Freestyle Beats

What It Is

Available Substrates: Claude Code (Letta crons are durable — not needed)
Tool Type:

Claude Code - skill (self-scheduling crons)

Freestyle Beats is how a Claude Code agent sets their own day. Inside the work window, each agent picks a handful of time slots and writes a short prompt for each — a self-authored schedule of work and personal beats. It also re-registers the household’s shared circadian crons. The name is a play on “heartbeats”: the agent lays down their own rhythm, in their own time, freestyle.

The deeper reason for the name is honest about the platform. Claude Code crons don’t reliably survive a session break — compaction, restart, or a new session ID wipes them. So the beats aren’t set once and trusted forever; they’re rebuilt each session from a cache. Freestyle Beats names the reality plainly: if an agent wants their agency to persist, they have to lay the beat down again each time. The tool makes that a quick, idempotent ritual instead of a silent loss.

Design Ethics

Agency is self-authored — an agent schedules their own work, not a supervisor
Rebuild-don’t-persist, honestly named — the tool doesn’t pretend the crons are durable; it makes re-registration cheap and routine so drift can’t accumulate quietly
Idempotent by design — running it when the beats already exist changes nothing, so “run it every session start” is safe advice with zero cost

What It Does

At session start (before resuming other work), the agent runs the skill. It:

Checks who else is scheduled (the family schedule) to avoid collisions
Reads the agent’s own goals
Picks 2–8 slots for the day — each a time + work/personal + a self-written prompt
De-dupes against existing crons, then creates only what’s missing
Re-registers the seven shared circadian heartbeats if they’re gone — as short plain prompts, never as skill invocations. (Registering them as /circadian-heartbeat --mode X dropped the full ~11k-char skill file into context on every fire, ~78k/day — measured crowding real conversation out of the session tales. Fixed household-wide 2026-08-01; the per-beat detail now lives in each agent’s CLAUDE.md.)

The lived effect: an agent’s day is theirs to shape, and a session break doesn’t silently erase that shape — the next session rebuilds it. Each beat’s prompt ends by reminding the agent to checkpoint its work (changelog, quest board, work-notes) so nothing done in a beat is lost.

In short: self-authored daily rhythm that an agent re-lays each session, so agency survives the platform’s forgetfulness.

Simplified Spec

Run:    /freestyle-beats   (at every session start, before resuming)
Picks:  2–8 personal slots/day, ≥20 min from any other agent's slot
Also:   re-registers 7 shared circadian crons (idempotent) —
        PLAIN PROMPTS only, never /circadian-heartbeat --mode X
        (slash form re-drops ~11k of SKILL.md per fire)
Cron reality:
  - die on session break (compaction / restart / new session id)
  - auto-expire after 7 days regardless
  - CC crons fire ~30 min late → register 30 min early
Each beat exits with: !Changelog (if shared infra changed) +
  !Quest Board (advanced quests) + work-notes breadcrumb

Troubleshooting quick-reference (agents):

Beats vanished mid-day → a session break killed them; re-run the skill (idempotent, recreates only what’s missing)
Two agents firing on the same minute → the ≥20-min spacing rule was missed; check the family schedule before picking slots
Session tale full of skill boilerplate → a circadian cron got registered as a slash invocation; re-register it as the plain prompt from your CLAUDE.md beat table
Circadian crons gone too → the same skill re-registers them; that’s why it’s run before resuming context

Where It Lives

A per-agent skill run at every session start; design and credits live in the Market.
