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 | $0.02448 | $0.02448 |
| Opus 5 | $0.01224 | $0.01224 |
| Sonnet 5 | $0.00490 | $0.00490 |
| Haiku 4.5 | $0.00245 | $0.00245 |
Grade A, and why
pi-permission-modes 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 10d 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

Summary
A pi extension that implements Claude-Code-style permission modes (ask / plan / auto / bypass) for the pi coding agent, published on npm as @georgedong32/[email protected]. It intercepts tool calls, gates approvals per mode, supports CC-compatible allow/deny/ask permission rules (global + per-project), injects minimal mode context via a system-prompt anchor, provides an adaptive live footer, guards reads outside cwd in ask mode, supports an optional built-in auto classifier (completeSimple via @earendil-works/pi-ai/compat + ctx.modelRegistry auth), auto-switches the model per mode when the user has defined profiles in ~/.pi/agent/model-profiles.json, tracks outside-cwd writes for undo (bypass mode), and supports per-mode skill filtering.

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.

pi-permission-modes AGENTS.md is an instructions file published in the GitHub repository GeorgeDong32/pi-permission-modes (2 stars, last pushed 4d ago), licensed MIT. It adds 2,448 tokens to every session, about $0.0122 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 2026-08-31.
