research-first-development

research-first-development is a skill for Claude Code, Codex from fabioc-aloha/Alex_Skill_Mall. It costs 18 tokens per session (4,207 once invoked), scanned A, original, MIT.

A software-development approach that researches and explains an unfamiliar subject before planning and writing code.

In plain words
What is it for?
Use it when starting a project, entering a new implementation phase, onboarding to a domain, or preparing for complex multi-part development.
Why use it?
It gives the coding agent the background it needs when a project, domain, or subsystem is unfamiliar.

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

research-first-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 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.

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.

Research-First Development

Build knowledge bases that build software — research before code, teach before execute

Methodology for AI-assisted development where investment in research, skill creation, and knowledge encoding precedes implementation. Discovered through the Dead Letter heir's masterclass on cognitive architecture utilization (February 2026).


When to Use

  • Starting any new project with the AI assistant
  • Entering a new implementation phase of an existing project
  • Onboarding the AI assistant to an unfamiliar domain
  • When AI output quality is inconsistent (symptom: insufficient context)
  • Before any complex multi-subsystem implementation

Core Insight

Traditional software development: Requirements → Design → Code → Test

AI-assisted development with cognitive architecture: Research → Teach → Plan → Execute

The quality of AI output is directly proportional to the quality of knowledge in its context.

Instead of the human writing code with AI assistance, the human orchestrates intent while AI handles execution. But AI can only execute what it understands. Therefore: invest in teaching before asking for output.


The Research-First Paradigm

Phase 0: Research Sprint (Before Any Code)

Step Activity Output
1 Competitive landscape analysis Understanding of prior art
2 Technical feasibility research Deep research documents (3-5 minimum)
3 Architecture decision records ADRs documenting key choices
4 Core domain research Comprehensive domain knowledge
5 Branding/identity decisions Project character and voice

Each research document should:

  • Explore one domain exhaustively
  • Cite sources: academic papers, industry best practices, competitive analysis
  • Be structured with clear sections, code examples, decision rationales
  • Live in a /docs/ or /research/ directory

Phase 1: Knowledge Encoding (Research → Skills)

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.
