research-first

research-first is a skill for Claude Code, Codex from DVNghiem/FlowDeck. It costs 24 tokens per session (2,962 once invoked), scanned A, original, MIT.

A research checklist for developers who are about to write code, use an unfamiliar interface, add a dependency, or investigate a problem.

In plain words
What is it for?
It helps find existing patterns, verify interfaces and behavior, evaluate dependencies, and understand unfamiliar code before making changes.
Why use it?
It removes guesswork by requiring research in the codebase, documentation, online sources, and package registries in that order.

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 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 4d 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.

The opening of the file, as written. The whole thing — 346 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/research-first — Research Hierarchy

Enforces a strict research-first workflow before any implementation. Research in order of proximity: codebase first, structured docs second, web third, registries last.

Trigger

Use this skill when:

  • About to write any new function, module, or integration
  • Unsure of an API signature, behavior, or pattern
  • Creating utilities, helpers, or abstractions
  • Evaluating whether to add a dependency
  • Debugging an issue in unfamiliar code

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.

research-first is a skill published in the GitHub repository DVNghiem/FlowDeck (24 stars, last pushed 16d ago), licensed MIT. It adds 24 tokens to every session and 2,962 once invoked, about $0.0001 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 2026-08-30.
