Cross-Tool Agent Memory Layer Build (7-12 days)
A productized engagement that stands up one persistent, exportable memory layer so every agent on the client's stack recalls the same project decisions, brand rules, and entity relationships instead of relearning them each session.
- A named client sponsor who owns the agent stack and can approve write access to shared memory; an inventory of every AI tool currently touching client work (coding agents, chat assistants, automation runners); a written data boundary stating which client facts may enter shared memory and which stay local; export and deletion guarantees confirmed in writing by the memory vendor before any data is written; a sandbox project with 2-3 weeks of real session history to test recall against.
- 1.Inventory every agent and assistant in the client's stack, noting which ones currently start each session with zero context
- 2.Log the top 10 facts re-explained to agents each week (architecture choices, tone rules, naming conventions, past fixes)
- 3.Measure baseline re-prompt time per person per week and convert it to a dollar figure
- 1.Choose the memory architecture: entity-graph recall, structured project archive, or federated recognition across tools
- 2.Score each candidate on export format, deletion path, and whether retrieval runs without an LLM in the loop
- 3.Confirm the connector path (MCP or equivalent) works with the client's existing tools before committing
- 1.Define the memory schema: entities, relationships, tags, provenance fields, and freshness rules
- 2.Write the write policy: what agents may store automatically versus what requires human approval
- 3.Draft the retention schedule and the client-facing data boundary one-pager
- 1.Stand up the memory layer in a sandbox and connect the first two agents
- 2.Seed it with 20-30 real facts pulled from the client's recent project history
- 3.Verify a fact written by one agent is retrievable by the second agent without manual copying
- 1.Run recall tests on multi-hop questions the client actually asks (for example, which campaign used which asset and why)
- 2.Time retrieval latency and record failures where the layer returns nothing useful
- 3.Tune tags and relationship links until the failure list is empty or explained
- 1.Connect the remaining agents in the stack and confirm cross-tool recognition
- 2.Test the export path end to end: dump the full memory store, re-import it into a clean instance, confirm nothing is lost
- 3.Document the export procedure as a runbook the client can execute without the agency
- 1.Train two client staff members on writing to memory, correcting bad entries, and pruning stale facts
- 2.Hand over the schema document and the write policy with a 30-minute walkthrough
- 3.Agree the weekly memory hygiene slot on the client's calendar
- 1.Run a full week of live client work through the layer and collect recall accuracy numbers
- 2.Compare re-prompt time against the day-1 baseline and calculate hours recovered
- 3.Flag any agent that still ignores memory and document the workaround
- 1.Write the handover pack: architecture diagram, schema, policies, export runbook, and baseline-versus-current metrics
- 2.Present findings to the sponsor with a recommendation on which agents to add next quarter
- 3.Close with the retainer scope: monthly hygiene, schema updates, and vendor migration watch
Agencies bill this as infrastructure, not hours, because the deliverable is institutional knowledge that survives staff turnover and tool swaps. The margin holds when the memory layer exports cleanly: the client can leave the vendor without losing the archive, which removes the main objection to paying for setup. Recurring hygiene work (pruning stale facts, updating schemas as the stack changes) converts a one-time build into a retainer line that renews without new sales effort.
- Memory architecture decision memo comparing graph-based recall, structured archives, and federated recognition against the client's stack
- Written memory schema with entity types, relationship rules, tags, provenance fields, and freshness thresholds
- Export and migration runbook proving the full memory store can be dumped, re-imported, and verified without vendor assistance
- Recall accuracy report with baseline versus post-deployment re-prompt time and hours recovered per person per week
- Staff training session recording plus a one-page write policy covering what agents may store automatically
A fact written by one agent is correctly retrieved by a different agent in a live client session, and the full memory store has been exported, re-imported into a clean instance, and verified with zero data loss.
