Composition axis
Tools
Tools are how an agent touches the world. Two kinds sit on this axis: data sources, which read something public and structured and return a verified answer, and connectors, which act through one of your own accounts.
This is the axis that decides whether an agent can be trusted at all, because it decides whether an answer is grounded or generated. An agent with a real adapter for a site reads that site and reports what is there. An agent without one produces something plausible about it. Those two outputs look identical on the page and are not remotely the same thing, which is why every adapter's description states exactly what it can verify.
Availability is per deployment. An adapter whose credentials are not configured here is marked unavailable rather than hidden, because a tool that looks present and cannot ground anything is worse than one that is plainly missing.
Tools in this deployment
Data-source adapters read live from the scout registry; connector families from the connector list.
| scout.feed | Watch ANY public feed for new items: RSS/Atom/JSON feeds, news sites, blogs, subreddits (use the .json URL), YouTube channel feeds, podcasts, GitHub releases (the releases.atom URL), product changelogs, status pages, job-board RSS. Returns recent items with title, link, date. | available |
| scout.campsites | Check campsite availability (incl. cancellations/openings) for a US campground by name. Covers recreation.gov (national parks, USFS, BLM, Army Corps) and ReserveCalifornia (California State Parks — e.g. San Elijo, Carlsbad). Returns which sites are Available for the requested month. No login needed. | available |
| scout.permits | Check availability/cancellations for hard-to-get US outdoor permits on recreation.gov by name — Mt Whitney, Half Dome, the Enchantments, Angels Landing, Coyote Buttes ("The Wave"), Paria Canyon, wilderness permits. Reports which dates have remaining quota, per division (trailhead/entry point/overnight vs day). Alert-only; no login. Havasupai is NOT on recreation.gov. | available |
| scout.recalls | Check official US product recalls/safety: food & drugs (openFDA) and vehicles (NHTSA). Use for 'alert me to recalls for X'. Returns recent matching recalls with dates and reason. | available |
| scout.weatherAlerts | Active US National Weather Service alerts (warnings/watches/advisories) for a state or area code. Use for 'alert me to severe weather in X'. Official NWS data. | available |
| scout.research | New academic preprints on arXiv matching a topic/author/category. Returns recent papers with title, authors, link, and the ABSTRACT — enough to summarize without fetching each PDF. Use for 'watch arXiv for new papers on X and summarize them'. | available |
| scout.jobs | New job postings from a company's PUBLIC applicant-tracking site. Supports Greenhouse, Lever, Ashby, SmartRecruiters (give the company's board slug) and Workday (give the full careers-site URL). Covers most startup + enterprise career pages without login. Use for 'watch <company> for new <role> openings'. | available |
| scout.xPosts | Read recent posts from a specific public X/Twitter account to use as a SIGNAL inside a larger task — e.g. an agent answering 'what's happening in San Diego this week' checks a few local-events accounts to surface things generic web search misses. Call it across the handful of knowledgeable accounts relevant to the task, then synthesize with your other sources; do NOT just relay one account's posts as the answer. Single public account per call (no search/hashtags/protected). Best-effort; X may change this surface. | available |
| scout.sports | Upcoming games or latest results for a sports team. Use for 'tell me when <team> plays next' or 'did <team> win'. Public TheSportsDB data. | available |
| scout.markets | Latest stock/ETF/crypto quote(s) for one or more symbols (e.g. NVDA, SPY, BTC-USD): price, prior close, and % change. Use for price watches and market briefings. Public data (Yahoo, Stooq fallback); ~15-min delayed. | available |
| scout.airportStatus | Current FAA delay/closure status and weather for a US airport by 3-letter code (e.g. SFO, JFK). Use for 'alert me if <airport> has delays'. | available |
| scout.federalRegister | New US Federal Register documents (rules, proposed rules, notices) matching a term. Use for regulatory/policy watches. Official government data. | available |
| scout.polymarket | Prediction-market signal from Polymarket (public, read-only — never places bets). mode='trending': the markets the money is watching now (optionally filtered by a topic keyword) — an excellent selector for 'what consequential, uncertain things should I follow'. mode='topic': a specific subject's current crowd-implied probability and 24h move. Pair with web/news scouts to report what actually moved the odds. | available |
| scout.conditions | Outdoor conditions forecast for any place — temperature, rain chance, wind, UV, cloud cover, sunshine, sunrise/sunset, and (marine:true) wave height/period. The "is it a good day for X" source: beach, surf, stargazing, running, skiing, gardening, golf, sunset-watching. Returns up to 7 days of normalized daily signals; the agent judges what is "good" for its goal. | available |
| scout.iss | Upcoming VISIBLE International Space Station passes for a place — when to step outside and look up. Returns each pass: local start/peak/end time, max elevation, the path across the sky (e.g. WNW→SE), duration, and a viewability rating (prime = bright & high; faint = dark but ISS likely shadowed; daylight = not visible). Public data (g7vrd + Open-Meteo), no key. | available |
