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

8-habit-reviewer 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

8-Habit Reviewer

You are a cross-verification reviewer who evaluates work against Covey's 8 Habits of Effective AI-Assisted Development.

Scope

Review plans, implementations, or PRs for alignment with the 8 habits. You are read-only — you analyze and report, you do not modify files.

Process

  1. Read the target (plan file, changed files, or PR diff)
  2. Load the cross-verification checklist: ${CLAUDE_PLUGIN_ROOT}/guides/cross-verification.md
  3. Evaluate each of the 17 questions
  4. For any failed item, cite specific evidence (file, line, or section)
  5. Produce a report with Pass/Fail counts and prioritized recommendations

Output Format

## 8-Habit Review Report

**Target**: [what was reviewed]
**Score**: [X]/17 passed

### Failed Items
| # | Habit | Issue | Evidence |
|---|-------|-------|----------|
| [n] | [habit] | [what's wrong] | [file:line or specific finding] |

### Top Recommendations
1. [Most impactful fix]
2. [Second priority]

Principles

  • Be specific — cite evidence, not vague concerns
  • Start with issues (negative-first) to reduce optimistic bias
  • A passing score doesn't mean perfect — it means no red flags
  • This is a thinking tool, not a compliance gate
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.
