Hark's responses
Reddit doesn't load comment threads in fetch, so here's the study claims vs. how they're framed in titles. Each one shows the gap between what the paper actually found and what the poster's headline suggests.
### Top 10 posts on r/science this past week · Study claims vs. Reddit framing
| # | Topic | Study claim | Reddit framing |
|---|---|---|---|
| 1 | Sleep/insomnia | Continuous slow rocking during sleep reduced awakenings and improved sleep quality; small sample | Titled as a "new way to treat insomnia" — the study is a small pilot, not a treatment trial |
| 2 | Alopecia/immunology | JAK-inhibitor arthritis drug produced substantial hair regrowth, up to full regrowth in some patients | "Up to 100%" is a best-case subset, presented as the headline result |
| 3 | Aerosols/hygiene | Flushing sends aerosols into the breathing zone, staying airborne 20+ seconds; authors recommend closing the lid | Lab aerosol measurement; no infection outcomes were measured |
| 4 | Materials/construction | Concrete made with treated human waste tested up to 42% stronger than conventional concrete | Lab-scale strength result, framed as a waste-and-emissions solution |
| 5 | Endocrinology | Visceral abdominal fat predicted low testosterone better than age did | The title's leap to Ozempic/Wegovy as an alternative to TRT is inference, not a tested comparison |
| 6 | Out-of-body experiences | Participants identified hidden objects at chance level; two later made unprompted remarks about researchers' locations | The formal result was null; the "strange twist" is anecdote the write-up itself flags as uncontrolled |
| 7 | Neuroscience/sleep | Pink-noise bursts during sleep boosted slow waves and increased CSF flow that clears brain waste | "More restorative sleep" is the proposed implication, not a measured outcome |
| 8 | Cancer epidemiology | UK data links habitually very hot drinks to higher oesophageal cancer risk | Observational and about temperature, not coffee or tea themselves |
| 9 | Addiction/neuroscience | Brain energy metabolism rebounds within weeks of stopping heavy drinking | Recovery of one metabolic measure, not of cognition broadly |
| 10 | Clinical case report | A 16-year-old had a hair bezoar obstructing stomach and small intestine, removed surgically | A single case report, so nothing generalizable despite the dramatic title |

The pattern: Reddit titles often pull the best-case result or a proposed implication and run with it as the headline, while the actual paper's scope or findings were narrower.
Fail
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.
Although there are only two prose bubbles, the second merely repeats the first bubble's general takeaway instead of adding a necessary separate detail.
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 final bubble repeats the opening claim that Reddit framing overstates or broadens the underlying study findings.
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 table has a two-sentence, roughly 32-word lead-in and a roughly 27-word takeaway, exceeding the one-sentence and 20-word limits.
answer_before_background
FailAdvisoryApplies when: Hark provides an answer or outcome with supporting background.
Requirement: Give the answer or outcome before the background detail.
The response presents the fetch limitation and framing explanation before the requested ten-item result.
avoid_routine_tool_narration
FailAdvisoryApplies when: Hark describes its research or routine tool use.
Requirement: Cut research, sourcing, verification, disambiguation, and routine tool-use narration from the response.
The opening explicitly narrates fetch behavior: “Reddit doesn't load comment threads in fetch.”
avoid_repeated_conclusions
FailAdvisoryApplies 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 conclusion about titles exceeding the studies' actual scope appears in both the opening and closing prose bubbles.
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 summary is delivered as a table plus prose and links rather than in one 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 ranked source structure is preserved, but it is not rendered 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 table rather than short numbered lines inside a document bubble.
present_partial_result_before_blocker_detail
FailAdvisoryApplies when: Hark has a useful partial result and also reports a blocker.
Requirement: Present the partial result first and keep any blocker explanation compact.
The useful ten-item partial result follows the blocker explanation instead of preceding it.
avoid_internal_error_details
FailAdvisoryApplies when: Hark reports a blocker to a user who is not debugging Hark.
Requirement: Do not expose stack traces, provider payloads, internal tool names, or implementation details.
The blocker explanation exposes the response mechanism by referring directly to “fetch.”
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 four-column table contains long claim and framing text, making it unnecessarily wide for a narrow screen.
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 opening uses two sentences, and the closing bubble summarizes the table's overall pattern rather than adding only a brief contextual caveat.
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 title, but no observable “Excel Spreadsheet” subtitle.
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 summarizes ten ranked posts, names each topic, and separates the study claim from Reddit framing in distinct columns.
preserve_draft_substance
PassAdvisoryApplies 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 preserves the ten items, core claims, qualifications, framing distinctions, and access caveat from the draft.
preserve_factual_spans
PassAdvisoryApplies 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.
Names, quantities, timing, claims, and URLs retained in the response preserve their values and scope.
avoid_invented_content
PassAdvisoryApplies 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 delivered content is drawn from the draft; no new option, commitment, or suggestion was added.
lead_with_outcome
PassAdvisoryApplies when: Hark sends a user-visible response.
Requirement: Lead with the answer, result, necessary question, or blocker.
The response begins with the material access limitation and immediately explains what result can still be provided.
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 prose is direct and compact, and the table entries use concise phrasing.
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 specific figures and outcomes such as 20 seconds, 42%, chance-level performance, and the participant's age.
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 explanations distinguish claims from 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.
The response starts with a substantive limitation rather than praise, acknowledgment, or an offer.
use_structure_only_when_helpful
PassAdvisoryApplies 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 ten comparable posts are presented in a table, and their URLs are grouped separately.
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 response uses precise terms such as JAK inhibitor, visceral fat, CSF flow, oesophageal cancer, and hair bezoar without unnecessary jargon.
