A task-implementation workflow for projects that organize work into phases, backlogs, and acceptance criteria.

Use it to implement a listed task, write related unit tests, run the project’s checks, and mark completed acceptance criteria.

It gives the coding agent a defined process for finding the requested task, following project rules, and checking the result with type checks, linting, and tests.

implement — Skill for Claude Code by natthasath

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add natthasath/natthasath-marketplace --skill implement

Clone the repo

git clone --depth 1 https://github.com/natthasath/natthasath-marketplace

Made for: Claude Code.

Or install projects, the plugin that ships this one along with the rest of its 15 skills.

Per session 53 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 593 The whole file, excluding the scripts and references it only reads on demand.

Security scan B 1 finding. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00053	$0.00593
Opus 5	$0.00026	$0.00296
Sonnet 5	$0.00011	$0.00119
Haiku 4.5	$0.00005	$0.00059

Measured 9d ago against content hash c4d698b1a92c, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-09, from the pricing page.

Security

Grade B, and why

implement scanned grade B with 1 finding 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 9d 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

What it actually says

!cat .claude/config/tech-stack.md .claude/config/current-phase.md context/tasks/in_progress/current_sprint.md 2>/dev/null

Implement task: $ARGUMENTS

อ่าน phase: จาก config ด้านบน แล้วเปิด context/tasks/backlog/phase_<N>_*.md เพื่อหา task $ARGUMENTS
- ถ้าหา task ไม่เจอใน phase ปัจจุบัน ให้สแกน backlog ทุก phase
- ถ้าไม่เจอเลย ให้แจ้ง error และหยุด
ตรวจสอบว่า task นี้อยู่ใน current_sprint.md แล้ว (status: 🔄 In Progress)
- ถ้ายังไม่อยู่ ให้แจ้ง "รัน /start-task $ARGUMENTS ก่อน" แล้วหยุด
Implement ตาม Description และ Acceptance Criteria โดยยึดหลัก:
- Architecture ตาม CLAUDE.md
- Coding standards ตาม .claude/rules/coding-standards.md
- เขียน unit tests ควบคู่กับ implementation
หลัง implement เสร็จ รันตรวจสอบตามลำดับ (ใช้ commands จาก tech-stack.md ด้านบน):
- typecheck command
- lint command
- test command
ถ้ามี error — แก้ให้ผ่านก่อนทุกกรณี อย่ารายงานว่าเสร็จจนกว่าทั้ง 3 คำสั่งจะ pass
อัปเดต Acceptance Criteria ใน backlog file:
- เปลี่ยน - [ ] เป็น - [x] สำหรับทุกข้อที่ implement เสร็จแล้ว
- ข้อที่ยังไม่เสร็จให้คง - [ ] ไว้

สรุปผล:

✅ Acceptance Criteria แต่ละข้อ — pass หรือ pending
⚠️ สิ่งที่ยังค้างหรือต้องทำต่อ (ถ้ามี)

ถ้า criteria ครบทุกข้อ ปิดท้ายด้วย:

─────────────────────────────────────
ถัดไป → /ship $ARGUMENTS
─────────────────────────────────────

ถ้ายังมี criteria ค้าง ปิดท้ายด้วย:

─────────────────────────────────────
ถัดไป → /implement $ARGUMENTS   (criteria ยังไม่ครบ)
─────────────────────────────────────

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.

implement is a skill published in the GitHub repository natthasath/natthasath-marketplace (1 stars, last pushed yesterday), licensed MIT. It adds 53 tokens to every session and 593 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
