What is bdd-generate?

A workflow for creating pytest-bdd test scaffolding from existing acceptance criteria or Given/When/Then scenarios. BDD, or behaviour-driven development, describes software tests in terms of expected user behaviour.

Use it to generate feature files, scaffold BDD tests, or connect existing scenarios to pytest-bdd. It requires acceptance criteria or scenarios first.

It removes the repetitive setup needed to turn agreed behaviour scenarios into runnable pytest-bdd test files.

bdd-generate — Skill for Claude Code by JoshuaOliphant

Install

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.

Any agent

npx skills add JoshuaOliphant/claude-plugins --skill bdd-generate

Clone the repo

git clone --depth 1 https://github.com/JoshuaOliphant/claude-plugins

Made for: Claude Code.

Or install autonomous-sdlc, the plugin that ships this one along with the rest of its 5 skills, 4 commands, 2 agents, 5 hooks.

Per session 93 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 1,658 The whole file, excluding the scripts and references it only reads on demand.

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	$0.00093	$0.01658
Opus 5	$0.00046	$0.00829
Sonnet 5	$0.00019	$0.00332
Haiku 4.5	$0.00009	$0.00166

Measured 7d ago against content hash 3c196da42807, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-07, from the pricing page.

Security

Grade A, and why

bdd-generate 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 7d 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 ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

bdd-generate is a skill published in the GitHub repository JoshuaOliphant/claude-plugins (6 stars, last pushed yesterday), with no licence file. It adds 93 tokens to every session and 1,658 once invoked, about $0.0005 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 2026-08-31.
