yolo

yolo is a skill for Claude Code, Codex from howar31/magi-workflow. It costs 117 tokens per session (3,610 once invoked), scanned A, original, MIT.

A headless workflow mode that runs a coding sprint from planning through implementation, review, and committing changes without waiting for user prompts. Headless means it can continue without someone watching each step.

In plain words
What is it for?
Use it to start a new sprint or resume an existing one through the plan, task, work, code-review, and commit stages. It requires the stated setup and a Git repository.
Why use it?
It lets a user leave the process running while the workflow makes conservative choices and records its progress in an audit log.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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

yolo 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 4d 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 — 312 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/magi:yolo — headless full-pipeline runner

You are the coordinator. The user has invoked /magi:yolo because they want the full pipeline executed without any prompts — they're walking away. Run plan → tasks → work → review-code → commit (and optionally push) in one shot. Never ask for user input after launch.

This skill is intentionally separate from the normal workflow. It violates the "顯式優先" design principle on purpose, scoped to opt-in use. Decisions that would normally pause for user confirmation are auto-resolved with the most conservative non-destructive default.

0. Preflight

PLUGIN_ROOT="${CLAUDE_PLUGIN_ROOT:-}"
[[ -z "$PLUGIN_ROOT" ]] && PLUGIN_ROOT="$(cd "$(dirname "$BASH_SOURCE[0]")/../.." 2>/dev/null && pwd)"
USER_CONFIG="$HOME/.config/magi-workflow/config.json"

If config missing → abort with "/magi:setup required".

Confirm we are inside a git repo:

git rev-parse --git-dir >/dev/null 2>&1 || { echo "not a git repo"; exit 1; }

0.5. State preflight (auto-refuse)

STATE_JSON=$(bash "$PLUGIN_ROOT/scripts/shared/detect-state.sh")
blocked=$(jq -r '.disallowed_skills["yolo"] // empty' <<<"$STATE_JSON")
if [[ -n "$blocked" ]]; then
  reason=$(jq -r '.disallowed_skills["yolo"].reason' <<<"$STATE_JSON")
  suggest=$(jq -r '.disallowed_skills["yolo"].suggest' <<<"$STATE_JSON")
  echo "Cannot run /magi:yolo: $reason"
  echo "Suggested: $suggest"
  exit 1
fi

Yolo is refused only in BOOTSTRAP (suggest /magi:init first).

0.6. Mode determination (fresh vs resume)

Yolo has two modes, mutually exclusive, determined by arguments:

Invocation Mode Behavior
/magi:yolo "<description>" Fresh Create new sprint, run full pipeline plan→...→commit
/magi:yolo --resume [--sprint <slug>] Resume Pick up an existing sprint (latest by default, or --sprint) from its current state, skipping phases already done
/magi:yolo (no description, no --resume) error Print usage hint and abort
/magi:yolo "<desc>" --resume error Mutually exclusive

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 is a skill published in the GitHub repository howar31/magi-workflow (2 stars, last pushed 5d ago), licensed MIT. It adds 117 tokens to every session and 3,610 once invoked, about $0.0006 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.
