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 | $0.00073 | $0.03279 |
| Opus 5.5 | $0.00029 | $0.01312 |
| Sonnet 5.5 | $0.00015 | $0.00656 |
| Haiku 4.5 | $0.00007 | $0.00328 |
Grade A, and why
meta-ads-manager 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 369 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Meta Ads Manager
This skill handles end-to-end Meta advertising — from campaign strategy and creation to optimization and reporting across Facebook and Instagram.
When to Use This Skill
- Creating new ad campaigns (Facebook or Instagram)
- Writing ad copy and headlines
- Defining audience targeting (custom, lookalike, interest-based)
- Setting and managing ad budgets
- Analyzing campaign performance (ROAS, CPA, CTR)
- A/B testing ad variations
- Optimizing underperforming campaigns
- Creating retargeting campaigns
- Scaling winning ads
- Generating performance reports
Campaign Architecture
Meta Ads Structure
Account
└── Campaign (objective: what you want)
└── Ad Set (audience + budget + placement + schedule)
└── Ad (creative + copy + CTA)
Campaign Objectives (choose one per campaign)
| Objective | Use When | Key Metric |
|---|---|---|
| Awareness | Brand building, reach | CPM, Reach |
| Traffic | Drive website visits | CPC, CTR |
| Engagement | Post likes, comments, shares | CPE, Engagement Rate |
| Leads | Collect emails/phone via form | CPL, Lead Volume |
| App Promotion | Drive app installs | CPI, Install Volume |
| Sales | E-commerce conversions | ROAS, CPA, Conversion Rate |
Budget Strategy
Daily vs. Lifetime Budget:
- Daily budget: Best for always-on campaigns. Meta spends roughly this amount each day.
- Lifetime budget: Best for time-limited promotions. Meta optimizes spend across the full period.
Budget Guidelines:
- Minimum: $5/day per ad set (Meta's minimum)
- Testing: $20-50/day per ad set to exit learning phase quickly
- Learning phase: ~50 conversions per ad set per week needed
- Scale: Increase budget by max 20% every 3 days (avoid resetting learning)
Advantage Campaign Budget (CBO):
- Let Meta distribute budget across ad sets automatically
- Best when you have 3+ ad sets and want Meta to find the best one
- Set minimum/maximum spend per ad set if needed
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.

meta-ads-manager is a skill published in the GitHub repository djbelieny/nova (5 stars, last pushed 3mo ago), licensed MIT.

commonly
You are a member of a Commonly workspace — a shared space where humans and AI agents from any origin collaborate in pods (chat rooms with memory). Use this whenever you are connected to Commonly via the commonly MCP tools: to read what's happening, post, remember things across sessions, react, DM other agents, and…
officecli-commonly-templates
Use this skill when producing a polished, Commonly-branded deliverable (.docx brief / memo, .xlsx data matrix, .pptx deck) and you do not have specific brand guidance from the user. Trigger on: 'write me a brief', 'one-pager', 'memo', 'data sheet', 'status matrix', 'short deck', 'summary deck', 'closing slide', 'final…
pod-chat-tone
In-product voice rewrite for agents posting to Commonly pods — kills the report-in-a-chatbox shape (bold-lead sentences, ✅/❌ ladders, em-dash density, mirror clauses, self-narration of one's own reasoning) that makes agent rooms unreadable to the humans they are for. Mandatory pre-post pass on every pod message.…
testing
Testing and code quality context for Jest, React Testing Library, ESLint, and test patterns. Use when writing tests or fixing linting issues.
github
Interact with GitHub (issues, PRs, repos, releases) using the gh CLI. Use when asked to read or write GitHub state — open an issue, fetch PR diff, comment, list runs, etc.

Convert binary documents (PDF, DOCX, XLSX, PPTX, HTML, EPUB, images) to clean LLM-friendly Markdown using Microsoft's markitdown Python tool. Use when a user attaches a binary file and you need to read its contents.
