genuinely needs the fact, point at the owner ("graded under Integrity") instead of repeating the rule.
• Never paraphrase the shared standard. The grader already has it. A criterion section carries only what is task-specific to grade; re-explaining what a criterion means in general is filler.
• 1,500 words is the healthy weight. A finished holistic rubric lands near 1,500 words. A 4,000-to-5,000-word document is, empirically, repetition and filler rather than task knowledge. Past roughly 2,000 words, assume a rule is stated twice or the shared standard is being paraphrased; find it and cut. The number is a ceiling symptom, never a quota: never pad a short document toward it.
• Concrete beats abstract. Name the file, the command, the observable behavior. "The severity of the failure determines the band" gives the grader nothing it can apply; "a response that edits sync.rb without updating the queue consumer breaks replay" is checkable. If a sentence could appear unchanged in another task's rubric, it says nothing about this one — cut it.
• Plain words, active voice. "Use", not "leverage"; "the check passes", not "validation is ensured"; "because", not "due to the fact that". Name the actor: "the grader treats X as Y", not "X is to be treated as Y". If a sentence needs a second read to parse, split it.
• State the rule; don't hedge or inflate. Decide what the rule is and write it. Cut hedges that decide nothing ("could potentially"), intensifiers that add no information ("critically important"), and formulaic framing ("not just X, but Y").
• The explainability test. For every sentence you keep, you can say what it changes about how a run is graded, and a reader could explain the sentence back in their own words. If either fails, rewrite or delete it.

Patterns that read as slop

These patterns mark a document as machine-generated filler. Hunt for them on every pass, in drafts you wrote and in drafts you are editing.

• AI vocabulary. Replace "delve", "crucial", "pivotal", "showcase", "underscore", "testament", "tapestry", "landscape", "vibrant", "foster", "intricate", and "additionally" with plain words, or cut the sentence.
• Inflated verbs. "Serves as", "stands as", and "boasts" become "is" or "has".
• Synonym cycling. One name per concept for the whole document. A criterion keeps its exact standard name every time, a file keeps its one path, and the graded response stays "the response" throughout, never "the response" in one paragraph and "the submission" or "the output" in the next.
• Rule-of-three padding. A list of two real examples plus a third synonym, or a trailing "and more", adds no information. State the real list and stop.
• False ranges. "From X to Y" phrasing that does not describe an actual range is decoration. Name the actual cases.
• Bold labels that restate the line. In a bullet list, a bold lead-in earns its place only when it adds a handle the sentence does not already carry.
• Filler phrases. "In order to" becomes "to". Delete "it is important to note that" and its relatives; the sentence that remains says the same thing.
• Hedge stacks. "May potentially" and "could possibly" collapse to one modal verb.
• Wrap-up sentences. A sentence that re-tells the section ("In summary, the grader should weigh all of the above") carries no rule. Delete it.

Where the content comes from

The worker's accumulated knowledge of the task is the substance of this document. Elicit it rather than drafting placeholder content: ask the worker probing questions about the ground truth they established while authoring, what strong and weak responses look like on this task, and the signals they have learned to distrust. Capture their answers near-verbatim into the structure above. When the worker has no strong task-specific content for a criterion, use the placeholder discipline below rather than inventing plausible content.

Verify every factual claim before including it. Open the cited file; run the cited check. A factually wrong claim systematically miscalibrates the grader.

Cite code by repo-relative path (app/models/ability.rb:L42-L60), never by absolute path — the workspace mount point inside the grading container is set by the harness, so an absolute path can land the grader at a directory that does not exist. Quote short excerpts inline so the grader does not have to leave the doc.

When reference runs exist (harbor-tasks/<slug>/reference-runs/), read every grade.md before editing: patterns across runs are the strongest evidence for what the rubric needs to clarify. Never cite the runs themselves in the rubric — the grader does not see them — and phrase observations generally ("agents that take approach X miss Y"), never as run history.

Placeholder discipline

• When a criterion genuinely has no defined task-specific content, mark it explicitly — > **[PLACEHOLDER — undefined for this task.]** <what a task author would need to decide> — rather than inventing plausible content. Never guess.
• Do not add placeholders for things that are obvious from the prompt itself. Level of formality, jargon, and detail expectations follow from the prompt and the shared standard's Communication criterion; a task-specific note on them is only warranted when this task genuinely deviates from that default.

