personal_kb: Instructions file for GitHub Copilot

.github/copilot-instructions.md

personal_kb copilot-instructions.md is an instructions file for GitHub Copilot from haxudev/personal_kb. It costs 261 tokens per session, scanned A, original, MIT.

Repository instructions for a personal knowledge base that turns files into searchable Markdown notes. Its two main slash commands are /ingest for importing files and /query for searching the resulting notes.

In plain words
What is it for?
Use them when importing files, searching the knowledge base, reporting file-based results, or deciding when Microsoft Learn access is needed.
Why use it?
They define the path from incoming files to searchable content and require truthful results when nothing is found. They also ensure suggested commands match the user's operating system.

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

personal_kb 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 2mo 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

Copilot CLI Instructions for Personal KB

This repository uses slash-command-oriented skills for Copilot CLI. The primary user entry points are:

  1. /ingest — Convert files from inbox/ to searchable Markdown in workmemory/
  2. /query <keywords> — Search workmemory/ using ripgrep

Workflow

  1. User places files in inbox/
  2. User runs /ingest to convert them
  3. User runs /query to search their knowledge base
  4. You present results with file paths and context

Important

  • Never fabricate content. If search returns nothing, say so.
  • Always check workmemory/ before claiming no results — suggest /ingest if it's empty.
  • Use the example MCP configuration in tools/mcp.example.json, merged into ~/.copilot/mcp-config.json, to access Microsoft Learn when local results are insufficient.

Command execution preference

  • Detect the user execution environment before suggesting commands.
  • If the user is on Windows, prefer Windows CMD / PowerShell command syntax first for both /ingest and /query.
  • Only default to POSIX shell syntax for macOS, Linux, or WSL contexts.

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.
