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 | $0.00268 | $0.01564 |
| Opus 5.5 | $0.00107 | $0.00626 |
| Sonnet 5.5 | $0.00054 | $0.00313 |
| Haiku 4.5 | $0.00027 | $0.00156 |
Grade A, and why
remember 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 2mo 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.
This is a copy
86% identical to remember — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.
remember — write to the shared eidetic memory
remember drives eidetic remember, the write half of the memory surface
(the read half is the sibling /recall skill). Records you store here are
recallable later by any agent on this machine — Claude or the colleague
backend — because the default store is one shared ~/.eidetic/memory path.
How to run
# One record (JSON object as the argument):
bash .claude/skills/remember/scripts/remember.sh \
'{"id":"d1","text":"Orin Nano draws 7-15W","type":"docs","metadata":{"source":"docs","permalink":"https://..."}}' --json
# Batch (NDJSON on stdin, one record per line) — for bulk re-index:
cat records.ndjson | bash .claude/skills/remember/scripts/remember.sh --json
# Record that supersedes an older one (same scope required for sweep to shadow):
bash .claude/skills/remember/scripts/remember.sh \
'{"id":"r2","text":"Updated Orin Nano draw: 10-20W","type":"note","supersedes":"r1","links":["r3"]}' --json
The wrapper resolves the CLI portably (installed eidetic on PATH, else
uv run eidetic from the checkout) and forwards every flag verbatim.
Record shape
| Field | Required? | Notes |
|---|---|---|
id |
yes | stable identity; the upsert key |
text |
yes | the chunk being remembered |
type |
yes | e.g. note, docs, discord, a research object type |
hash |
optional | content hash for dedup; derived from text when omitted |
metadata |
recommended | provenance + facets; round-trips verbatim on recall |
created |
auto-stamped | ISO-8601 UTC date; stamped at ingest if absent; drives freshness signal age-decay |
supersedes |
optional | id of an earlier same-scope record this one replaces; sweep auto-shadows the target |
links |
optional | list of related-memory ids; persisted for future corroboration scoring |
score and signal are recall-only and are ignored on ingest. Mind the
scope: the default personal scope is private (--scope arxivist --visibility private), so personal/role-gated notes stay isolated to this
agent's recall and are safe to store. Only when you deliberately write to a
public scope (--visibility public) does the record enter the shared pool
visible to every scope — keep public-scope records to public data only.
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.
- 2mo ago First seen · 119 lines · 268 tokens per session scan A 485779862710
remember is a skill published in the GitHub repository agentculture/arxivist (2 stars, last pushed 3mo ago), licensed MIT. It adds 268 tokens to every session and 1,564 once invoked, about $0.0011 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 86% identical to remember, differing in 6 lines, and is treated as a copy.
