Parallax
Using it
The lenses, the line a sweep leaves in your terminal, and where each part is explained in full.
When a session ends
A Stop hook, an explicit end, or thirty quiet minutes, and the door sweeps the session: it proves the agent’s own edits in a sandbox, reviews the transcript, forks the implementation turn to router-picked seats from other labs, re-runs the proven tests of the other sessions on the same files, runs the lenses below with a proof for each finding, scans for dead code, and delivers. Each step and what it can say is on Sessions.

| lens | asks | proof |
|---|---|---|
bugs | what is wrong that the existing test did not check? | the new test fails without the fix and passes with it; the full-suite result is reported separately |
security | what could an attacker use? Asked together with bugs as one question per shard | the same reproduction, with a severity; a mechanical pass first, free |
perf | a faster, simpler or smaller way? | a benchmark on each side, or fewer branches; suite green |
hygiene | what was left behind? | static first: an edit may only remove or reword, never add a branch or a call; then the suite is green with the cleanup |
drift | which document now says something untrue? | the referent is really gone; a one-line prose fix |
dead code | what does nothing reference? | each removal proven alone and together; no model call |

On a pull request
When automatic PR review is enabled or a review is explicitly requested, one check, Parallax, carries a first pass in minutes and a deep pass after it. Automatic PR review is off by default (PARALLAX_PR_REVIEW=on enables it). Findings carry an evidence state and a confidence. The deep pass offers eligible proven and suite-green patches as one-click suggestions, with at most three inline threads; housekeeping findings remain outside those threads. Admitted patches share one fix PR per review. Unverified and could-not-run findings remain in the summary and console; refuted patches and patches that regress the suite have neither a one-click suggestion nor a fix PR. What each label means, the exact rules, and the sections of the comment are on What a review means.
Memory
A proven finding, a merged fix, or a suggestion you applied becomes a lesson for the repository, and the next session that touches that file is handed it. A suggestion you dismiss becomes a suppression. What a lesson is, what is injected, and how to see the receipts are on Memory.
What it costs
The Parallax app is a monthly plan, with unlimited DeepSeek and unlimited GLM on every plan. Plans lists the price and API credit of each.
A new account gets 5 free episodes. Each new episode after that uses one Parallax credit when its review starts. Retrying a failed review, fixing its findings, and rechecking the same episode use no extra credit. The free episodes are a lifetime allowance for the account. See Episode credits for your remaining allowance, current prices, and available packs. Parallax credits are separate from Conifer gateway credits.
