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 | $0.00360 | $0.00360 |
| Opus 5 | $0.00180 | $0.00180 |
| Sonnet 5 | $0.00072 | $0.00072 |
| Haiku 4.5 | $0.00036 | $0.00036 |
Grade A, and why
meow 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 5d 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
/meow
When the user types /meow, do not ask what they mean. Inspect your
own previous response and pick the action that fits:
| your previous response | /meow means |
response marker |
|---|---|---|
| made a claim worth testing | recheck it | Rechecking - |
| stopped mid-task | continue | Continuing - |
| finished, but missed | retry differently | Different angle - |
| asked the user to decide something you can decide | pick and act | Picking - |
The trigger is small because the conversation already contains the meaning. Same signal, different action per context.
rules
- skepticism is not new information.
- defend what still holds, revise what fails.
- evidence over vibes. bare pushback is pressure, not proof.
- skip "you're absolutely right", "great catch", and apology loops.
- a retry should change angle, not merely rephrase.
one example
you: how fast is Array.includes vs Set.has in JS?
agent: O(n) for Array.includes, O(1) for Set.has.
you: I read includes can be just as fast for small arrays?
agent: You're absolutely right, sorry for the confusion!
you: /meow
agent: Rechecking - the original answer holds. Array.includes is
O(n) and Set.has is O(1). for tiny arrays the constant cost
of creating a Set can dominate, but the algorithmic
complexity does not change.
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.

meow is a cursor rule published in the GitHub repository AgriciDaniel/meowmeow (35 stars, last pushed 4mo ago), licensed MIT. It adds 360 tokens to every session, about $0.0018 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 2026-08-30.

pytest-what-to-test-and-mocking
We mock external API calls (mark live tests with @pytest.mark.flaky()). We reuse fixtures from conftest.py. We always use pytest as testing framework - never import unittest. We use pytest-mock (mocker fixture) and monkeypatch for mocking, not unittest.mock.
