Antithesis Skills feedback

Skill version: 2026-09-23 a8fe900

Help the user file a bug report against the Antithesis skills by opening a pre-filled GitHub issue.

Base URL

https://github.com/antithesishq/antithesis-skills/issues/new?template=bug_report.yml

Pre-filling fields via URL parameters

GitHub issue templates accept query parameters to pre-fill fields. Each parameter key corresponds to the id of a field in the template. Append them as &<id>=<value> with values percent-encoded (spaces → %20, newlines → %0A, etc.).

The available fields are:

Parameter	Type	What to fill
`what-happened`	textarea	Brief summary of what went wrong. Keep to 1-2 sentences — the user will elaborate.
`expected`	textarea	Leave blank — only the user knows what they expected.
`skill`	input	The skill that was active (e.g. `antithesis-triage`, `antithesis-setup`).
`skill-version`	input	Run `git -C <skills-repo> rev-parse --short HEAD` to get the commit SHA.
`agent`	input	The agent name and version (e.g. `Claude Code 1.0.20`). Use the agent info available in your context.
`agent-explanation`	textarea	Your honest self-assessment: what did you do, and why did it go wrong? 2-4 sentences max.
`context`	textarea	Leave blank — the user can add screenshots and logs themselves.

You can also set the issue title via a title=<value> parameter.

How to construct the URL

Identify the skill that was being used when the problem occurred.
Get the skill version by running git rev-parse --short HEAD in the skills repo if you know where it is.
Determine agent info from your environment context (agent name + version).
Write a brief what-happened summary (1-2 sentences).
Write your agent-explanation — a short, honest self-assessment of what went wrong (2-4 sentences).
Set the title to a short description of the bug (under 80 characters).
Percent-encode all parameter values.
Assemble the URL by appending only the fields you can meaningfully fill. Do NOT fill expected or context — those are for the user.

URL length limit

Keep the total URL under 2000 characters. Browsers and GitHub may truncate or reject longer URLs. If the URL would exceed this limit:

Shorten what-happened and agent-explanation first — the user can edit these in the form.
Drop agent-explanation entirely if still too long.
As a last resort, drop what-happened too and only pre-fill skill, skill-version, agent, and title.

Presenting to the user

Do NOT auto-submit the issue. Open the URL (or print it if no browser is available) so the user can review the pre-filled fields, add their own details to expected and context, and submit when ready.
