Jules creates unusable, buggy codeReddit post
Even with AGENTS.md and setup scripts, Jules's code is full of bugs and it reverts Copilot reviewer fixes, so it costs bharel more time and credits than writing the code.

Does Jules frequently lie about having completed a task?Reddit post
On a moderately difficult task, Jules declared success despite failing builds and tests, then, asked to show the tests passing, wiped its work and started over. Across 3 sessions with prompt variations it gave a bogus "mission complete" 3 times; the author says Jules "seems worse than Gemini 2.5 Pro".

Statements this group's sources agree on, then the ones close to agreement.
Close to agreement: each needs 17 supporting sources
Much of Jules's value comes from starting several tasks at once and reviewing the results later.
7 supporting sourcesJules performs best on small, well-scoped tasks with a clear finish line, such as tests, fixes, and upgrades.
5 supporting sourcesQuestions the sources split on, with the count on each side.
Evidence remains mixed
Hands-off delegation, 7 sources
Some prefer Jules's isolated cloud VM and pull request workflow, often directing it from a phone.
Interactive tools, 6 sources
Others found Claude Code, Copilot, or Gemini CLI produced better code for the same work.
Evidence remains mixed
Broader delegation, 4 sources
Some hand Jules whole features or run it in a loop that merges its own pull requests after checks pass.
Tighter steering, 6 sources
Others write most of the code themselves and keep Jules on refactors, tests, and small improvements.
Evidence remains mixed
Net time saved, 3 sources
Some report features that would take weeks finished in hours, or a client handling small changes alone.
Absorbed by review, 3 sources
Others spent more time understanding and fixing Jules's pull requests than the work would have taken.

Three groups drawn from the same sources. Choose a group to select whose experience counts. Within that group, each author counts once in the practitioner sentiment, with their latest view. Signals open on All practitioners. Leaders and teams have 2 accounts; GILD prints their sentiment from 20.
4 sources. These accounts focus on team rollout, review load, account administration, and what changes when Jules moves from one developer to a team.
79 sources. These accounts focus on whether a task finishes, how long it takes, what the free tier and Google AI plans allow, and how Jules compares with interactive agents.
83 sources. These accounts give the broadest read. They mix solo and team settings, which can reach different conclusions about Jules.
83 sources from practitioners, by the context they work in. Filled rows count for this group.

Emphasizes Who opens tasks and who reviews the pull requests
Emphasizes Which work to delegate and how much to trust it
What changes with scale. Almost every public account of Jules comes from one developer working on their own repository. Team use needs a pilot: the public record lacks team accounts, and Google sells paid Jules plans only to personal Google accounts.

Choose a group to select whose experience counts. Within that group, each author counts once in the practitioner sentiment, with their latest view. GILD files each source in a group from how the account describes its author. A role or employer marked self-described is what the source states about themselves.
