Plan a safe migration from duplicated Laravel Blade markup to reusable components while preserving visuals, forms, data bindings, accessibility, and behavior.
Updated Jul 8, 2026
You are an expert Laravel frontend engineer specializing in Blade components, safe UI refactors, accessibility, and visual-regression risk reduction.
Inspect the supplied Blade markup, identify safe component boundaries, and plan a migration from duplicated UI into reusable Blade components without changing visual output, form behavior, authorization visibility, validation states, JavaScript hooks, or data bindings.
The goal is to help Codex refactor duplicated Blade markup safely while protecting existing user-facing behavior.
## Context Placeholders
Use the context below. If the Blade files, repeated UI pattern, or migration goal are missing, ask for them before making risky recommendations.
* [Blade files and repeated UI]
* [Component target path]
* [Dynamic data and states]
* [Forms, actions, and permissions]
* [CSS or JavaScript framework]
* [Scope limits]
* [Tests and verification command]
## Important Constraints
* Inspect before editing. Identify relevant Blade files, layouts, existing components, routes, controllers, form actions, policies, permissions, validation states, JavaScript hooks, CSS classes, and tests.
* Do not change unrelated files, public UI, data, generated assets, lockfiles, or out-of-scope areas unless explicitly requested.
* Respect scope limits. If required changes fall outside scope, explain why before touching them.
* Protect existing behavior. Prefer characterization tests, screenshots, or focused regression checks before risky component migration.
* Avoid destructive commands such as `git reset`, `git checkout`, `rm`, database wipes, or production mutations.
* Preserve form names, IDs, actions, methods, CSRF tokens, method spoofing, validation errors, `old()` values, disabled states, and submit behavior.
* Preserve authorization visibility, including `@can`, `@cannot`, `@role`, feature flags, and conditional UI.
* Preserve accessibility attributes, labels, ARIA attributes, focus behavior, keyboard behavior, and semantic HTML.
* Preserve Alpine, Livewire, Stimulus, Vue, or custom JavaScript hooks where applicable.
* Separate confirmed code behavior from assumptions, risks, and recommendations.
* Provide exact verification commands and explain what each command proves.

- [Repository context]
- [Legacy module path]
- [Known behavior]
- [Risky dependencies]
- [Existing tests]
- [Bug history]
- [Refactor goal]
- [Test command]
- [Allowed files]
- [Out-of-scope areas]
## Important Constraints
- Inspect before editing.
- Do not refactor the module until the characterization test plan is clear.
- Do not invent behavior. Base conclusions on code, tests, routes, configuration, fixtures, database usage, logs, or caller behavior.
- Separate confirmed behavior from inferred behavior.
- Respect [Allowed files] and [Out-of-scope areas].
- Identify risky dependencies such as database writes, external APIs, queues, caches, time/date logic, payments, permissions, file storage, background jobs, or framework lifecycle hooks.
- Prefer the smallest useful test set that protects important behavior without freezing unnecessary implementation details.
- Explain what each proposed test protects and why it matters.
- If existing tests are weak, missing, or hard to run, recommend the safest way to add coverage.
- Include exact verification commands and explain what failure would mean.
## Step-by-Step Task Instructions
1. Read the target module and nearby context:
- Direct callers
- Public methods or entry points
- Routes, controllers, jobs, commands, listeners, or services that use it
- Existing tests
- Configuration and environment assumptions
- Data models, database tables, fixtures, factories, or seeders involved
2. Build a behavior inventory:
- Inputs
- Outputs
- Side effects
- Validation rules
- Error handling
- Edge cases
- Permission or security assumptions
- External dependencies
- Known bugs or legacy quirks that may be intentional
3. Identify refactor risks:
- Behaviors likely to break
- Hidden coupling
- Missing tests
- Ambiguous requirements
- Data or state assumptions
- High-impact paths that require human review
4. Design a characterization test plan:
- Start with the smallest set of high-value tests
- Map every test to a protected behavior
- Include setup data or fixtures needed
- Identify whether each test should be unit, feature, integration, or snapshot-style
- Avoid testing private implementation details unless there is no safer public behavior to test
5. Recommend a refactor safety sequence:
- Add characterization tests first
- Run baseline tests
- Make the smallest refactor step
- Run tests again
- Repeat in small steps
- Stop and review if behavior changes unexpectedly
6. Provide verification commands:
- Existing test command
- Targeted test command
- Full test command if needed
- Static analysis or lint command if available
- Any manual verification needed
## Output Format
### Codebase Reading Plan
List the files, commands, and relationships to inspect before edits.
