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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00100 | $0.01578 |
| Opus 5 | $0.00050 | $0.00789 |
| Sonnet 5 | $0.00020 | $0.00316 |
| Haiku 4.5 | $0.00010 | $0.00158 |
Grade A, and why
milestoneplan 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 4d 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 — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
milestoneplan
Show a milestone's execution plan as one table. This skill never writes: no issue edits, comments, PRs, or Workflow runs. Fixes belong to execution-plan-review; the run belongs to milestone-workflow.
Input
A milestone title (v1, v1 — Desktop core call loop), matched loosely on prefix. With no input, or when two titles match, list the open milestones with open/closed counts and ask which.
Steps
1. Read the milestone
gh api "repos/{owner}/{repo}/milestones?state=all&per_page=100" --paginate --jq '.[] | "\(.title) [\(.state)] — open:\(.open_issues) closed:\(.closed_issues)"'
gh issue list --milestone "<title>" --state all --limit 500 --json number,title,state,body
state=all and --paginate with per_page=100 are required: the defaults are open-only and 30 per page, so a closed or late milestone reads as not found. If the issue count equals --limit, re-fetch at a higher limit until a fetch returns strictly below its own limit. Strip \r from bodies (the API returns CRLF), then parse the [C<score>] title prefix and the ## Execution block: Depends on, Runs after, build model, effort, fableplan, PR review:, and the optional Validate effort: and Plan effort: lines.
2. Render the table
Output is exactly one pipe-delimited markdown table, one row per issue ordered by number, capped at these 8 columns so terminals do not wrap it:
| # | Description | C | Deps/After | Validate | Build | Plan | Review |
|---|
- Description — the title with the
[C<score>]prefix stripped, truncated to ~30 characters. - C — the score from the title prefix.
- Deps/After —
<depends> / <after>, issue numbers without#,nonerendered as—(e.g.12, 13 / —); never infer edges from prose. When everyRuns afterisnone, drop the/ —suffix and say so in the note. - Validate —
<model> · <effort>. The model comes from the score band, never from a stamp; the effort is the band default unless aValidate effort:line stamps one. Band defaults:Opus 5 · mediumat[C0]–[C9],Opus 5 · highat[C10]–[C49],Opus 5 · xhighat[C50]–[C70],Fable 5.1 · mediumat[C71]–[C80],Fable 5.1 · highat[C81]and above (validate-issuestep 6 is the authority; a missing prefix routes as Fable high). A stamped tier renders as the effective value plus(stamped), e.g.Fable 5.1 · xhigh (stamped); the pipeline clamps an Opus row stampedlowormediumtoOpus 5 · high (stamped <tier> → high: Fable-only tier)and applies no clamp to a Fable row stampedxhigh. - Build — the stamped
<model> · <effort>, e.g.Opus 5 · xhigh. An external harness renders as<Name> · <effort> (<harness>), e.g.Luna · max (Codex CLI)orGrok · high (Cursor CLI, cursor-grok-4.6-high)when the stamp carries a model id.maxis Codex CLI-only, so a Cursor or Claude row stampedmaxrenders the clamp the pipeline applies, e.g.Grok · xhigh (Cursor CLI, stamped max → xhigh). - Plan —
Yes · <effort>when fableplan isYes: the stampedPlan effort:tier with(stamped), elsehigh. PlainNowhen stampedNo; aPlan effort:line on aNoissue rendersNo · <tier> (inert — no plan stage runs). - Review — the first-review trigger from the
validate-issuestep 6 first-review table (this file states no boundary of its own; a missing prefix takes its heaviest row), unlessPR review:stamps an explicit@claude <model> review effort:<tier>trigger. Render a stampedhaikuas@claude sonnet review, the trigger the runtime posts, becauseclaude.ymladmits onlysonnet/opus/fable. Append a parenthetical only for a real caveat (e.g.may close with no PR).
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.

milestoneplan is a skill published in the GitHub repository richkuo/rk-skills (49 stars, last pushed today), licensed MIT. It adds 100 tokens to every session and 1,578 once invoked, about $0.0005 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.
