Second Brain — Wiki Edit

Apply targeted edits to one or more wiki articles based on a natural-language instruction, while preserving all structural invariants.

Input

/second-brain-edit-wiki "<edit_prompt>" [<slug>]
  • edit_prompt — free-text description of the edit to apply (required)
  • slug — kebab-case wiki article filename without .md (optional)
    • If provided, the edit is applied only to that article
    • If omitted, the skill reads wiki/INDEX.md and infers which article(s) to edit from the prompt

Execution Steps

Step 1 — Parse and validate

  1. Extract edit_prompt from the first quoted argument.
  2. Extract optional slug from the second quoted argument.
  3. If slug is provided, verify wiki/<slug>.md exists. If not, stop with: ✗ Article not found: wiki/<slug>.md

Step 2 — Identify target article(s)

If slug is provided: target is wiki/<slug>.md only.

If slug is omitted:

  1. Read wiki/INDEX.md to get the full list of topics and their one-line summaries.
  2. Scan the edit_prompt for article names, topic references, or contradiction descriptions (e.g. "company-overview", "revenue figure", "headcount data").
  3. Match against INDEX entries. Select all articles that are plausibly relevant to the edit.
  4. If no match is found, stop with: ✗ Could not determine which article to edit from: "<edit_prompt>" Hint: re-run with an explicit slug, e.g. /second-brain-edit-wiki "<prompt>" company-overview

Step 3 — Apply edits

For each target article:

  1. Read the current content of wiki/<slug>.md.
  2. Apply the edit described in edit_prompt. Use good judgement to make the minimal, targeted change that satisfies the instruction.
  3. Preserve all invariants:
    • Summary paragraph — must remain the first paragraph after the # Heading. Never remove, replace with headings, or reorder.
    • Sources footer — the ---\n*Sources: ...* block at the end must remain byte-for-byte unchanged. Never modify, remove, or add to source references.
    • Wikilinks — all existing [[wikilinks]] must be preserved. You may add new ones; never remove without an explicit instruction to do so.
    • Section structure — preserve all ## Headings and their order unless the edit explicitly requires restructuring.
  4. Write the updated content back to wiki/<slug>.md.

Step 4 — Confirm

Output one status line per article edited:

✓ wiki/company-overview.md — Updated revenue figure in summary: "$120M" → "$134M (2024 actual)"
✓ wiki/product-strategy.md — Corrected launch date from Q3 to Q4 in Key Milestones section

For errors use ✗ prefix with a brief reason.

Invariants

  • Never delete or rename wiki articles
  • Never modify any file in raw/
  • Never alter the Sources footer
  • Never write to raw/edits/ or any other staging location — edits are in-place only
  • If the edit would require creating a new wiki article, note it in output but do not create it (suggest running /second-brain-ingest instead)
