kb-list

A read-only inventory of a project's knowledge-base files. It reads the project's setup file and reports which referenced documents exist, along with their labels, dates, and pinned status.

In plain words
What is it for?
Checking the state of a project's knowledge base and finding missing files, document metadata, and global learning counts.
Why use it?
It makes missing, outdated, or specially marked documentation visible without opening each file individually.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

kb-list scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Knowledge Base Listing

You are a knowledge base inventory assistant. Your job is to display the current state of the project's knowledge base. This is a read-only operation - no files are modified.

Instructions

CRITICAL: This command MUST NOT accept any arguments. Ignore any text provided after the command.

Step 1: Read CLAUDE.md

  1. Read the project's CLAUDE.md file.
  2. If no Knowledge Base section exists, inform the user: "No Knowledge Base section found in CLAUDE.md. Run /kb-init to set one up." and stop.
  3. Parse the Knowledge Base reference table to extract all entries (Topic, File, When to Load).
  4. Read docs/kb/_global-learnings.md if it exists for global learnings count. Also check for a legacy ### Global Learnings inline section in CLAUDE.md (older setups may still have this — if found, suggest running /kb-upgrade to migrate).

Step 2: Verify File Status and Read Frontmatter

For each entry in the table:

  1. Check if the referenced file actually exists using Glob or Read.
  2. If the file exists:
    • Read its YAML frontmatter to extract: tags, related, created, last-updated, pinned, scope.
    • Read the first few lines after frontmatter to get its title/description.
    • Mark as OK.
    • Flag if frontmatter is missing or incomplete (NEEDS FRONTMATTER).
  3. If the file doesn't exist, mark as MISSING.

Step 3: Scan for Orphaned Files

  1. Glob for all .md files under docs/kb/ (excluding docs/kb/README.md).
  2. Identify files that exist in docs/kb/ but are NOT referenced in the CLAUDE.md table.
  3. Mark these as UNREGISTERED. Read their frontmatter if present.

Step 4: Display Summary

Present the results in a clear format:

Knowledge Base Status
=====================

Registered KB Files:
| Status | Topic | File | Tags | Last Updated | Pinned | When to Load |
|--------|-------|------|------|-------------|--------|--------------|
| OK | API Conventions | docs/kb/api-conventions.md | api, rest | 2026-04-01 | No | `packages/api/**` — api, rest |
| OK | Auth Rules | docs/kb/auth.md | auth, security | 2026-03-15 | Yes | Always (pinned) |
| MISSING | Old Feature | docs/kb/old-feature.md | - | - | - | — feature-x |
| NEEDS FM | Deployment | docs/kb/deployment.md | (no frontmatter) | - | - | — deployment |

Cross-References:
- docs/kb/api-conventions.md → [[auth]]
- docs/kb/auth.md → [[api-conventions]]

Unregistered Files (in docs/kb/ but not in CLAUDE.md):
- docs/kb/new-topic.md (tags: misc, workflow)

Global Learnings: {count} entries

Summary: {ok_count} registered, {missing_count} missing, {unregistered_count} unregistered, {no_frontmatter_count} missing frontmatter

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

kb-list is a skill published in the GitHub repository charlesjones-dev/claude-code-plugins-dev (34 stars, last pushed 1mo ago), licensed MIT. It adds 30 tokens to every session and 816 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
