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 | $0.00762 | $0.00762 |
| Opus 5.5 | $0.00305 | $0.00305 |
| Sonnet 5.5 | $0.00152 | $0.00152 |
| Haiku 4.5 | $0.00076 | $0.00076 |
Grade A, and why
pi-codemode 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.

pi-codemode Agent Instructions
Development approach: TDD first
All new behavior must be developed test-first.
- Write or update a focused failing test that describes the desired behavior.
- Run the relevant test command and confirm it fails for the expected reason.
- Implement the smallest change that can make the test pass.
- Run the test again and confirm it passes.
- Refactor only after tests are green.
- Repeat in small slices.
Do not add broad implementation before there is a failing test covering the behavior.
Test expectations
- Prefer small unit tests for executor, type generation, command quoting, config merging, and bridge behavior.
- Add integration tests for cross-component workflows only after the involved units are covered.
- For bug fixes, first add a regression test that fails on the current code.
- Tests should assert observable behavior, not implementation details, unless the detail is a security/resource-safety requirement.
Current MVP priority
The main MVP path is the QuickJS executor:
- QuickJS is the default executor target.
- Deno is optional/future and should stay behind the executor interface.
- Do not add a Node VM executor for MVP.
- Generated code should only access explicit globals:
codemode,$,shell,print, andπ. - Host tool calls must support async success, async failure, concurrency, timeout/cancellation, and clean runtime/context disposal.
Required QuickJS executor test slices
Before expanding executor features, keep these behaviors covered by tests:
- returns primitive and object values
- captures
print/ console output - injects
πstring constants - awaits one async host tool call
- resolves many concurrent host tool calls via
Promise.all - propagates rejected host calls to the guest promise
- supports nested MCP-style namespaces, e.g.
mcp.github.search_issues(...) - times out runaway code
- does not expose Node or host globals such as
process,require, filesystem, environment, network, or subprocess APIs - releases QuickJS runtime/context memory cleanly after execution
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-codemode AGENTS.md is an instructions file published in the GitHub repository boozedog/pi-codemode (27 stars, last pushed 1mo ago), licensed MIT. It adds 762 tokens to every session, about $0.0030 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.
