What it does
Quality Engineering Business Analysis is an agent skill from HoangNguyen0403/agent-skills-standard. Investigate requirements via atomic AC decomposition, actor/permission matrices, and truth-table edge cases; enforce User Story standards (scope fences, platform tags, toggles). Use when writing/reviewing Stories or AC with multi-condition logic, feature toggles, or market variants (VN/MY/SG).
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `evals/evals.json`, `references/analysis_patterns.md` and `references/logic_truth_tables.md`).
It sits in Product & Project Management, covering User stories. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.
When your agent uses it
- Writing/reviewing Stories
- AC with multi-condition logic
- Feature toggles
- Market variants (VN/MY/SG)
Example prompts
- “/quality-engineering-business-analysis”
Workflow steps
7 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit b529c2d. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Quality Engineering Business Analysis loads about 1k tokens when it runs, and up to ~2.7k if it reads all its reference files. Until then it costs about 83 tokens; SKILL.md has 465 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- quality-engineering-business-analysis
- description
- Investigate requirements via atomic AC decomposition, actor/permission matrices, and truth-table edge cases; enforce User Story standards (scope fences, platform tags, toggles). Use when writing/reviewing Stories or AC with multi-condition logic, feature toggles, or market variants (VN/MY/SG).
Business Analysis Standards (Deep Analysis + Story Authoring)
Priority: P0 (CRITICAL)
1. Deep Investigation Protocol
- Atomic AC Decomposition: Split Acceptance Criteria (AC) into 1-Condition logic units (e.g., "User can X and Y" -> "User can X", "User can Y").
- Variable Identification: Extract all Feature Toggles, Market Rules (VN/MY/SG), and User Roles.
- Platform Parity: Verify if logic applies to both Web and Mobile; Flag divergent behavior early.
- Truth Table Verification: Map complex multi-condition logic to Logic Truth Table.
2. Dynamic Actor & Permission Mapping
- Identify all Actors (e.g.,
Customer,Sales Rep,Admin). - Use Actor/Permission Matrix to map specific constraints per Actor.
- Permissions Patterns
3. Edge Case & Boundary Analysis
- State Validation: Verify behavior across all entity (e.g.,
Active,Suspended) and network states. - Boundary Detection: Analyze currency, date, and count limits.
- Negative Testing: Identify flows for Unauthorized Access, Invalid Input, and Null-safety.
4. Anti-Patterns (Analysis)
- No Surface Reading: investigate implications, don't restate.
- No Assumption: Flag undefined states (e.g., Offline) as P0 blockers.
- No Loose Mapping: Ensure AC aligns 100% with Technical Impact notes.
5. User Story Authoring Standards
- Story Structure: Every story must use
As a [Actor], I want [Goal], so that [Value]. - AC Format: Each AC must one
Given / When / Thenblock — one condition per block. - Platform Tag: Prefix each AC with
[WEB],[MOBILE], or[BOTH]— never mix platforms in one AC block. - Toggle Contract: Each feature flag AC must name flag and state:
Toggle: <FlagName> = ON/OFF. - Market Isolation: Any market-specific AC must prefixed
[Market: VN],[Market: MY], etc. - Scope Fence: Include explicit
## In Scope,## Out of Scope, and## Deferredsections. Deferred items must link to Jira ticket — never write "to discuss". - Translation AC: Language/locale behavior separate AC, not inline note.
See User Story Template for full authoring template.
Show full SKILL.md (181 more words)Show less
6. Anti-Patterns (Story Authoring)
- No mixed-platform AC:
[MOBILE ONLY]buried inline hides parity gaps — use platform tags. - No "to discuss": Replace with linked Jira ticket in
## Deferred. - No implicit toggle states: Always declare both ON and OFF behavior per AC.
- No bundled AC: "User sees X and Y and Z" → split into three separate AC blocks.
7. Validation Checklist
Run after authoring or reviewing any User Story before marking it ready for development:
- Every AC
[WEB],[MOBILE], or[BOTH]platform tag - Every toggle AC declares both
= ONand= OFFstates explicitly - No AC block contains more than one
Andcondition (split if it ) - No "to discuss" text anywhere — replaced by Jira link in
## Deferred - Story
## In Scope,## Out of Scope, and## Deferredsections - Story uses
As a / I want / So thatheader - Market-specific ACs prefixed
[Market: VN],[Market: MY], etc. - Translation / locale behavior its own AC or deferred with Jira link
