shift-left-testing

shift-left-testing is a skill for Claude Code, Codex from upex-galaxy/agentic-qa-boilerplate. It costs 303 tokens per session (12,038 once invoked), scanned A, original, MIT.

A pre-sprint QA workflow for reviewing a group of backlog stories before development starts. It refines acceptance criteria, which are the conditions a story must meet, and identifies unclear or missing requirements.

In plain words
What is it for?
Use it to clarify stories, expose ambiguities, draft a test-plan outline, and give product and development teams actionable requirements before sprint work begins.
Why use it?
Finding gaps before a story enters a sprint is cheaper than discovering them after implementation. The workflow connects the refined criteria to the project's business maps, API contracts, and existing test planning.

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

shift-left-testing scanned grade A with 1 finding 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 509 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Inputs

Read in order; stop earlier when the batch is small enough that later inputs add no signal.

  1. .context/business/business-feature-map.md + .context/business/business-data-map.md + .context/business/business-api-map.md — domain vocabulary, entity model, CRUD matrix, auth model + endpoint contracts. Anchors refined ACs in real entities, flows, and API behavior. (All three are hard-required by the Readiness Preflight Gate + Phase 0.3.)
  2. .context/master-test-plan.md — regression Epic + in-scope modules. Tells the refinement whether the Story falls inside an already-prioritized area.
  3. The Story's Acceptance Criteria + **Source spec:** reference on Jira. Detailed read via bun run jira:sync-issues get <STORY_KEY> --include-comments, then read the synced acceptance-criteria.md (+ description). NEVER acli view for custom fields. Canonical input — every refined AC must trace back here.
  4. .context/PBI/epics/EPIC-<KEY>-<slug>/stories/STORY-<KEY>-<slug>/ if a PBI folder already exists for this Story (created by a prior /sprint-testing cycle). Carries earlier session notes worth honoring.
  5. .agents/jira-workflows.json — Story workflow + valid transitions (backlog -> shift_left_qa -> estimation). Source of {{jira.transition.story.*}} slugs used in Phase 3. ALSO the resolver for the [QA] Shift-Left Review tracking subtask: read it to confirm a subtask work type exists (+ its transitions) before Phase 1 creates any subtask; if the catalog has no subtask work type, the subtask steps are skipped with a warning — never blocked on.
  6. .agents/jira-required.yaml — canonical slug catalog. Source of {{jira.acceptance_test_plan}} and other Jira field slugs touched in handoff.

Forbidden invocations

NEVER invoke /sdd-* skills from this workflow. SDD is an optional user-installed ceremony; this skill ships self-contained and does not chain SDD under any condition. If you need to refactor KATA, fixtures, cli/, scripts/, or api/schemas/ pipeline, exit this skill first and invoke /framework-development.

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.
