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 5.1 | $0.00013 | $0.00441 |
| Opus 5 | $0.00006 | $0.00220 |
| Sonnet 5 | $0.00003 | $0.00088 |
| Haiku 4.5 | $0.00001 | $0.00044 |
Grade A, and why
3-osp-historian 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 12d 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
/3-osp-historian — Sub-Domain Historian
Compresses the retrieved literature into a chronological narrative that mimics a senior researcher's mental model of the sub-domain.
Activation
Invoke the osp-historian-agent skill.
Prerequisites
phases.literature.status == "completed"and02_retrieved_literature.mdexists.
Steps
- Read
.brain/session.json,.brain/raw/01_structured_summary.md,.brain/raw/02_retrieved_literature.md. - Activate the
osp-historian-agentskill. - The skill builds a chronological narrative grouped by inflection points (eras), each characterized by its dominant approach and what triggered the transition out.
- The skill places the paper under review in the narrative — same era it claims, or a different one — and identifies its closest precedents.
- Write
.brain/raw/03_domain_narrative.md. - Write
.brain/raw/03_domain_narrative.md. - Update
session.json:phases.historian.status = "completed"phases.historian.notes = "<N> eras identified; paper placed in era <N>"resume_from = "baseline_scout"

Re-run behavior
Re-running overwrites 03_domain_narrative.md. Warn before doing so.
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.

3-osp-historian is a command published in the GitHub repository amirkiarafiei/open-scholar-peer (28 stars, last pushed yesterday), licensed MIT. It adds 13 tokens to every session and 441 once invoked, about $0.0001 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.
