description: Recover context from decision graph and recent activity - USE THIS ON SESSION START

# Context Recovery
8
+
9
+
**RUN THIS AT SESSION START.** The decision graph is your persistent memory.
10
+
11
+
## Step 1: Query the Graph
12
+
13
+
```bash
14
+
# See all decisions (look for recent ones and pending status)
15
+
deciduous nodes
16
+
17
+
# Filter by current bookmark (useful for feature work)
18
+
deciduous nodes --branch $(jj log -r @ -T 'bookmarks' --no-graph 2>/dev/null | head -1)
19
+
20
+
# See how decisions connect
21
+
deciduous edges
22
+
23
+
# What commands were recently run?
24
+
deciduous commands
25
+
```
26
+
27
+
**Bookmark-scoped context**: If working on a feature bookmark, filter nodes to see only decisions relevant to this bookmark. Main bookmark nodes are tagged with `[bookmark: main]`.
28
+
29
+
## Step 1.5: Audit Graph Integrity
30
+
31
+
**CRITICAL: Check that all nodes are logically connected.**
32
+
33
+
```bash
34
+
# Find nodes with no incoming edges (potential missing connections)
35
+
deciduous edges | cut -d'>' -f2 | cut -d' ' -f2 | sort -u > /tmp/has_parent.txt
36
+
deciduous nodes | tail -n+3 | awk '{print $1}' | while read id; do
37
+
grep -q "^$id$" /tmp/has_parent.txt || echo "CHECK: $id"
38
+
done
39
+
```
40
+
41
+
**Review each flagged node:**
42
+
- Root `goal` nodes are VALID without parents
43
+
- `outcome` nodes MUST link back to their action/goal
44
+
- `action` nodes MUST link to their parent goal/decision
45
+
- `option` nodes MUST link to their parent decision
46
+
47
+
**Fix missing connections:**
48
+
```bash
49
+
deciduous link <parent_id> <child_id> -r "Retroactive connection - <reason>"
50
+
```
51
+
52
+
## Step 2: Check VCS State
53
+
54
+
```bash
55
+
jj status
56
+
jj log -n 10
57
+
jj diff --stat
58
+
```
59
+
60
+
## Step 3: Check Session Log
61
+
62
+
```bash
63
+
cat git.log | tail -30
64
+
```
65
+
66
+
## After Gathering Context, Report:
67
+
68
+
1. **Current bookmark** and pending changes
69
+
2. **Bookmark-specific decisions** (filter by bookmark if on feature bookmark)
70
+
3. **Recent decisions** (especially pending/active ones)
71
+
4. **Last actions** from jj log and command log
72
+
5. **Open questions** or unresolved observations
73
+
6. **Suggested next steps**
74
+
75
+
### Bookmark Configuration
76
+
77
+
Check `.deciduous/config.toml` for bookmark settings:
78
+
```toml
79
+
[branch]
80
+
main_branches = ["main", "master"] # Which bookmarks are "main"
81
+
auto_detect = true # Auto-detect bookmark on node creation
82
+
```
83
+
84
+
---
85
+
86
+
## REMEMBER: Real-Time Logging Required
87
+
88
+
After recovering context, you MUST follow the logging workflow:
89
+
90
+
```
91
+
EVERY USER REQUEST → Log goal/decision first
92
+
BEFORE CODE CHANGES → Log action
93
+
AFTER CHANGES → Log outcome, link nodes
94
+
BEFORE PUSH → deciduous sync
95
+
```
96
+
97
+
**The user is watching the graph live.** Log as you go, not after.
98
+
99
+
### Quick Logging Commands
100
+
101
+
```bash
102
+
# Root goal with user prompt (capture what the user asked for)
103
+
deciduous add goal "What we're trying to do" -c 90 -p "User asked: <their request>"
104
+
105
+
deciduous add action "What I'm about to implement" -c 85
106
+
deciduous add outcome "What happened" -c 95
107
+
deciduous link FROM TO -r "Connection reason"
108
+
109
+
# Capture prompt when user redirects mid-stream
110
+
deciduous add action "Switching approach" -c 85 -p "User said: use X instead"
111
+
112
+
deciduous sync # Do this frequently!
113
+
```
114
+
115
+
**When to use `--prompt`:** On root goals (always) and when user gives new direction mid-stream. Downstream nodes inherit context via edges.
