What this skill does for you
Monitors task execution for skill improvement opportunities. Use during ANY multi-step task, agentic workflow, or work session. Captures patterns, user corrections and methodology worth preserving as reusable skills. Also triggers in post-task feedback discussions and when the user mentions skill observations, the observation log, or skill taxonomy. Also known as "One Skill to Rule Them All" : trigger on this phrase too. IMPORTANT: invoke this skill before the FIRST tool call of any session and before writing or proposing a plan : any turn that will involve a tool call counts. This sentence is the session-start trigger and the only activation layer that survives an unreachable config file; pair it with a CLAUDE.md instruction or a harness session-start hook (references/environments.md) : description matching alone is not enforceable.

Set up Edge for me: read getedge.cc/SKILL.md and follow it. Then use Edge to load the task-observer skill from rebelytics/one-skill-to-rule-them-all.
Paste it into Claude, ChatGPT, Codex or Cursor.
Or read the skill source first.
