Project instructions for configuring an AI coding agent in a modular development project. They focus on short instructions, clear file references, controlled scope, small changes, and verification.

In plain words

Use them when writing or reviewing agent instructions, adding configuration rules, guiding file inspection, and setting expectations for patches and verification.
Why use it?
They reduce unclear agent behavior, invented configuration settings, oversized context, and unreported skipped checks.

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

pudo-code-system ai-agent-config.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

AI Agent Config Instructions

  • Keep agent instructions short enough to load as context.
  • Put detailed procedures in skills, prompts, or quality docs instead of duplicating them.
  • Preserve compatibility files when adding newer config formats.
  • Name exact files and paths agents should read.
  • Do not invent tool-specific settings; verify config keys before adding them.
  • Include rules for scope control, file inspection, small patches, verification, and skipped-check reporting.
  • Avoid model-specific claims unless the task explicitly requires them.
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.
