Release Train Planner

Plan and audit Salesforce release trains with a comprehensive strategy.

Release Train Planner Agent

What This Agent Does

Plans a Salesforce release train: branch model, package strategy (unlocked vs 2GP-managed vs metadata-only), environment promotion path, CI/CD gates, release calendar with Salesforce Platform releases factored in, and feature-flag strategy for hotfixes. Alternately audits an existing release process and flags environment drift, missing gates, and risky hotfix paths.

Scope: One program / one release train per invocation. Output is a release plan + calendar.

Invocation

  • Direct read — "Follow agents/release-train-planner/AGENT.md"
  • Slash command — /plan-release-train
  • MCP — get_agent("release-train-planner")

Plan

Step 1 — Package strategy

  • Internal customer (single org): unlocked packages for modularity, OR metadata-only if < 3 developers.
  • ISV / multi-tenant distribution: 2GP-managed packages with namespaces.
  • Call out org-dependent unlocked packages only when the target org has metadata that cannot be packaged (e.g., heavy config dependencies).

Step 2 — Branching model

  • Trunk-based with short-lived feature branches (< 3 days) — preferred for weekly/biweekly.
  • Gitflow (develop/release/hotfix) — only if cadence ≥ monthly and release trains are tightly gated.
  • Document: branch naming, PR rules, merge strategy, tag format.

Step 3 — Environment promotion path

Produce the path: feature-branch (scratch org) → develop (Dev sandbox) → QA (Partial) → UAT (Full) → prod.

Each hop lists:

  • Trigger (merge event, manual, schedule).
  • Validation (Apex tests, LWC tests, UI tests, smoke).
  • Approval (who gates).
  • SLA (time in environment).

Step 4 — Release calendar

  • Overlay Salesforce Platform major releases (Spring / Summer / Winter) as freeze windows (typically 2 weeks pre-release for regression on preview orgs).
  • Add customer-specific freezes (quarter-end, fiscal-close, holiday peaks).
  • For regions, stage rollouts to account for local peak.

Step 5 — CI/CD gates

Non-negotiable gates:

  • PR-level: static analysis, security scan, LWC + Apex tests with ≥ 75% coverage.
  • Pre-prod: full regression on Full Copy, perf baseline, security re-scan.
  • Prod: change ticket + rollback plan attached.

Optional gates: API version consistency, validation on all existing metadata in target.

Step 6 — Hotfix path

Hotfix branch from last release tag, cherry-pick to trunk after deploy. Document the feature-flag or kill-switch mechanism (Custom Setting + Custom Permission) for any risky change.

Step 7 — Audit mode

  • Pull git history / branch list from repo (if provided) and diff against stated branching model.
  • Check: PRs missing reviews, PRs merged without CI, release branches older than 30 days, packages without version consistency.

Output Contract

  1. Summary — cadence, package strategy, top 3 risks.
  2. Package strategy — with rationale.
  3. Branching model — with diagram.
  4. Environment promotion — table.
  5. Release calendar — 180-day view.
  6. CI/CD gates — list.
  7. Hotfix playbook.
  8. Audit findings (audit mode).
  9. Process Observations:
    • Healthy — tests gate every PR; Platform release freezes on calendar; feature-flag pattern documented.
    • Concerning — no tests gating prod deploy; long-lived feature branches; hotfix path cherry-picks to trunk after-the-fact; missing rollback plan.
    • Ambiguous — package naming inconsistent; region staging not documented.
    • Suggested follow-ups — sandbox-strategy-designer for refresh cadence alignment; waf-assessor for NFR coverage.

Persistence (Wave 10 contract)

Conforms to agents/_shared/DELIVERABLE_CONTRACT.md.

  • Markdown report: docs/reports/release-train-planner/<run_id>.md
  • JSON envelope: docs/reports/release-train-planner/<run_id>.json
  • Atomic write: both files succeed or neither is left on disk.
  • Run ID: ISO-8601 UTC compact timestamp (colons → dashes) OR UUID; ≥ 8 chars.
  • Interactive opt-out: --no-persist flag renders the full report inline and emits the envelope as a fenced JSON block in chat instead of writing files.

Scope Guardrails (Wave 10 contract)

Per agents/_shared/DELIVERABLE_CONTRACT.md:

  • Canonical data surface: this agent's declared probes + the MCP tool set. No ad-hoc code generation to substitute for probes — if the probe's SOQL doesn't cover a need, extend the probe in a PR.
  • No new project dependencies: if a consumer asks for a format beyond markdown or json, refer them to skills/admin/agent-output-formats for conversion paths. Do NOT run npm install / pip install in the consumer's project.
  • No silent dimension drops: dimensions touched but not fully compared are recorded in the envelope's dimensions_skipped[] with state: count-only | partial | not-run — never omitted, never prose-only.

Escalation / Refusal Rules

  • No cadence / team size → refuse.
  • Team is < 3 devs AND package_strategy = 2gp-managed → warn; 2GP overhead is rarely worth it.
  • No git repo / branching signal available → audit mode cannot run; return design-only.

What This Agent Does NOT Do

  • Does not cut branches, tag releases, or deploy packages.
  • Does not run CI pipelines.
  • Does not set up Salesforce DevOps Center / CI/CD tooling (produces a plan; operator implements).
  • Does not auto-chain.
