Strato

strato — the agent OS skill

strato's model is the per-turn loop (STRATO.md). This skill is the executable for the loop's slower clock — the per-heartbeat work that makes a workspace compound: set the workspace up, audit it on a cadence, and turn what was learned into durable improvement. Read [../../../STRATO.md](../../../STRATO.md) for the model.

It never re-embeds file contents: the workspace's starter files live in strato's [templates/](../../../templates/) directory and are the single source of truth. Module index.md files are routers, not second copies of the module detail.

Three modes — pick by the workspace state and the request.

bootstrap — first time in a workspace

Use when SOUL.md / USER.md / AGENTS.md / MEMORY.md / STATE.md are missing at the workspace root, or the user says "set up the workspace".

Procedure: explore → interview → confirm → write, laying down the templates/ populated with the user's answers. The interview uses the loop's opener (I think I know / I am inferring / I do not know / please confirm) at the chosen depth (3 / 5 / 8 / 10 questions). Full steps in [references/bootstrap.md](references/bootstrap.md).

heartbeat — periodic audit

Use on a schedule or when the user says "run a heartbeat" / "audit the workspace". Two flavors: light (read-only findings report) and deep (interactive cleanup, per-item prompts). Surfaces stale folders, cross-project bleed, skill candidates, dead skills, automation drift, and playbook gaps. Checklist + report format in [references/heartbeat.md](references/heartbeat.md).

self-improve — capture, extract, package

Use after a slice, a bug, or a confusing handoff, or when the user says "this happened again" / "package this into a skill". Three procedures — the bug-risk playbook, the third-strike skill rule, and workflow-plugin packaging — in [references/self-improvement.md](references/self-improvement.md).

🚦 Gates (mirror STRATO.md — never batch)

• Never delete or move a file without showing paths and getting per-item

confirmation (require the user to type the name for a delete).

• Never modify SOUL.md / USER.md / AGENTS.md after bootstrap, or change an

existing skill, without approval.

• Never publish, push, or send externally without explicit per-item approval.
• Creating a new SOP/skill/plugin: show the draft first.

Done means

• The workspace has a discoverable shared brain (the templates/ files, populated)

that survives a session restart.

• The latest heartbeat report is within the configured cadence.
• Lessons from the last session landed in bug-risk-playbook.md or a skill — not just

in chat.

• Any third-strike workflow this session became a skill, a plugin, or an explicit "no".
