Using Context Effectively

Effective Context is not about volume of documents. It is about covering the four types of guidance AI needs to make decisions the way your organization would. Before adding documents, check your coverage against these four categories.

If you are still deciding whether Context is worth the effort, start with What is Workspace Context?.

The four guidance types

1. Requirements

What the system must do and satisfy. This is the "must be true" layer.

What to include: functional and non-functional requirements, SLAs and SLOs, performance and scale targets, availability and recovery objectives, data residency and retention requirements, integration and interoperability requirements.

What it changes: recommendations and designs are evaluated against what the system is obligated to deliver, so proposals that would violate a requirement are filtered out before they reach you.

2. Strategy and objectives

Where you are headed and why. This is the "optimizing toward" layer.

What to include: business strategy and KPIs, product strategy and roadmap, technology strategy such as cloud posture, build versus buy stance, and platform direction, migration and modernization goals, cost and efficiency targets, planned divestitures or separations.

What it changes: recommendations are prioritized by what moves your goals, not by generic impact. Two organizations with identical stacks and different strategies should get different guidance. This category is what makes that true.

3. Policies, guardrails, and constraints

What is off-limits and what boundaries apply. This is the "must not" layer.

What to include: security policies and access controls, compliance obligations such as SOC 2, HIPAA, and GDPR, procurement and vendor policies, budget constraints, approved and prohibited services, data classification and handling rules, the explicit do-not-do list.

What it changes: guardrails are enforced as constraints, not offered as advice. Designs and recommendations that would cross a policy line do not get generated in the first place. This is where governance stops being a review gate and becomes a property of the output.

4. Standards and architecture encoding

How things are done here. This is the "our way" layer, and the one most organizations under-invest in.

What to include: architecture principles, approved patterns and reference architectures, golden paths for common service types, preferred services and tooling, naming and tagging standards, settled trade-offs and past architecture decisions with their rationale.

What it changes: this is how architects scale themselves. Standards that today live in slide decks and stale wikis, applied only when an architect is in the room, become inheritable by every design and every Archie answer. A developer asking "what is the recommended pattern for X" gets your pattern. See Architecture Encoding for the full treatment.

Global or Workspace: where guidance belongs

Place each item at the level where it applies:

• Global Context: anything true for the whole organization. Enterprise strategy, compliance obligations, security policies, org-wide standards and golden paths. Encode once, inherit everywhere.
• Workspace Context: anything specific to a system, team, or initiative. This workspace's requirements, its lifecycle stage, its migration goals, its local constraints.

A good default: policies and standards trend global, requirements and objectives trend workspace. When in doubt, place it global and override locally only where a workspace genuinely differs.

How to build coverage

• Start with what exists. Most organizations already have the source material: strategy decks, security policies, architecture principle docs, ADRs, platform documentation. Upload these first rather than authoring from scratch. See What Documents to Upload for a concrete catalog.
• Complete the questionnaires. The architecture context questionnaire captures scope, lifecycle stage, constraints, and third-party tooling in structured form, and closes gaps documents leave open. See Questionnaires.
• Audit against the four categories. For each workspace and for Global Context, ask whether each of the four guidance types is represented. The most common gap is category four, standards and architecture encoding, because that knowledge usually lives in people rather than documents.
• Write down the unwritten rules. The highest-value Context entries are often the ones that were never documented: the settled trade-offs, the "we tried that and here is why we do not," the do-not-do list. If an architect would say it in a design review, it belongs in Context.

Initial setup takes 30 to 60 minutes for the first cut, and delivers gains immediately. Business intent and the live architecture state model carry most of the load on day one. Standards and patterns deepen over time.

Maintaining Context

Context earns compounding returns only if it stays current. This maintenance is not overhead. It is the encoding loop, and it becomes a core, ongoing part of the architect's role.

• Name an owner. One person accountable for Context accuracy per tenant, with workspace owners for local context. This is the most important governance decision in adopting Catio.
• Update on decisions, not on a calendar. When a design review or exception review settles something new, encode the lesson into Context the same week. Every future spec then inherits it.
• Prune what no longer applies. Stale guidance is worse than missing guidance, because it is enforced. Retire superseded strategy docs and expired constraints deliberately.
• Watch the feedback signals. If recommendations are being rejected for missing information, or designs need repeated correction on the same point, that is a Context gap telling you where to invest next. See View Workspace Context for tracing an entry back to its source.

Anti-patterns to avoid

• Dumping the wiki. Uploading everything indiscriminately dilutes signal. Curate for the four categories.
• Encoding aspirations as constraints. If a standard is not actually enforced in your organization yet, mark it as direction, not as a guardrail. Otherwise outputs will fight your present reality.
• Letting Context lag the org. After a reorg, divestiture, or strategy shift, update Context first. It is the one place where a single update propagates everywhere.
• Treating Context as write-once. The organizations that get the most from Catio treat Context encoding as a standing architect responsibility, not a setup task.
