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 | $0.00101 | $0.00407 |
| Opus 5 | $0.00051 | $0.00204 |
| Sonnet 5 | $0.00020 | $0.00081 |
| Haiku 4.5 | $0.00010 | $0.00041 |
Grade A, and why
cannibalization-check 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
Keyword Cannibalization Check
Identify queries where multiple pages on the same site are competing for rankings.
Steps
- Call
list_propertiesto confirm the exactsite_url. - Call
seo_cannibalizationto get a dedicated cannibalization report. This tool groups query+page combinations and surfaces the most severe conflicts directly, without manual filtering. - If
seo_cannibalizationreturns limited results, supplement withget_advanced_search_analyticsusingdimensions=query,page,sort_by=impressions,row_limit=1000. Group rows byquery: those with two or more distinct pages are candidates. - For each cannibalizing query, collect both page URLs with their individual clicks, impressions, CTR, and position.
- Sort candidates by total impressions (most valuable conflicts first).
- Limit the output to the top 20 most severe cases.
Output format
For each cannibalization case:
- Query: the competing keyword
- Pages: list each URL with its metrics (clicks / impressions / CTR / position)
- Severity: High / Medium / Low based on impressions at stake
- Recommendation: which page to consolidate to (pick the one with better position or CTR), and whether to use a canonical, redirect, or content merge
Present as a markdown table followed by a prioritized action list.
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.
