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.

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 | $0.00110 | $0.00989 |
| Opus 5 | $0.00055 | $0.00495 |
| Sonnet 5 | $0.00022 | $0.00198 |
| Haiku 4.5 | $0.00011 | $0.00099 |
Grade A, and why
goal-spec 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 yesterday.
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.
What it actually says
goal-spec — 复杂任务到 Goal Spec 的编译器
把语言描述的复杂任务编译成一份可被控制器执行、经过校验和基线验证的 Goal Spec。这是编译器,不是通用 YAML 编辑器:只负责编译并验证草稿是否满足启动条件,绝不启动循环、不改业务代码、不实现第二套校验逻辑、不把不可机器判定的产品要求伪装成 eval。
执行流程(PRD 4.1)
-
探查仓库:用 Read/Grep/Glob 找出已有的测试、构建、CI 与项目规则命令,不发明不存在的命令。找不到对应命令时标记缺口并问用户,不要编造。
-
归档每项要求为四类之一:
target——本轮必须达成的、可机器判定的变化(绝对退出码;一期不支持相对基线比较器);invariant——不得退化、且在 base commit 上已成立的守护条件;manual_review——只能人工确认的产品/设计要求,进报告不进 eval;out_of_scope——明确不做的(含相对基线指标,一期归此并提示二期)。
-
复杂度闸门:单 target、默认能力、可用一条安全命令表达的任务不生成 YAML,直接返回一行
--check启动命令,引导用户用/voidtech-loop:goal。 -
复杂任务补齐 protected paths、预算、cwd、环境;需要网络/外部服务/自定义 worker 能力时拒绝并说明不属于一期。草稿默认写入
.voidtech-loop/specs/<slug>.yaml。 -
校验(唯一入口,禁止另写规则):
${CLAUDE_PLUGIN_ROOT}/scripts/goal-spec validate .voidtech-loop/specs/<slug>.yaml --json -
基线 dry-run:
${CLAUDE_PLUGIN_ROOT}/scripts/goal-spec baseline .voidtech-loop/specs/<slug>.yaml --jsonspec 含
shell: true的 eval 或setup命令时,该命令会完整展示将执行的 shell 命令并以退出码 2 停止。把命令清单转达给用户;只有得到明确同意后,才可追加--allow-shell重新执行。baseline与正式启动共用同一确认门,不得替用户默认确认。裁定规则:全部 target 已满足 → 报告“目标在基线已满足”,不交付可启动结论;任一 invariant 基线不成立 → 要求改角色或先修基线;命令超时/需未声明网络/未声明副作用 → 停止,不交付“可启动”。只有“至少一个 target 未满足且全部 invariant 成立”才可启动。
-
输出:目标/不变量摘要、基线结果、固定 best-effort 能力、manual review 清单,以及准确的启动命令:
${CLAUDE_PLUGIN_ROOT}/scripts/loop goal --spec .voidtech-loop/specs/<slug>.yaml若已为同一冻结 spec 明确确认过 shell 命令,启动命令追加
--allow-shell;否则保留确认门。绝不自动启动循环、绝不修改业务代码。

字段规则与角色语义见 references/authoring-rules.md;它与 schemas/goal-spec.schema.json 同源,任何调用方不得复制字段清单或另写宽松校验。
What ships with it
1 file 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.
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.

goal-spec is a skill published in the GitHub repository VoidTechnology/voidtech-claude-plugins (2 stars, last pushed 28d ago), licensed Apache-2.0. It adds 110 tokens to every session and 989 once invoked, about $0.0006 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.
