dev-branch-deploy

dev-branch-deploy is a skill for Claude Code, Codex from notque/vexjoy-agent. It costs 76 tokens per session (1,990 once invoked), scanned A, original, MIT.

A workflow for deploying Hermes or Maia development branches to a live test environment before merging them into the main branch.

In plain words
What is it for?
Use it to configure the matching Concourse development lane, deploy a branch to a lab region, and validate the stack before merging.
Why use it?
It lets teams test chart or secret changes in a lab without merging to the main branch or risking production.

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

dev-branch-deploy 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.

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.

Dev-Branch Deploy — Hermes & Maia

Test a Hermes or Maia stack change in a live lab region before merging to master, using the pipeline's parallel dev lane. One workflow, two stacks — parametrized by stack.

The problem this solves

Concourse pins a git branch: per resource at pipeline-definition time; you can't override it at trigger time. So normally you must merge to master to see a chart/secrets change run in a lab. The dev lane adds a second set of jobs pointed at <stack>-dev-branch, so you deploy and validate in a real lab region with no risk to master or production.

Stack parameters

Everything below is identical between stacks except these values.

Param hermes maia
Dev branch hermes-dev-branch maia-dev-branch
fly target ci-monitoring monitoring
Concourse https://ci1.eu-de-2.cloud.sap https://ci.eu-de-2.cloud.sap
Pipeline dir ci/hermes/ in cc/secrets ci/maia/ in cc/secrets
set-pipeline vars --load-vars-from vars.yaml
Chart openstack/hermes openstack/maia

Constants (both stacks):

  • Team: monitoring
  • Lab regions the dev lane deploys to: qa-de-1, qa-de-2, qa-de-3, eu-de-3
  • Repos the dev branch must exist on: cc/secrets (GHE github.wdf.sap.corp) and sapcc/helm-charts (github.com)
  • Local cc/secrets clone: ~/gh/secrets

The two lanes

Lane Branch Role
labs master Guards production-branch health. Never break it.
dev <stack>-dev-branch Sandbox: validate a feature in a real lab before master.

Both deploy to the same lab regions, independently. Production lanes (bronze/silver/gold/global) are untouched by this workflow.

Pipeline wiring (reference)

Dev lane = paired git resources + a dev job group.

  • secrets-dev.git<stack>-dev-branch (twin of secrets.git on master)
  • helm-charts-dev.git<stack>-dev-branch (twin of helm-charts.git on master)
  • Shared by both lanes: built image, kube-secrets, credentials.

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.
