Hark's responses
### r/science top posts, past week · Top 10 posts
| # | Topic | Study claim | Reddit headline | Note |
|---|---|---|---|---|
| 1 | Sleep / insomnia | Continuous slow rocking during sleep reduced nighttime awakenings and improved sleep quality | "Could offer a new way to treat insomnia" | Small sample, preliminary |
| 2 | Alopecia / JAK inhibitors | Arthritis drug produced substantial hair regrowth in severe alopecia areata patients | "Up to 100%" | Best-case responder, not average |
| 3 | Toilet plume aerosols | Flushing sends aerosols into breathing zone; they stay airborne at least 20 seconds | Headline faithful | Measures aerosol transport, not infection risk |
| 4 | Materials / construction | Concrete made with treated human waste tested up to 42% stronger than conventional mixes | Headline implies real-world application | Lab-scale samples; environmental benefit is researchers' projection |
| 5 | Testosterone / visceral fat | Visceral abdominal fat predicts low testosterone better than age does | Implies Ozempic/Wegovy as treatment | Inference about implications, not tested intervention |
| 6 | Out-of-body experiences | Formal test was null: object identification no better than chance | "Something strange happened" | Anecdotal observation, not the result |
| 7 | Pink noise and sleep | Pink-noise bursts during sleep boosted slow waves and cerebrospinal fluid flow | "Washes away toxic waste" | Glymphatic hypothesis; "more restorative" is flagged potential |
| 8 | Hot drinks and cancer | UK data links habitually very hot tea/coffee to higher oesophageal cancer risk | Temperature equals cause | Observational, so association not proof |
| 9 | Alcohol recovery / brain metabolism | Brain's energy metabolism rebounds within weeks of stopping heavy drinking | "Recovers" | Refers to one metabolic measure, not full cognitive recovery |
| 10 | Rapunzel syndrome case report | 16-year-old needed surgery for hairball obstructing stomach and small intestine | Striking detail in title | Single case report, no generalizable finding |
Study claim is what the source actually tested or found. Reddit headline is the submitted title, which often overstates or reframes the finding. The note flags what matters: small sample size, best-case reporting, observational data, preliminary stage, or extrapolation beyond what was tested.
Health and sleep dominated the week. Three of the ten were submitted by u/mvea.
Fail
preserve_draft_substance
FailAdvisoryApplies 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 table drops source and post links and removes some substantive details, including the toilet-lid recommendation.
preserve_factual_spans
FailAdvisoryApplies 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.
Several factual spans are preserved, but row 8 changes the Reddit headline into the stronger statement “Temperature equals cause,” which was not its wording or scope.
preserve_instruction_direction
FailAdvisoryApplies 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 draft's toilet-aerosol sentence included the instruction to close the lid, but the delivered row retains the findings while cutting that instruction.
avoid_invented_content
FailAdvisoryApplies 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 response invents headline characterizations such as “Temperature equals cause,” which neither the fetched headline nor the draft states.
use_structure_only_when_helpful
FailAdvisoryApplies 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.
A table is appropriate, but it is rendered as Markdown rather than as the required table bubble.
limit_prose_bubbles
FailAdvisoryApplies 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.
The reply uses three assistant messages, including an avoidable explanatory bubble that narrates the table rather than carrying one essential detail.
keep_one_thought_per_bubble
FailAdvisoryApplies 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 second bubble combines definitions of three table fields and multiple caveat categories rather than one compact thought.
keep_prose_bubbles_compact
FailAdvisoryApplies 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.
The second prose bubble is about 43 words, exceeding the 40-word limit.
avoid_prose_markup
FailAdvisoryApplies 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 first assistant message uses a Markdown header and Markdown table syntax.
avoid_duplicate_content
FailAdvisoryApplies 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.
The second bubble repeats caveat categories already represented in the table, including small samples, observational data, preliminary findings, and extrapolation.
keep_comparable_detail
FailAdvisoryApplies 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.
The delivered rows omit facts and all source and Reddit-post destinations supplied for each item in the draft.
include_recommendation_links
FailAdvisoryApplies 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.
The draft supplied a source link and Reddit-post link for each row, but the delivered table has no link columns.
keep_deliverable_companions_brief
FailAdvisoryApplies 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 response places two prose messages after the table, and the first exceeds 20 words.
avoid_request_restatement
FailAdvisoryApplies 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 heading restates the subreddit, time period, and requested count without resolving ambiguity or confirming a necessary detail.
compress_summary
FailAdvisoryApplies when: Hark provides a summary.
Requirement: Put the summary in one document bubble and keep it materially shorter than the source.
The result is materially compressed, but it is not delivered in the required document bubble.
follow_summary_instructions
FailAdvisoryApplies 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 requested count and focus are followed, but the summary is not delivered as the required document bubble.
preserve_summary_skeleton
FailAdvisoryApplies when: Hark provides a summary.
Requirement: Keep the source's own skeleton while making each section or act a short numbered line.
The feed order and numbering are retained, but the summary is not formatted as short numbered lines in a document bubble.
