Works with
Verifying Cursor Output
Last updated: 2026-07-024 min read
Reality Graph is a local-first verification layer that works beside Cursor: a written task with boundaries before the agent run, independent validation and an evidence report after it, a human gate before merge. Cursor stays your coding agent – including Bugbot and its built-in review surfaces. Verification adds the one reference none of them have: your written intent.

Why Cursor runs deserve verification
Cursor’s agent reads the codebase, edits across files, runs commands and iterates on failures – and the 2026 additions moved that work progressively off-screen: background agents run while you edit something else, cloud agents run off your machine entirely, and subagents parallelize within a task (product state: July 2026). Every one of these is a productivity feature, and every one removes a moment where you would incidentally have watched the change happen. What remains constant: the agent’s summary of its work is written by the model that did the work, and with only 48% of developers consistently verifying AI code, unwatched volume is where the gap grows.
The verification workflow around a Cursor run
- Before the run: write the task. Goal, boundaries (what the agent may touch), acceptance criteria – in checkable form, not in the prompt box only. The prompt disappears into history; the task is the reference verification needs.
- After the run: compare diff to task. Scope first – files outside the boundaries are findings, however good the code. Then criteria. Cursor’s diff view is the right surface for reading; the task is the reference for judging.
- Validate independently. Tests, types, build – authored outside the generating session. An agent that wrote its own tests and passes them has confirmed itself, not the requirement.
- Human gate. A person reads the evidence and decides. Background and cloud agents make this the only moment a human is guaranteed to see the change – protect it.
Cursor-specific risk points, mapped
| Risk point | Why it bites | Countermeasure |
|---|---|---|
| Accept-all on multi-file diffs | Composer edits span many files; fatigue normalizes bulk-accepting | Boundaries in the task; scope check before reading a single hunk |
| Background/cloud agents | Work completes unwatched; summary is self-authored | Verification per run instead of trust per notification |
| Subagent parallelism | Multiple workers widen the blast radius per task | One written task per run; boundary check covers all workers |
| Bugbot as the only check | Reviews diff quality, not conformance with your task | Keep Bugbot; add the spec comparison it cannot run |
The Bugbot row deserves its honest footing: it is a capable reviewer, and pairing it with agent runs is better than nothing by a wide margin. The structural limits – diff-only reference, and the measured self-preference of LLM evaluators when generator and reviewer are the same kind of model – are examined in why self-review is not enough.
Where Reality Graph fits
Reality Graph adds the layer Cursor does not claim to provide: each run gets a written task with boundaries, the change is verified against it with validation the model did not author, and the outcome lands in an evidence report – local-first, so the verification layer itself adds no new cloud data flow. It works the same beside Claude Code and GitHub Copilot – Cursor is simply the tool this page is about.
Beside Cursor, verification gives you
- A reference the agent did not author: your written task
- Scope and criteria checks that survive background runs
- Evidence per run for reviewers and audits
- The same loop across every other AI tool you use
It does not
- Replace Cursor - it stays your coding agent
- Replace Bugbot or human review - it feeds both
- Slow the run - structure before, checks after
- Come from Anysphere - Reality Graph is independent

FAQ
- How do you make sure Cursor-generated code is correct?
- With a check that does not depend on Cursor's own account of its work: a written task with boundaries before the agent run, a comparison of the produced diff against that task afterwards, validation (tests, types, build) that the generating model did not author, and a human decision before anything reaches a shared branch. Cursor's diff view and checkpoints support this workflow well - what they cannot provide is the independent reference, because the task lives in your head unless you write it down.
- Doesn't Cursor already review its own work with Bugbot?
- Bugbot is a genuinely useful reviewer, and running it on agent PRs catches real bugs. Two limits remain: Bugbot reviews the diff against general quality standards, not against your specific task - well-built changes that do the wrong thing pass any quality-only review - and generator and reviewer being frontier LLMs raises the shared-blind-spot question research has measured. Keep Bugbot; add a reference it does not have.
- Is Reality Graph a Cursor or Anysphere product?
- No. Reality Graph is an independent product by Philogic Labs, not affiliated with Cursor's maker Anysphere. It works beside Cursor the same way it works beside Claude Code or GitHub Copilot - as a tool-agnostic, local-first verification layer. Cursor stays your coding agent.
- What changes with background agents and subagents?
- Volume and attention. A foreground agent run happens while you watch; background agents (and the subagents Cursor added in 2026) work while you do something else, which is the point - and which removes the incidental review that watching provided. The more work moves off-screen, the more the write-task-first, verify-after pattern carries: it replaces attention you no longer pay with checks that run regardless.
- How do teams use Cursor safely without extra tooling?
- Five habits carry far: write the task down with boundaries before agent runs instead of prompting from memory; keep runs small enough that the diff is reviewable; use checkpoints and the diff view deliberately rather than accept-all; keep tests the agent did not write in the loop; and never let anything auto-merge to shared branches. A verification layer systematizes these habits - it does not replace them.
- Does verification slow Cursor down?
- The run itself is untouched - structure is added before it (a written task, minutes) and checking after it (largely automated). What teams actually report losing is the rework loop: changes that did the wrong thing correctly used to surface in review or production; with a spec comparison they surface immediately, while the context to fix them is still loaded.
