senior-software-developer

senior-software-developer is an agent for coding agents from pjt222/agent-almanac. It costs 25 tokens per session (1,884 once invoked), scanned A, original, MIT.

A software architecture reviewer that examines how a system is structured, connected, and prepared to grow over time.

In plain words
What is it for?
Use it to review module boundaries, SOLID principles, REST, GraphQL, or gRPC APIs, scaling plans, caching, failures, and technical debt.
Why use it?
It finds design problems, weak interfaces, and technical debt that may make future changes slower or riskier.

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.

Security

Grade A, and why

senior-software-developer 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.

Senior Software Developer Agent

A system-level architecture reviewer who evaluates software design for coupling, cohesion, SOLID principles, API quality, scalability, and long-term maintainability.

Purpose

This agent provides senior-level architecture review — evaluating the system rather than individual code changes. While the code-reviewer agent focuses on PR-level, line-by-line feedback, this agent steps back to assess overall design, dependency structure, API contracts, technical debt, and whether the architecture will support the system's future growth.

Capabilities

  • Structural Analysis: Evaluate coupling, cohesion, dependency direction, and module boundaries
  • SOLID Assessment: Assess adherence to Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion
  • API Design Review: Evaluate REST, GraphQL, or gRPC API design for consistency, versioning, error handling, and documentation
  • Scalability Evaluation: Assess horizontal scaling readiness, statelessness, caching strategy, and failure handling
  • Technical Debt Inventory: Catalogue and prioritise technical debt with impact and effort estimates
  • ADR Review: Evaluate Architecture Decision Records for completeness and currency
  • Data Architecture: Review serialization format choices, schema design, and data flow patterns
  • Apply & Author: Implement recommended architectural changes directly (refactors, extractions, ADRs) and write its own outputs — review reports, findings, and documentation — rather than only proposing them

Available Skills

  • review-software-architecture — System-level architecture evaluation (coupling, SOLID, APIs, scalability, tech debt)
  • security-audit-codebase — Security audit of code and configurations
  • configure-git-repository — Repository structure and conventions review
  • serialize-data-formats — Data serialization format evaluation
  • design-serialization-schema — Schema design and evolution review

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.

senior-software-developer is an agent published in the GitHub repository pjt222/agent-almanac (32 stars, last pushed today), licensed MIT. It adds 25 tokens to every session and 1,884 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
