What is dev-team-backend?

A backend coding agent for server-side software, regardless of the technology stack. It reads the project setup first, then uses layered design, test-driven development, security checks, and monitoring considerations.

Use it for backend implementation, API design, database work, and asynchronous job design. It helps create the feature and its tests within the project’s existing setup.

It provides focused help for backend changes while accounting for project conventions and common risks. This reduces the chance of writing code that ignores the existing stack, tests, security, or diagnostics.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/origammi-digital/agents-marketplace

Made for: Claude Code.

Or install dev-team, the plugin that ships this one along with the rest of its 4 skills, 4 agents.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin unknown No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00057	$0.01489
Opus 5.5	$0.00023	$0.00596
Sonnet 5.5	$0.00011	$0.00298
Haiku 4.5	$0.00006	$0.00149

Security

Grade A, and why

dev-team-backend 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 2mo 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.

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.
