codex-harness-javascript: Skill for Codex

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

frontend-delivery is a skill for Codex from thuandiep1707/codex-harness-javascript. It costs 67 tokens per session (1,080 once invoked), scanned A, original, MIT.

A user-facing workflow for carrying frontend work from project analysis through Jira planning, specialist implementation, testing, cleanup, and final approval.

In plain words
What is it for?
Implementing frontend changes end to end, coordinating child agents, making Jira calls, checking results, and stopping only at acceptance or a real blocker.
Why use it?
It keeps a large frontend task moving across its required stages and supports starting, resuming, replanning, pausing, and accepting work.

Skill for Codex

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

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-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 7d 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 Delivery Workflow

This is a user-facing workflow entry point. It coordinates agents; it does not contain implementation knowledge.

Intent

Run continuously from the smallest valid workflow entry until acceptance, pause, or a real blocker. Do not stop merely because Jira Tasks/Subtasks were created.

Entry resolution

Resolve the current entry before spawning agents:

  • NEW: no valid Jira workflow exists for the requested work.
  • RESUME: valid Jira analysis/task tree exists and relevant requirements are unchanged.
  • REPLAN: relevant requirements or approved architecture changed materially.
  • PAUSE: the user explicitly asks to stop/pause an active workflow.
  • ACCEPTANCE: executable work is complete and final acceptance is due.

Natural-language pause intent such as dừng lại, tạm dừng, để mai làm tiếp, or equivalent must route to PAUSE.

Controller execution rule

The Primary Controller owns runtime transport for the whole workflow:

  • native child-agent spawn/retry/interrupt/close/verification;
  • Jira connector calls requested by Orchestrator;
  • cross-agent runtime-resource cleanup supervision.

Orchestrator owns workflow decisions. It must not call native agent lifecycle APIs or Jira directly. It returns controller-actions; the Primary Controller executes them exactly and returns confirmed results to the same Orchestrator child.

Keep one Orchestrator child alive across the active delivery workflow. Do not restart it after every Coding/Testing result.

Continuous delivery

For NEW:

  1. Primary Controller spawns Brain for bounded requirement analysis and project-stack discovery.
  2. Capture Brain result, then explicitly close and verify the Brain child.
  3. Primary Controller spawns one Orchestrator child in planning mode with execution intent deliver and supplies the approved analysis/Jira context.
  4. Orchestrator returns status: awaiting-controller with exact jira-call and/or dispatch-specialist actions as needed.
  5. Primary Controller executes those actions without changing their intent/payload and sends confirmed action results back to the same Orchestrator child.
  6. For dispatch-specialist, Primary Controller applies the native retry policy, collects the specialist result/runtime-resource evidence, ensures owned resources are cleaned, explicitly closes/verifies the specialist child, then returns the result to Orchestrator.
  7. Repeat the controller-action loop until Orchestrator returns a terminal reconciliation result with acceptance inputs ready.
  8. Close and verify the Orchestrator child.
  9. Spawn Brain for final acceptance, then close/verify the Brain acceptance child before reporting the workflow complete.

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.
