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 | $0.00055 | $0.00642 |
| Opus 5 | $0.00028 | $0.00321 |
| Sonnet 5 | $0.00011 | $0.00128 |
| Haiku 4.5 | $0.00006 | $0.00064 |
Grade A, and why
yolo-plan 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 6d 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 — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.
yolo-plan
Turn a goal into an ordered set of small, testable tasks. One task = one commit.
Inputs
- The brief (
workspace/features/<slug>/brief.md) and, if present,…/research.md.
Procedure
- Decompose the goal into tasks small enough that each is one focused commit (roughly 2–5 steps of work).
- For each task define: a kebab-case
id,title,description, thefilesit touches, atest_spec(the tests to write/update — required for non-scaffolding tasks),relevant_tests(paths to existing tests that already cover the touched code — the contract to keep green; the executor loads these into context, since the measured TDD win is knowing which tests to check, not the ritual), a one-lineverification, anddepends_on(task ids). - Discover the project's
lint_commandsandtest_commandsfrom its config (package.json scripts, Makefile, pyproject, etc.) and record them — yolo-verify reuses them. - Order tasks by dependency.
Output
Write workspace/features/<slug>/plan.md as YAML:
tasks:
- id: add-csv-export
title: "Add CSV export endpoint"
description: "..."
files: ["src/export.ts"]
test_spec: "src/export.test.ts: happy-path export + empty-dataset"
relevant_tests: ["src/reports.test.ts"] # existing tests covering this area — keep green
verification: "GET /export returns text/csv"
depends_on: []
lint_commands: ["eslint ."]
test_commands: ["npm test"]
Commit the plan (yolo: plan <slug>).
Execution contract (consumed downstream)
- Each task is implemented test-first — its
relevant_tests(existing contract) andtest_spec(new tests) are loaded into the executor's context — and committed with the trailerYOLO-Task: <id>(<id>matches the task'sidfield; see.claude/yolo/conventions.md). - Present the plan for approval before any code is written — this IS the plan gate, the first of YOLO's two confirmations (
.claude/yolo/conventions.mdThe two gates). Lead with the key findings/assumptions from research the plan rests on (a wrong assumption is the costliest thing to catch late — research-review is higher-leverage than diff-review), then the tasks. Skip only if the user pre-consented ("just go").
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.

yolo-plan is a skill published in the GitHub repository CoriChui/yolo (9 stars, last pushed 2mo ago), licensed MIT. It adds 55 tokens to every session and 642 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.
