Shakedown Feature Forge

Shakedown Feature Forge is a skill for Claude Code, Codex from notforyou23/home23. It costs 39 tokens per session (2,856 once invoked), scanned A, original, MIT.

A research and writing process for producing a sourced Shakedown feature about a Grateful Dead, Garcia, Hunter, JGB, song, performance, or related subject. It starts with one central idea and tests it against evidence.

In plain words
What is it for?
Use it to closely read a song or performance, find authoritative evidence, develop the governing idea, test that idea, and write the complete feature.
Why use it?
It gives a feature a clear argument and story structure instead of producing a loose collection of facts or notes.

Token cost

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.

Security

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 9d 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.

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:

  1. close-read the primary object
  2. state a provisional governing idea
  3. derive bounded research threads that could prove or break it
  4. gather and validate authoritative sources claim by claim
  5. follow meaningful discrepancies and variants
  6. build an argument-shaped narrative movement
  7. draft the complete sourced feature
  8. run the adversarial editorial pass
  9. freeze the pre-voice manuscript

The action ends at a verified manuscript. Publishing and voice rewriting are separate actions.

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.
