issue-writerDraft and revise concise, human-focused GitHub issues for pytest-kind-ng.
Issue Writer is an agent skill from NVIDIA/container-canary, published by the product's own GitHub organization. Draft and revise concise, human-focused GitHub issues for pytest-kind-ng. Use when asked to write, rewrite, review, or prepare a bug report, enhancement request, maintenance issue, or follow-up issue for this repository, including turning code-review findings into issues.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Testing & QA, covering Unit testing and QA and bug reports. It works with GitHub, pytest, Docker and Kubernetes. The repository describes itself as: A tool for testing and validating container requirements against versioned manifests. The licence is Apache-2.0.
6 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 425faeb. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
python3From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Issue Writer loads about 1.1k tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 587 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
The full file from NVIDIA/container-canary at commit 425faeb, republished under its Apache-2.0 licence (© NVIDIA). 587 words, ~1,103 tokens.
.claude/skills/issue-writer/SKILL.md (or your agent's skills folder).Write issues that let a maintainer understand the problem, reproduce it when applicable, and decide whether it matters without reading an implementation plan.
Prefer titles such as:
Port forwarding restarts after it becomes ready
Avoid solution-shaped titles such as:
Refactor port forwarding to use a new readiness mechanism
Make reproductions:
Prefer synthetic inline configuration or data over external repositories,
archives, logs, or private application data. Include only relevant environment
details, such as Python, pytest, kind, kubectl, OS, and architecture versions.
Use language-labelled fenced code blocks. Include the complete traceback or
command output when it is relevant; place unusually long output in a
<details> block rather than truncating the useful frames.
Present Python examples in python-labelled code blocks. Do not wrap Python
code in a shell heredoc such as python3 <<'PY' ... PY; readers can infer that
the example should be run with Python. Use a bash block only for shell
commands.
If a minimal reproduction is relevant but unavailable, state that limitation plainly instead of fabricating one.
Adapt the structure to the issue. Do not emit empty headings.
For a bug, usually include:
For an enhancement or maintenance issue, usually include:
Do not add a “Proposed solution” section, name files to edit, prescribe an architecture, or provide implementation steps. State the outcome that should be possible only when it is necessary to explain the problem.

Draft and revise concise, human-focused GitHub issues for pytest-kind-ng. Issue Writer is an agent skill from NVIDIA/container-canary, published by the product's own GitHub organization. Draft and revise concise, human-focused GitHub issues for pytest-kind-ng.
Issue Writer fits situations like: prepare a bug report; enhancement request; maintenance issue; follow-up issue for this repository.
Run `npx skills add NVIDIA/container-canary --skill issue-writer -a claude-code`. Or copy the skill folder (.agents/skills/issue-writer in NVIDIA/container-canary) into .claude/skills/issue-writer in your project. Claude Code loads it when a task matches its description.
Run `npx skills add NVIDIA/container-canary --skill issue-writer -a codex`. Or copy the skill folder (.agents/skills/issue-writer in NVIDIA/container-canary) into .agents/skills/issue-writer in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add NVIDIA/container-canary --skill issue-writer -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/issue-writer, .gemini/skills/issue-writer, .github/skills/issue-writer and .opencode/skills/issue-writer in your project.
Going by SKILL.md and its folder, Issue Writer needs the command-line tools its instructions call (python3). Our summary lists: Python 3.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Issue Writer is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.1k tokens (SKILL.md is roughly 4.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Issue Writer: NIC Testing Patterns (nginx/kubernetes-ingress, 5.1k stars), Weavebench Cua Reproduce (AMAP-ML/LongHorizon-Harness, 1.7k stars), Slow Tests (UKGovernmentBEIS/inspect_ai, 3k stars) and Robotics Testing (arpitg1304/robotics-agent-skills, 368 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
NVIDIA (a GitHub organization, an official publisher) maintains it in NVIDIA/container-canary, which has 309 GitHub stars. The repository was last updated on August 18, 2026.
