tamarind

tamarind is a skill for Claude Code, Codex from K-Dense-AI/scientific-agent-skills. It costs 172 tokens per session (6,417 once invoked), scanned A, original, MIT.

A cloud service that runs computational biology tools on managed GPUs. You send it biological sequences or structures and receive predicted structures, designed proteins or binders, docking results, and other scientific outputs through a common job interface.

In plain words
What is it for?
Use it for protein and antibody design, structure prediction, molecular docking, binding-affinity estimation, multiple-sequence alignment generation, and molecular dynamics.
Why use it?
It removes the need to install and operate specialized biology software or provide your own GPU hardware. A single interface can cover many structure-prediction, design, docking, and simulation tools.

About the project

Scientific Agent Skills is a collection of reusable procedures that give AI agents capabilities for scientific research across areas such as biology, chemistry, medicine, and drug discovery. It is used by researchers and by people building AI scientist workflows with compatible coding agents. The catalogue contains many of the project's skills and supporting instructions.

    Skill allows unbounded resource consumption (API calls, storage, compute). Without rate limits or quotas, a compromised or misbehaving agent can cause denial-of-service or cost overruns.
    Fix: Set explicit rate limits, timeouts, and resource quotas for API calls, file operations, and compute. Implement circuit breakers for runaway loops.

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

tamarind scanned grade A with 1 finding 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.

Tamarind Bio

Tamarind Bio is a cloud platform that runs computational biology tools — structure prediction, protein and antibody design, docking, binding-affinity, MSA generation, and molecular dynamics — on managed GPUs. Users submit sequences or structures and get back predicted structures, designs, and biophysical scores, without provisioning their own hardware. It exposes hundreds of tools (AlphaFold, Boltz-2, Chai-1, RFdiffusion, ProteinMPNN, BoltzGen, ESMFold2, DiffDock, Autodock Vina, and many more) through one uniform job API.

Official docs: app.tamarind.bio/api-docs · platform UI at app.tamarind.bio

Canonical sources — fetch these, don't rely on a stale copy

Tamarind publishes live, machine-readable sources. Prefer fetching them at runtime over trusting any hardcoded list — tool names, schemas, and endpoints change frequently:

  • https://app.tamarind.bio/llms.txt — LLM index: links to the spec, API docs, and MCP guide.
  • https://app.tamarind.bio/openapi.yaml — OpenAPI 3.0 spec for the 8 core job endpoints (submit-job/-batch, jobs, result, upload, files, delete-job/-file; auth ApiKeyAuth). Fetch it for those exact shapes. Discovery/management endpoints (/tools, /usage-statistics, pipelines, …) aren't in it — use the MCP/REST discovery tools for those.
  • https://docs.tamarind.bio/llms.txt — documentation index; every page has a .md form (e.g. docs.tamarind.bio/tamarind/batch.md, /tamarind/api.md, /tamarind/pipelines.md).
  • Live tool discoveryGET /tools (REST) or MCP getAvailableTools + getJobSchema(jobType) are the source of truth for what tools exist and their parameters.

This skill teaches the surface + the non-obvious behaviors those sources don't spell out (see the reference files). When in doubt about a shape, fetch openapi.yaml.

When to use this skill

Use Tamarind when the user wants to:

  • Predict structure of a protein, complex, or protein-ligand system (AlphaFold, Boltz-2, Chai-1, ESMFold2, Chai/Boltz cofolding)
  • Design proteins or binders (RFdiffusion, BoltzGen, BindCraft, ProteinMPNN/LigandMPNN inverse folding)
  • Design or characterize antibodies/nanobodies (sequence generation, humanization, developability, immunogenicity)
  • Dock small molecules to a protein (DiffDock, Autodock Vina) or predict binding affinity
  • Generate MSAs for downstream folding
  • Run molecular dynamics or other biophysical workflows on managed GPUs
  • Batch-screen many sequences or designs through the same tool
  • Chain tools into pipelines (e.g. design → fold → score) using the output of one job as the input of the next

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.

tamarind is a skill published in the GitHub repository K-Dense-AI/scientific-agent-skills (44,220 stars, last pushed 4d ago), licensed MIT. It adds 172 tokens to every session and 6,417 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
