How Skills Ensure Accuracy, Quality, and Reliability
Last updated: March 9, 2026
Skills are designed for consistency and accuracy. The platform uses several specific mechanisms to ensure that outputs are trustworthy, traceable, and defensible — whether preparing an IC memo, reconciling a rent roll, or producing reporting for investors.
How Skills Ensure Accurate Output
Process-driven execution. A Skill follows the exact steps defined, in the same order, every time. There is no variation between runs — the same documents and the same Skill will always produce the same approach. A lease abstraction Skill built to extract 15 fields in a specific sequence will do exactly that on every lease run through it.
Deterministic calculations. All numerical work — formulas, aggregations, comparisons — is performed through verified calculations, not estimated or approximated. When a Skill calculates NOI, the numbers are computed, not generated. This is a critical distinction for financial workflows.
Automatic error handling. If something unexpected occurs during execution — missing data, an unexpected format, a field that does not match the expected structure — the system identifies the issue and attempts to resolve it automatically before producing output. The result is never a silently wrong answer.
Verification built in. Well-designed Skills include verification steps: cross-checks, sanity checks, expected ranges, and reconciliation logic. When creating a Skill, Ellie will proactively encode these checks into the process. For example, a rent roll reconciliation Skill might cross-check total contracted rent against the sum of individual unit rents and flag any discrepancy.
Iterative refinement. Most Skills benefit from a few rounds of testing to handle edge cases well. This is by design — each round strengthens the Skill. The first pass gets the core process right, the second handles formatting and edge cases, and the third catches nuances specific to the data.
Firm expertise encoded. The quality of a Skill reflects what is built into it. Industry-specific terminology, business rules, standard formulas, and known edge cases are all captured during creation and applied consistently across every run. A Skill configured to calculate WAULT excluding renewal options will do so every time, without being reminded.
💡 Tip: When creating a Skill, ask Ellie to include verification steps — cross-checks, expected ranges, and reconciliation logic. These get built into the Skill and run automatically on every execution.
Every output is traceable back to the source data and the logic applied. The platform shows its reasoning — which fields came from which documents, what calculations were performed, and how conclusions were reached. This makes decisions auditable and defensible.
What Skills Are Most and Least Reliable For
Not all tasks are equally suited to Skills. Here is a practical guide to where Skills perform best and where a different approach may be needed.
Most reliable — high confidence from the first or second iteration:
Single-pass tasks with clear inputs and outputs: extracting specific fields from an executed lease, reformatting a rent roll into a firm's standard template, populating a deal screening checklist, classifying incoming documents by type.
Multi-step tasks cross-referencing a few sources: comparing in-place rents on a rent roll against lease terms and flagging discrepancies, calculating NOI from operating statements and formatting a summary report, validating actual expenses against a budget line by line.
Reliable with iteration — typically needs a few rounds of refinement:
Tasks with conditional logic and multiple calculation paths: scenario-based financial modelling with different hold periods, compliance reviews with many exception rules, multi-property portfolio analyses where each asset type requires different treatment, waterfall distribution calculations with promote tiers.
Less suited for a single Skill — consider breaking down:
Tasks requiring open-ended judgment across many documents with no clear criteria.
Processes with many conditional branches that each require professional judgment.
Workflows requiring access to live systems or data not available in the attached documents (though Skills can query connected data sources at runtime for systems that are integrated).
ℹ Note: Even tasks in the "less suited" category usually contain repeatable sub-steps that work well as Skills. A complex acquisition underwrite may require judgment, but the rent roll extraction, expense analysis, and comp formatting within it are all strong Skill candidates. Ellie can help identify the procedural parts and separate out the judgment-dependent parts — let the Skill handle the preparation and let the team focus on the decisions.