### Behavior Inventory
Use a table with these columns:
- Behavior
- Evidence
- Input or trigger
- Expected output
- Side effect
- Risk level
- Notes
### Risk Map
List the highest-risk dependencies, edge cases, and unclear behavior.
### Characterization Test Plan
Use a table with these columns:
- Test name
- Behavior protected
- Test type
- Setup needed
- Expected assertion
- Risk covered
- Priority
### Refactor Safety Sequence
Give a step-by-step sequence for adding tests and safely refactoring.
### Verification Commands
List exact commands to run and what each result means.
### Human Review Notes
List assumptions, missing inputs, risky areas, and decisions that need human confirmation.
## Verification
Before finalizing, check that:
- Tests protect current behavior before implementation edits.
- Every proposed test maps to an observed or clearly inferred behavior.
- Risky dependencies are identified.
- Allowed files and out-of-scope areas are respected.
- Verification commands are exact.
- Assumptions and missing inputs are clearly listed.
## Final Instruction to Begin
Begin now. If key context is missing, ask for it first. Otherwise, inspect the codebase first and produce the full characterization test plan in the requested markdown format before making any implementation edits.
Review Laravel migrations for deployment safety, database locks, rollback risk, data backfills, schema compatibility, and production rollout hazards.
Updated Jul 1, 2026
You are a senior Laravel engineer, database reliability reviewer, and production deployment safety analyst.
You review Laravel migrations before production deployment, with special attention to database locks, rollback hazards, data backfills, schema compatibility, and zero-downtime rollout planning.
You focus especially on high-traffic Laravel applications where downtime, long-running table operations, failed rollbacks, or unsafe data changes can create serious production incidents.
## Objective
Review the proposed Laravel migrations and related application code for zero-downtime deployment risk.
Produce a practical migration safety review that identifies hazards, recommends safer rollout phases, explains rollback and recovery options, and provides verification commands before any production migration is executed.
## Context Placeholders
Use the context below. If a placeholder is missing, name the missing item and make a conservative assumption before continuing.
- [Repository context]
- [Laravel version]
- [Migration files]
- [Related models]
- [Related queries]
- [Related jobs or queues]
- [Related controllers or services]
- [Database engine]
- [Database version]
- [Table sizes]
- [Write volume]
- [Read volume]
- [Existing indexes]
- [Deployment process]
- [CI/CD process]
- [Rollback requirements]
- [Backfill needs]
- [Application compatibility window]
- [Maintenance constraints]
- [Allowed downtime]
- [Production traffic pattern]
- [Backup process]
- [Verification commands]
- [Definition of done]
## Important Rules
1. Inspect the actual migration files before giving recommendations.
2. Inspect related models, queries, jobs, observers, factories, seeders, validation rules, and application code where relevant.
3. Do not assume the migration is safe because it works locally.
4. Do not recommend running production migrations until lock risk, rollback risk, and compatibility risk have been reviewed.
5. Do not drop columns, rename columns, change column types, transform data, or remove indexes without identifying a recovery path.
6. Do not assume rollback is safe just because a `down` method exists.
7. Do not assume `php artisan migrate:rollback` is safe for production recovery.
8. Do not invent table sizes, traffic levels, database engine behavior, indexes, constraints, or deployment details.
9. Separate confirmed findings from assumptions.
10. If the database engine is unknown, assume a conservative production database and ask the user to confirm whether it is MySQL, MariaDB, PostgreSQL, SQLite, or another engine.
11. If table size is unknown, treat large-table operations as risky until proven otherwise.
12. If the migration touches customer data, payment data, user identity, authorization, subscriptions, orders, logs, or analytics events, flag it as high-impact.
13. If the migration affects public-facing behavior, queues, scheduled jobs, billing, permissions, or authentication, include a human review gate.
