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 | $0.00045 | $0.00614 |
| Opus 5 | $0.00023 | $0.00307 |
| Sonnet 5 | $0.00009 | $0.00123 |
| Haiku 4.5 | $0.00005 | $0.00061 |
Grade A, and why
crossbeam-ops scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Fastest Path: Run a Full Test
# 1. Reset the demo project
curl -X POST https://cc-crossbeam.vercel.app/api/reset-project \
-H "Authorization: Bearer $CROSSBEAM_API_KEY" \
-H "Content-Type: application/json" \
-d '{"project_id":"b0000000-0000-0000-0000-000000000002"}'
# 2. Trigger corrections analysis
curl -X POST https://cc-crossbeam.vercel.app/api/generate \
-H "Authorization: Bearer $CROSSBEAM_API_KEY" \
-H "Content-Type: application/json" \
-d '{"project_id":"b0000000-0000-0000-0000-000000000002","flow_type":"corrections-analysis"}'
# 3. Poll until done (check project.status)
curl -s https://cc-crossbeam.vercel.app/api/projects/b0000000-0000-0000-0000-000000000002 \

What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

crossbeam-ops is a skill published in the GitHub repository mikeOnBreeze/cc-crossbeam (291 stars, last pushed 6mo ago), licensed MIT. It adds 45 tokens to every session and 614 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
