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 | $0.00304 | $0.00304 |
| Opus 5 | $0.00152 | $0.00152 |
| Sonnet 5 | $0.00061 | $0.00061 |
| Haiku 4.5 | $0.00030 | $0.00030 |
Grade A, and why
agent-public 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 7d 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
Agent Protocol
- Guardrails: use
trashfor deletes when available. - Commits: Conventional Commits (
feat|fix|refactor|build|ci|chore|docs|style|perf|test). - Web: search early; quote exact errors; prefer 2025-2026 sources.
- Style: telegraph. Drop filler/grammar. Min tokens. When reporting information to user, be extremely concise and sacrifice grammar for the sake of concision.
Tools
Python Executable
- Use
python3for all Python execution.
Serena MCP
MANDATORY for all code (not markdown) navigation. Token economy is critical — every unnecessary file read burns context budget.
- Use Serena only for files inside the current project directory/root.
- Do not use Serena for paths outside
$cwd/ active project root; it is project-scoped and will deny external access. - For anything outside current project dir, use standard tools (
read,bash,write,edit) instead of Serena.
Editing (symbol-level precision; no broad rewrites)
- Replace function/method/class body →
serena_replace_symbol_body. - Add new code adjacent to existing symbol →
serena_insert_after_symbol/serena_insert_before_symbol. - Rename across codebase →
serena_rename_symbol.

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.