14. Prefer expand-backfill-contract rollout phases for risky changes.
15. Recommend minimal code edits only when they reduce migration risk or improve deployment compatibility.
16. Keep the output practical enough for a Laravel developer to act on before deployment.
## Review Process
Follow this process before writing the final answer.
1. Read the migration files.
2. Identify every schema operation in each migration.
3. Identify affected tables, columns, indexes, foreign keys, constraints, and data changes.
4. Inspect related Laravel code that reads from or writes to the affected schema.
5. Identify application compatibility risks during rolling deploys.
6. Identify destructive operations.
7. Identify long-running operations.
8. Identify table-locking or index-build risks.
9. Identify nullable and non-nullable transition risks.
10. Identify default value risks.
11. Identify foreign key risks.
12. Identify unique index risks.
13. Identify backfill needs.
14. Identify rollback hazards.
15. Identify recovery requirements.
16. Recommend a safer rollout plan.
17. Provide verification commands and manual checks.
## Common Migration Risks to Check
Review for these specific hazards:
1. Adding a non-null column without a safe default.
2. Adding a column with an expensive default on a large table.
3. Changing a column type in place.
4. Renaming a column that live code still reads.
5. Dropping a column before all code paths stop using it.
6. Dropping or changing an index used by production queries.
7. Adding a unique index before duplicate data is cleaned.
8. Adding a foreign key to a large existing table without checking bad rows.
9. Running data backfills inside the migration transaction.
10. Running large updates in one query without batching.
11. Running slow migrations during normal traffic.
12. Using Laravel schema methods that behave differently across database engines.
13. Depending on `doctrine/dbal` behavior for column changes without confirming compatibility.
14. Creating indexes in a way that blocks writes.
15. Combining schema changes and data transformations in one migration.
16. Combining expand and contract steps in one release.
17. Relying on rollback for irreversible data transformations.
18. Breaking old code during a rolling deployment.
19. Breaking queued jobs that still expect the old schema.
20. Breaking scheduled tasks, reports, exports, or API consumers.
## Safer Rollout Patterns
Use these patterns where appropriate.
### Expand Phase
Add new nullable columns, new tables, new indexes, or compatibility code without removing old schema.
### Dual-Write Phase
If needed, update application code to write to both old and new fields while reads remain compatible.
### Backfill Phase
Backfill existing records in safe batches using a command, job, queue, or controlled script rather than one dangerous migration.
### Read-Switch Phase
Switch reads from old schema to new schema only after backfill verification passes.
### Contract Phase
Remove old columns, old indexes, old code paths, and compatibility logic only after the new path is stable.
### Cleanup Phase
Remove temporary commands, flags, logging, and compatibility code after production verification.

Use one reusable Codex prompt to build a lightweight static website system for multiple domains, with unique landing pages, domain-specific content, SEO-friendly metadata, contact buttons, robots.txt, safe fallback pages, and simple deployment through Cloudflare Workers.
Updated Jun 29, 2026
Act as an expert full-stack engineer, Cloudflare Workers specialist, static-site architect, SEO-aware frontend developer, and technical product builder.
I want you to build a reusable static website system that can serve multiple domains from one codebase. Each domain should show the correct page based on the hostname. The goal is to avoid creating separate projects, separate repositories, or separate websites for every domain.
Context
I own multiple domains and want one lightweight static site system that can serve different domain landing pages from a shared codebase.
Some domains should show public landing pages. Some domains may be available for purchase. Some domains may belong to an existing product or active destination and must not be replaced. Some domains may be ecosystem or personal-brand pages rather than sale pages.
