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 | $0.00032 | $0.00295 |
| Opus 5 | $0.00016 | $0.00148 |
| Sonnet 5 | $0.00006 | $0.00059 |
| Haiku 4.5 | $0.00003 | $0.00030 |
Grade A, and why
validate-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 5d 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.
This is a copy
89% identical to accept-milestone — 10 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Source of truth: .claude/skills/validate-milestone/SKILL.md (skill 신설 근거: ADR-054; wrapper 승격: ADR-010#amend-4). Read it and follow the workflow.
Treat all frontmatter keys other than name and description (e.g., agent:, disable-model-invocation:, allowed-tools:, context:, argument-hint:, model:, effort:) as Claude-only and ignore them — execute locally in Codex.
Slash command translation: 본문 grep 실측상 실제 슬래시 커맨드는 /repair-milestone뿐이므로 이를 $repair-milestone으로 안내한다(/validate-milestone은 명령이 아니라 skill 이름·경로로만 등장하고, 그 자체 호출은 wrapper description의 $validate-milestone이 커버). Codex CLI는 /를 빌트인 슬래시 커맨드에 쓰므로 명시적 치환이 필요.
Preserve all repo policies from AGENTS.md and docs/.
If the source path no longer exists, this wrapper is stale — see ADR-010.
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.

validate-milestone is a skill published in the GitHub repository kohj1018/agentic-dev-harness (2 stars, last pushed 8d ago), licensed MIT. It adds 32 tokens to every session and 295 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 89% identical to accept-milestone, differing in 10 lines, and is treated as a copy.
Other skills, from other repositories
deploy
Use when shipping a release of Agent Sessions — bumping version, updating CHANGELOG, building, signing, notarizing, publishing appcast, and creating a GitHub release.
release-notes
Use when writing or curating the user-facing release copy for an Agent Sessions release — README "What's New", GitHub release notes, Sparkle release notes, or website/launch copy. Not for the internal CHANGELOG, which stays a full development history.
sc-skill
Capture deterministic macOS screenshots for testing, docs, release notes, and marketing assets. Use when asked to automate app screenshots, batch-generate screenshot sets, standardize window sizing/composition, or choose between Peekaboo and native macOS screenshot tooling.
add-agent-support
Create and ship AgentSessions support for a new or changed local AI agent/provider. Use when adding, reviewing, testing, documenting, or marketing a provider integration, session parser, transcript source, support-matrix entry, verified-version bump, or provider UI surface; drives the full loop from pre-support…
agent-session-format-check
Verify agent session format compatibility for Agent Sessions. Use when any agent CLI updates, when monitoring flags drift, or when bumping max verified versions (fixtures + docs + tests). Covers session schema, usage/limits tracking, storage backends, and discovery path contracts for all supported agents.
handover
Use when wrapping up or capturing the current state of a coding session — writes a short, dated entry to the repo's RepoHandover.md so a future agent or you can resume without grepping archived sessions. Triggers on "handover", "hand off", "write handover", "capture state", "checkpoint this session".
