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 | $0.00628 | $0.00628 |
| Opus 5.5 | $0.00251 | $0.00251 |
| Sonnet 5.5 | $0.00126 | $0.00126 |
| Haiku 4.5 | $0.00063 | $0.00063 |
Grade A, and why
pie 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.
How it starts
The opening of the file, as written. The whole thing — 37 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repository Guidelines
Project Structure & Module Organization
This repository is a Rust 2024 Cargo workspace. The root Cargo.toml lists three members:
crates/ai:pie-ai, the unified streaming LLM client, provider integrations, OAuth helpers, model catalogs, and utilities.crates/agent:pie-agent-core, the agent runtime, harness, session storage, skills loading, compaction, and lifecycle hooks.crates/coding-agent:pie-coding-agent, thepieCLI binary, REPL TUI, tools, config, and session handling.
Each crate keeps implementation in src/, integration tests in tests/, and runnable examples in examples/ where present. Provider model data and generated Rust live under crates/ai/src/; use crates/ai/scripts/regen_models.sh when regenerating model catalogs.
Build, Test, and Development Commands
cargo build --workspace: build all workspace crates.cargo build --release: produce the optimizedtarget/release/pieCLI.cargo test --workspace: run all crate tests.cargo clippy --workspace --all-targets -- -D warnings: lint libraries, binaries, tests, and examples with warnings as errors.cargo fmt --all --check: verify Rust formatting../target/release/pie --help: inspect CLI flags after a release build.
Coding Style & Naming Conventions
Use standard rustfmt formatting and Rust 2024 idioms. Keep module and file names in snake_case; public types and traits in PascalCase; functions, variables, and test names in snake_case. Prefer crate-local patterns and shared workspace dependencies before adding new dependencies. Keep provider-specific code under crates/ai/src/providers/ and CLI tools under crates/coding-agent/src/tools/.
Testing Guidelines
Place integration tests in the relevant crate’s tests/ directory and keep unit tests close to the code they exercise. Tests should avoid real network calls unless explicitly gated; CI clears provider API-key environment variables to catch accidental live calls. Before opening a PR, run cargo test --workspace, cargo clippy --workspace --all-targets -- -D warnings, and cargo fmt --all --check.
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.

pie AGENTS.md is an instructions file published in the GitHub repository c4pt0r/pie (173 stars, last pushed 3mo ago), licensed MIT. It adds 628 tokens to every session, about $0.0025 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.
