What is dev-swarm-code-development?

A backlog implementation workflow for turning product requirements into working code and project documentation. It reads requirements, technical rules, sprint items, and existing feature records before making changes.

Use it to implement features, changes, bug fixes, and improvements from a sprint backlog. It can also update the project's feature knowledge base.

It gives feature work a consistent path from an approved task to an implemented and documented result. This reduces the risk of ignoring acceptance criteria or duplicating existing work.

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	$0.00044	$0.03226
Opus 5.5	$0.00018	$0.01290
Sonnet 5.5	$0.00009	$0.00645

Security

Grade A, and why

dev-swarm-code-development 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 16d 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.

AI Builder - Code Development

This skill implements backlogs through a structured feature-driven approach. As a Software Engineer expert, you'll read backlog requirements, reference existing features, design implementation approach, write code, and create comprehensive documentation for the features knowledge base.

When to Use This Skill

User asks to implement a backlog
User requests to complete a feature, change, bug fix, or improvement
User says "develop backlog X"
User wants to implement work from sprint
User asks to code a specific backlog item

Prerequisites

This skill requires:

04-prd/ - Product Requirements Document (business requirements and acceptance criteria)
07-tech-specs/ - Engineering standards and constraints
10-sprints/ folder with active sprint and backlogs
features/ folder with features-index.md (existing features knowledge base)
Understanding of the backlog type: FEATURE, CHANGE, BUG, or IMPROVE

Feature-Driven Development Workflow

CRITICAL: This skill follows a strict feature-driven approach where feature-name is the index for the entire project:

For Each Backlog:

Read backlog from 10-sprints/SPRINT-XX-descriptive-name/[BACKLOG_TYPE]-XX-[feature-name]-<sub-feature>.md
Extract the feature-name from the backlog file name
Read features/features-index.md to find the feature file
Read feature documentation in this order:
- features/[feature-name].md - Feature definition (WHAT/WHY/SCOPE)
- features/flows/[feature-name].md - User flows and process flows (if exists)
- features/contracts/[feature-name].md - API/data contracts (if exists)
- features/impl/[feature-name].md - Implementation notes (if exists)
Locate source code at {SRC}/ using features/impl/[feature-name].md
Implement the code following 07-tech-specs/
Update backlog with development notes

This approach ensures AI developers can work on large projects without reading all code at once.
