implement

implement is a skill for Claude Code from iwe-org/dev-workspace. It costs 66 tokens per session (751 once invoked), scanned A, original, MIT.

A workflow for carrying out an existing software implementation plan task by task. It keeps the plan aligned with the code by rechecking references, testing changes, and recording deviations.

In plain words
What is it for?
Use it when starting or continuing a feature or fix that already has an active plan. It helps select the plan, verify its code references, complete tasks, and update their status.
Why use it?
It prevents coding work from silently drifting away from the agreed plan. It also avoids building on unfinished prerequisite work.

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

implement 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.

The opening of the file, as written. The whole thing — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Implement a plan

Coding happens as it always does; this skill adds the discipline that keeps the plan document true while it happens. The plan is the source of truth: the code follows it, and where reality wins an argument, the plan is updated — never silently outgrown.

Steps

  1. Select the plan. Infer from conversation; if ambiguous, list the plans under ## Active in data/plans.md and ask (most recently created first). Announce: "Working on: — task N of M". No plan exists for what the user wants built? Stop and point at the plan skill.
  2. Load the context. Read the full plan, the specs in its ## Spec changes, and data/product.md ## Constraints and ## Authoring rules — they bind the code you're about to write.
  3. Check ## Depends on. Every prerequisite plan must carry stage: done; if one doesn't, say so and stop — building on an unshipped dependency is how two plans end up half-true.
  4. Re-verify the anchors. The plan's ## Key references line numbers were true when written; re-locate each symbol in the current checkout before relying on it. If lines moved, update the anchor list and its "verified as of" date — that edit is part of this session's work.
  5. Execute the next unchecked task. Follow its **Files:** list; write the code; run the tests that cover this task. When the task's work is done and its tests pass, tick its - [ ] → - [x] in the plan doc and iwe normalize.
  6. Write back deviations. If implementation reveals the ## Approach (or a task breakdown) is wrong, update the plan — amend the section, add or split tasks — before coding past the discrepancy, and tell the user what changed and why.
  7. Stop at a clean boundary. After each task (or more, if the user asked for a longer run), report progress — "3/5 tasks, next: " — and stop. Blocked mid-task? Leave the box unchecked, describe the blocker, and stop there instead.
  8. Finish. When the last box ticks, run the plan's ## Verification commands, report the results, and suggest the verify skill for the full pre-ship check, then the ship skill.

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 iwe-org/dev-workspace (10 stars, last pushed 2mo ago), licensed MIT. It adds 66 tokens to every session and 751 once invoked, about $0.0003 per session on Opus 5.5. 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.