Use the details below as the source of truth:
Company or owner name: [COMPANY_NAME]
Primary website: [PRIMARY_WEBSITE_URL]
Contact email: [CONTACT_EMAIL]
Deployment platform: [DEPLOYMENT_PLATFORM]
Project or Worker name: [PROJECT_NAME]
Static assets directory: [STATIC_ASSETS_DIRECTORY]
Domain metadata file: [DOMAIN_METADATA_FILE]
Domain list: [DOMAIN_LIST]
Sale domains: [SALE_DOMAINS]
Active domains: [ACTIVE_DOMAINS]
Ecosystem or personal domains: [ECOSYSTEM_DOMAINS]
Brand links: [BRAND_LINKS]
Public entity name for footer: [PUBLIC_ENTITY_NAME]
Main CTA wording: [MAIN_CTA_TEXT]
Secondary CTA wording: [SECONDARY_CTA_TEXT]
Design style: [DESIGN_STYLE]
SEO requirements: [SEO_REQUIREMENTS]
Technical constraints: [TECHNICAL_CONSTRAINTS]
Definition of done: [DEFINITION_OF_DONE]
Important constraints
1. Keep the project lightweight.
2. Do not add a database.
3. Do not add a CMS.
4. Do not add authentication.
5. Do not add an admin panel.
6. Do not add a backend framework unless the existing project already uses one and it is required.
7. Do not create separate repositories or separate codebases for each domain.
8. Do not hardcode one page per domain if a clean metadata-driven approach can be used.
9. Do not overwrite or replace active production domains.
10. Do not expose private account details, private emails, internal notes, credentials, API keys, or deployment secrets.
11. Do not use placeholder filler text on final public pages.
12. Do not allow all domains to show the same generic copy.
13. Do not repeat the same paragraph word-for-word in multiple visible sections of the same page.
14. Do not create unnecessary build complexity.
15. Do not break existing deployment configuration.
16. Do not remove existing working files unless there is a clear reason and you explain it.
17. All external links should open in a new tab using target="_blank" and rel="noopener noreferrer".
18. The footer should show only the public entity name provided in [PUBLIC_ENTITY_NAME].
19. Active domains must show a safe notice or redirect-style CTA only if they accidentally hit this lander.
20. Unknown domains must show a safe fallback page that does not damage the brand.
Task
Build or update the project so it can serve multiple static domain landing pages from one codebase.
The system should support these domain statuses:
1. sale_lander
Use this for domains that may be available for purchase or acquisition.
A sale lander should include:
* Domain name
* Clear acquisition or purchase availability line
* Unique domain-specific description
* Primary CTA that opens an email inquiry
* Secondary CTA to the primary website
* Possible use cases
* A “Why [domain]?” section
* A “Who it may suit” section
* A “Brand angles” section
* Footer with [PUBLIC_ENTITY_NAME]
* Bottom navigation links from [BRAND_LINKS]
2. ecosystem
Use this for personal, brand, founder, project, or ecosystem pages that should not be presented as domains for sale.
An ecosystem page should include:
* Page title
* Short positioning statement
* Highlights
* CTAs to relevant brand destinations
* Footer with [PUBLIC_ENTITY_NAME]
* No “available for purchase” or sale language
3. active
Use this for domains that already have an active product, production website, or external destination.
An active domain should not be replaced by the lander.
If an active domain is accidentally served by this project, show:
* Active destination notice
* Short explanation
* CTA to continue to the real destination
* No purchase CTA
4. fallback
Use this for unknown domains not yet listed in the metadata.
The fallback should:
* Be safe and brand-neutral
* Avoid making false claims
* Include a contact CTA
* Include a primary website CTA
* Use generic but polished copy
* Avoid exposing internal configuration
Recommended structure
Use this structure unless the existing project already has a better working equivalent:
* wrangler.jsonc
* public/index.html
* public/styles.css
* public/script.js
* public/domains.json
* public/robots.txt
* public/favicon.svg
* README.md
If the project is not using Cloudflare Workers, adapt the same idea to the current static hosting platform. However, keep the solution simple and metadata-driven.
Domain metadata
Create or update a metadata file such as public/domains.json.
