…k mining Three filters to stop machine-generated prompts polluting the mined task pool (they dominated ~80% of tasks on this machine): - _is_meta_prompt: drop expanded slash-command bodies (<command-message> tags or '# /' headers) — plugin self-invocations are not user intents - _AGENT_SESSION_MARKERS + _is_agent_session: skip sessions whose first prompt is another tool's agent brief (claude-mem observers, CLAUDE.md critic sub-agents, SkillOpt-Sleep's own command body) - load walk: skip <session>/subagents/ dirs and agent-*.jsonl files — Agent-tool sidechain transcripts are Claude-authored, not user tasks Verified: harvest went from 120 sessions / mostly-noise tasks to 55 sessions / 38 real user tasks.

Problem
Harvest mines machine-generated prompts as if they were user tasks. On a machine with memory/observer plugins installed (e.g. claude-mem) and regular Agent-tool use, ~80% of mined tasks were not authored by the user:
<session>/subagents/agent-*.jsonl;os.walksweeps them in, so every Task/Agent spawn's prompt becomes a "recurring user task" (one session contributed 19 near-duplicate tasks).claude -pcalls and sub-agent fan-out as user tasks, inflating recurring-task signal #62 never catches them._is_meta_promptonly skips short/cmdforms, so the plugin's own/skillopt-sleepcommand body got mined as a task (self-harvest).Downstream effect: the optimizer trains and gates on prompts the user never wrote.
Fix
subagents/directories andagent-*.jsonlfiles in the transcript walk (structural, no heuristics)._AGENT_SESSION_MARKERS+_is_agent_session(): drop sessions whose FIRST user prompt is a known agent brief. Ships with markers for claude-mem and this plugin's own command; user-extensible viaSKILLOPT_SLEEP_AGENT_MARKERS(comma-separated), mirroring the existingSKILLOPT_SLEEP_NEG_FEEDBACKpattern._is_meta_prompt: also skip prompts containing<command-message>/<command-name>or starting with# /.Verification
On a real ~/.claude with claude-mem installed: harvest went from 120 sessions / mostly machine-generated tasks to 55 sessions / 38 tasks, all genuinely user-authored.
