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.

What it costs to keep this loaded
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 | $0.00021 | $0.02439 |
| Opus 5 | $0.00010 | $0.01220 |
| Sonnet 5 | $0.00004 | $0.00488 |
| Haiku 4.5 | $0.00002 | $0.00244 |
Grade A, and why
vllm-compare-reqs 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 8d 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.

vllm Compare Requirements Skill
Purpose
Compare vllm requirements files and Dockerfiles between versions to identify dependency changes, providing intelligent analysis for AIPCC package onboarding workflows.
For accelerator builds (ROCm, CUDA, TPU, XPU), Dockerfile comparison is critical because they specify exact commits/branches for dependencies built from source (PyTorch, Triton, Flash Attention, etc.) - information not available in requirements files.
Note: Starting from v0.20, vllm moved build requirements into a build/ subdirectory (e.g., build/rocm.txt instead of rocm-build.txt). The script automatically handles both layouts, falling back to the old paths for older versions. This makes cross-version comparisons (e.g., v0.19 vs v0.20) work seamlessly.
Skill Type
Executable Script - Runs a Python script to fetch and compare requirements files from the vllm GitHub repository.
When to Use
Use this skill when you need to:
- Compare vllm runtime AND build requirements between versions before upgrading
- Identify new packages that need onboarding to the AIPCC wheels builder
- Understand dependency changes for specific hardware variants (ROCm, CUDA, etc.)
- Analyze Dockerfile ARG changes (build commits/branches for ROCm/CUDA)
- Debug build failures related to dependency mismatches
Note: Variant comparisons include BOTH runtime and build dependencies to ensure complete coverage.
Usage
Basic Syntax
./scripts/compare_reqs.py <version1> <version2> <variant|file> [--pretty]
Arguments
- version1: First version to compare (e.g.,
v0.13.0,v0.14.0rc1) - version2: Second version to compare
- variant|file: Either:
- Variant name:
rocm,cuda,cpu,tpu,xpu(auto-includes runtime + build requirements + Dockerfiles) - Specific file:
build/rocm.txt,common.txt,docker/Dockerfile.rocm, etc. (old-style paths likerocm-build.txtalso accepted)
- Variant name:
- --pretty: Show clean categorized output (default)
- --no-pretty: Show simple diff output
What ships with it
1 file 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.

vllm-compare-reqs is a skill published in the GitHub repository opendatahub-io/ai-helpers (37 stars, last pushed 4d ago), licensed Apache-2.0. It adds 21 tokens to every session and 2,439 once invoked, about $0.0001 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 2026-09-03.
