What it does

Pp Ufo is an agent skill from mvanhorn/printing-press-library. The declassified UAP file archive in your terminal — browse, search, and download 162+ files from the PURSUE initiative, organized by government release tranche. Trigger phrases: check UFO files, search declassified UAP, download PURSUE files, war.gov UFO, browse UFO archive, latest UFO release, did a new UFO batch drop, compare UFO releases, use ufo.

Its SKILL.md is about 3.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Official library of CLIs generated by the CLI Printing Press. Endorsed, tested, and community-contributed. The licence is Apache-2.0.

When your agent uses it

  • Phrases: check UFO files
  • Search declassified UAP
  • Download PURSUE files
  • Browse UFO archive

Example prompts

  • “/pp-ufo”

Requirements

  • Node.js
  • Pre-approved tools (allowed-tools): Read, Bash

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Install via the Printing Press installer
  2. Verify: ufo-goat-pp-cli --version
  3. Ensure $GOPATH/bin (or $HOME/go/bin) is on $PATH.

What it can do on your machine

Read from SKILL.md and the folder at commit d9a1696. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Bash

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • go
    • claude
    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Pp Ufo loads about 3.4k tokens when it runs. Until then it costs about 95 tokens; SKILL.md has 1,429 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~95
When it runs · the whole SKILL.md, loaded when a task matches
~3.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Bash

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

UFO GOAT — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the ufo-goat-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:
    bash
    npx -y @mvanhorn/printing-press-library install ufo-goat --cli-only
  2. Verify: ufo-goat-pp-cli --version
  3. Ensure $GOPATH/bin (or $HOME/go/bin) is on $PATH.

If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer):

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

If --version reports "command not found" after install, the install step did not put the binary on $PATH. Do not proceed with skill commands until verification succeeds.

The first CLI for the War.gov/UFO declassified files portal. Search across every contributing agency (DoD/DoW, FBI, NASA, State, CIA, DOE, ODNI, and more), download files with resume support, track new release tranches, and discover video-PDF pairings — all from a single binary with offline SQLite storage.

When to Use This CLI

Use this CLI when you need to browse, search, or download declassified UAP files from the War.gov PURSUE archive. Ideal for researchers tracking new releases, journalists investigating specific incidents, or agents that need structured access to government UFO data.

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.

Local state that compounds
  • sync — Automatically detect and fetch new file tranches as the government releases them on a rolling basis

    Agents monitoring the PURSUE release schedule get notified of new files without manual checking

    bash
    ufo-goat-pp-cli sync
  • new — Show the files in the latest government release tranche — the 'what just dropped' command, scoped to the batch instead of your sync timing

    When an agent needs to see exactly what the most recent PURSUE batch contained, regardless of when it last synced. Use --release N for an older tranche, or --since/--since-sync for the old sync-timing behavior.

    bash
    ufo-goat-pp-cli new --agent
    ufo-goat-pp-cli new --release 1 --agent
  • releases — Treat the PURSUE batch as a first-class lens: list every tranche, compare two, and detect when a new one lands

    The government declassifies files in batches (release_1, release_2, …). releases summarizes each batch's date, file count, and agency/type mix; releases check is the cron-friendly "did a new batch drop?" probe that exits 3 when nothing is new.

    bash
    ufo-goat-pp-cli releases --agent
    ufo-goat-pp-cli releases diff 1 2 --agent
    ufo-goat-pp-cli releases check --exit-code --agent
Cross-agency intelligence
  • timeline — View a chronological incident timeline spanning 1944-2025 across every contributing agency

    Researchers need to see the full picture: FBI case from 1947 next to a DoW mission report from 2024

    bash
    ufo-goat-pp-cli timeline --after 1960 --before 1970
  • pairs — Find video-PDF pairings so researchers can locate the document that accompanies a video and vice versa

    41 videos have paired documents — this command surfaces the connections instantly

    bash
    ufo-goat-pp-cli pairs --agent
  • agencies — See which agency contributed what: file counts, types, date ranges, and coverage analysis

    Quick answer to 'what did the FBI release vs NASA vs DoW'

    bash
    ufo-goat-pp-cli agencies --json --select name,file_count,types
  • locations — Aggregate incidents by geographic location for mapping and spatial analysis

    25 incidents in Western US, 12 in Syria, 9 on the Moon — spatial patterns emerge from aggregation

    bash
    ufo-goat-pp-cli locations --json
Agent-native plumbing
  • download — Download files with resume support, verification, and progress tracking for the 2.3 GB archive

    The archive is 2.3 GB of PDFs alone — agents need reliable batch downloads with state tracking

    bash
    ufo-goat-pp-cli download --agency FBI --resume

Command Reference

agencies — Government agencies contributing to the PURSUE release

  • ufo-goat-pp-cli agencies — List all contributing agencies with file counts

files — Declassified UAP files (PDFs, videos, images) from FBI, DoD, NASA, State Department

