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 | $0.02927 | $0.02927 |
| Opus 5.5 | $0.01171 | $0.01171 |
| Sonnet 5.5 | $0.00585 | $0.00585 |
| Haiku 4.5 | $0.00293 | $0.00293 |
Grade A, and why
Nyamu 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 2mo 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.

About MCP
- This project uses the Nyamu MCP server, which enables triggering compilations and retrieving compilation errors from the Unity Editor.
- Iterate through the edit-compile-debug cycle until all errors are resolved.
Nyamu MCP Workflow Guidelines
File Operation Workflows
CRITICAL: Always call assets_refresh after file operations - it returns compilation error information:
- Creating files: Write →
assets_refresh(force=false)→ Wait for MCP (response includes compilation errors) - Deleting files: Delete →
assets_refresh(force=true)→ Wait for MCP (response includes compilation errors) - Editing existing files: Edit →
scripts_compile(no refresh needed)
Compilation Tools
assets_refresh- PRIMARY COMPILATION CHECK TOOL (params: force, default false)- Main command to check compilation status after any file operations
- Returns compilation error information, showing last compilation status even if no new compilation occurred
- Unified tool: asset refresh + compilation trigger + status check in one command
- Use force=true when deleting files to prevent CS2001 errors
- Use force=false when creating/editing files
- No need to call scripts_compile_status separately - this tool provides all compilation information
scripts_compile- Direct C# compilation trigger (params: timeout, default 30s)- Use for editing existing files without structural changes (faster than assets_refresh)
scripts_compile_status- Check compilation status without triggering (no params)- Use only when you need status check without any file operations
Error Handling
- Error -32603 "HTTP request failed": Expected during Unity recompilation/refresh
- Wait 3-5 seconds and retry
- This is normal behavior - Unity HTTP server is restarting
- Always wait for MCP responsiveness after
assets_refreshbefore calling other tools
Testing Tools
Available test execution tools:
tests_run_all- Run all tests (params: test_mode, timeout)tests_run_single- Run specific test (params: test_name required, test_mode, timeout)tests_run_regex- Run tests matching regex (params: test_filter_regex required, test_mode, timeout)tests_run_status- Check test execution status (no params)tests_run_cancel- Cancel running tests (params: test_run_guid optional)
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.

Nyamu AGENTS.md is an instructions file published in the GitHub repository polyblank66/Nyamu (15 stars, last pushed 2mo ago), licensed MIT. It adds 2,927 tokens to every session, about $0.0117 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 2026-08-30.
