# Recursive Language Models Explained

A mobile-first explainer of the Recursive Language Models paper through the lens of a Salesforce consultant investigation.

This public explainer keeps the page custom-designed while still exposing a structured markdown version for AI agents, search systems, and downstream reuse.

## Consultant investigation

The story frame is a messy Opportunity stage-change investigation across requirements, Flow, Apex, validation rules, history, and incident notes.

- Business notes: Partner-led approvals changed the expected stage path — The intended business rule spans multiple artifacts, so no single prompt-sized summary is enough to preserve the full constraint.
- Flow: Flow updates Opportunity stage after approval status changes — The Flow is one mutation path and confirms that approval completion can trigger a stage update for partner deals.
- Apex: Apex trigger adds a second stage mutation path — A second mutation path explains why the issue cannot be solved by reading only the Flow branch.
- Validation: Validation rules encode assumptions from the old process — The investigation needs cross-artifact reconciliation rather than a shallow scan of one rule.
- Field history: Audit trail shows stage flips after approval completion — Temporal evidence confirms that the Flow writes first and Apex applies a second legacy recalculation immediately after.
- Incident notes: A prior hotfix changed one path but not the other — Past context is another artifact to inspect, not something to compress into the root prompt upfront.
## Root model objective

The explainer behaves like a guided console: inspect a promising artifact, recurse into its local context, decide whether the finding deserves memory, and only then unlock synthesis.

- Business notes: Start with the business rule to understand what a correct stage path should look like before inspecting automation. Focus: Clarify which combination of approval and compliance events is supposed to allow stage advancement.
- Flow: Inspect the Flow first because it bridges the business event and the stage mutation the user can see. Focus: Trace the approval-status branch and the partner conditions that decide whether the Flow writes a new stage value.
- Apex: Inspect Apex next because the Flow alone does not explain the duplicate stage flips visible in field history. Focus: Check whether legacy partner metadata triggers a second recalculation after the Flow has already written a stage.
- Validation: Inspect validation if the automation paths are still ambiguous or if business expectations conflict with the writes. Focus: Compare the old intermediate-stage rule with the newer partner approval path.
- Field history: Inspect history after Flow and Apex because temporal evidence can reconcile which path fired first. Focus: Match timestamp order across approval completion, Flow write, and Apex recalculation.
- Incident notes: Inspect incident notes when you need historical context on why one branch diverges from expected behavior. Focus: Check whether the prior fix touched the Flow path, the Apex path, or both.
## Final synthesis

The unexpected stage change comes from two competing automation paths: the Flow advances the Opportunity after approval completion, then a legacy Apex recalculation applies a second partner rule set.

- Consolidate the stage-change logic into one source of truth, retire the legacy Apex path, and update the validation rule to match the intended partner approval process.
- Best for layered evidence: RLMs shine when the answer depends on interactions across multiple artifacts, not just locating one hidden fact.
- Think investigation, not ingestion: The key shift is from fitting everything into one prompt to navigating an environment with deliberate recursive steps.
- Working memory matters: Symbolic findings let the model accumulate understanding without repeatedly compacting the whole case.
- Use direct prompts when the task is simple: If the work is short, local, or mostly retrieval, recursive orchestration can cost more than it helps.
