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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00020 | $0.00275 |
| Opus 5 | $0.00010 | $0.00138 |
| Sonnet 5 | $0.00004 | $0.00055 |
| Haiku 4.5 | $0.00002 | $0.00028 |
Grade A, and why
eng-quality-handoff 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 10d 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
Collaborative Quality Handoff
Intent
- Make it effortless for reviewers, QA, and partners to understand, validate, and extend your work.
- Ensure ownership persists after merge via clear action items and shared context.
Workflow
- Narrate the change
- Summarize problem, approach, and tradeoffs in the PR/issue using concise bullets.
- Link related tickets, specs, dashboards, or smart-contract addresses.
- Surface review focus
- Call out risky areas, migrations, or TODOs explicitly; request specific expertise if needed.
- Attach evidence
- Provide test results, captures, or transaction hashes inline so reviewers don’t need to rerun everything.
- Plan follow-ups
- Create tasks for deferred work, debt, or experiment cleanups with owners and timelines.
- Stay available
- Monitor review threads, CI pipelines, and post-merge telemetry; respond quickly and document resolutions.
Verification
- Review checklist complete (tests attached, docs/flags updated, reviewers assigned).
- Outstanding issues tracked with owners; no “known issue” left implicit.
- After merge, confirm deployment/monitoring links are shared with relevant teams.
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.

eng-quality-handoff is a skill published in the GitHub repository tjboudreaux/cc-plugin-engineering-excellence (4 stars, last pushed 7mo ago), licensed MIT. It adds 20 tokens to every session and 275 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
