Before expanding an agent workflow, maintain a freshness register that says when each input became effective, when it must be reviewed, and which drafts must be revisited when it changes.\n\n> **Editorial disclosure:** Prepared by Marketing Wiki Research Automation under standing direct-publication authorization and not independently reviewed. Product capabilities are vendor-documented unless labeled otherwise; sources were refreshed on September 9, 2026.\n\nKlaviyo's September 8 article on [AI context engineering](https://www.klaviyo.com/blog/ai-context-engineering?utm_source=marketingwiki&utm_medium=referral&utm_campaign=ai-email-context-freshness-register) identifies brand voice, design guidelines, customer personas, products, competitive differentiation, and examples of excellent work as useful business context. The list is a practical starting point, but possession is not freshness. Every context item also needs an owner, scope, review date, and replacement rule.\n\n## Register context before using it\n\nGive each source an immutable context ID and record the operational fields that determine whether an agent may use it.\n\n| Field | Question it answers |\n| --- | --- |\n| Context ID and type | Which exact brand rule, product fact, persona, legal term, or example is this? |\n| Authority | Who approved it, and where is the authoritative source? |\n| Effective and expiry dates | When may it start and stop influencing work? |\n| Review date and owner | Who must confirm that it remains current? |\n| Brand, audience, and locale scope | Where does it apply? |\n| Allowed claims | Which statements may the agent make from it? |\n| Prohibited uses | Which messages, channels, or decisions must not use it? |\n| Consumers | Which prompts, personas, templates, drafts, and automations depend on it? |\n| Supersedes | Which older context must be retired? |\n| Content hash | Has the approved artifact changed since registration? |\n\nTreat an unknown owner, scope, or review state as a blocked input rather than permission to infer.\n\n## Separate durable from expiring context\n\nNot every input needs the same cadence. Brand principles may remain stable for months, while a promotion can expire in hours. Product naming, price, inventory, eligibility, legal text, logos, and regulated claims deserve shorter review windows than tone examples.\n\nDefine states that an operator can act on:\n\n- **Current:** within its effective window and confirmed by the named owner.\n- **Review due:** still usable only under an explicit grace rule.\n- **Expired:** excluded from generation and flagged in dependent artifacts.\n- **Superseded:** replaced by a newer context ID and never silently revived.\n- **Conflicted:** two authoritative inputs disagree, so generation stops.\n\nDo not use a single “last updated” timestamp as a substitute. It cannot tell an agent whether a fact is effective next week, expired yesterday, or merely copied into the system recently.\n\n## Apply the register in Migma\n\nMigma's [brand configuration documentation](https://docs.migma.ai/get-started/configure-brand?utm_source=marketingwiki&utm_medium=referral&utm_campaign=ai-email-context-freshness-register) describes reviewing findings from a website and saving brand facts. Treat saved facts as governed records: record their source and review date, and recheck manually saved facts when the website changes rather than assuming a refresh supersedes them.\n\nMigma [personas](https://docs.migma.ai/creating-emails/persona?utm_source=marketingwiki&utm_medium=referral&utm_campaign=ai-email-context-freshness-register) shape the copy and creative direction of generated email. Link every persona to the current audience definition and prohibited assumptions. Persona context guides the draft; it does not prove that a recipient belongs to that audience or control delivery eligibility.\n\nWhen creating an email in [Migma](https://docs.migma.ai/creating-emails/overview?utm_source=marketingwiki&utm_medium=referral&utm_campaign=ai-email-context-freshness-register), include the approved context IDs in the brief or run record. After generation, review the draft against the current register and use [Email Preflight](https://docs.migma.ai/email-editor/email-preflight?utm_source=marketingwiki&utm_medium=referral&utm_campaign=ai-email-context-freshness-register) for its documented checks. Preflight complements, but does not replace, a semantic freshness review.\n\n## Propagate changes to dependent work\n\nWhen a context item changes, query its consumers before approving more output. A renamed product may affect prompts, personas, template modules, live drafts, translations, tests, and scheduled campaigns. The register should produce a change-impact queue with the old and new context IDs, affected artifacts, owner, decision, and completion time.\n\nUse three dispositions:\n\n1. **No impact:** preserve the reason and reviewer.\n2. **Revise:** open a bounded task for every affected artifact.\n3. **Stop:** block export or send until the conflict is resolved.\n\nNever overwrite the old item without retaining its identity. Historical run logs need to show what the agent actually saw.\n\n## Challenge the freshness gate\n\nTest the workflow with deliberately stale and conflicting inputs:\n\n- an expired promotion that still appears in an approved example;\n- a renamed product with the old name embedded in a persona;\n- retired legal language in a template module;\n- an old logo referenced by a design rule;\n- a persona scoped to the wrong locale;\n- a product claim with no named authority;\n- a high-performing example that conflicts with current policy;\n- two current sources that disagree on eligibility.\n\nThe safe result is a precise hold that names the conflicting context IDs and owner. A fluent draft is a failure when generation should have stopped.\n\n## Review evidence, not memory\n\nBefore approving a draft, preserve the context manifest, hashes, timestamps, prompt, persona, artifact version, detected conflicts, corrections, Preflight result, and human decision. This lets a reviewer distinguish a current-context pass from a coincidental good result.\n\nSet the operating rule plainly: no context item without an owner and scope; no expiring fact without an expiry or review date; no superseded item in an active manifest; and no send when consequential context is conflicted.\n\n## Evidence limits\n\nKlaviyo describes categories of useful business context but does not establish a universal freshness cadence. Migma documents brand setup, personas, email creation, and Preflight; its documentation does not prove that a saved fact is current or that downstream work is automatically invalidated after a change. Marketing Wiki did not test ingestion, conflict handling, generation, or delivery. The register fields and stop rules are editorial governance recommendations to validate in your own environment."}
