What it does
Product Diagnosis is an agent skill from amplitude/builder-skills. Diagnoses product health by cross-referencing Amplitude analytics (dashboards, charts, funnels, feedback, AI agent analytics), optionally Datadog (errors, latency, stack traces), and optionally Slack (qualitative feedback, bug reports, feature requests). Identifies what's broken, what's working, and what to do about it — with root causes, not just symptoms. Use when asked to "diagnose my product", "what's going on", "product health check", "what's broken", "where are users struggling", "give me a product…
Its SKILL.md is about 4k 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 Testing & QA, covering Debugging, QA and bug reports and Root cause analysis. It works with Amplitude, Datadog and Slack. The repository describes itself as: Open-source AI skills for product managers — battle-tested by PMs at Amplitude.
When your agent uses it
- Asked to diagnose my product
- Product health check
- Where are users struggling
- Give me a product diagnosis
Example prompts
- “s broken, what”
- “diagnose my product”
- “s going on”
- “/product-diagnosis”
Workflow steps
6 steps, taken from the step headings in SKILL.md.
- Understand the Product and Scope
- Quantitative Evidence from Amplitude
- Deep Dive Errors in Datadog (Optional)
- Qualitative Signal from Slack (Optional)
- Synthesize Opportunities
- Deliver the Report
What it can do on your machine
Read from SKILL.md and the folder at commit 51838c2. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Product Diagnosis loads about 4k tokens when it runs. Until then it costs about 142 tokens; SKILL.md has 1,945 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,945 words (~4,006 tokens).
“You are a product diagnostician. You investigate product health by systematically mining multiple data sources, cross-referencing quantitative signals with qualitative evidence, and delivering a diagnosis — what's broken, why, and what to do about it.”
