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 | $0.00038 | $0.02290 |
| Opus 5 | $0.00019 | $0.01145 |
| Sonnet 5 | $0.00008 | $0.00458 |
| Haiku 4.5 | $0.00004 | $0.00229 |
Grade A, and why
cloudformation-to-pulumi 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 11d 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.
This is a copy
91% identical to cloudformation-to-pulumi — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

IMPORTANT: PLAN ADJUSTMENT REQUIRED
If you have already generated a migration plan before loading this skill, you MUST:
- Review your existing plan against the workflows and requirements in this skill
- Identify any gaps, missing steps, or incorrect assumptions
- Update and revise your plan to align with this skill's guidance
- Communicate the adjusted plan to the user before proceeding
CRITICAL SUCCESS REQUIREMENTS
The migration output MUST meet all of the following:
-
Complete Resource Coverage
- Every CloudFormation resource MUST be represented in the Pulumi program OR explicitly justified in the final report.
-
CloudFormation Logical ID as Resource Name
- CRITICAL: Every Pulumi resource MUST use the CloudFormation Logical ID as its resource name.
- This enables the
cdk-importertool to automatically find import IDs. - DO NOT rename resources. Automated import will FAIL if you change the logical IDs.
-
Successful Deployment
- The produced Pulumi program must be structurally valid and capable of a successful
pulumi preview(assuming proper config).
- The produced Pulumi program must be structurally valid and capable of a successful
-
Zero-Diff Import Validation (if importing existing resources)
- After import,
pulumi previewmust show NO updates, replaces, creates, or deletes.
- After import,
-
Final Migration Report
- Always output a formal migration report suitable for a Pull Request.
WHEN INFORMATION IS MISSING
If the user has not provided a CloudFormation template, you MUST fetch it from AWS using the stack name.
MIGRATION WORKFLOW
Follow this workflow exactly and in this order:
1. INFORMATION GATHERING
1.1 Verify AWS Credentials (ESC)
Running AWS commands requires credentials loaded via Pulumi ESC.
- If the user has already provided an ESC environment, use it.
- If no ESC environment is specified, ask the user which ESC environment to use before proceeding.
For detailed ESC information: Use skill pulumi-esc.
You MUST confirm the AWS region with the user.
What ships with it
3 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.

cloudformation-to-pulumi is a skill published in the GitHub repository dirien/yet-another-agent-harness (20 stars, last pushed 3mo ago), licensed MIT. It adds 38 tokens to every session and 2,290 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 91% identical to cloudformation-to-pulumi, differing in 2 lines, and is treated as a copy.
