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 | $0.01976 | $0.01976 |
| Opus 5.5 | $0.00790 | $0.00790 |
| Sonnet 5.5 | $0.00395 | $0.00395 |
| Haiku 4.5 | $0.00198 | $0.00198 |
Grade A, and why
fonline-tla 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 13d 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 — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
FOnline: The Life After — Agent Instructions
Read this project guide fully, then the task's owning documents. Human entry:
README.md; full index: Docs/README.md.
.github/copilot-instructions.md points here; do not maintain competing
instruction bodies.
Start and authority
- Confirm checkout, branch, requested outcome and dirty files. Inspect the project
and
Engine/independently; preserve user and other-agent edits. Re-anchor from the plan, current source and diff after a handoff or compaction. - Read owners, validators and callers before designing a change. Requirements establish intended behavior; source establishes current behavior. Historical logs, summaries and worker reports are evidence, not new action authority.
- Carry the authorized scope through implementation and verification. Resolve routine choices from source; ask for material missing requirements or actions outside scope. If a required source is unavailable, report it and wait before synthesizing conclusions.
- Before non-trivial implementation, write a plan in
Docs/Plans/, including plans produced by workflow skills. Update its scope, steps, decisions, acceptance and actual verification results as work proceeds. Update affected documentation alongside the changes; do not defer plans or docs to the final handoff. Follow the working procedure. - Put private task logs, screenshots, scripts, dumps, drafts and worker inputs in ignored
Workspace/<task-id>/. Standard tool outputs keep their owning paths; permanent delegation history follows the governing launcher procedure. Maintained guides belong underDocs/; keep task reports out of the repository root.
- No
git add, commit, push, merge, destructive Git operation, publication or deployment without explicit action authority. Prepare reviewable local edits; “prepare for commit” does not mean create a commit. Past permissions do not authorize a new task. Never revert work you did not make. - Stay on the requested project branch/worktree. Engine-only branch/history
instructions apply only to Engine. Normal Engine updates keep its
masterbranch; do not detach or move the project branch incidentally. - Chat with the owner in Russian unless requested otherwise. General project/
agent docs and native C++ stay English; keep existing documents in their own
language (
Docs/ScriptStyle.mdis Russian). Script comments and module headers are Russian; translate existing English comments when touching the module. Serialized metadata, IDs, text keys and identifiers stay English. - Do not read credentials for unrelated maintenance or copy secrets/raw private sessions into source, chat or reports. The base config's public development channel pair is for local use; production keys remain host-owned.
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.