116
+
117
+
---
118
+
119
+
## Focus Areas
120
+
121
+
If $ARGUMENTS specifies a focus, prioritize context for:
122
+
123
+
- **auth**: Authentication-related decisions
124
+
- **ui** / **graph**: UI and graph viewer state
125
+
- **cli**: Command-line interface changes
126
+
- **api**: API endpoints and data structures
127
+
128
+
---
129
+
130
+
## The Memory Loop
131
+
132
+
```
133
+
SESSION START
134
+
↓
135
+
Run /recover → See past decisions
136

+
## Multi-User Sync
161
+
162
+
If working in a team, check for and apply patches from teammates:
163
+
164
+
```bash
165
+
# Check for unapplied patches
166
+
deciduous diff status
167
+
168
+
# Apply all patches (idempotent - safe to run multiple times)
169
+
deciduous diff apply .deciduous/patches/*.json
170
+
171
+
# Preview before applying
172
+
deciduous diff apply --dry-run .deciduous/patches/teammate-feature.json
173
+
```
174
+
175
+
Before pushing your bookmark, export your decisions for teammates:
176
+
177
+
```bash
178
+
# Export your bookmark's decisions as a patch
179
+
BOOKMARK=$(jj log -r @ -T 'bookmarks' --no-graph 2>/dev/null | head -1)
180
+
deciduous diff export --branch "$BOOKMARK" \
181
+
-o .deciduous/patches/$(whoami)-$BOOKMARK.json
182
+
183
+
# The patch file will be tracked automatically by jj
184
+
```
185
+
186
+
## Why This Matters
187
+
188
+
- Context loss during compaction loses your reasoning
189
+
- The graph survives - query it early, query it often
190
+
- Retroactive logging misses details - log in the moment
191
+
- The user sees the graph live - show your work
192
+
- Patches share reasoning with teammates

# Decision Graph Management

+
**Log decisions IN REAL-TIME as you work, not retroactively.**
10
+
11
+
## When to Use This
12
+
13
+
| You're doing this... | Log this type | Command |
14
+
|---------------------|---------------|---------|
15
+
| Starting a new feature | `goal` **with -p** | `/decision add goal "Add user auth" -p "user request"` |
16
+
| Choosing between approaches | `decision` | `/decision add decision "Choose auth method"` |
17
+
| Considering an option | `option` | `/decision add option "JWT tokens"` |
18
+
| About to write code | `action` | `/decision add action "Implementing JWT"` |
19
+
| Noticing something | `observation` | `/decision add obs "Found existing auth code"` |
20
+
| Finished something | `outcome` | `/decision add outcome "JWT working"` |
21
+
22
+
## Quick Commands
23
+
24
+
Based on $ARGUMENTS:
25
+
26
+
### View Commands
27
+
- `nodes` or `list` -> `deciduous nodes`
28
+
- `edges` -> `deciduous edges`
29
+
- `graph` -> `deciduous graph`
30
+
- `commands` -> `deciduous commands`
31
+
32
+
### Create Nodes (with optional metadata)
33
+
- `add goal <title>` -> `deciduous add goal "<title>" -c 90`
34
+
- `add decision <title>` -> `deciduous add decision "<title>" -c 75`
35
+
- `add option <title>` -> `deciduous add option "<title>" -c 70`
36
+
- `add action <title>` -> `deciduous add action "<title>" -c 85`
37
+
- `add obs <title>` -> `deciduous add observation "<title>" -c 80`
38
+
- `add outcome <title>` -> `deciduous add outcome "<title>" -c 90`
39
+
40
+
### Optional Flags for Nodes
41
+
- `-c, --confidence <0-100>` - Confidence level
42
+
- `-p, --prompt "..."` - Store the user prompt that triggered this node
43
+
- `-f, --files "file1.rs,file2.rs"` - Associate files with this node
44
+
- `-b, --branch <name>` - jj bookmark (auto-detected by default)
45
+
- `--no-branch` - Skip bookmark auto-detection
46
+
- `--commit <hash|HEAD>` - Link to commit (use HEAD for current)
47
+
48
+
### ⚠️ CRITICAL: Link Commits to Actions/Outcomes
49
+
50
+
**After every jj commit, link it to the decision graph!**
51
+
52
+
```bash
53
+
jj commit -m "feat: add auth"
54
+
deciduous add action "Implemented auth" -c 90 --commit HEAD
55
+
deciduous link <goal_id> <action_id> -r "Implementation"
56
+
```
57
+
58
+
## CRITICAL: Capture VERBATIM User Prompts
59
+
60
+
**Prompts must be the EXACT user message, not a summary.** When a user request triggers new work, capture their full message word-for-word.
