Token cost

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

DialectOS 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 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.

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.

AGENTS.md — DialectOS

Agent-focused guidance for the DialectOS Spanish dialect translation system.

Public Agent Skill

  • skills/dialectos/SKILL.md is the public skill for this repo.
  • Invoke $dialectos in compatible agent hosts for regional Spanish localization, markdown/API-doc preservation, locale JSON validation, glossary enforcement, formality checks, gender-neutral language, and launch certification.
  • Keep the skill aligned with packages/cli/README.md, packages/mcp/README.md, provider setup, and certification commands when those surfaces change.

Project Structure

pnpm monorepo with 7 workspace packages under packages/:

Package Role Key exports
@dialectos/types Types, schemas, dictionary data SpanishDialect, DICTIONARY, VERB_CONJUGATIONS
@dialectos/security Rate limiting, path validation, error sanitization RateLimiter, validateFilePath
@dialectos/locale-utils Locale file read/write, flatten, diff readLocaleFile, writeLocaleFile, diffLocales
@dialectos/markdown-parser Markdown structure preservation parseMarkdown, reconstructMarkdown
@dialectos/providers Translation providers + post-processing LLMProvider, createProviderRegistry, BulkTranslationEngine
@dialectos/cli CLI commands, evaluation scripts, web demo dialectos binary
@dialectos/mcp MCP server for IDE integration createServer

Scripts in scripts/ are thin Node CLIs that import from packages/cli/dist/.

Build

pnpm install
pnpm build        # tsc for all 7 packages
pnpm test         # vitest across all packages + static checks

Important: Scripts that import from dist/ will auto-trigger pnpm build if dist is missing (via scripts/lib/ensure-built.mjs).

Testing

  • Unit tests: vitest per package
  • Script integration tests: spawn actual child processes (slow — 5+ min for full CLI suite)
  • Static checks: node --test docs/__tests__/*.test.mjs scripts/__tests__/*.test.mjs

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.
