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.

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 | $0.00139 | $0.01226 |
| Opus 5 | $0.00069 | $0.00613 |
| Sonnet 5 | $0.00028 | $0.00245 |
| Haiku 4.5 | $0.00014 | $0.00123 |
Grade A, and why
home-3d-printing 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 10d 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.
- Never curl the heat/move endpoints directly to skip the gate. How it starts
The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Home 3D Printing
Drive the printer through $PC (printctl) — the source of truth; this skill is the runbook. Physical hardware that heats and moves: safety gates are not optional, and no step may route around them.
This setup is not hardcoded. Printer host, model, nozzle, material and safety caps all live in $AXON_PERSONAL_ROOT/config/printing.json and are surfaced (and, when the printer is on, live-discovered) by $PC doctor. Run $PC doctor first and read the real values off it — never assume a printer model or temp from this document.
Variables
| var | value | notes |
|---|---|---|
$PC |
scripts/printctl |
launcher → $AXON_ROOT/capabilities/printing/printctl.py (runs via uv) |
$HOST $MODEL $MATERIAL $NOZZLE_MAX $BED_MAX |
(from config) | host, printer model, loaded filament, hard temp caps — all read from the overlay config; $PC doctor prints them. Never inline them here. |
$STL |
— | model to slice (.stl/.3mf) |
$GCODE |
${STL%.*}.gcode |
slice output, sits next to $STL |
$FN |
$(basename $GCODE) |
filename as the printer sees it (arm/start key) |
$WALLS / $INFILL |
4–6 / 40–50% gyroid |
generic strength-part guidance, not a fixed setting |
Safety model — non-negotiable
- Caps (
$NOZZLE_MAX/$BED_MAX) enforced on sliced gcode and atarm. Above → refused. - Arm-before-heat:
start/resumerefuse unless$FNwasarmed. Arming IS the human "go"; after it, start+monitor run unattended within caps. - Runaway temp/motion →
$PC estopimmediately (halts Klipper; needs FIRMWARE_RESTART after). - Never curl the heat/move endpoints directly to skip the gate.
Preflight — gate on the output
$PC doctor, then branch:
moonraker: REACHABLE ✓→ continue.moonraker: unreachable→ printer off/asleep or off-LAN. Stop, ask the user to power it on. Do not retry blindly.- any preset shows
(unset)ornot found→ headless slicing unconfigured. Readreferences/setup.md, stop at the one-time GUI step (needs the user).
What ships with it
3 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.
- 10d ago First seen · 60 lines · 139 tokens per session scan A 59219993757d
home-3d-printing is a skill published in the GitHub repository larsboes/Axon (1 stars, last pushed yesterday), licensed MIT. It adds 139 tokens to every session and 1,226 once invoked, about $0.0007 per session on Opus 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 2026-08-31.
