Removes OpenAI Responses "chain mode" from chatd. Closes CODAGT-445.
- Deletes `chatopenai/responses.go` (chain detection, activation, prompt filtering, response ID extraction) and its tests.
- Deletes the `ChainBroken` classification in `chaterror` and the chatloop retry bookkeeping that disabled chain mode mid-generation.
- Drops the `chain_broken` label from the `coderd_chatd_stream_retries_total` metric.
- Stops reading and writing `chat_messages.provider_response_id`
- Deletes the dead `ClearChatMessageProviderResponseIDsByChatID` query. Dropping the column is a follow-up migration.
- Deletes three chatloop hooks no caller sets (`ReloadMessages`, `DisableChainMode`, `PrepareMessages`), the dead `const AgentChatContextSentinelPath`, and stale chain-mode comments.

Metrics Documentation Generator
This tool generates the Prometheus metrics documentation at docs/admin/integrations/prometheus.md.
How It Works
The documentation is generated from two metrics files:
metrics(static, manually maintained)generated_metrics(auto-generated, do not edit)
These files are merged and used to produce the final documentation.
metrics (static)
Contains metrics that are not directly defined in the coder source code:
go_*: Go runtime metricsprocess_*: Process metrics from prometheus/client_golangpromhttp_*: Prometheus HTTP handler metricscoder_ai_gateway_*: AI Gateway metrics are registered through prefixed registerer that the scanner does not resolve.
Note
This file also contains edge cases where metric metadata cannot be accurately extracted by the scanner (e.g., labels determined by runtime logic). Static metrics take priority over generated metrics when both files contain the same metric name.
Edit this file to add metrics that should appear in the documentation but are not scanned from the coder codebase,
or to manually override metrics where the scanner generates incorrect metadata (e.g., missing runtime-determined labels like in agent_scripts_executed_total).
generated_metrics (auto-generated)
Contains metrics extracted from the coder source code by the AST scanner (scanner/scanner.go).
Do not edit this file directly. It is regenerated by running:
make scripts/metricsdocgen/generated_metrics
Updating Metrics Documentation
To regenerate the documentation after code changes:
make docs/admin/integrations/prometheus.md
This will:
- Run the scanner to update
generated_metrics - Merge
metricsandgenerated_metricsmetric files - Update the documentation file
