plan	SDLC planning stage. Gate on model capability tags, pick or create a plan from PLAN_CONTENTS, then run a decision tree until goal, scope, and feasibility reach consensus. Produce user stories into wiki page PLAN_{yyyyMMdd}_{HHmmss}_{HASH}. Logic only - never write code or modify files. Use when the user wants to start or refine a plan; not for analysis or implementation.

plan

Goal: create or extend the wiki plan page PLAN_{yyyyMMdd}_{HHmmss}_{HASH}. This skill is a logic-only stage: never output code, and never modify any file.

{HASH} = first 8 chars of the SHA-1 of {owner}/{repo}, uppercase. All wiki reads and writes go through jsc-gitea:wiki.

Steps

1. Model capability gate: check the capability tags from jsc-cli:models and confirm the current model qualifies for planning. If not, block the flow and tell the user which model to switch to.
2. Read PLAN_CONTENTS via jsc-gitea:wiki and list the plans whose status is the literal 「未分析」 (not analyzed), with names and HASH.
3. Let the user choose per jsc-ask:ask rules: extend an existing plan (list the not-analyzed plans as options) or create a new plan. State the impact scope on every option.
4. Question via the jsc-ask:ask decision tree until no doubt remains on all three items; keep asking while consensus is missing:
   • Goal: the problem to solve and the criteria for success.
   • Scope: what is included, what is excluded, which repositories are involved.
   • Feasibility: whether the system architecture and data sources support the goal.
5. Turn the consensus into user stories (the zh-TW pattern 「身為⋯⋯我想要⋯⋯以便⋯⋯」), one per line.
6. Apply templates/plan-page.md to create or update the plan page, and write it back via jsc-gitea:wiki. The page content is Traditional Chinese, exactly as the template dictates.
7. If the plan page is new, add it to PLAN_CONTENTS using the entry format of templates/plan-contents.md, with status set to the literal 「未分析」.

Hard limits

• Never output a code snippet.
• Never modify any file in the working directory.
• Never skip the decision tree and assume requirements.
