Causal Decision Agent

by vikranthviki

rlassologit_effect

Read-only

Estimates the causal effect of a treatment on a binary outcome, using Lasso to select control variables for confounding adjustment.

Instructions

Effect of d on a binary y after Lasso-selecting controls x.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
dYesd parameter (Union[np.ndarray, pd.Series, str]).
xYesPrimary running variable, regressor, or feature input for this estimator.
yYesOutcome variable column name or outcome array.
I3NoAmelioration set forced into the control set (hdm's ``I3``).
postNoPost-Lasso inside the two selection steps.
detailNoPayload depth: 'minimal' (~150 tokens) for sub-step calls where only the point estimate is needed; 'standard' (~1K tokens) for diagnostics + coefficient table; 'agent' (~2K tokens, default) adds violations / next_steps / suggested_functions so the LLM can plan its next call without another round-trip.agent
as_handleNoIf true, cache the fitted result on the server and return result_id + result_uri alongside the JSON payload so a subsequent tools/call can chain without re-running.
data_pathNoAbsolute path or URL to a data file. Supported: .csv / .tsv / .txt (delimited), .parquet / .pq, .feather / .arrow, .xlsx / .xls, .dta (Stata), .json / .jsonl. Schemes: file://, s3://, gs://, https://.
result_idNoOptional handle to a previously-fitted result (returned by an earlier call when as_handle=true). Tools that operate on a fitted object accept this in place of re-supplying data_path + columns.
data_columnsNoOptional column projection. Parquet/Feather/Stata loaders honour this for fast partial reads.
data_sample_nNoOptional uniform random subsample size (seed=0, deterministic) — useful on huge panels.

TDQS

A3.7/5.0
Behavior3/5

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

The `readOnlyHint` annotation already signals that this is a safe read-style operation, and the description adds the useful behavioral context that control selection is Lasso-based and the outcome is binary. It does not disclose details such as which inference quantities are returned or any computational caveats, but the output schema exists and the read-only annotation lowers the disclosure burden.

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

Conciseness5/5

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

A single, front-loaded sentence that packs in the treatment, outcome type, and control-selection method with no filler. Every phrase contributes meaning.

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

Completeness4/5

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

For a tool with 11 parameters, full schema coverage, an output schema, and a read-only annotation, the description supplies the one piece the schema lacks: the statistical role of the required inputs. It is largely complete for invocation, though a brief note on how it differs from `rlassologit_effects` would make it fully self-sufficient.

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

Parameters4/5

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

Schema coverage is 100%, so the baseline is 3, but the description adds real semantic value by assigning roles: `d` is the treatment/exposure variable, `y` is the binary outcome, and `x` are the controls. This is especially helpful because the schema entry for `d` only says 'd parameter (Union...)' and does not explain the causal role that `d` plays.

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

Purpose4/5

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

The description clearly identifies the estimation target — the effect of treatment `d` on binary outcome `y` while Lasso-selecting controls `x` — which goes well beyond a tautology and gives an agent the core model setting. It does not explicitly use a verb like 'estimates' and does not contrast itself with the closely related sibling `rlassologit_effects`, so it stops short of full sibling differentiation.

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

Usage Guidelines3/5

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

The intended setting is implied: binary outcome, a treatment variable `d`, and controls selected by Lasso. However, the description gives no explicit 'use this when...' guidance and names no alternative tools, even though siblings like `rlassologit`, `rlassologit_effects`, and `rlasso_effect` exist in the same family.

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