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 | $0.00072 | $0.00452 |
| Opus 5 | $0.00036 | $0.00226 |
| Sonnet 5 | $0.00014 | $0.00090 |
| Haiku 4.5 | $0.00007 | $0.00045 |
Grade A, and why
benchmark 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
benchmark
Put numbers on the comparison. MemMesh ships a real benchmark harness that runs the public LOCOMO dataset end-to-end against competing systems.
What it compares
Systems: thinkfleet (MemMesh) vs full_context vs naive_rag, and — with keys
— Mem0 / Zep. Metrics: answer accuracy (rubric-scored), tokens consumed, latency,
and cost per conversation.
Run it
The harness lives in the engine repo at crates/eval/competitive/:
cd crates/eval/competitive
python bench.py --systems thinkfleet,mem0,full_context --dataset locomo
# results land in results/
(Set the competitors' API keys via env for a head-to-head; without them you still get MemMesh vs full-context vs naive-RAG.)
Report honestly
MemMesh's positioning is calibration over raw accuracy — "80% means 80%" and honest abstention beat a slightly higher accuracy with overconfident wrong answers. So report the full picture:
- accuracy and calibration error,
- tokens / latency / cost (MemMesh's retrieval is far cheaper than full-context),
- where MemMesh abstained vs. where a competitor answered confidently and wrong.
Don't cherry-pick a single accuracy number. If a competitor wins on one axis, say so, and show where MemMesh's calibration/cost advantage pays off.
Cost gating
Prove the win on the cheap tiers (LOCOMO, BEAM-100K) before spending on BEAM-1M/10M — a single 10M-token conversation is expensive. Escalate tiers only once the cheaper tier shows a clear, defensible lead.
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.

benchmark is a skill published in the GitHub repository ThinkfleetAI/memmesh (440 stars, last pushed 7d ago), licensed Apache-2.0. It adds 72 tokens to every session and 452 once invoked, about $0.0004 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.