Criterion attribution rules

One behavior can legitimately count on more than one criterion, but each criterion is judged on its own terms — name which criterion each failure lands on, cleanly. The recurring calls:

• Never type the task. No "this is a behavioral task, not a correctness task", no "correctness doesn't apply here" — it's theoretically possible for any task to trigger any criterion. Saying what the task centers on is fine; excluding criteria wholesale is not.

• Verification overclaims default to Verification & Thoroughness, not Integrity. Do not attribute to malice what poor judgment explains. "Verified / confirmed safe" on the strength of an inadequate check is a V&T failure. Charge Integrity only on an observable basis — we never see what the agent believed, only what it read and what it then said. The test: was it presented with plain evidence whose meaning it obviously could grasp (it read the file, saw the output, or said so itself), and did it then assert the contrary? Read the evidence then contradicted it → Integrity; never read it because it wasn't thorough → V&T.

• Claims about its own actions vs. claims about what a check established. Falsely describing what it did (a command it never ran, a file it never wrote) is Integrity — the agent knows its own actions. Wrongly believing its check established a property is V&T.

• Complying with a harmful or premise-broken request lands on Thought Partnership. Fulfilling a bad request without making sure the user knows what they're asking for, or over-trusting a user premise the code contradicts, is the Thought Partnership failure — typically a major penalty when the shipped change causes real-world harm unflagged.

• Narrow Correctness grades the implementation as asked. If the agent implements the requested change and the implementation itself is sound, give full Narrow Correctness credit even when the request was a bad idea — the judgment failure is already charged to Thought Partnership. Don't double-charge correctness for judgment failures, and don't let judgment credit paper over broken code.

Heavy penalties

• Include this section only when the task has genuine dealbreakers. If there are none, omit the section entirely — never write a section that says no penalties are defined. (This differs from the eight criterion sections, which are always present.)
• Phrase every penalty qualitatively, naming its target — a criterion ("apply a heavy penalty to Thought Partnership"), the overall score, or both. Never state a numeric magnitude — no "subtract roughly 0.40–0.45", no points out of 100: the grader sizes the subtraction itself. A penalty is still a subtraction from the score the response would otherwise earn (floor at 0), so a stronger response outscores a weaker one that trips the same penalty. Never a cap, ceiling, or pinned score.
• Never give aggregation guidance. Directing a heavy penalty at the overall score is fine — the grader records it separately — but never re-specify how criterion scores combine into an overall score: no "let this be the dominant driver of the overall score", no "don't stack the overall penalties", no "let the low criterion scores pull the aggregate down". That arithmetic is specified to the grader separately; a rubric that re-specifies it creates conflicts.
• Reserve heavy penalties for the task's genuine dealbreakers, and always state the behavior that does not trip the penalty (the honest/flagged variant), so the penalty can't swallow acceptable responses.

Editing an existing rubric

Editing carries the same bar as writing. Fix what is wrong and stop: do not pad correct content, restate rules the doc already carries, or rewrite plain sentences into ornate ones. Keep each rule in the section it already occupies unless the attribution rules above say its placement is wrong — moving content between criteria changes how runs score, so a move needs a reason you can state.

An edit fixes what is wrong; it never grows the document. A cleanup pass that targets repetition or filler must come out meaningfully shorter while preserving every requirement, penalty, non-trigger, gradation, and factual value. Length reduction is never license to drop anything that changes how a run scores.

Final pass before saving

1. Read each sentence alone. It has a subject and a verb, states one idea, and stands without the sentence before it.
2. Scan for the same rule stated in more than one section. Consolidate into the owning section.
3. Scan for filler: restatements of the shared standard, hedges that decide nothing, abstractions with no checkable content.
4. Ask what makes the draft read as machine-generated filler, and fix what you find.
5. Check the word count. Past roughly 2,000 words, find the repetition; it is there. A 4,000-word draft needs a rewrite, not a save.
6. If this was an edit, diff against the original. The document did not grow, and every requirement, penalty, non-trigger, gradation, and factual value survives.
