Interactive Mode

Start meka without the -p flag to enter interactive mode:

meka

You get a prompt:

meka [r] >

Type your instruction and press Enter to submit. The agent processes your request and prints its response (streamed in real time as Markdown). When it finishes, you get another prompt.

Keybindings

meka uses Emacs-style keybindings (provided by reedline).

Input

Ctrl+DExit the shell (when the line is empty)
Ctrl+RReverse incremental search through history
Ctrl+LClear the screen

Input History

The prompts you type are saved to meka’s SQLite database, so Up / Down and Ctrl+R recall what you typed in any previous run. A brand-new meka, a resumed meka -c, and the current session all share one history. Multi-line prompts are preserved intact, and only the most recent entries are kept (older ones are pruned). This input history is separate from the conversation shown by /history.

Prompt Format

meka [indicator] >

The indicator shows the current permission mode:

ModeIndicatorColor
None[n]Green
Read[r]Yellow
Ask[a]Magenta
Write[w]Red

The color provides a visual cue about the agent’s current capabilities. Red means the agent can modify your system.

Multi-Line Input

Press Alt+Enter to insert a newline instead of submitting. The prompt changes to show continuation:

meka [r] > write a python script that
  ... prints hello world
  ... and saves it to hello.py

Press Enter on the last line to submit the entire multi-line input.

Pasting multi-line content also works seamlessly: all pasted lines appear in the buffer for review, and you press Enter to submit.

Slash Commands

meka supports / prefix commands for controlling the shell:

CommandDescription
/helpShow available commands
/exitExit the shell
/clearClear the terminal screen
/sessionShow the current session ID
/permission [none|read|ask|write]Show or set the permission level
/compactSummarize and compact the session history
/cd [path]Change working directory
/mcp listList configured MCP servers with their live state (pending / connected / failed / disabled)
/mcp reconnect <server>Smoke-test connect for one server
/mcp login <server>Run the OAuth flow from the REPL
/mcp logout <server>Revoke cached credentials for a server
/mcp <server>:<prompt> [args...]Render a server-defined prompt and send it to the agent
/statusShow session stats: live context-window usage, plus cumulative turns, tokens, cache hit ratio, redactions, message count
/usageShow the account’s rate-limit usage (subscription providers): session/weekly windows, percent used, reset times
/history [N]Reprint past conversation styled like the live REPL. Bare /history dumps everything; /history N shows the last N turns

Press Tab after typing / to open a completion menu of command names, each shown with its description; keep typing to narrow it (/comp + Tab completes to /compact). Tab also completes arguments: permission levels for /permission, installed skill names for /skill, the subcommands and configured servers for /mcp, and directory paths for /cd (Tab again after a completed directory drills into its subdirectories). The leading command token is colored as you type: an accent color when it names a known command, an error color when it does not.

/history

Replays prior messages in the current session so you can scroll back through context without exiting and re-resuming. /history with no argument dumps every materialised message; /history 5 shows the last 5 turns (a turn = the user’s prompt plus everything the agent did to respond). Any non-numeric argument (/history all, /history foo) falls back to the dump-everything path.

The renderer mimics the live REPL: assistant text flows through the same markdown highlighter, tool calls appear as [tool ReadFile(...)] indicators, and thinking blocks honour [thinking].show_content. User prompts are prefixed with a cyan > so they stand out from agent text.

For users who always want extra context at resume time, set display.resume_show_recent; the resume code path then renders the last N turns through the same function.

/status

Print a snapshot of the current session’s counters:

Session status
  Turns:           23
  Context:         128.4k / 1.0M (13% used, 871.6k left)
  Input tokens:    234.5k  (cache hit: 92%)
  Output tokens:   12.1k
  Redactions:      2 (12 images, ~38 MiB freed)
  Messages:        47

Context is the live context-window occupancy: the total tokens of the most recent exchange (all input tiers plus output, i.e. what the next request re-sends minus your new prompt), against the active model’s context window, with the percent used and tokens remaining. Use it to decide whether to /compact before continuing; after /compact it drops to the compacted size immediately. It reflects this session only; sub-agents spawned via spawn_agent have their own context and are not counted (a sub-agent’s returned result is counted only once it lands in this session as a tool result). The line is omitted until the first turn completes. Set display.show_context_in_prompt to show the same gauge in the prompt itself.

Input tokens (and the other cumulative counters) is the total billed across every turn of the whole session. These totals are persisted, so resuming a session with meka -c continues them rather than restarting at zero.

Redactions reports any times the Claude provider had to drop oldest tool-result image blocks because the request body would have exceeded Anthropic’s 32 MiB ceiling. A non-zero count indicates the cache prefix was invalidated for the redacted messages. See display.show_token_usage for a per-turn variant of the same data.

/usage

Fetch the account’s current rate-limit usage from the active provider and print each rolling window with its percentage used and reset time:

Account usage
  5-hour (session)   [#---------]   8% used  (resets in 4h 12m, 2026-07-02 02:10)
  Weekly             [----------]   2% used  (resets in 22h 50m, 2026-07-02 13:00)

This is distinct from /status, which reports this session’s own token counters. /usage queries the provider for your whole-account subscription limits. It works only for OAuth subscription providers that expose a usage endpoint (claude-oauth’s 5-hour and weekly windows; openai-codex’s primary/secondary windows plus plan and credit balance). For API-key backends, OpenAI-compatible endpoints, and Ollama, it prints a short “not available for this provider” note instead. The same command is available under ACP.

/compact

The /compact command asks the LLM to summarize the entire conversation, then replaces the messages the model sees with a single summary message followed by the recent tail. This is useful for long sessions that are approaching the context window limit or becoming expensive.

After compacting, the session continues with the summary as context. The pre-compaction messages are never deleted: they stay in the underlying event log on disk (the model just no longer sees them). meka session export walks that full log, so an export always contains the entire conversation including the compacted-away turns, with a marker at each compaction point.

Shell Escape

Prefix any input with ! to execute it directly as a shell command, bypassing the LLM entirely:

meka [r] > !pwd
/home/user/projects
meka [r] > !ls -la
total 32
drwxr-xr-x  5 user user 4096 Mar  4 10:00 .
...
meka [r] > !ping 1.1.1.1 -c 2
PING 1.1.1.1 (1.1.1.1) 56(84) bytes of data.
...

The command runs with inherited stdin/stdout/stderr, so it behaves exactly like a regular shell. This is useful for quick checks without waiting for the LLM.

Exiting

You can exit meka in any of these ways:

  • Type /exit
  • Type exit or quit
  • Press Ctrl+D on an empty line

Interrupting the Agent

Press Ctrl+C while the agent is running to interrupt it. This cancels the current LLM request and kills any running shell commands that were spawned by the agent.
