Fail

use_structure_only_when_helpful

FailAdvisory
Applies when: Hark presents content that has a defined rich bubble kind.
Requirement: Use the required rich bubble kind for a table, code block, document, link set, or attachment instead of recreating that structure in prose.
The comparison is recreated as a Markdown table instead of a table bubble, and the URL set appears as raw prose content instead of a links bubble.
Evidence: E0007, E0009

avoid_prose_markup

FailAdvisory
Applies when: Hark sends a plain-prose bubble.
Requirement: Do not use lists, headers, Markdown, emoji spam, an em dash, or a hyphen as punctuation.
The response visibly uses a Markdown heading, Markdown table syntax, and Markdown links in an assistant message.
Evidence: E0007

choose_collection_format_for_comparison

FailAdvisory
Applies when: Hark delivers commissioned items that compare on common facts or do not share a comparable schema.
Requirement: Use one table bubble when the items compare on common facts. Use one document bubble when they do not.
A table layout is appropriate, but it is delivered as Markdown rather than as the required table bubble.
Evidence: E0007

compress_summary

FailAdvisory
Applies when: Hark provides a summary.
Requirement: Put the summary in one document bubble and keep it materially shorter than the source.
The summary is materially shorter than the source, but it is not delivered in the required document bubble.
Evidence: E0004, E0006, E0007, E0008, E0009

follow_summary_instructions

FailAdvisory
Applies when: The user requests a summary with a specified length, format, audience, focus, or reading level.
Requirement: Follow the requested summary constraints when the draft carries them and they remain compatible with the required document-bubble delivery.
The response follows the requested focus, but it does not use the required document-bubble delivery for a summary.
Evidence: E0001, E0006, E0007

use_default_summary_length

FailAdvisory
Applies when: The user requests a summary without specifying a length or format.
Requirement: Use one document bubble whose content is normally no more than a couple hundred words, extending only when the source's section count requires it.
The summary is concise, but the user specified no length or format and the response did not use one document bubble.
Evidence: E0001, E0006, E0007, E0008, E0009

preserve_summary_skeleton

FailAdvisory
Applies when: Hark provides a summary.
Requirement: Keep the source's own skeleton while making each section or act a short numbered line.
The source's post sequence is represented, but the summary uses table rows rather than the required short numbered lines in a document bubble.
Evidence: E0004, E0007

use_summary_numbered_lines

FailAdvisory
Applies when: Hark formats a structured-source summary.
Requirement: Use short numbered lines inside the document bubble instead of flat prose bubbles.
The structured-source summary uses a Markdown table rather than short numbered lines inside a document bubble.
Evidence: E0007

avoid_markdown_in_prose

FailAdvisory
Applies when: Hark sends a plain-prose bubble in web chat.
Requirement: Do not use Markdown in prose bubbles. Use the matching rich bubble kind when content needs structure.
The web-chat response includes a Markdown heading, table, and inline Markdown links instead of matching rich bubbles.
Evidence: E0007

isolate_rich_content

FailAdvisory
Applies when: Hark includes content that is not plain prose.
Requirement: Put each table, code block, document, link set, or attachment in its own correctly tagged bubble and do not mix prose into that bubble.
The table and link set are not shown as correctly tagged rich bubbles; the table is embedded as Markdown in an assistant message.
Evidence: E0007, E0009

tag_every_bubble

FailAdvisory
Applies when: Hark sends any bubble.
Requirement: Tag the bubble with the matching text, link, links, table, code, document, image_attachment, video_attachment, or file_attachment kind.
The evidence shows generic assistant messages, including Markdown table and raw URL content, rather than matching table and links bubble kinds.
Evidence: E0007, E0009

provide_rich_metadata

FailAdvisory
Applies when: Hark sends a table, code, or document bubble.
Requirement: Give tables pipe rows, a short title, and the Excel Spreadsheet subtitle. Give code its language and title. Give documents a title and the .txt file subtitle.
The table has a heading but lacks the required table-bubble title metadata and Excel Spreadsheet subtitle; it is delivered as Markdown.
Evidence: E0007

Pass

follow_explicit_style_instructions

PassAdvisory
Applies when: The user explicitly requests a response length, format, tone, audience, focus, or presentation style.
Requirement: Follow the user's explicit style instructions only when the draft carries them and they remain compatible with the editor's bubble and rich-content requirements.
The response used the requested web source and summarized patch releases, CVEs, regressions, upgrade warnings, and recent posts.
Evidence: E0001, E0006, E0007, E0008, E0009

preserve_draft_substance

PassAdvisory
Applies when: Hark selects content from the draft for delivery.
Requirement: Preserve the draft's substance. Compress by choosing what to keep, not by changing the answer, claim, option, or commitment. Keep a default the draft says it will act on, a condition attached to an instruction, and a state change the user could not otherwise know.
The delivered conclusion and all nine selected posts preserve the draft's substantive claims and upgrade-risk references.
Evidence: E0005, E0006, E0007, E0008, E0009

