A command for recording project knowledge as a categorized Markdown note.

Use it to create a dated entry in the selected category, add its metadata and content, and update the knowledge-base index.

It prevents important decisions, solutions, issues, patterns, corrections, or background information from being lost between sessions.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

Made for: Claude Code.

Or install knowledge-base, the plugin that ships this one along with the rest of its 1 skill, 3 commands, 1 agent.

Per session 12 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 459 The whole file, excluding the scripts and references it only reads on demand.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00012	$0.00459
Opus 5.5	$0.00005	$0.00184
Sonnet 5.5	$0.00002	$0.00092
Haiku 4.5	$0.00001	$0.00046

Security

Grade A, and why

kb-add 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 2mo 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.

What it actually says

Create a new knowledge base entry with proper formatting and categorization.

Instructions

Read configuration from .claude/knowledge-base.local.md to get kb_path (default: ~/.claude/knowledge-base/)
If the knowledge base directory doesn't exist, create it with all category subdirectories:
- decisions/, solutions/, issues/, patterns/, corrections/, context/
Parse the user's input:
- If category is provided (e.g., /kb-add decisions JWT选型), use it directly
- If only a title is given, ask the user to choose a category
- If no arguments, ask what knowledge to record
Create the entry file:
- Filename: YYYY-MM-DD-kebab-case-title.md (today's date)
- Location: {kb_path}/{category}/
- Use the YAML + Markdown format from the knowledge-management skill
- Fill in frontmatter: title, category, tags, created date
- Write the Background, Content, and Key Takeaways sections based on conversation context
After creating the entry, update _index.md:
- If _index.md doesn't exist, create it
- Add the new entry to the appropriate category section
- Sort entries by date within each category

Category Reference

Category	Use When
`decisions`	Recording architecture or design choices
`solutions`	Documenting a technical approach

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.
