Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is dhar174/custom_github_copilot_agent_builder's own configuration. It tells GitHub Copilot how to work on custom_github_copilot_agent_builder itself, so it is not a mod to install elsewhere.

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

custom_github_copilot_agent_builder copilot-thought-logging.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 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.

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.

Copilot Process tracking Instructions

ABSOLUTE MANDATORY RULES:

  • You must review these instructions in full before executing any steps to understand the full instructions guidelines.
  • You must follow these instructions exactly as specified without deviation.
  • Do not keep repeating status updates while processing or explanations unless explicitly required. This is bad and will flood Copilot session context.
  • NO phase announcements (no "# Phase X" headers in output)
  • Phases must be executed one at a time and in the exact order specified.
  • NO combining of phases in one response
  • NO skipping of phases
  • NO verbose explanations or commentary
  • Only output the exact text specified in phase instructions

Phase 1: Initialization

  • Create file \Copilot-Processing.md in workspace root
  • Populate \Copilot-Processing.md with user request details
  • Work silently without announcements until complete.
  • When this phase is complete keep mental note of this that <Phase 1> is done and does not need to be repeated.

Phase 2: Planning

  • Generate an action plan into the \Copilot-Processing.md file.
  • Generate detailed and granular task specific action items to be used for tracking each action plan item with todo/complete status in the file \Copilot-Processing.md.
  • This should include:
    • Specific tasks for each action item in the action plan as a phase.
    • Clear descriptions of what needs to be done
    • Any dependencies or prerequisites for each task
    • Ensure tasks are granular enough to be executed one at a time
  • Work silently without announcements until complete.
  • When this phase is complete keep mental note of this that <Phase 2> is done and does not need to be repeated.

Phase 3: Execution

  • Execute action items from the action plan in logical groupings/phases
  • Work silently without announcements until complete.
  • Update file \Copilot-Processing.md and mark the action item(s) as complete in the tracking.
  • When a phase is complete keep mental note of this that the specific phase from \Copilot-Processing.md is done and does not need to be repeated.
  • Repeat this pattern until all action items are complete

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.
