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 | $0.00049 | $0.01274 |
| Opus 5.5 | $0.00020 | $0.00510 |
| Sonnet 5.5 | $0.00010 | $0.00255 |
| Haiku 4.5 | $0.00005 | $0.00127 |
Grade A, and why
handoff 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 2d 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 — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Handoff
Write a session handoff file at .turbo/handoff/<YYYY-MM-DD>-<slug>.md so a fresh session can pick up where this one left off.
Step 1: Resolve the Target Path
Get today's date: date +%Y-%m-%d.
Pick a slug for the current task:
- Lowercase
- Replace non-alphanumeric characters with hyphens
- Collapse consecutive hyphens
- Trim leading and trailing hyphens
- Truncate to 40 characters at a word boundary
If the work is anchored to an existing plan at .turbo/plans/<slug>.md, reuse that plan's slug verbatim.
The user may pass an explicit slug or output path; honor it.
Resolve the repo root with git rev-parse --show-toplevel, except inside a linked worktree — where git rev-parse --git-dir differs from --git-common-dir — in which case use the parent of the common dir, so the handoff lands in the main checkout rather than in a worktree that is destroyed with its branch.
The target path is .turbo/handoff/<YYYY-MM-DD>-<slug>.md under that root. A generated slug takes -2, -3, and so on until the path is free. When the user supplied the slug or path and it already exists, use AskUserQuestion to offer overwrite, a numeric suffix, or a different slug.
When an open decision will outlive the rest of the session's state, still unresolved while the work around it is finished, give it its own handoff. Everything else stays in a single file. Slug the split handoff for that decision rather than appending a collision suffix, and write it to stand alone.
State the chosen path before continuing.
Step 2: Gather Session State
Run git status --short to see uncommitted changes in the working tree.
Survey the conversation context for:
- Current task: what is being worked on, in one or two sentences
- Workflow status: where in the workflow this session is (drafting, refining iteration N, applying findings, implementing step M of K, investigating, blocked on Q, etc.)
- Active artifact: path to the plan or other file at the center of the work, if one exists
- Open decisions: questions raised but not resolved, choices the user is still weighing, escalations awaiting input, actions only the user can take
- In-flight changes: staged or unstaged edits that are not yet committed; what each change is doing and what is missing
- Closed avenues: approaches that were built or tested and then abandoned, with the observed evidence that ruled them out
- Next step: the first concrete action the new session should take. When the user has stated what they want to work on next, that intent leads and any work left in flight is ordered after it; say so in the same statement when that work should not resume at all
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.

handoff is a skill published in the GitHub repository tobihagemann/turbo (420 stars, last pushed today), licensed MIT. It adds 49 tokens to every session and 1,274 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-11-09.
