What is yoke-retrofit?

A setup guide for Yoke, a shared harness that applies the same project behavior to Claude, Codex, and Gemini coding agents.

Use it when adding or updating Yoke in a project, choosing a code-graph tool, selecting the coding agents it should support, or enabling its loop and decision settings.

It turns project choices about agents, code navigation, autonomous loops, task running, and decision-making into one repeatable setup command.

yoke-retrofit — Skill for Claude Code by HECer

Install

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.

Any agent

npx skills add HECer/yoke --skill yoke-retrofit

Clone the repo

git clone --depth 1 https://github.com/HECer/yoke

Made for: Claude Code.

Or install yoke, the plugin that ships this one along with the rest of its 34 skills, 1 hook.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00050	$0.00476
Opus 5	$0.00025	$0.00238
Sonnet 5	$0.00010	$0.00095
Haiku 4.5	$0.00005	$0.00048

Security

Grade A, and why

yoke-retrofit 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 3d 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

Yoke Retrofit

Set up or update Yoke through the shared yoke setup contract.

Inspect the project and identify the current host (claude, codex, gemini, qwen, opencode, kilo, or pi).
Ask these setup questions one at a time and give a direct recommendation:
- target agents (recommend the current host; use all for deliberately cross-agent projects),
- code-graph tool,
- autonomous loop on/off,
- default runner (recommend the current host),
- decision mode: auto or critical.
Recommend the code graph based on this project:
- Serena is LSP-accurate and best for large typed codebases or systematic symbol refactors where a missed reference is costly. It needs a language server per language.
- graphify is fast and multimodal, and is best for exploration, migration, onboarding, or mixed code and document repositories. Its graph is an index and can become stale.
Apply the answers without a second round of prompts: yoke setup . --yes --host=<host> --agent=<agents> --code-graph=<choice> --runner=<runner> --decision-policy=<auto|critical> --loop|--no-loop. A human who runs yoke setup . directly receives the same five terminal questions.
Show the generated report and backup paths. Existing files are backed up under .yoke/backup/; settings are merged where supported.
If an old generated CLAUDE.md or GEMINI.md contained project-specific instructions, restore them inside its  /  block. Preserve blocks survive every later retrofit.

The generated harness includes the provider-neutral yoke-workflow skill. It owns the planning questions, approved-plan handoff, autonomous stories, and critical-decision resume flow.

Changes

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.

yoke-retrofit is a skill published in the GitHub repository HECer/yoke (2 stars, last pushed 2d ago), licensed MIT. It adds 50 tokens to every session and 476 once invoked, about $0.0003 per session on Opus 5. 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 2026-08-31.
