Dimension	Result	Detail
Scientific Integrity	PASS	No fabricated values, significance levels, trends, or PMIDs produced. Hard rule 6 explicitly prohibits fabricating statistical significance or dataset features. Hard rule 5 prevents selective positive-bias narration.
Practice Boundaries	PASS	No diagnostic or prescriptive clinical conclusions. Estimate boundary rules keep wording aligned with table type (descriptive vs. associative vs. causal).
Methodological Ground	PASS	Hard rule 3 prevents converting descriptive tables into causal claims. Hard rule 4 prevents overinterpretation of subgroup tables. Estimate boundary rules enforce association vs. causation distinction.

Core Capability93 / 100 — 8 Categories

Functional Suitability

Nine table types covered (baseline characteristics through supplementary tables). Five table-type-specific narration strategies (baseline, regression, subgroup, model-performance, sensitivity). Seven-step workflow + eight-section output (A–H). 'Smallest set of values needed' principle prevents row-by-row repetition. Hard rule 5 (never hide null findings) is an unusual and important integrity safeguard.

12 / 12

100%

Reliability

Clarification-first gate + upload recommendation. Section C (Main Narrative Message) forces explicit table-contribution identification before narration begins. Hard rule 2 prevents number-repetition. Minor deduction: no partial-output mode when table context is sparse but user asks to proceed.

11 / 12

92%

Performance & Context

Full marks. Seven compact reference files. SKILL.md 263 lines. Section D (Prose-Worthy Points) and Section E (Table Narrative Draft) are cleanly separated — D selects, E implements. No redundancy between sections. 'Smallest set of values needed' principle also reduces output token cost.

8 / 8

100%

Agent Usability

Full marks. Six sample triggers, eight-item core function list, quality standard comparison. Eight fixed A–H section labels. Five feedback mechanisms across Sections A, C, D, F, G, H. Section C explicitly states table contribution before any narration — prevents purposeless writing.

16 / 16

100%

Human Usability

Six sample triggers and quality standard comparison make entry points clear. Section H + upload recommendation guide next steps. Minor deduction: no explicit restart path when user provides additional table context after initial narration.

7 / 8

88%

Security

No credentials, APIs, or code execution. Hard rules 1 and 6 prevent inventing values or significance. Hard rule 5 prevents selective positive-only narration (a form of scientific misrepresentation). Estimate boundary rules enforce evidence-level constraints in prose.

12 / 12

100%

Maintainability

Seven focused reference files; adding a new table type (e.g., competing-risks table) requires only updating table-type-specific-rules.md. Clean separation between message extraction, narrative selection, estimate boundary, and type-specific rules. Minor deduction: no worked example for any specific table type.

11 / 12

92%

Agent-Specific

Trigger precision: six specific triggers plus clear 'not for' scoping (4/4). Progressive disclosure: clarification gate + Section A + Section H (3/4 — no multi-level decision fork). Composability: no explicit hook to results-section-writer for embedding narrative in Results section (2/4). Idempotency: A–H structure stable (4/4). Escape hatches: Section H + upload recommendation (3/4 — no partial-output mode when table context is sparse).

Canonical✅ Pass

Table 1 baseline characteristics for an RCT with 8 variables across treatment and control groups

All five assertions passed. Table type correctly identified. Baseline comparability emphasized. Minor imbalance flagged without overinterpretation.

Basic 36/40|Specialized 52/60|Total 88/100

✅A1Output correctly identifies Table 1 as a baseline characteristics table and applies appropriate narration strategy

✅A2Output focuses on overall group comparability rather than narrating every row

✅A3Output does not overinterpret minor baseline differences as clinically meaningful

✅A4Section G states that baseline differences must not be used to claim confounding in Results

✅A5Section D lists only the 2–3 most meaningful contrasts for prose mention

Pass rate: 5 / 5

Variant A✅ Pass

Multivariable logistic regression table with 6 predictors, primary predictor significant, 3 covariates null

All five assertions passed. Regression narration correctly leads with primary predictor. Null covariates correctly left in table without prose emphasis.

Basic 37/40|Specialized 52/60|Total 89/100

✅A1Output leads narrative with the primary predictor estimate and confidence interval

✅A2Output does not narrate every covariate row individually

✅A3Output does not upgrade the association to causal language

✅A4Hard rule 5 verified: null covariate findings are not hidden from the narrative

✅A5Section G states the narrative must not imply the association is independent of all possible confounders

Pass rate: 5 / 5

Edge✅ Pass

User says 'here is my table' but attaches no actual table or column definitions

All five assertions passed. Clarification-first gate triggered. No fabricated narrative produced.

Basic 39/40|Specialized 55/60|Total 94/100

✅A1Output triggers clarification-first gate and requests the table before narrating

✅A2Section A states explicitly that input is insufficient for any narrative

✅A3Output does not fabricate a generic table narrative from the absence of a table

Basic 37/40|Specialized 52/60|Total 89/100

✅A1Output explicitly distinguishes pre-specified from post-hoc subgroups in the narrative

✅A2Output does not narrate all 15 subgroups individually

Basic 37/40|Specialized 50/60|Total 87/100

✅A1Output correctly identifies AUC as the primary metric for narrative emphasis in a discrimination model table

✅A2Output does not narrate all 48 metric-model combinations individually

✅A3Output does not conflate model AUC with clinical usefulness

Medical Task Total90.3 / 100

Key Strengths

Hard rule 5 (never hide null or mixed findings by selectively narrating only positive rows) directly prevents the most dangerous table narrative failure mode — selective positive-bias
Five table-type-specific narration strategies (baseline, regression, subgroup, model-performance, sensitivity) correctly adjust emphasis for different table functions
'Smallest set of values needed' principle enforces prose selectivity and prevents redundant numeric repetition
performance_context score of 8/8 — the cleanest section architecture of all Academic Writing skills reviewed, with no structural redundancy
Section C (Main Narrative Message) requires explicit table-contribution identification before any narration — prevents purposeless or reflexive row-by-row writing
