What is create-hotfix?

A workflow for creating a patch-release branch for an Azure SDK package written in Rust. A hotfix is a small release intended to correct an existing version.

Use it to prepare an Azure Rust crate hotfix, choose candidate commits, and cherry-pick them into the new branch.

It makes version discovery, branch creation, and optional selection of fixes from the main branch repeatable.

About the project

Azure SDK for Rust is a collection of Rust libraries, organized as separate crates, for interacting with Azure services. Rust developers use the crates and examples to build applications that work with Azure. The catalogue entries provide coding-agent skills, instructions, agents, and MCP integrations for working with the SDK.

Token cost

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	$0.00020	$0.00532
Opus 5	$0.00010	$0.00266
Sonnet 5	$0.00004	$0.00106
Haiku 4.5	$0.00002	$0.00053

Security

Grade A, and why

create-hotfix 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 2d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (create_hotfix.py, test_create_hotfix.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Create a Hotfix

Use the bundled script for deterministic discovery and git operations. Run all commands from the repository root.

List workspace crates:
```
python3 .github/skills/create-hotfix/create_hotfix.py list-crates
```
Use a single-select prompt to ask the user which crate to patch, using the crate names from the JSON output.
Prepare the hotfix:
```
python3 .github/skills/create-hotfix/create_hotfix.py prepare <crate-name>
```
The command fetches tags and main directly from https://github.com/Azure/azure-sdk-for-rust, finds the latest stable <crate-name>@<version> tag, calculates the next patch version, creates hotfix/<crate-name>-<version> from that tag unless already on a hotfix/ branch, and returns candidate commits from main as JSON.
If candidates were returned, prompt the user with a multiselect containing each candidate's SHA and deterministic summary. Allow selecting none.
If commits are selected, preserve their displayed order and run:
```
python3 .github/skills/create-hotfix/create_hotfix.py cherry-pick <sha>...
```
The script automatically resolves Cargo.lock conflicts by taking --ours, then regenerating it with:
```
cargo generate-lockfile --manifest-path Cargo.toml
```
If the JSON result has a waiting status, prompt the user to resolve and stage the listed conflicts. Remain waiting for the user to confirm they are ready, then run:
```
python3 .github/skills/create-hotfix/create_hotfix.py continue
```
Repeat this step if another commit conflicts. Do not abort or skip commits. Only show the final message after the script returns a complete status.
Report the selected crate, base tag, patch version, branch, and cherry-picked commits. Tell the user:

Make any additional hotfix changes on this branch. Do not merge this branch into main; cherry-pick any new fixes into main separately. See the Azure SDK hotfix branch policy for more information.

Files

What ships with it

2 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.

Changes

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.

create-hotfix is a skill published in the GitHub repository Azure/azure-sdk-for-rust (885 stars, last pushed yesterday), licensed MIT. It adds 20 tokens to every session and 532 once invoked, about $0.0001 per session on Opus 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 2026-09-03.
