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 | $0.08147 | $0.08147 |
| Opus 5 | $0.04074 | $0.04074 |
| Sonnet 5 | $0.01629 | $0.01629 |
| Haiku 4.5 | $0.00815 | $0.00815 |
Grade A, and why
copilot-repo-template copilot-instructions.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 9d 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.

Repository Copilot Instructions (Repo-Wide Constitution)
Version: 1.6.20260629.0
Metadata
- Status: Active
- Owner: Repository Maintainers
- Last Updated: 2026-06-29
- Scope: Repo-wide canonical instructions ("constitution") that govern all changes in this repository. This file is the authoritative source of truth for repository rules; all language-specific instruction files and agent entry points defer to it.
- Related: Documentation Writing Style
These instructions are authoritative for all changes in this repository.
Source of Truth
Customize this section for your project. Point to your authoritative specification or design document. Example:
- Read
docs/spec/requirements.mdbefore making changes.- If any instruction here conflicts with the spec, the spec wins.
Protected Instruction Files
Instruction files and style guides are protected governance files. This rule applies to:
- The repo-wide constitution:
.github/copilot-instructions.md - Root agent entry points:
.hermes.md,AGENTS.md,CLAUDE.md, andGEMINI.md - Cursor project rules under
.cursor/rules/ - Modular instruction files under
.github/instructions/
Agents MUST NOT create, edit, delete, rename, or otherwise change protected instruction files unless the repository owner or maintainer has directly and explicitly authorized the specific instruction-file change in the current task. Implied consent is insufficient.
Authorization MUST NOT be inferred from:
- An agent-generated plan, rubric, option analysis, or implementation strategy.
- A request to fix code, resolve review feedback, update documentation as needed, or keep files in sync.
- Pre-commit, formatting, linting, validation, or other cleanup work.
- An automated review loop, reusable prompt, or generic permission to make repository changes.
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.