61
+
62
+
**BAD - summaries are useless for context recovery:**
63
+
```bash
64
+
# DON'T DO THIS - this is a summary, not a prompt
65
+
deciduous add goal "Add auth" -p "User asked: add login to the app"
66
+
```
67
+
68
+
**GOOD - verbatim prompts enable full context recovery:**
69
+
```bash
70
+
# Use --prompt-stdin for multi-line prompts
71
+
deciduous add goal "Add auth" -c 90 --prompt-stdin << 'EOF'
72
+
I need to add user authentication to the app. Users should be able to sign up
73
+
with email/password, and we need OAuth support for Google and GitHub. The auth
74
+
should use JWT tokens with refresh token rotation.
75
+
EOF
76
+
77
+
# Or use the prompt command to update existing nodes
78
+
deciduous prompt 42 << 'EOF'
79
+
The full verbatim user message goes here...
80
+
EOF
81
+
```
82
+
83
+
**When to capture prompts:**
84
+
- Root `goal` nodes: YES - the FULL original request
85
+
- Major direction changes: YES - when user redirects the work
86
+
- Routine downstream nodes: NO - they inherit context via edges
87
+
88
+
**Updating prompts on existing nodes:**
89
+
```bash
90
+
deciduous prompt <node_id> "full verbatim prompt here"
91
+
cat prompt.txt | deciduous prompt <node_id> # Multi-line from stdin
92
+
```
93
+
94
+
Prompts are viewable in the TUI detail panel (`deciduous tui`) and web viewer.
95
+
96
+
## Bookmark-Based Grouping
97
+
98
+
**Nodes are automatically tagged with the current jj bookmark.** This enables filtering by feature/PR.
99
+
100
+
### How It Works
101
+
- When you create a node, the current jj bookmark is stored in `metadata_json`
102
+
- Configure which bookmarks are "main" in `.deciduous/config.toml`:
103
+
```toml
104
+
[branch]
105
+
main_branches = ["main", "master"] # Bookmarks not treated as "feature bookmarks"
106
+
auto_detect = true # Auto-detect bookmark on node creation
107
+
```
108
+
- Nodes on feature bookmarks (anything not in `main_branches`) can be grouped/filtered
109
+
110
+
### CLI Filtering
111
+
```bash
112
+
# Show only nodes from specific bookmark
113
+
deciduous nodes --branch main
114
+
deciduous nodes --branch feature-auth
115
+
deciduous nodes -b my-feature
116
+
117
+
# Override auto-detection when creating nodes
118
+
deciduous add goal "Feature work" -b feature-x # Force specific bookmark
119
+
deciduous add goal "Universal note" --no-branch # No bookmark tag
120
+
```
121
+
122
+
### Web UI Bookmark Filter
123
+
The graph viewer shows a bookmark dropdown in the stats bar:
124
+
- "All bookmarks" shows everything
125
+
- Select a specific bookmark to filter all views (Chains, Timeline, Graph, DAG)
126
+
127
+
### When to Use Bookmark Grouping
128
+
- **Feature work**: Nodes created on `feature-auth` bookmark auto-grouped
129
+
- **PR context**: Filter to see only decisions for a specific PR
130
+
- **Cross-cutting concerns**: Use `--no-bookmark` for universal notes
131
+
- **Retrospectives**: Filter by bookmark to see decision history per feature
132
+
133
+
### Create Edges
134
+
- `link <from> <to> [reason]` -> `deciduous link <from> <to> -r "<reason>"`
135
+
136
+
### Sync Graph
137
+
- `sync` -> `deciduous sync`
138
+
139
+
### Multi-User Sync (Diff/Patch)
140
+
- `diff export -o <file>` -> `deciduous diff export -o <file>` (export nodes as patch)
141
+
- `diff export --nodes 1-10 -o <file>` -> export specific nodes
142
+
- `diff export --branch feature-x -o <file>` -> export nodes from branch
143
+
- `diff apply <file>` -> `deciduous diff apply <file>` (apply patch, idempotent)
144
+
- `diff apply --dry-run <file>` -> preview without applying
145
+
- `diff status` -> `deciduous diff status` (list patches in .deciduous/patches/)
146
+
- `migrate` -> `deciduous migrate` (add change_id columns for sync)
147
+
148
+
### Export & Visualization
149
+
- `dot` -> `deciduous dot` (output DOT to stdout)
150
+
- `dot --png` -> `deciduous dot --png -o graph.dot` (generate PNG)
151
+
- `dot --nodes 1-11` -> `deciduous dot --nodes 1-11` (filter nodes)
152
+
- `writeup` -> `deciduous writeup` (generate PR writeup)
