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 | $0.14809 | $0.14809 |
| Opus 5.5 | $0.05924 | $0.05924 |
| Sonnet 5.5 | $0.02962 | $0.02962 |
| Haiku 4.5 | $0.01481 | $0.01481 |
Grade A, and why
copilot-repo-template python.instructions.md scanned grade A with 2 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 1mo 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.

Python Writing Style
Version: 1.10.20260910.0
Metadata
- Status: Active
- Owner: Repository Maintainers
- Last Updated: 2026-09-10
- Scope: Defines Python coding standards for all Python files in this repository, including modules, scripts, tests, and tooling. Covers style, structure, error handling, testing, and documentation requirements.
- Related: Repository Copilot Instructions
Purpose and Scope
This guide establishes the Python coding standards for the repository. Code MUST be maintainable, deterministic, and security-conscious. The style adapts to project constraints: stdlib-first, portability-first by default, shifting to modern-advanced when required by the technology stack (async frameworks, type-heavy APIs, etc.).
Note: This document uses RFC 2119 keywords (MUST, MUST NOT, SHOULD, SHOULD NOT, MAY) to indicate requirement levels.
Executive Summary: Author Profile
The default style is a highly disciplined stdlib-first, portability-first approach. When code can reasonably run on a minimal, widely available Python baseline, it SHOULD: minimize dependencies, avoid unnecessary metaprogramming, and prefer clarity over cleverness.
This baseline is not dogma. When external constraints require modern Python (e.g., typing-heavy APIs, async I/O, Pydantic models, FastAPI), the style intentionally shifts to a modern-advanced posture.
Quick Reference Checklist
Layout and Formatting
- [All] MUST use 4 spaces; never tabs.
- [All] MUST follow PEP 8/PEP 257; line length target <= 100 (MAY exceed for URLs/long strings when readability wins).
- [All] MUST keep formatting tool-friendly: MUST NOT hand-align with extra whitespace.
- [All] SHOULD use f-strings for interpolation; SHOULD NOT use
%or.format()formatting except when required. - [All] SHOULD NOT rely on same-line implicit concatenation of adjacent string literals such as
f"a " "b"or"a" "b", and SHOULD NOT mix an f-string with an adjacent plain literal on the same line; a missing comma silently concatenates instead of erroring. Prefer one f-string or plain literal, and reserve adjacency for intentional multi-line wrapping described below. - [All] MUST NOT include trailing whitespace; files MUST end with a single newline.
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.

copilot-repo-template python.instructions.md is an instructions file published in the GitHub repository franklesniak/copilot-repo-template (9 stars, last pushed 5d ago), licensed MIT. It adds 14,809 tokens to every session, about $0.0592 per session on Opus 5.5. A static security scan graded it A with 2 findings (makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
