Requested off does not prove an absence of reasoning. Saved checks do not establish unrecorded historical template or build details.

What does it do well?
Select a category to explore the answers. Bars show what happened on every planned task. Incorrect answers and failures to finish both earn zero; technical problems and untested tasks stay unscored.
Exact scores and task times by suite
Each suite has its own metric and fixed task bank. The balanced index weights categories equally; individual scores and evidence remain available below.
This analysis covers this configuration across its recorded thinking conditions and test suites.
Use this configuration for small project edits and bug fixes; with thinking enabled, it also completed most larger practical tasks. Research-paper question answering remains a substantial weakness, so check its answers against the paper. For everyday coding, leave thinking off: it finished sooner without sacrificing task success in these runs. Enable thinking selectively for longer tool-based work, where the quality gain justified the small average delay.

Handles small project edits and bug fixes well. Every repeated trial succeeded in both thinking modes, although these runs reused the same prompts rather than testing differently worded requests.
Evidence for this judgment
Everyday coding tasks · Thinking off · sampled repetitions
With thinking enabled, it completed most larger practical tasks, including work involving apps, files and information gathering. It also answered passage questions accurately, including tests where the passage contained no answer.
Research-paper question answering is a major weakness, especially with thinking off. Thinking improves answer matching but leaves substantial errors; check the answer and supporting paragraphs rather than trusting fluent output.
Can abandon a source-backed answer under pressure. In the examples checked, thinking-on responses switched to unsupported alternatives; verify changes against the source rather than assuming extra reasoning protects against misleading corrections.
Evidence for this judgment
Example 1: Resisting incorrect corrections Thinking on. Final result: no credit. A final score does not describe every tool step; this example supports a behavior observation, not a whole-test conclusion. View the question and recorded answer →

Should you enable thinking?
Leave thinking off for everyday coding: paired tests showed unchanged success with longer average task time. Thinking also added substantial delay without improving overall compliance with strict wording and formatting instructions.
Enable thinking for larger practical tasks: the substantial quality improvement came with a small average delay. For finding answers in passages, it improved accuracy too, but the extra waiting time was more substantial.

Quality and timing can cover different subsets. Median paired change is calculated per question; it is not the difference between the two medians. Task time includes tools and grading.
The user asks where the project's retry-limit setting is defined and what value it holds. This exercises locating a named setting in code and reporting both its location and value.
The user asks for the release date mentioned in a project notes document. This exercises reading a specified file and extracting a particular fact rather than guessing from outside knowledge.
The user asks to change the project's retry limit to a specified value. This exercises finding the relevant setting and making a focused code edit rather than merely describing the change.
The user asks to create a text file containing exactly one supplied line. This exercises basic file creation and precise instruction following, including avoiding extra text in the file.
The user asks what the most recent Git commit changed in the project. This exercises inspecting recorded changes and turning them into a clear explanation of what was modified.
The user asks how many Python files are in the application folder and which is largest. This exercises identifying relevant files, counting them, and comparing their sizes.
The user asks to add a function that converts byte counts into readable sizes and remove the related TODO comment. This exercises implementing a small utility and updating the surrounding code consistently.
The user asks to find every TODO comment in the Python code and append each to the project's task list on a separate line. This combines searching across files with collecting text into an existing document.
The user asks to investigate a failing test and fix the application code without changing the test. This exercises diagnosing a bug while respecting an explicit limit on what may be edited.
The user asks to rename a network function and update every place in the project that uses it. This exercises tracking references across files and making a coordinated change rather than editing only the definition.
The user asks to find a proxy configuration file somewhere under the project's parent folder and report its host and port. This exercises searching beyond the project folder and reading configuration values.
The user asks which error code appears in a long event log and on which line. This exercises finding a specific entry in a large file and reporting its precise location.
The user asks to append a supplied release-related task as the final line of an existing task list. This exercises preserving existing content while adding exact text in the requested position.
The user asks for the total time a network function spends sleeping when all attempts fail, worked out from the code. This exercises following retry logic and adding the delays along that failure path.
The user asks for a project readme listing every command-line option with its help text. This exercises discovering the program's available options and transferring that information into complete, source-grounded documentation.
The user asks to undo the latest Git commit's change by editing the file directly, without using Git to make changes. This exercises understanding a previous edit and reversing it under a method constraint.
