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 5.1 | $0.00046 | $0.01349 |
| Opus 5 | $0.00023 | $0.00674 |
| Sonnet 5 | $0.00009 | $0.00270 |
| Haiku 4.5 | $0.00005 | $0.00135 |
Grade A, and why
skill-manifest-sync 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 today.
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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill Manifest Sync
这是流程类 Skill，默认仅在用户显式调用 $skill-manifest-sync 时运行。
把仓库 config/skill-symlinks.yaml（推荐 user-scope 软链清单）落到当前电脑：创建缺失的软链、修复指向错误的软链、把指向本仓库但不在清单里的软链作为删除候选提示用户，并用本机白名单记录用户确认保留的例外。其他电脑 clone 本仓库后，执行一次即可获得与其他电脑一致的 skill 配置。
与 harness-config-sync 的边界：那个 skill 管多宿主之间的 prompt/skills 收敛（事实源 ↔ 各宿主入口）；本 skill 只管「本仓库清单 → user-scope（~/.agents/skills）」这一层软链，两者互补不重叠。
Skill Path（set once）
export AUTOREVIEW_SYNC="$PWD/common-skills/skill-manifest-sync/scripts/sync_skill_symlinks.py"
# 全局安装时：
export AUTOREVIEW_SYNC="$HOME/.agents/skills/skill-manifest-sync/scripts/sync_skill_symlinks.py"
$AGENTS_HOME 环境变量可以整体替换 user-scope 根目录（默认 ~/.agents）。
用法
# 预览本机与清单的差异，不改任何东西；有漂移时退出码 1
python3 "$AUTOREVIEW_SYNC" --mode check
# 执行同步；删除候选逐个交互提示（d 删除 / k 保留并加白名单 / n 跳过）
python3 "$AUTOREVIEW_SYNC" --mode apply
# 非交互（CI、脚本）：删除候选直接删除
python3 "$AUTOREVIEW_SYNC" --mode apply --yes
# 新增本仓库 skill 后登记清单（要求 skill 目录已存在于 common-skills/）
python3 "$AUTOREVIEW_SYNC" --mode register --skill my-skill --note "一句话用途"
# 登记外部项目 skill：项目须已在清单 sources 声明（缺省自动补一条）
python3 "$AUTOREVIEW_SYNC" --mode register --source mattpocock-skills --skill handoff --note "一句话用途"
# 删除/重命名 skill 后清理清单
python3 "$AUTOREVIEW_SYNC" --mode remove --skill my-skill
依赖 PyYAML（pip install pyyaml）；缺失时脚本以退出码 2 给出安装提示。
外部项目来源
清单 sources: 只声明项目名（如 mattpocock-skills），条目用 source: <项目名> 指向它，绝不写机器绝对路径。外部项目里的 skill 约定位于 skills/<bucket>/<name> 且含 SKILL.md，脚本自动定位；同名出现在多个 bucket 视为歧义，保守失败。项目根按序解析：
$SKILL_SOURCE_<NAME>_DIR（项目名大写、-转_，如SKILL_SOURCE_MATTPCOCK_SKILLS_DIR）$SKILL_SOURCES_DIR/<项目名>- 本仓库 checkout 的同级目录
<项目名>
解析不到时相关条目按 stale 报告，不自动 clone。其他电脑只需把外部项目 clone 到本仓库同级目录（或设置上述环境变量）即可复现同一套配置。
报告类型
| 类型 | 含义 | apply 行为 |
|---|---|---|
ok |
软链与清单一致 | 无 |
create |
清单要求但本机缺失 | 创建软链 |
fix |
软链指向本仓库内的错误位置（或死链） | 修复为清单目标 |
extra |
指向本仓库但不在清单里的软链 | 交互提示删除；k 写入白名单 |
conflict |
目标位置被真实目录或指向其他仓库的同名链接占用 | 不动，报告后由用户手动裁决 |
stale |
清单条目指向不存在的 skill 目录，或来源项目解析不到 | 不动，报告后用 --mode remove 或补目录/clone 项目 |
What ships with it
5 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.
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.

skill-manifest-sync is a skill published in the GitHub repository hxy91819/mason-skills (2 stars, last pushed today), licensed MIT. It adds 46 tokens to every session and 1,349 once invoked, about $0.0002 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 2026-09-04.
