Pp Shelters

Shelters — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the shelters-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:

   npx -y @mvanhorn/printing-press-library install shelters --cli-only
   

2. Verify: shelters-pp-cli --version
3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer). This installs into $GOPATH/bin (default $HOME/go/bin), so add that directory to $PATH instead:

go install github.com/mvanhorn/printing-press-library/library/other/shelters/cmd/shelters-pp-cli@latest

If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds.

Gives agents and people the most comprehensive, credible open-shelter picture available: it unions FEMA's National Shelter System (NSS) OpenShelters feed with the American Red Cross Emergency-Action feed (the redcross.org map's source) and dedupes them, because FEMA is synchronized downstream of Red Cross and lags it by up to a day, so neither feed alone is complete. Coverage is the United States and its territories only (both FEMA NSS and the American Red Cross are US feeds), not other countries. FEMA rows are best-effort enriched with the richer FEMA_NSS layer (county/parish, the driving incident, the open date, generator and floodplain/surge attributes), and the CLI folds in live occupancy (current population, the general/medical/other/pet breakdown, capacity, and the driving incident) from the American Red Cross Open_Shelters layer, the one feed that reports a real headcount. Every shelter carries a source field recording which feeds it came from ('fema', 'redcross', or 'fema+redcross', with '+occupancy' appended once live population is merged in). It shows only publicly listed shelters: the Open_Shelters roster is used to fill population onto shelters already in the public feeds, never to add one, and any shelter the Red Cross keeps off its public map (hide_from_public) is dropped even when FEMA's feed lists it, so the tool stays conservative about never directing people to a site the Red Cross has not cleared for the public. It answers the questions people actually ask in a disaster, like 'the closest open shelter to me that allows pets' and 'which shelters are at capacity', filters by state, pets, accessibility, county, or generator, geocodes addresses (and bare ZIPs) when coordinates are missing, and never invents a number it does not have (a missed secondary fetch degrades to explicit null with a note, never a wrong value). Deep thanks to all first responders, emergency management practitioners, and relief nonprofit organizations for the work you do in communities when disaster strikes. This is an unofficial tool; in a life-threatening emergency call 911 and follow the official guidance and evacuation orders from FEMA, the American Red Cross, your local emergency management, and your local authorities.

When Not to Use This CLI

Do not activate this CLI for requests that require creating, updating, deleting, publishing, commenting, upvoting, inviting, ordering, sending messages, booking, purchasing, or changing remote state. This printed CLI exposes read-only commands for inspection, export, sync, and analysis.

Unique Capabilities

These capabilities aren't available in any other tool for this API.

Closest shelter

• near — Ranks open shelters by straight-line distance from a lat,lon, ZIP, or street address; geocodes shelters that are missing coordinates and reports any it cannot locate rather than dropping them; filterable by pets, ADA, wheelchair, county/parish, and confirmed onsite generator.

  Answers 'the closest shelter to me that allows pets' in one call; add --pets, --ada, or --wheelchair.

  shelters-pp-cli near 78566 --pets --limit 3
  

Capacity

• capacity — Computes utilization only where both a population and a capacity are reported, labeling the denominator (evacuation vs post-impact), and surfaces shelters reported FULL without asserting it as ground truth.

  Answers 'which shelter is at capacity?' honestly, marking unknowns as unknown.

  shelters-pp-cli capacity --state TX
  

One-call situational awareness

• brief — One command returns the open count, breakdowns by state and by the driving incident, pet-friendly and accessible counts, and the capacity picture, with an optional human briefing.

  Reach for this first when an agent asks 'what is the shelter situation right now'.

  shelters-pp-cli brief --markdown
  

Listings and detail

• shelters — Open shelters from the union of FEMA OpenShelters and the American Red Cross feed (deduped, each tagged with a source field: fema, redcross, or fema+redcross), flattened and filterable by state, pets, ADA, wheelchair, managing org, status, county/parish, and confirmed onsite generator; FEMA rows best-effort enriched with the richer FEMA_NSS/0 layer (county, the driving incident, generator and floodplain/surge attributes).

  Use to narrow open shelters to the ones that match a person's needs.

  shelters-pp-cli shelters --state FL --ada --json
  

• shelter — Full detail for one shelter joined on the stable shelter_id rather than the churning objectid, with unreported fields as explicit null; enriched with FEMA_NSS/0 fields (county, the driving incident, open date, generator, floodplain/surge, and the population breakdown) when reported.

  Use when you have a shelter_id and need its full record.

Recipes

Closest pet-friendly shelter as compact JSON for an agent

shelters-pp-cli near 29.76,-95.37 --pets --limit 1 --json --select data.shelters

Returns just the nearest pet-friendly shelter so an agent does not burn context on the full feed.

Shelters confirmed wheelchair accessible in one state

shelters-pp-cli shelters --state TX --wheelchair --json

Filters open shelters to those confirmed wheelchair accessible.

Which shelters are at or over capacity

shelters-pp-cli capacity --json --select data.shelters

Reports utilization where computable and flags reported-full shelters, honestly marking unknowns.

