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

review-plan-with-claude 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 12d 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

Review a Codex plan with Claude

Use the most recent complete development plan visible in the conversation. If there is no complete plan, ask the user for it instead of inventing missing steps.

Call only mcp__inspectrum__review_plan, once, with:

plan: <the full plan in Markdown>
reviewers: ["claude"]
focus: all
judge: false

Keep an explicitly requested focus (correctness, completeness, risk, or clarity) instead of all. Do not add another reviewer, invoke a judge, call a second tool, or substitute Codex's own analysis for Claude's review.

Successful result

Treat the review as successful only when the tool response does not have isError: true and includes structuredContent with verdict and report_markdown.

Render report_markdown, identify the verdict as Claude's review, and include the session path. If a revised_plan is present, offer it to the user without executing it or silently replacing the original plan.

Claude or tool unavailable

If the call fails, returns isError: true, or has no valid structuredContent, say:

The Claude review did not complete.

Show the concise, non-sensitive error text when available. Suggest checking claude --version, completing Claude's interactive authentication, and then retrying the review. Never present this failure as approve, as a successful review, or as an opinion actually produced by Claude.

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.
