ontology-term-resolution

ontology-term-resolution is a skill for Claude Code from K-Dense-AI/scientific-agent-skills. It costs 201 tokens per session (2,133 once invoked), scanned A, original, MIT.

A tool for matching free-text scientific labels, such as a tissue or disease name, to official ontology identifiers. It also checks whether an existing identifier is valid and has the claimed meaning.

In plain words
What is it for?
Use it to resolve labels to ontology IDs or validate IDs in individual values and files through the EBI Ontology Lookup Service.
Why use it?
Scientific identifiers can look correct while silently referring to the wrong term. Verification reduces metadata errors in datasets, submissions, and published research.

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.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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

ontology-term-resolution 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 9d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/ols_client.py, scripts/resolve_terms.py, scripts/validate_terms.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.

Ontology Term Resolution

When to use

Any time an ontology identifier is about to be written down or trusted: annotating a metadata column, filling a submission template, auditing a table someone else produced, or checking whether an ID in an old file is still current.

The rule

Never write an ontology ID from memory, and never accept one without checking it.

Ontology IDs are memorable in form and arbitrary in detail. A plausible-looking UBERON:0002108 is a real term (small intestine) that is not the liver, and nothing downstream will catch the substitution — the ID is well-formed, the ontology is right, and the metadata is silently wrong. Reviewers cannot spot it either, which is why these errors persist into published datasets.

Every ID this skill emits comes from a live OLS lookup. Every ID it is handed gets verified.

Two directions

Direction Script Question answered
text → ID scripts/resolve_terms.py What is the term for "left ventricle"?
ID → verdict scripts/validate_terms.py Is EFO:0001067 real, current, and labelled what this file claims?

Both take single values or files, emit TSV or JSON, and need no packages beyond the standard library.

Resolve text to terms

cd skills/ontology-term-resolution/scripts

# one string, constrained to the ontology that should define it
python3 resolve_terms.py "liver" --ontology uberon
query   rank  curie           label  ontology  match_type   strategy  defining_ontology
liver   1     UBERON:0002107  liver  uberon    exact_label  exact     true
# a column of tissue names; anything not an exact hit is reported, not guessed
python3 resolve_terms.py --input tissues.txt --ontology uberon \
    --exact-only --format tsv -o resolved.tsv

# accept fuzzy fallbacks, then review the partial hits by hand
python3 resolve_terms.py "left ventrical of heart" --ontology uberon --top 3

The search escalates exact (label and synonym) → tokenfulltext and stops at the first strategy that returns anything, reporting which one fired. --exact-only disables the ladder. --branch UBERON:0000465 restricts candidates to descendants of a term.

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.