153
+
- `writeup -t "Title" --nodes 1-11` -> filtered writeup
154
+
155
+
## Node Types
156
+
157
+
| Type | Purpose | Example |
158
+
|------|---------|---------|
159
+
| `goal` | High-level objective | "Add user authentication" |
160
+
| `decision` | Choice point with options | "Choose auth method" |
161
+
| `option` | Possible approach | "Use JWT tokens" |
162
+
| `action` | Something implemented | "Added JWT middleware" |
163
+
| `outcome` | Result of action | "JWT auth working" |
164
+
| `observation` | Finding or data point | "Existing code uses sessions" |
165
+
166
+
## Edge Types
167
+
168
+
| Type | Meaning |
169
+
|------|---------|
170
+
| `leads_to` | Natural progression |
171
+
| `chosen` | Selected option |
172
+
| `rejected` | Not selected (include reason!) |
173
+
| `requires` | Dependency |
174
+
| `blocks` | Preventing progress |
175
+
| `enables` | Makes something possible |
176
+
177
+
## Graph Integrity - CRITICAL
178
+
179
+
**Every node MUST be logically connected.** Floating nodes break the graph's value.
180
+
181
+
### Connection Rules
182
+
| Node Type | MUST connect to | Example |
183
+
|-----------|----------------|---------|
184
+
| `outcome` | The action/goal it resolves | "JWT working" → links FROM "Implementing JWT" |
185
+
| `action` | The decision/goal that spawned it | "Implementing JWT" → links FROM "Add auth" |
186
+
| `option` | Its parent decision | "Use JWT" → links FROM "Choose auth method" |
187
+
| `observation` | Related goal/action/decision | "Found existing code" → links TO relevant node |
188
+
| `decision` | Parent goal (if any) | "Choose auth" → links FROM "Add auth feature" |
189
+
| `goal` | Can be a root (no parent needed) | Root goals are valid orphans |
190
+
191
+
### Audit Checklist
192
+
Ask yourself after creating nodes:
193
+
1. Does every **outcome** link back to what caused it?
194
+
2. Does every **action** link to why you did it?
195
+
3. Does every **option** link to its decision?
196
+
4. Are there **dangling outcomes** with no parent action/goal?
197
+
198
+
### Find Disconnected Nodes
199
+
```bash
200
+
# List nodes with no incoming edges (potential orphans)
201
+
deciduous edges | cut -d'>' -f2 | cut -d' ' -f2 | sort -u > /tmp/has_parent.txt
202
+
deciduous nodes | tail -n+3 | awk '{print $1}' | while read id; do
203
+
grep -q "^$id$" /tmp/has_parent.txt || echo "CHECK: $id"
204
+
done
205
+
```
206
+
Note: Root goals are VALID orphans. Outcomes/actions/options usually are NOT.
207
+
208
+
### Fix Missing Connections
209
+
```bash
210
+
deciduous link <parent_id> <child_id> -r "Retroactive connection - <why>"
211
+
```
212
+
213
+
### When to Audit
214
+
- Before every `deciduous sync`
215
+
- After creating multiple nodes quickly
216
+
- At session end
217
+
- When the web UI graph looks disconnected
218
+
219
+
## Multi-User Sync
220
+
221
+
**Problem**: Multiple users work on the same codebase, each with a local `.deciduous/deciduous.db` (ignored in VCS). How to share decisions?
222
+
223
+
**Solution**: Dual-ID model. Each node has:
224
+
- `id` (integer): Local database primary key, different per machine
225
+
- `change_id` (UUID): Globally unique, stable across all databases
226
+
227
+
### Export Workflow
228
+
```bash
229
+
# Export nodes from your bookmark as a patch file
230
+
deciduous diff export --branch feature-x -o .deciduous/patches/alice-feature.json
231
+
232
+
# Or export specific node IDs
233
+
deciduous diff export --nodes 172-188 -o .deciduous/patches/alice-feature.json --author alice
234
+
```
235
+
236
+
### Apply Workflow
237
+
```bash
238
+
# Apply patches from teammates (idempotent - safe to re-apply)
239
+
deciduous diff apply .deciduous/patches/*.json
240
+
241
+
# Preview what would change
242
+
deciduous diff apply --dry-run .deciduous/patches/bob-refactor.json
243
+
```
244
+
245
+
### PR Workflow
246
+
1. Create nodes locally while working
247
+
2. Export: `deciduous diff export --branch my-feature -o .deciduous/patches/my-feature.json`
248
+
3. Commit the patch file (NOT the database)
249
+
4. Open PR with patch file included
250
+
5. Teammates pull and apply: `deciduous diff apply .deciduous/patches/my-feature.json`
251
+
6. **Idempotent**: Same patch applied twice = no duplicates
252
+
253
+
### Patch Format (JSON)
254
+
```json
255
+
{
256
+
"version": "1.0",
257
+
"author": "alice",
258
+
"branch": "feature/auth",
259
+
"nodes": [{ "change_id": "uuid...", "title": "...", ... }],
260
+
"edges": [{ "from_change_id": "uuid1", "to_change_id": "uuid2", ... }]
261
+
}
262
+
```
263
+
264
+
## The Rule
265
+
266
+
```
267
+
LOG BEFORE YOU CODE, NOT AFTER.