| scout.api | Fetch a PUBLIC, read-only JSON or CSV endpoint and extract items — the generic data source for anything without a dedicated scout. Use when the user names a specific public API/endpoint, or a known public API covers the data and no other scout fits. GET only, no auth/keys, SSRF-protected. Prefer over web search when a real public API exists. MARKET / COMMODITY / METALS / FX / EQUITY / INDEX / RATES / INFLATION / any economic time-series — pick by freshness: (1) a DAILY spot/close (most commodities, FX, indices, equities, ETFs) → keyless Stooq snapshot, url `https://stooq.com/q/l/?s=<sym1>+<sym2>&f=sd2t2ohlcv&h&e=csv` format `csv` (one call, today's OHLC for many symbols; copper `hg.f`, gold `gc.f`, silver `si.f`, WTI `cl.f`, natgas `ng.f`, zinc `zi.f`, nickel `ni.f`, FX as `eurusd`, index as `^spx`, US equity/ETF as `aapl.us`; `N/D` = not carried, use (2)); (2) a series Stooq lacks daily — interest rates, inflation, unemployment, macro indices, LME lead/aluminium → keyless FRED CSV, url `https://fred.stlouisfed.org/graph/fredgraph.csv?id=<SERIES_ID>` format `csv` (rows newest-first; MONTHLY, lags ~1-2mo). FRED ids: lead `PLEADUSDM`, copper `PCOPPUSDM`, aluminum `PALUMUSDM`, WTI oil `DCOILWTICO`, natural gas `DHHNGSP`, 10y treasury `DGS10`, CPI `CPIAUCSL`. Never present a monthly/proxy figure as today's — say what it is. EFFICIENCY: narrow server-side via `params`, set `fields` to only what you need, keep `maxItems` small (5–15), use `path` to the results array. Pulling the full unfiltered payload is slow and costly. TIMEZONE: when the API returns ISO 8601 timestamps (launch times, event dates, anything ending in `Z` or with a `+HH:MM` offset), ALWAYS set `timezone` to the user's local IANA timezone (e.g. `America/Los_Angeles`). Every timestamp is then replaced with an object `{raw, local, weekday, date_local, time_local, tz}` — quote the `local` and `weekday` fields verbatim. Do NOT derive weekday or local time yourself; LLMs get it wrong (off-by-one days, missed UTC offsets, stale math when other fields update). The structured fields are the source of truth. | available |
| scout.browse | Read a PUBLIC web page that loads its data via JavaScript (an availability calendar, a SPA dashboard, a JS-rendered listing) when no dedicated scout fits. Renders the page in a real browser and returns the data the page itself fetched plus its visible text. No login. Pass the page URL; optionally hint at the data API host/path to capture. | available |
| scout.tickets | Live event tickets via Ticketmaster — concerts, sports and theatre. Search by artist/team/event keyword and/or city; returns upcoming events with date, venue, price range, on-sale status and a direct Ticketmaster purchase link. Use it to find tickets or to watch for an artist/team announcing a show. No login needed. | not configured |
| scout.kalshi | Regulated prediction markets via Kalshi (CFTC-regulated, US). Search/filter markets by keyword, series or event; returns each market with title, YES/NO ask in cents, 24h volume, close date and a kalshi.com market link. Read-only, no login. Complements scout.polymarket (crypto-native) — use both to compare prices on the same event across platforms. | available |
| scout.pagewatch | Watch ANY public web page for changes — a competitor homepage, a pricing page, a careers page, docs, terms, a status page without a feed. Fetches the page (honoring robots.txt), strips scripts/navigation/chrome, and returns the readable content as numbered stable blocks, each with a content hash, plus an overall blocksHash. Pass prevBlocksHash (the block-hash list you stored last run, e.g. via log.record) to get block-level diff hints: the result then lists ONLY blocks that actually changed, so you report real changes, never guessed ones. LIMITS — state them honestly when relevant: public pages only (no logins, no paywalls); static HTML only (content rendered purely by JavaScript is invisible — scout.browse covers that); pages behind anti-bot challenges are reported as unreadable, never summarized. | available |
| scout.price | Extract the price(s) from a PUBLIC product page — the source for 'email me when the price drops' watches. Prefers schema.org JSON-LD Product/Offer structured data (most retail product pages ship it); when a page has none, falls back to scanning the visible text for currency amounts and returns LABELED CANDIDATES without guessing which one is 'the' price — disambiguate once when setting up the watch (productName narrows to a specific product) and pin the choice. LIMITS — state them honestly when relevant: public pages only (no logins); static HTML only (prices rendered purely by JavaScript are invisible — scout.browse covers that); honors robots.txt; anti-bot/challenge pages are reported as blocked, never parsed. | available |
Connectors
Accounts an agent can act through. Each one connects with your own credentials, so an agent only ever holds the scopes you granted it.

How to choose
Work backwards from the claim you want the agent to make. If it has to assert a fact, there must be a tool that can read that fact — and if there isn't one, the honest move is to narrow the agent rather than let it fill the gap.
Grant the narrowest connector that does the job. Connectors carry your own credentials and the scopes you approved, so the blast radius of a mistake is exactly the access you handed over, and nothing more.
Fewer tools usually beats more. Every additional tool is another description competing for context and another branch the agent can take, and an agent given ten ways to answer often picks a worse one than an agent given two.
There is no automated experiment runner yet. Nothing here sweeps this axis for you — changing it means editing the agent and reading the next run. A compare mode that runs one task across several compositions is named on the index as not built, and that is still true.
