getstream Ralph Protocol (Agent Collaboration)
Files are the source of truth. All agents share memory via files. No silent decisions. Always update state after acting. Prefer small, explicit updates.
Required Files
Location: Generate and keep spec files in a dedicated folder inside the specs folder at the root of the repo: specs/<feature-or-component-name>/. Example: specs/resizable-container/goal.md, specs/resizable-container/plan.md, specs/resizable-container/state.json, specs/resizable-container/decisions.md. One folder per feature or component; do not put spec files next to source (e.g. not under src/components/...).
| File | Purpose |
|---|---|
| spec.md or goal.md | What we achieve; success criteria; constraints; non-goals. Read first. Only change if goal actually changes. No implementation details. |
| plan.md | How we achieve it. Ordered tasks, ownership, dependencies, status (pending | in-progress | done | blocked). Propose changes before big deviations; don't rewrite completed sections. |
| state.json | Current memory. Task statuses, flags (blocked, needs-review, etc.). Update immediately after acting. Read before assuming anything. |
| decisions.md | Log of non-trivial decisions (what + why). Append only; never delete. Prevents reopening or contradicting past choices. |
Workflow
Before acting: Read the spec files in specs/<name>/: spec.md (or goal.md) → plan.md → state.json → decisions.md.
During: Follow the plan; no overlapping work unless coordinated; no undocumented decisions.
After: Update specs/<name>/state.json → record decisions in specs/<name>/decisions.md → update task status in specs/<name>/plan.md. Optionally add learnings to observations.md in the same folder.
Prohibited: Decisions without recording; using chat as memory; re-solving done problems; changing goals implicitly; overwriting files without explanation.
Task ownership (critical)
- Work on exactly one task at a time.
- That task must be in the plan file (
specs/<name>/plan.md), markedin-progressand assigned to you. - Do not change files for other tasks, even if small.
Commit scope
Only commit files that were changed for the current task. Use git add <file> — never git add -A or git add .. Leave unrelated changes unstaged.
UI E2E
When acceptance criteria involve UI: use Playwright (MCP or project config). Take screenshots for success and failure. Save to a clear location (e.g. __tests__/screenshots/).
Loop reminder
Each iteration: Plan (update specs/<name>/plan.md if needed) → Act (scoped work) → Reflect (learnings) → Refine (plan or decisions).
For decision log format and state.json example, see reference.md. Plan structure and worktrees: use make-plans and worktrees skills.
