Monitors task execution for skill improvement opportunities. Use during ANY multi-step task, agentic workflow, or work session where the agent uses tools and produces deliverables. Captures patterns, user corrections, workflow insights, and methodology worth preserving as reusable skills. Also triggers in post-task feedback discussions and when the user mentions skill observations, improvements, the observation log, skill taxonomy, or asks the agent to watch for skill opportunities. 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, however simple the opener looks. 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.

task-observer is a skill: instruction text plus a few shell snippets and Python scripts that an agent runs inside your workspace. It has no server, no network service and no credentials of its own. The security questions that matter are therefore about what the skill tells an agent to do on your machine.

source.A snippet that is merely wrong — reports the wrong count, breaks on an unusual shell — is a bug, not a vulnerability: open a normal issue.
Only the latest release on main receives fixes. Older tags are not
