What is walkthrough-plugin CLAUDE.md?

Repository instructions for Walkthrough Plugin, an IntelliJ IDEA extension that displays guided, step-by-step help beside code lines. They cover the Kotlin project setup, building, running, testing and checks.

Use them when developing, building, running or checking the Walkthrough Plugin. They also explain that AGENTS.md should remain a symlink to CLAUDE.md.

They give an agent the project rules and commands needed to work on the extension consistently, including how to prepare the environment and verify changes.

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	$0.01625	$0.01625
Opus 5.5	$0.00650	$0.00650
Sonnet 5.5	$0.00325	$0.00325
Haiku 4.5	$0.00162	$0.00162

Security

Grade A, and why

walkthrough-plugin CLAUDE.md 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 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.
