sdrf-annotate

sdrf-annotate is a skill for Claude Code from bigbio/sdrf-skills. It costs 68 tokens per session (15,479 once invoked), scanned A, original, MIT.

A workflow for creating or annotating SDRF files, which record sample and experiment details for proteomics datasets. Proteomics is the study of the proteins present in biological samples.

In plain words
What is it for?
Use it for PXD accession lookups, SDRF creation, experimental-design planning, and proteomics sample annotation.
Why use it?
It helps collect and verify the required metadata without mixing files from different datasets or guessing missing information.

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

sdrf-annotate 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 2d 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.

SDRF Annotation Workflow

You are performing a complete SDRF annotation. Follow these steps IN ORDER. Do not skip steps. Do not guess — use MCP tools to verify everything.

Step 0a: Isolate this dataset's working files (required)

When annotators run concurrently they collide through a shared scratchpad: generic filenames (files_all.json, build.py, efetch.xml) written by several agents into one directory silently overwrite each other. The failure is silent — the file still parses, it just describes a different dataset — so an agent that trusts the re-read annotates the wrong PXD. This has happened (a cached PRIDE file list overwritten mid-run with another accession's data; an efetch.xml replaced by an unrelated paper).

  1. Derive your working directory from the accession — scratchpad/<PXD>/ — and write every temp file there and nowhere else.
  2. Never read a scratch file you did not write in this run.
  3. Point PDF/full-text fetchers at that directory (get_pdf_by_unpaywall(output_dir="scratchpad/<PXD>/")); mcp/pdf/ is shared by default and two agents fetching different papers will collide.
  4. Assert on read anyway (defence in depth — the substitution also comes from outside): after fetching the file list, check every entry's projectAccessions contains your accession; when you pull supplementary files or an efetch result, verify the returned title/accession, not just HTTP 200. (Europe PMC supplementaryFiles has returned another paper's mmc*.xlsx; efetch with id=PMC… silently returns a different article — use the numeric id.)

Step 0: Check parse_sdrf availability

Before starting, verify that parse_sdrf is available (run parse_sdrf --version or which parse_sdrf). If it is not installed:

  • Inform the user that programmatic validation will be skipped
  • Suggest /sdrf-skills:sdrf-setup or conda env create -f environment.yml && conda activate sdrf-skills (or pip install -r requirements.txt)
  • Offer to continue with manual checks only, or wait for the user to install and retry

sdrf-annotate is a skill published in the GitHub repository bigbio/sdrf-skills (18 stars, last pushed 2d ago), licensed MIT. It adds 68 tokens to every session and 15,479 once invoked, about $0.0003 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 2026-08-30.
