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 | $0.00035 | $0.00566 |
| Opus 5.5 | $0.00014 | $0.00226 |
| Sonnet 5.5 | $0.00007 | $0.00113 |
| Haiku 4.5 | $0.00003 | $0.00057 |
Grade A, and why
cc-cursor-cc 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.
What it actually says
CC-Cursor-CC Skill (Plan Validation Round Trip)
Supports the flow of sending brainstormed content from Claude Code to Cursor (PM) for feasibility validation.
Prerequisites
This skill assumes 2-agent operation.
| Role | Agent | Description |
|---|---|---|
| PM | Cursor | Validate plans, update Plans.md |
| Impl | Claude Code | Brainstorming, implementation |
Execution Flow
Step 1: Extract Brainstorming Context
Extract from recent conversation:
- Goal (feature/purpose)
- Technology choices
- Decisions made
- Undecided items
- Concerns
Step 2: Add Provisional Tasks to Plans.md
## 🟠 Under Validation: {{Project}} `pm:awaiting-validation`
### Provisional Tasks (To Validate)
- [ ] {{task1}} `awaiting-validation`
- [ ] {{task2}} `awaiting-validation`
### Undecided Items
- {{item1}} → **Requesting PM decision**
Step 3: Generate Validation Request for Cursor
Generate text to copy-paste to Cursor:
## 📋 Plan Validation Request
**Goal**: {{summary}}
**Provisional tasks**:
1. {{task1}}
2. {{task2}}
### ✅ Requesting Cursor (PM) to:
1. Validate feasibility
2. Break down tasks
3. Decide undecided items
4. Update Plans.md (awaiting → cc:TODO)
Step 4: Guide Next Action
- Copy & paste request to Cursor
- Run
/plan-with-ccin Cursor - Cursor updates Plans.md
- Cursor runs
/handoff-to-claude - Copy & paste back to Claude Code
Overall Flow
Claude Code (Brainstorm)
↓ /cc-cursor-cc
Cursor (PM validates & breaks down)
↓ /handoff-to-claude
Claude Code (/work implements)
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.
- 1mo ago First seen · 84 lines · 35 tokens per session scan A 1ddc66401382
cc-cursor-cc is a skill published in the GitHub repository Chachamaru127/codex-harness (2 stars, last pushed 8mo ago), licensed MIT. It adds 35 tokens to every session and 566 once invoked, about $0.0001 per session on Opus 5.5. 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.
