Generalizes the Telegram listener with a configurable text-prefix map
(telegram_prefixes.env): any non-command message '<word> <text>' runs
the mapped command with <text> appended as ONE quoted argument — e.g.
opencode=opencode turns 'opencode check cpu' into opencode "check cpu".
Routing order per message: text-prefix map → built-in Gemini ai bridge →
/command map → Unknown command. A mapped word shadows the Gemini bridge.
The prefix verb is reworked: bare = list map + bridge word; 'prefix
<word> <cmd...>' = map; 'prefix <word>' = show; 'prefix -r <word>' = remove.
The Gemini trigger word itself is now set via 'pos config telegram'
(TELEGRAM_AI_PREFIX).
Also extracted run_and_reply() to share the /command-map (60s) and
prefix (120s) execution semantics; fixed a latent set -e abort on
invalid templates in prefix_map_set's check_syntax call.
Verified: 27/27 routing-harness assertions, full CLI verb suite,
dispatch smoke, pos config telegram render, bash -n, make gen && make check,
make lint 0 FAIL / 0 WARN, shellcheck -S style (0 new findings).
Extract reply_to_message.text (fallback caption) from each getUpdates
result and pass it to handle_message; the ai bridge prefixes the prompt
with '[Reply context — the message you are replying to]', so replying to
a /status output and asking 'ai check this details' gives the model the
actual output. AI bridge only — mapped /commands unchanged; context rides
in the user turn so the session records what was analyzed. Docs:
howto/ai.md bridge section.
pos ai gemini: --session gives ask/chat persistent memory
(~/.local/share/linux_post_install/ai/<name>.json, capped 40 turns),
new 'sessions' subcommand to list/clear; --system injects a Gemini
systemInstruction on every turn without storing it in the session file.
Telegram listener keeps one session per chat (telegram-<chat_id>), clears
on 'ai /reset', passes a Telegram-voice system prompt (emojis welcome),
and strips markdown from replies before sendMessage since messages are
sent as plain text. Docs: howto/ai.md flags/sessions/bridge behavior.
- bin/pos-ai-gemini: one-shot ask (stdout-only, pipe-friendly), interactive
multi-turn chat REPL (q/Ctrl+C, /reset), models list; --model override,
default gemini-2.5-flash; key via x-goog-api-key header, never printed.
- Config scope 'ai' (AI_GEMINI_API_KEY secret, AI_GEMINI_MODEL) in
~/.config/linux_post_install/ai.env via 'pos config ai'; config/ai.env
template installed no-clobber by postinstall.
- Telegram listener: non-command text starting with 'ai ' (case-insensitive)
is answered by Gemini via 'pos ai gemini ask'; owner-chat only, errors
reply with the pos config ai hint. Future intents slot in as case arms.
- ai-gemini added to INTERACTIVE_CMDS (chat reads stdin).
- Docs: POS.md ai section + listener bridge, howto/ai.md, HOWTO/README
index rows, bin/pos usage example; make gen refreshed context/completions.
