tech-implement

tech-implement is a skill for Claude Code, Codex from nanparth/ai-skill-hub. It costs 78 tokens per session (1,229 once invoked), scanned A, original, MIT.

A workflow for carrying out software changes through isolated work, test-driven development (writing tests before implementation), review, and verification.

In plain words
What is it for?
Use it to implement planned features, fix bugs, debug systematically, finish existing branches, and run tests before delivery.
Why use it?
It organizes implementation into checks that help catch mistakes and confirm the finished change works.

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

tech-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 4d 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 — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.

tech-implement

Execute implementation plans or bug fixes with TDD, isolated work, subagent review, and verification gates.

Required Dependencies

  • Git.
  • Shell access.
  • A runnable project test command such as pytest, npm test, cargo test, or a user-provided command.
  • Subagent support for the full pipeline. Without subagents, follow the checklists manually and do one task at a time.

Optional: GitHub CLI (gh) for pull request creation. If gh is unavailable, push the branch manually or provide PR instructions instead.

Routing

Intent Action
User has a plan file or tech-blueprinting output to execute Load workflows/execute-plan.md
User reports a bug or test failure needing a fix Load workflows/fix-bug.md
User wants systematic debugging without committing to a fix Load workflows/systematic-debugging.md
User wants to finish a branch already in progress Load workflows/finish-branch.md

If intent is ambiguous, ask whether this is a plan to execute, a bug to fix, or in-progress work to finish.

Pipeline Overview

Feature from plan:
  plan -> task extraction -> worktree -> per-task loop -> final review -> finish -> optional docs

Per-task loop:
  implementer subagent -> spec reviewer -> quality reviewer -> verification gate -> mark complete

Bug fix:
  bug report -> worktree -> systematic debugging -> synthetic task -> per-task loop -> finish

Core Principles

  • Agents receive full task text inline. They do not read the plan file.
  • Fresh subagent per task. No conversation context is inherited.
  • TDD is mandatory. No production code without a failing test first.
  • Two-stage review is mandatory: spec compliance first, code quality second.
  • Verification is a gate. Run commands, read output, and check exit codes before claiming completion.
  • Implementer dispatches are sequential only.
  • Worktree isolation is the default for normal Git repositories.
  • One responsibility per module. Use explicit interfaces.

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.

tech-implement is a skill published in the GitHub repository nanparth/ai-skill-hub (23 stars, last pushed 12d ago), licensed MIT. It adds 78 tokens to every session and 1,229 once invoked, about $0.0004 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 2026-08-30.
