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 | $0.00130 | $0.01668 |
| Opus 5 | $0.00065 | $0.00834 |
| Sonnet 5 | $0.00026 | $0.00334 |
| Haiku 4.5 | $0.00013 | $0.00167 |
Grade A, and why
longmemeval-run scanned grade A with 1 finding 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 3d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
`curl` / `python` invocation in chat. How it starts
The opening of the file, as written. The whole thing — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
LongMemEval One-Shot Run
When to invoke
- User just did
git cloneand asks "how do I run LongMemEval" - User says "run the benchmark" / "open-box test" / "first run"
- Previous run failed and the user wants to retry from scratch
- A new chat / embed / judge provider was added — verify each endpoint then re-run the full benchmark
- After
git pullbrings new code — verify and re-run
Do NOT invoke if the user is asking to iterate on the score (that's
longmemeval-iterate) or to run another benchmark (LoCoMo, etc.).
Recommended stack (defaults)
These are the models the script pings at steps 6-8 and then uses in the
full N=500 run. Defaults live in scripts/parallel_longmemeval.sh
(source of truth) and are mirrored in scripts/run.sh for the ping
checks.
| Role | Default | Why |
|---|---|---|
| reader | openai:gpt-5 (reasoning_effort=high auto) |
the qa_answer prompt assumes a reasoning model — strongest available reader |
| writer | openai:gpt-5 (reasoning_effort honored from env) |
strongest extractor — preserves attributes the user named verbatim |
| judge | openai:gpt-4o |
canonical LongMemEval judge; do not substitute without re-calibrating against published numbers |
| rerank | openai:gpt-5 (batched, pool=100) |
one batched call per question; handles "27th item" / ordinal references |
| embed | openai:text-embedding-3-large (1536 dim via API dimensions param) |
strongest embedding; cognifold/embeddings/providers.py passes dimensions=1536 so the graph schema stays compatible |
Override any role by exporting READER_MODEL / WRITER_MODEL /
JUDGE_MODEL / RERANK_MODEL / EMBED_MODEL before invoking the
script.
Stratified sampling: 133 per question type (one type, temporal- reasoning, has 133 questions — the cap means "take all" for every
type, so the full 500 set is processed). Override with the second
positional arg to scripts/parallel_longmemeval.sh if needed.
W1 (EXTRACT_TYPED_ATTRIBUTES=1) is enabled by default in run.sh.
W2 (RESOLVE_EVENT_DATES=1) is off by default.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

longmemeval-run is a skill published in the GitHub repository OpenUploading/CogniFold (59 stars, last pushed 9d ago), licensed Apache-2.0. It adds 130 tokens to every session and 1,668 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