use_summary_numbered_lines
FailAdvisoryApplies when: Hark formats a structured-source summary.
Requirement: Use short numbered lines inside the document bubble instead of flat prose bubbles.
The structured summary uses a Markdown table rather than numbered lines inside a document bubble.
avoid_markdown_in_prose
FailAdvisoryApplies 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 uses Markdown heading and table syntax instead of a tagged table bubble.
keep_narrow_screens_readable
FailAdvisoryApplies when: Hark presents structured content in web chat.
Requirement: Keep the response readable on a narrow screen and avoid unnecessarily wide tables.
The five-column table contains long claim and caveat text, making it unnecessarily wide for narrow screens.
isolate_rich_content
FailAdvisoryApplies 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 is embedded as Markdown in the same message as a heading rather than isolated in a correctly tagged table bubble.
keep_card_companions_contextual
FailAdvisoryApplies 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 long second bubble narrates the table's column meanings and repeats its caveat categories, and a second companion bubble follows it.
tag_every_bubble
FailAdvisoryApplies 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 observed assistant messages have no matching text or table bubble tags, and the table appears as Markdown.
provide_rich_metadata
FailAdvisoryApplies 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 pipe rows and a heading, but it lacks the required Excel Spreadsheet subtitle and proper table-bubble metadata.
Pass
follow_explicit_style_instructions
PassAdvisoryApplies 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 delivers ten ranked summaries and separates each study claim from Reddit framing and caveats.
lead_with_outcome
PassAdvisoryApplies when: Hark sends a user-visible response.
Requirement: Lead with the answer, result, necessary question, or blocker.
The response opens directly with the requested ranked result.
use_direct_short_sentences
PassAdvisoryApplies when: Hark sends a user-visible prose response.
Requirement: Use direct, short sentences and the shortest phrasing that preserves the full meaning.
The table uses concise claim and caveat phrasing, and the surrounding prose is direct.
prefer_specific_details
PassAdvisoryApplies when: Specific names, dates, quantities, or outcomes are available.
Requirement: Use the specific details instead of vague adjectives or descriptions.
The response retains useful specifics such as 20 seconds, 42%, the 16-year-old patient, and the top-ten ranking.
avoid_condescending_explanations
PassAdvisoryApplies when: Hark explains information to the user.
Requirement: Explain the information without talking down to the user or belaboring basic points.
The explanation distinguishes source findings from Reddit framing without talking down to the user.
avoid_throat_clearing
PassAdvisoryApplies 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.
There is no praise, generic acknowledgment, offer, or preview before the result.
use_plain_precise_language
PassAdvisoryApplies 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 wording is generally plain and uses relevant terms such as visceral fat, cerebrospinal fluid, and oesophageal cancer.
match_register_to_stakes
PassAdvisoryApplies when: Hark responds about a serious, painful, or high-stakes subject.
Requirement: Stay short and direct while dropping slang and swagger.
Medical and health topics are described in a restrained, professional register without slang or swagger.
use_hearer_oriented_grammar
PassAdvisoryApplies 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.
No awkward self-oriented possessives or incorrect wellbeing constructions appear.
punctuate_sentences
PassAdvisoryApplies when: Hark sends a plain-prose bubble.
Requirement: Use proper capitalization and end every sentence with a period or question mark.
The prose sentences use capitalization and terminal punctuation.
avoid_delivery_pointers
PassAdvisoryApplies 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 delivers the summaries directly and does not point to another message or location.
choose_collection_format_for_comparison
PassAdvisoryApplies 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.
The ten posts share common fields and are presented in one comparison table.
keep_one_entity_per_item
PassAdvisoryApplies when: Hark presents comparable entities or occurrences in a table.
Requirement: Put one comparable entity or occurrence in each row.
Each table row represents one Reddit post and linked study.
use_consistent_collection_schema
PassAdvisoryApplies when: Hark presents multiple comparable items.
Requirement: Expose the same fields with the same meanings for every comparable item.
Every row uses the same rank, topic, study claim, Reddit headline, and note fields.
keep_table_columns_focused
PassAdvisoryApplies when: Hark presents a table.
Requirement: Keep columns focused on the user's decision or question.
The columns directly support the requested comparison between study claims and Reddit framing.
include_ranking_column
PassAdvisoryApplies when: The user asks for the cheapest, fastest, lightest, or another ranked comparison.
Requirement: Include the fact used for ranking as a table column, even when every row ties.
The table includes a numbered ranking column from 1 through 10.
keep_every_commissioned_item
PassAdvisoryApplies 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.
All ten requested posts appear in one table.
answer_before_background
PassAdvisoryApplies when: Hark provides an answer or outcome with supporting background.
Requirement: Give the answer or outcome before the background detail.
The ranked summaries appear before the explanatory background and concluding observation.
avoid_routine_tool_narration
PassAdvisoryApplies when: Hark describes its research or routine tool use.
Requirement: Cut research, sourcing, verification, disambiguation, and routine tool-use narration from the response.
The delivered response does not narrate web fetching, sourcing steps, or tool activity.
avoid_repeated_conclusions

