description

Iterate the FULL social/community + trusted-curator source lists in SOURCES.md (Reddit, Hacker News, YouTube curators, explainer/digest pointer blogs, Hugging Face, best-effort X/Instagram) on every daily run — every listed entry, fetched by its recorded access method, NOT a sampled subset. Social/curator is an INTAKE LANE ONLY — it can feed observation_queue (unverified) and a community-pulse note, but NEVER becomes trend evidence. Use after the lab sweep.

Community pulse — intake only, never evidence

Social tells you what people think and what is gaining traction before it reaches papers/docs, and it is often the FASTEST place to spot that something official exists (a post links a repo, a release, a paper). Social is not a primary source — but it is a discovery accelerator. This skill captures both without corroding the ledger's evidence standard.

The platform/channel/profile list lives in SOURCES.md; treat it as a seed and curate it by your own judgment — add platforms and accounts that prove useful, drop noise. Don't restrict yourself to a fixed roster.

Absolute rules (constitutional carve-out — see AGENTS.md Hard rules)

1. Social NEVER becomes trend evidence. It may only:
   • create observation_queue items, marked unverified — promotable to a trend ONLY after the claim is confirmed on a primary artifact (paper, repo, release, official doc), via the radar-source-verify skill;
   • feed the community-pulse note surfaced on the dashboard (Phase 3).
2. Never name or quote individuals in the repo. Link the thread/profile and summarise the signal ("a widely-upvoted r/LocalLLaMA thread reports X"). No handles in evidence/queue text beyond the bare URL.
3. Opened-source rule still applies: only log what you actually fetched.
4. Per-channel coverage logging (APPLIED 2026-08-29, W35 — was W34 Proposal O, cooling period held, signal persisted: the W34 coverage miss RECURRED on 08-24 when the daily collapsed the whole Phase-2 lane into a single PULSE (HN…) line, and the strategy_notes discipline note alone reverted on the first post-weekly Monday — so codify it in the loaded skill): the pulse lane's line in logs/source_rotation.md MUST enumerate EACH Phase-2 channel touched this run — HN, the Reddit sub-groups, each YouTube curator, each digest/pointer blog (tldrsec, Simon Willison, Kai Greshake, Embrace The Red), Hugging Face — BY NAME with opened or degraded: <reason>, exactly as the primary-feed lane logs each feed. NEVER collapse the lane into one HN line: a Phase-2 channel absent from the log line is a coverage lie identical to a missing primary feed (an unlogged degrade reads the same as a forgotten source). Grouping several SAME-status channels in one sub-clause is fine (Reddit / tldrsec / Willison → degraded: tvly-plan-cap) as long as each is NAMED; a bare PULSE (HN…) line is not. This makes the coverage-discipline hard rule more precise; it relaxes nothing.

Method (best-effort via Tavily, no paid APIs)

Per run, ITERATE EVERY entry in the source lists at SOURCES.md (see "## Source lists" below) — the list is the CONTRACT: execute all of it, do not "sample" a representative subset (sampling is exactly how feed-less entries get silently dropped while the easy RSS ones get done). "Light" means SHALLOW per source (read the new items' titles), NEVER skipping a source: the CHECK (fetch each entry and see what is new since the last pass) is owed EVERY run, even one minute after another pass; only the EXTRACT (follow a new item to its primary and verify) is conditional on something new. A skipped source is not "light", it is a missed lane. For each source, by category:

• Reddit: read the TOP posts of the tracked subreddits — both the technical subs AND the broad-pulse subs. Note two things, not one: (a) recurring on-axis topics, and (b) whatever is dominating a community right now, on-axis or not.
• Hacker News: read the FRONT PAGE unconditionally (the #1 story is a don't-miss), in addition to term searches.
• Trusted curators (YouTube + explainer/digest pointer blogs) — a PRIMARY DISCOVERY path, not "social noise": ITERATE EVERY entry in the SOURCES.md curator lists, one by one, with the SAME discipline as the lab sweep — not a sampled subset. For each entry, fetch by its recorded access method: its feed if it has one, else tvly extract of its index/page (exactly as the lab sweep does for feed-less NVIDIA/Meta). A feed-less entry is NEVER a reason to skip — if it has no recorded method, that is a radar-source-heal job, not a drop. Log each entry as opened OR degraded: <reason>; a listed entry absent from the coverage log is a coverage lie. For every new video/post, FOLLOW the link to the named primary and verify it (radar-source-verify); cite the primary, never the curator. This is how high-signal work surfaced by a curator gets caught before it ranks on arXiv/HF.
• Hugging Face: check tracked accounts/orgs for new activity.
• X / Instagram: best-effort via Tavily on the profile URLs in SOURCES.md. These are unreliable in 2026 (no free API); if a profile can't be fetched, log "X/IG degraded: unreachable" in logs/source_rotation.md and move on — do not fabricate.

