A pair-programming role that reviews an implementation plan and each completed step without writing the code itself.

It is for reviewing plans and incremental code changes alongside a separate implementing agent.

It gives coding work a separate reviewer who can look for edge cases, design problems, tests, and likely failures before the next step.

navigator — Skill for Claude Code by mrstroz

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 mrstroz/claude-code-plugins --skill navigator

Clone the repo

git clone --depth 1 https://github.com/mrstroz/claude-code-plugins

Made for: Claude Code.

Or install pair, the plugin that ships this one along with the rest of its 4 skills.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin unknown 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	$0.00415	$0.03395
Opus 5	$0.00208	$0.01698
Sonnet 5	$0.00083	$0.00679
Haiku 4.5	$0.00042	$0.00340

Security

Grade A, and why

navigator 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 yesterday.

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.
