-# Agent Instructions
-
-This documentation workspace uses Taskmaster as the source of truth for agent work.
-
-## Repository Rules
-
-- Repository-wide operating rules live in `RTK.md` at this vault root; follow them in addition to this file.
-- For product or code changes that affect frontend or backend, keep `frontend` and `backend` package versions/build numbers bumped together and synchronized unless the user explicitly asks otherwise.
-- Preserve Telegram Mini App auth retry behavior: `/api/auth/telegram` must accept repeated valid `initData` for the same launch session; replay rejection belongs only on one-time routes such as webhook/session creation.
-- In the final response, mention version/build bumps and verification commands when they were part of the work.
-
-## Sync-From-Code Rule (MANDATORY)
-
-Whenever an agent finishes a commit-push in `../backend` or `../frontend`, this
-vault MUST be updated **in the same working session**:
-
-1. Add a new entry to `09 - Audits/Activity Log.md` — newest at the top.
-   Use this template:
-
-   ```markdown
-   ### YYYY-MM-DD — <repo>@<short-sha> — <one-line summary>
-
-   **Commits:** `<sha1>` `<sha2>` …
-   **Touched:** path/one.ts, path/two.tsx
-   **Why:** <motivation — bug, feature, PRD link, incident #>
-   **Verification:** <build status, smoke result, manual check>
-   **Linked docs updated:** [[03 - API Reference/Foo]], [[04 - Flows/Bar]]
-   ```
-
-2. If the change affects API surface, data models, flows, architecture, ops,
-   env vars, or design, update the matching numbered section in this vault
-   in addition to the Activity Log entry (do not just log it).
-
-3. Commit with message: `docs: sync from <repo> <short-sha> — <summary>` and
-   push to `origin/main`.
-
-The companion `AGENTS.md` files at `../backend/AGENTS.md` and
-`../frontend/AGENTS.md` carry the same rule from the code-side.
-
-## Taskmaster Workflow
-
-- Before choosing implementation or documentation work, run `task-master next` from the repository root.
-- Inspect the selected task before editing with `task-master show <id>`.
-- When starting a task or subtask, mark it active:
-  - `task-master set-status --id=<id> --status=in-progress`
-- Keep Taskmaster updated as work progresses:
-  - `task-master update-subtask --id=<id> --prompt="<what changed, what was learned, blockers, and verification>"`
-- When work is complete and verified, mark it done:
-  - `task-master set-status --id=<id> --status=done`
-- If work is paused or incomplete, leave the task in `in-progress` and add a progress note with the remaining work.
-
-## Local Task Files
-
-- Canonical Taskmaster data: `.taskmaster/tasks/tasks.json`
-- Per-task markdown files: `.taskmaster/tasks/task-*.md`
-- Source PRDs and audits: `.taskmaster/docs/*.md`
-- Public share copy: `taskmaster-share/tasks.json`
-
-Do not hand-edit `.taskmaster/tasks/tasks.json` or generated task markdown files unless the user explicitly asks for direct file maintenance. Prefer Taskmaster CLI commands so task state stays consistent.
-
-## Expected Agent Behavior
-
-- Treat pending Taskmaster tasks as the prioritized backlog.
-- Respect task dependencies shown by `task-master next` and `task-master show`.
-- Update the relevant task whenever edits, findings, verification results, or blockers materially change the state of the work.
-- Before the final response, confirm that Taskmaster reflects the current task status AND that the Activity Log has the latest push entry (if a push happened in this session).
-- If `task-master` is unavailable, mention that in the final response and summarize the Taskmaster update that should be applied manually.