Source lists (iterate every entry — the list is the contract)

Like radar-lab-sweep, this skill does NOT name individual channels/blogs in its prose; the data lives in SOURCES.md and you execute ALL of it. The lists to iterate every run:

• SOURCES.md → "Social & community channels" (Reddit subs, Hacker News, X/IG).
• SOURCES.md → "YouTube — TRUSTED-CURATOR POINTER LANE" (one feed per channel).
• SOURCES.md → "Curated digests + explainer/aggregator blogs" (the pointer/digest blogs — fetch each by its recorded method: feed, or tvly extract of its index for feed-less ones). For each list: iterate EVERY entry, fetch by its recorded access method, log each as opened or degraded: <reason>. A new source you find goes INTO the relevant SOURCES.md list (so it is iterated next run), never just into the skill prose.

Discovery fast-track (the main point)

When a social signal LINKS TO or NAMES a primary artifact (repo, release, paper, official blog post), do not just queue the rumour — FOLLOW the link in the same run and verify the artifact via radar-source-verify. If the artifact clears the evidence rules, it becomes evidence THIS run, cited to the primary source (never to the social post). Social is how you find it days early; the primary artifact is what you cite. Only when there is no reachable artifact yet does the signal stay a queue item.

A NAMED primary has exactly TWO valid end-states, never a third: (a) verified → evidence, or (b) an observation_queue item carrying the named id/URL. "Intake — no action", "noted", "hit-attributed to " are NOT end-states: attribution records WHERE you saw it, capture records WHAT it is, and only the queue/ledger is capture — report prose and SOURCES notes are not. "We already know this is a miss" is the trap, not an excuse: if a named primary is recognized but is not in the queue or the ledger, it has been LOST, so queue it now. (The failure this prevents: a primary named repeatedly in report/SOURCES prose and attributed to a curator, yet never followed to its artifact, verified, or queued — so the radar never even holds its id.)

For signals without an artifact: if it points to something concrete but not yet findable, log a queue item ("verify "); if it is pure sentiment, hold it for the pulse note. Cap at ~5 pulse items per run — but a field-shaking event (below) always makes the cut, even off-axis.

Don't miss the earthquake (field-shaking events)

The pulse's job is NOT only to extract on-axis signal — it is also to notice when the ground moves. The classic failure: the top post of your #1 community is a field-shaking story, but you discard it because it doesn't map to a tracked axis. Do not do that.

• Check ALL channels, not one — never collapse the pulse to HN. The earthquake check is multi-channel every run: HN front page (Algolia) + the broad Reddit subs + the trusted curators + the digests; X best-effort. HN is the reliable backbone, but an HN-only pulse is incomplete — and the report must NAME which channels were actually checked (a single-channel pulse is a visible gap to fix, not "done"). Cross-posting is your friend: a real field-shaking event shows up across several of these within hours, so checking the reliable set catches it even when X/Reddit-direct are flaky.
• Cross-community virality = importance. If one event is dominating the top of a major community — or several communities at once (technical AND broad) — that IS the signal, on-axis or not. Surface it.
• Vendor-neutral. This applies to the WHOLE field, not any one company: OpenAI, Google, Meta, Anthropic, Mistral, xAI, regulators, the open-weight labs — whoever the earthquake involves. Do not over-index on a single vendor; the test is "is the field consumed by it", not "which logo is on it".
• Where it lives. A field-shaking event that is not a research/engineering trend (a model ban, an abrupt global access cut, a vendor/government action, an acquisition, a major outage) does NOT go in the trend ledger and is NOT evidence — but it MUST appear in the community-pulse note ("the community is consumed by X"). The radar must say the ground moved, even when it has no trend for it. Follow to a primary source if one exists; otherwise log it as the dominant unverified pulse item with the thread link.
• Test: if a practitioner would say "how did your radar not mention THAT?", it belonged in the pulse. Operational earthquakes (a model you depend on vanishing) count, even though they are not papers or releases.

Self-maintenance (agent owns this)

• Add researcher/lab handles, subreddits, channels to SOURCES.md as you find ones that recur with signal; drop channels that produce only noise (one-line reason in the report).
• If a platform is persistently unreachable for 2+ weeks, note it and stop trying until conditions change.
• Propose, via the weekly amendment process, any change that would need new env secrets (e.g. a paid X API) — the curator decides those, not the agent.
