D2b, order 20260821T041145Z-8516817669-from-.claude. Measured by .claude
against the org: llms.txt was missing in 23 of 23 org repos (probe verified
both ways in the same call chain: README.md -> 200, a nonexistent path -> 404).
The operator decision of 21.08 creates it in 6 repos -- the catalog plus the 5
artifacts with their own run path -- and deliberately not in the 12 plugin
repos, whose entry surface is already uniform.
The reader is an AI agent already standing in this repository that needs one
deterministic place to find what this artifact is and how it is started. Not
crawlers: measurements show the major agent crawlers skip /llms.txt and read
the HTML directly, so that would not be a reason that holds.
Follows the llmstxt.org convention: H1, one blockquote summary, then H2
sections holding lists of markdown links, with "Optional" naming the links an
agent may skip. Deliberately minimal -- llms.txt is a convention, not a
ratified standard, and a W3C proposal from June 2026 diverges from the
Answer.AI spec, so a format change should stay cheap.
The install block is quoted byte-identical from README.md's first code block
(verified with diff against README.md:67-68), not rewritten. A rewritten
variant would be a second source of truth, not an entry point.
Docs only; the Iron Law does not fire. Full suite unchanged vs HEAD:
2253 tests / 2247 pass / fail 0, exit 1 from the known jetbrains-parser
after()-hook assertion, measured identically on a stashed HEAD tree.