Requirement: State the conclusion once unless repetition is necessary for clarity.
The final observation about dominant topics and u/mvea appears only once.
match_detail_to_request
PassAdvisoryApplies 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 ten items, the response appropriately retains all ten with concise comparative detail.
avoid_generic_help_offers
PassAdvisoryApplies when: Hark has completed the requested response.
Requirement: Do not append a generic offer of further help.
No generic offer of further help is appended.
preserve_summary_order
PassAdvisoryApplies when: Hark summarizes a source with sections or acts.
Requirement: Preserve the source's section or act order and do not drop one.
The response follows the fetched feed order, using the nine first-page posts and then the Rapunzel syndrome post.
keep_summary_qualifications_local
PassAdvisoryApplies when: A summarized statement needs a qualification.
Requirement: Keep the qualification next to the summarized statement it modifies.
Each qualification appears in the same row as the study claim it modifies.
include_result_in_message
PassAdvisoryApplies 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 complete ten-item result is included directly in the assistant messages.
limit_rich_bubbles

isolate_single_links
Not applicableAdvisoryApplies when: Hark shares exactly one URL that is worth opening.

Not applicable. The delivered response shares no URL.
group_related_links
Not applicableAdvisoryApplies 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.
Not applicable. The delivered response shares no URLs.
preserve_link_urls

Not applicable. The delivered response contains no progress update.
use_default_summary_length

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.
Not applicable. The user specified a ten-item summary, so the default-length condition does not apply.
state_blocker_and_impact
Not applicableAdvisoryApplies when: Hark reports that it cannot complete all or part of the task.
