PetSwipe-Match-App: Skill for Codex

.agents/skills/feature-delivery/SKILL.md

feature-delivery is a skill for Codex from hoangsonww/PetSwipe-Match-App. It costs 58 tokens per session (300 once invoked), scanned A, original, MIT.

An end-to-end workflow for delivering features in the PetSwipe application across the frontend, backend, infrastructure, documentation, and validation.

In plain words
What is it for?
Use it for features that affect user-visible behavior, APIs, navigation, or several repository areas, including deciding which specialist should handle frontend, backend, infrastructure, documentation, or review work.
Why use it?
It prevents a cross-cutting feature from being implemented in only one part of the repository while related routes, APIs, navigation, tests, or documentation remain out of sync.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is hoangsonww/PetSwipe-Match-App's own configuration. It tells Codex how to work on PetSwipe-Match-App itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything PetSwipe-Match-App configures →

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

feature-delivery 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 12d 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

Use this skill when implementing or expanding a feature in PetSwipe.

Workflow

  1. Inspect the affected area before proposing structure.
  2. Decide whether the task is frontend-only, backend-only, infra-only, docs-only, or cross-cutting.
  3. Keep the change coherent across code, navigation, API behavior, validation, and docs.
  4. Validate with the smallest reliable command set for the touched area.
  5. Update docs when the task changes user-visible behavior, APIs, or deployment posture.

Delegation

If the task is broad, spawn the matching specialist agent:

  • frontend_ux
  • backend_api
  • infra_auditor
  • docs_curator
  • reviewer

PetSwipe Rules

  • Frontend work should preserve the Next.js Pages Router structure.
  • Backend work should keep routes, controllers, services, entities, and docs aligned.
  • Infra work should be validated with render and preflight commands, not claimed complete on inspection alone.
  • Doc updates should be made in the same task when behavior changes.

Read references/repo-map.md for structure and references/validation.md for command guidance.

Files

What ships with it

3 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.
