onescience-primitives

onescience-primitives is a skill for Claude Code from onescience-ai/OneSkills. It costs 99 tokens per session (16,403 once invoked), scanned A, original, MIT.

A resource-search tool for finding reusable OneScience building blocks. It searches a catalogue for the most relevant scientific workflow components and returns their supporting details and usage contracts.

In plain words
What is it for?
Use it to find OneScience primitives related to a request, then resolve their implementation parts, contracts, locations, and companion resources. It does not create an implementation plan, edit code, or run scripts.
Why use it?
It reduces the need to search through resource files manually or choose components without checking their intended scope. It also enforces a controlled process for retrieving those resources.

Token cost

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.

Security

Grade A, and why

onescience-primitives 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 1mo ago.

The scan reads SKILL.md. This mod also ships 12 executable files (assets/bio/application/bio_cell_imaging_cytometry_app/script/bio_cell_imaging_tools/cytometry_table_qc.py, assets/bio/application/bio_cell_imaging_cytometry_app/script/bio_cell_imaging_tools/label_mask_measurements.py, assets/bio/application/bio_lab_quality_asm_app/script/bio_lab_quality_tools/convert_to_asm.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

OneScience Primitives Resource

Primitive Unification Scope

This skill is the unified OneSkills primitive registry. A primitive is any reusable scientific capability that can be recalled, bound into a plan, handed to an executor, or used as planning evidence. Primitives may be first-party OneScience resources or third-party tools, packages, databases, services, datasets, workflow patterns, output formats, validation contracts, and execution templates.

Task-Centric Knowledge Layer: TC 知识对象与传统资源原语同构同址——一律是 assets/<domain>/<category>/<primitive>/ 下的 metadata.json + knowledge.md 文档组，不新增 metadata 字段、不改字段名，因此 catalog_search 逻辑不变。对象类型由 type 区分：

  • Task（type: task，category tasks/）：科研能力单元（如 material-property-prediction），含目标、输入输出契约、方法路线、操作序列、验证契约、实体槽
  • Workflow（type: workflow，category workflow/）：以 Task 为节点的编排（如 material-screening-workflow）
  • Scenario（type: scenario，category scenario/）：需求绑定与验收口径（如 material-candidate-screening）
  • Resource（type: model | tool | dataset | ...，各资源 category）：被 Task 引用的资源，含带可运行脚本的资源卡
  • Method / Operation / Validation：不单独建卡，作为 Task 卡 knowledge.md 的章节 + tags 词表边存在

知识图的全部连接关系编码在 tags 里（命名空间前缀 edge: / slot: / atom:），字段契约见 references/tc/card_contract.md。

Third-party tools can be primitives. Record the source through provider / provenance metadata and expose only distilled content through resource_retrieval_result; do not require a permanent bridge skill unless the provider needs its own retrieval backend, credentials, lifecycle, or access policy.

Use onescience-primitive-distiller when a new external scientific agent skill or third-party capability needs to be converted into primitive assets. This skill remains retrieval-only: it returns existing primitive content through the resource contract and does not perform distillation, migration, file creation, or script promotion itself.

When an application or workflow primitive depends on a specific primitive such as bio.tools.scanpy, expose that relationship through primitive_dependencies in the consumer metadata and mention the primitive_id in the consumer spec or workflow notes.

Changes

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.

onescience-primitives is a skill published in the GitHub repository onescience-ai/OneSkills (23 stars, last pushed today), licensed MIT. It adds 99 tokens to every session and 16,403 once invoked, about $0.0004 per session on Opus 5.5. 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.