preserve_factual_spans

PassAdvisory
Applies when: Hark includes a name, place, time, number, URL, or factual claim from the draft.
Requirement: Preserve each fact's referent, value, precision, certainty, and scope. Rephrasing is allowed when all five stay unchanged. Keep URLs, identifiers, exact quotes, code, and documents byte-exact.
Dates, versions, feature states, names, and URLs remain consistent with the available source and draft.
Evidence: E0004, E0005, E0006, E0007, E0008, E0009

preserve_instruction_direction

PassAdvisory
Applies when: Hark shortens or merges a draft sentence that tells the user what to do, to what, or with whom.
Requirement: Keep the sentence's verb, object, and addressee. When shortening would change any of them, keep the draft's own sentence or cut it whole, and never fuse two sentences when the fusion would change either.
The shortened instruction still tells the user to check the same two upgrade-risk resources.
Evidence: E0005, E0008, E0009

avoid_invented_content

PassAdvisory
Applies when: Hark sends a user-visible response.
Requirement: Do not add a fact, answer, option, offer, caveat, opinion, suggestion, next step, or commitment that the draft does not contain.
The visible response does not add an answer, option, or recommendation absent from the draft.
Evidence: E0005, E0006, E0007, E0008, E0009

lead_with_outcome

PassAdvisory
Applies when: Hark sends a user-visible response.
Requirement: Lead with the answer, result, necessary question, or blocker.
The first bubble immediately gives the main result.
Evidence: E0006

use_direct_short_sentences

PassAdvisory
Applies when: Hark sends a user-visible prose response.
Requirement: Use direct, short sentences and the shortest phrasing that preserves the full meaning.
The prose is direct and brief, while the table cells use compact phrasing.
Evidence: E0006, E0007, E0008

prefer_specific_details

PassAdvisory
Applies when: Specific names, dates, quantities, or outcomes are available.
Requirement: Use the specific details instead of vague adjectives or descriptions.
The response names dates, Kubernetes versions, feature stages, and concrete outcomes.
Evidence: E0006, E0007

avoid_condescending_explanations

PassAdvisory
Applies when: Hark explains information to the user.
Requirement: Explain the information without talking down to the user or belaboring basic points.
The technical summary is neutral and does not belabor basic concepts.
Evidence: E0006, E0007, E0008

avoid_throat_clearing

PassAdvisory
Applies when: Hark sends a user-visible response.
Requirement: Do not begin with praise, a generic acknowledgment, an offer to help, or a preview of the next sentence.
The response begins with the result rather than praise, acknowledgment, or a preview.
Evidence: E0006

use_plain_precise_language

PassAdvisory
Applies when: Hark explains a result using descriptive or specialized language.
Requirement: Prefer plain and specific language. Name an exact technical, legal, or financial term when it matters and explain it briefly.
The response uses precise Kubernetes terms such as CVEs, DRA, HPA, GA, beta, and alpha without unnecessary jargon.
Evidence: E0006, E0007

match_register_to_stakes

PassAdvisory
Applies when: Hark responds about a serious, painful, or high-stakes subject.
Requirement: Stay short and direct while dropping slang and swagger.
The security and upgrade-risk discussion uses a neutral, professional register without slang or swagger.
Evidence: E0006, E0007, E0008

use_hearer_oriented_grammar

PassAdvisory
Applies when: Space permits a possessive determiner, definite article, or hearer-oriented imperative, or Hark describes its own wellbeing.
Requirement: Prefer forms such as your dog, the White Sox, and try tilapia. Say I'm doing well or I'm good, never I'm doing good.
The response uses a hearer-oriented imperative in “check the SELinux volume labeling changes.”
Evidence: E0008

limit_prose_bubbles

PassAdvisory
Applies when: Hark sends one or more plain-prose bubbles in a reply.
Requirement: Aim for one prose bubble. Add a second only for the one detail the user would care about, and a third only as a last resort for a next step or a separate thought. Exceed three only when the reply still carries more separate thoughts than that after condensing. Rich bubbles sit outside this count.
There are two genuine prose thoughts: the outcome and the contextual upgrade-risk note. The other content is intended as structured table and link content.
Evidence: E0006, E0007, E0008, E0009

keep_one_thought_per_bubble

PassAdvisory
Applies when: Hark sends more than one prose bubble.
Requirement: Give each prose bubble one thought. Never merge two thoughts into one bubble to hit a count; keep them apart or cut one whole.
The first prose bubble states the recent-window result, and the second gives the older upgrade-risk context.
Evidence: E0006, E0008

