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 | $0.02407 | $0.02407 |
| Opus 5.5 | $0.00963 | $0.00963 |
| Sonnet 5.5 | $0.00481 | $0.00481 |
| Haiku 4.5 | $0.00241 | $0.00241 |
Grade A, and why
sekaisync AGENTS.md 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 14d 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 — 122 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repository Agent Guide
This is the single development guide for the connected SekaiSync workspaces. DSH, WinUI3 and UX root AGENTS.md files are reading pointers to this file, not separate policy copies. The members-only memories-of-melody repository is the shared knowledge base for Project OMNK's Project SEKAI-related projects; it owns the experience-library read/write protocol in its own AGENTS.md.
For agents answering Project Sekai questions through the product, use agents/rules/AGENTS.md; those are product query rules, not the development workflow.
Connected Workspaces
Resolve these five folders from the current project's configured paths before working across repositories. When present, read the ignored local path map at work/agent-context/connected-workspaces.local.json; it records checkout locations, not additional rules. Confirm that its destinations still exist before using it.

sekaisync-cli |
Backend and shared development workflow | This file |
dsh-sekaisync-connect |
DSH plugin | Pointer to this file |
sekaisync-winui3 |
Windows desktop client | Pointer to this file |
sekaisync-ux |
Shared UX/design workspace; temporarily non-public until complete | Pointer to this file |
memories-of-melody |
Shared knowledge base for Project OMNK's Project SEKAI-related projects; Project OMNK members only | Its own AGENTS.md read/write protocol |
The plugin and desktop submodules in this checkout are not additional connected repositories. Distinguish their pinned copies from the independent checkouts before editing. The official deepseek-harness upstream is a compatibility reference, not one of these five project folders.

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.

sekaisync AGENTS.md is an instructions file published in the GitHub repository omoinoki/sekaisync (23 stars, last pushed 11d ago), licensed MIT. It adds 2,407 tokens to every session, about $0.0096 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 2026-10-03.
