+# Memory Update — decompose-agent — 2026-02-21
+
+## Key findings
+- Extracted `cmdCheck`, `cmdList`, `cmdComplete` from `src/lib.mjs` into separate files.
+- `scripts/check-file-size.mjs` does not have a `BASELINE` object to update, effectively a read-only report tool.
+
+## Patterns / reusable knowledge
+- When decomposing `src/lib.mjs`, ensure dependencies (imports) are correctly moved or re-imported.
+- `COMMAND_HANDLERS` in `src/lib.mjs` makes it easy to swap implementations.
+
+## Warnings / gotchas
+- `scripts/check-file-size.mjs` --update flag does not update the file itself.

+- Run-Start: 2026-02-21T22-21-27Z
+- Prompt: src/prompts/daily/decompose-agent.md
+
+## Goal
+Decompose `src/lib.mjs` into smaller modules to reduce size by at least 200 lines.
+
+## Scope
+Decomposition of `src/lib.mjs` by extracting command implementations.
+
+## Constraints
+- Do not change behavior.
+- Reduce size by at least 200 lines.
+- Preserve existing functionality.
+
+## Selection
+- File: `src/lib.mjs`
+- Original Size: 730 lines
+- Reason: Largest grandfathered file not recently refactored (based on manual check).
+- Commit SHA: a6c06ce173fbbff9170476e4b97c1bac4b30cb10
+- Node/npm: v22.22.0 / 11.7.0
+
+## Plan
+Extract cohesive blocks:
+1. `cmdCheck`
+2. `cmdList`
+3. `cmdComplete`

+- Session: 2026-02-21T22-21-27Z
+- Run-Start: 2026-02-21T22-21-27Z
+- Prompt: src/prompts/daily/decompose-agent.md
+
+## Decision
+Extract `cmdCheck`, `cmdList`, and `cmdComplete` into separate modules.
+
+## Rationale
+These are distinct, cohesive command implementations that can be cleanly separated from the main entry point to reduce file size and improve maintainability. `src/lib.mjs` was over 700 lines.
+
+## Naming
+- `src/cmd-check.mjs`: Specific to check command.
+- `src/cmd-list.mjs`: Specific to list command.
+- `src/cmd-complete.mjs`: Specific to complete command.
+
+## Baseline Update
+- Reduced `src/lib.mjs` from 730 lines to 438 lines (292 lines reduced).
+- `scripts/check-file-size.mjs` does not support programmatic baseline updates or contain a `BASELINE` object, so manual update of the script was not possible/needed.