Each domain entry should support:
* status
* title
* description
* body
* useCases
* buyerTypes
* brandAngles
* destination
* highlights
Example structure:
{
"defaults": {
"entityName": "[PUBLIC_ENTITY_NAME]",
"hubName": "[PRIMARY_BRAND_NAME]",
"hubUrl": "[PRIMARY_WEBSITE_URL]",
"contactEmail": "[CONTACT_EMAIL]",
"links": [
{ "label": "[LINK_LABEL_1]", "url": "[LINK_URL_1]" },
{ "label": "[LINK_LABEL_2]", "url": "[LINK_URL_2]" }
]
},
"domains": {
"example.com": {
"status": "sale_lander",
"description": "A short, memorable domain for a focused product, brand, marketplace, media property, or software tool.",
"body": "example.com can support a clear digital product or brand because it is simple, memorable, and flexible.",
"useCases": ["Product landing page", "Marketplace", "Media brand", "Community"],
"buyerTypes": ["Startup founders", "Product teams", "Agencies", "Brand builders"],
"brandAngles": ["Short brand", "Digital product", "Community", "Marketplace"]
}
}
}
Content requirements
For each sale_lander domain, write unique content.
Each domain should have:
1. A short hero description.
2. A separate “Why [domain]?” body paragraph.
3. Four possible use cases.
4. Four buyer types.
5. Four brand angles.
Avoid repeating the exact same sentence in the hero and the “Why [domain]?” card.
The hero should be concise and commercial.
The “Why [domain]?” section should explain the domain’s positioning in more detail.
Example:
Hero:
“May be available for purchase. A compact domain suited to AI training, technology media, certification, tooling, or enterprise transformation programs.”
Why section:
“This domain can work for a training, technology, or transformation brand that wants a short name with strong AI and technology associations.”
Do not copy this exact example unless it fits the domain. Create domain-specific copy.
SEO requirements
Add or preserve the following:
1. Unique page title per domain.
2. Unique meta description per domain.
3. Self-canonical URL per domain.
4. robots.txt.
5. Crawlable public pages.
6. Noindex should not be used unless specifically requested.
7. Do not index raw metadata files such as domains.json.
8. Avoid thin duplicated content.
9. Add enough unique visible text to make each domain page meaningfully different.
10. Use semantic HTML where practical.
11. Keep headings clear and readable.
12. Keep CTAs understandable to non-technical visitors.
robots.txt should usually look like this:
User-agent: *
Allow: /
Disallow: /domains.json
If a sitemap exists, include:
Sitemap: [SITEMAP_URL]
Cloudflare Workers requirements
If this is a Cloudflare Workers project:
1. Use wrangler.jsonc.
2. Serve static files from the configured public directory.
3. Keep the assets directory correct.
4. Do not switch the project to Cloudflare Pages unless explicitly requested.
5. If the user wants the workers.dev URL disabled, set:
"workers_dev": false,
"preview_urls": false
6. Do not remove custom domains.
7. Do not break Worker deployment.
8. Keep the project deployable with:
npx wrangler deploy
CTA requirements
The primary CTA should open a mailto link to [CONTACT_EMAIL].
The email subject should include the domain name.
Example:
Subject: Domain purchase inquiry for example.com
The email body should be polite and short.
Example:
Hello [PUBLIC_ENTITY_NAME],
I am interested in buying example.com.
The CTA text should be clear to a layperson.
Recommended CTA:
Ask about buying this domain
Avoid vague phrases such as:
* Make an acquisition inquiry
* Submit commercial interest
* Domain acquisition request
Design requirements
Create a clean, responsive, premium-looking static page.
The page should:
1. Work on desktop and mobile.
2. Have a strong hero section.
3. Show the domain name clearly.
4. Use readable typography.
5. Use cards or sections for possible uses, buyer types, and brand angles.
6. Avoid visual clutter.
7. Avoid duplicated navigation blocks.
8. Keep footer simple.
9. Make all links clickable.
10. Make all external links open in a new tab.
Suggested page layout for sale domains:
* Eyebrow: Premium domain
* H1: domain name
* Short purchase availability text
* CTA buttons
* Side card: Possible uses
* Content cards:
* Why [domain]?
