Record an architectural decision, a resolved bug's root cause, a coding standard, or a system configuration as a structured note in the vault. Use when the user says "remember this," "save this to the vault," "document this decision," or /decision-log.

Log a vault change (note created/edited/deleted) to a running daily changelog note. After any write to the vault, ask the user "should this be logged?" and run this skill on confirmation. Also runs directly when the user says /changelog.
Update a project's README and the relevant vault notes (overview / module map) after a meaningful code change — new feature, new file, new module, or an architectural decision. Should trigger on its own once a coding task is finished, without the user having to ask — skip it for trivial (typo/formatting) changes. Also runs manually when the user says "update the docs" or "document this."
Update "where we left off" tracking for {PROJECT} when a milestone or unit of work closes. Updates Status.md (active milestone + next concrete action) and Milestone_Log.md (chronological record); touches Goal.md/Decisions.md if needed. Called by project-orchestrator at the end of every milestone; also used directly when the user says "log this milestone" or "update status."
Design phase for {PROJECT} — data model, module boundaries, API contract, access control, and any multi-tenancy/security design, before code is written. Called by project-orchestrator before implementation; also used directly when the user says "design {PROJECT}'s X module."
Implementation phase for {PROJECT} — builds the actual code for a module or vertical slice against an existing design. Called by project-orchestrator once a design exists; also used directly when the user says "implement {PROJECT}'s X module."
Main orchestrator for building {PROJECT}. Tracks cross-session continuity, reads "where we left off," routes to the correct phase sub-skill, and runs autonomously. Use when the user says "continue {PROJECT}," "work on {PROJECT}," "{PROJECT} where did we leave off," or /project-orchestrator. This is for the BUILD side of {PROJECT} — not for unrelated day-to-day tasks about it.

Not everything worth remembering belongs in Claude's cross-session memory — memory is for small, personal working-style facts. Anything with enough substance to be useful to a future reader of the project, not just future-Claude, belongs in the vault instead.
