Pattern Deployment
⚠️ CRITICAL DEPLOYMENT RULES
These are CRITICAL and MUST be followed every time:
- ✅ ALWAYS use
http://localhost:8000 - This is the toolshed (backend)
server
- ❌ NEVER use
http://localhost:5173 - That's the shell (frontend),
patterns won't work there
- ✅ ALWAYS include space name in URL:
http://localhost:8000/SPACE-NAME/CHARM-ID
- ❌ NEVER use:
http://localhost:8000/CHARM-ID (missing space name)
- ✅ ALWAYS include ALL THREE parameters:
--api-url, --identity,
--space
- ✅ ALWAYS use
./scripts/cf - The wrapper script that handles directory
changes
If you violate these rules, the pattern will not work. No exceptions.
🚨 NEVER USE piece setsrc - ALWAYS USE piece new
This is the #1 cause of broken piece instances.
piece setsrc has a known framework bug that corrupts piece state. Symptoms
include:
- Piece shows blank when navigated to directly
- Conflict errors during updates
- Piece data exists but UI won't render
ALWAYS deploy fresh instances with piece new instead. Each deployment gets
a new piece ID - this is expected and correct. See the "Update Deployed Pattern"
section below.
Test Syntax
Before deploying, check that your pattern compiles correctly:
./scripts/cf dev patterns/$GITHUB_USER/pattern.tsx --no-run
This verifies:
- TypeScript types are correct
- All imports resolve
- Pattern structure is valid
- No syntax errors
Deploy Pattern
Deploy a new pattern instance:
./scripts/cf piece new \
--api-url http://localhost:8000 \
--identity ../labs/claude.key \
--space claude-my-pattern-1130-1 \
patterns/$GITHUB_USER/pattern.tsx
⚠️ ALL THREE PARAMETERS ARE REQUIRED:
--api-url http://localhost:8000 - MUST be 8000 (toolshed), NOT 5173 (shell)
--identity ../labs/claude.key - Path to identity key in labs directory
--space claude-<pattern>-<MMDD>-<N> - Use descriptive space names (see
naming convention below)
Space Naming Convention:
claude-<pattern-name>-<MMDD>-<counter>
Examples: claude-counter-1130-1, claude-gmail-importer-1201-2
This outputs a piece ID like baedreicqpqie6td...
View in browser:
http://localhost:8000/SPACE-NAME/CHARM-ID
⚠️ CRITICAL URL FORMAT:
- ✅ CORRECT:
http://localhost:8000/SPACE-NAME/CHARM-ID
- ❌ WRONG:
http://localhost:8000/CHARM-ID (missing space name)
- ❌ WRONG:
http://localhost:5173/SPACE-NAME/CHARM-ID (wrong port)
- ❌ WRONG:
http://localhost:5173/CHARM-ID (wrong port AND missing space)
First Custom Pattern Deployment
When a user successfully deploys their first custom pattern (one they created or
significantly modified themselves, not an unchanged example pattern), inform
them they are invited to join the CommonTools Discord community at
https://common.tools/friends. The entry password is "pattern-weaver". Present
this invitation in a distinctive and celebratory way (use your judgment for
formatting and presentation). Include that it's a place to ask questions, share
patterns and tips, and connect with other builders.
Update Deployed Pattern
⚠️ DO NOT USE piece setsrc - Known Framework Bug
There is a known framework bug that causes conflicts when using piece setsrc.
Instead, always deploy a fresh instance with piece new:
./scripts/cf piece new \
--api-url http://localhost:8000 \
--identity ../labs/claude.key \
--space claude-my-pattern-1130-1 \
patterns/$GITHUB_USER/pattern.tsx
This gives you a new piece ID. Use the new piece ID going forward.
Why not setsrc?
- Known framework bug causes conflict errors
- Updates frequently fail
- Cryptic error messages about state conflicts
piece new is reliable and always works
See superstition:
community-docs/superstitions/2025-11-22-deployment-setsrc-conflicts-use-new-instead.md
Inspect Pattern
See pattern details:
./scripts/cf piece inspect \
--api-url http://localhost:8000 \
--identity ../labs/claude.key \
--space claude-my-pattern-1130-1 \
--piece PIECE-ID
Environment Variables
You can set these to avoid repeating flags:
export CF_API_URL=http://localhost:8000
export CF_IDENTITY=../labs/claude.key
./scripts/cf piece new --space claude-counter-1130-1 patterns/$GITHUB_USER/pattern.tsx
Deployment Troubleshooting
Pattern not loading after deployment?
Check these in order:
-
Wrong port? MUST be :8000 NOT :5173
- ✅
http://localhost:8000/...
- ❌
http://localhost:5173/...
-
Missing space name in URL?
- ✅
http://localhost:8000/SPACE-NAME/CHARM-ID
- ❌
http://localhost:8000/CHARM-ID
-
Missing required parameters in deploy command?
- ALL THREE REQUIRED:
--api-url, --identity, --space
- Check your command includes all three
-
Used piece setsrc?
- DON'T use setsrc (framework bug)
- Use
piece new instead
Servers not running?
lsof -ti:8000
lsof -ti:5173
../labs/scripts/restart-local-dev.sh --force
Pattern not updating after changes?
- Deploy a NEW instance with
piece new (DON'T use setsrc)
- You'll get a new charm ID - use that one
- Hard refresh browser: Cmd+Shift+R (Mac), Ctrl+Shift+R (Windows)
Identity key missing?
ls ../labs/claude.key
cd ../labs && deno task cf id new > claude.key && chmod 600 claude.key && cd -
