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 | $0.00093 | $0.01555 |
| Opus 5 | $0.00046 | $0.00777 |
| Sonnet 5 | $0.00019 | $0.00311 |
| Haiku 4.5 | $0.00009 | $0.00155 |
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 — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Writing the end-of-session handoff
The doctrine
Fix first, hand off the remainder. A handoff entry is a failure this session did not cause and could not fix on this branch. A failure your own diff caused is yours. A clean session writes nothing and says nothing — never "no handoff needed".
An intermittent test failure is not a handoff item. The ci-triage skill owns it, including the rule that hardware you lack is never an exit. Two flakes still hand back, one line each: one an OPEN PR already covers (name that PR), and one blocked by a credential you lack that stops you from committing a runnable reproduction at all (name the credential).
The four steps
- Fix what you can reach. Work every item on this branch until only the unreachable remain. Needing another PR is not a reason to defer — open it.
- Earn "pre-existing". Reproduce the failure on the unmodified base before you call it unrelated:
Then run the exact failing command there and quote what it printed. A claim you did not run is a hypothesis, and it says so. Reproducing it on the base earns "pre-existing", never "not mine": a red base blocks every branch, so the fix rides the PR you already have open. Mergeumask 022 && git worktree add --detach /tmp/claude-worktrees/base origin/mainorigin/maininto your branch and run it again before you hand anything back — a failure only that merge produces is yours however green both sides are alone. - Deduplicate. Search issues and pull requests, because a multi-PR effort is tracked by an issue that no PR search finds:
mcp__github__search_issuesandmcp__github__search_pull_requests, both withowner/repoandfields: ["number","state","title"].gh pr list --searchis GraphQL and answers 403 in a web session, so the MCP tools are the only route that works on both surfaces.- An
OPENtracking issue owns the item: add your row by EDITING that issue, and file no second one. - Read the PR state:
OPENgets one line naming it and no fresh investigation;MERGEDmeansmainalready carries the fix, so drop the item;CLOSEDcovers nothing, so the item stands.
- Paste it in chat, in full. Never a bare file path: on the host the reader has no shell to open one, and inside the sandbox
/tmpdies at teardown. Commit a copy only when it is worth keeping.
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 AlexanderMattTurner/agent-glovebox (62 stars, last pushed today), licensed Apache-2.0. It adds 93 tokens to every session and 1,555 once invoked, about $0.0005 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 2026-08-30.
