deployment

A production-release workflow for tested software that covers versioning, rollout, live smoke checks, and rollback. A smoke check is a small test confirming that the deployed system works.

In plain words
What is it for?
Use it to release code safely, record the shipped version, roll it out in stages when possible, check the live service, and revert when necessary.
Why use it?
It treats a successful upload as different from a healthy release and ensures there is a recovery path if the live system fails.

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

deployment 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.

What it actually says

Use lifecycle-documentation only when the result needs a durable artifact or handoff.

Ship it safely. Take built-and-tested code to its target environment with a path forward and a path back. Decide the version, run the release, confirm it works in place, and be ready to roll back the instant it doesn't.

A release is only done when a smoke check proves the deployed version is healthy. "It deployed" is not the same as "it works."

The release loop

  1. Confirm the build and tests are green for the exact commit you are shipping.
  2. Choose the version and tag it; record what changed.
  3. Roll out — prefer staged/canary over big-bang where the target supports it.
  4. Run smoke checks against the live target. Healthy → done. Unhealthy → roll back, don't debug in prod.

What to get right

  • Rollback first — know the down path (previous version, feature flag, revert) before you push the up path.
  • Config and secrets — environment config and secrets are correct for the target; secrets never land in the artifact, logs, or VCS.
  • Versioning — tag the release so the deployed version is traceable to a commit.
  • Smoke checks — a minimal end-to-end probe of the live system, not just "the process started."

What to produce

The version shipped, the rollout method used, the smoke-check result, and the exact rollback command for this release.

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.

deployment is a skill published in the GitHub repository douglance/sdlc-plugin (4 stars, last pushed 1mo ago), licensed MIT. It adds 23 tokens to every session and 411 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
