The comparison found no +correctness advantage on the selected tasks, while recorded tokens increased. +Useful documentation and useful automatically loaded instructions are not +the same thing. + +## What was compared + +The completed comparison used public **pytest-skill-engineering 1.0.3**, +`github-copilot-sdk` **1.0.16**, `mcp` **2.2.0**, and **gpt-6.1-sol**. +Six tasks, two entry points, skill/no-skill conditions, and two repetitions +produced **48 unique cases**. Requests, tools, permissions, fixtures, model, +and budgets were held constant within each entry point. Only the matching +skill's availability changed. + +Four tasks used pinned public SpreadsheetBench workbooks: grouped transaction +totals, monthly inventory comparison, last-record deduplication, and conditional +date/text totals. Two authored tasks repaired Power Query and refreshed an +existing Data Model/DAX/PivotTable/PivotChart report. This was an adapted pilot, +not an official SpreadsheetBench score. + +The input revision was `49b73a94775fb489063f60ca1865e3a650079a79`; the archive +SHA256 was `10ef893dd29cb13ab97143ea787e68cdc9574a13873ab9a54e50b31dc03fc949`. +SpreadsheetBench declares CC BY-SA 4.0. No upstream workbook, answer file, or +adapted benchmark instruction is included in this example. + +## Evidence, not completion claims + +Fixed checks ran outside the model-writable task directory. They reopened +saved workbooks through desktop Excel COM, checked every requested result, +and protected unrelated values, formulas, formats, calculation mode, and +named analysis objects. Formula cases also changed inputs to reject constants +that happened to match the original answer. + +Before paying for comparisons, checker proofs rejected unchanged or deliberately +incorrect workbooks. Model prose and successful tool calls alone could not pass. +Missing correlated completion evidence was a capture failure, not a task success. + +An early lesson was that supplying a skill directory did **not** establish +availability. In the SDK's isolated `empty` mode, skills needed explicit +`enable_skills=True`. Each real directory was validated with public `load_skill`, +then SDK discovery checked the exact enabled name and resolved source path. +Discovery probes forbade `send` and `send_and_wait`; they made no model requests. +Actual treatment calls separately established that the skills were read. + +## Measured result + +| Entry point | Without skill | With broad skill | Correct cases per condition | +|---|---:|---:|---:| +| MCP | 4,312,584 recorded tokens | 5,320,118 recorded tokens | 12/12 | +| CLI | 1,794,556 recorded tokens | 3,092,967 recorded tokens | 12/12 | + +Recorded token usage increased **23.4% for MCP** and **72.4% for CLI**. +All **24 treatment cases read the matching skill**. This was not a +missing-treatment result. + +The resumed round reserved **50 of 100 authorized attempts**: 48 verified +unique cases and two interrupted reservations. Interrupted usage is unknown, +excluded from those percentages, and never represented as zero. Earlier +package-1.0.2 comparisons had a separate allowance and are not pooled here. + +The [compact receipt](https://github.com/sbroenne/pytest-skill-engineering/blob/main/examples/excel-skill-value/evidence/real-world-1.0.3.json) +preserves case metrics, frozen hashes, and invocation boundaries without private +workbook paths or raw conversations. + +## Limits and the recording problem + +One capable model, six tasks, and two repetitions do not establish universal +skill value. Repeated cases reused input contents; public cases may already be +known to the model. Equal success creates a ceiling: there is no observed +correctness difference to estimate. + +The runner resumed across three invocations and a recorder-code change. +Two interrupted runners returned no final result; their cause was not proven. +The recorder later saved returned execution before workbook verification and +used atomic attempt snapshots. Those protections worked. The configured public +`on_event` callback received **zero live events** in the actual comparison. +Mocked callback tests are not evidence that live journaling works. + +## Product decision + +The broad default skills were replaced by two optional report-formatting +skills. General workflows, limitations, recovery, and command references moved +to ordinary documentation, with the existing website addresses preserved. +The `skills` directory now contains actual skills, not a documentation corpus. +Native schemas/help and recovery messages remain responsible for product +behavior and essential safety. + +This decision is supported for the tested model and tasks. It does **not** +establish that the new narrow skills help. Their separate, unrun comparison has +positive formatting tasks and ordinary non-trigger tasks; it checks selection, +workbook correctness, and usage separately. + +## Small runnable example + +The [Excel example](https://github.com/sbroenne/pytest-skill-engineering/tree/main/examples/excel-skill-value) demonstrates the +method with one self-authored workbook task, both entry points, and paired +skill/no-skill cases using the public 1.x API. Its frozen broad fixtures match +the historical manifests. A formatting-profile run instead uses explicitly +supplied prepared narrow skills and must not be pooled with the broad result. + +The example does **not** reproduce the full 48-case workload or promise the +same token percentages. Default tests are offline. Desktop-Excel checker +proofs and paid live comparisons are separate commands. No new live example +run was used to support the historical conclusion. diff --git a/examples/README.md b/examples/README.md index 3ce1e13..b1928e9 100644 --- a/examples/README.md +++ b/examples/README.md @@ -14,6 +14,13 @@ Its harder checkout workflow adds durable state, duplicate/conflicting requests, and 42 fixed checks.

There is no tool-level undo for discarded edits. +- Cancellation is not undo. After failure, inspect the surviving session and + affected objects before retrying.

If the session was removed or invalidated, do not call `set-mode`; +report that restoration could not be completed. Do not blindly reopen the +workbook or repeat writes. +Reads and operations needing intermediate results do not need manual mode. +Value/formula writes attempt to restore the prior mode rather than always +forcing calculation. Restoration can fail without failing the write; use +`get-mode` when subsequent work depends on the mode. Automatic normally +recalculates dependent formulas after restoration; manual needs explicit +calculation. Semi-automatic excludes what-if data tables, not ordinary worksheet +Tables.

These formulas follow fixed source rows: after a sort or source +growth, recheck the mapping and extend the helper and chart source as needed. +Do not silently replace an existing growing Table source with this fixed range. + +## Readable periods in chronological order + +Displaying a timestamp as a month does not aggregate the transactions. Use a +period summary when the requested trend needs monthly, quarterly, or yearly +values. Keep real dates as the period keys, display month/quarter/year labels, +and order by those dates rather than alphabetically by label. Keep the year: +December 2025 and January 2026 are consecutive periods, not a month-name sort. +State whether values are sums, counts, averages, or another measure; do not +average percentages without considering their denominators. + +For an existing `Transactions` Table with native Excel `Date` values and numeric +`Revenue`, use an empty `Summary!A1:B3`.

Include missing periods where the trend requires them; +`SUMIFS` returns zero with no matching rows, which is appropriate only when +absence means no activity, not unknown or incomplete data. Do not disguise +missing data as zero; choose the chart's blank-cell behavior deliberately. + +For an interactive trend, summarize in the existing regular PivotTable instead. +For example, `RevenuePivot` already has native-date `Date` in Rows and Sum of +`Revenue` in Values.

Date grouping requires valid dates without blank/error +items and is not supported for Data Model PivotTables.
