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 | $0.00053 | $0.02194 |
| Opus 5.5 | $0.00021 | $0.00878 |
| Sonnet 5.5 | $0.00011 | $0.00439 |
| Haiku 4.5 | $0.00005 | $0.00219 |
Grade A, and why
issue-graph 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Issue Graph — 确定性 issue 关系图（原生边 + 图计算 + 并发原语）
Repo profile — read
.claude/repo-profile.mdfirst. This skill is repo-agnostic; arc is the reference implementation. It resolves the repo from the git remote (repo_slug); its runtime scripts are referenced as<plugin_root>/skills/issue-graph/scripts/*.ts(the profile'splugin_root— so they resolve wherever the plugin is checked out). Arc's own issue-number provenance for any lessons is not inlined here.
「选择和传播都是纯计算，LLM 只负责做，不负责猜该做谁。」
GitHub 原生图（sub-issues + issue dependencies）是关系数据的唯一真相；本 skill 提供四个确定性脚本，把「哪些 issue 现在能做 / 哪些父 issue 该收尾 / 哪些 issue 被某次关闭解锁」从模型猜测变成每轮现算的图计算。图不落盘——唯一持久状态是 GitHub 本身，所以永远没有索引漂移。
设计来源、Phase 0 演练证据（149 条边、17 个 rollup 候选、fencing 实测）、并发 设计全文见 arc case-law 附录（repo-profile Case Law）。
脚本（scripts/，全部 REST-only + 手动分页）
为什么 REST-only：cloud routine 的出站代理挡
gh的 GraphQL（403 "not enabled"），--paginate对 issues 端点也有代理 bug（根 CLAUDE.md「按需安装 CLI 依赖」节）。所有脚本手动page=N循环，在本地与 cloud routine 行为一致。
graph-scan.ts — 图计算（只读，sweep 每轮调）
bun <plugin_root>/skills/issue-graph/scripts/graph-scan.ts [--window-hours 2] [--pretty]
输出 JSON：
| 字段 | 语义 | 消费方怎么用 |
|---|---|---|
ready |
open ∧ 无 open blocker；顺序已按 hostname 旋转（多机错峰） | 并入 sweep 候选集；hasHold=true 的按 hold 语义处理 |
blocked |
有 open blocker 的 issue + blocker 列表 | 确定性 SKIP（带原因），不再靠模型猜「轮没轮到」 |
rollupCandidates |
open ∧ 有孩子 ∧ 全部孩子已关 | 走 issue-review 的父级 rollup（fencing 互斥） |
kicks |
近窗口关闭的 issue 反查出的 open parent / 被解锁 dependent | 无需人类 comment 直接注入候选集——这就是修「子 issue 完成后要人 bump」的机制 |
窗口默认 2h > sweep 间隔 1h：同一关闭事件被两轮看见没关系，kick 只是注入候选， 后续统一走 terminal-comment 去重 + 锁 + 认领检查，重复注入零成本。
link.ts — 写边（幂等，开派生 issue 时必调）
bun <plugin_root>/skills/issue-graph/scripts/link.ts --parent <N> --child <M> # 父子边
bun <plugin_root>/skills/issue-graph/scripts/link.ts --issue <Y> --depends-on <X> # 依赖边
写边纪律（图精确性的来源）：agent 每开一个 spin-off / 派生 issue，除了 body
里的 <!-- spinoff-of: #N --> 标记（留作 provenance），必须同时调 link.ts
挂原生父子边；phase 之间有硬次序的加 --depends-on。边已存在 = 幂等 OK；child
已有不同 parent = 报错停下（换 parent 是人类决定）。人手开的 issue 不带边也
没关系——孤立点走现有 label/catch-all 通道，图只增强、不替代。
What ships with it
7 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.

issue-graph is a skill published in the GitHub repository ArcBlock/agent-skills (5 stars, last pushed 9d ago), licensed MIT. It adds 53 tokens to every session and 2,194 once invoked, about $0.0002 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.
