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 | $0.00057 | $0.01571 |
| Opus 5 | $0.00028 | $0.00785 |
| Sonnet 5 | $0.00011 | $0.00314 |
| Haiku 4.5 | $0.00006 | $0.00157 |
Grade A, and why
relay 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 3d 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 — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Relay
Pass the baton to the next Sutando session. Where session-handoff.sh writes structured facts (recent commits, open PRs, pending Qs), /relay writes the narrative continuity — what you were just working on, what should be checked first, what might break and how to detect it.
Usage: /relay (writes a new relay file) or /relay --append (appends to the most recent unprocessed relay file rather than creating a new one).
Why this exists
src/session-handoff.sh pulls together the structured state for the next session — system status, recent commits, open PRs, pending questions, tasks, conversation tail, quota, repo stats — and writes it to session-state.md. But "I was about to land PR #X and Mini's review said Y matters most" isn't captured by git log, gh pr list, or pending-questions.md tail. The next session reads structured facts but has to RE-INFER the continuity, which costs context and frequently misses the load-bearing decision.
The relay note encodes intent + judgment — the thing only the LLM that lived through the session can write.
Folder layout
Mirrors Sutando's existing tasks/ and results/ convention:
workspace/relay/
├── relay-{epoch_seconds}.md # pending relay notes (drained into session-state.md, then archived)
└── processed/
└── relay-{epoch_seconds}.md # already drained; kept for audit
- File naming:
relay-{epoch}.md— sortable + greppable, matches thetask-{epoch}.txtshape. - Multiple files allowed:
/relayalways creates a NEW file by default.--appendappends to the LATEST unprocessedrelay-*.mdinstead of creating a new one. - Consumption:
src/session-handoff.shreads ALL unprocessedrelay-*.mdfiles in sorted order, appends them tosession-state.mdunder## Relay Notes (from prior sessions), thenmvs each one toprocessed/— but only after confirming its### <basename>header landed in the written file, so an interrupt cannot retire an uncaptured note. - Cleanup: kept indefinitely on local disk. Tiny files (~200-500 bytes each); a year of relay notes is < 1 MB. Sync via the workspace-sync engine (
scripts/sync-workspace.sh) for fleet visibility — the legacysync-memory.shflow is deprecated in v0.3.0 and removed in v0.4.0.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

relay is a skill published in the GitHub repository sonichi/sutando (390 stars, last pushed today), licensed MIT. It adds 57 tokens to every session and 1,571 once invoked, about $0.0003 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.
