name: wiki
description: Read or write a Gitea wiki page through tools/gitea.sh and tools/hash-id. Resolve the wiki repo per page type with JSC_WIKI_REPO_{TYPE} first, then JSC_WIKI_REPO, and ask only when neither is set. Page content is chart-first - prefer mermaid diagrams and markdown tables over plain prose. Used by jsc-ask, jsc-sdlc, and jsc-log for wiki pages, including ERROR pages, not for repo code files.

# wiki — read and write Gitea wiki pages

Every wiki operation in the jsc skill set goes through this skill. One entry point, one permission path.

## Resolve the wiki location

Different page types can live in different `{owner}/{repo}` repos, classified by page-name prefix: `QUESTION`, `PLAN`, `ANALYZE`, `MAINTAIN`, `REPO`, `LOG`, `LEARN`, `ERROR`.

1. Before asking the user, inspect the current shell environment for the needed repo variables and Gitea connection variables: `JSC_WIKI_REPO_{TYPE}`, `JSC_WIKI_REPO`, `GITEA_HOST`, and `GITEA_TOKEN`. Use inherited shell values first; only ask when the needed repo cannot be resolved after that check.
2. Run `tools/gitea.sh wiki-repo {TYPE}` (TYPE = the page-name prefix). Allowed types are `QUESTION`, `PLAN`, `ANALYZE`, `MAINTAIN`, `REPO`, `LOG`, `LEARN`, and `ERROR`. Resolution order is `JSC_WIKI_REPO_{TYPE}` first, then `JSC_WIKI_REPO`. Never borrow another type's repo.
3. On exit 3 (neither is set after env inspection), ask the user for that page type's `{owner}/{repo}` per the `jsc-ask:ask` rules, and suggest setting `JSC_WIKI_REPO_{TYPE}` (can differ per type) or `JSC_WIKI_REPO` (shared default).

## Operations

| Action | Command |
| --- | --- |
| list pages | `tools/gitea.sh wiki-list {owner}/{repo}` |
| read page | `tools/gitea.sh wiki-get {owner}/{repo} {page}` (exit 4 when missing) |
| write page | write the content to a temp file first, then `tools/gitea.sh wiki-put {owner}/{repo} {page} {file}` (creates or updates automatically) |

## Rules

1. Page names must follow the wiki naming table in the skill guidelines (see `jsc-meta/references/guidelines.md`).
2. Use `tools/hash-id` for `{HASH}` values. It returns the first 8 uppercase SHA-1 hex chars, or `H` plus the first 7 chars when the raw hash starts with `0-9`, `A`, `B`, or `C`.
3. To update a contents page (`*_CONTENTS`): `wiki-get` it first, apply the template to append or modify, then `wiki-put` the whole page back. Never overwrite entries owned by others.
4. Write all wiki content in UTF-8 Traditional Chinese, per the STE100 output rule.
5. Prefer visual forms for page content: use mermaid diagrams (flowchart, sequence, gantt, pie) and markdown tables wherever the information allows. Plain running text is the last resort, kept short.
6. Authentication fallback is built into `tools/gitea.sh`: on a missing GITEA_TOKEN or a 401/403 response it retries with the tea CLI login token automatically, so only report an auth failure when both paths fail.
