kube-coder: Skill for Claude Code

.claude/skills/kc-issue/SKILL.md

kc-issue is a skill for Claude Code from imran31415/kube-coder. It costs 115 tokens per session (2,083 once invoked), scanned A, original, MIT.

An issue-work setup for kube-coder that creates an isolated Git worktree from the latest main branch and starts a background coding agent inside it. A worktree is a separate working copy of a Git repository.

In plain words
What is it for?
Use it to start work on a numbered kube-coder issue, list existing issue worktrees and task status, and optionally prepare a pull request when the work is complete.
Why use it?
It keeps each issue’s files and changes separate, reducing the chance that one agent interferes with another task.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

This is imran31415/kube-coder's own configuration. It tells Claude Code how to work on kube-coder itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything kube-coder configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /home/dev/kube-coder.

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.

Security

Grade A, and why

kc-issue 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 1mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (kc-issue.sh, lint_test.sh), 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.

How it starts

The opening of the file, as written. The whole thing — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.

kc-issue — one issue, one clean worktree, one agent

This is the reliable entrypoint for per-issue work — on kube-coder or any other repository checked out in the workspace. It removes the two things that made ad-hoc worktree use flaky:

  1. It branches from a freshly-fetched origin/<default branch>, never a stale local HEAD.
  2. The agent is launched inside its own worktree, so it starts inside its isolation and physically cannot forget to use it.

Which repository: the git checkout you run the script from (any folder in it, or one of its worktrees), or KC_REPO_ROOT=/home/dev/<repo>; the GitHub repo is read from its origin remote (KC_REPO_SLUG=owner/repo overrides). From /home/dev itself it falls back to /home/dev/kube-coder.

The heavy lifting is in kc-issue.sh next to this file. It does the git/fs part and prints JSON; you (the assistant) do the launch via create_task.

Do this when invoked

list — show existing issue worktrees + task status

bash "$CLAUDE_SKILL_DIR/kc-issue.sh" list

Then call mcp__dashboard__list_tasks and correlate by worktree/branch so the user sees which issues have a live agent.

<issue-number> (optionally --pr) — start an agent on an issue

Step 1 — create/reuse the worktree and get the prompt. If the user passed --pr (auto-open a PR when done), set KC_AUTO_PR=1:

# without --pr (default: preflight then STOP for review):
bash "$CLAUDE_SKILL_DIR/kc-issue.sh" <N>
# with --pr (preflight, push, open PR):
KC_AUTO_PR=1 bash "$CLAUDE_SKILL_DIR/kc-issue.sh" <N>

Capture the JSON it prints on stdout: {issue,title,url,worktree,branch,port,prompt_file,auto_pr,mode,repo_root,repo,slug,base_ref,lint,lint_blockers}.

mode says who makes the worktree:

  • server — this workspace's dashboard creates it when the Build launches (#701), so the Build is recorded with it: its Changes tab shows the diff and push command, and Settings → Worktrees lists it. worktree is where it will be; port is empty until launch.
  • script — an older workspace: the script created the worktree itself.

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.
