BloomDesktop: Skill for Claude Code

.claude/skills/nightly-triage/SKILL.md

nightly-triage is a skill for Claude Code from BloomBooks/BloomDesktop. It costs 115 tokens per session (1,807 once invoked), scanned C, original, MIT.

A procedure for reviewing failed nightly CI runs, where CI is automated code checking that runs on a schedule, and updating the project's failure record.

In plain words
What is it for?
It finds new failed nightly runs, checks their failed jobs and logs, identifies whether failures are known or new, and records their status.
Why use it?
It separates a quick record of what failed from deeper investigation, so the tracking document stays current without pretending to identify the root cause.

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 C, and why

nightly-triage scanned grade C with 1 finding 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.

The scan reads SKILL.md. This mod also ships 1 executable file (post-to-zulip.ps1), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

`rm -rf` from Git Bash.

How it starts

The opening of the file, as written. The whole thing — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Nightly triage

docs/nightly-failures/README.md is the high-level place where everyone can see which nightly failures have already been looked at and where each one stands. This skill brings it up to date. It is triage, not investigation: find out what failed and whether we already know about it, take a first look, and record that. Do not chase root causes, write fixes, or gather in-depth details here. That work belongs on a YouTrack card and/or a branch, and the doc just links to it.

1. Find the runs to look at

Read the doc's Last updated line. Every nightly run after that date is in scope:

gh run list --repo BloomBooks/BloomDesktop --workflow nightly.yml --limit 10 --json databaseId,createdAt,conclusion,headSha

If there are none, say so and stop.

2. For each failed run, name what failed

gh run view <id> --repo BloomBooks/BloomDesktop --json jobs        # failed jobs and steps
gh run view <id> --repo BloomBooks/BloomDesktop --log-failed       # the failing step's log

The log is large, so filter it:

  • The run's summary lines (* ✅ / * ❌) give each suite's counts.
  • Drop [WebServer] lines, which are noise from the component tests.
  • Playwright failures start at 1) <spec>:<line> › <title>. The 40 lines after that give the error and the source line.
  • C# failures show as Failed <TestName>.

Ignore errors from passing suites, such as AggregateError stacks in the vitest output.

3. Classify each failure against the doc

  • Seen again: the same test failing the same way as an existing entry. Add the date to that entry's Failed line. If its fix was supposed to cover this, say that it did not.
  • Known test, new symptom: an existing entry's test failing in a different way. Add a line to that entry. Make it a new entry only if the cause is clearly different.
  • New: not in the doc. Add a short entry: the date, the test and its assertion, and what a first look shows, labelled as a first look. Say plainly what is not yet known.
  • Fixed: an entry whose fix has landed, where the nightly has since passed on it. Remove the entry. Its history lives in git and on the card.

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.

Changes

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.

nightly-triage is a skill published in the GitHub repository BloomBooks/BloomDesktop (43 stars, last pushed today), licensed MIT. It adds 115 tokens to every session and 1,807 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-03.
