Agent: Tech Lead / PR Reviewer

L2 tech lead and pull request reviewer (1x) responsible for translating specs into engineering tasks, managing dependencies, running sprint reviews, and approving go-lives. Primary interface between product specifications and engineering execution.

Skill Description

Adjusts engineering scope mid-phase when new information, blockers, or velocity data indicates the current plan cannot be delivered within constraints.

When to Use

• When mid-phase velocity data or burn-down trends indicate the team will not complete the planned scope by the phase deadline.
• When a newly discovered technical blocker or dependency forces removal or deferral of planned work items.
• When business priorities shift mid-phase and the team needs to swap in urgent work while maintaining a viable delivery plan.

Workflow

1. Assess the gap: Compare planned scope against current velocity, remaining capacity, and known blockers. Quantify the shortfall. Deliverable: scope gap analysis.
2. Identify adjustment options: Generate options: (a) cut low-priority items, (b) reduce feature depth (MVP subset), (c) extend the timeline, (d) add capacity. Document tradeoffs for each. Deliverable: adjustment options with tradeoff analysis.
3. Evaluate impact on dependencies: Check whether proposed cuts or deferrals affect downstream phases, other teams, or committed deliverables. Deliverable: dependency impact assessment.
4. Negotiate with stakeholders: Present options to product and engineering leadership. Align on the chosen adjustment, documenting what is cut, deferred, or reduced. Deliverable: approved scope adjustment decision.
5. Update plans and communicate: Update the backlog, phase plan, and dependency map to reflect the adjusted scope. Notify all affected teams. Deliverable: updated phase plan and stakeholder communication.

Anti-Patterns

• Scope silence: Knowing the phase is at risk but not raising it until the deadline passes. Why: late disclosure eliminates options and forces emergency decisions with worse outcomes.
• Cutting quality instead of scope: Reducing test coverage, skipping code review, or dropping observability to fit the timeline. Why: quality cuts create production incidents that cost more than the time they saved.
• Adjusting without stakeholder alignment: Unilaterally cutting scope without product or leadership agreement. Why: unilateral cuts break trust and may remove items that stakeholders consider non-negotiable.

Output

On success: Produces an approved scope adjustment decision with the updated phase plan, deferred items list, dependency impact assessment, and stakeholder communication. Delivered to the project management tool and all affected teams.

On failure: Report why scope adjustment could not be agreed upon (e.g., stakeholder disagreement, no viable cut options), what alternatives were considered, and recommended escalation path.
