16GitHub Codespaces requires a specific installation approach because traditional methods (peer directories, bind mounts) don't work in cloud environments. This method uses `postCreateCommand` to clone HVE-Core into the persistent `/workspaces` directory.
17
18## When to Use This Method
19
20✅ **Use this when:**
21
22* Your project runs exclusively in Codespaces
23* You want automatic HVE-Core setup for all users
24* You need zero-config onboarding for contributors
25
26❌ **Consider alternatives when:**
27
28* You also need local devcontainer support → [Multi-Root Workspace](multi-root.md)
29* Your team needs version control → [Submodule](submodule.md)
30* You're using local VS Code only → [Peer Clone](peer-clone.md)
31
32## Why Other Methods Don't Work in Codespaces
33
34| Feature | Local Devcontainer | GitHub Codespaces |
35|----------------------------|--------------------|------------------------------|
36| `${localWorkspaceFolder}` | ✅ Resolves to host | ❌ Not available |
37| Bind mounts to host | ✅ Full support | ❌ No host access |
38| Persistent storage | Host filesystem | `/workspaces` only |
39| User settings modification | ✅ Via file system | ❌ Only via Settings Sync[^1] |
40
41[^1]: User-level settings require Settings Sync. Workspace/container-level settings can still be configured via `devcontainer.json` using `customizations.vscode.settings`.
42
43## How It Works
44
45Codespaces has a specific storage model:
46
47```text
48/
49├── workspaces/ # ✅ PERSISTENT - survives stops/restarts
50│ ├── your-repo/ # Your cloned repository
51│ └── hve-core/ # 👈 HVE-Core goes here
52├── home/codespace/ # ⚠️ Semi-persistent (survives stops, not rebuilds)
53└── <system-dirs>/ # ❌ Not persistent
54```
55
56The `postCreateCommand` clones HVE-Core into `/workspaces/hve-core` where it persists across Codespace sessions.
57
58## Quick Start
59
60Use the `hve-core-installer` agent:
61
621. Open GitHub Copilot Chat (`Ctrl+Alt+I`)
632. Select `hve-core-installer` from the agent picker
643. Say: "Install HVE-Core for Codespaces"
654. Follow the guided setup
66
67## Manual Setup
68
69### Step 1: Update devcontainer.json
70
71Add the clone command and VS Code settings:
72
73```jsonc
74{
75 "name": "My Project with HVE-Core",
76 "image": "mcr.microsoft.com/devcontainers/base:ubuntu",
77
78 "postCreateCommand": "[ -d /workspaces/hve-core ] || git clone --depth 1 https://github.com/microsoft/hve-core.git /workspaces/hve-core",
79
80 "customizations": {
81 "vscode": {
82 "settings": {
83 "chat.agentFilesLocations": {
84 "/workspaces/hve-core/.github/agents/ado": true,
85 "/workspaces/hve-core/.github/agents/data-science": true,
86 "/workspaces/hve-core/.github/agents/design-thinking": true,
87 "/workspaces/hve-core/.github/agents/github": true,
88 "/workspaces/hve-core/.github/agents/installer": true,
89 "/workspaces/hve-core/.github/agents/project-planning": true,
90 "/workspaces/hve-core/.github/agents/hve-core": true,

98 "/workspaces/hve-core/.github/prompts/hve-core": true,
99 "/workspaces/hve-core/.github/prompts/security-planning": true
100 },
101 "chat.instructionsFilesLocations": {
102 "/workspaces/hve-core/.github/instructions/ado": true,
103 "/workspaces/hve-core/.github/instructions/coding-standards": true,
104 "/workspaces/hve-core/.github/instructions/design-thinking": true,
105 "/workspaces/hve-core/.github/instructions/github": true,
106 "/workspaces/hve-core/.github/instructions/hve-core": true,
107 "/workspaces/hve-core/.github/instructions/shared": true
108 },

110 "/workspaces/hve-core/.github/skills": true,
111 "/workspaces/hve-core/.github/skills/shared": true
112 }
113 }
114 }
115 }
116}
117```
118
119### Step 2: Commit and Push
120
121```bash
122git add .devcontainer/devcontainer.json
123git commit -m "feat: add HVE-Core support for Codespaces"
124git push
125```
126
127### Step 3: Create or Rebuild Codespace
128
129* **New Codespace:** Create from the updated branch
130* **Existing Codespace:** Rebuild (`Ctrl+Shift+P` → "Codespaces: Rebuild Container")
131
132### Step 4: Validate Installation
133
1341. Open GitHub Copilot Chat (`Ctrl+Alt+I`)
1352. Click the agent picker dropdown
1363. Verify HVE-Core agents appear (task-planner, task-researcher, prompt-builder)
137

