molclaw-sequence-valid-check

molclaw-sequence-valid-check is a skill for Claude Code, Codex from InternScience/MolClaw. It costs 17 tokens per session (297 once invoked), scanned A, original, MIT.

A check for whether supplied protein sequences use a valid format and amino-acid content.

In plain words
What is it for?
Use it to submit one or more protein sequence strings and receive a validity result for each. Local files must be uploaded separately first.
Why use it?
It can identify invalid sequences before they are used in later protein analysis.

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

molclaw-sequence-valid-check 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 3d 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.

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.

What it actually says

Protein Sequence Valid Check

Note:

  • Local files are not directly accessible by the server. Please upload them to the server using molclaw-file-transfer before execution.
  • For PDB file inputs, it is recommended to preprocess them using molclaw-pdbfixer before execution.
  • Please refer to skill molclaw-scp-server to complete tool invocation.

The description of tool is_valid_protein_sequence.

Check if the input protein sequence string is valid.
Args:
    sequences (List[str]): List of input protein sequences
Return:
    status (str): success/partial_success/error
    msg (str): message
    valid_res (List[dict]): List of dict, each containing the keys 'sequence' and 'is_valid'.
        --sequence (str): A protein sequence of the input sequences list 
        --is_valid (bool): Is the protein sequence valid or not

How to use tool is_valid_protein_sequence :


response = await client.session.call_tool(
    "is_valid_protein_sequence",
    arguments={
        "sequences": sequence_list
    }
)
result = client.parse_result(response)
valid_res = result["valid_res"]

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.

molclaw-sequence-valid-check is a skill published in the GitHub repository InternScience/MolClaw (33 stars, last pushed 27d ago), licensed MIT. It adds 17 tokens to every session and 297 once invoked, about $0.0001 per session on Opus 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.
