Wiki Update

Revise existing wiki pages. Always show diffs before writing. Always log. Always cite the source of new information.

Pre-condition

Find SCHEMA.md (search from cwd upward, or ~/wikis/). If not found, tell the user to run wiki-init first. Read it to get wiki root path and conventions.

Process

1. Identify what to update

The user may provide:

• Specific page names — update those pages
• New information — read wiki/index.md to find affected pages, then read those pages
• A lint report — work through its recommendations item by item

2. For each page to update

Read the current content in full. Propose the change:

Current: <quote the existing text> Proposed: <replacement text> Reason: <why this change is warranted> Source: <URL, file path, or description of where this information comes from>

Always include Source. An edit without a source citation creates untraceability — future you won't know why the change was made.

Ask for confirmation before writing each page. Do not batch-apply changes without per-page confirmation.

3. Check for downstream effects

After identifying the primary pages to update, grep for [[slug]] references to those pages across all of wiki/pages/. For each page that links to an updated page:

• Does the update change anything that page asserts?
• If yes: flag it explicitly — "[[other-page]] may also need updating based on this change"
• Offer to update it with the same confirm-before-write flow

4. Contradiction sweep

If the new information contradicts something in the wiki: search all pages for the contradicted claim before updating. It may appear in more than one place. Update all occurrences, not just the most obvious one.

5. Update wiki/index.md

If the one-line summary for any updated page has changed, update it in index.md. Update the updated date in the page's frontmatter.

6. Update wiki/overview.md

Re-read overview.md. If the updates shift the overall synthesis (new understanding, resolved open question, changed key claim), propose edits to overview.md using the same confirm-before-write flow.

7. Append to wiki/log.md

Always append — do not ask permission, do not skip if log.md exists:

## [<today>] update | <list of updated page slugs>
Reason: <brief description of what changed and why>
Source: <URL or description>

Common Mistakes

• Updating without citing the source — Always include where the new information came from. This makes the wiki auditable.
• Skipping the downstream check — An update that contradicts a page's content while leaving pages that link to it unchanged creates silent inconsistency.
• Skipping the log — Every change must be logged. The log is append-only; if log.md doesn't exist, create it.
• Batch-writing without confirmation — Show each diff individually. The user may accept some changes and reject others.
• Appending instead of updating — Do not add ## [date] update sections to page bodies. Edit the relevant section in-place, bump the updated frontmatter date, and log the change in log.md. If you find existing date-stamped sections, offer to integrate them in-place as part of the update.