  • ufo-goat-pp-cli files get — Get details of a specific file
  • ufo-goat-pp-cli files list — List all declassified UAP files (filter by --agency, --type, --location, --release)
  • ufo-goat-pp-cli files search — Full-text search across file titles, descriptions, and locations (--release scopes to a tranche)

releases — Browse the archive by government release tranche (batch)

  • ufo-goat-pp-cli releases — Summarize every release tranche (number, date, file count, agency/type mix)
  • ufo-goat-pp-cli releases diff <from> <to> — Compare the composition of two tranches
  • ufo-goat-pp-cli releases check — Detect whether a new tranche has landed (--exit-code exits 3 when nothing new; --no-sync skips the fetch)

new — Show files in the latest release tranche

  • ufo-goat-pp-cli new — Files in the latest tranche (--release N, or --since/--since-sync for sync-timing)

sources — Configure where the manifest is synced from

  • ufo-goat-pp-cli sources — List known manifest sources (community/legacy/wargov)
  • ufo-goat-pp-cli sync --source <name> — Sync from a named source (or --manifest-url <url>; env UFO_SOURCE / UFO_MANIFEST_URL). Default community tracks every release tranche.
Finding the right command

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

bash
ufo-goat-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.

Recipes

Find all Moon incidents
bash
ufo-goat-pp-cli files list --location Moon --json --select title,agency,incident_date

Surfaces Apollo-era lunar UAP observations from NASA files

Download all FBI files
bash
ufo-goat-pp-cli download --agency FBI --resume

Batch download with resume support for the 56 FBI contributions

Cross-agency timeline for the 1960s
bash
ufo-goat-pp-cli timeline --after 1960 --before 1970 --agent

See incidents across all agencies during the peak UFO era

Show full SKILL.md (620 more words)Show less
Find video-document pairs
bash
ufo-goat-pp-cli pairs --json --select video_title,pdf_title,agency

Discover which videos have accompanying PDF reports

Track new releases by batch
bash
ufo-goat-pp-cli sync && ufo-goat-pp-cli releases --agent

Fetch the latest manifest, then summarize every government release tranche. sync reports any newly-landed batch; releases shows the full batch breakdown. The default community source tracks every tranche; run ufo-goat-pp-cli sources to see or change it.

Detect a newly-dropped batch on a schedule
bash
ufo-goat-pp-cli releases check --exit-code --agent

Cron/scheduler-friendly: syncs, reports any new tranche as JSON, and exits 3 when nothing is new so a wrapper can branch on it.

Browse one release tranche
bash
ufo-goat-pp-cli new --release 1 --agent
ufo-goat-pp-cli files list --release 1 --json --select title,agency,type

Scope any listing to a single PURSUE batch via --release N (also on search and timeline).

Auth Setup

No authentication required.

Run ufo-goat-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. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:

    bash
    ufo-goat-pp-cli agencies --agent --select id,name,status
  • Previewable — --dry-run shows the request without sending

  • Offline-friendly — sync/search commands can use the local SQLite store when available

  • 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

Commands that read from the local store or the API wrap output in a provenance envelope:

json
{
  "meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
  "results": <data>
}

Parse .results for data and .meta.source to know whether it's live or local. A human-readable N results (live) summary is printed to stderr only when stdout is a terminal — piped/agent consumers get pure JSON on stdout.

Agent Feedback

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

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

Entries are stored locally at ~/.ufo-goat-pp-cli/feedback.jsonl. They are never POSTed unless UFO_FEEDBACK_ENDPOINT is set AND either --send is passed or UFO_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:

SinkEffect
stdoutDefault; write to stdout only
file:<path>Atomically write output to <path> (tmp + rename)
webhook:<url>POST the output body to the URL (application/json or application/x-ndjson when --compact)

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.

ufo-goat-pp-cli profile save briefing --json
ufo-goat-pp-cli --profile briefing agencies
ufo-goat-pp-cli profile list --json
ufo-goat-pp-cli profile show briefing
ufo-goat-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.

Exit Codes

CodeMeaning
0Success
2Usage error (wrong arguments)
3Resource not found
5API error (upstream issue)
7Rate limited (wait and retry)
10Config error

Argument Parsing

Parse $ARGUMENTS:

  1. Empty, help, or --help → show ufo-goat-pp-cli --help output
  2. Starts with install → ends with mcp → MCP installation; otherwise → see Prerequisites above
  3. Anything else → Direct Use (execute as CLI command with --agent)

MCP Server Installation

  1. Install the MCP server:
    bash
    go install github.com/mvanhorn/printing-press-library/library/other/ufo-goat/cmd/ufo-goat-pp-mcp@latest
  2. Register with Claude Code:
    bash
    claude mcp add ufo-goat-pp-mcp -- ufo-goat-pp-mcp
  3. Verify: claude mcp list

Direct Use

  1. Check if installed: which ufo-goat-pp-cli If not found, offer to install (see Prerequisites at the top of this skill).
  2. Match the user query to the best command from the Unique Capabilities and Command Reference above.
  3. Execute with the --agent flag:
    bash
    ufo-goat-pp-cli <command> [subcommand] [args] --agent
  4. If ambiguous, drill into subcommand help: ufo-goat-pp-cli <command> --help.
