string-le: Instructions file for Codex

AGENTS.md

string-le AGENTS.md is an instructions file for Codex, OpenCode from nolindnaidoo/string-le. It costs 8,165 tokens per session, scanned A, a copy of regex-le AGENTS.md, MIT.

A repository instruction document for Strings-LE, a VS Code extension and Rust command-line tool that extract text values from files. It explains the architecture, shared test data, and rules contributors and coding agents must follow.

In plain words
What is it for?
Use it when changing the project to understand its two products, supported file formats, shared extraction behavior, architecture boundaries, and required verification scripts.
Why use it?
It provides the technical source of truth and helps keep the extension and command-line tool consistent, including checks that compare their results.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions AGENTS.md.

This is nolindnaidoo/string-le's own configuration. It tells Codex and OpenCode how to work on string-le itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything string-le configures →

What it costs to keep this loaded

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.

Security

Grade A, and why

string-le AGENTS.md scanned grade A with 1 finding 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 3d 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.

AGENTS.md — Strings-LE

Technical source of truth for this repo. README.md is the user-facing doc; this file is for anyone (human or agent) changing the code.

This repo hosts two products: the extension at the root (this document's scope) and the Rust CLI in crate/ (its own AGENTS.md + SPEC.md). The shared extraction corpus lives at crate/fixtures/; scripts/check-extraction-parity.ts fails CI when this extension drifts from it.

scripts/check-differential.ts is the second half of that guard: it drives the shared extract_strings MCP tool on both servers — this one and the crate's — over generated documents, and requires byte-identical answers. The corpus pins the cases somebody thought of; that pins the ones nobody did. Scope is the shared tool only. The two surfaces are meant to differ — this one is IDE-first, for one open buffer; the CLI is terminal-first, for trees, exit codes and pipes — so the walk, --strict, --values and --multiline are the crate's alone and are never held against this side.

The Rust CLI also ships a second way, through npm: src/cli/ is its terminal surface rebuilt over this extension's extraction engine, bundled to cli/cli.js as the npm package strings-le (npm refuses string-le as too close to an older stringle). Both install a command named string-le, so the npm one is held to the crate's surface byte for byte, which is a different contract from the extraction parity above. src/cli/ follows crate/src/cli.rs, scan.rs, walk.rs, extract/locate.rs, extract/position.rs and mcp/mod.rs, not the extension's commands, and scripts/check-cli-parity.ts runs both binaries over one generated tree and fails on any difference in stdout, stderr or exit code, and in what string-le mcp answers. The one thing it does not compare is the wording after Invalid <FORMAT>: when a parser refuses a document, which crate/SPEC.md already lists as a deliberate difference. scripts/check-cli-pipes.ts, shared with every port, closes stdout or stderr before either binary writes and fails on any difference in what follows, on all three operating systems. A change to the crate's surface changes src/cli/ in the same commit.
