Mods

A mod is a small plugin that adds a status line, a pane or a command inside Claude Code. Skills run a workflow; mods change what you can see and do while the workflow runs. They are installed from a plugin marketplace, not with skills.sh, and they only act in the session where they are installed.

bq-vitals

Shows what a reactive skill run is doing from inside Claude Code: a status line with context, cost and rate limits, a live map of the state machine, and a query-plan style trace of the path the run took.

install

$/plugin install bq-vitals --marketplace Reactive-Skills/reactive-skills

Answer y to add the marketplace, then pick a scope. Source

Status line: Context used, session cost and rate-limit windows, with the active skill and state appended while a run is in progress.
/flow: Opens a pane with a live map of the state machine (done, current, not reached) above the plan trace. It refreshes every few seconds.
/flow-plan: Prints the path the latest run took, one line per hop: the signal, whether the guard passed, time spent in the state, and the exits that were not taken.

Claude Code status line reading bq-vitals: ctx 246k/1.0M 25%, $6.10, 5h 2%, 7d 49% — The status line: context, cost and rate limits.

Output of /flow-plan for a caption-summarizer run: seven hops from INIT to COMPLETE with time per state and the exits not taken — /flow-plan on a finished run: the path taken, time per state and the exits not taken.

What it reads

.reactive/skills/<skill>/events.jsonl, the append-only event ledger of the run
STATECHART.md in the skill's directory, for the edges a state could have taken

It only reads. It looks in the session directory, ~/.claude/skills, ~/.agents/skills and /tmp for the latest run.
