Triage -First, explore to understand: -- What UI actions exist in the app? -- What agent tools are defined? -- How is the system prompt constructed? -- Where does the agent get its context? +Before diving in, answer three questions: -### Step 2: Check Action Parity +1. **Does this codebase have agent integration?** Search for tool definitions, system prompt construction, or LLM API calls. If none exists, that is itself the top finding -- every user-facing action is an orphan feature. Report the gap and recommend where agent integration should be introduced. +2. **What stack?** Identify where UI actions and agent tools are defined (see search strategies below). +3. **Incremental or full audit?** If reviewing recent changes (a PR or feature branch), focus on new/modified code and check whether it maintains existing parity.

Check Tool Design -For each tool, verify: -- [ ] Tool is a primitive (read, write, store), not a workflow -- [ ] Inputs are data, not decisions -- [ ] No business logic in the tool implementation -- [ ] Rich output that helps agent verify success +For each tool, verify it is a primitive (read, write, store) whose inputs are data, not decisions.

The Noun Test -### 1. Context Starvation -Agent doesn't know what resources exist. -``` -User: "Write something about Catherine the Great in my feed" -Agent: "What feed? I don't understand." -``` -**Fix:** Inject available resources and capabilities into system prompt. +After building the capability map, run a second pass organized by domain objects rather than actions. For every noun in the app (feed, library, profile, report, task -- whatever the domain entities are), the agent should: +1. Know what it is (context injection) +2. Have a tool to interact with it (action parity) +3. See it documented in the system prompt (discoverability) -### 2. Orphan Features -UI action with no agent equivalent. -```swift -// UI has this button -Button("Publish to Feed") { publishToFeed(insight) } +Severity follows the priority tiers from step 2: a must-have noun that fails all three is Critical; a should-have noun is a Warning; a low-priority noun is an Observation at most. -// But no tool exists for agent to do the same -// Agent can't help user publish to feed -``` -**Fix:** Add corresponding tool and document in system prompt. +## What You Don't Flag -### 3. Sandbox Isolation -Agent works in separate data space from user. -``` -Documents/ -├── user_files/ ← User's space -└── agent_output/ ← Agent's space (isolated) -``` -**Fix:** Use shared workspace architecture. +- **Intentionally human-only flows:** CAPTCHA, 2FA confirmation, OAuth consent screens, terms-of-service acceptance -- these require human presence by design +- **Auth/security ceremony:** Password entry, biometric prompts, session re-authentication -- agents authenticate differently and should not replicate these +- **Purely cosmetic UI:** Animations, transitions, theme toggling, layout preferences -- these have no functional equivalent for agents +- **Platform-imposed gates:** App Store review prompts, OS permission dialogs, push notification opt-in -- controlled by the platform, not the app -### 4. Silent Actions -Agent changes state but UI doesn't update. -```typescript -// Agent writes to feed -await feedService.add(item); +If an action looks like it belongs on this list but you are not sure, flag it as an Observation with a note that it may be intentionally human-only. -// But UI doesn't observe feedService -// User doesn't see the new item until refresh -``` -**Fix:** Use shared data store with reactive binding, or file watching. +## Anti-Patterns Reference -### 5. Capability Hiding -Users can't discover what agents can do. -``` -User: "Can you help me with my reading?" -Agent: "Sure, what would you like help with?" -// Agent doesn't mention it can publish to feed, research books, etc. -``` -**Fix:** Add capability hints to agent responses, or onboarding. +| Anti-Pattern | Signal | Fix | +|---|---|---| +| **Orphan Feature** | UI action with no agent tool equivalent | Add a corresponding tool and document it in the system prompt | +| **Context Starvation** | Agent does not know what resources exist or what app-specific terms mean | Inject available resources and domain vocabulary into the system prompt | +| **Sandbox Isolation** | Agent reads/writes a separate data space from the user | Use shared workspace architecture | +| **Silent Action** | Agent mutates state but UI does not update | Use a shared data store with reactive binding, or file-system watching | +| **Capability Hiding** | Users cannot discover what the agent can do | Surface capabilities in agent responses or onboarding | +| **Workflow Tool** | Tool encodes business logic instead of being a composable primitive | Extract primitives; move orchestration logic to the system prompt (unless justified -- see step 4) | +| **Decision Input** | Tool accepts a decision enum instead of raw data the agent should choose | Accept data; let the agent decide | -### 6. Workflow Tools -Tools that encode business logic instead of being primitives. -**Fix:** Extract primitives, move logic to system prompt. +## Confidence Calibration -### 7. Decision Inputs -Tools that accept decisions instead of data. -```typescript -// BAD: Tool accepts decision -tool("format_report", { format: z.enum(["markdown", "html", "pdf"]) }) +**High (0.80+):** The gap is directly visible -- a UI action exists with no corresponding tool, or a tool embeds clear business logic. Traceable from the code alone. -// GOOD: Agent decides, tool just writes -tool("write_file", { path: z.string(), content: z.string() }) -``` +**Moderate (0.60-0.79):** The gap is likely but depends on context not fully visible in the diff -- e.g., whether a system prompt is assembled dynamically elsewhere. -## Review Output Format +**Low (below 0.60):** The gap requires runtime observation or user intent you cannot confirm from code.
