description: SDLC planning stage. Gate on capability tags enforced in code by sdlc-gate (plan requires reasoning-max, verified against the transcript's actual model id), 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_{HASH}, then close with tools/stage-report.sh - model tag verdict, worklog link, every wiki link written. 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_{HASH}`.
This skill is a **logic-only** stage: never output code, and **never modify any file**.

`{HASH}` = the shared wiki hash for `{owner}/{repo}` used to build the `PLAN_{HASH}` page name, computed by `jsc-gitea/tools/hash-id` (see `jsc-gitea:wiki`).
All wiki reads and writes go through `jsc-gitea:wiki`.

## Steps

1. **Model gate and stage lock** — run `jsc-cli/tools/model-tags.sh sync`, then `jsc-hooks/hooks/sdlc-gate.sh lock plan`. This stage requires the `reasoning-max` capability tag. Rules: `references/model-gate.md`. Completion condition: the script exited 0, and you have reported the stage, the required tag, the actual model id it read from the transcript, and the verdict.
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. Completion condition: you have listed every 未分析 plan with its name and HASH, or reported that none exists.
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. Completion condition: the user has picked one option explicitly, and you have named the `PLAN_{HASH}` page this run writes to.
4. **Keep questioning until consensus** — rules in `references/consensus.md`, which is the single authority for both planning and analysis. Cover all three items:
   - 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.

   **One round is never enough**: every answer must produce the next question, derived from what that answer just exposed. Never fill a gap with your own assumption, and never move on to user stories while any item is still open.

   Completion condition: all three items are settled under both conditions of `references/consensus.md` — no remaining unknown that would change the output, **and** the user's explicit confirmation of the summary you read back.
5. Turn the consensus into **user stories** (the zh-TW pattern 「身為⋯⋯我想要⋯⋯以便⋯⋯」), one per line. Completion condition: every consensus item is covered by at least one user story in that pattern, and no user story rests on an unanswered question.
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. Completion condition: the page is saved on the wiki and carries every section the template dictates — goal, scope, feasibility, user stories and the consensus summary — with no placeholder left unfilled.
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」. Completion condition: `PLAN_CONTENTS` shows the plan's row with the literal 「未分析」, saved on the wiki.
8. **Stage report — the last thing this stage does, including every early stop** (the model gate blocked, no plan was selectable). Run `tools/stage-report.sh plan` with one `--page PLAN:{page}` per wiki page this run wrote (`PLAN_{HASH}` and `PLAN_CONTENTS` both count), plus `--worklog` and `--worklog-heading` when a work log entry exists. No work log yet: write this stage's log content to a file and pass `--pending-file {file} --log-hash {HASH}` so it is held for the next `jsc-log:worklog` run. Rules and exit codes: `references/stage-report.md`. Exit 1 is a warning, never a block. Completion condition: the script's output is reported to the user verbatim, and every wiki page this run wrote appears in it.

## Hard limits

- Never output a code snippet.
- Never modify any file in the working directory.
- Never skip the decision tree and assume requirements.
- Never stop questioning after one round; consensus is reached only under `references/consensus.md`, and the user says so.
