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 | $0.00057 | $0.01334 |
| Opus 5 | $0.00028 | $0.00667 |
| Sonnet 5 | $0.00011 | $0.00267 |
| Haiku 4.5 | $0.00006 | $0.00133 |
Grade A, and why
ad-campaign 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.
How it starts
The opening of the file, as written. The whole thing — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Ad creative sets
Ads fail on placement coverage and on having only one creative to test. Canvora
fixes both cheaply: every placement from one source in a single call, then
variants from the winner. Setup and credits: see the canvora skill.
Placement map
| Format | Size | Placement |
|---|---|---|
ad_square |
1:1 | feed (Meta, LinkedIn, the safe default) |
ad_portrait |
9:16 | stories, reels, vertical video slots |
ad_landscape |
16:9 1200×628 | link ads, in-stream, LinkedIn sponsored |
ad_banner |
21:9 728×90 | classic leaderboard display |
google_display |
1200×628 | Google Display Network |
Full coverage = ad_square,ad_portrait,ad_landscape — three placements,
30 credits, one consistent look. Add ad_banner/google_display only if they
actually run display.
Ads are 10 credits per creative. Say the total in the same message as the run —
announce it, don't ask permission; if you decided the number of angles yourself,
confirm that number. A campaign is several sequential calls, so sum the whole
plan and run canvora credits --json once before you start: running dry
halfway leaves a half-covered campaign with the earlier calls already paid for.
Any single call producing 3+ creatives should fire-and-poll rather than --wait
— most harnesses kill a shell command at 120s while the generation carries on
server-side, and re-running generate starts a second, separate job. See the
canvora skill's "Long runs" section.
Intake
- What's being advertised? A product URL is the best input — it carries the offer, the proof and the brand voice. Otherwise the offer in one line.
- Where does it run? Meta/IG → square + portrait. LinkedIn → square +
landscape. Google Display →
google_display+ad_banner. Unsure → the three-format set. - Brand kit —
--brand+--logo. Ads without the mark waste the spend. - The offer/CTA — "20% off first order", "Book a demo". Put it in the
brief and pass
--cta.
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.

ad-campaign is a skill published in the GitHub repository canvora/canvora-mcp (0 stars, last pushed 29d ago), licensed MIT. It adds 57 tokens to every session and 1,334 once invoked, about $0.0003 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.