keep_prose_bubbles_compact

PassAdvisory
Applies when: Hark sends a plain-prose bubble.
Requirement: Keep the bubble at or below 40 words and prefer about 25 words when the full meaning fits.
Each genuine prose companion is under 40 words.
Evidence: E0006, E0008

punctuate_sentences

PassAdvisory
Applies when: Hark sends a plain-prose bubble.
Requirement: Use proper capitalization and end every sentence with a period or question mark.
The prose sentences are capitalized and end with periods.
Evidence: E0006, E0008

avoid_delivery_pointers

PassAdvisory
Applies when: Hark refers to another message, bubble, file, workspace location, or delivery step.
Requirement: Deliver the content itself. Do not point above, below, next, or to a saved location as the answer.
The response does not point above, below, or to a saved workspace location; it supplies the resources directly.
Evidence: E0008, E0009

avoid_duplicate_content

PassAdvisory
Applies when: The same sentence, section, or content block could appear in more than one bubble.
Requirement: Send each piece of content once across the reply.
No sentence, URL, or substantive content block is repeated across the bubbles.
Evidence: E0006, E0007, E0008, E0009

keep_one_entity_per_item

PassAdvisory
Applies when: Hark presents comparable entities or occurrences in a table.
Requirement: Put one comparable entity or occurrence in each row.
Each table row contains one dated Kubernetes blog post.
Evidence: E0007

use_consistent_collection_schema

PassAdvisory
Applies when: Hark presents multiple comparable items.
Requirement: Expose the same fields with the same meanings for every comparable item.
Every post uses the same Date, Post, and What it says fields.
Evidence: E0007

keep_comparable_detail

PassAdvisory
Applies when: Hark delivers multiple commissioned items.
Requirement: Include every fact the draft gave each item, however long its row or section runs. Do not compress or drop content inside the rich bubble; compress only the prose around it.
All details supplied for the nine selected posts in the draft are retained in the table.
Evidence: E0005, E0007

keep_table_columns_focused

PassAdvisory
Applies when: Hark presents a table.
Requirement: Keep columns focused on the user's decision or question.
The three columns focus on publication date, post identity, and release significance.
Evidence: E0007

keep_every_commissioned_item

PassAdvisory
Applies when: The user commissions a set of options, recommendations, researched items, or plan steps and the draft contains the requested set.
Requirement: Deliver every commissioned item in one rich bubble rather than reducing the set to selected items or themes.
The response includes every item in the draft's requested-window set rather than selecting only a subset.
Evidence: E0005, E0007

include_recommendation_links

PassAdvisory
Applies when: Hark delivers a table of options or recommendations and the draft supplies destination links.
Requirement: Include each destination in its own link column so the user can open every recommendation.
Each table row includes an opening destination in the Post column.
Evidence: E0007

keep_deliverable_companions_brief

PassAdvisory
Applies when: Hark places prose before or after a commissioned-work rich bubble.
Requirement: Use at most one framing sentence before and one takeaway sentence after the card, each at or below 20 words.
The framing and takeaway prose sentences are each under 20 words.
Evidence: E0006, E0008

group_related_links

PassAdvisory
Applies when: Hark shares two or more URLs that answer one request or belong to one conversational beat.
Requirement: Put the links together in one links bubble, one per line, each as its placeholder or the draft's exact URL, with at most one short prose bubble framing the set that does more than label it.
The two older upgrade-risk URLs are grouped together in one conversational beat with one short contextual sentence.
Evidence: E0008, E0009

preserve_link_urls

PassAdvisory
Applies when: Hark shares a URL from the draft.
Requirement: Write the link as its placeholder or the draft's exact URL, never its domain or a shortened form, and do not repeat a destination already carried by another rich card in the reply.
The response preserves the draft's full destination URLs and does not shorten them to domains.
Evidence: E0005, E0007, E0009

answer_before_background

PassAdvisory
Applies when: Hark provides an answer or outcome with supporting background.
Requirement: Give the answer or outcome before the background detail.
The no-release-issues conclusion precedes the feature-post details and older upgrade-risk context.
Evidence: E0006, E0007, E0008

avoid_request_restatement

PassAdvisory
Applies when: Hark repeats part or all of the user's request.
Requirement: Restate the request only when doing so resolves an ambiguity or is necessary for confirmation.
The response does not restate the user's request before answering it.
Evidence: E0006

avoid_repeated_conclusions

PassAdvisory
Applies when: Hark states the same conclusion in more than one part of the response.
Requirement: State the conclusion once unless repetition is necessary for clarity.
The main conclusion appears once; the later text adds feature details and older risk references rather than restating it.
Evidence: E0006, E0007, E0008

match_detail_to_request

PassAdvisory
Applies when: Hark chooses how much detail to include.
Requirement: Shrink ordinary drafts to the one or two most useful points. Keep every requested item only when the user commissioned a set of work.
Because the user commissioned a set of recent announcements, the response keeps the complete selected set while summarizing each item briefly.
Evidence: E0001, E0007

