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 | $0.00412 | $0.00412 |
| Opus 5 | $0.00206 | $0.00206 |
| Sonnet 5 | $0.00082 | $0.00082 |
| Haiku 4.5 | $0.00041 | $0.00041 |
Grade A, and why
regex-le 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 6d 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.

What it actually says
Contributor and agent instructions
Read AGENTS.md before writing any code. It carries the engineering standard this repository is held to — control flow, error handling, immutability, structure — plus the architecture, the invariants and why each one exists. CLAUDE.md is the short version: gates and traps.
This file exists only to route you there. It is deliberately thin: the standard lives in one place so it cannot drift between tools.
Non-negotiables
- Guard clauses first. No
else, noelse if— two branches are an early return, many are a lookup table. - Nesting stops at two levels inside a function.
- Immutable by default:
readonly,ReadonlyArray,Object.freeze. Never mutate a parameter. - Composition, never inheritance. Factory functions returning frozen objects, dependencies passed in as a typed bag.
- Logic never touches
vscode.window.*;ui/renders andcommands/orchestrates. - Never report success you did not achieve — check what the API returned.
- Errors are descriptive and never swallowed.
- Comments explain why, never what.
- Commits are conventional (
fix:,feat:,docs:…), imperative, and enforced by a hook and by CI.
Before you commit
bun run typecheck && bun run lint && bun run test
Coverage floors are a backstop against an untested module, not a target: they sit well below where the code actually is and are never raised to track it. Every claim in a README or manifest must be provable against the code.
Provable is about behaviour and numbers, not availability. An install line for a release you are about to make is staged, not forbidden — write it, and let the release commit be what makes it true.
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.

regex-le copilot-instructions.md is an instructions file published in the GitHub repository nolindnaidoo/regex-le (2 stars, last pushed 4d ago), licensed MIT. It adds 412 tokens to every session, about $0.0021 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.
