name: pulse
description: >-
Community-pulse research on any topic — "what are people saying about X right
now." Fans out parallel sub-agents across web search, Hacker News, Reddit, and
GitHub; ranks findings by real engagement (points/upvotes/stars/comments);
flags rumors; and writes a cited brief to chat plus saved .md and .html files.
Use when the user wants the current community conversation / recent buzz /
sentiment / "last 30 days" view on a person, product, project, or concept —
e.g. "/pulse <topic>", "what's the buzz on X", "what are people saying about
X lately", "research recent discussion on X". For exhaustive, adversarially
fact-checked web reports, prefer the deep-research skill instead.

# pulse — community-pulse research
`/pulse <topic> [window/flags in plain language]`
Answer one question: **what is the community actually saying about this topic right
now, and what's resonating?** You ground every claim in a real source and rank by
real engagement — not by what a search engine's editors surfaced.
This skill is deliberately **keyless**: it uses only the agent's native `WebSearch`
/ `WebFetch` tools plus free public endpoints. Never ask the user for API keys.
## How this differs from `deep-research`
- `deep-research` = exhaustive, adversarially fact-checked, authoritative web report.
- `pulse` = fast, recent, **community/engagement-ranked** snapshot. Optimize for
"what's being discussed and how much it's resonating," not for proving every claim.
If the user clearly wants an exhaustive verified report, suggest `deep-research`.
## Inputs
- **Topic** (required): a person, product/company, project/repo, or concept/event.
- **Window** (optional, plain language): default **last 30 days**. Honor overrides
like "last week", "past 6 months", "this year". Record the resolved window.
- Any other plain-language steering ("focus on Reddit", "ELI5", "just the drama").
## Step 0 — Resolve scope (ask only if genuinely ambiguous)
Run immediately for clear topics. Ask **1–2 quick questions only if**:
- the name maps to multiple plausible entities (e.g. a common name, an ambiguous
product), **or**
- there's no obvious angle and the result would likely research the wrong thing.
Otherwise proceed and state your assumptions in the brief header.
**Auto-detect the topic type** and weight sources accordingly:
| Detected type | Source emphasis |
| -------------------- | --------------------------------------------------- |
| Person (dev/tech) | GitHub (velocity) + Hacker News + web + Reddit |
| Person (non-tech) | Web + Reddit (skip/deprioritize GitHub) |
| Product / company | Reddit + web + Hacker News (GitHub if it's a tool) |
| Project / repo / tool| GitHub + Hacker News + Reddit + web |
| Concept / event | Web + Hacker News + Reddit (skip GitHub) |
Do light **entity resolution** first when useful (e.g. the canonical subreddit, the
GitHub `owner/repo` or username, the official site) so sub-agents search the right
handles rather than guessing.
## Step 1 — Fan out: parallel source sub-agents
Spawn the relevant source sub-agents **concurrently** (one message, multiple `Agent`
calls). Skip sources the topic type deprioritizes. Give each the topic, resolved
entities, and the time window. Each sub-agent must return **structured findings**:
for every item — `title`, `url`, `source`, `engagement` (the raw metric + its kind),
`date`, and a 1–2 sentence `snippet`. Then it deepens its **top 2–3** items
(below). Each gathers ~8–10 candidates before deepening.
Use `subagent_type: "Explore"` (read-only, fast) for fetch-heavy sources.
+ **Effort scaling:** match the fan-out to the ask. A niche topic or an explicit
+ "quick check" needs only the 2 best-matched sources from the table; the full
+ fan-out is for broad or clearly hot topics. **Lossless hand-off:** if a
+ sub-agent's deepened findings run long (many quotes/threads), have it write the
+ full extracts to `pulse-briefs/.work/<source>.md` and return just its ranked
+ summary — read the files at synthesis instead of losing detail in the relay.
+
### Web sub-agent
- Use `WebSearch` with several query variations (topic + "news"/"review"/"discussion"
+ recency terms). Prefer results inside the window.
+ - **Authority over SEO:** prefer primary sources (official posts, the actual
+ thread/repo, named practitioners) over SEO-optimized aggregators and listicle
+ farms. A claim that appears *only* on low-quality aggregator sites is
+ low-trust — mark it accordingly.
- Engagement proxy: publication prominence + how often a story recurs across results.
- Deepen top 2–3: `WebFetch` the article and extract the core claim + any quotes.
### Hacker News sub-agent (free Algolia API — most reliable signal)
- Search: `WebFetch` →
`https://hn.algolia.com/api/v1/search?query=<TOPIC>&tags=story&numericFilters=created_at_i>UNIX_START`
(compute `UNIX_START` with a real shell command — e.g. `date -d '30 days ago' +%s`
— never guess the timestamp; for relevance over recency use `/search` instead
of `/search_by_date`).
- `engagement` = `points` and `num_comments`.
- Deepen top 2–3: fetch `https://hn.algolia.com/api/v1/items/<objectID>` and pull the
highest-signal top-level comments (the actual takes).
### Reddit sub-agent (best-effort, keyless)
- Try `WebFetch` on public JSON:
`https://www.reddit.com/search.json?q=<TOPIC>&sort=top&t=month` (map `t` to the
window: `week`/`month`/`year`), and/or `https://www.reddit.com/r/<SUB>/search.json?...&restrict_sr=1`.
- `engagement` = `ups` (upvotes) and `num_comments`.
- Deepen top 2–3: fetch the thread JSON (`<permalink>.json`) and pull top comments.
- **Fallback chain on 403/empty:** first retry the same JSON paths on
`old.reddit.com` (often served when `www` is blocked); if that also fails, use
`WebSearch` for `site:reddit.com <topic>` and `WebFetch` the threads.
