asl-skill
Use this skill whenever the user wants to process Arterial Spin Labeling (ASL) perfusion MRI data including CBF (cerebral blood flow) quantification, ASL preprocessing (motion correction, partial volume correction, M0 normalization), or ASL-based brain perfusion analysis. Triggers include: 'ASL', 'ASL processing', 'CBF', 'cerebral blood flow', 'perfusion MRI', 'arterial spin labeling', 'pCASL', 'CASL', 'PASL', or any request involving ASL perfusion data.
npx skills add BioTender-max/awesome-bio-agent-skills --skill asl-skill --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.

# ASL Skill (Modality Layer) ## Overview `asl-skill` is the NeuroClaw **modality-layer** interface skill responsible for all Arterial Spin Labeling (ASL) perfusion MRI data processing tasks. It strictly follows the NeuroClaw hierarchical design principles: - This skill **only describes WHAT needs to be done** and **which tool skill to delegate to**. - It contains **no implementation code or concrete commands**. - All concrete execution is delegated to existing base/tool skills: `fsl-tool`, `nibabel-skill`, and `claw-shell`. - Companion scripts in `scripts/` provide reference implementations for CBF quantification. **Core workflow (never bypassed):** 1. Identify input ASL data and labeling strategy (pCASL, CASL, or PASL). 2. Ensure T1w structural data is available (via `smri-skill` if not yet processed). 3. Generate a **numbered execution plan** clearly stating WHAT needs to be done and which tool skill will handle each step. 4. Present the full plan, estimated runtime, resource requirements, and risks to the user and wait for explicit confirmation ("YES" / "execute" / "proceed"). 5. On confirmation, delegate every step to the appropriate skill via `claw-shell`. 6. After execution,

What does the asl-skill skill do?
Use this skill whenever the user wants to process Arterial Spin Labeling (ASL) perfusion MRI data including CBF (cerebral blood flow) quantification, ASL preprocessing (motion correction, partial volume correction, M0 normalization), or ASL-based brain perfusion analysis. Triggers include: 'ASL', 'ASL processing', 'CBF', 'cerebral blood flow', 'perfusion MRI', 'arterial spin labeling', 'pCASL', 'CASL', 'PASL', or any request involving ASL perfusion data.
How do I install it?
Run `npx skills add BioTender-max/awesome-bio-agent-skills --skill asl-skill --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From BioTender-max/awesome-bio-agent-skills, a repository with 135 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
