What it does
Kc Entrypoint Change is an agent skill from imran31415/kube-coder. Safely edit the workspace pod's boot scripts (start.sh, the entrypoint/ssh-server configmaps) in kube-coder. Use when changing anything that runs at pod start — credential wiring, service launch, tmux/ttyd config, symlinks — where the two-home layout and Helm templating have non-obvious footguns.
Its SKILL.md is about 1.3k 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 DevOps & Cloud, covering Container orchestration. It works with tmux. The repository describes itself as: helm chart for a isolated dev coding environment pod in kubernetes. The licence is MIT.

Requirements
- Pre-approved tools (allowed-tools): Bash, Read, Edit, Grep
What it can do on your machine
Read from SKILL.md and the folder at commit fc0b886. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
BashReadEditGrep
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
helmbash
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use helm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Kc Entrypoint Change loads about 1.3k tokens when it runs. Until then it costs about 80 tokens; SKILL.md has 464 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.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.

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.

Editing kube-coder boot scripts safely
Changes to the pod entrypoint affect every workspace on next restart, and a mistake can break boot for everyone. This skill captures the gotchas and the validation loop.
Where boot logic lives
charts/workspace/start.sh— the main IDE container entrypoint. Shipped into a ConfigMap via{{ tpl (.Files.Get "start.sh") . | indent 4 }}intemplates/workspace-entrypoint-configmap.yaml, and run ascommand: ["/bin/bash","-l","/workspace-entrypoint/start.sh"].charts/workspace/templates/ssh-server-configmap.yaml— the SSH sidecar entrypoint (data.entrypoint.sh), gated by{{- if .Values.ssh.enabled }}.charts/workspace/templates/terminal-entry-configmap.yaml— the per-ttyd connection script (tmux attach / DEC-mode resets).
Prefer editing start.sh as a real file; the configmaps are YAML block scalars.
Footgun 1 — the two-home layout (MOST IMPORTANT)
There are two home directories:
/home/dev— the persistent PVC. Survives restarts./home/ubuntu— ephemeral. Wiped on every pod restart.
start.sh and the interactive terminals (ttyd, code-server, SSH) run with
HOME=/home/ubuntu. That's why /home/ubuntu/.ssh is a symlink but
/home/dev/.ssh doesn't exist. Anything a tool writes under $HOME is lost
on restart unless it's redirected onto /home/dev.
The established pattern to persist something is: keep the real data under
/home/dev/... (secrets go in /home/dev/.credentials/), and symlink the
ephemeral $HOME path to it. See the persist_cred helper and the
for HOME_DIR in /home/ubuntu loops in start.sh, and the mirrored block in
ssh-server-configmap.yaml (the sidecar has its own ephemeral
/home/ubuntu, so it needs the symlinks independently).
When persisting a new credential/config: migrate any pre-existing login onto the
PVC once with cp -an (archive + no-clobber, so a real PVC login is never
overwritten by a stale ephemeral copy), then replace with a symlink. Make it
idempotent — guard with [ -L "$link" ] so re-runs don't nest symlinks.

Footgun 2 — tpl runs Go templating over start.sh
Because the configmap uses {{ tpl (.Files.Get "start.sh") . }}, any literal
{{ ... }} in start.sh is interpreted by Helm. Plain shell ($VAR,
$(cmd), backticks) is fine, but never introduce {{/}} unless you mean
a template action. After editing, always render (below) to catch this.
Footgun 3 — configmap YAML indentation
The sidecar script is a data.entrypoint.sh: | block scalar at 4-space indent.
Keep added lines at the same indent; a stray dedent silently truncates the
script. helm template will surface most of these.
Footgun 4 — two ttyd launch sites
start.sh launches ttyd once at boot and relaunches it in the watchdog
loop. If you change ttyd flags, change both occurrences (grep for ttyd).
Footgun 5 — overwrite-on-boot files
CLAUDE.md/claude-md.txt, ~/.tmux.conf, and the OpenCode config are
rewritten every boot so chart edits propagate. Don't add logic that
"preserves existing" for these — it defeats the design. User notes belong in the
persistent-memory subsystem, not these files.
Validation loop (always run before pushing)
# 1. Shell syntax — a broken start.sh breaks boot for every workspace.
bash -n charts/workspace/start.sh
# 2. Render through Helm (catches tpl + YAML indent errors, proves it ships).
export PATH="$HOME/.local/bin:$PATH"
helm template test-ws charts/workspace/ -f charts/workspace/tests/test-values.yaml >/tmp/r.yaml
grep -n "<a string from your change>" /tmp/r.yaml # confirm it rendered
# sidecar is gated — render it with ssh on:
helm template test-ws charts/workspace/ -f charts/workspace/tests/test-values.yaml \
--set ssh.enabled=true >/tmp/r-ssh.yaml
# 3. If you can, unit-execute the logic in a sandbox against fake /home dirs
# (extract the function, rebind paths to /tmp, stub chown) to prove
# fresh / migrate / no-clobber / idempotent behavior.Add a regression test
Boot-script behavior is covered by helm-unittest files in
charts/workspace/tests/*_test.yaml. Add matchRegex assertions on
data["start.sh"] (and data["entrypoint.sh"] for the sidecar, with
set: {ssh.enabled: true}) so your change can't silently regress. Model it on
credential_persist_test.yaml or browser_gate_test.yaml. Then:
helm unittest charts/workspace/Finish by running kc-preflight, then kc-ship-pr.
