Guards

KOZMOS Skies: the session's weather above the prompt. Tool failures, context and rate-limit pressure, stalls and the local hour make clear skies, clouds, rain, storms with lightning, fog, a starry night, or a rainbow after a storm clears; an animated scene and a forecast line. /skies toggles it.

KOZMOS Stamp: a receipt on every finished turn. The closing 'Baked for 42s' line becomes a compact row of duration, tool calls by family as colored chips, tokens in and out, the turn's cost and the context fill with its change. /stamp toggles it.

KOZMOS Storyboard: Claude narrates its own progress. A chapter tool the model calls at each phase change drives a band above the prompt: the chapter title, a five-stage rail (explore, plan, build, verify, ship) with the active stage glowing, step 3/5 and a note. /storyboard toggles the band, /storyboard log opens the chapter history.

KOZMOS Switchboard: an MCP observatory sidebar. Every MCP server in the session with its tools, calls, errors, average and p95 latency, last call and a status lamp (healthy, erroring, idle, busy); servers with no calls yet too, and per-tool rows on expand. On the desktop a patch bay with glowing cables to the active servers. /switchboard toggles it.

KOZMOS Taskforge: a live kanban of the session's tasks. TodoWrite lists and TaskCreate/TaskUpdate tasks fall into Pending, In progress and Done columns with the active form, time in the column and the owning agent, under a progress bar. /taskforge toggles the sidebar.

KOZMOS Terminus: the session's shell history in a sidebar. Every Bash and PowerShell call of the main loop and its subagents with command, description, cwd, exit status, duration, output size and who ran it; filters for failed and slow runs, copy and re-run buttons. /terminus toggles it.

KOZMOS Throttle: a car dashboard above the prompt. Speedometer of output tokens per second, fuel gauge of the 5-hour limit, temperature of the context, an odometer of session dollars, and check-engine, fuel and overheat lamps. /throttle toggles it.

KOZMOS Tidewater: the live diff of the current turn as tides above the prompt. Every file Claude edits gets its own pool of rolling waves, a green swell for added lines and a red ebb for removed ones, with file chips and totals like '+128 −42 · 6 files'. From the first edit of a turn until the next prompt. /tidewater toggles it.

KOZMOS Vitals: a btop-style machine monitor sidebar. CPU with a braille history graph, RAM bar and history, disk use, NVIDIA GPU load, memory and temperature, process count, and the Claude side: session time, tool calls, running agents. Samples every 2 s only while open. /vitals toggles it.

TypeSafe's Jev decides how Claude Code works on each prompt: the main conversation's reasoning effort (low to xhigh, raised to max mid-turn when tool calls keep failing), each subagent's model, whether to split the work across subagents, and the one skill the prompt needs. Brings in custom OpenRouter models (a junior coder reviewed by Opus, or cheap bulk work) and Codex or OpenCode as...

Shrinks each Bash result before the model reads it: per-command filters for git, test runners, linters, package managers, containers and file tools, the full output kept in a file.

Runs proof-driven bug hunt rounds with /bughunt: each round proves one bug with a failing command the mod runs itself, fixes it, and proves the fix, and the loop stops on a blocked or unverified round. /bughunt collab runs a read-only scanner, planner and critic in sequence.

Parses each JSON, YAML, TOML or .env file an Edit or Write touches, notes a parse error at once instead of at the next build, and says so again when a later edit fixes it.

Checks each package the model installs against its registry and OSV.dev, and stops a missing, brand-new, look-alike, outdated or vulnerable one, naming the latest version.

Adds a note to the fifth edit of one file in one turn, so the model re-reads the code path and states the root cause instead of trying again.

After each commit the model makes, names the env variables its added lines read that .env.example lacks, with the file and line of each.

After an edit that calls translation keys, names the keys the JSON, Laravel PHP, YAML or gettext locale files lack, and the languages that lack them.

After each commit the model makes, names the manifests whose dependencies it changed without their lockfile (npm, Composer, Cargo, Go, Python, Bundler, Dart, Mix).

Loads MEMORY.md into the session and saves project learnings to it after every turn through a tool-less fork in the background, without blocking the stop.

Keeps project and global memories in SQLite through a shared local daemon, hands the model the entries that match its file tool calls, prompts and subagent tasks, and saves new ones with a haiku consolidator after each main-loop turn.

Opens one shared pane beside the transcript and draws the sections, lines and buttons every other mod writes into it through $.sidebar; each stream entry is stamped with its time and kept in a per-project log the next session takes back.

After an edit that builds SQL by joining or interpolating strings, names each line, so the model passes the values as query parameters.

After an edit that keeps browser data in localStorage or sessionStorage, names each line, so the model stores the data in a cookie instead.

Asks before Claude edits a file another chat on this machine changed in the last 30 minutes. Each chat keeps its own small ledger; no model calls, no network.