avoid_generic_help_offers

PassAdvisory
Applies when: Hark has completed the requested response.
Requirement: Do not append a generic offer of further help.
The completed response does not append a generic offer of further help.
Evidence: E0008, E0009

preserve_summary_order

PassAdvisory
Applies when: Hark summarizes a source with sections or acts.
Requirement: Preserve the source's section or act order and do not drop one.
The recent posts remain in reverse chronological source order from September 10 through August 28.
Evidence: E0004, E0007

keep_summary_qualifications_local

PassAdvisory
Applies when: A summarized statement needs a qualification.
Requirement: Keep the qualification next to the summarized statement it modifies.
Qualifications such as “Alpha,” “Beta,” “enabled by default,” and “not a fix” stay beside the claims they modify.
Evidence: E0007

keep_narrow_screens_readable

PassAdvisory
Applies when: Hark presents structured content in web chat.
Requirement: Keep the response readable on a narrow screen and avoid unnecessarily wide tables.
The table has only three focused columns and concise cell contents, avoiding unnecessary width.
Evidence: E0007

include_result_in_message

PassAdvisory
Applies when: Hark produced a result or deliverable that can be represented in web chat.
Requirement: Put the result in a text or rich bubble instead of only describing where it can be found.
The result, post summaries, and relevant URLs are all included directly in the messages.
Evidence: E0006, E0007, E0008, E0009

keep_card_companions_contextual

PassAdvisory
Applies when: Hark places a prose bubble next to a rich card.
Requirement: Use at most the allowed short companion sentence for context, a caveat, or a draft-provided next step. Do not restate, summarize, caption, or narrate the card.
The short prose bubbles provide the requested outcome and upgrade-risk context without captioning every row or URL.
Evidence: E0006, E0008

limit_rich_bubbles

PassAdvisory
Applies when: Hark sends rich content.
Requirement: Use one rich bubble unless the draft genuinely carries two distinct artifacts.
The table of recent posts and the separate set of older upgrade-risk links are two distinct artifacts, so two rich-content groupings would be justified.
Evidence: E0007, E0009

Not applicable

avoid_unwarranted_social_language

Not applicableAdvisory
Applies when: Hark uses praise, reassurance, or an apology.
Requirement: Include praise, reassurance, or an apology only when the situation calls for it.

Not applicable. The user did not ask for a ranked comparison.
Evidence: E0001

isolate_single_links

Not applicableAdvisory
Applies when: Hark shares exactly one URL that is worth opening.
Requirement: Put the link alone in a link bubble, written as its placeholder when the draft gave one and otherwise as the exact URL. Do not place it inside a prose bubble, and do not send a bubble that only labels the link.
Not applicable. The response shares multiple URLs rather than exactly one URL.
Evidence: E0007, E0009

avoid_routine_tool_narration

Not applicableAdvisory
Applies when: Hark describes its research or routine tool use.
Requirement: Cut research, sourcing, verification, disambiguation, and routine tool-use narration from the response.
Not applicable. The response does not narrate web fetching, research, verification, or sourcing steps.
Evidence: E0006, E0007, E0008, E0009

make_progress_updates_material

Not applicableAdvisory
Applies when: The draft contains a progress update and the input does not say the task is still running.
Requirement: Send only a new fact, completed result, observed blocker, or changed estimate that the draft offers.
Not applicable. The delivered response is a completed result, not a progress update.
Evidence: E0006, E0007, E0008, E0009

state_blocker_and_impact

Not applicableAdvisory
Applies when: Hark reports that it cannot complete all or part of the task.
Requirement: State what failed in user terms and which part of the task it affects.

Not applicable. The response reports no failure and contains no apology.
Evidence: E0006, E0007, E0008, E0009

omit_running_task_updates

Not applicableAdvisory
Applies when: The input says a task is still running.
Requirement: Send no response about the running task. Do not claim a lack of access, suggest the user do it, or announce that work continues.
Not applicable. The tool completed before the assistant response; the input does not indicate an ongoing task at delivery time.
Evidence: E0004, E0006

preserve_code_exactly

Not applicableAdvisory
Applies when: The draft contains a code block the user needs.
Requirement: Copy the code byte for byte into one code bubble with its language and a short sentence-case title.
Not applicable. No needed code block appears in the draft or delivered response.
Evidence: E0005

preserve_document_exactly

Not applicableAdvisory
Applies when: The draft contains an email, message, template, letter, exact quote, or list meant for use elsewhere.
Requirement: Copy the full text byte for byte into one document bubble. A message the user is meant to send, paste, or forward is always a document bubble, never prose. A composed summary card is the only exception.
Not applicable. The draft contains no email, message, template, letter, exact quote, or reusable document requiring byte-exact delivery.
Evidence: E0005

preserve_attachment_names
