1 Windows · PowerShell 7 · Command Code CLI.
2 Long session with heavy tool use — ~40 file writes/edits under ~/.agents/skills/blender-skill/**, ~25 PowerShell commands, several activate_skill calls.
3 Keep going until the request payload array grows past ~280 entries.
4 At some later request, the call is rejected with the 400 below. Observed 4 times out of many requests in one session — always at input[280], never another index.
5 Type continue → the retry succeeds immediately, with the prompt and all user-controllable input unchanged.
I could not isolate a single triggering action. The reproducible facts are: long/heavy session, and the offending entry is always at index 280.
Expected behavior
Every name sent in the request payload matches ^[a-zA-Z0-9_-]+$.
An invalid name is rejected at registration time (mod, MCP tool, or skill), naming the offending value and its source so it can be fixed locally — not surfaced later as an opaque 400.
If the payload is validated client-side before send, the error should echo the offending input[N].name value.
Actual behavior
The request is rejected:
400 Invalid 'input[280].name': string does not match pattern.
Expected a string that matches the pattern '^[a-zA-Z0-9_-]+$'.
The error does not reveal the offending value, nor which mod / MCP server / tool registered it.
The session then shows Error: Connection error. Type "continue" to try again. — i.e. it presents as a network problem, which misdirects debugging.
continue retries and succeeds unchanged, so work is not lost but is interrupted.
The index is always 280 across 4 failures and the message is byte-identical, which suggests one stable bad entry that only becomes reachable once the payload array is long enough — and likely explains the intermittency.
