upgrade-readiness-brief

upgrade-readiness-brief is a skill for Claude Code, Codex from gke-labs/kube-agents. It costs 83 tokens per session (1,950 once invoked), scanned A, original, Apache-2.0.

A read-only skill that creates a weekly upgrade-readiness brief from a recorded review and a findings queue. It focuses on issues that need the user's decision and points to the full report.

In plain words
What is it for?
It is for reporting cluster upgrade blockers, risks, newly reported or resolved findings, project failures, and the location of the complete weekly report.
Why use it?
It turns the review's stored findings into a fixed-format decision brief without changing findings, making upgrades, or deciding actions.

Token cost

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.

Security

Grade A, and why

upgrade-readiness-brief 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.

upgrade-readiness-brief — The Week's Decisions, On Request

The Saturday job upgrade-readiness-weekly-review grades every cluster and registers each blocker and risk on the findings queue; the job upgrade-readiness-weekly-brief composes the week's brief from both under /opt/data/profiles/platform/governance/upgrade_readiness_brief_sop.md. This skill is that SOP's "On request" route: a user asks for the brief, or for what needs their decision, or for this week's report, and gets the same shape in chat. Read only. Register nothing, decide nothing, upgrade nothing.

Steps

  1. Read the review's copy:
    • cat /opt/data/upgrade-readiness/weekly/latest.json — the summary: generated_at, projects, clusters (reviewed, blocked, ready, unknown, unread), counts, findings (rows with id, severity, check, entry, project, cluster, namespace, object, title, action, outcome), new_ids, suppressed_ids, no_longer_reported_ids, project_failures, registration_errors, report_path.
    • cat /opt/data/upgrade-readiness/weekly/latest.md when a line needs more than the row says.
    • If the asked-for thing is the report, print latest.md as it is and stop; when the file is missing, say the review's copy is not there (the weekly review has not run, or its copy did not land; the review's own chat line, if any, says which) and offer the on-request readiness report (fleet-upgrade-verification, --readiness) instead of composing anything.
    • If generated_at is older than 48 hours, compose from the summary anyway and say its date and age in the headline: a stale brief with its date beats none.
    • If the file is missing, read the queue first (step 2). When it holds upgrade- rows, the review ran and its copy did not land: compose from the queue alone, with a headline that says the summary is unavailable, and leave out the counts only the summary gives. Only when the queue holds no upgrade- rows either compose a live brief: run the fleet-upgrade-verification skill with --readiness once over every project in scope, treat its blockers and risks as the findings (a budget over a single replica, a pool past the skew ceiling and a webhook in the upgrade's path are critical; a budget over several replicas, a webhook refusing only what it matches today and a pool at the ceiling are major; a covering exclusion is minor; a readiness rule's blocker is critical, and its risk is minor for catalogue entries 9, 10, 11, 13 and 16 and major for every other entry), name objects where the queue would give ids, say "live brief, composed now; the weekly review has not run" in the headline, and close with the live form of the last line: there is no report file and no id to reply with until the Saturday review registers them.
  2. Read the queue, with the platform_control tools:
    • get_ranked_findings: the open backlog. Keep the rows whose check starts with upgrade-. A row in state queued or surfaced is undecided: nobody has decided on it, whether or not the hourly nudge has named it yet. accepted is decided (being worked on).
    • get_findings with state=snoozed, then state=dismissed: the other decided rows; the backlog never carries them. Keep the upgrade- rows of these too. Pass limit=1000 and project=<id> for each project in the summary's projects (the default page is 200 rows across every source); a page of exactly 1000 rows is cut, so say "at least" before that count.
  3. Compose the brief in exactly this shape, at most twenty-five lines, ids verbatim in backticks:

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.
