Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00675 | $0.00675 |
| Opus 5 | $0.00338 | $0.00338 |
| Sonnet 5 | $0.00135 | $0.00135 |
| Haiku 4.5 | $0.00068 | $0.00068 |
Grade A, and why
agent-loop-learning 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 2d 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.

GitHub Copilot Instructions — Agent Loop Learning
This repo is a reference library for auditing, reviewing, and improving LLM-based agent systems. The best-practice docs in best-practices/ are framework-agnostic and apply to any agent on any model.
When to use the best-practice docs
Always read the relevant doc before answering questions about:
- Agent architecture or design patterns
- Prompt structure, system prompts, or worker prompts
- Memory, context windows, or RAG pipelines
- Tool design or function calling
- Testing or verification strategies
- Security, permissions, or prompt injection
- Performance, latency, or startup behavior

Review workflow
When asked to review or audit an agent design:
- Explore the current repo first — do not ask the user for anything. Search for agent-related files (
*agent*,*tool*,*prompt*,*chain*,*workflow*), framework imports (langchain,openai,anthropic,autogen,crewai), system prompt definitions, and anyCLAUDE.md,AGENTS.md, or README describing the architecture. Read the relevant files. Only ask if no agent code is found. - Read all 9 docs.
- Score each dimension: ✅ Solid / ⚠️ Partial / ❌ Gap.
- Return scorecard, top 3 prioritized improvements (with benchmark citations), and callouts for what's strong.
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.

agent-loop-learning copilot-instructions.md is an instructions file published in the GitHub repository sarkarsaurabh27/agent-loop-learning (3 stars, last pushed 3mo ago), licensed MIT. It adds 675 tokens to every session, about $0.0034 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.
