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.

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 | $0.00039 | $0.02856 |
| Opus 5.5 | $0.00016 | $0.01142 |
| Sonnet 5.5 | $0.00008 | $0.00571 |
| Haiku 4.5 | $0.00004 | $0.00286 |
Grade A, and why
Shakedown Feature Forge 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 339 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Shakedown Feature Forge
This skill memorializes the successful pre-rewrite process used to make “The Mandolin Knows” from “Rubin and Cherise” on August 10, 2026.
Its product is a complete, sourced feature with a real governing idea. It is not a dossier, topic card, pipeline state transition, publishing operation, or jtr-voice rewrite.
The central rule
Find the sentence that makes the whole piece legible, then try to prove it wrong.
For “Rubin and Cherise,” that sentence was:
Reuben can lie, but his mandolin cannot.
That was not a decorative headline added after research. It selected the research, organized the evidence, and became the article’s spine. The second pressure point—this deeply Garcia song barely became a Grateful Dead song—supplied the historical counterweight.
Do not begin by filling a template. Do not begin with the pipeline. Begin by reading the thing closely enough to have a take.
When to use
Use this skill when jtr names a Garcia, Hunter, Grateful Dead, JGB, song, performance, object, collaborator, or episode and wants the actual Shakedown story found and written.
Especially use it when he says:
- “straight up”
- “just do the piece”
- “find the story”
- “give it the Rubin and Cherise treatment”
- the pipeline is unfinished or would distract from the editorial work
Do not use it for:
- publishing or distribution
- a routine factual lookup
- a voice-only rewrite
- backlog selection
- North Star gap-filling
- forcing a weak subject into an article
Actions
forge
Run forge as one editorial workflow:
- close-read the primary object
- state a provisional governing idea
- derive bounded research threads that could prove or break it
- gather and validate authoritative sources claim by claim
- follow meaningful discrepancies and variants
- build an argument-shaped narrative movement
- draft the complete sourced feature
- run the adversarial editorial pass
- freeze the pre-voice manuscript
The action ends at a verified manuscript. Publishing and voice rewriting are separate actions.
What ships with it
2 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.
