+# Agent Instructions
+
+## Scheduled Reminders
+
+**Personal reminders for the user** (notifications about tasks they need to do) → use the `/remind` skill → stored in `reminder.yaml`. Never use the `cron` tool for these.
+
+**Background agent tasks** (run a script, check something, autonomous action) → use the built-in `cron` tool directly.
+
+Test: *Who is the recipient?* User gets notified → `reminder.yaml` via `/remind` skill. Agent executes something → `cron` tool.
+
+**Do NOT just write reminders to MEMORY.md** — that won't trigger actual notifications.
+
+## Heartbeat Tasks
+
+`HEARTBEAT.md` is checked on the configured heartbeat interval. Use file tools to manage periodic tasks:
+
+- **Add**: `edit_file` to append new tasks
+- **Remove**: `edit_file` to delete completed tasks
+- **Rewrite**: `write_file` to replace all tasks
+
+When the user asks for a recurring/periodic task, update `HEARTBEAT.md` instead of creating a one-time cron reminder.
+
+## Databases (SQLite)
+
+Always store SQLite databases under `db/*.sqlite` (relative to the workspace root).
+Never use `/tmp/`, hardcoded absolute paths, or in-memory databases for persistent data.
+
+## How you were extended & tuned
+
+`develop/` records how this instance was extended and tuned — skills, config, service work — with verified facts and a change log you can learn from (not the upstream code). See `develop/README.md`; read on demand.
+
+## Knowledge base
+
+`knowledge/` holds verified facts and measured values you can draw on when answering (e.g. notes on the models available to you). See `knowledge/README.md` for what's there; read on demand.

+# Tool Usage Notes
+
+Tool signatures are provided automatically via function calling.
+This file documents non-obvious constraints and usage patterns.
+
+## exec — Safety Limits
+
+- Commands have a configurable timeout (default 60s)
+- Dangerous commands are blocked (rm -rf, format, dd, shutdown, etc.)
+- Output is truncated at 10,000 characters
+- `restrictToWorkspace` config can limit file access to the workspace
+
+## grep — Content Search
+
+- Use `grep` to search file contents inside the workspace
+- Default behavior returns only matching file paths (`output_mode="files_with_matches"`)
+- Supports optional `glob` filtering (e.g. `glob="*.py"`) plus `context_before` / `context_after`
+- Supports `type="py"`, `type="ts"`, `type="md"` and similar shorthand filters
+- Use `fixed_strings=true` for literal keywords containing regex characters
+- Use `output_mode="files_with_matches"` to get only matching file paths
+- Use `output_mode="count"` to size a search before reading full matches
+- Use `head_limit` and `offset` to page across results
+- Prefer this over `exec` for code and history searches
+- Binary or oversized files may be skipped to keep results readable
+
+## cron — Background Agent Tasks
+
+- Use `cron` only for **background agent tasks** (scripts, checks, autonomous actions).
+- For **personal reminders to the user**, use the `/remind` skill instead (`reminder.yaml`).
+- Do not call `nanobot cron` via `exec` — use the built-in `cron` tool.
+
+## python — use uv
+
+For all Python code (scripts, snippets, one-liners, tools) use `uv`,
+not `python` / `python3` / `pip` directly.
+
+- Run a script: `uv run script.py` (not `python script.py`)
+- One-liner / snippet: `uv run --with <pkg> python -c '...'`
+- Script with declared dependencies: `uv run --script script.py`
+  (PEP 723 header inside the file)
+- Add a project dependency: `uv add <pkg>` (not `pip install`)
+- Remove: `uv remove <pkg>`
+- Sync environment: `uv sync`
+- Run a tool: `uv run pytest`, `uv run ruff`, `uv run mypy`, …
+- REPL: `uv run python`
+
+Do not use `pip`, `pip-tools`, `poetry`, `conda`, or the system `python`.
+Reason: isolated, reproducible environments with no system-level side
+effects, faster resolves, no "works on my machine" surprises.
+
+## log/reminder.log — doručené připomínky
+
+Odeslané připomínky se logují do `log/reminder.log` (append-only, formát
+`YYYY-MM-DDTHH:MM:SS <text>`, Prague time, bez timezone suffixu). Posílá je
+**systémový cron uživatele nanobot** (`skills/remind/scripts/remind_send.py`)
+přímo přes Telegram, mimo agenta. Když se uživatel ptá na minulé/dnešní
+připomínky („připomněl jsi mi…?", „co dnes přišlo?"), přečti tento soubor.
