What it does
Analyze GitHub Flake is an agent skill from flutter/flutter. Expertise in analyzing flake github issues in the flutter/flutter repository. Use when a user wants to analyze the flakiness of a specific link to a flutter github issue.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Mobile, covering Cross-platform mobile apps and Failing and flaky tests. It works with GitHub, Flutter and Dart. The repository describes itself as: Flutter makes it easy and fast to build beautiful apps for mobile and beyond. The licence is BSD-3-Clause.
When your agent uses it
- A user wants to analyze the flakiness of a specific link to a flutter github issue
- Tasks that involve Cross-platform mobile apps
- Tasks that involve Failing and flaky tests
Example prompts
- “/analyze-github-flake”
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Is filed by fluttergithubbot
- Has a title of the format " is X% flaky"
What it can do on your machine
Read from SKILL.md and the folder at commit 9911f49. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
ghcurl
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
ci.chromium.orgcr-buildbucket.appspot.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Analyze GitHub Flake loads about 1.1k tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 414 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

-->Flake analysis instructions
Rules You should not modify ANY files - you are only to provide an analysis of why the specific check is flaking. You should only look at the issue body, as well as comments containing links to additional builds. You should not attempt to solve the flakes or pinpoint root causes inside of flutter/, just provide a high level summary of what is going on and bucket the failures into distinct types.
Collecting the list of failing builds and obtaining the logs
Github issue urls take the form of https://github.com/flutter/flutter/issues/<issue-number>. Where issue-number is a number.
Get information about the issue by using gh issue view <issue-number> --repo flutter/flutter --json=author,body,id,labels,number,state,title,url
For example to find information about the issue https://github.com/flutter/flutter/issues/174116 you can call gh issue view 174116 --repo flutter/flutter --json=author,body,id,labels,number,state,title,url
At this point there are two possible cases. If the issue
- Is filed by fluttergithubbot
- Has a title of the format "<ci.yaml target> is X% flaky" Then it is of the type we are looking to analyze. If it is not, you should short circuit here, either notifying the user that the issue is not filed by the github flake bot (if they directly asked for the skill to be invoked) or otherwise continue with your previous work (if they did not).
If the previous conditions are met, the title will contain the name of the flaking check, and the body will contain urls which link to instances where the check failed or flaked, each on a new line, directly after "Flaky builds:". You should also inspect the comments and find each comment made by "login": "fluttergithubbot", and extract the urls from there as well (the format will be the same, with an example flake at the top, and the full list immediately after the "Flaky builds:" header).
Show full SKILL.md (114 more words)Show less
To find information about the specific failure take one of the urls listed in the issue body.
That link takes the format "https://ci.chromium.org/ui/p/flutter/builders/<bucket>/<check_name>/<buildNumber>/overview",
Example https://ci.chromium.org/ui/p/flutter/builders/prod/Windows%20plugin_test/16247/overview where prod is the <bucket>, Windows%20plugin_test is the <check_name> and 16247 is the <buildNumber>.
Then use the <buildNumber> to get the test logs metadata by running the following command.
curl 'https://cr-buildbucket.appspot.com/prpc/buildbucket.v2.Builds/GetBuild' \
-H 'accept: application/json' \
-H 'accept-language: en-US,en;q=0.9,es;q=0.8' \

-H 'sec-ch-ua: "Chromium";v="146", "Not-A.Brand";v="24", "Google Chrome";v="146"' \

-H 'sec-fetch-site: cross-site' \
-H 'user-agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/146.0.0.0 Safari/537.36' \
-H 'x-return-encrypted-headers: all' \
--data-raw '{"builder":{"project":"flutter","bucket":"<bucket>","builder":"<check_name>"},"buildNumber":<buildNumber>,"mask":{"fields":"id,builder,builderInfo,number,canceledBy,createdBy,createTime,startTime,endTime,cancelTime,status,statusDetails,summaryMarkdown,output,steps,tags,schedulingTimeout,executionTimeout,gracePeriod,ancestorIds,retriable"}}'Ignore the characters )]}' that start the response and treat the rest like json.
Inspect the content of the logs to determine the cause of the failure.
Do this for each of the urls in the issue body. Collect the logs for each of the specific failures, and categorize them by the type of failure in to a high level summary.
