Agent Stuff is a personal package of reusable skills, extensions, prompt commands, themes, and utilities for the Pi Coding Agent. Its author uses these tools across projects, and the catalogue entries are components from this package that support that workflow.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Data Exfiltration · line 149 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00065 | $0.01344 |
| Opus 5.5 | $0.00026 | $0.00538 |
| Sonnet 5.5 | $0.00013 | $0.00269 |
| Haiku 4.5 | $0.00006 | $0.00134 |
Grade A, and why
anachb scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

VOR AnachB - Austrian Public Transport API
Query Austrian public transport for real-time departures, route planning, and service disruptions using the HAFAS API.
Quick Reference
| Script | Purpose |
|---|---|
search.sh |
Find stations/stops by name |
departures.sh |
Real-time departures at a station |
route.sh |
Plan a trip between two locations |
disruptions.sh |
Current service disruptions |
API: HAFAS (Hacon Fahrplan-Auskunfts-System)
Endpoint: https://vao.demo.hafas.de/gate
1. Search Stations/Stops
Find station IDs by name:
./search.sh "Stephansplatz"
./search.sh "Wien Hauptbahnhof"
./search.sh "Linz"
./search.sh "Salzburg Hbf"
Returns station names, IDs (extId), and coordinates.
Response fields:
name: Station nameextId: Station ID for use in other queriestype: S (Station), A (Address), P (POI)coordinates: WGS84 coordinates (lon/lat in 1e-6 format)
2. Real-Time Departures
Get next departures from a station:
./departures.sh <station-id> [count]
# Examples:
./departures.sh 490132000 # Wien Stephansplatz, 10 departures
./departures.sh 490132000 20 # Wien Stephansplatz, 20 departures
./departures.sh 490060200 # Wien Hauptbahnhof
./departures.sh 444130000 # Linz Hbf
./departures.sh 455000100 # Salzburg Hbf
Response fields:
line: Line name (U1, S1, RJ, etc.)direction: Final destinationdeparture: Scheduled departure timedelay: Delay in minutes (if any)platform: Platform/track number
3. Route Planning
Plan a trip between two stations:
./route.sh <from-id> <to-id> [results]
# Examples:
./route.sh 490132000 490060200 # Stephansplatz → Hauptbahnhof
./route.sh 490132000 444130000 5 # Wien → Linz, 5 results
./route.sh "Graz Hbf" "Wien Hbf" # Search by name (slower)
Response fields:
departure: Departure timearrival: Arrival timeduration: Trip durationchanges: Number of transferslegs: Array of trip segments with line info
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

anachb is a skill published in the GitHub repository mitsuhiko/agent-stuff (3,192 stars, last pushed 21d ago), licensed Apache-2.0. It adds 65 tokens to every session and 1,344 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
