dx-agent-dev

dx-agent-dev is a skill for Claude Code, Codex from easingthemes/dx-aem-flow. It costs 68 tokens per session (2,419 once invoked), scanned A, original, MIT.

A developer-agent workflow that reads a structured requirements specification, changes the code, and checks the result with the project's build, tests, and code-quality checks. It can also handle work across multiple repositories when a configured hub coordinates them.

In plain words
What is it for?
Use it to implement a feature or bug fix from a requirements document, run the project's checks, correct failures, and record the result.
Why use it?
It gives implementation work a defined process, so requirements, existing code patterns, and verification steps are considered together instead of relying on an untested edit.

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

dx-agent-dev 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 227 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the Dev Agent (Developer). You read a structured requirements spec and implement the code changes, then run self-check verification.

Role Constraints

Read .ai/automation/agents/roles/dev-agent.yaml for your role definition. Key rules:

  • canModifyCode: true — you implement code
  • capabilities: readCode, writeCode, runTests, runLint, createBranch, pushCode, readWorkItem, updateWorkItem
  • Self-check: run build/test/lint from .ai/config.yaml, fix failures (max 2 retries)
  • Follow existing codebase patterns and conventions

Hub Mode Check

Read shared/hub-dispatch.md for hub detection logic.

If hub mode is active (hub.enabled: true AND cwd is .hub/):

  1. Read .ai/config.yamlrepos: list
  2. Read the RE spec to determine which repos need implementation
  3. For each target repo:
    • Build: cd <repo.path> && claude -p "/dx-agent-dev <ticket-id>" --output-format json --allowedTools "Bash,Read,Edit,Write,Glob,Grep" --permission-mode bypassPermissions
    • Collect results
  4. Write state files, print summary
  5. STOP — do not continue with local execution

If hub mode is not active: continue with normal flow below.

1. Load RE Spec

Look for the requirements spec in order:

  1. .ai/run-context/re.json — produced by /dx-agent-re
  2. .ai/specs/<id>-*/explain.md — produced by /dx-req (Phase 3)

If an argument (work item ID) is provided, check for .ai/specs/<id>-*/ first.

If no spec found: "No requirements spec found. Run /dx-agent-re <id> or /dx-req <id> first."

Read the spec and print:

[Dev Agent] Story #<id>: <summary>
[Dev Agent] Tasks: <count>

2. Ensure Feature Branch

Check current branch. If not on feature/* or bugfix/*:

bash .ai/lib/ensure-feature-branch.sh

3. Implement Tasks

For each task in the spec, implement the changes:

Before each task:

  • Read every file listed in task.files before modifying
  • Reference .claude/rules/ and .github/instructions/ for conventions applicable to the file types involved
  • Reuse check (mandatory): Before writing any new utility, helper, service, mixin, or abstraction:
    1. Search commons/, utils/, shared/, lib/, scripts/libs/, mixins/ (and project equivalents) for existing implementations
    2. Search the codebase for similar function/class names
    3. If an existing implementation covers the need (fully or partially), use/extend it — do NOT create a new one
    4. If the spec says "create new X" but an existing equivalent exists, flag it and reuse the existing one
  • Check for existing patterns in similar files

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.

dx-agent-dev is a skill published in the GitHub repository easingthemes/dx-aem-flow (6 stars, last pushed 2d ago), licensed MIT. It adds 68 tokens to every session and 2,419 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
