rosetta: Instructions file for GitHub Copilot

.github/instructions/query-core-not-adapter.instructions.md

rosetta query-core-not-adapter.instructions.md is an instructions file for GitHub Copilot from tikoci/rosetta. It costs 152 tokens per session, scanned A, original, MIT.

A rule for placing shared search and retrieval behavior in the common query code. MCP and browse are two interfaces that should receive the same underlying results.

In plain words
What is it for?
Use it when deciding whether a query heuristic belongs in src/query.ts, mcp.ts, browse.ts, or a shared helper.
Why use it?
It prevents one interface from gaining a heuristic that the others do not have. It also keeps adapters focused on transport, formatting, and user-interface details.

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 query-core-not-adapter.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.

What it actually says

Query core, not adapter

Default to landing behavior in shared query logic.

  • If a heuristic can help both MCP and browse, put it in src/query.ts (or a shared pure helper), not only in mcp.ts or browse.ts.
  • Treat MCP-only or TUI-only heuristics as a smell unless the surface truly has unique needs.
  • Keep adapters thin: formatting, transport wiring, and UI affordances belong there; retrieval logic usually does not.
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.