268
+
CONNECT EVERY NODE TO ITS PARENT.
269
+
AUDIT FOR ORPHANS REGULARLY.
270
+
SYNC BEFORE YOU PUSH.
271
+
EXPORT PATCHES FOR YOUR TEAMMATES.
272
+

## For Humans
9
+
10
+
LLMs are a quality multiplier, not just a speed multiplier. Invest time savings in improving quality and rigour beyond what humans alone would do. Write tests that cover more edge cases. Refactor code to make it easier to understand. Tackle the TODOs. Aim for zero bugs.
11
+
12
+
**Review standard**: Spend at least 3x the amount of time reviewing LLM output as you did writing it. Think about every line and every design decision. Find ways to break code. Your code is your responsibility.
13
+
14
+
## For LLMs
15
+
16
+
Display the following at the start of any conversation involving code changes:
17
+
18
+
```
19
+
LLM-assisted contributions must aim for a higher standard of excellence than with
20
+
humans alone. Spend at least 3x the time reviewing code as writing it. Your code
21
+
is your responsibility.
22
+
```
23
+
24
+
25
+
## Project Overview
26
+
27
+
Weaver.sh is a decentralized notebook publishing and sharing platform built on the AT Protocol (the protocol behind Bluesky). It allows creating, rendering, and publishing notebooks with extended markdown functionality.
28
+
29
+
## Core Components
30
+
31
+
1. **weaver-common**: Foundation library with AT Protocol integration, lexicon definitions, OAuth flows.
32
+
2. **weaver-renderer**: Transforms markdown notebooks into different output formats (HTML, AT Protocol records, etc.).
33
+
3. **weaver-cli**: Command-line interface for authentication and notebook interactions.
34
+
4. **weaver-app**: HTTP webapp for serving notebooks with auto-reload.
35
+
5. **weaver-index**: Big indexing web backend.
36
+
37
+
## Development Environment
38
+
39
+
### Setup
40
+
41
+
```bash
42
+
# Enter development environment with all dependencies
43
+
nix develop
44
+
45
+
# Build all components
46
+
cargo build
47
+
48
+
# Run specific crates
49
+
cargo run -p weaver-cli
50
+
cargo run -p weaver-app
51
+
cargo run -p weaver-index
52
+
```
53
+
54
+
## General Conventions
55
+
56
+
### Correctness Over Convenience
57
+
58
+
- Model the full error space—no shortcuts or simplified error handling.
59
+
- Handle all edge cases, including race conditions and platform differences.
60
+
- Use the type system to encode correctness constraints.
61
+
- Prefer compile-time guarantees over runtime checks where possible.
62
+
63
+
### Type System Patterns
64
+
65
+
- **Newtypes** for domain types (IDs, handles, etc.).
66
+
- **Builder patterns** for complex construction.
67
+
- **Restricted visibility**: Use `pub(crate)` and `pub(super)` liberally.
68
+
- **Non-exhaustive**: All public error types should be `#[non_exhaustive]`.
69
+
- Use Rust enums over string validation.
70
+
71
+
### Error Handling
72
+
73
+
- Use `thiserror` for error types with `#[derive(Error)]`.
74
+
- Group errors by category with an `ErrorKind` enum when appropriate.
75
+
- Provide rich error context using `miette` for user-facing errors.
76
+
- Error display messages should be lowercase sentence fragments.
77
+
78
+
### Module Organization
79
+
80
+
- Keep module boundaries strict with restricted visibility.
81
+
- Platform-specific code in separate files: `unix.rs`, `windows.rs`.
82
+
83
+
### Documentation
84
+
85
+
- Inline comments explain "why," not just "what".
86
+
- Module-level documentation explains purpose and responsibilities.
87
+
- **Always** use periods at the end of code comments.
88
+
- **Never** use title case in headings. Always use sentence case.
