fixerr

Local-first, provider-agnostic error/fix memory with semantic search and smart deduplication

---

🎯 The Problem

Every developer repeatedly solves the same errors:

• port already in use after switching branches
• ModuleNotFoundError for a package that was installed
• Docker permission errors in CI/CD
• Environment-specific configuration issues

fixerr captures these errors and their fixes, then surfaces the solution automatically when the same failure reoccurs — saving you from reinventing the wheel.

✨ Key Features

🧠 Smart Error Deduplication

• Automatically detects recurring errors using deterministic fingerprints
• Tracks occurrence frequency (seen 5x) and timestamps (first/last seen)
• Upgrades lightweight Tier 1 captures to full Tier 2 records seamlessly

🔍 Hybrid Search

• Semantic search via embeddings (when AI backend available)
• Falls back to exact/error-code matching when offline
• Combines both for maximum recall and precision

🛡️ Privacy-First by Design

• 100% local: SQLite database on your machine, no telemetry
• Automatic redaction of secrets, API keys, and volatile tokens
• No account required, no server to maintain

🤖 Provider-Agnostic AI

• Default: Ollama (fully offline)
• Swap to OpenAI, Anthropic, Gemini, or OpenAI-compatible with one config
• Graceful degradation to text-only search when no AI backend available

💻 Beautiful Terminal Dashboard

• Interactive TUI built with Textual
• Search, filter, resolve/dismiss errors, copy fixes
• Recurrence badges (×<count>) and occurrence metrics
• Semantic clustering to spot your most costly error patterns

🚀 Installation

# Core (uses local Ollama by default)
pip install fixerr

# With specific AI providers
pip install fixerr[openai]        # OpenAI / OpenAI-compatible
pip install fixerr[anthropic]     # Anthropic (Claude)
pip install fixerr[gemini]        # Google Gemini
pip install fixerr[all-providers] # Everything

Requires Python 3.9+. Works without any AI provider configured (offline text matching only).

⚡ Quick Start

Manual Capture

# Capture a failing command
some-command-that-fails 2>&1 | fixerr capture -c "some-command-that-fails"

# Record the fix
fixerr resolve 1 "increased timeout in docker-compose.yml"

# Search for similar errors later
fixerr search "connection refused on startup"

Automatic Capture (Recommended)

Zsh / Bash Add to your ~/.zshrc or ~/.bashrc:

eval "$(fixerr shell-init zsh)"   # zsh
eval "$(fixerr shell-init bash)"  # bash

PowerShell Add to your PowerShell profile:

fixerr shell-init pwsh | Out-String | Invoke-Expression

Now failed commands are captured automatically — no extra step needed.

fixerr doctor       # Check AI provider status
fixerr explain 5    # Get AI explanation for error #5

🔧 How It Works

1. Capture: Errors are captured via fixerr capture, fixerr run, or automatic shell hook
2. Redact: Secrets, API keys, emails, and volatile tokens are stripped/normalized
3. Fingerprint: Deterministic hash identifies recurring errors (ignoring timestamps, paths, etc.)
4. Store: SQLite database stores one record per unique error, with occurrence count
5. Search:
   • Semantic: Cosine similarity over embeddings (when AI backend available)
   • Fallback: Jaccard token overlap over normalized text
   • Hybrid: Combines both (Phase 2)
6. Surface: When a similar error occurs, fixerr shows the most relevant past fix

📊 The Dashboard (fixerr dashboard)

Left Pane:

• Filterable, searchable error list with recurrence badges (×<count>)

Right Pane:

• Metadata (first/last seen, occurrence count)
• Full error output and applied fix
• AI explanation (when available)
• Top 3 semantically similar past errors

Patterns tab:

• Clusters errors via k-means over embeddings to spot your most time-consuming issues

Keybindings:

Key	Action
j/k or ↑/↓	Navigate error list
r	Mark selected error resolved
d	Mark selected error won't-fix
u	Reopen resolved/won't-fix error
e	Generate/show AI explanation
c	Copy fix to clipboard
s	Focus search
/	Focus filter chips
p or 1-4	Switch tabs (All/Unresolved/Resolved/Patterns)
q/Ctrl-C	Quit

🤖 AI Backends

Configure in ~/.fixerr/config.toml:

[ai]
provider = "ollama"          # ollama | openai | openai-compatible | anthropic | gemini
embed_fallback = "ollama"    # Used when provider can't embed (e.g. anthropic)

[ai.ollama]
host = "http://localhost:11434"
embed_model = "nomic-embed-text"
gen_model = "llama3"

[ai.anthropic]
api_key_env = "ANTHROPIC_API_KEY"
gen_model = "claude-haiku-4-5"

Switch providers via CLI:

fixerr config set ai.provider anthropic
fixerr config show  # See effective config (secrets masked)

💡 Embedding in Other Tools

from fixerr import ErnestClient

client = ErnestClient()

# Surface a fix for stderr text (returns None if no confident match)
fix = client.surface(stderr_text)

# Search for similar errors in a project context
recent = client.search(
    "build failed", 
    cwd="/path/to/project", 
    top_k=3
)

Wrap in try/except ImportError to make fixerr an optional dependency.

⚙️ Configuration

Environment Variables:

Variable	Purpose	Default
fixerr_CONFIG	Path to config file	~/.fixerr/config.toml
fixerr_DB	Path to SQLite store	~/.fixerr/errors.db
fixerr_SIM_THRESHOLD	Similarity cutoff for auto-surfacing	0.7
OLLAMA_HOST	Ollama daemon URL	http://localhost:11434

Tune Tier 1 auto-capture via [capture] in ~/.fixerr/config.toml:

• auto_capture: Enable/disable
• min_exit_code: Minimum exit code to consider failure
• ignore_commands: List of commands to ignore (e.g. ["cd", "git status"])
• ignore_patterns: Regex patterns to ignore
• surface_threshold: Similarity threshold for auto-surfacing
• quiet: Suppress non-essential output

🧪 Contributing

Issues and PRs welcome! To run the test suite:

# Install dev dependencies
pip install -e ".[dev,all-providers]"

# Run tests

ruff check .

Provider tests use mocks — no real API calls or Ollama instance needed.
