fix(telegram): v0.0.7 reliability rollup — state-dir, PID guard, ppid watchdog, install stdout (#1424) 
* fix(telegram): honor TELEGRAM_STATE_DIR/CLAUDE_CONFIG_DIR in skills and server

The server already reads TELEGRAM_STATE_DIR for multi-bot setups, but the
/telegram:access and /telegram:configure skills hardcoded
~/.claude/channels/telegram/ in 11 places. So with a custom state dir the
skill writes access.json to the default location while the server reads
from the override — pairing and allowlist edits silently don't take effect.

Skills now resolve the state dir via shell expansion (TELEGRAM_STATE_DIR →
CLAUDE_CONFIG_DIR/channels/telegram → ~/.claude/channels/telegram) before
any read/write. Server gets the same CLAUDE_CONFIG_DIR fallback. Also adds
Bash(echo)/Bash(chmod) to configure skill's allowed-tools (chmod was already
documented but not allowlisted).

* fix(telegram): verify stale PID is a server.ts process before SIGTERM

PID files race with OS PID recycling. The lockfile from #1349 stored only a
PID; after enough churn that PID can be reassigned to anything — including
the new launch's own bun-run wrapper. SIGTERMing the wrapper closes our
stdin and triggers immediate self-shutdown ('replacing stale poller' then
'shutting down' within seconds — matches #1459 item 3).

Now check 'ps -p <pid> -o args=' contains 'server.ts' before killing.
execFileSync (no shell); whole block already try/catch so Windows/ps-missing
falls through to just overwriting the lockfile.

* fix(telegram): drop ppid watchdog check; redirect bun install stdout to stderr

Two v0.0.5/0.0.6 regressions causing the plugin to fail at startup:

1. The orphan watchdog's process.ppid !== bootPpid check false-fires when the
   bun-run/shell wrapper exits or execs during normal startup and we get
   reparented to init — plugin self-terminates ~5s after launch. Stdin-close
   alone is the correct signal: the kernel closes the MCP pipe on any CLI
   death regardless of intermediate wrappers, so the ppid check was both
   unnecessary and harmful. (#1467; also the actual cause of #1459 item 3
   and likely #1425.)

2. 'bun install --no-summary' in the start script writes to stdout, which is
   the MCP JSON-RPC transport. The harness sees non-JSON bytes during the
   handshake and drops the connection ('Failed to connect'). Redirect install
   output to stderr. (#1470; also explains #1425 on Windows.)

/telegram:configure — Telegram Channel Setup

Writes the bot token to <state-dir>/.env and orients the user on access policy. The server reads both files at boot.

Resolve the state directory first (it may be overridden for multi-bot or per-project setups):

echo "${TELEGRAM_STATE_DIR:-${CLAUDE_CONFIG_DIR:-$HOME/.claude}/channels/telegram}"

Use the printed path everywhere below in place of <state-dir>. The default is ~/.claude/channels/telegram.

Arguments passed: $ARGUMENTS

Dispatch on arguments

No args — status and guidance

Read both state files and give the user a complete picture:

  1. Token — check <state-dir>/.env for TELEGRAM_BOT_TOKEN. Show set/not-set; if set, show first 10 chars masked (123456789:...).

  2. Access — read <state-dir>/access.json (missing file = defaults: dmPolicy: "pairing", empty allowlist). Show:

    • DM policy and what it means in one line
    • Allowed senders: count, and list display names or IDs
    • Pending pairings: count, with codes and display names if any

  3. What next — end with a concrete next step based on state:

    • No token → "Run /telegram:configure <token> with the token from BotFather."
    • Token set, policy is pairing, nobody allowed → "DM your bot on Telegram. It replies with a code; approve with /telegram:access pair <code>."
    • Token set, someone allowed → "Ready. DM your bot to reach the assistant."

Push toward lockdown — always. The goal for every setup is allowlist with a defined list. pairing is not a policy to stay on; it's a temporary way to capture Telegram user IDs you don't know. Once the IDs are in, pairing has done its job and should be turned off.

Drive the conversation this way:

  1. Read the allowlist. Tell the user who's in it.
  2. Ask: "Is that everyone who should reach you through this bot?"
  3. If yes and policy is still pairing → "Good. Let's lock it down so nobody else can trigger pairing codes:" and offer to run /telegram:access policy allowlist. Do this proactively — don't wait to be asked.
  4. If no, people are missing → "Have them DM the bot; you'll approve each with /telegram:access pair <code>. Run this skill again once everyone's in and we'll lock it."
  5. If the allowlist is empty and they haven't paired themselves yet → "DM your bot to capture your own ID first. Then we'll add anyone else and lock it down."
  6. If policy is already allowlist → confirm this is the locked state. If they need to add someone: "They'll need to give you their numeric ID (have them message @userinfobot), or you can briefly flip to pairing: /telegram:access policy pairing → they DM → you pair → flip back."

Never frame pairing as the correct long-term choice. Don't skip the lockdown offer.

<token> — save it

  1. Treat $ARGUMENTS as the token (trim whitespace). BotFather tokens look like 123456789:AAH... — numeric prefix, colon, long string.
  2. mkdir -p the resolved <state-dir>.
  3. Read existing .env if present; update/add the TELEGRAM_BOT_TOKEN= line, preserve other keys. Write back, no quotes around the value.
  4. chmod 600 on <state-dir>/.env — the token is a credential.
  5. Confirm, then show the no-args status so the user sees where they stand.

clear — remove the token

Delete the TELEGRAM_BOT_TOKEN= line (or the file if that's the only line).

Implementation notes

  • The channels dir might not exist if the server hasn't run yet. Missing file = not configured, not an error.
  • The server reads .env once at boot. Token changes need a session restart or /reload-plugins. Say so after saving.
  • access.json is re-read on every inbound message — policy changes via /telegram:access take effect immediately, no restart.
