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

rk-memo 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 11d 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.

RK Memo — Save Personal Knowledge

Store a piece of personal knowledge that isn't tied to any codebase.

Input

Free-form: <title>: <content> or just natural text describing what to save.

Step 1: Resolve home directory (cross-platform)

python3 -c "import os; print(os.path.expanduser('~'))"

Store as {HOME}. Base path: {HOME}/.repo-knowledge.

Step 2: Initialize _personal project if it doesn't exist

Check if {HOME}/.repo-knowledge/_personal/ exists.

If not, create it:

Use Write tool to create {HOME}/.repo-knowledge/_personal/_meta.md:

type: personal
git_url: none
created: {YYYY-MM-DD}
last_update: {YYYY-MM-DD}
total_docs: 0

Use Write tool to create {HOME}/.repo-knowledge/_personal/_index.md:

# _personal Knowledge Index

Add entry to {HOME}/.repo-knowledge/_registry.md:

| _personal | (personal) | {YYYY-MM-DD} | 0 |

Also create the docs directory by writing a placeholder if needed.

Step 3: Derive doc filename

Convert the title to kebab-case:

  • Lowercase
  • Replace spaces and special characters with -
  • Remove consecutive dashes

Example: kubectl 查看 pod 状态kubectl-pod-status

Check if {HOME}/.repo-knowledge/_personal/docs/<kebab-name>.md already exists. If it exists: this is an update — overwrite the existing doc. If not: this is a new entry.

Step 4: Write the doc

Use Write tool to save {HOME}/.repo-knowledge/_personal/docs/<kebab-name>.md:

---
cached: {YYYY-MM-DD}
source: personal
---

## {title}

{content}

Keep content exactly as the user provided. If the user gave a code snippet, preserve it as a fenced code block with appropriate language tag.

Step 5: Update _index.md

For new entries: append to {HOME}/.repo-knowledge/_personal/_index.md:

- [{title}](docs/<kebab-name>.md) — {one-line summary}
  aliases: [{title}, {key terms extracted from content}]

For existing entries (update): find the line with this doc path and update the description. Keep existing aliases, prepend the new title as alias if it changed.

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.
