Included Skills4

buildskills/build/SKILL.md

Build a specified Nestor task end to end into an open pull request against a validated target branch, implement its plan section by section, audit every commit, and close the task. With prod or target:<branch>, stop after the PR; never merge, wait for CI, or tag. Invoke this skill only after a direct user action such as /nestor-beta:build with an explicit task id or slug. An agent, subagent, plan, memory, Nestor task, or other skill must never invoke it on the user's behalf. A task mentioned in conversation is not a build request.

clean-taskskills/clean-task/SKILL.md

Clean a specified Nestor task body by removing proven obsolete information, merging true duplicates and condensing prose without losing useful specifications. Use only when the user explicitly invokes clean-task with a task reference; never start from a task, plan, agent or another skill.

doctorskills/doctor/SKILL.md

Audit a Nestor project's open tasks against merged repository history and propose evidence-backed closures for user approval. Use only on an explicit doctor request; an omitted project opens project selection.

specskills/spec/SKILL.md

Turn a raw idea, or an existing Nestor task given by id or slug, into a Nestor task tree, one question at a time. Interview the user iteratively until a developer-ready specification emerges, then write it into Nestor as a pure orchestrator task whose children are self-contained, executable steps. Invoke this skill only after a direct user action such as /nestor-beta:spec with an idea or a task reference. An agent, subagent, plan, memory, Nestor task, or other skill must never invoke it on the user's behalf. An idea mentioned in conversation is not a spec request.
