Update question

update_question

Destructive

Update a single question of an existing form, located by code. Changeable: name / description / explain / required / score / correctAnswer / aiMatch (FillBlank AI grading) / precision (DateField/TimeField picker precision) / min / max / unit / decimalPlaces (NumberField) / words (Rate scale labels) / choices (replaces ALL choices of a choice-based question). NOT changeable — delete_question then add_question instead: question type, Rate steps, DropDown multiple, Ordering shuffle. DateField / TimeField / Rate reject score / correctAnswer / aiMatch (configure date/time scoring in the web app). The scored_quiz and outcome_quiz scenes reject the top-level score / correctAnswer / aiMatch as well: pass choices carrying choices[i].score or choices[i].outcomes instead (TrueFalse outcome votes still need delete + recreate). Display blocks are edited here too, with their own keys: Statement takes content, Swiper takes items (replacing all slides), and both take name / description — every question key is rejected on them.

Input Schema

TableJSON Schema

Name	Required	Description
`max`	No	NumberField only: new maximum allowed value; pass null to remove the upper bound. Ignored for other question types.
`min`	No	NumberField only: new minimum allowed value; pass null to remove the lower bound. Ignored for other question types.
`code`	Yes	Question code (field.code), from the get_form / create_form return value
`name`	No	New question stem, optional
`unit`	No	NumberField only: new display unit suffix (e.g. "kg"); pass null or an empty string to clear. Ignored for other question types.
`items`	No	Swiper block only: replace ALL slides with this list (1-10). Slides get fresh ids, so any translated slide titles / notes for this block have to be rewritten afterwards.
`score`	No	Score for this question; 0 or omitted + no correctAnswer means not scored
`words`	No	Rate only: new scale labels shown under the rating control (up to 5); pass null or [] to remove the labels. Ignored for other question types.
`formId`	Yes	The form ID the question belongs to
`aiMatch`	No	FillBlank AI grading config (knowledge_quiz scene only). Pass an object to enable AI matching (requires the question to have correctAnswer + score > 0); pass null to turn it off and revert to exact-match grading. Omit to leave the existing grading mode untouched.
`choices`	No	Replace ALL choices of a choice-based question (SingleCheck / MultiCheck / DropDown / Ordering / Cascade; rejected for other types). To keep an existing choice's identity (so past answers still match it) pass its current code from get_form; entries without a code get a new auto-generated code. knowledge_quiz scene: if the existing correctAnswer references a code missing from the new choices, pass a new correctAnswer in the same call. scored_quiz scene: set choices[i].score to rebuild Option Scoring (required if the question currently has Option Scoring). outcome_quiz scene: every choice must carry an outcomes vote list (use [] for a neutral choice).
`content`	No	Statement block only: the new body text, which is the whole block. Same rich-text rules as description. It cannot be emptied — delete_question the block if you no longer want it. This field also accepts an inline image: put an <img src="..."> in it, where src is a direct image URL that renders in <img src> (a page URL that merely contains an image does not work). Use finalize_image_upload to host an image yourself, or a direct URL the user supplied. Never invent an image URL — omit the image instead of risking a broken one.
`explain`	No	New answer explanation (the question's "answer explanation" field, not the question note); pass an empty string to clear. Same rich-text rules as description.
`required`	No	Whether the question is required
`precision`	No	DateField / TimeField only: new picker precision. DateField accepts year \| month \| day \| hour \| minute; TimeField accepts only minute \| second. Ignored for other question types.
`trueLabel`	No	TrueFalse only: new custom display text for the "true" option; pass an empty string to clear and fall back to the localized default. Ignored for other question types.
`falseLabel`	No	TrueFalse only: new custom display text for the "false" option; pass an empty string to clear and fall back to the localized default. Ignored for other question types.
`collectOnly`	No	scored_quiz scene only, for SingleCheck / MultiCheck / DropDown / Cascade / TrueFalse / Rate: true = collect the answer as data without scoring it (plain radio / checkbox display, no score, not referenceable by formulas); false = score it again with its existing Option Scoring. Turning it on is rejected while report.formula or a dimension formula still references this question — remove the reference first.
`description`	No	New question note; pass an empty string to clear. This field also accepts an inline image: put an <img src="..."> in it, where src is a direct image URL that renders in <img src> (a page URL that merely contains an image does not work). Use finalize_image_upload to host an image yourself, or a direct URL the user supplied. Never invent an image URL — omit the image instead of risking a broken one.
`correctAnswer`	No	New correct answer; the shape follows the question type — see the anyOf branches. Choices are referenced by label or code (use the code when the same label repeats), and they must exist in the question's current choices, or in the `choices` replacement passed in this same call. NumberField answers must stay typeable within min / max and decimalPlaces. Rejected for DateField / TimeField / Rate, and in the scored_quiz / outcome_quiz scenes.
`decimalPlaces`	No	NumberField only: new number of decimal places allowed (0 = integers only); pass null to reset to the default 0. Ignored for other question types.

TDQS

A4.8/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations declare destructiveHint=true but say nothing about blast radius; the description supplies it — choices 'replaces ALL choices', Swiper items 'replace ALL slides' with fresh ids that invalidate existing translations, and Statement/Swiper reject all question keys. It also discloses cross-scene rejection rules that annotations cannot express.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with purpose and the changeable-key list, then the exclusions and display-block rules. Dense and mostly earning its place, though the field enumeration ('name / description / explain / required / score / ...') duplicates what the schema repeats more precisely, so a little trimming is possible.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 21-parameter mutation tool this covers the risky parts: destructive replacement semantics, per-type and per-scene rejections, the delete+recreate fallback, and display-block quirks. An output schema exists, so return values correctly need no explanation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% so the schema already carries per-field meaning, but the description still adds value the schema cannot: the authoritative list of changeable vs immutable attributes, that precision applies to DateField/TimeField, words to Rate, and how choices rebuild Option Scoring or outcome votes per scene.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Names a specific verb and resource ('Update a single question of an existing form, located by code') and immediately enumerates the mutable fields, which separates it from add_question, insert_question and delete_question without the agent needing to open any schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly states when the tool cannot be used and routes to the alternative ('NOT changeable — delete_question then add_question instead'), and adds scene-level conditions (scored_quiz / outcome_quiz reject top-level score / correctAnswer / aiMatch; DateField/TimeField/Rate reject scoring keys). This is genuine when/when-not guidance, not implied usage.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