89
+
90
+
## Testing Practices
91
+
92
+
**CRITICAL**: Always use `cargo nextest run` to run tests. Never use `cargo test` directly.
93
+
94
+
```bash
95
+
# Run all tests
96
+
cargo nextest run
97
+
98
+
# Specific crate
99
+
cargo nextest run -p pattern-db
100
+
101
+
# With output
102
+
cargo nextest run --nocapture
103
+
104
+
# Doctests (nextest doesn't support these)
105
+
cargo test --doc
106
+
```
107
+
108
+
## Common Development Commands
109
+
110
+
### Testing
111
+
112
+
```bash
113
+
# Run all tests with nextest
114
+
cargo nextest run
115
+
116
+
# Run specific tests
117
+
cargo nextest run -p weaver-common
118
+
```
119
+
120
+
### Code Quality
121
+
122
+
```bash
123
+
# Run linter
124
+
cargo clippy -- --deny warnings
125
+
126
+
# Format code
127
+
cargo fmt
128
+
129
+
# Verify dependencies
130
+
cargo deny check
131
+
```
132
+
133
+
### Lexicon Generation
134
+
135
+
The project uses custom AT Protocol lexicons defined in JSON format. To generate Rust code from these definitions:
136
+
137
+
```bash
138
+
nix run ../jacquard
139
+
140
+
### Building with Nix
141
+
142
+
```bash
143
+
# Run all checks (clippy, fmt, tests)
144
+
nix flake check
145
+
146
+
# Build specific packages
147
+
nix build .#weaver-cli
148
+
nix build .#weaver-app
149
+
```
150
+
151
+
152
+
## Architecture
153
+
154
+
### Data Flow
155
+
156
+
1. Markdown notebooks are parsed and processed by weaver-renderer
157
+
2. Content can be rendered as static sites or published to AT Protocol PDSes
158
+
3. Authentication with AT Protocol servers happens via OAuth
159
+
160
+
### Key Components
161
+
162
+
- **WeaverAgent**: Manages connections to AT Protocol Personal Data Servers (PDS)
163
+
- **Notebook Structure**: Books, chapters, entries with extended markdown
164
+
- **Renderer**: Processes markdown with extended features (wiki links, embeds, math)
165
+
- **AT Protocol Lexicons**: Custom data schemas extending the protocol for notebooks
166
+
167
+
### Authentication Flow
168
+
169
+
1. CLI initiates OAuth flow with a PDS
170
+
2. Local OAuth server handles callbacks on port 4000
171
+
3. Tokens are stored in the local filesystem
172
+
173
+
## Feature Flags
174
+
175
+
- **dev**: Enables development-specific features
176
+
- **native**: Configures OAuth for native clients
177
+
178
+
## Working with Jacquard
179
+
180
+
This project uses Jacquard, a zero-copy AT Protocol library for Rust. **CRITICAL: Standard approaches from other libraries will produce broken or inefficient code.**
181
+
182
+
**ALWAYS use the working-with-jacquard skill** when working with AT Protocol types, XRPC calls, or identity resolution.
183
+
184
+
Key patterns to internalize:
185
+
- **NEVER use `for<'de> Deserialize<'de>` bounds** - this breaks ALL Jacquard types
186
+
- Use `Did::new()`, `Handle::new_static()`, etc. - **never `FromStr::parse()`**
187
+
- Use `Data<'a>` instead of `serde_json::Value`
188
+
- Use `.into_output()` when returning from functions, `.parse()` for immediate processing
189
+
- Derive `IntoStatic` on all custom types with lifetimes
190
+
191
+
See `~/.claude/skills/working-with-jacquard/SKILL.md` for complete guidance.
192
+
193
+
## Commit Message Style
194
+
195
+
```
196
+
[crate-name] brief description
197
+
```
198
+
199
+
Examples:
200
+
- `[pattern-core] add supervisor coordination pattern`
201
+
- `[pattern-db] fix FTS5 query escaping`
202
+
- `[meta] update MSRV to Rust 1.83`
203
+
204
+
### Conventions
205
+
206
+
- Use `[meta]` for cross-cutting concerns (deps, CI, workspace config).
207
+
- Keep descriptions concise but descriptive.
208
+
- **Atomic commits**: Each commit should be a logical unit of change.
209
+
- **Bisect-able history**: Every commit must build and pass all checks.
210
+
- **Separate concerns**: Format fixes and refactoring separate from features.

# Dioxus Dependency
6
+
7
+
You can add Dioxus to your `Cargo.toml` like this:
8
+
9
+
```toml
10
+
[dependencies]
11
+
dioxus = { version = "0.7.0" }
12
+
13
+
[features]
14
+
default = ["web", "webview", "server"]
15
+
web = ["dioxus/web"]
16
+
webview = ["dioxus/desktop"]
17
+
server = ["dioxus/server"]
18
+
```
19
+
20
+
# Launching your application
21
+
22
+
You need to create a main function that sets up the Dioxus runtime and mounts your root component.
