neo-harness-project

neo-harness-project is a skill for Claude Code, Codex from Benknightdark/neo-skills. It costs 93 tokens per session (2,564 once invoked), scanned A, original, MIT.

A guide for assessing a software project and building a complete, evidence-based engineering support system around it. This system can include project knowledge, plans, verification, and recovery information.

In plain words
What is it for?
Use it to inspect a project, identify missing engineering assets, preview proposed file changes, build approved documentation or checks, and verify or recover the result.
Why use it?
It prevents teams from adding generic documents or checks that do not match the project's real tools, structure, or needs.

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

neo-harness-project 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 6d 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.

Project Harness Builder

依專案現況建立可閱讀、可驗證、可恢復的工程環境。不得套用固定技術棧或理想架構,也不得建立沒有真實檢查能力的空殼。

邊界

  • 本技能盤點並建置整個專案的 Harness。
  • 需求只涉及 AGENTS.md 時,改用 neo-harness
  • 目標專案的 Harness 資產必須集中在根目錄 .neo_harness/;唯一例外是必須留在根目錄的 AGENTS.md
  • 技能套件自身的 references/assets/evals/ 是技能實作資源,不屬於目標專案的 Harness 產出位置。
  • 不得新增使用者未要求的第三方依賴、服務、部署或外部連線。
  • 技能內容與產出必須保持供應商中立,不得提及任何特定模型供應商、產品、套件族、官方網址或供應商專屬中繼資料。
  • 若無法在遵守中立要求的前提下準確記錄必要專案事實,停止相關產出並回報衝突;不得刪減或改寫事實以規避衝突。

Harness 資產位置規範

下列路徑均以目標專案根目錄為基準:

資產 正式路徑
專案入口與工作規則 AGENTS.md
架構文件 .neo_harness/ARCHITECTURE.md
計畫規範 .neo_harness/PLANS.md
專案命令清單 .neo_harness/docs/scripts.md
進行中的執行計畫 .neo_harness/docs/exec-plans/active/
已完成的執行計畫 .neo_harness/docs/exec-plans/completed/
  • 不得建立 .neo_harness/AGENTS.md;根目錄 AGENTS.md 是唯一的 Agent 入口。
  • 所有其他 Harness 核心或條件式資產都必須放在 .neo_harness/ 內,並由根目錄 AGENTS.md 或相關文件連結。
  • .neo_harness/ 是正式且應納入版本控制的專案資產;若被 .gitignore 或其他忽略規則排除,先標記為 blocked,不得自行修改忽略規則。
  • 不得把非 Harness 文件、既有專案文件或技能套件自身的資源移入 .neo_harness/

既有舊路徑的搬遷

若盤點發現下列舊路徑存在,必須先提供搬遷預覽並取得使用者對精確清單的明確確認:

舊路徑 正式路徑
ARCHITECTURE.md .neo_harness/ARCHITECTURE.md
PLANS.md .neo_harness/PLANS.md
docs/scripts.md .neo_harness/docs/scripts.md
docs/exec-plans/ .neo_harness/docs/exec-plans/
  • 搬遷預覽必須列出來源、目的地、受影響的連結或索引、驗證命令與復原方式。
  • 目的地已存在、來源與目的地內容衝突,或目的地受忽略規則排除時,動作標記為 blocked;不得覆寫、刪除、建立重複副本或建立符號連結。
  • 未經確認不得搬遷、批次改名或刪除舊路徑;確認後才可更新受影響的 Harness 連結,並保留可從版本控制或已報告快照復原的依據。
  • 不屬於上述清單的舊文件不自動搬遷,除非使用者另行確認。

必要流程

1. 盤點,不寫入

先讀取專案規範、版本控制狀態、根目錄、套件與建置設定、測試、CI、文件、主要入口及現有 Harness 資產,包括 .neo_harness/ 正式路徑與上述舊路徑的既有檔案。命令必須來自可驗證的設定或文件,不得依技術棧猜測。

盤點時必須閱讀 專案評估模型,依來源證據判定成熟度與缺口。未知資訊標為「未知」,不得補成理想狀態。

2. 選擇產出

閱讀 資產選擇矩陣,將候選路徑分類為:

  • create:路徑不存在,且已有足夠證據建立。
  • update:保留有效內容並補齊缺口。
  • rebuild:現有內容與已確認目標衝突,需重建。
  • migrate:舊 Harness 路徑存在,需依確認結果搬到 .neo_harness/ 並更新受影響連結。
  • skip:沒有需求或證據,不建立。
  • blocked:缺少關鍵事實或違反中立要求。

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.

neo-harness-project is a skill published in the GitHub repository Benknightdark/neo-skills (7 stars, last pushed 6d ago), licensed MIT. It adds 93 tokens to every session and 2,564 once invoked, about $0.0005 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.
