Commands:
cctop <agent> [args…] Start claude, codex, opencode or pi on a pty cctop
owns, so the UI can watch it and type into it. Same
as `cctop run <agent>`; the args go to the agent.
cctop attach [pid] Put a running agent on this terminal — no pid lists
them. F12 detaches and leaves it running.
cctop as <acct> <agent> Start an agent under a named account (see
--add-account).
cctop sandbox <host>:<path> [args…]
Run Claude Code here with its Bash commands on
<host> over ssh, and <path> mounted here with sshfs.
cctop serve Serve the table, and a per-session report, to a
browser. Loopback and read-only by default; `serve
--help` for the flags. Handy on a phone.
cctop wait <session> Block until a session stops working — by id prefix,
tab name or pid. For one agent to wait on another.
cctop doctor Check this installation and say what is wrong with
it: sessions, pricing, hooks, and what `s` reaches.
--host also tests an ssh target.
cctop why [session] Why a row says a session is running, or is not:
every agent process, its session, the rule that
matched it.
cctop optimize What your sessions spent and did not get back.
Reads only.
cctop compare How each model did on the work you actually gave
it — one-shot rate, cost per file, cache hit.
cctop yield Whether what each session spent ended up in a
commit on the default branch. Reads only.
cctop recall <query> What past sessions, from any agent, said about
something — the passages, ranked. Agents get it
through --mcp; --install-mcp sets that up.
cctop burn What your subscription windows were paid for and
did not use.
cctop log Print the event stream CCTOP_LOG writes; -f follows
it.
cctop --trace Time each stage of a run, for a bug report about
slowness.
Each command takes --help for the details.";

long_about = "cctop — an htop-like monitor for AI coding agent sessions\n\n\
Tracks Claude Code, Codex, Cursor, Devin, Gemini CLI, OpenCode, Pi, and\n Windsurf\n\
sessions on your machine, showing real-time cost estimation, token usage, tool\n\
invocations, and OS-level metrics.\n\n\
COST ESTIMATION\n \
Cost figures are estimates based on per-token API pricing from the LiteLLM\n \
database (cached locally for 24 hours). Many subscription plans — such as\n \
Claude Max, Pro, or Team — charge a flat rate or bundle tokens differently,\n \
so reported costs may not reflect your actual bill. Treat the $ column as a\n \
rough indicator of resource consumption, not as an authoritative invoice.\n\n\
LAUNCHING AGENTS\n \
`cctop <command> [args…]`, or `cctop run <command>`, starts the agent on a pty\n \
cctop owns so the UI can type into it with `s`. Everything after the command,\n \
flags included, goes to the agent. The first interactive run aliases the known\n \
agents to this form in your shell startup files; --remove-alias undoes that.\n\n\
ATTACHING\n \
Agents started that way can be watched and driven from anywhere. Press `a` in\n \
the UI, or run `cctop attach [pid]` to put one on the terminal directly —\n \
with no pid it lists what is running. F12 detaches and leaves it running. The\n \
agent is resized to the smallest window watching it, and gets its size back\n \
when that one detaches.\n\n\
RESUMING\n \
`R` in the UI reopens any session in a tab of its own, by running its own\n \
harness's resume command in the directory it was working in. Unlike `a` this\n \
needs nothing of cctop at the time the session ran, so it reaches the sessions\n \
started from anywhere — including ones that ended long ago.\n\n\
IN A BROWSER\n \
`cctop serve` puts the same table on an HTTP port, streaming it over SSE, plus\n \
a page per session: the conversation, what it edited, what it can reach, and\n \
where its money went. From there it can send a prompt to a live session,\n \
resume a dead one, or hand one to a different agent. It listens on 127.0.0.1\n \
with a per-run access token in the URL, which is the whole credential — so\n \
whoever holds the link can drive these agents. `--bind` is what puts it on the\n \
network and `--tunnel` puts it on the internet, both saying so when they do;\n \
`--no-actions` serves the pages without the buttons.\n\n\
SEARCHING\n \
`/` filters on what the table shows plus the full working directory and the\n \
branch; `Tab` in that prompt extends the search into the transcripts, which\n \
reads them off disk and so is opt-in.\n\n\
DIAGNOSING\n \
`cctop doctor` reports where sessions are read from and how many it found,\n \
whether pricing loaded, which agent hooks are installed, and what `s` can\n \
reach. It exits non-zero only for a real fault, so it is usable in a script.\n \
`cctop doctor --host <host>` additionally makes the ssh round trip.\n \
--trace answers the other question, which is why a run is slow. It times each\n \
stage — discovery, transcript parsing, the cache, the pricing fetch — and\n \
writes the totals to a file when cctop exits, for attaching to a bug report.\n \
It carries counts and durations only: no session titles, project paths or\n \
file names, and cctop's own paths are spelled with `~`.\n\n\
EVERY USER\n \
Run as root and cctop reads every user's sessions rather than root's own,\n \
naming whose each row is in the USER column; `/user:<name>` filters to one.\n \
Other homes are only read: cctop writes nothing into them, and refuses to\n \
delete another user's session. CCTOP_ALL_USERS=0 turns that\n \
off, =1 turns it on without root, and CCTOP_HOMES names homes that are\n \
neither in /etc/passwd nor under /home.\n\n\
NOTES\n \
Session data is read from each agent's standard local session store.\n \
UI preferences (active tab, sort order, filters) persist across runs.",
