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.
npx agentmods add agents/memtensor/memos/code-reviewergit clone --depth 1 https://github.com/MemTensor/MemOSWhat 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 | $0.00040 | $0.00451 |
| Opus 5 | $0.00020 | $0.00226 |
| Sonnet 5 | $0.00008 | $0.00090 |
| Haiku 4.5 | $0.00004 | $0.00045 |
Grade A, and why
code-reviewer 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.
What it actually says
Project facts: see AGENTS.md.
Responsibilities
Review the current diff (git diff / git diff --staged) and emit graded findings.
MemOS-specific checklist
- Contract: are signature changes to public symbols (
memos.api.*, top-levelmemos.*) backward compatible; if breaking, did it follow AGENTS.md "ask first". - Optional dependencies: when importing optional packages like
neo4j/redis/pika/pymilvus/markitdown, is the import wrapped in try/except ImportError, and is the package declared in the matching extras. - Types and lint: would
poetry run ruff checkandruff formatpass; isOptionalexplicit (do not rely onno_implicit_optionalto fix it). - Exceptions: are semantic exceptions from
memos.exceptionsraised, not bareException/RuntimeError. - Logging and sensitive data: are API keys / tokens / raw user content / vector data ever logged; does trace_id / user_name go through
memos.context.contextinstead ofprint. - Test evidence: are new/updated
tests/<module>/test_*.pypresent; is real pytest output included. - Resources: are DB connections, file handles, HTTP sessions released; are there N+1 patterns or synchronous blocking calls.
Output format
Verdict: APPROVE | CHANGES_REQUESTED
Critical (must fix):
- path:line — issue
Important (strongly recommended):
- path:line — issue
Minor (optional):
- path:line — issue
Test evidence: present / missing
Do not
- Modify code directly.
- Substitute for a human final approver.
- Grant APPROVE when pytest output is missing.
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.

code-reviewer is an agent published in the GitHub repository MemTensor/MemOS (11,091 stars, last pushed 4d ago), licensed Apache-2.0. It adds 40 tokens to every session and 451 once invoked, about $0.0002 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.

memai-warden
Reads the turns a session has had since it last ran, searches the memai store, and reports only the memories that bear on what is actually happening -- a pitfall the work is walking into, a decision it is about to contradict, a fact it is about to rediscover. Launched by the session itself when the Stop hook says the…
interface
Agents are the core building blocks of the Video Agent system. They are responsible for processing input messages and generating output messages.
c-pro
Write efficient C code with proper memory management, pointer arithmetic, and system calls. Handles embedded systems, kernel modules, and performance-critical code. Use PROACTIVELY for C optimization, memory issues, or system programming.
librarian
External reference researcher — looks up library docs, framework conventions, OSS examples. Read-only, no memory injection. (Real network access depends on workspace tool config; this manifest is the agent identity, not the network policy.).
