codex-harness-javascript: Skill for Codex

.agents/skills/frontend-planning/SKILL.md

frontend-planning is a skill for Codex from thuandiep1707/codex-harness-javascript. It costs 57 tokens per session (508 once invoked), scanned A, original, MIT.

A planning workflow for turning frontend requirements into Jira work items: a Feature, functional Tasks, and specialist Subtasks. Jira is a project-tracking system, and the workflow stops before anyone starts coding or testing.

In plain words
What is it for?
Use it when a frontend request needs analysis, project-stack discovery, Jira decomposition, and verified work-item creation without dispatching design, coding, test-plan, or testing specialists.
Why use it?
It structures frontend work and keeps planning separate from implementation, while requiring the human-facing Jira content to be written in Vietnamese.

Skill for Codex

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

This is thuandiep1707/codex-harness-javascript's own configuration. It tells Codex how to work on codex-harness-javascript 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 codex-harness-javascript 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

frontend-planning 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 1mo 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.

Frontend Planning Workflow

This is a user-facing planning-only workflow. Main is the runtime Orchestrator.

Scrum Master planning and replan dispatches must use the operation-specific runtime profile defined by the Main orchestration contract in AGENTS.md.

Scope

  1. Main resolves the working product repository, execution intent plan-only, and current Jira-backed lifecycle entry.
  2. Main dispatches Brain for requirement analysis, authority readiness, and lightweight project-stack discovery when NEW or REPLAN requires it.
  3. Capture Brain result, close/verify Brain, and continue only when analysis-status: ready and authority.status: ready.
  4. Main dispatches Scrum Master with operation planning or replan, execution intent plan-only, and the approved analysis.
  5. Scrum Master discovers the current Jira project schema, resolves semantic work roles to actual Jira work types/fields/relationships, creates or reconciles the Jira work graph, and returns compact jira-work-report.
  6. Main closes/verifies Scrum Master and validates that the returned work graph is usable for later execution/resume.
  7. Stop before Design, Test Plan, Coding, Testing Logic, or Testing UI execution.

Planning rules

  • Decompose requirement -> user outcomes -> functional slices -> specialist execution units.
  • Treat work-container as optional grouping/context, not a required Jira issue type.
  • Resolve actual Jira work types, fields, options, relationships, and workflow states from the current project schema.
  • Do not split primarily by files, components, hooks, technical layers, or agent roles.
  • Human-facing Jira content must be Vietnamese; technical identifiers remain exact.
  • Detect project implementation stack from evidence; detection is not permission to adopt a new dependency.
  • Record unresolved technology/architecture decisions instead of defaulting to a library.
  • Main owns workflow/lifecycle decisions and child dispatch. Scrum Master alone owns Jira decomposition/schema-resolution/mutation for this workflow.

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.
