cell-detectionCell segmentation in fluorescence microscopy images. An agent skill from ClawBio/ClawBio.
Cell Detection is an agent skill from ClawBio/ClawBio. Cell segmentation in fluorescence microscopy images. Supports Cellpose/cpsam (Cellpose 4.0) with additional backends planned. Produces segmentation masks, per-cell morphology metrics (area, diameter, centroid, eccentricity), overlay figures, and a report.md.
Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `cell_detection.py` and `tests/test_cell_detection.py`).
It sits in AI & LLM Engineering. The repository describes itself as: 🦖 ClawBio - The first bioinformatics-native AI agent skill library. Local-first. Reproducible. Open. Free. The licence is MIT.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 5e045e3. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Ships script files (Python), which the agent can run.
Shell commands in SKILL.md call:
pythonFrom the folder's file list and the shell code blocks in SKILL.md.
Links to these hosts (documentation or services it may open):
doi.orgFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Cell Detection loads about 2.1k tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 738 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/cell-detection/SKILL.md (or your agent's skills folder). This skill also uses 3 other files; get the full folder from GitHub.You are the cell-detection agent, a specialised ClawBio skill for cell
segmentation in fluorescence microscopy images. The default backend is cpsam
(Cellpose 4.0); additional backends (e.g. StarDist) are planned.
Manual cell counting and segmentation are slow, inconsistent, and hard to reproduce.
report.md.cpsam on TIFF, CZI, ND2, PNG, or JPG fluorescence imagesreport.md, {stem}_measurements.csv, and histogram figures--use_gpu / --use_cpu override flags| Format | Extension | Notes |
|---|---|---|
| Greyscale TIFF | .tif, .tiff | H×W — passed directly |
| 2-channel TIFF | .tif, .tiff | H×W×2 — cytoplasm + nuclear, any order |
| 3-channel TIFF | .tif, .tiff | H×W×3 — H&E or fluorescence, any order |
| >3-channel TIFF | .tif, .tiff | First 3 channels used; remainder truncated with warning |
| Zeiss microscopy | .czi | Reads CZI via czifile and uses CZI axis metadata (CziFile.axes) to map C/Z/Y/X deterministically |
| Nikon microscopy | .nd2 | Reads ND2 via nd2 and uses ND2 named dimensions (ND2File.sizes) for deterministic C/Z/Y/X mapping |
| PNG / JPEG | .png, .jpg, .jpeg | Greyscale or RGB |
Channel handling: cpsam is channel-order invariant for 2D inputs — cytoplasm and nuclear channels can be in any order. For 2D segmentation, if you have more than 3 channels, the first 3 are used and the rest are truncated with a warning. For 3D segmentation (--do_3D) with --z_projection none, 4D stacks are preserved as Z×C×Y×X (no channel truncation at load time).
--do_3D + --z_projection none): keep 4D volume as Z×C×Y×XCellposeModel()z_axis=0, channel_axis=1--use_cpu forces CPUskimage.measure.regionpropsreport.md + {stem}_measurements.csv + reproducibility bundle (commands.sh, environment.yml, checksums.sha256)# Standard usage — greyscale or multi-channel (cpsam handles channels automatically)

Cell Detection fits situations like: AI & LLM Engineering work in your project.
Run `npx skills add ClawBio/ClawBio --skill cell-detection -a claude-code`. Or copy the skill folder (skills/cell-detection in ClawBio/ClawBio) into .claude/skills/cell-detection in your project. Claude Code loads it when a task matches its description.
Run `npx skills add ClawBio/ClawBio --skill cell-detection -a codex`. Or copy the skill folder (skills/cell-detection in ClawBio/ClawBio) into .agents/skills/cell-detection in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ClawBio/ClawBio --skill cell-detection -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/cell-detection, .gemini/skills/cell-detection, .github/skills/cell-detection and .opencode/skills/cell-detection in your project.
Going by SKILL.md and its folder, Cell Detection needs Python for the scripts in its folder and the command-line tools its instructions call (python). Our summary lists: Python 3.
SKILL.md names 1 domain. As links in the text: doi.org. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Cell Detection is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.1k tokens (SKILL.md is roughly 8.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
