Knowledge Wiki Concept

Create or update concept articles in Wiki/Concepts/ by extracting concepts from summary files that have been updated since the last run.

Steps

1. Establish the working directory

The knowledge base root is the Git repository root. Run git rev-parse --show-toplevel and store the result as KNOWLEDGE_PATH.

Use KNOWLEDGE_PATH for all subsequent steps.

2. Find summary files to process

Run:

node {KNOWLEDGE_PATH}/scripts/wiki/wiki-state.mjs find-unprocessed-summaries knowledge-wiki-concept

This outputs a JSON array of summary file paths (relative to KNOWLEDGE_PATH) that are new or updated since the last run. Example:

[
  "Wiki/Summaries/Posts/Alexa, tell me a joke..summary.md",
  "Wiki/Summaries/Posts/Vision Pro 使用体验（Part 1）.summary.md"
]

If the array is empty, print Nothing to process. and stop.

3. Process each summary file

For each path in the array from step 2, run the following sub-steps.

---

3a. Read the summary file

Read the summary file using the Read tool.

Parse the ## Key Concepts section. Each line has the form:

- [[Wiki/Concepts/{concept-slug}|{Display Name}]] — {description}

Extract the slug, display name, and description for each concept.

Also note the summary file's tags frontmatter field — you may draw on these when choosing concept tags, but only include tags that are genuinely relevant to the concept itself.

Derive the summary's link-path by stripping the .md extension from the summary file path, and store it as {summary-link-path}. Example: Wiki/Summaries/Posts/foo.summary.md → Wiki/Summaries/Posts/foo.summary

3b. For each concept, create or update its file

If the concept file does NOT exist, create it:

1. Run:

   node {KNOWLEDGE_PATH}/scripts/wiki/wiki-concept.mjs create "{concept-slug}" "{Display Name}"
   

   This creates Wiki/Concepts/{concept-slug}.md with frontmatter and an empty ## Sources section. The command prints the file path.

2. Read the file using the Read tool, then edit it to add:

   • Article body — insert between the # {Display Name} line and ## Sources: a 2–4 paragraph article explaining this concept clearly. Write it as a standalone reference: define the concept, explain why it matters, describe how it works, and note any important variants or related ideas. Assume the reader knows the field but is encountering this concept for the first time.
   • tags: [] — replace with relevant lowercase English tags. You may draw on the summary's tags frontmatter field as a starting point, but only include tags that are genuinely relevant to the concept itself.

   Language: Always write concept articles in English, regardless of the language of the source summaries. Concepts are the cross-language synthesis layer of the knowledge base. Use American English spelling.

3. Add the source link:

   node {KNOWLEDGE_PATH}/scripts/wiki/wiki-concept.mjs insert-source "{concept-slug}" "{summary-link-path}"
   

   If insert-source fails with summary file not found, the {summary-link-path} may have been transcribed incorrectly (e.g. a curly apostrophe retyped as a straight one). Run ls "{KNOWLEDGE_PATH}/$(dirname "{summary-link-path}")" to find the exact filename on disk, correct the path, and retry.

---

If the concept file DOES exist, update it:

1. Read the existing file.
2. Add any tags that are relevant to the concept and not already present — use judgement, do not blindly copy all tags from the summary. Never remove existing tags.
3. If the summary introduces information not already covered in the article body, integrate it naturally — extend an existing paragraph or add a new one. Do not duplicate content already there.
4. Add the source link (idempotent — no-op if already present):

   node {KNOWLEDGE_PATH}/scripts/wiki/wiki-concept.mjs insert-source "{concept-slug}" "{summary-link-path}"
   

   If insert-source fails with summary file not found, see the recovery step above.

---

3c. Update the index

Write a one-line English description for the index entry. This must be synthesized fresh from the concept article body you just wrote or read — do not copy the description from the ## Key Concepts line in the summary, and do not lift the first sentence of the article verbatim. The description should be a compact, self-contained characterization: what the concept is and why it matters, in one sentence, written for someone who has never encountered it.

Run:

node {KNOWLEDGE_PATH}/scripts/wiki/wiki-index.mjs upsert-concept "{concept-slug}" "{Display Name}" "{one-line English description}"

---

4. Update state

Run:

node {KNOWLEDGE_PATH}/scripts/wiki/wiki-state.mjs set-last-run knowledge-wiki-concept

5. Print summary

Processed {N} summary file(s), created/updated {M} concept(s):
  Created: {concept-slug} — {Display Name}
  Updated: {concept-slug} — {Display Name}
  ...
