bar_gene_summary

Retrieve a merged summary for an Arabidopsis locus including TAIR curator summary, Araport11 description, NCBI ID, and cross-database aliases.

Instructions

Fetch the BAR (Bio-Analytic Resource, U Toronto) merged ThaleMine + GAIA-aliases summary for an Arabidopsis locus. Returns the TAIR curator summary + Araport11 computational description from /thalemine/gene_information/ together with the NCBI Gene ID and cross-DB aliases (RefSeq, UniProt, TIGR locus-model IDs) from /gaia/aliases/. Arabidopsis only — ThaleMine carries taxon 3702 plus yeast/human for ortholog cross-reference. BAR is keyless and a Global Core Biodata Resource (2023); replaces the v0.9 subscription-gated tair_locus_info stub for the curator-summary use case.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
locusYesArabidopsis AGI locus, e.g. AT1G01010

Output Schema

TableJSON Schema
NameRequiredDescriptionDefault
locusYes
agiNoAGI primary identifier echoed by ThaleMine, e.g. "AT1G01010"
symbolNoGene symbol, e.g. "NAC001"
full_nameNoGene name from ThaleMine
tair_locus_idNoTAIR locus ID from Gene.secondaryIdentifier, e.g. "locus:2200935"
synonymsNoTAIR aliases (CSV from Gene.tairAliases, split on commas + stripped)
computational_descriptionNoGene.tairComputationalDescription — Araport11-sourced computed description
curator_summaryNoGene.tairCuratorSummary — the TAIR-curated functional summary prose
brief_descriptionNoGene.briefDescription — short blurb (often same as full_name)
tair_short_descriptionNoGene.tairShortDescription — TAIR-specific short description
ncbi_gene_idNoNCBI Gene ID from /gaia/aliases/ — None if BAR has no NCBI cross-ref
aliasesNoCross-DB aliases from /gaia/aliases/ (RefSeq accessions, UniProt accessions, TIGR locus-model IDs, and TAIR aliases). Empty list if /gaia degraded.
speciesYes
source_urlYesThaleMine endpoint URL for traceability
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description must disclose behavior. It explains data sources (ThaleMine, GAIA) and the data returned (curator summary, NCBI ID, aliases). It also mentions the tool is 'keyless' and lists taxonomy scope. Lacks explicit read-only statement but is implied.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is fairly long but each sentence adds specific value (purpose, data sources, sibling replacement, taxonomy). Could be slightly more concise without losing information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the presence of an output schema, the description covers input, purpose, data content, taxonomy, and use case entirely. No gaps remain.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The only parameter 'locus' has a description with an example ('e.g. AT1G01010'), adding clarity beyond the schema's type constraint. Schema coverage is 100% so the description adds value.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it 'Fetches the BAR merged ThaleMine + GAIA-aliases summary for an Arabidopsis locus' and specifies the exact data returned, distinguishing it from the older tair_locus_info stub.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description notes it is for 'Arabidopsis only' and that it 'replaces the v0.9 subscription-gated tair_locus_info stub for the curator-summary use case', providing usage context. However, it does not explicitly compare with sibling tools like tair_locus_info or other summary endpoints.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
