# Atlas decision tracking > The Atlas Decision Ledger tracks decisions in two states, open and settled, surfacing forgotten open decisions and injecting settled ones into context so they are not re-litigated. The Atlas Decision Ledger tracks decisions in 2 states: open, meaning a decision you still need to make, and settled, meaning one you made along with why. Its headline job is surfacing the open decisions you forgot were pending, oldest first, so a question that was quietly blocking progress actually gets decided. Settling one writes an ADR file into your repository and injects it into future sessions so the agent does not re-argue it. The engine ships today behind the paid tier, and Atlas Pro is not yet on sale. ## Key takeaways - Built and running in Atlas. Included in the paid tier, which is not yet on sale. - Tracks open decisions as well as settled ones, not just a log of what was decided. - Shows open decisions oldest first, so the forgotten ones surface rather than the loud ones. - Settling writes decisions/NNNN-slug.md into your repo as a git-tracked ADR. - Settled decisions are injected into session context so the agent stops re-litigating them. ## The decisions that hurt are the open ones The costly decisions are not the 1 you made last week, they are the ones you needed to make and forgot were open. The Decision Ledger keeps open decisions visible and aging-aware, ordered oldest first, so a question raised on a call does not stall the work indefinitely. The ordering matters: a digest sorted by recency shows you what you already remember, while one sorted by age shows you what you forgot. ## Settled decisions keep their reasons A decision without its rationale gets re-argued within 2 months; a recorded one does not. When you settle a decision, Atlas captures the outcome and the reasoning and writes it to decisions/NNNN-slug.md in your repository as an ordinary git-tracked ADR. The file is yours and readable without Atlas. Settling is idempotent, so a decision you confirmed never silently flips on a later pass. ## Settled decisions reach the agent, open ones do not Only settled decisions are injected into session context, and that 1 rule is a deliberate safety property. Atlas renders settled decisions into the system prompt so the agent works from what you already concluded. Open decisions stay out. That way an unresolved or wrongly captured question stays visible in your digest without silently steering every future session in the repository. ## Availability Decision Ledger is 1 of the 8 record engines in Atlas, and it sits behind the paid tier. The engine is built and running in the product, gated to Atlas Pro. Pro has no checkout yet, so it is not something you can buy today. Its live input is Intake, which reads call transcripts. Capturing decisions from coding sessions is built as a separate engine but is deliberately manual for now. Shipped, the automated work log, is the one record engine available free right now. ## FAQ ### Is Atlas decision tracking available now? The engine is built and running in Atlas, but it sits behind the paid tier and Atlas Pro is not yet on sale, so you cannot purchase access today. ### How is this different from a decision log? A log only records decisions you already made. The Decision Ledger also tracks open decisions you still need to make, ages them, and surfaces the oldest first. ### Where do the decisions come from? From the decisions Atlas Intake extracts from your call transcripts. Capturing decisions made during a coding session is built as a separate engine but is manual rather than automatic today. ### What happens when I settle a decision? Atlas writes an ADR to decisions/NNNN-slug.md in your repository with the outcome and rationale, flips the ledger entry to settled, and starts injecting it into session context. ### Do open decisions affect what the agent does? No. Only settled decisions are injected into context. An open or wrongly captured decision stays visible in your digest without steering the agent. --- Canonical HTML: https://runatlas.sh/resources/features/decision-tracking Source of truth: aeo_pages row `/resources/features/decision-tracking` (segment: Platform) (this file is generated from it, never hand-edited).