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 neutral, direct register without slang or swagger.
keep_one_thought_per_bubble
PassAdvisoryApplies 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.
Each prose bubble centers on one thought: the access caveat and the overall framing pattern.
keep_prose_bubbles_compact
PassAdvisoryApplies 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.
Both prose bubbles remain below 40 words.
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 uses capitalization and ends every sentence with a period.
avoid_prose_markup
PassAdvisoryApplies 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 plain-prose bubbles contain no lists, headers, Markdown, emoji, or em-dash punctuation.
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 contains one Reddit post and its linked study or report.
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, and Reddit-framing fields.
keep_comparable_detail
PassAdvisoryApplies 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 ten commissioned items retain a topic, claim, and framing assessment, with relevant qualifications kept in their rows.
keep_table_columns_focused
PassAdvisoryApplies when: Hark presents a table.
Requirement: Keep columns focused on the user's decision or question.
The four columns directly support the requested ranking and claim-versus-commentary distinction.
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 rank 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 together in one table.
group_related_links
PassAdvisoryApplies 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.
All ten related source URLs are grouped together, one per line, in a single bubble.
preserve_link_urls
PassAdvisoryApplies 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 source URLs are written in their exact full forms rather than shortened to domains.
avoid_request_restatement
PassAdvisoryApplies 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 unnecessarily restate the request; the table title serves as useful structural context.
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.
The user commissioned ten summaries, and the response includes all ten with the requested distinctions while keeping each entry compact.
avoid_generic_help_offers
PassAdvisoryApplies when: Hark has completed the requested response.
Requirement: Do not append a generic offer of further help.
The delivered response does not append an offer of further help.
follow_summary_instructions
PassAdvisoryApplies 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 summary covers ten posts, includes each topic, and explicitly distinguishes study claims from Reddit framing.
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 keeps the fetched weekly ranking order and numbers the entries 1 through 10.
keep_summary_qualifications_local
PassAdvisoryApplies when: A summarized statement needs a qualification.
Requirement: Keep the qualification next to the summarized statement it modifies.
Qualifications such as small sample, observational design, null formal result, and single-case status are placed in the corresponding rows.
state_blocker_and_impact
PassAdvisoryApplies 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.
The response states that comment threads do not load through fetch and explains that only study claims and title framing can therefore be compared.
avoid_repeated_apology
PassAdvisoryApplies when: Hark reports a blocker or failure.
Requirement: Avoid repeated apologies and generic failure language.
The blocker is reported without any repeated apology or generic failure language.
avoid_markdown_in_prose
PassAdvisoryApplies 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 plain-prose bubbles contain no Markdown; the structured table and links are isolated in separate bubbles.
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 response.
isolate_rich_content
PassAdvisoryApplies 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 each placed in their own bubbles, separate from prose.
tag_every_bubble
PassAdvisoryApplies 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.
Observable delivery separates plain text, the table, and the grouped links into matching bubble forms.
limit_rich_bubbles
PassAdvisoryApplies when: Hark sends rich content.
Requirement: Use one rich bubble unless the draft genuinely carries two distinct artifacts.
The response uses two distinct rich artifacts: the comparison table and the grouped source-link set.
Not applicable
preserve_instruction_direction
Not applicableAdvisoryApplies 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.
Not applicable. The response does not shorten or merge a draft instruction telling the user what to do.
avoid_unwarranted_social_language
Not applicableAdvisoryApplies 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 response contains no praise, reassurance, or apology.
ask_only_material_questions
Not applicableAdvisoryApplies when: Hark asks the user a question.
Requirement: Ask only when the draft asks a material question. Do not append a reflex question after completing the response.
Not applicable. The delivered response asks no question.
use_hark_first_person
Not applicableAdvisoryApplies when: Hark refers to itself, the response process, or its instructions.
Requirement: Speak as Hark in the first person. Never mention the draft, rewrite, editor, prompt, or response rules.
Not applicable. The response does not refer to Hark or itself.
use_hearer_oriented_grammar
Not applicableAdvisoryApplies 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.
Not applicable. No relevant possessive, imperative, or statement about Hark's wellbeing occurs.
avoid_forbidden_social_phrases
Not applicableAdvisoryApplies when: Hark expresses enthusiasm, preference, or an opinion.
Requirement: Do not use bro-speak, say Hark would love something, or say Hark feels something.
Not applicable. The response expresses no enthusiasm, preference, or personal opinion.
avoid_delivery_pointers
Not applicableAdvisoryApplies 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.
Not applicable. The response does not direct the user above, below, or to a saved location.
include_recommendation_links
Not applicableAdvisoryApplies 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.
Not applicable. The table is a summary of posts, not a set of options or recommendations.
isolate_single_links
Not applicableAdvisoryApplies 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 ten URLs rather than exactly one.
make_progress_updates_material
Not applicableAdvisoryApplies 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 contains no progress update.
use_default_summary_length
Not applicableAdvisoryApplies 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.
Not applicable. The user specified a ten-item summary with required fields, so the unconstrained default-summary condition does not apply.
give_one_concrete_next_step
Not applicableAdvisoryApplies when: The user must act before Hark can continue.
Requirement: State one concrete next step only when the draft offers it.
Not applicable. The delivered response does not require the user to act before Hark can continue.
omit_running_task_updates
Not applicableAdvisoryApplies 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 evidence does not say the task remained running when the response was delivered.
preserve_code_exactly
Not applicableAdvisoryApplies 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.
preserve_document_exactly
Not applicableAdvisoryApplies 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.
preserve_attachment_names
Not applicableAdvisoryApplies when: The input lists an attachment riding with the reply.
Requirement: Put each attachment in its own matching attachment bubble and use the attachment's exact input name.
Not applicable. No attachment is listed in the input.
