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 | $0.00045 | $0.00362 |
| Opus 5 | $0.00023 | $0.00181 |
| Sonnet 5 | $0.00009 | $0.00072 |
| Haiku 4.5 | $0.00005 | $0.00036 |
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.
What it actually says
Session Handoff
Prepare context for the next session so work can continue seamlessly.
Process
-
Review active tasks — call
task_listwith filter+ACTIVEto find tasks that were being worked on. Use the UUIDs from that response for the calls below; do not rely on UUIDs you remember from earlier in the session. For each task in the result:- Use
task_annotateto record what was accomplished and what remains - Use
task_stopto mark it as no longer active
- Use
-
Review pending tasks — call
task_listwith filterstatus:pendingto see the full backlog. Note any tasks whose status has changed based on work done this session. -
Log unplanned work — if work was done that wasn't tracked as a task, use
task_logto record it retroactively with appropriate project and tags. -
Update blocked tasks — if any blockers were resolved this session, use
task_modifyto remove dependencies or update descriptions. -
Present the handoff summary:
- Done this session: tasks completed or logged
- Progress made: annotations added to in-progress tasks
- Ready to pick up next: pending tasks sorted by priority that aren't blocked
- Blockers: any tasks that are blocked and why
Keep the summary concise — the goal is to give the next session (or agent) a clear starting point.
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 backloghq/backlog (5 stars, last pushed 3mo ago), licensed MIT. It adds 45 tokens to every session and 362 once invoked, about $0.0002 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.