+Vedle něj v `log/reminder_cron.log` se zachytává stdout/stderr crontabu —
+za normálního běhu prázdný, plní se jen při pádech skriptu.

+# Plán: /todo skill a unifikace /note, /remind, /keep
+
+## Cíl
+Prozkoumat všechny možné architektonické přístupy k vytvoření `/todo` skillu a případné unifikaci s existujícími skilly `/note`, `/remind`, `/keep`. Žádná implementace dokud plán není schválen.
+
+## Fáze 1: Brainstorming alternativních přístupů
+
+### 1.1 Event-sourcing / append-only log
+- Místo CRUD v SQLite: každá akce je immutable event (`TaskCreated`, `TaskCompleted`, `TaskDeleted`)
+- Aktuální stav se materializuje z event logu
+- Výhody: audit trail, undo/redo, distribuovaná synchronizace
+- Nevýhody: komplexita, overkill pro osobní asistenta
+
+### 1.2 File-based s Git history
+- Každý úkol = jeden markdown file v `tasks/` directory
+- Git commit = historie změn
+- Výhody: lidsky čitelné, diff-friendly, Git jako audit trail
+- Nevýhody: pomalé listování, race conditions při paralelním zápisu, složité vyhledávání
+
+### 1.3 SQLite + JSONB flex schema
+- Jedna tabulka `items` s `data JSONB` sloupcem
+- Každý typ (note, todo, reminder, keep) má vlastní schema uvnitř JSON
+- Výhody: extrémní flexibilita, žádné ALTER TABLE migrace
+- Nevýhody: ztráta typové bezpečnosti, složité dotazy, SQLite JSONB je relativně nové
+
+### 1.4 Graph-based (RDF / knowledge graph)
+- Úkoly a poznámky jako uzly v grafu, vztahy jako hrany
+- "úkol X souvisí s poznámkou Y", "úkol Z závisí na úkolu W"
+- Výhody: bohaté vztahy mezi entitami
+- Nevýhody: obrovská komplexita, žádný jednoduchý CLI
+
+### 1.5 Hybrid: SQLite + Markdown export
+- Primární storage SQLite (rychlé dotazy, fulltext search)
+- Periodický export do markdown (čitelnost, Git backup)
+- Výhody: kombinuje výhody obou světů
+- Nevýhody: duplicitní data, synchronizační problém
+
+### 1.6 Plugin architektura
+- Jeden core skill `/item` s rozhraním
+- `/note`, `/todo`, `/remind`, `/keep` jako pluginy registrující se do core
+- Výhody: extensibility, čisté separation of concerns
+- Nevýhody: potřebuje plugin API v nanobot frameworku (neexistuje)
+
+### 1.7 CLI-first s TUI
+- Místo chat-based: terminal UI (např. `taskwarrior`, `todo.txt`)
+- Nanobot jen wrapper volající externí CLI
+- Výhody: battle-tested tools, offline použití
+- Nevýhody: závislost na externím toolu, méně integrace s LLM
+
+## Fáze 2: Hlubší analýza 3 nejslibnějších variant
+
+Z fáze 1 vybrat 3 varianty pro detailní pro/contra:
+- Varianta C z předchozí analýzy (konvergence / thin wrapper)
+- Varianta 1.3 (SQLite + JSONB flex schema)
+- Varianta 1.5 (hybrid SQLite + Markdown)
+
+Pro každou variantu:
+- Datový model (ER diagram / schema)
+- Příkazová struktura (všechny subcommands)
+- Migrace z existujících skillů
+- Testovací strategie
+- Maintenance overhead
+- User experience flow
+
+## Fáze 3: Rozhodovací kritéria a scoring
+
+Definovat vážená kritéria:
+- Jednoduchost implementace (30%)
+- Jednoduchost použití (25%)
+- Extensibility (15%)
+- Data integrity / reliability (15%)
+- Performance (10%)
+- Aesthetics / "feels right" (5%)
+
+Každá varianta dostane skóre 1-5 v každém kritériu.
+
+## Fáze 4: Finální doporučení
+
+Na základě scoringu vybrat vítěznou variantu.
+Popis: proč právě tato, co se stane s existujícími skilly, roadmap implementace.
+
+## Omezení
+- Žádná implementace dokud plán není explicitně schválen
+- Analýza musí být kompletní — žádné "to se vyřeší později"
+- Každá varianta musí mít konkrétní pro/contra, ne obecné fráze
