"the two code points CPython refuses" counted classes: NUL is one code point, unpaired surrogates are the whole 2,048-wide D800-DFFF block. Say kinds, in both the docstring and the test comment that mirrors it, and restore the "odd" qualifier the test comment dropped -- an even trailing backslash run does not eat the closing quote. The soft-keyword test title still said "only special in statement position", which the previous commit's own three-way split contradicts for `case`: `case_block` is a clause head inside a `match` statement, not a statement. Add the case the subscript tool-name path lacked. A lone surrogate is reachable in a name through JSON.parse of MCP wire JSON, and that path has no UNPRINTABLE / LONE_SURROGATE fallback -- only the same ES2019 well-formed stringification the Literal path leans on.
core/ — product API spine
English | 中文
The session log, system-prompt assembly, tool registry, agent vocabulary, and concrete loop that form the harness's default control spine. These are product packages — the stable surface plugins and consumers build against.
| Package | Role | ctx key |
|---|---|---|
scope/ |
Scoped-context registration primitive | library — no ctx key |
session/ |
Event-sourced session log and in-memory store | ctx.sessions |
system-prompt/ |
Prompt and tool-schema assembly registry | ctx.systemPrompt |
tools/ |
Scoped tool registry and execution pipeline | ctx.tools |
agent/ |
Agent interface, registry, and event vocabulary | ctx.agents |
agent-loop/ |
Default concrete agent driver | ctx.agentLoop |
scope supplies the shared scoping primitive. agent owns the public seam, while agent-loop is its default implementation; extension plugins depend on the seam so the driver remains swappable.
Runnable compositions belong to examples/agent-spine-demo; this group owns only the swappable spine pieces.
