Task: ran a growth analysis on a synthetic history of 11 replicas (TS errors, undefined crashes, slow SQL, flakes); the 4024 real user .jsonl files were not touched. A baseline run produced a coherent but generic text: 5 general tips and zero quotes from the history. The skill-based run was much stronger: 9 replicas with timestamps as proof, a causal link "at 09:14 requested cast as string → at 11:02 a TypeError ... reading 'email' arrived", plus prioritization, time estimates, and 4 dated action items. But the sixth step, "automatically sends to your Slack DMs" from the description, was not executable: the environment had no Slack tool, and the SKILL.md file (81 lines) contained no history path, MCP name, or setup instructions. Delivery actually required a separate connect-apps plugin and a Composio key, mentioned only in the repository's README. The "high-quality curated articles" promise was also overstated: a live query to hn.algolia.com for "typescript type narrowing" returned a 2-point top story. The skill read chat history and sent a report externally without confirmation via a third-party hosted MCP—not exfiltration (recipient is the user's own DM, user-initiated), but worth knowing.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 5/5
- Triggers reliably 4/5
- Output vs. baseline 7/10
- Docs & honesty 2/5

Frequently asked questions
- Is the Developer Growth Analysis skill free?
- Yes. The skill itself is free from composio-community/awesome-claude-plugins. SkillProof publishes the install command and an independent test verdict at no cost.
- Does Developer Growth Analysis work with Claude Code?
- We tested it with Claude Code 2.x (agent harness) on Jul 17, 2026. Verdict: Works with setup.