One-call situational briefing

shelters-pp-cli brief --markdown

Bundles open count, by-state, by-incident, accessibility, and capacity into a single human-readable briefing.

Open shelters in one county that have a generator

shelters-pp-cli shelters --county Cameron --generator --json

Filters on the FEMA_NSS/0 enrichment fields (county/parish and confirmed onsite generator); matches nothing honestly when the enrichment is unavailable rather than guessing.

Shelters the Red Cross feed has but FEMA does not yet

shelters-pp-cli shelters --json --select data.shelters

The union surfaces shelters tagged source 'redcross' (open on the redcross.org map but not yet in FEMA, which syncs downstream and lags); a consumer can filter on the source field.

FEMA spine only, no Red Cross union or enrichment

shelters-pp-cli shelters --no-enrich --json

Skips both the Red Cross union and the FEMA_NSS/0 enrichment round-trips for the fastest, FEMA-OpenShelters-only answer.

Command Reference

All commands are read-only and need no API key. They fetch the live union (deduped) of FEMA's OpenShelters feed and the American Red Cross open-shelter feed, then fill in live occupancy (current population and capacity) from the American Red Cross Open_Shelters layer (each shelter tagged source fema, redcross, or fema+redcross, with +occupancy appended where live population was merged in), or a --fixture file for offline use, and emit a {source, fetched_at, data} JSON envelope. Occupancy is a fill-only overlay on publicly listed shelters; a site the Red Cross keeps off the public map is never added, and any shelter the Red Cross hides from its public map (hide_from_public) is dropped even when FEMA lists it. Coverage is the United States and its territories only, not other countries.

• shelters-pp-cli shelters (alias list) — Open shelters, filterable by --state, --pets, --ada, --wheelchair, --org, --status, --limit.
• shelters-pp-cli shelter <shelter_id> — Full detail for one shelter, joined on the stable shelter_id.
• shelters-pp-cli near <location> — Closest open shelters to a lat,lon, ZIP, or address; geocodes shelters missing coordinates. Add --pets / --ada / --wheelchair, --limit, --max-miles. Use for "the closest shelter to me that allows pets."
• shelters-pp-cli capacity — Which shelters are at or near capacity, computed only where population and a capacity both exist (denominator labeled), plus any reported FULL. Use for "which shelter is at capacity?"
• shelters-pp-cli brief [--markdown] — One-call situational briefing: open count, by-state, pet-friendly + accessible counts, capacity picture.
• shelters-pp-cli gis-links — Stable FEMA service URLs and the full-NSS access path (link-out only).
• shelters-pp-cli credits — Gratitude to first responders / emergency managers / relief nonprofits, plus the unofficial-tool + safety disclaimer.

Quotas on honesty: coordinates are frequently null (geocoded by near, with anything unlocatable reported in a count), and capacity is never computed against a missing denominator.

Finding the right command

When you know what you want to do but not which command does it, ask the CLI directly:

shelters-pp-cli which "<capability in your own words>"

which resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code 0 means at least one match; exit code 2 means no confident match — fall back to --help or use a narrower query.

Auth Setup

No authentication required.

Run shelters-pp-cli doctor to verify setup.

Agent Mode

Add --agent to any command. Expands to: --json --compact --no-input --no-color --yes.

• Pipeable — JSON on stdout, errors on stderr

• Filterable — --select keeps a subset of fields, with dotted paths descending into the envelope (the data is nested under data). Critical for keeping context small:

  shelters-pp-cli near 78566 --pets --agent --select data.shelters
  

• Previewable — --dry-run short-circuits without sending the request

• Non-interactive — never prompts, every input is a flag

• Read-only — do not use this CLI for create, update, delete, publish, comment, upvote, invite, order, send, or other mutating requests

Response envelope

The shelter commands wrap output in a small provenance envelope:

{
  "source": "<live feed URL | fixture:path>",
  "fetched_at": "<ISO-8601 UTC, stamped client-side because the feed has none>",
  "data": { ... }
}

Parse .data for results and .source to know whether it was live or a fixture. A human listing is printed only when stdout is a terminal AND no machine-format flag (--json, --csv, --compact, --quiet, --plain, --select) is set — piped/agent consumers and explicit-format runs get pure JSON on stdout.

Agent Feedback

When you (or the agent) notice something off about this CLI, record it:

shelters-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
shelters-pp-cli feedback --stdin < notes.txt
shelters-pp-cli feedback list --json --limit 10

Entries are stored locally at ~/.local/share/shelters-pp-cli/feedback.jsonl. They are never POSTed unless SHELTERS_FEEDBACK_ENDPOINT is set AND either --send is passed or SHELTERS_FEEDBACK_AUTO_SEND=true. Default behavior is local-only.

Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.

Output Delivery

Every command accepts --deliver <sink>. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:

Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.

Named Profiles

A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.

shelters-pp-cli profile save briefing --json
shelters-pp-cli --profile briefing shelters
shelters-pp-cli profile list --json
shelters-pp-cli profile show briefing
shelters-pp-cli profile delete briefing --yes

Explicit flags always win over profile values; profile values win over defaults. agent-context lists all available profiles under available_profiles so introspecting agents discover them at runtime.
