Reduce Minimize

by Software Failure Reduction Lab in Developer tools

x402 APIPassing, checked 3 h ago

Given a source bundle, entry file, command, and failure predicate (exit code and/or stdout/stderr patterns), runs a deterministic delta-debugging reducer in a network-isolated sandbox and returns the reduced bundle and entry that still reproduce the failure, plus a replay script and run log. Scoped to a local minimum under the passes listed, never a proof of global minimality.

Parameters

Parameter	Type	Required	Description
`bundle`	string	Yes	Base64 .zip of the bundle: source files and inputs (<= 2097152 bytes decoded), no symlinks, no absolute paths, no ".." entries.
`command`	array of string	Yes	Command run from the bundle root; argv[0] must be one of node, python3, sh.
`entry`	string	Yes	Relative forward-slash path inside the bundle of the file to reduce textually (<= 524288 bytes, UTF-8 text).
`language`	string	No	Language hint for structure-aware passes; "auto" sniffs from the entry's extension. One of: auto, text, json, javascript, typescript, python, c-like. Default: "auto".
`maxRuns`	integer	No	Upper bound on candidate executions. Default: 400.
`predicate`	predicate	Yes
`pruneFiles`	boolean	No	Whether files other than the entry may be deleted when the failure survives without them. Default: true.
`timeoutMs`	integer	Yes	Per-run wall-clock limit in milliseconds.
