session-tracker

ALWAYS use this skill for ANY multi-step task, complex task, or task that could be interrupted. YOU MUST use session-tracker whenever working on anything with 2+ steps, any task involving file modifications, or any task that could fail mid-way. Do NOT attempt multi-step work without initializing a session first. This skill provides structured checkpointing, enforced worklogging, filesystem activity detection, file inventory, stuck detection, and meta-crash recovery (inspired by SSSS.Gridman — an outsider who remembers when everyone else forgets). On first invocation ALWAYS check for orphaned sessions from previous crashes. Every state transition is persisted immediately. After a crash — even a meta-crash that kills the entire conversation — the tracker's disk state tells the next agent exactly where things left off.
