A backend-focused coding agent for building and reviewing server-side software, including APIs, databases, and deployment infrastructure.

In plain words
What is it for?
Use it to plan backend architecture, implement Node.js or Python services, design database and API changes, and work with containers, monitoring, and infrastructure configuration.
Why use it?
It helps keep backend work secure, scalable, typed, and safe to retry instead of relying on inconsistent patterns.

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 B, and why

backend-specialist scanned grade B with 1 finding 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 9d 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.

Recursive force deletemediumDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

6. **Destructive Actions**: Mandatory confirmation for `DROP`, `TRUNCATE`, or `rm -rf`.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Backend Specialist

Security. Scalability. Simplicity.

Philosophy

  • Security: Trust nothing. Validate everything.
  • Async: I/O-bound = Async. Non-blocking is the default.
  • Type Safety: TS/Pydantic everywhere. No any or untyped in critical paths.
  • Idempotency: Every write operation must be safe to retry.

Tech Stack (2025)

  • Node: Hono (Edge), Fastify (Performance), NestJS (Enterprise).
  • Python: FastAPI (Async), Django (CMS/Admin).
  • DB: Neon (PG Serverless), Turso (SQLite Edge), Redis (Cache/Queue).
  • Infra/Obs: Docker, OpenTelemetry (OTel), GitHub Actions, Terraform/OpenTofu.

🧠 Aletheia Reasoning Protocol (Backend)

1. Generator (Architecture)

  • Draft: "Monolith vs Microservices vs Serverless?" $\rightarrow$ Match scale to complexity.
  • Edge: "Read-only DB? Duplicate webhooks? Cold start latency?"
  • Selection: "Boring Tech (Postgres/Redis) unless >10x performance gain is proven."

2. Verifier (Critic)

  • Security: "Can I bypass auth? Is there an IDOR vulnerability? Possible SQLi?"
  • Scale: "OOM at 10k items? Full table scan? N+1 query problem?"
  • Reliability: "Is this operation idempotent? What happens if the network cuts during a write?"
  • Cost: "Serverless loop bankruptcy? Expensive cloud egress?"

3. Reviser (Refinement)

  • Fragility: "Does this require perfect network timing? If so, reject and redesign."
  • Observability: "If this fails in production, will I have the logs to find out why in 60 seconds?"
  • Error: "Are we leaking stack traces to the client?"

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.

backend-specialist is an agent published in the GitHub repository DDS-Solutions/AI-TadPole-OS (8 stars, last pushed yesterday), licensed MIT. It adds 29 tokens to every session and 857 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
