Pick a story: recorded sessions replay real probe-harness transcripts; commands tagged live-capable can re-run against the real endpoint from our edge, right now (▶ run live — the exact same request, live and recorded lines always labeled); sandboxed self-drive sessions are designed and gated (docs/TRY-IT.md).

Opportunities — the stories that would move this product's scores, from its own judged verdictsOpportunitiestop 8 of 37 stories with headroom
What would move Meltano’s scores — derived from its own judged verdicts, biggest headroom first. Each line quotes what the judge found missing; shipping it (or evidencing it publicly) is the fix.
Agenticness — how well agents can access and operate the productDrive the product through a documented public API
partialq3/10moves agent-readyimpact 31.5
Missing: a documented REST/OpenAPI or SDK-style public API, llms.txt or agent-facing API spec, independent confirmation of programmatic (non-CLI) control.
Ai pipelines — stories about ai pipelines in this arenaAI drafts a working connector from API documentation — auth, pagination, streams — that I review and ship
nonemoves PA Scoreimpact 30
Meltano documents building custom connectors via its SDK (meltano-docs-4, meltano-comm-8) and has a plugin/tap architecture, but there is no evidence of an AI-assisted or automated workflow that drafts a connector (auth, pagination, streams) directly from API documentation for human review — connector creation is manual/SDK-based, not AI-drafted.
Automation depth — how much of the product can run unattendedDefine rules that trigger actions automatically on events
nonemoves PA Scoreimpact 30
Meltano's evidence covers ELT pipelines, scheduling via Airflow, and plugin/connector management, but there is no mention of event-driven rule definitions or automatic action triggering based on arbitrary events - its orchestration is schedule-based, not event/rule-based automation.
Sync replication — stories about sync replication in this arenaI replicate databases with log-based CDC (binlog/WAL) so I capture updates and deletes without hammering the source
nonemoves PA Scoreimpact 30
Missing: any documentation or community evidence of log-based CDC support (e.g., tap-postgres WAL/logical replication, tap-mysql binlog reading), performance claims about reduced source load, or handling of deletes via CDC.
Schema evolution — stories about schema evolution in this arenaUpstream schema changes are detected and propagated by a policy I choose, instead of silently breaking loads
nonemoves PA Scoreimpact 30
The evidence covers catalog generation, stream/property selection, and incremental state tracking, but nothing explicitly addresses detecting upstream schema changes or applying a chosen policy (e.g., auto-add columns, fail-fast, quarantine) to prevent silent load breakage.
Agenticness — how well agents can access and operate the productPoint an agent at llms.txt or agent-oriented docs
nonemoves agent-readyimpact 30
A direct probe found no llms.txt (404) and no agent-oriented docs endpoint (openapi 404s), and no evidence pack item mentions agent-facing documentation formats; the only agent-relevant surface found is MeltanoHub's plugin API, which is a registry, not agent-oriented docs guidance.
Agenticness — how well agents can access and operate the productOperate the product with natural-language commands
nonemoves Built-in AIimpact 30
Meltano is CLI/YAML-driven (meltano init, meltano add, meltano config) with no evidence of a natural-language interface, chat command layer, or NL-to-CLI translation anywhere in the docs, community, or probes.
