More from kzarzycki/claude-mods
agent-hub
kzarzycki/claude-mods
Agent hub: a pane listing this session's subagents with status, model, turns and tokens, and a box to steer a running one.
auto-effort
kzarzycki/claude-mods
Auto effort: the decision model rates each prompt and the turn it starts runs at that effort.
compact-methods
kzarzycki/claude-mods
oh-my-pi compaction methods: shake (move old tool output to files, no model call) and handoff (continue from a handoff document). Use /compact shake or /compact handoff [focus].
decision-model
kzarzycki/claude-mods
A decision model for other mods ($.decision.ask): typed questions about a state, answered by any System One endpoint (Jev by default) or a small Claude model.
resume-on-stop
kzarzycki/claude-mods
Unexpected stops: when a turn ends right after saying it will act, the decision model spots it and one turn resumes the work.
ttsr-rules
kzarzycki/claude-mods
oh-my-pi TTSR rules: a regex rule denies the tool call that would break it, with the rule as the reason; a question rule is judged after each turn.
