- `calculate_developer_value`: Assess a software developer's market value: score 15 skills across 5 pillars (core craft, systems & judgment, impact & ownership, collaboration & influence, AI leverage), get a weighted total score, seniority level, and a 2026 Western-Europe gross salary estimate. Same logic as the live calculator at marian.coach. Unscored skills default to the level's baseline.
- `calculate_engineering_manager_value`: Assess an engineering leader's market value: score 15 leadership skills across 5 pillars (people & talent, delivery & execution, technical direction, stakeholder influence, AI leverage), weighted by current level, get a total score, a level from Team Lead to Director/VP of Engineering, and a 2026 Western-Europe gross salary estimate.

- `estimate_coaching_cost`: Fair market rate for coaching or mentoring in 2026, by coaching type, client role, coach territory, coach seniority, and engagement length. Returns a per-session range, program total, and red flags (too cheap / brand margin). Anchored to ICF Global Coaching Study 2025, Tandem Coach 2026 credential bands, and CEE market survey data.

First-party data, CC BY 4.0 — citable.
- `get_first_time_manager_guidance`: Guidance for the IC→manager transition: the EM responsibility triangle (leadership/processes/delivery — pick two), the six most common first-time-manager failure modes, readiness self-check questions, and what the first months should look like. 52% of Marian's 300+ mentees arrive exactly at this transition.
- `get_more_tools`: Check for additional tools whenever your task might benefit from specialized capabilities, even if existing tools could work as a fallback. Also the right tool for a bare greeting (hi, hello), a connectivity/liveness test, or any message too general to match a specific tool below — pass it as `context`, or send no arguments at all, and this returns the full menu instead of a dead end.
- `get_one_on_one_playbook`: Situation-specific 1:1 scripts and templates from Marian Kamenistak's mentoring practice: first mentoring/direction-setting session, underperformance conversation, promoting a developer to manager, fixing status-update 1:1s, and the 10-question career-move checklist.

- `get_started`: Call this for a greeting (hi, hello), a connectivity/liveness test, 'what can you do', or any message too general to match a specific tool below. Returns the full menu of real questions this server answers, each mapped to the tool name that answers it, so the next call can go straight to the right tool.