250### Dual-Environment (Local + Codespaces)
251
252For projects needing HVE-Core in both local devcontainers and Codespaces:
253
254```jsonc
255{
256 "name": "HVE-Core (Local + Codespaces)",
257 "image": "mcr.microsoft.com/devcontainers/base:ubuntu",
258
259 // Clone if not already present (Codespaces path)
260 "postCreateCommand": "[ -d /workspaces/hve-core ] || git clone --depth 1 https://github.com/microsoft/hve-core.git /workspaces/hve-core",
261
262 // Local only: mount peer directory (silently fails in Codespaces)
263 "mounts": [
264 "source=${localWorkspaceFolder}/../hve-core,target=/workspaces/hve-core,type=bind,readonly=true,consistency=cached"
265 ],
266

268 "vscode": {

322 }
323 }
324 }
325 }
326}
327```
328
329## Updating HVE-Core
330
331### Manual Update
332
333```bash
334cd /workspaces/hve-core
335git pull
336```
337
338### Auto-Update on Codespace Start
339
340Add `updateContentCommand` to your devcontainer.json:
341
342```jsonc
343{
344 "updateContentCommand": "cd /workspaces/hve-core && git pull --ff-only 2>/dev/null || true"
345}
346```
347
348This runs when the Codespace starts (not on every terminal open).
349
350### Force Fresh Clone
351
352To always get the latest version on rebuild:
353
354```jsonc
355{
356 "postCreateCommand": "rm -rf /workspaces/hve-core && git clone --depth 1 https://github.com/microsoft/hve-core.git /workspaces/hve-core"
357}
358```
359
360**Warning:** This removes any local changes on every rebuild.
361
362## Troubleshooting
363
364### Agents Not Appearing
365
366**Check HVE-Core was cloned:**
367
368```bash
369ls /workspaces/hve-core/.github/agents
370```
371
372**Check postCreateCommand ran:**
373
374Look at the Codespace creation log for clone output or errors.
375
376### Clone Failed During Creation
377
378**Network issues:** Try rebuilding the Codespace.
379
380**GitHub rate limiting:** Ensure you're authenticated:
381
382```bash
383gh auth status
384```
385
386### Settings Not Applied
387
388**Check devcontainer.json paths:**
389
390Settings must use absolute paths (`/workspaces/hve-core/...`).
391
392**Verify settings in VS Code:**
393
3941. Open Command Palette (`Ctrl+Shift+P`)
3952. Type "Preferences: Open User Settings (JSON)"
3963. Check if settings are present
397
398### Codespace Rebuild Doesn't Update HVE-Core
399
400The clone command skips if the folder exists. Force update:
401
402```bash
403cd /workspaces/hve-core
404git pull
405```
406
407Or modify postCreateCommand to always pull (see Auto-Update section).
408
409## Limitations
410
411| Aspect | Status |
412|---------------------|-------------------------------------------|
413| Codespaces | ✅ Designed for this |
414| Local devcontainers | ⚠️ Works but consider other methods |
415| Team sharing | ✅ Auto-setup for all contributors |
416| Portable paths | ⚠️ Absolute paths only |
417| Version pinning | ⚠️ Modify clone command for specific tag |
418| Offline support | ❌ Requires network during creation |
419| Setup complexity | ✅ Low (just devcontainer.json) |
420
421## Version Pinning
422
423To pin to a specific version:
424
425```jsonc
426{
427 "postCreateCommand": "[ -d /workspaces/hve-core ] || git clone --depth 1 --branch v1.0.0 https://github.com/microsoft/hve-core.git /workspaces/hve-core"
428}
429```
430
431Replace `v1.0.0` with your desired version tag.
432
433## Next Steps
434
435* [Your First Workflow](../first-workflow.md) - Try HVE-Core with a real task
436* [Multi-Root Workspace](multi-root.md) - For dual local + Codespaces support
437* [Submodule](submodule.md) - For team version control
