Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 5.1 | $0.00110 | $0.00989 |
| Opus 5.5 | $0.00044 | $0.00396 |
| Sonnet 5.5 | $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 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.
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 5d ago), licensed Apache-2.0. It adds 110 tokens to every session and 989 once invoked, about $0.0004 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.
