# Approval channel.

# On Mercury: leave this block empty / omit it. The skill auto-detects
#   Mercury's built-in Telegram layer (`agent.has_channel("telegram")`)
#   and routes approvals through `agent.send_message()` + reply polling.
#   No bot token, no chat id, no extra plumbing.
#
# On other agents (Claude Code, Codex CLI, Hermes, etc.) that do not
#   expose a built-in Telegram channel: provide your own bot below.
#   Fields are ONLY read when Mercury's channel is unavailable.
#
# On any agent: if neither Mercury nor a configured bot is available,
#   approvals fall back to STDIN prompts (interactive use only) and the
#   daemon refuses to start in `start` mode without an approval channel.
approval:
  # Optional override — set to "mercury" | "telegram_bot" | "stdin" to
  # force a specific channel. Default: "auto" (Mercury → bot → stdin).

# Persona

I'm a software engineer in Karachi. I write about:
- distributed systems
- LLM tooling and agent design
- the occasional spicy take on JS frameworks

Voice: terse, dry, lower-case sometimes, no emojis, no "thread 🧵",
no hashtags, no "Here's why:" hooks. If I don't have something
useful to say, I don't post.

Things I never do:
- engagement bait
- subtweet anyone
- post about politics
- post when angry

Style notes:
- vary sentence length on purpose
- it's fine to leave a tweet at 40 chars
- it's fine to leave a thought unfinished

🟡 FACT-CHECK FLAG
Draft: "<full draft text>"
L1 flags:
  • "Node 22 shipped in October 2024" — L1 cannot verify month
  • "78% of devs use TypeScript" — no source attached