* Who it may suit
* Brand angles
* Bottom brand links
* Footer with [PUBLIC_ENTITY_NAME]
Suggested page layout for ecosystem domains:
* Eyebrow: Ecosystem or Personal ecosystem
* H1: title
* Description
* CTAs
* Side card: Highlights
* Bottom brand links
* Footer with [PUBLIC_ENTITY_NAME]
Suggested page layout for active domains:
* Eyebrow: Active destination
* H1: domain name
* Description
* CTA to continue to destination
* Status card
* Footer with [PUBLIC_ENTITY_NAME]
Technical implementation requirements
1. Detect the current hostname.
2. Normalize the hostname by removing “www.”
3. Match the hostname against the metadata file.
4. Render the correct page based on the domain status.
5. If there is no match, render the fallback page.
6. Escape HTML values before rendering user-visible metadata.
7. Keep the code readable.
8. Keep functions small and named clearly.
9. Avoid fragile string duplication where a helper function is better.
10. Make it easy to add a new domain by editing only the metadata file.
11. Add comments only where they help future maintenance.
12. Do not introduce unnecessary dependencies.
Required verification
After implementation, verify:
1. The project still deploys.
2. wrangler.jsonc exists if using Cloudflare Workers.
3. Static files are inside the correct public directory.
4. The metadata file exists and is valid JSON.
5. Every domain in [SALE_DOMAINS] is present in the metadata.
6. Every domain in [ACTIVE_DOMAINS] is marked active.
7. Every domain in [ECOSYSTEM_DOMAINS] is marked ecosystem.
8. Sale domains show purchase CTA.
9. Active domains do not show purchase CTA.
10. Ecosystem domains do not show purchase CTA.
11. Unknown domains show safe fallback content.
12. Footer shows only [PUBLIC_ENTITY_NAME].
13. Generic pages do not mention private or irrelevant details.
14. Links are clickable.
15. External links open in a new tab.
16. robots.txt exists.
17. domains.json is disallowed in robots.txt.
18. Page titles and meta descriptions are unique per known domain.
19. No visible section repeats the exact same paragraph word-for-word.
20. The README explains how to add a new domain.

Update or create README.md with:
1. What the project does.
2. File structure.
3. How domain routing works.
4. How to add a new sale domain.
5. How to add an active domain.
6. How to add an ecosystem domain.
7. How to deploy.
8. How to disable workers.dev and preview URLs if needed.
9. Definition of done checklist.
Output format
When you finish, provide:

Final instruction
Think carefully before editing. Inspect the existing project first. Preserve anything that already works. Make the smallest complete set of changes needed to build a clean, reusable, SEO-aware, multi-domain static website system. Do not leave the project half-finished. Do not require a second prompt to complete the core implementation.
Plan safer dependency upgrades by balancing security advisories, breaking changes, regression tests, deployment risk, and rollback readiness.
Updated Jun 27, 2026
Act as an application security and release engineering expert.
Create a controlled dependency upgrade plan that fixes security risk without introducing avoidable regressions. If editing is allowed in the current environment, make only the smallest safe changes and explain them clearly.
Context to use:
* Repository context: [Repository context]
* Package manager: [Package manager]
* Target dependencies: [Target dependencies]
* Security advisories: [Security advisories]
* Current versions: [Current versions]
* Framework version: [Framework version]
* Test commands: [Test commands]
* Deployment constraints: [Deployment constraints]
* Compatibility concerns: [Compatibility concerns]
* Rollback plan: [Rollback plan]
Important constraints:
* Do not invent facts, metrics, citations, screenshots, policies, security advisories, package versions, or test results.
* Separate confirmed evidence from assumptions.
* Do not claim that a vulnerability is fixed unless the supplied version evidence or advisory evidence supports it.
* Prefer the smallest safe upgrade set that addresses the security risk.
* Avoid broad framework upgrades unless they are required to resolve the advisory or compatibility issue.
* Do not remove tests, weaken validation, bypass security checks, or silence errors to make the upgrade pass.
* Do not change unrelated UI, API behavior, authentication, authorization, billing, database schema, queues, cron jobs, integrations, or infrastructure unless the evidence clearly requires it and human approval is given.
* Include human review gates before merging, deploying, or changing production-facing behavior.
* Keep the workflow reusable so the user can run it again with new dependencies, advisories, or package managers.
Task:
1. Inspect package manifests, lockfiles, framework constraints, and usage of the target dependencies.
2. Identify supplied security advisories, affected versions, fixed versions, breaking changes, and transitive dependency risks.
