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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00397 |
| Opus 5 | $0.00000 | $0.00198 |
| Sonnet 5 | $0.00000 | $0.00079 |
| Haiku 4.5 | $0.00000 | $0.00040 |
Grade A, and why
checkpoint 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
Checkpoint Command
Create or verify a checkpoint in your workflow.
Usage
/checkpoint [create|verify|list] [name]
Create Checkpoint
When creating a checkpoint:
- Run
/verify quickto ensure current state is clean - Create a git stash or commit with checkpoint name
- Log checkpoint to
.claude/checkpoints.log:
echo "$(date +%Y-%m-%d-%H:%M) | $CHECKPOINT_NAME | $(git rev-parse --short HEAD)" >> .claude/checkpoints.log
- Report checkpoint created
Verify Checkpoint
When verifying against a checkpoint:
-
Read checkpoint from log
-
Compare current state to checkpoint:
- Files added since checkpoint
- Files modified since checkpoint
- Test pass rate now vs then
- Coverage now vs then
-
Report:
CHECKPOINT COMPARISON: $NAME
============================
Files changed: X
Tests: +Y passed / -Z failed
Coverage: +X% / -Y%
Build: [PASS/FAIL]
List Checkpoints
Show all checkpoints with:
- Name
- Timestamp
- Git SHA
- Status (current, behind, ahead)
Workflow
Typical checkpoint flow:
[Start] --> /checkpoint create "feature-start"
|
[Implement] --> /checkpoint create "core-done"
|
[Test] --> /checkpoint verify "core-done"
|
[Refactor] --> /checkpoint create "refactor-done"
|
[PR] --> /checkpoint verify "feature-start"
Arguments
$ARGUMENTS:
create <name>- Create named checkpointverify <name>- Verify against named checkpointlist- Show all checkpointsclear- Remove old checkpoints (keeps last 5)
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.

checkpoint is a command published in the GitHub repository Galaxy-Dawn/claude-scholar (5,349 stars, last pushed 11d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 397 tokens. 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.
