What is OctopPet AGENTS.md?

A navigation and collaboration guide for Octop Pet, a desktop companion application. It tells coding agents to state assumptions, prefer small changes, edit only relevant code, and verify their work.

Use it when planning, implementing, reviewing, or testing changes in Octop Pet. It helps with choosing simple solutions, making focused edits, cleaning up code introduced by the change, and reporting whether the full checks pass.

It reduces unnecessary refactoring and makes agent changes easier to review. It also sets a clear expectation that completed work should include evidence from the project's verification command.

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.

Model	Per session	Once invoked
Fable 5.1	$0.03643	$0.03643
Opus 5	$0.01821	$0.01821
Sonnet 5	$0.00729	$0.00729
Haiku 4.5	$0.00364	$0.00364

Security

Grade A, and why

OctopPet 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 9d 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.

AGENTS.md

Navigation guide for AI coding agents working in octop-pet.

1. Collaboration principles

Favor caution over speed; trivial tasks may relax these rules.

Think before writing

State assumptions up front; ask when unsure — do not guess.
When multiple interpretations exist, list them and let the user choose.
Suggest simpler approaches when they exist; stop when blocked and name what is unclear.

Simplicity first

Write the minimum code that solves the problem; no unrequested features or abstractions.
Do not add defensive error handling for scenarios that cannot realistically happen.
Trim the diff when it grows unnecessarily large.

Surgical edits

Touch only lines directly related to the task; do not opportunistically clean up nearby code.
Do not refactor working code or unify style just because it differs from yours.
Remove orphan imports, variables, and functions you introduced.

Verifiable outcomes

Turn tasks into verifiable goals (what to test, which command proves success).
Before saying "done", provide verification evidence; the default ship bar is make all green.

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.
