task-verification

task-verification is a skill for Claude Code, Codex from BuildrAI/Buildr. It costs 78 tokens per session (4,375 once invoked), scanned A, original, MIT.

A verification workflow for checking whether a software task works as intended and recording the current results. It also maintains a project's written declaration of what can be verified, subject to the required review process.

In plain words
What is it for?
Use it to inspect, run, reconcile, or record verification for a task, and to maintain verification capability declarations when authorized.
Why use it?
It provides a defined boundary and durable record for test or verification results instead of relying on informal checks.

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

task-verification 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 3d 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.

Task Verification Skill

本 Skill 是 buildr.task-verification/v3 的默认 provider。它只负责两部分:Project 的 Verification Capability Declaration,以及针对正式 Task 目标的 transient Execution + Workspace本地current Result。它不开发测试,不拥有 Task Environment、Task Review、Task Development、Candidate generation、Task progression、风险接受、部署或业务验收。

开始行动时必须读取 references/project-verification-v3.md;只有经declaration-intake完成只读发现、展示精确diff,并形成routine-maintenance结论或取得长期适用性变化的用户授权后,才使用templates/project-verification.yml维护长期声明。不得绕过Intake分类、静默扩大scope/target或伪造capability。正式 Result 必须通过 Task Verification Application 维护,不能直接读写Workspace SQLite或旧.buildr/tasks/<task-id>/verification.yml

1. 建立验证边界

先确认:

  • 正式 Task ID、Intent、Project/Service/Project-bound Change scope 和 active 状态,并计算三者所属Project的去重排序并集;
  • canonical Workspace,以及由 Task Environment 交接的实际 execution root;
  • 当前交付目标的明确、稳定 target identity 和可移植 summary;
  • current Task Candidate identity/generation(正式execution、inspect与reconcile必需;Task外transient execution不使用);
  • operation:inspectexecutereconcile、仅工作区record 或 transient cleanup
  • Task有效Project集合内每个 Project 当前 verification.yml,以及实际变更路径、条件、环境和副作用;有效Project集合为空时明确采用仅工作区分支。

没有正式 Task 时可以按用户要求执行已有测试并报告 transient 事实,但不得伪造 Task Result。没有稳定 target identity 时可以 inspect 为 unknown,不能 record。

先运行:

buildr task verification inspect <task-id> \
  --candidate-identity <candidate-identity> --candidate-generation <n> \
  --target-identity <identity> --target <canonical-workspace> --json

current Result只有在Candidate identity/generation、target与全部declaration identities都current时才适用于当前目标。任一当前identity未提供为unknown;Candidate、声明缺失/出现、内容、path或Project scope变化为stale。合法v1 Result只读兼容并明确显示legacy-result-candidate-unbound,不能用于新Candidate gate。不要写回applicability标记或回填旧Result。

当前目标来自ready Task Environment且其中的declaration bytes尚未进入canonical Workspace时,只在reconcile(或仅工作区record)追加--declaration-root <task-environment-root>。Application只在正式写入动作中观察该Task当前ready Environment的精确根目录;inspect不接受路径,只比较调用方显式提供的保存identity。本机路径不进入current Result。

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

task-verification is a skill published in the GitHub repository BuildrAI/Buildr (24 stars, last pushed 4d ago), licensed MIT. It adds 78 tokens to every session and 4,375 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.
