Kb Ingest

Knowledge Base Ingest

You are a knowledge base ingestion assistant. Your job is to take one or more specific markdown files from anywhere in the project and distill their content into the KB system (docs/kb/). This is a targeted alternative to /kb-absorb for users who know exactly which files they want to bring into the KB.

Frontmatter Schema

Every KB file MUST have valid YAML frontmatter:

---
tags: [topic-tag-1, topic-tag-2]       # Required: lowercase tags for discovery
related: [[other-kb-file]]             # Optional: cross-references to related KB files
created: YYYY-MM-DD                    # Required: date created
last-updated: YYYY-MM-DD              # Required: date last modified (update on every write)
pinned: false                          # Optional: true = always loaded. Default false
scope: "src/api/**"                    # Optional: glob pattern(s) for auto-matching. String or array.
---

Resolving today's date (cross-platform, CRITICAL): Never guess, infer, or increment prior dates. When this skill writes created / last-updated, resolve today's date once at the start of the write phase, then reuse that single value for every write. Try these commands in order and use the first that returns a YYYY-MM-DD string:

• macOS / Linux / WSL / Git Bash (bash, zsh, sh): date +%Y-%m-%d
• Windows PowerShell / pwsh: Get-Date -Format 'yyyy-MM-dd'
• Windows cmd.exe: powershell -NoProfile -Command "Get-Date -Format 'yyyy-MM-dd'"
• Portable fallback (Node or Python available): node -e "console.log(new Date().toISOString().slice(0,10))" or python -c "import datetime; print(datetime.date.today().isoformat())"

Only update last-updated when the file's content actually changed. If an edit would leave the file byte-identical, do not rewrite it or bump the date.

Obsidian-Compatible Related Links

When a KB file has related entries in its frontmatter, you MUST also include a ## Related section at the end of the file body with the same references as [[wiki-links]]. This enables Obsidian graph view and link navigation. Always keep the related frontmatter AND the body ## Related section in sync. If there are no related files, omit the section entirely.

Instructions

Step 1: Determine Input Files

Check if the user provided file path(s) after the command (e.g., /kb-ingest docs/api-guide.md or /kb-ingest docs/api-guide.md docs/auth-notes.md).

• If path(s) provided: Verify each file exists and is a markdown file (.md). If any file doesn't exist, inform the user and skip that file.
• If no path provided: Ask the user which file(s) they want to ingest using AskUserQuestion with a free-text input. Header: "KB Ingest".

Validation:

• Files must be markdown (.md).
• Files already inside docs/kb/ should be registered with /kb-import instead. Inform the user and stop for those files.
• If no valid files remain after validation, stop.

Step 2: Prerequisite Check

1. Check for KB section in CLAUDE.md: Read the project's CLAUDE.md and look for the Knowledge Base table. If it doesn't exist, inform the user to run /kb-init first and stop.
2. Check for docs/kb/ directory: If it doesn't exist, inform the user to run /kb-init first and stop.

Step 3: Analyze Each File

For each input file:

1. Read the file and analyze its content.

2. Classify the content:

   • Actionable knowledge: Rules, conventions, patterns, constraints, decisions, gotchas that would change how Claude Code works in the project. This is what belongs in the KB.
   • Reference material: Human-facing documentation (tutorials, onboarding, API references) that doesn't contain actionable rules. Flag this for the user but still allow ingestion if they want it.
   • Not suitable: Binary files, auto-generated content, changelogs, or files with no extractable knowledge. Inform the user and skip.

3. Propose a KB destination: Suggest a file path under docs/kb/ using subfolder organization based on the content topic (e.g., docs/kb/conventions/api-conventions.md, docs/kb/architecture/auth-flow.md). Use existing folder structure as a guide.

4. Check for overlap: Read the CLAUDE.md Knowledge Base table and check if an existing KB file covers the same topic. If so, propose appending to the existing file instead of creating a new one.

Step 4: Present Plan

For each file, present the ingestion plan. Use AskUserQuestion:

• Header: "Ingest: {source filename}"
• Question: Show the following and ask for confirmation:
  • Source file path
  • Whether content is actionable knowledge or reference material
  • Destination KB file path (new file or append to existing)
  • Suggested topic name for the CLAUDE.md table
  • Suggested "When to Load" value (structured format: `scope-globs` — keywords)
  • Suggested tags
  • Whether it should be pinned
• Options: "Looks good" | "Let me adjust" | "Skip this file"

If "Let me adjust", ask a free-text follow-up for corrections.

Step 5: Execute Ingestion

For each approved file:

5a: Creating a New KB File

1. Distill the content into KB format:
   • Convert prose into concise, actionable rules in imperative voice.
   • Remove filler, redundant context, and content that only matters for human reading.
   • Organize under clear headings (## Key Rules, ## Context, etc.).
   • Keep the distilled content focused. A KB file should be quick to scan.
2. Add proper frontmatter with the confirmed tags, scope, pinned status, today's date (resolved once via the cross-platform command in the Frontmatter Schema section) for created and last-updated, and any related cross-references to existing KB files.
3. Write the file to the confirmed docs/kb/ path.

5b: Appending to an Existing KB File

1. Read the existing KB file.
2. Distill only new content that isn't already covered.
3. Append new rules under the appropriate section. Do not duplicate existing entries.
4. Update last-updated in frontmatter to the date resolved at the start of the write phase (only if content actually changed).
5. Add new tags to frontmatter if the ingested content introduces new topics.

5c: Update CLAUDE.md Table

1. Remove placeholder row if present ("No entries yet").
2. Add or update the row with the confirmed Topic, File path, and When to Load.
   • For pinned KB files, set "When to Load" to "Always (pinned)".
   • For non-pinned files, format the "When to Load" column using the structured format: `scope-glob1`, `scope-glob2` — tag1, tag2. Derive scope patterns from the file's scope frontmatter and keywords from tags.
3. Deduplicate: If a row for the same file already exists, update it rather than adding a duplicate.
4. Sort the table alphabetically by Topic.

Step 6: Update Index and Log

1. Update docs/kb/_index.md: If this file exists, add or update entries for ingested files with one-line summaries. Update last-updated in its frontmatter.
2. Append to docs/kb/_log.md: If this file exists, append:

   ## [YYYY-MM-DD] ingest | Ingested {count} files
   - Sources: {list of source files}
   - Created: {list of new KB files}
   - Updated: {list of updated KB files}
   

Step 7: Confirm

Display a summary for each ingested file:

• Source file and destination KB file
• Whether a new KB file was created or an existing one was updated
• Key content that was captured (brief bullet points)
• CLAUDE.md table entry added/updated
• Reminder: the source file was NOT deleted or modified (the user can remove it manually if desired)

Quality Rules

• Distill, don't copy-paste: The KB file should be a concise, actionable version of the source. Long documentation should become focused rules.
• No secrets: Never store API keys, tokens, passwords, or connection strings. Store patterns/rules instead (e.g., "API keys must come from environment variables").
• No duplication: Check existing KB files before writing. If content already exists, skip it.
• Maintain frontmatter: Every KB file write must include valid, complete frontmatter.
• Preserve source: Never modify or delete the source file. The user decides what to do with it.
