agentforge copilot-instructions.md

Coding instructions for AgentForge, an AI-assisted codebase. They describe coding style, security checks, architecture, and testing expectations.

In plain words
What is it for?
Use them when adding features or fixing bugs to guide validation, module design, secure coding, and automated test coverage.
Why use it?
They reduce risks such as leaked secrets, unchecked input, tangled modules, and missing tests.

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

agentforge 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 yesterday.

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.

Coding Guidelines

  • Write minimal, concise, and robust code. Avoid over-engineering (YAGNI).
  • Follow language idioms and leverage the standard library before third-party abstractions.
  • Never compromise on security, input validation, error handling, or accessibility.
  • Maintain existing style, patterns, and architectural conventions across edits.

Security & Architecture

  • Never hardcode API keys, secrets, credentials, or private tokens in source code or rules.
  • Sanitize and validate all external inputs, request payloads, and query parameters.
  • Keep modules focused, decoupled, and single-responsibility.
  • Colocate tests, types, and documentation with the corresponding modules.

Testing Instructions

  • Ensure all new features, edge cases, and bug fixes have automated test coverage.
  • Keep tests deterministic, isolated, and fast.
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.

agentforge copilot-instructions.md is an instructions file published in the GitHub repository mrzroot/agentforge (2 stars, last pushed 15d ago), licensed MIT. It adds 210 tokens to every session, about $0.0011 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
