What it does
Dev Implementation is an agent skill from codeaholicguy/ai-devkit. AI DevKit · Implementation phase guidance for executing feature plans and checking implementation against design. Use when the user wants to implement planned tasks, update implementation docs, verify code matches design, or run dev-lifecycle phases 5 and 7.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
The repository describes itself as: The control plane for AI coding agents. The licence is Apache-2.0.
When your agent uses it
- The user wants to implement planned tasks
- Update implementation docs
- Verify code matches design
- Run dev-lifecycle phases 5 and 7
Example prompts
- “/dev-implementation”
Requirements
- Node.js
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Run npx ai-devkit@latest lint before phase work.
- If working on a named feature, run npx ai-devkit@latest lint --feature .
- Read requirements, design, planning, implementation, and testing docs before changes.
- Use the tdd skill while executing implementation tasks: write a failing test before production code, then make it pass.
- Apply the verify skill before completing tasks or making implementation alignment claims.
- Keep testing and implementation docs in lockstep with code. Do not defer all doc updates to final verification.
- If parent dev-lifecycle established usable task tracing, emit phase, progress, next-step, blocker, and evidence events per task.
What it can do on your machine
Read from SKILL.md and the folder at commit 7ef0cd5. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Dev Implementation loads about 1.1k tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 567 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- AI DevKit · Implementation phase guidance for executing feature plans and checking implementation against design. Use when the user wants to implement planned tasks, update implementation docs, verify code matches design, or run dev-lifecycle phases 5 and 7.
Dev Implementation
Run implementation work for configured AI docs features. Before changing docs or code, propose the concrete plan for this phase and wait for user approval unless the user already approved the exact phase plan.
Phase Contract
- Run
npx ai-devkit@latest lintbefore phase work. - If working on a named feature, run
npx ai-devkit@latest lint --feature <name>. - Read requirements, design, planning, implementation, and testing docs before changes.
- Use the
tddskill while executing implementation tasks: write a failing test before production code, then make it pass. - Apply the
verifyskill before completing tasks or making implementation alignment claims. - Keep testing and implementation docs in lockstep with code. Do not defer all doc updates to final verification.
- If parent
dev-lifecycleestablished usable task tracing, emit phase, progress, next-step, blocker, and evidence events pertask.
Execute Plan
Use for Phase 5.
- Run
npx ai-devkit@latest lint --feature <name>and work through the planning doc path it validates. If manual path resolution is unavoidable, first resolve.ai-devkit.jsonpaths.docs, falling back todocs/ai. - Gather context: feature name, planning doc path, supporting docs, current branch, and current diff.
- Parse task lists and build an ordered queue by section.
- Present the task queue with status:
todo,in-progress,done,blocked. - For each task, show context, suggest relevant docs, and outline sub-steps from the design doc when useful.
- If task tracing is available, record current task progress and immediate next action per
task. - Reuse before writing: grep for existing utilities/functions before adding new ones. Reuse only if it fits cleanly.
- Subtract before adding: delete dead paths, redundant guards, stale tests, and one-caller wrappers when they are in task scope.
- Handle breaking changes carefully: update all in-repo callers atomically and delete the old internal API; for external/public/cross-service callers, add a new function and deprecate the old one.
- Model the domain when implementation friction repeats: replace synchronized flags, branch growth, or duplicated shape assumptions with the smallest domain structure that removes them.
- Generate a markdown tracking snippet after each status change.
- After each task, update the testing doc with completed scenarios, newly discovered scenarios, and invalidated scenarios. Update the implementation doc with changed files, decisions, design deviations, and edge cases handled.
- After each section, ask if new tasks were discovered.
- Summarize completed, in-progress, blocked, skipped, new tasks, task-tracing events emitted or why tracing was unavailable, and doc deltas.

Next: after completing any task, run dev-planning Phase 6. When all tasks are done, run Check Implementation, then dev-testing and dev-review.
Check Implementation
Use for Phase 7.
- Compare implementation against the configured design and requirements docs validated by
npx ai-devkit@latest lint --feature <name>. - Gather context: feature description, modified files, relevant design/requirements docs, constraints.
- Summarize design: key decisions, components, interfaces, data flows.
- Review file by file: verify design intent, note deviations, flag logic gaps, edge cases, security issues, and missing tests or doc updates.
- Treat repeated implementation friction as a redesign signal, not another patch, and return to design when the model no longer fits.
- Finalize the implementation doc. Verify it captures what shipped, fill gaps, and record follow-ups.
- Summarize alignment status, deviations with severity, missing pieces, concerns, and next steps.
Next: dev-testing, then dev-review. If major deviations exist, return to dev-design if design is wrong or Execute Plan if implementation is wrong.