23
+
24
+
```rust
25
+
use dioxus::prelude::*;
26
+
27
+
fn main() {
28
+
dioxus::launch(App);
29
+
}
30
+
31
+
#[component]
32
+
fn App() -> Element {
33
+
rsx! { "Hello, Dioxus!" }
34
+
}
35
+
```
36
+
37
+
Then serve with `dx serve`:
38
+
39
+
```sh
40
+
curl -sSL http://dioxus.dev/install.sh | sh
41
+
dx serve
42
+
```
43
+
44
+
# UI with RSX
45
+
46
+
```rust
47
+
rsx! {
48
+
div {
49
+
class: "container", // Attribute
50
+
color: "red", // Inline styles
51
+
width: if condition { "100%" }, // Conditional attributes
52
+
"Hello, Dioxus!"
53
+
}
54
+
// Prefer loops over iterators
55
+
for i in 0..5 {
56
+
div { "{i}" } // use elements or components directly in loops
57
+
}
58
+
if condition {
59
+
div { "Condition is true!" } // use elements or components directly in conditionals
60
+
}
61
+
62
+
{children} // Expressions are wrapped in brace
63
+
{(0..5).map(|i| rsx! { span { "Item {i}" } })} // Iterators must be wrapped in braces
64
+
}
65
+
```
66
+
67
+
# Assets
68
+
69
+
The asset macro can be used to link to local files to use in your project. All links start with `/` and are relative to the root of your project.
70
+
71
+
```rust
72
+
rsx! {
73
+
img {
74
+
src: asset!("/assets/image.png"),
75
+
alt: "An image",
76
+
}
77
+
}
78
+
```
79
+
80
+
## Styles
81
+
82
+
The `document::Stylesheet` component will inject the stylesheet into the `<head>` of the document
83
+
84
+
```rust
85
+
rsx! {
86
+
document::Stylesheet {
87
+
href: asset!("/assets/styles.css"),
88
+
}
89
+
}
90
+
```
91
+
92
+
# Components
93
+
94
+
Components are the building blocks of apps
95
+
96
+
* Component are functions annotated with the `#[component]` macro.
97
+
* The function name must start with a capital letter or contain an underscore.
98
+
* A component re-renders only under two conditions:
99
+
1. Its props change (as determined by `PartialEq`).
100
+
2. An internal reactive state it depends on is updated.
101
+
102
+
```rust
103
+
#[component]
104
+
fn Input(mut value: Signal<String>) -> Element {
105
+
rsx! {
106
+
input {
107
+
value,
108
+
oninput: move |e| {
109
+
*value.write() = e.value();
110
+
},
111
+
onkeydown: move |e| {
112
+
if e.key() == Key::Enter {
113
+
value.write().clear();
114
+
}
115
+
},
116
+
}
117
+
}
118
+
}
119
+
```
120
+
121
+
Each component accepts function arguments (props)
122
+
123
+
* Props must be owned values, not references. Use `String` and `Vec<T>` instead of `&str` or `&[T]`.
124
+
* Props must implement `PartialEq` and `Clone`.
125
+
* To make props reactive and copy, you can wrap the type in `ReadOnlySignal`. Any reactive state like memos and resources that read `ReadOnlySignal` props will automatically re-run when the prop changes.
126
+
127
+
# State
128
+
129
+
A signal is a wrapper around a value that automatically tracks where it's read and written. Changing a signal's value causes code that relies on the signal to rerun.
130
+
131
+
## Local State
132
+
133
+
The `use_signal` hook creates state that is local to a single component. You can call the signal like a function (e.g. `my_signal()`) to clone the value, or use `.read()` to get a reference. `.write()` gets a mutable reference to the value.
134
+
135
+
Use `use_memo` to create a memoized value that recalculates when its dependencies change. Memos are useful for expensive calculations that you don't want to repeat unnecessarily.
