Fork a signal into an inactive parameter variant — production firing is untouched. Experimentation primitive: fork, dryrun-backtest, then activate. Returns the new version id and parameters. Runs acr…

Deep-merge an ordered list of JSON documents, left to right. Objects are merged key-by-key; arrays, scalars and null in a later document replace the earlier value (last-wins, no array concatenation).

Evaluate a JMESPath expression against a JSON value and return the selected/projected result. A malformed expression is rejected before payment.

Apply an RFC 6902 JSON Patch to a JSON document and return the result. An invalid or unresolvable patch (e.g. a failed `test`, or a path that does not exist) is rejected before payment.

Compute the RFC 6902 JSON Patch that transforms `source` into `target`. The patch is a minimal array of add/remove/replace operations.

Every model on the OpenRouter marketplace with per-million-token input and output pricing, cached-input rates where published, and context windows: several hundred rows, rebuilt daily. A changes block diffs each build against the last: models added, models dropped with their last known figures, and every price or context-window move as from/to. How much moved is free: this listing carries the build's added, removed and repriced counts, so a quiet day can be skipped unpaid.

database migration risk scan for SQL migrations: flags destructive statements, unbounded updates and risky NOT NULL column additions.

Batch safety preflight for many database migrations at once: a list of objects each with a name and migration SQL. Returns a per-file pass, caution or block verdict plus a rollup with the worst verdict and counts. Migration-safety indicators, not a guarantee.

Safety preflight for a database schema migration BEFORE you apply it. Send the migration SQL for Postgres or MySQL and get a pass, caution or block verdict with per-finding operation, severity, plain-language reason and a zero-downtime alternative. Migration-safety indicators, not a guarantee.

Check agent outputs for quality issues, inconsistency, and behavioral drift.

Weighted interval scheduling solver — exact maximum-weight compatible job scheduling with half-open intervals and a complete dynamic-programming certificate.

Compare bounded room requirements with supplied topology; report unknown and contradictory declarations, not architectural approval.
