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 | $0.00000 | $0.00337 |
| Opus 5.5 | $0.00000 | $0.00135 |
| Sonnet 5.5 | $0.00000 | $0.00067 |
| Haiku 4.5 | $0.00000 | $0.00034 |
Grade A, and why
jokes scanned grade A with 0 findings 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
jokes Pipeline
Purpose: provide a tiny standalone native-first pipeline that declares:
"I'm a native driver, I need dispatch+emit." The native declaration compiles
a NativeProgram through @pipeline / @phase decorators and
compile_pipeline, and build_pipeline() returns a projected
Pipeline shell whose native_program field is non-null. It drafts,
tightens, and emits a joke artifact without delegating to the creative
pipeline.
Topology:
draft -> tighten -> emit -> halt
Stages:
| Stage | Prompt key | Behavior |
|---|---|---|
draft |
draft_joke |
Dispatches the initial premise and writes the draft artifact. |
tighten |
tighten_joke |
Reads prior artifacts from state and sharpens the joke beat. |
emit |
emit_joke |
Emits the final artifact path into state["joke_artifact"]. |
Verdicts: no planning gate vocabulary; each stage returns the next native
phase label and the final stage returns halt.
Native Dispatch
The native_program attached to the projected Pipeline is an
execution-level dispatch substrate — it describes the phase ordering, entry
point, and instruction set consumed by the native runtime. It does not
encode final visible compositional semantics (those are deferred to the
Megaplan composition layer). The graph-projected shell is a structural
reflection of the native program and exists for inspection, port binding,
and compatibility; the native program is the authoritative execution
contract.
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.

jokes is a skill published in the GitHub repository peteromallet/Arnold (98 stars, last pushed yesterday), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 337 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
