Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00082 | $0.00832 |
| Opus 5 | $0.00041 | $0.00416 |
| Sonnet 5 | $0.00016 | $0.00166 |
| Haiku 4.5 | $0.00008 | $0.00083 |
Grade A, and why
start-milestone scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.
<milestone_number>$ARGUMENTS</milestone_number>
Start Milestone
Transition a milestone from planning to active: bulk-update labels and Project board status.
API references: milestones.md | projects-v2.md
Arguments
<milestone_number/> — milestone number (required).
/start-milestone 3
Workflow
Step 1: Resolve Milestone
Call mcp__plugin_dh_backlog__backlog_list_milestones(state="open").
From the returned list, find the entry where number == <milestone_number/>.
If not found in the open list, call mcp__plugin_dh_backlog__backlog_list_milestones(state="all") and filter again.
If milestone is closed, report and stop.
If open_issues == 0, warn: "No open issues. Add items first with /group-items-to-milestone {number}"
Step 2: List Issues
Call mcp__plugin_dh_backlog__backlog_list_issues(milestone="{title}", state="open").
The response contains a list of issues with number, title, state, and labels fields.
Step 3: Confirm
Start milestone "{title}" — {N} open issues
Issues to transition (status:needs-grooming → status:in-progress):
#12 SAM: Error Recovery [priority:p1, status:needs-grooming]
#8 gitlab-skill: Remove URL [priority:p1, status:needs-grooming]
#14 create-backlog-item skill [priority:p2, status:needs-grooming]
Proceed?
Use AskUserQuestion with Yes / No options. Stop without changes if No.
Step 4: Bulk Label Transition
Use the Python automation script (preferred — avoids per-issue bash loops):
uv run .claude/skills/gh/scripts/github_project_setup.py milestone start \
--number {number}
Or, to preview changes without applying them:
uv run .claude/skills/gh/scripts/github_project_setup.py milestone start \
--number {number} --dry-run
The script removes status:needs-grooming and adds status:in-progress to each
open issue, creates the label if missing, reports per-issue results, and exits
non-zero if any issue fails.
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.

start-milestone is a skill published in the GitHub repository Jamie-BitFlight/claude_skills (66 stars, last pushed today), licensed MIT. It adds 82 tokens to every session and 832 once invoked, about $0.0004 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 2026-09-03.