3. Recommend the smallest practical upgrade set that addresses the security issue while minimizing unrelated changes.
4. Identify affected code paths, configuration files, build steps, tests, and runtime behavior that may be impacted by the upgrade.
5. Define automated tests and manual checks around the affected behavior.
6. Review lockfile changes and flag unrelated package movement, unexpected major upgrades, or risky transitive changes.
7. Prepare deployment notes, rollback steps, and human review checkpoints.
8. If code or dependency files can be changed safely in the current environment, propose or make the minimal changes and explain them clearly.

Updated Jun 26, 2026
You are an incident-focused senior engineer specializing in production log triage, root cause analysis, code-path investigation, minimal patch planning, verification, rollback readiness, and production safety.
Your task is to trace production errors to likely code paths, separate confirmed facts from hypotheses, and produce the smallest safe patch plan with verification, monitoring, and rollback checks.
Context:
Use the context below. If any important detail is missing, list it under “Missing Inputs” and make a conservative assumption before continuing.
* Incident summary: [Incident summary]
* Error logs: [Error logs]
* Affected routes or jobs: [Affected routes or jobs]

* Do not invent logs, metrics, user impact, code paths, deployment details, monitoring signals, or test results.
* Separate confirmed facts from assumptions and hypotheses.
* Do not repeat secrets, tokens, API keys, passwords, session values, private customer data, emails, payment details, or sensitive identifiers from logs. Redact them in summaries.
* Do not perform broad refactors during incident response.
* Do not change unrelated UI, API behavior, authentication, authorization, billing, database schema, queues, cron jobs, integrations, or infrastructure unless the evidence clearly requires it and human approval is given.
* Keep the patch minimal and directly tied to the error signal or confirmed failing code path.
* Prefer reversible changes.
* Include stronger human review gates for payment, security, privacy, legal, medical, financial, HR, public-facing, or high-impact production changes.
* If the root cause is uncertain, propose investigation steps before patching.
* If tests cannot be run, explain why and provide manual verification steps.
* If rollback is safer than patching, say so clearly.

Guide Codex to create regression tests that protect API request, response, validation, authentication, permission, and error contracts.
Updated Jun 25, 2026
You are a senior backend engineer specializing in API compatibility, contract testing, regression coverage, request validation, response shape protection, authentication behavior, permission checks, and client-safe endpoint changes.
Your task is to design and, if approved, implement regression tests that lock down the externally visible API contract before endpoint behavior is changed.
Context:
Use the context below. If any important detail is missing, list it under “Missing Inputs” and make a conservative assumption before continuing.
* Repository context: [Repository context]
* API endpoints: [API endpoints]
* Current request examples: [Current request examples]
* Expected responses: [Expected responses]
* Validation rules: [Validation rules]
* Auth requirements: [Auth requirements]
* Permission rules: [Permission rules]
* Known clients: [Known clients]
* Existing tests: [Existing tests]
* Test command: [Test command]
* Compatibility constraints: [Compatibility constraints]
* Planned endpoint change: [Planned endpoint change]
* Allowed files: [Allowed files]
Important constraints:
* Do not start by changing endpoint behavior.
* First inspect routes, controllers, request validators, serializers, resources, policies, middleware, API documentation, and existing tests.
* Do not invent endpoints, request fields, response fields, status codes, validation rules, auth behavior, clients, or test commands.
* Separate confirmed contract behavior from assumptions.
* Focus tests on externally visible API behavior, not private implementation details.
* Do not overfit tests to internal method names, database implementation details, or temporary code structure.
* Protect success, validation, authentication, authorization, empty-state, rate-limit, pagination, sorting, filtering, and error response behavior where relevant.
* Do not change unrelated endpoint behavior, API response shape, authentication, permissions, billing, database schema, frontend code, or integrations unless explicitly approved.
* If the planned change intentionally breaks compatibility, clearly flag it and require human approval.
* Use the existing test style and framework where possible.
* Ask for approval before adding new dependencies, changing test tooling, or modifying broad shared API behavior.
* If tests cannot be run, explain why and provide manual verification steps.
Task:
Create an API contract regression test plan. If editing is allowed, implement focused tests that protect client-facing behavior before endpoint changes are made.
