Odoo Code Tracer

Use this skill to map how Odoo code actually executes. Trace only what you can verify in code. If a path is uncertain, mark it as uncertain and explain what evidence is missing.

First Move

Identify the starting point:

• HTTP route or controller
• form/list button action
• server action or automated action
• cron job
• ORM method called by another addon
• compute, onchange, constraint, inverse, or create/write/unlink hook
• report render
• OWL/web client action calling backend code
• external webhook or integration callback

Detect the target Odoo version. If a version-specific reference exists, consult it before tracing version-sensitive behavior:

• Odoo 17: odoo-17.0
• Odoo 18: odoo-18.0
• Odoo 19: odoo-19.0
• Odoo 20: odoo-20.0

If $ODOO_SOURCE is set, inspect local framework code for controller dispatch, ORM behavior, decorators, web client actions, assets, tests, and version-specific execution details.

Tracing Process

1. Locate the entry point with file and line reference.
2. Follow the direct method call chain.
3. Follow inheritance and super() calls through parent implementations.
4. Check decorators and implicit triggers: @api.depends, @api.constrains, @api.onchange, inverse methods, @api.ondelete, create/write/unlink overrides.
5. Follow XML wiring: buttons, actions, menus, reports, cron records, server actions, and external IDs.
6. Follow frontend wiring when relevant: asset bundle, JS module, registry entry, service call, RPC/ORM call, template event.
7. Record database operations: search, browse, read, read_group, create, write, unlink, direct SQL, savepoints, locks.
8. Record side effects: chatter, emails, notifications, activities, reports, attachments, external API calls, queue jobs, bus events.
9. Record security checks: auth mode, ACLs, record rules, groups, domains, company filters, sudo() boundaries.
10. Mark exit points and returned actions/data.

What To Watch For

• N+1 queries from searches, browses, reads, creates, writes, or unlinks inside loops.
• Hidden side effects from computed fields, constraints, onchange methods, mail mixins, activities, and automation.
• Unsafe sudo() that bypasses ownership, company, portal, or public-user boundaries.
• Fragile XML linkage through renamed methods, missing external IDs, or version-specific view syntax.
• Transaction hazards from caught database exceptions without savepoints.
• Business rules split across views, onchanges, controllers, and scheduled actions.

Common Entry Patterns

Entry Type	Where To Look	Follow Next
Controller	controllers/*.py, @http.route	request env, auth, params, model calls
Button	XML <button name="..." type="object">	model method, overrides, returned action
Cron	XML/data ir.cron record	model method, batching, side effects
Server action	XML/data ir.actions.server	model, code block, target records
Compute	field compute="...", @api.depends	dependencies, store behavior, recompute path
Onchange	@api.onchange, form view fields	UI-only behavior, persisted equivalent
Constraint	@api.constrains, SQL constraints	validation path and exception behavior
Report	ir.actions.report, QWeb template	access, render context, attachments
OWL/RPC	static/src, services, registries	backend route/model method

Output Format

## Code Execution Trace

### Entry Point
- Type: Controller / Button / Cron / Server action / Compute / Onchange / Constraint / Report / OWL / Other
- Location: `path/to/file.py:XX`
- Trigger: user action, scheduler, external request, field access, module update, etc.

### Flow
```text
ENTRY: `path/to/file.xml:XX` button/action/route
-> `models/foo.py:42` Foo.action_do_thing()
   -> `models/foo.py:63` Foo._prepare_values()
   -> `models/bar.py:18` Bar.create()
   -> side effect: message_post()
RETURN: `ir.actions.act_window`
```

### Detailed Trace
- `path/to/file.py:XX` method name, decorators, inputs, key branches.
- `path/to/parent.py:XX` parent implementation reached via `super()`.
- `path/to/data.xml:XX` cron/action/report/XML ID involved.

### Database Operations
- `search`: model/domain/count if known.
- `create/write/unlink`: model/count if known.
- Direct SQL/savepoints/locks: state exact location.
- N+1 risk: yes/no/uncertain with reason.

### Security Notes
- Auth mode, ACL/record-rule expectations, groups, company behavior, `sudo()` boundaries.

### Side Effects
- Emails, chatter, activities, attachments, reports, external calls, queue jobs, bus events.

### Uncertain Paths
- State what could not be proven and what file/source would resolve it.

Response Rules

• Always include file/line references for traced code.
• Trace inheritance and super() explicitly.
• Do not assume a framework path if local source is available; inspect it.
• Do not run Odoo commands that touch a database or service without user confirmation.
• If the trace reveals review findings, compose with odoo-code-review.