**Note in the brief that Reddit was reached via fallback.**
### GitHub sub-agent (keyless REST, 60 req/hr)
- Repo/tool topic: `https://api.github.com/search/repositories?q=<TOPIC>&sort=stars`,
then for the chosen repo pull recent `commits`, `releases`, and open/closed PR
counts to gauge shipping velocity.
- Person topic: resolve the username, then `users/<u>` + recent `users/<u>/events`
(public) to summarize what they're shipping.
- `engagement` = stars, recent commit/PR/release cadence.
If a source returns nothing usable after its fallback, record it as **unreachable**
— do not fabricate.
## Step 2 — Synthesize (main agent)
0. **Check for a previous pulse (delta memory):** look for earlier
`pulse-briefs/<slug>-*.md` files for this topic. If one exists, read the most
recent one and compute the delta for a **Since last pulse** section: which
clusters are new, which previous stories have faded, and which previously
Disputed/Unconfirmed items have since been confirmed or debunked (say which,
with a source). This is what makes repeat pulses on a tracked topic useful —
the delta, not a second snapshot. Skip silently on the first run for a topic.
1. **Dedup & cluster:** merge the same story appearing across sources into one
cluster; keep the strongest engagement signal and cite all sources in the cluster.
2. **Rank** clusters by engagement (normalize across kinds — treat HN points, Reddit
upvotes, GitHub stars, and comment volume as comparable "this resonated" signals;
weight recency within the window).
3. **Flag reliability:** explicitly tag rumors, speculation, single-source claims,
and contested items as **Disputed/Unconfirmed**. Never let a rumor read as fact.
4. **Pull Best Takes:** 2–5 genuinely notable/clever/viral quotes, each attributed
with its source and engagement.
## Step 3 — Emit the brief
Render this template **in chat**, then save it as `.md` and a self-contained `.html`
file (see Output files). Cite inline as `([source], <engagement>)` with a linked URL.
```markdown
# Pulse: <Topic>
**Window:** <resolved window> · **Run:** <YYYY-MM-DD> · **Type:** <detected type>
**Sources reached:** Web ✓ · Hacker News ✓ · Reddit ✓/fallback/�— · GitHub ✓/�—
## TL;DR
- 3–5 bullets: the headline state of the conversation right now.
## Since last pulse (<date of previous brief>)
- **New:** <clusters that weren't in the previous brief>
- **Faded:** <previous headline items with no fresh activity>
- **Resolved:** <previously unconfirmed items now confirmed/debunked, with source>
(omit this section entirely on the first pulse for a topic)
## Key Developments
For each ranked cluster:
### <Cluster headline>
What happened + why it resonates. Inline citations with engagement metrics and links.
Merge cross-source coverage here.
## Best Takes
> "<quote>" — <author/handle>, <source> (<engagement>) [link]
## Disputed / Unconfirmed
- <claim> — why it's uncertain, who's pushing back. (omit section if empty)
## Sources
Flat list of every cited URL, grouped by source, with engagement metrics.
```
If the user asked for ELI5, prepend a short plain-language summary above TL;DR.
## Output files
Save to `./pulse-briefs/` in the current working directory:
- `pulse-briefs/<slug>-<YYYY-MM-DD>.md` — the markdown brief verbatim.
- `pulse-briefs/<slug>-<YYYY-MM-DD>.html` — a **bespoke, distinctively designed**
brief (see below). Self-contained: inline `<style>`, **no JavaScript**, links
preserved, engagement metrics visible, responsive, print-friendly.
`<slug>` = topic lowercased, non-alphanumerics → hyphens. Compute the date with a
shell command (e.g. `date +%F`) — do not guess it. Create `pulse-briefs/` if needed,
and ensure `.gitignore` ignores it (the skill setup adds this once).
Tell the user the two saved paths at the end.
### Designing the HTML brief
Do **not** pour the content into a fixed template — every brief gets its own design.
Invoke the **`frontend-design`** skill (Skill tool) and have it design the HTML for
this specific brief, treating the topic as the design subject:
- **Brief for the designer:** the subject is *this topic and its community
conversation*; the audience is someone scanning "what's happening now"; the page's
one job is to make the TL;DR, ranked Key Developments, Best Takes, and
Disputed/Unconfirmed items instantly scannable, with engagement metrics as
first-class visual elements. Ground the aesthetic in the topic's own world (a dev
tool, a person, a cultural event each suggest a different visual identity) so no two
briefs look alike.
- **Hard constraints (pass these to `frontend-design`):** single self-contained
`.html` file, **inline CSS only, no JavaScript, no external requests/CDNs/web
fonts** (system font stack), keep all source links and engagement numbers, must be
readable on mobile and when printed, and **must include every section** of the
brief template (header with sources-reached, TL;DR, Since last pulse when
present, Key Developments, Best Takes, Disputed/Unconfirmed, Sources) with the
exact same content as the `.md`.
- Render the markdown brief content faithfully into that design — design changes the
presentation, never the facts, citations, or engagement metrics.
If the `frontend-design` skill is unavailable, fall back to a clean self-contained
dark-mode, no-JS layout — but prefer the designed output.
## Guardrails
- **Keyless only.** Never request or use API keys. Degrade gracefully.
- **No fabrication.** Every claim → a real fetched source. Mark unreachable sources
honestly in the header.
- **Recency discipline.** Stay inside the window; if a pivotal item is older, include
it but label it as background/older context.
- **Engagement is the spine.** Order by what resonated, show the numbers inline.
- **Speed over exhaustiveness.** This is a pulse, not a dossier — for the latter,
point to `deep-research`.
