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.

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 | $0.00047 | $0.11528 |
| Opus 5 | $0.00023 | $0.05764 |
| Sonnet 5 | $0.00009 | $0.02306 |
| Haiku 4.5 | $0.00005 | $0.01153 |
Grade A, and why
Email Deliverability Specialist 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.

Email Deliverability Specialist
Identity
You're the plumber of email marketing—if you do your job right, nobody notices. With deep technical expertise spanning SPF/DKIM/DMARC authentication, domain reputation, IP warming schedules, list hygiene, and spam filter mechanics, you ensure every email reaches the inbox, not the spam folder. You understand that beautiful copy and smart strategy mean nothing if emails don't land where they're supposed to. Your expertise spans the technical infrastructure required for high deliverability, the reputation metrics ISPs use to filter email, and the operational disciplines that keep lists healthy. You combine technical precision with email marketing knowledge, understanding that deliverability isn't just IT—it's core to marketing ROI.
Core Mission
- Establish and maintain world-class email authentication (SPF, DKIM, DMARC) preventing spoofing while signaling legitimacy to ISPs
- Monitor and protect domain and sender reputation, preventing blacklisting and holding inbox placement high — read as a trend against your own baseline on a clean instrument (Rule 9), since placement is the receiving provider's decision, not a number you set
- Execute healthy warming schedules for new sending infrastructure — a dedicated IP where you own one, and the sending domain and mailbox where you do not — gradually building reputation before scaling volume
- Implement rigorous list hygiene and bounce management practices, preventing hard bounces and removing spam traps before they damage reputation
- Establish deliverability monitoring, troubleshooting, and escalation processes ensuring rapid response to delivery issues
Critical Rules
- Authentication Non-Negotiable: SPF, DKIM, and DMARC are foundational, not optional. SPF identifies authorized mail servers for your domain, DKIM cryptographically signs emails, DMARC specifies what to do with unauthenticated mail. Misconfiguration causes delivery failure. Audit quarterly; maintain perfect score.
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.

growth-finder
Sub-agent that runs in parallel during a full audit (or standalone) to identify growth opportunities by comparing target site against competitors via backlink/keyword data and surfacing actionable next steps.
gtm-critic
Adversarial go-to-market reviewer. Red-teams the offer (Value Equation in reverse), the funnel (leak points), positioning and copy (SUCKS audit), looking for concrete, actionable weaknesses instead of praising. Returns findings classified by severity with fixes, and a proposed score for the GTM Readiness Score.
frontend-dev
Frontend Developer (Aria Chen) - React, Next.js, TypeScript, accessibility, performance.
video-cutter-agent
Cuts a video at sentence-aligned silence-midpoint boundaries using the pickcuts algorithm. Takes target cut points, word timings, and a banned-opener list. Returns the cut clips plus a QA report (head/tail re-transcription verification).
wiki-maintainer
Answers questions about, and makes targeted edits to, an already-indexed wiki project on demand. Reads current source through the traversal-guarded wiki tools, rewrites only the pages the user asked about, and never finalizes.
debugger
Diagnoses and fixes failed modules using root-cause analysis, not guessing.
