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 | $0.00021 | $0.00358 |
| Opus 5 | $0.00010 | $0.00179 |
| Sonnet 5 | $0.00004 | $0.00072 |
| Haiku 4.5 | $0.00002 | $0.00036 |
Grade A, and why
vault-checkin 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 9d 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
Log what the user worked on today.
Identify Who
Look for indicators: "@brett", "@brandon", name mentions, or context clues.
If unclear, use ask_user to confirm.
Parse Input
Extract:
- Work items: Things accomplished or worked on
- Blockers: Anything preventing progress (optional)
- Notes: Additional context or thoughts (optional)
Create Check-in
vault_create_entry(entry_type: "checkin", entry_date: "{today}", author: "{person}", ...)
Content should include work items as a bulleted list, blockers section, and notes section.
If a checkin already exists for this person today, use vault_update_entry to append.
Match to Kanban
For each work item that sounds like a completion:
vault_kanban(action: "search", search_term: "{work_item}")to find matching tasks- If a match has high confidence (similarity > 0.5), offer to mark complete
- If uncertain, use
ask_user: "Is '{work item}' the same as '{kanban task}'?" - Complete confirmed matches:
vault_kanban(action: "complete", task_id: "...")
Refresh
vault_dashboard(dashboard_type: "activity") to update the dashboard.
Report: checkin file created, work items recorded, kanban matches found/completed.
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.

vault-checkin is a skill published in the GitHub repository pass-agent/loomkin (179 stars, last pushed 3mo ago), licensed MIT. It adds 21 tokens to every session and 358 once invoked, about $0.0001 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.
