A cleanup procedure that permanently removes a project's codebase knowledge base, cached documentation, cloned repository, and registry entry. A knowledge base is the stored project information used for later code queries.

Use it when someone asks to delete a knowledge base, remove a repository, or run rk-delete. It first requires confirmation, then removes the relevant cache and registry records.

It removes stored project data when it is no longer needed, including the local copy of a repository when one exists.

rk-delete — Skill for Claude Code by Sixz-AI

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.

Any agent

npx skills add Sixz-AI/repo-knowledge --skill rk-delete

Clone the repo

git clone --depth 1 https://github.com/Sixz-AI/repo-knowledge

Made for: Claude Code.

Or install repo-knowledge, the plugin that ships this one along with the rest of its 9 skills, 2 agents, 1 hook.

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	$0.00052	$0.00283
Opus 5	$0.00026	$0.00142
Sonnet 5	$0.00010	$0.00057
Haiku 4.5	$0.00005	$0.00028

Security

Grade C, and why

rk-delete scanned grade C with 1 finding 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 10d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

rm -rf ~/.repo-knowledge/<project-name>/

What it actually says

RK Delete — Remove Knowledge Base

Delete a project's knowledge base completely.

Input

Project name

Process

Step 1: Confirm with User

Ask: "Are you sure you want to delete the knowledge base for {project-name}? This will remove all cached documentation."

Step 2: Delete Cache

rm -rf ~/.repo-knowledge/<project-name>/

Step 3: Delete Cloned Repo (skip for personal knowledge bases)

Check ~/.repo-knowledge/<project-name>/_meta.md before deleting (read it first from Step 2's backup or skip if already deleted).

If type: personal or git_url: none: skip this step — there is no cloned repo.

Otherwise:

rm -rf ~/.repo-knowledge/_repos/<project-name>/

Step 4: Update Registry

Remove the project's row from ~/.repo-knowledge/_registry.md.

Step 5: Confirm

Tell the user: "Knowledge base for {project-name} has been deleted."

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.
