Why use it?
It prevents different parts of the project from using conflicting database settings or table assumptions.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is tikoci/rosetta's own configuration. It tells GitHub Copilot how to work on rosetta 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 rosetta configures →

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

rosetta database.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 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.

How it starts

The opening of the file, as written. The whole thing — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Database Layer

Key Rules

  • Use bun:sqlite — never better-sqlite3 or other drivers
  • WAL mode + foreign keys enabled in initDb()
  • DB_PATH env var overrides default ros-help.db
  • Singleton pattern: one Database instance shared across modules

Tables

  • pages + pages_fts — legacy Confluence HTML pages (breadcrumb path, URL, text, code); do not assume this identity model works for the future Docusaurus extractor
  • callouts + callouts_fts — Note/Warning/Info/Tip callouts (FK → pages)
  • sections — page sections split by h1–h3 headings with anchor IDs (FK → pages)
  • page_tables + page_table_rows + page_table_cells — normalized Docusaurus pipe tables with raw Markdown, page/section provenance, and actual ragged row widths
  • properties + properties_fts — Docusaurus table/bullet properties plus historical Confluence properties (FK → pages; table-derived rows link to page_table_rows)
  • commands — command tree entries from inspect.json (FK → pages for linked dirs)
  • ros_versions — tracked RouterOS versions with channel metadata
  • command_versions — junction: command_path × ros_version (full extracted history)
  • schema_nodes + schema_node_presence — multi-arch deep-inspect schema; presence is pruned to active channel heads in release DBs
  • devices + devices_fts — MikroTik products with hardware specs (from product matrix CSV)
  • device_test_results — benchmark rows per device (ethernet/IPSec throughput)
  • changelogs + changelogs_fts — parsed per-entry changelog data (version, category, breaking flag)
  • videos + videos_fts — MikroTik YouTube video metadata
  • video_segments + video_segments_fts — chapter-level transcript segments (FK → videos.id)
  • dude_pages + dude_pages_fts — archived Dude wiki pages from Wayback/cache
  • dude_images — screenshot metadata for Dude wiki pages
  • skills + skills_fts — RouterOS agent skill guides from tikoci/routeros-skills
  • skill_references — reference documents attached to skills
  • glossary — seeded RouterOS terms and aliases
  • db_meta — release provenance and schema/update metadata

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.
