fe-framework-coding-standard

A set of frontend coding guidelines for projects using React Native, React, Flutter, Vue, Angular, or Next.js. It reads the project's approved software requirements before guiding implementation or review.

In plain words
What is it for?
Use it when building, refactoring, or reviewing frontend screens and components. It covers framework-specific code, test selectors, loading/error/empty states, design requirements, and related tests.
Why use it?
It helps keep UI code consistent with the project's chosen framework and existing structure. It also reduces missed interface details, states, tests, and required design assets.

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

fe-framework-coding-standard 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 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.

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.

FE Framework Coding Standard

When to use

You are FE Dev implementing or reviewing UI code after the stack is declared in the signed-off SRS. This skill standardizes how to write framework-specific code without turning every task into a framework migration.

Inputs and outputs

  • Inputs: task assignment, docs/SRS.md header Frontend-Framework:, SRS §3.4.2 UI Introspection Profile, SRS §3.4.5 Source Layout, SRS §3.4.6 Environment Configuration, SRS user story / FR / NFR IDs, design handoff, Reference Render, Visual Composition Contract, Asset Export Manifest, Design Element Manifest, visual spec assertions, instrumentation contract, architecture decisions, current frontend source tree, installed framework versions and libraries.
  • Outputs: framework-native UI code that follows the project's existing architecture, names stable test selectors, implements every required Figma field/item/copy/action, reproduces the contracted composition, uses every required exported asset, handles loading / error / empty states, satisfies design tokens where available, and includes the appropriate unit / component / E2E updates.

Framework selection

  1. Read docs/SRS.md before inspecting package files. The header Frontend-Framework: is authoritative.
  2. If the header is one supported value, select that framework reference.
  3. If the header is multiple, select the framework from the row that owns the task:
    • use SRS §3.4.2 for a surface-driven task;
    • use SRS §3.4.5 for a path/app-driven task;
    • if the task maps to more than one framework or no row matches, halt with NEEDS_CONTEXT and cite the candidate SRS rows.
  4. If the header is N/A, do not perform FE framework implementation; report that no frontend framework applies.
  5. If the header is missing, TBD, unsupported, or inconsistent with §3.4.2 / §3.4.5, halt and return the work to BA:
    • greenfield/authored SRS: BA Phase 1.X step 10c must ask the user to choose;
    • brownfield/extracted SRS: BA Mode E must detect from source evidence and write the SRS field.
  6. After selecting the reference, inspect package files/source only as a consistency check. If code evidence contradicts the SRS-selected framework, halt and raise an open issue; do not silently switch references.

7 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.
