Phase 7 verify finding from TC #26 against :model cloud:
HTTP 400 from openrouter→Amazon Bedrock:
"tools.0.custom.name: String should match pattern
'^[a-zA-Z0-9_-]{1,128}$'"
Anthropic via Bedrock validates tool names against that regex and
rejects dots. PHASE2 originally chose "." as the namespace separator
("boltzmann.list_dir"); OpenAI tolerated it, Bedrock does not.
Separator switched to "__" (two underscores) everywhere — internal
API matches on-wire shape, no transformation layer:
- repl.lua:
- tools_schema builds "alias__name"
- dispatch_tool_call splits via "^(.-)__(.+)$" (non-greedy → leftmost __)
- :mcp tool parser uses same split
- :mcp tools formatter prints "alias__name"
- HELP block shows <alias__name>
- safety.lua confirm_tool_call: alias.* glob → alias__* glob
- config.lua example block: keys rewritten
- docs/PHASE2.md: amendment header added; §1, §2 row, §3 config.lua
row, §5 wire-shape JSON examples, §6 auto_approve schema, §7
meta-cmd table, §12 plan all updated. Original "." references
preserved in commit history.
Constraint: aliases must not themselves contain "__" so the parse
stays unambiguous. Tool names from MCP servers may have underscores
freely.
Second fix bundled — uninformative broker error:
Previously "broker error: transport: HTTP response code said error"
Now "broker error: transport: HTTP 400: {full body snippet}"
ffi/curl.lua M.post_sse changes:
- FAILONERROR no longer set (was hiding the response body).
- raw_body accumulator added alongside the SSE buffer; captures
every byte regardless of SSE shape.
- After perform, check status_code via curl_easy_getinfo. On >=400,
return (nil, "HTTP <code>: <body[:400]>"). 2xx unchanged.
- End-of-stream SSE flush only runs on 2xx (no false event on
error bodies that aren't SSE-shaped).
- Phase 1 callers reading just first return slot stay correct.
End-to-end verified:
- :model cloud + tools=[boltzmann__read_file ...] +
"Use boltzmann__read_file with path=/etc/hostname" →
Claude emits tool_call with name="boltzmann__read_file",
args='{"path": "/etc/hostname"}'. ok=true, transport clean.
- Force-bad tool name "bad.name.with.dots" → err string carries
the full bedrock 400 with the regex-pattern message visible.
TC #26 (sub-loop end-to-end) is now testable against cloud — the
error that blocked it is resolved.
