sdd-tdd

sdd-tdd is a skill for Claude Code, Codex from vladm3105/aidoc-flow-framework. It costs 35 tokens per session (306 once invoked), scanned A, original, MIT.

A test-design skill for writing TDD cases, where TDD means defining tests before implementation. Each case names what it checks, sets up its inputs, states the expected observable result, and gives verification criteria.

In plain words
What is it for?
Use it to define test cases for every specified interface and to prepare the tests that a later evaluation step will run.
Why use it?
It prevents vague test notes and untested interfaces. It makes failures point to a broken software contract rather than to an unclear test.

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

sdd-tdd 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 19d 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 it actually says

SDD TDD Author

Framework skill — routes to framework/layers/07_TDD/TDD-TEMPLATE.yaml and TDD_WORKFLOW_STANDARD.md (entry gate GATE-06). Paths below use <skills-root> = this framework/skills/ directory. Upstream: sdd-spec interfaces are the test surface.

1. Assert the contract, arrange the fixtures

Each test case names its target (component + interface), arranges fixtures explicitly, asserts observable behavior, and states verification criteria. A case without an assertion is a note, not a test — promote it or delete it.

2. Cover the SPEC, exactly

Every SPEC interface gets cases; every case traces to one interface. Like BDD: uncovered surface is risk, double-covered surface is a future contradiction. New sections stay inside existing mappings (test_strategy) so the deterministic layer fixtures keep passing.

3. Seal and hand off

Gate: GATE-06. Cases here are what sdd-eval executes — write them so that a FAIL verdict names the broken contract, not the test. Next: sdd-iplan (then code, then sdd-eval).

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.
