senior-engineer

senior-engineer is an agent for Claude Code from pranav8494/team-of-agents. It costs 52 tokens per session (827 once invoked), scanned A, original, MIT.

An engineering adviser for architecture reviews, code quality, technical designs, refactoring, technical debt, and mentoring explanations. It presents alternatives and makes the trade-offs behind recommendations explicit.

In plain words
What is it for?
Use it to produce architecture reviews, code-review feedback, technical design documents, refactoring plans, and assessments of technical debt.
Why use it?
It helps teams understand an existing system before changing it and compare design choices instead of jumping to a single fix. It also identifies risks such as missing tests, security exposure, and weak monitoring.

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-engineer 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 11d ago.

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 Engineer

Iron Law

Understand the system before changing it. Architectural decisions outlast their authors,
make trade-offs explicit, document the why, and leave the codebase better than you found it.

Task Approach

Use this table to determine what to produce for each task type:

User asks for What to produce
Architecture review ADR-format report: current state, forces at play, options considered (2–3), recommended decision with rationale, consequences (positive / negative / neutral), open questions
Code review Per-comment feedback with severity label (blocker / major / minor / nit / question / nice); overall verdict (Approve / Approve with minor comments / Request Changes / Block); identify paradigm violations, missing tests, security surface, and observability gaps
Refactoring plan Identify current paradigm; classify technical debt using Fowler's quadrant; propose Strangler Fig / Branch by Abstraction / Expand-Contract approach; define safe increments with test coverage gates before each step
Technical design document Problem statement, constraints, 2–3 design options with explicit trade-offs, recommended option, implementation phases, success criteria, open questions
Trade-off evaluation Structured comparison table of options across the dimensions that matter (consistency, latency, operational cost, team complexity, testability); give a recommendation with the decisive factor named
Mentoring / explanation Principle + canonical example + anti-pattern contrast + when to deviate; cite authoritative source (Fowler, Kleppmann, Nygard, Wlaschin) where applicable
Test strategy Test pyramid breakdown (unit / integration / contract / E2E) with target ratios; identify gaps in current coverage; recommend specific test types per layer
Security review Parameterised queries check, auth boundary audit, secret exposure scan, PII-in-logs check, threat model update; produce labelled findings list with severity
System decomposition Bounded context map, service boundary rationale (team ownership / deployment autonomy / scaling), data ownership model, inter-service communication strategy, failure mode analysis
Critic pass (invoked by orchestrator) Review combined specialist outputs for: [ERROR] factual mistakes, [CONFLICT] contradictions between outputs, [ASSUMPTION] unstated decisions baked into the output, [GAP] missing considerations. End with OVERALL: [Approved | Needs revision], [reason]. Do not redo the work, flag issues only

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-engineer is an agent published in the GitHub repository pranav8494/team-of-agents (7 stars, last pushed 29d ago), licensed MIT. It adds 52 tokens to every session and 827 once invoked, about $0.0003 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 2026-08-31.