136
+
137
+
```rust
138
+
#[component]
139
+
fn Counter() -> Element {
140
+
let mut count = use_signal(|| 0);
141
+
let mut doubled = use_memo(move || count() * 2); // doubled will re-run when count changes because it reads the signal
142
+
143
+
rsx! {
144
+
h1 { "Count: {count}" } // Counter will re-render when count changes because it reads the signal
145
+
h2 { "Doubled: {doubled}" }
146
+
button {
147
+
onclick: move |_| *count.write() += 1, // Writing to the signal rerenders Counter
148
+
"Increment"
149
+
}
150
+
button {
151
+
onclick: move |_| count.with_mut(|count| *count += 1), // use with_mut to mutate the signal
152
+
"Increment with with_mut"
153
+
}
154
+
}
155
+
}
156
+
```
157
+
158
+
## Context API
159
+
160
+
The Context API allows you to share state down the component tree. A parent provides the state using `use_context_provider`, and any child can access it with `use_context`
161
+
162
+
```rust
163
+
#[component]
164
+
fn App() -> Element {
165
+
let mut theme = use_signal(|| "light".to_string());
166
+
use_context_provider(|| theme); // Provide a type to children
167
+
rsx! { Child {} }
168
+
}
169
+
170
+
#[component]
171
+
fn Child() -> Element {
172
+
let theme = use_context::<Signal<String>>(); // Consume the same type
173
+
rsx! {
174
+
div {
175
+
"Current theme: {theme}"
176
+
}
177
+
}
178
+
}
179
+
```
180
+
181
+
# Async
182
+
183
+
For state that depends on an asynchronous operation (like a network request), Dioxus provides a hook called `use_resource`. This hook manages the lifecycle of the async task and provides the result to your component.
184
+
185
+
* The `use_resource` hook takes an `async` closure. It re-runs this closure whenever any signals it depends on (reads) are updated
186
+
* The `Resource` object returned can be in several states when read:
187
+
1. `None` if the resource is still loading
188
+
2. `Some(value)` if the resource has successfully loaded
189
+
190
+
```rust
191
+
let mut dog = use_resource(move || async move {
192
+
// api request
193
+
});
194
+
195
+
match dog() {
196
+
Some(dog_info) => rsx! { Dog { dog_info } },
197
+
None => rsx! { "Loading..." },
198
+
}
199
+
```
200
+
201
+
# Routing
202
+
203
+
All possible routes are defined in a single Rust `enum` that derives `Routable`. Each variant represents a route and is annotated with `#[route("/path")]`. Dynamic Segments can capture parts of the URL path as parameters by using `:name` in the route string. These become fields in the enum variant.
204
+
205
+
The `Router<Route> {}` component is the entry point that manages rendering the correct component for the current URL.
206
+
207
+
You can use the `#[layout(NavBar)]` to create a layout shared between pages and place an `Outlet<Route> {}` inside your layout component. The child routes will be rendered in the outlet.
208
+
209
+
```rust
210
+
#[derive(Routable, Clone, PartialEq)]
211
+
enum Route {
212
+
#[layout(NavBar)] // This will use NavBar as the layout for all routes
213
+
#[route("/")]
214
+
Home {},
215
+
#[route("/blog/:id")] // Dynamic segment
216
+
BlogPost { id: i32 },
217
+
}
218
+
219
+
#[component]
220
+
fn NavBar() -> Element {
221
+
rsx! {
222
+
a { href: "/", "Home" }
223
+
Outlet<Route> {} // Renders Home or BlogPost
224
+
}
225
+
}
226
+
227
+
#[component]
228
+
fn App() -> Element {
229
+
rsx! { Router::<Route> {} }
230
+
}
231
+
```
232
+
233
+
```toml
234
+
dioxus = { version = "0.7.0", features = ["router"] }
235
+
```
236
+
237
+
# Fullstack
238
+
239
+
Fullstack enables server rendering and ipc calls. It uses Cargo features (`server` and a client feature like `web`) to split the code into a server and client binaries.
240
+
241
+
```toml
242
+
dioxus = { version = "0.7.0", features = ["fullstack"] }
243
+
```
244
+
245
+
## Server Functions
246
+
247
+
Use the `#[post]` / `#[get]` macros to define an `async` function that will only run on the server. On the server, this macro generates an API endpoint. On the client, it generates a function that makes an HTTP request to that endpoint.
248
+
249
+
```rust
250
+
#[post("/api/double/:path/&query")]
251
+
async fn double_server(number: i32, path: String, query: i32) -> Result<i32, ServerFnError> {
252
+
tokio::time::sleep(std::time::Duration::from_secs(1)).await;
253
+
Ok(number * 2)
254
+
}
255
+
```
256
+
257
+
## Hydration
258
+
259
+
Hydration is the process of making a server-rendered HTML page interactive on the client. The server sends the initial HTML, and then the client-side runs, attaches event listeners, and takes control of future rendering.
260
+
261
+
### Errors
262
+
The initial UI rendered by the component on the client must be identical to the UI rendered on the server.
263
+
264
+
* Use the `use_server_future` hook instead of `use_resource`. It runs the future on the server, serializes the result, and sends it to the client, ensuring the client has the data immediately for its first render.
265
+
* Any code that relies on browser-specific APIs (like accessing `localStorage`) must be run *after* hydration. Place this code inside a `use_effect` hook.
