THE REGISTRY’S SCORE, AVERAGED PER PLAY
1,308 public Plays, read from their own files.
Each mark is a Play someone published. Its shape says what the Play reaches: a square is shell, a circle is an API, a half circle is a browser, a diamond is more than one. Orange means it writes. A hole through the middle means it runs steps in parallel.
889 of them arrived in the week of Aug 31.
Before that week, 26 Plays over 12 weeks, a few at a time. The Playoffs opened, and the catalog changed shape in seven days.
87% are a script wrapped as a procedure.
1,141 Plays reach the world through shell alone. 40 through an API alone, 85 through more than one kind of tool, 3 through a browser. 1,131 of 1,308 are read-only.
118 Plays call an API through an adapter. github leads.
GitHub v3 REST API 60, REST, 1,108 tools · Gmail API 10, REST, 79 tools · open-meteo 8, REST, 1 tools · Calendar API 7, REST, 37 tools. An adapter is a typed connection to a service, MCP or REST, with named credentials that stay on the machine. The rest of the catalog reaches the world through shell and browser.
Most are 4 steps. The deepest is 21.
85 Plays use more than one kind of tool, and those are where the depth is. 337 fan out, running up to 12 steps at once. The deepest today is aeo-ready by nishitbaria.
55 makers score 1.0 on everything they ship. sakshamsai26 leads.
The registry scores every Play from 0.35 to 1 on its rubric: declared effects, parameters, checks, provenance, and whether it runs anywhere. A maker gets the average across their Plays. How many and how often say how much; this says how well. sakshamsai26 1.00 · ankurrawat 1.00 · lgoyal6 1.00 · himanshu-jha 1.00 · bavya21 1.00.
89 Plays recorded what discovery cost.
The first run of a Play is the expensive one: the agent finds the path. Median 68,000 API tokens and 0.9 seconds of exploration, 12,976,703 tokens across all 89. The ones that record savings save about 18,568 tokens every run after.
They sort themselves into 6 ways of working.
Sorted by the words in their own files, tools, calls, and hosts, with nothing about time in the sorting. python3 65.7% · github 11.1% · bash 8.7%. The names are the tokens that best describe each group.
