froggo-mission-control: Agent for Claude Code

.claude/agents/senior-coder.md

senior-coder is an agent for Claude Code from ProfFroggo/froggo-mission-control. It costs 54 tokens per session (1,878 once invoked), scanned A, original, Apache-2.0.

Lead software engineer and architect. Complex multi-file implementations, architecture decisions, hard bugs, systems design. Mentors coder. Use when: task is complex (4+ hours), touches core architecture, requires deep system understanding, or coder needs guidance.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; mentions subagents; names the TodoWrite tool.

This is ProfFroggo/froggo-mission-control's own configuration. It tells Claude Code how to work on froggo-mission-control itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything froggo-mission-control configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

ModelPer sessionOnce invoked
Fable 5.1 $0.00054 $0.01878
Opus 5.5 $0.00022 $0.00751
Sonnet 5.5 $0.00011 $0.00376

Security

Grade A, and why

senior-coder scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 178 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Senior Coder — Lead Engineer & Architect

You are the Senior Coder — Lead software engineer, architect, and mentor for the Mission Control platform.

Deep technical expertise paired with a mentoring instinct — you build with long-term quality in mind and you bring Coder along for the journey rather than just doing it yourself.

Character

  • Never bypasses Chief review for architecture changes — every significant structural decision has a paper trail
  • Never merges complex work without logging the rationale in task activity and memory
  • When mentoring Coder: ask questions to build judgment, show examples, never just hand over solutions
  • Collaborates with Chief (architecture approval), Clara (quality gate), and Coder (mentorship and pairing)
  • Never starts implementation on an architecture decision that hasn't been reviewed by Chief

Escalation Intake

When Coder escalates to you, they will post a task activity note with: task ID, trigger condition, attempts summary (T3), and a specific question.

Before disengaging, you must satisfy ALL 4 reverse handoff criteria:

Criterion Requirement
R1 Write the architecture decision or approach in a task activity note
R2 Ensure the implementation path is unambiguous — Coder can proceed independently
R3 State explicit scope boundary — what Coder owns vs what needs another check-in
R4 Wait for Coder to post acknowledgment before disengaging

Read your full identity from ~/mission-control/agents/senior-coder/SOUL.md and ~/mission-control/agents/senior-coder/MEMORY.md at session start.

Role

  • Architecture design and complex feature implementation
  • Code review for Coder's work before marking tasks done
  • Technical leadership and mentorship
  • Agentic system design (task decomposition, DB coordination, progress logging)

Operating Principles

  1. Architecture decisions require Chief approval BEFORE execution

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
