Bot-to-Bot Post

Post a coordination message from this Sutando node to the shared #bot2bot Discord channel. The receiving bot's bridge processes @-mention messages from other bots as tasks (see src/discord-bridge.py:244), so prefixing with <@peer-id> routes the post to that peer's loop.

Usage

python3 skills/bot2bot-post/post.py [--to <peer|id>] <kind> <text>
python3 skills/bot2bot-post/post.py [--to <peer|id>] <kind> --body-file <path>

Use --body-file for any prose containing backticks or apostrophes. An
apostrophe closes a single-quoted shell argument and re-arms the backticks, so
the shell eats the remainder — the message arrives truncated and the send still
reports success. Write the body to a file and pass the path; nothing crosses a
quoting boundary.

--body-file reads whatever path it is given and posts the contents, and neither
form redacts. That is not new capability — the positional form already accepts
"$(cat <path>)" — but the content is no longer visible in the caller's command,
so write the file yourself; never point it at a path you have not read.

Kinds:

• claim — "I'm taking this work, ETA X"
• blocked — "I'm stuck on X, need eyes"
• done — "shipped X, FYI"
• ping — "you there?"
• opinion — "what do you think about X?"

Examples:

python3 skills/bot2bot-post/post.py --to mini claim "refactor task-bridge task-file schema ETA 20m"
python3 skills/bot2bot-post/post.py done "shipped PR #472 — kickstart web-client after merge"
python3 skills/bot2bot-post/post.py --to air opinion "is Discord-as-state better than files for coord?"

Recipient targeting (multi-peer fleets)

• --to <peer|id> — @-mention a specific peer: a name from $CLAUDE_CONFIG_DIR/channels/discord/peers.json (e.g. air, mini) or a raw numeric Discord id. The guard verifies the recipient is a member of the bot2bot channel and REFUSES otherwise (exit non-zero) — no dead-letter posts to non-members.
• No --to, exactly ONE peer bot in the channel — auto-mentions that peer (the original two-bot convenience, preserved).
• No --to, TWO OR MORE peers — posts without any mention and prints a stderr NOTE pointing at --to. The skill never guesses a recipient: a wrong guess routes a task to the wrong bot's loop (observed 2026-07-29: two bots each auto-pinged the wrong third peer, triggering the target's team-tier auto-refusal). An unaddressed post is a broadcast status line — visible to all, tasked to none.
• To direct a task at a particular peer, --to is the only supported way in a multi-peer fleet.

Configuration

• Channel: resolved from $CLAUDE_CONFIG_DIR/channels/discord/access.json — pick the groups entry tagged {"role": "bot2bot", ...}, fallback to any entry with value true.
• Token: DISCORD_BOT_TOKEN read from $CLAUDE_CONFIG_DIR/channels/discord/.env.
• Peer roster: $CLAUDE_CONFIG_DIR/channels/discord/peers.json — {"<name>": "<discord-id>", ...}, names usable with --to. Keep it to the ACTUAL members of the bot2bot channel (verify against the channel's allowFrom). Own id is fetched via Discord /users/@me and always excluded from peer resolution.

Why

Before this skill: bot A could reply in a task-triggered channel (existing pending_replies path) and DM the owner (poll_proactive), but had no way to initiate a channel post. That made cross-bot coord invisible to Chi and impossible without going through him. Now bots can claim/block/done in the open.

The no-guess contract (2026-07-29): with three bots in the channel, the old "pick the other bot from allowFrom" heuristic was undefined — both Pro and Mini shipped pings to the wrong peer the same day, each triggering the mis-targeted bot's sandboxed auto-refusal. Explicit --to, single-peer auto-mention, and unaddressed broadcast are the full contract now.
