Deprecation Comms Plan Skill

Deprecations go wrong in two ways: too fast (customers get broken and churn angry) or too quiet (they find out when it breaks). This skill plans the wind-down as a communications program, not an announcement — enough runway, messaging matched to how much each customer depends on the thing, a real migration path, and a plan for the accounts that will need a human.

Working from a brief

Given what's being deprecated and why, produce the full plan — infer the risk tiers from usage and contract exposure. Right-size the runway to how hard the migration is (an internal flag flip is weeks; a public API is many months). If there's no migration path yet, flag that as a blocker before any announcement.

Required Inputs

Ask for (if not provided, else infer and label the assumption):

• What's being deprecated and why (cost, security, strategy, replaced-by)
• Who depends on it — rough usage, and which segments/contracts are exposed
• The replacement / migration path (or that there isn't one yet)
• Hard constraints — a forcing date (security, legal, contract), team capacity

Output Format

Deprecation policy in one line

The principle you're committing to (e.g. "announce → N months deprecated (works, warns) → sunset, with a migration path live before we announce").

Timeline

Include grace periods and any extension policy for large accounts.

Tiered messaging

Segmented by dependence, not one blast:

• Tier 1 — heavy/contractual users: proactive, human (CSM/AM), often a call + tailored plan.
• Tier 2 — active users: direct email + in-product warning + migration guide.
• Tier 3 — light/dormant: changelog, docs banner, deprecation headers.

For each: the core message (what, when, why, what to do), the ask, and the escalation path.

Migration guide outline

The structure of the how-to: before/after, step-by-step, code/config examples, a mapping table (old → new), FAQ, and where to get help.

Channel plan

Which channels fire at which phase — email, in-product, docs/changelog, API deprecation headers/Sunset header, status page, community/social — and the cadence (announce, reminders at intervals, final notice).

Internal escalation playbook

The at-risk account list, who owns each, the CSM talking points, the "customer can't migrate in time" decision tree, and the exception/extension approval path.

Quality Checks

• A migration path exists and is referenced everywhere before any customer message goes out
• Runway is sized to migration difficulty, with grace periods stated
• Messaging is tiered by dependence; Tier-1 accounts get a human, not a blast
• Every message says what, when, why, and the exact next step
• The channel cadence includes reminders and a final notice, not a single announcement
• High-risk accounts have a named owner and an escalation/extension path

Anti-Patterns

• Too little runway for the migration actually required
• A silent breaking change, or burying it in a changelog nobody reads
• Announcing before the migration path is live
• One-size messaging that treats a whale like a dormant free user
• No plan for the accounts that physically can't migrate in time
• "Why" that blames the customer or the old system instead of owning the change
