Coding Plan

Summary

Retrieve PR comments first using the provided PAT to incorporate agent-suggested corrections
Apply all fixes in parallel (sanitizedHistory, transpilePackages, ESM imports, serverExternalPackages) rather than testing sequentially
Address import graph fragility that causes webpack instability when unrelated changes are made
Commit directly to PR Implement Elevation Heat Map for Resolution Search #544 using the PAT to fix the branch

Design Choices

Design Choice 1: Root Cause is Multi-Factor

Options Considered:

Single root cause requiring one fix
Multiple contributing factors requiring parallel fixes

Chosen Option: 2

Rationale: Option 2: Investigation identified at least four contributing issues (incomplete sanitizedHistory patch, invalid transpilePackages, CommonJS require() in ESM context, missing serverExternalPackages). All should be applied together.

Design Choice 2: PR #544 Contains Agent-Suggested Fixes

Options Considered:

Manually identify all fixes from codebase analysis
Pull agent-suggested fixes from PR comments and apply them

Chosen Option: 2

Rationale: Option 2: Use the provided PAT to retrieve PR #544 comments and incorporate agent-suggested corrections before applying additional manual fixes.

`chat-panel.patch`, `layout.patch`) to avoid applying duplicate changes
- Commit the applied corrections with appropriate attribution

Phase 2: Apply All Primary Fixes

Apply all identified fixes together as parallel changes rather than sequential hypothesis testing.

Task 1: Complete the sanitizedHistory Usage

Apply the missing piece of the patch by using the already-created sanitizedHistory variable.

In app/actions.tsx, locate the aiState.done() call inside processResolutionSearch() (approximately line 159-175)
Change the messages array spread from ...aiState.get().messages to ...sanitizedHistory
The sanitizedHistory variable already exists (lines 138-149) and replaces image data with 'IMAGE_PROCESSED' placeholder strings
This prevents large base64 image blobs from being serialized into AI state

Task 2: Fix transpilePackages Configuration

Remove the self-referential package from transpilePackages which causes circular module resolution.

In next.config.mjs, locate the transpilePackages array (line 12)
Remove 'QCX' from the array—you cannot transpile your own package
Keep only external local packages: transpilePackages: ['mapbox_mcp']

Task 3: Replace CommonJS require() with ESM Import

Address the module loading conflict in geospatial tool.

In lib/agents/tools/geospatial.tsx, locate the require() call (line 61)
Replace require('../../../mapbox_mcp_config.json') with ESM import syntax
Use static import at top of file: import mapboxMcpConfig from '../../../mapbox_mcp_config.json'
Adjust error handling since static imports throw at module load time rather than inside try/catch

Task 4: Add serverExternalPackages for Problematic Dependencies

Configure Next.js to externalize packages that webpack cannot bundle correctly.

In next.config.mjs, add the serverExternalPackages array (Next.js 15 API)
Include @modelcontextprotocol/sdk due to its .js extension ESM imports
Include packages from PR Implement Elevation Heat Map for Resolution Search #544's embeddings feature: geotiff, @google-cloud/storage, csv-parse, proj4
Full config: serverExternalPackages: ['@modelcontextprotocol/sdk', 'geotiff', '@google-cloud/storage', 'csv-parse', 'proj4']

Task 5: Verify Patch File Changes Are Applied

Confirm that all changes from the patch files are correctly in place.

Verify summaryStream initialization uses 'Analyzing map view...' instead of empty string (around line 87/99 in app/actions.tsx)
Verify uiStream.update(answerSection) is used instead of uiStream.append(answerSection) (around line 252 in app/actions.tsx)
Remove dead Sidebar import from app/layout.tsx line 9 (the component was removed but import remains)
Remove dead Plus import from components/chat-panel.tsx (replaced by Sprout but import not cleaned up)

Task 6: Clear Build Artifacts and Rebuild

Ensure fresh build artifacts with all fixes applied.

Delete .next directory to clear all build artifacts
Clear any node_modules caches: rm -rf node_modules/.cache
Perform a full rebuild to generate new webpack chunks

🤖 Prompt for AI agents

Apply all identified fixes together as parallel changes in `app/actions.tsx`,
`next.config.mjs`, and `lib/agents/tools/geospatial.tsx`. The goal is to resolve
the webpack runtime error by addressing all contributing issues simultaneously.

