Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00041 | $0.00370 |
| Opus 5 | $0.00020 | $0.00185 |
| Sonnet 5 | $0.00008 | $0.00074 |
| Haiku 4.5 | $0.00004 | $0.00037 |
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
- Read the target (plan file, changed files, or PR diff)
- Load the cross-verification checklist:
${CLAUDE_PLUGIN_ROOT}/guides/cross-verification.md - Evaluate each of the 17 questions
- For any failed item, cite specific evidence (file, line, or section)
- 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
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.

8-habit-reviewer is an agent published in the GitHub repository pitimon/8-habit-ai-dev (3 stars, last pushed today), licensed MIT.

reviewer
Use this agent when performing code review, verifying spec compliance, conducting quality review after a build, or checking that an implementation matches its plan. Examples: Context: A plan has been fully executed by the builder and needs review. user: "Review the authentication implementation" assistant: "I'll…
code-reviewer
The pipeline's post-implementation review-and-fix pass — reviews the diff a task's implementation just produced, proves each candidate defect before touching it, fixes the confirmed ones inside the plan's Touches, runs the project's own build and tests, and commits its fixes on top.
