Skillsync

Skillsync indexes every past session across Claude Code, Codex, Cursor, OpenCode and six other agents, then returns cited prior context to each new prompt in under one second. For a dev agency, that means a solved client problem stays solved across engineers and across agents, which is the difference between billing for rediscovery and billing for delivery. The Pro tier at $20 per seat per month is the cost basis an agency can wrap into a productivity retainer.

Skillsync's value is not linear with seat count; it compounds with the number of indexed sessions per workspace. A dev agency that installs the plugin for Claude Code, Codex, or OpenCode on day one gets almost nothing back, because recall has no prior work to surface. The curve bends once a client workspace accumulates real engineering prompts across a few weeks, at which point each new prompt pulls cited prior context in under 1 second. This reframes the $20 per seat per month Pro cost as an indexing investment rather than a per-user tool fee: the same seat is worth more in month three than in week one. Practically, agencies should bill the $1,800 Solo Dev Setup as the index-building phase and only attach a productivity retainer once the workspace has enough session history to make recall pay off. Selling recall before the corpus exists is the fastest way to lose the retainer.

Memory Portability Premium is the strategic value an agency captures when its agent memory layer exports cleanly, measured as the gap between what client context is worth inside a tool and what survives leaving it. Agencies accumulate client-specific architecture, brand rules, and debugging history across long-running retainers, and that accumulated context is the real deliverable asset. When the memory layer is a closed silo, switching tools means rebuilding months of context from scratch, so the premium collapses to zero and the vendor captures the rent. Knownbase stores decisions, debugging discoveries, and constraints as project notes retrievable across sessions and tools, which keeps the archive portable. Cogni runs retrieval through an entity graph with spreading activation and no LLM in the path, so connected facts stay model-agnostic. Bourdon federates one memory across Claude, Codex, Cursor, and Copilot, so a fact learned in one tool is recognized in the others. Before standardizing, test one export: pull a client's memory out and read it without the original tool.

Memory Portability Premium is the practice of valuing an agent memory layer by what survives the exit, not by what it does on day one. Every connector in this category stores something an agency paid to learn: client architecture decisions, brand constraints, debugging discoveries, campaign rulings. If that store exports as clean, structured, attributable records, the knowledge compounds across tools and staff turnover. If it exports as an opaque blob, the agency rents its own institutional memory and repays the learning cost at every switch. The premium is the delta between those two outcomes, and it is measurable in re-prompt hours and re-onboarding days. A concrete test: ask whether a layer like Knownbase or OzBrain can hand back tagged, provenance-linked notes another MCP-compatible agent can read without the original vendor present. Terms risk compounds this. Roughly 60% of 175 AI tools changed monetization-relevant terms in 15 weeks, so a memory vendor's export policy can shift after your client retainer is signed. Price portability before capability.

Adopt Skillsync Pro when agent-switching across a shared client codebase is routine, and stay on the open-source tier when a single agent and a single engineer cover the work.

Before standardizing on any agent memory layer, export a full client knowledge set, re-import it into a second tool, and confirm the entity relationships survive the round trip.

IF your delivery team cycles between Claude Code, Codex, Cursor, and OpenCode and repeatedly re-solves problems already solved in past sessions, THEN buy Pro at $20 per seat per month for shared workspaces and the skill library. IF you need white-label client-facing recall or runtime agent traces, DEFER until you can negotiate the Team plan, which is contact-sales only. IF you run a single agent on a single codebase, SKIP: the open-source tier already covers MCP session search and moving sessions between agents at $0.
