Apex

Engineering Lead

The lead who decides what to build, who builds it, and how deep to go.

Engineering lead for the Engineering Team. Scopes projects before any code is written, presenting S, M, and L depth options with time and token cost estimates so you control the investment. Dispatches and coordinates the 14 specialist agents for complex work, reviews cross-cutting concerns that individual specialists miss, and generates CTO-level status reports from git history and codebase state.

Everything Apex can do in your project

ApexPlanning

/apex-plan

Scopes a project or feature before any code is written. Reads the codebase and brief, challenges assumptions, and presents S, M, and L depth options with time and estimated token cost for each. You choose how deep to go before Apex dispatches any work to the team.

When starting any non-trivial project, feature, or…

ApexPlanning

/apex-review

Reviews a completed body of work across all layers: API design, data model, security, observability, tests, and documentation. Catches the integration gaps that happen when specialists work in their own lane: not errors any one specialist would make, but the things that only appear when you look at the whole.

After completing a significant feature, before a p…

ApexPlanning

/apex-status

Reads git history, open PRs, recent commits, and codebase state to produce a CTO-level status report. Shows what is done, what is in progress, what is blocked, and what the highest-risk items are at this point in the project.

At the start of a work session to orient before di…

ApexPlanning

/apex-takeover

Takes ownership of an inherited or unfamiliar codebase by orchestrating parallel reconnaissance across all 14 specialists simultaneously. Produces a full system map, risk assessment, quick wins list, and recommended roadmap. This is the starting point when joining a project mid-stream.

When inheriting a codebase from another team, when…

ApexPlanning

/apex-recon

Engineering lead reconnaissance: reads the codebase structure, git history, open work, and dependency graph to produce a focused inventory before planning begins. Faster and lighter than a full takeover, designed for orientation rather than comprehensive handoff documentation.

At the start of a session on a project you have no…

/tonone-onboard

Guided onboarding tour of tonone's 23 agents, key skills, and worktree sessions. Two paths: expert (~90 sec) and newcomer (~8 min). Cross-agent — not tied to any single specialist.

When asked 'how do I use tonone', 'what can tonone…
