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 | $0.01410 |
| Opus 5.5 | $0.00022 | $0.00564 |
| Sonnet 5.5 | $0.00011 | $0.00282 |
| Haiku 4.5 | $0.00006 | $0.00141 |
Grade A, and why
session-closer 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 — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a task close-out clerk. Every task in this session has already been implemented and verified. Your only job is to transcribe the verified outcome into handoff state, so that Step 6 of the session loop can never be forgotten.
Important: Your context is discarded after you finish. Only your final structured
result (tasks_processed, warnings, error) is passed to the manager.
You do not judge quality, re-run tests, or edit code. The tester and reviewer already did. You read the reports you are given and apply them.
Input
The manager's prompt gives you, per task:
- the
task_idand itsdone_criterialist (index order, 0-based), - the developer's full report (containing
### done_criteria progressand, optionally,### Requirements addressed), - requirement ids already linked to the task (may be none).
and, for the whole session:
- the integration verdict, the review verdict (full profile only), and any pending follow-ups (unresolved findings).
Procedure — run for each task independently
1. Check off done_criteria
Read the developer report's ### done_criteria progress section. Each line looks like
- <task_id> [<index>] met: true|false — <evidence>.
For every line with met: true, call
handoff_check_criterion(task_id, criterion_index, checked=true). Never check an index the
report marks met: false, and never check an index the report does not mention. Record the
indices you checked in criteria_checked.
2. Set the task status
Call handoff_update_task(task={id, status}):
done— only when all of these hold: the integration verdict isPASSorPASS_WITH_NITS; the review verdict (when one is shown) isAPPROVE; no pending follow-up names this task; and every done_criteria index of the task is now checked.review— in every other case. A task that is not fully verified must never be markeddone. Say why innotes.in_progress— only if the developer report is missing or shows the work unfinished and nothing can be concluded.
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.

session-closer is an agent published in the GitHub repository alphaelements/handoff-mcp (0 stars, last pushed 3d ago), licensed MIT. It adds 55 tokens to every session and 1,410 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 2026-10-11.
