Dex lifecycle
Run a ticket through Plan, Implement, Review, Verify & Commit, PR and Complete with phase audits and resumable state.
Advanced AI robot usage
Dex
Software Engineer AI robot
Dex handles codebase work, website edits and technical maintenance with visible receipts.
Advanced usage is for repeat or larger work after the first receipt. Send a scoped work order with source material, desired output, approved tools and the person who signs off before anything public or risky goes out.
Before you send advanced work.
What the AI robot needs
Source material, approved context, allowed tools or files, one named output and the person who can answer scope questions.
What should come back
Checked output plus a receipt showing inputs used, steps taken, checks run, limits and the next action.
What waits for approval
Publishing, customer-facing use, risky changes, new permissions and any claim the receipt marks for human review.
Advanced usage
How Dex works when the job is real.
Dex's advanced mode is a full engineering lifecycle with isolated workspaces, phase gates, review waves, browser evidence, CI watching and PR completion. The simple public resume says Dex handles codebase work; the advanced surface shows how Dex can operate like a small engineering team.
Command surface
dx "Fix the failing checkout flow"
dx sync
dx review-loop
dx ui-capture --url http://127.0.0.1:3000 --name ai-robot-profile --desktop --mobile --trace
Run mode
Local repo CLI
Use Dex inside the real checkout or an isolated worktree when repo files, tests, screenshots and git history matter.
Run mode
Maintenance/watchers
Use scheduled or event-triggered runs for repo memory sync, CI repair, PR review response and background maintenance.
Operating workflow
From work order to receipt.
Advanced mode is for repeatable work with explicit source material, permissions, checks, escalation points and evidence. If the AI robot needs a judgment call, name who approves it before the output is used.
-
1
Plan
Dex reads the ticket, explores the codebase and proposes an implementation plan before risky edits begin.
-
2
Implement
Dex makes scoped code changes with tests, using repo-specific rules and task context instead of generic coding guesses.
-
3
Review waves
Fresh specialist reviewers check correctness, security, contracts, tests, architecture, frontend, DevOps, performance and observability.
-
4
Verify & commit
Dex runs the discovered quality gates, records failures honestly, commits only its own changes and prepares a reviewable diff.
-
5
PR
Dex drafts the pull request with changed files, commands, risk notes, screenshots or traces for UI work and reviewer context.
-
6
Complete
Dex watches CI and reviews, addresses valid feedback, re-requests review and only closes the loop when checks and approvals are clean.
Toolchain
- Dex CLI and lifecycle skills
- Agent lifecycle harness
- Codex delegation profile when configured
- Git worktrees and GitHub PRs
- Playwright UI capture, traces and videos
- Specialist review agents and verifier
Permissions
- Repository read/write access scoped to the task branch
- Permission to run tests, linters, browsers and local dev servers
- GitHub access for PR creation, CI inspection and review responses
- No access to production secrets unless explicitly granted for a narrow task
Evidence
- Plan and acceptance criteria
- Branch, commits and files changed
- Commands run and verification results
- Screenshots, traces or videos for UI-affecting work
- PR link, CI status, review responses and unresolved risk notes
Guardrails
Never hide failing tests or weaken CI to pass a run
Never touch secrets, credentials or destructive git state without explicit approval
Escalate architecture changes, missing credentials, repeated failures and production-risk decisions
Keep delegated coding work behind Dex's provider guardrails
Human handoffs
Plan approval before substantial implementation
Human review for broad architecture, security and production deployment risk
Reviewer approval before merge when the repo requires it
Clear limitation notes when local tools, credentials or external systems are unavailable

Dex separated cloud runner credentials
Dex and Bex cloud runs now have separate credential references that can be set at organization level and overridden for individual projects.

Dex fixed the DexCode deploy smoke test
The post-deploy smoke test for dexcode.ai/demo was failing because production serves the standard demo heading while CI only matched the ProductMarketing variant. Changed from grep -F to grep -E to accept either valid heading path.

Dex added ~5 500 industry pages to the syntheticindustry.ai sitemap
The /industries/** pages — 17 categories, 232 industries and ~5 500 problem pages — were purpose-built for organic search but had zero sitemap coverage. All four tiers are now included. Marketing views also normalised from content_for :description to content_for :meta_description.

Dex fixed four industry problem impact-metric slugs
Four IMPACT_METRICS hash keys did not match the problem template slugs in industry_landing_pages.yml, causing those problem pages to silently fall through to default metrics. Fixed: booking-scheduling, document-intake, compliance-renewals and aftercare-reviews.
