# better-logging

This skill turns key runtime operations into queryable outcome records. Use it when scattered logs make failures, latency, or regressions hard to trace.

## What it does

better-logging treats an operation boundary as the unit of instrumentation. It covers HTTP handlers, tRPC procedures, IPC commands, queue consumers, cron jobs, startup actions, and background work. A record begins at entry, gains context during execution, and is finalized in `finally`, so both successful and failed runs produce an outcome.

The package includes `scripts/audit_queryable_outcomes.py`, which scans a repository for operation boundaries, correlation fields, and existing durable signals. `references/event-schema.md` defines the event shape, while separate references cover Electron and Node runtimes. `references/rollout-and-queries.md` describes how to test the resulting data. Missing `request_id`, `operation_id`, or `session_id` weakens every later query.

The skill recommends a local table, operational event store, or queryable analytics sink instead of ephemeral console output. Secrets, tokens, raw prompts, and unnecessary URL data should be redacted or hashed. Start the audit with `python3 scripts/audit_queryable_outcomes.py --root . --format markdown`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add biw/skills --skill better-logging -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/better-logging/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/better-logging/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add biw/skills --skill better-logging -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/better-logging/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add biw/skills --skill better-logging -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/better-logging/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install biw/skills better-logging
```

2. **Manually: put the files in place**
- File: `.github/skills/better-logging/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add biw/skills --skill better-logging -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/biw/skills --path skills/better-logging
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/better-logging/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add biw/skills --skill better-logging -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/biw/skills/tree/HEAD/skills/better-logging/SKILL.md

## When to use it
- map operation boundaries across a repository
- capture success and failure in one durable event
- add duration, retry count, and stable error codes
- test whether events answer failure and latency questions

## Example prompts
- Audit this repository and identify the HTTP handlers, queue consumers, and startup flows that need instrumentation.
- Design an event schema for the payment operation and wrap it so the outcome is persisted from `finally`.
- Review the current events and check whether they support failure, latency, and regression queries.

# Better Logging

Turn important operations into durable structured records that answer "what happened?" with one query instead of a trail of log lines.

Treat the unit of instrumentation as an operation owned by the runtime, not as individual log statements sprinkled through the codebase.

## Quick Start

- Run the audit script first:

```bash
python3 scripts/audit_queryable_outcomes.py \
  --root . \
  --format markdown
```

Run the bundled `scripts/audit_queryable_outcomes.py` from this skill directory. If needed, resolve the directory containing this `SKILL.md` and pass the script path explicitly.

- Read exactly one runtime reference before changing code:
  - Electron, tRPC, IPC, background desktop jobs: `references/runtime-patterns-electron.md`
  - Node HTTP apps and workers: `references/runtime-patterns-node.md`
- Use `references/event-schema.md` to define the canonical event shape before writing middleware or wrappers.
- Instrument the top 3 user-critical operations first. Do not start with every route or command in the repo.

## Workflow

1. Inventory operation boundaries.
   Transport boundaries usually matter most: HTTP handlers, tRPC procedures, IPC commands, queue consumers, cron jobs, startup flows.
   Treat low-level helper functions as enrichment points, not as the canonical operation.
2. Choose the operation record shape.
   Read `references/event-schema.md`.
   Lock required fields first: operation name, type, timestamps, duration, success, stable error code, correlation ID, version metadata.
3. Add one wrapper at the boundary.
   Start the record at entry.
   Enrich while the operation runs.
   Finalize and persist in `finally` so success and failure paths both emit an outcome.
4. Add domain context that improves debugging.
   Include actor, resource, trigger, rollout flags, retry count, and version data when available.
   Omit fields that are only interesting for local debugging or that contain secrets.
5. Persist or emit the result durably.
   Prefer a local table, operational event store, or queryable analytics sink.
   Do not rely on ephemeral console logs or in-memory buffers for critical outcomes.
6. Verify with real questions.
   Read `references/rollout-and-queries.md`.
   If the new shape cannot answer failure, latency, and regression questions quickly, the instrumentation is still too thin.