**Fix 1: Complete sanitizedHistory Usage (`app/actions.tsx`)**
- Locate the `aiState.done()` call inside `processResolutionSearch()`
(approximately lines 159-175)
- Replace `...aiState.get().messages` with `...sanitizedHistory` in the messages
array spread
- The `sanitizedHistory` variable is already defined (lines 138-149); it
replaces image data with `'IMAGE_PROCESSED'` placeholder strings to prevent
large base64 blobs from being serialized into AI state

**Fix 2: transpilePackages Configuration (`next.config.mjs`)**
- Locate the `transpilePackages` array (around line 12)
- Remove the self-referential `'QCX'` entry
- Keep only: `transpilePackages: ['mapbox_mcp']`

**Fix 3: ESM Import Conversion (`lib/agents/tools/geospatial.tsx`)**
- Locate the CommonJS `require()` call at line 61
- Replace `require('../../../mapbox_mcp_config.json')` with a static ESM import
at the top of the file: `import mapboxMcpConfig from
'../../../mapbox_mcp_config.json'`
- Adjust any surrounding error handling, since static imports throw at module
load time rather than inside a try/catch block

**Fix 4: serverExternalPackages Configuration (`next.config.mjs`)**
- Add the `serverExternalPackages` array using the Next.js 15 API
- Set: `serverExternalPackages: ['@modelcontextprotocol/sdk', 'geotiff',
'@google-cloud/storage', 'csv-parse', 'proj4']`

**Fix 5: Verify Patch File Changes Are Applied**
- In `app/actions.tsx`: confirm `summaryStream` is initialized with `'Analyzing
map view...'` (around line 87/99)
- In `app/actions.tsx`: confirm `uiStream.update(answerSection)` is used rather
than `uiStream.append(answerSection)` (around line 252)
- In `app/layout.tsx`: remove the dead `Sidebar` import at line 9
- In `components/chat-panel.tsx`: remove the dead `Plus` import (replaced by
`Sprout`)

**Fix 6: Clear Build Artifacts**
- Delete the `.next` directory
- Run `rm -rf node_modules/.cache`
- Perform a full rebuild to generate fresh webpack chunks with all fixes applied

Phase 3: Stabilize the Fragile Import Graph

Address the underlying architectural issue causing unrelated changes to destabilize the webpack/vision module chain.

Task 1: Identify Cross-Boundary Import Patterns

Document the server-side tool files that import 'use client' components with heavy dependencies.

lib/agents/tools/geospatial.tsx imports BotMessage from @/components/message (a 'use client' component)
components/message.tsx has import 'katex/dist/katex.min.css' CSS side-effect at module scope
This creates a server→client boundary crossing with CSS side-effects that destabilizes webpack chunk splitting
Same pattern exists in lib/agents/writer.tsx and lib/agents/researcher.tsx

Task 2: Evaluate Import Graph Stabilization Options

Determine the best approach to stabilize the fragile import graph.

Option A: Add 'use server' directives to agent tool files to clarify the module boundary
Option B: Move CSS imports from top-level to dynamic within useEffect where possible
Option C: Accept the current structure and rely on serverExternalPackages to isolate problem modules
Document chosen approach and rationale; Option C may be sufficient after Phase 2 fixes

Task 3: Add Browser API Guards to image-utils

Prevent potential SSR failures from browser-only APIs.

In lib/utils/image-utils.ts, add runtime check at the top of compressImage function
Add guard: if (typeof window === 'undefined') throw new Error('compressImage must be called client-side');
This prevents the function from silently failing if accidentally called during server-side rendering

Address the underlying architectural issue causing unrelated changes to
destabilize the webpack/vision module chain. The goal is to document
cross-boundary import patterns, evaluate stabilization options, and add SSR
guards.

**Identify Cross-Boundary Import Patterns:**
- Note that `lib/agents/tools/geospatial.tsx` imports `BotMessage` from
`@/components/message`, which is a `'use client'` component
- Note that `components/message.tsx` has `import 'katex/dist/katex.min.css'` as
a CSS side-effect at module scope
- This server→client boundary crossing with a CSS side-effect destabilizes
webpack chunk splitting
- Identify if the same pattern exists in `lib/agents/writer.tsx` and
`lib/agents/researcher.tsx`

**Evaluate and Document Import Graph Stabilization Options:**
- Option A: Add `'use server'` directives to agent tool files to explicitly
clarify the module boundary
- Option B: Move CSS imports from top-level to dynamic within `useEffect` where
possible
- Option C: Accept the current structure and rely on `serverExternalPackages` to
isolate problem modules
- Document the chosen approach and rationale; Option C may be sufficient after
Phase 2 fixes are applied

**Add Browser API Guard to `lib/utils/image-utils.ts`:**
- Locate the `compressImage` function
- Add the following guard at the top of the function: `if (typeof window ===
'undefined') throw new Error('compressImage must be called client-side');`
- This prevents silent failures if the function is accidentally called during
server-side rendering

Research

The resolution search feature is a satellite image analysis system in a Next.js application. It processes map screenshots via app/actions.tsx server actions, calls the resolutionSearch agent in lib/agents/resolution-search.tsx, and renders results through ResolutionCarousel and GeoJsonLayer components. The codebase contains three patch files (app_actions_diff.patch, chat-panel.patch, layout.patch) documenting recent changes. Investigation revealed multiple potential issues: an incomplete patch where sanitizedHistory is created but not used, a problematic transpilePackages configuration, and CommonJS/ESM module loading conflicts in agent tools.
