floop AGENTS.md

Contributor instructions for floop, a persistent-memory system for coding agents. It stores lessons from corrections and can load relevant working habits into later sessions.

In plain words
What is it for?
Use it to save corrected behaviors, review active or stored memories, mark memories as helpful or wrong, and remove duplicates.
Why use it?
It helps an agent remember corrections across sessions instead of repeating the same mistake.

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.

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

floop AGENTS.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.

Floop - Agent Instructions

For floop contributors. If you're a user, see docs/integrations/ for setup guides.

Floop Integration (REQUIRED)

You have persistent memory via floop. Learned behaviors are loaded via MCP and, where supported, auto-injected via hooks.

When corrected, IMMEDIATELY capture it:

mcp__floop__floop_learn(right="what to do instead")

# With optional context about what went wrong:
mcp__floop__floop_learn(right="what to do instead", wrong="what you did (optional)")

# With explicit tags (optional, for pack filtering):
mcp__floop__floop_learn(right="what to do instead", tags=["topic", "category"])

Do NOT wait for permission. Capture learnings proactively. The hooks will also auto-detect corrections, but explicit capture is more reliable.

For non-Claude agents, see docs/integrations/agent-prompt-template.md.

Available MCP tools:

  • floop_active - See currently active behaviors for this context
  • floop_learn - Capture a correction (USE PROACTIVELY)
  • floop_feedback - Signal whether a behavior was helpful (confirmed) or contradicted (overridden)
  • floop_list - List all stored behaviors
  • floop_deduplicate - Merge duplicate behaviors

Codex Runtime Cadence (No Lifecycle Hooks)

In Codex environments, treat these as required pseudo-hooks:

  1. Task start: Call floop_active with current file and task.
  2. Context change (file/task/mode shift): Re-call floop_active.
  3. Correction received: Immediately call floop_learn (no permission needed).
  4. Behavior outcome: Call floop_feedback with confirmed or overridden.

If MCP is unavailable, use CLI fallback immediately:

floop active --file <path> --task <task> --json
floop learn --right "what to do instead" --wrong "what happened" --file <path>
floop list --json

Project Overview

floop is a CLI tool that enables AI agents to learn from corrections and maintain consistent behavior across sessions.

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.
