Claude Scholar is a semi-automated research assistant for academic research and software development, supporting literature review, coding, experiments, reporting, writing, and project knowledge management. Computer science and AI researchers use it across the research workflow with several coding-agent platforms; the catalogue contains its skills, commands, agents, hooks, plugin, and instruction.
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.

What 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 5.1 | $0.00064 | $0.00528 |
| Opus 5 | $0.00032 | $0.00264 |
| Sonnet 5 | $0.00013 | $0.00106 |
| Haiku 4.5 | $0.00006 | $0.00053 |
Grade A, and why
obsidian-project-kb-core 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 8d 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
Obsidian Project KB Core
This is the main workflow authority for project-scoped Obsidian knowledge maintenance.
Default project root:
Research/{project-slug}/
Default structure:
00-Hub.md
01-Plan.md
02-Index.md
Sources/
Knowledge/
Experiments/
Results/
Reports/
Writing/
Daily/
Maps/
Archive/
_system/
Core rules
- Keep all durable project knowledge inside the current
Research/{project-slug}/. - Keep repo-local
.claude/project-memory/*only as the runtime binding layer. _system/registry.mdis the only visible project registry.02-Index.mdis a human navigation note, not a registry mirror.Maps/is a derived-artifact area; do not generate non-essential canvases by default.Results/Reports/is the default subdirectory for round and batch experiment reports.
Responsibilities
- detect and bind the current repo to a project root
- bootstrap the project skeleton
- route notes into
Sources / Knowledge / Experiments / Results / Results/Reports / Writing / Daily / Maps / Archive - update
00-Hub.md,01-Plan.md,02-Index.md - update
_system/registry.md,_system/schema.md,_system/lint-report.md - handle note lifecycle actions: create, update, rename, archive, purge, promote, and link repair
- run deterministic health checks through helper scripts
Deterministic helpers
Use the scripts under scripts/ for:
- scaffold
- registry consistency
- link checks
- index checks
- canvas checks
- lint aggregation
Use agents for:
- note routing
- daily promotion decisions
- source vs knowledge judgment
- stable-result judgment
- semantic Hub and Index updates

What ships with it
15 files 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.

obsidian-project-kb-core is a skill published in the GitHub repository Galaxy-Dawn/claude-scholar (5,431 stars, last pushed 15d ago), licensed MIT. It adds 64 tokens to every session and 528 once invoked, about $0.0003 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 2026-09-03.
