feat(opencode): CAS run insights and Synapse request processing probe - #11
Conversation
Add fork-local observability so OpenCode can show how CAS and Synapse process agent requests: pipeline health, list/insights/trace for runs, and synapse_probe for x-synapse-served-model plus rate limits. Docs pack INDEX + insights status; AGENTS.md points at AIO KB-AI-036. Tests: cas-bridge-routing 20 pass (formatters + routing injection).

Inline comments:
In @.opencode/command/cas-insights.md:
- Line 22: Update the security rule near the token-spend reporting guidance to
prohibit printing access tokens or credentials, rather than “tokens” generally,
so token-spend metrics remain permitted.
In @.opencode/tool/cas-bridge-lib.ts:
- Around line 701-705: Update formatRunList to sort runs by createdAt in
descending order before generating the “newest first” output, ensuring the
displayed order matches the header regardless of CAS payload ordering.
- Around line 355-361: Define shared CAS and health-check timeout constants in
cas-bridge-lib.ts, then add AbortSignal.timeout(...) to every outbound request:
callCasRest at .opencode/tool/cas-bridge-lib.ts:355-361 using CAS_TIMEOUT_MS,
fetchCasHealth at .opencode/tool/cas-bridge-lib.ts:406 using the shorter
health-check timeout, fetchSynapseHealth at .opencode/tool/cas-bridge-lib.ts:420
using the same health-check timeout, and probeSynapseChat at
.opencode/tool/cas-bridge-lib.ts:522-544 using the appropriate shared timeout so
its latency measurement remains bounded.
- Around line 733-739: Update the payload normalization logic around the
CasRunRow extraction to process nested run and data envelopes before applying
the bare-object heuristic. Only treat the top-level object as a CasRunRow when
o.id is a string; remove o.status from that fallback so payloads with status
plus data reach the nested data.run or data.id handling.
- Around line 370-379: Update the error-detail construction in the CAS REST
response handling to retain the raw 400-character body when parsed JSON provides
no error.code, error.message, or correlation_id. Preserve the existing
structured detail when any known field is present, and ensure the thrown error
from this block never ends with an empty detail.
- Line 690: Cap the run.error value in the error bullet before interpolating it,
using the existing response-length limit or truncation convention used by the
surrounding run-insights formatting. Preserve the current bullet text and omit
the field only when run.error is absent.
- Around line 519-520: Update the maxTokens handling near the existing maxTokens
clamp to reject non-finite numeric inputs before applying Math.max and Math.min,
while preserving the current 1–64 bounds and default for absent values. Ensure
NaN and infinities cannot reach the request payload as an invalid or uncapped
token value.
In @.opencode/tool/cas-safe-list-runs.ts:
- Around line 45-47: Update the parsed-run branch in the CAS list-runs handler
to apply redactSecrets to the output of formatRunList and then wrap the redacted
result with wrapUntrusted before returning it. Keep the existing fallback
wrapping for unparsed results unchanged.
In @.opencode/tool/cas-safe-run-insights.ts:
- Around line 26-29: Update the run-handling flow around parseCasRunPayload and
formatRunInsights so the formatted run summary is passed through
wrapUntrusted("cas_get_run", ...) before returning, matching the existing raw
fallback. Preserve the current includeRaw behavior and the environment-gated,
offline-queue, and system-prompt behavior under .opencode/.
In `@AGENTS.md`:
- Line 171: Update the CAS bridge tool list in the AGENTS.md documentation to
use the registered underscore identifiers, including cas_auth_status,
cas_safe_list_runs, cas_pipeline_status, and synapse_probe. Retain hyphenated
names only where they refer to façade agents or file paths, such as
cas-delegate, cas-drafter, and cas-matter-audit.
In `@docs/implementation/current/FEAT-CAS-OPENCODE-BRIDGE/insights.md`:
- Around line 3-5: Update the Scope statement in insights.md to distinguish the
runtime implementation as fork-local .opencode/ while also including the
supporting documentation and package test changes listed in the document,
including cas-bridge-routing.test.ts.
- Around line 3-5: Update the date and validation claims in the insights
document, including the sections around the document metadata and the referenced
validation results, to use the actual execution date. If those checks have not
run, relabel the August 2, 2026 evidence as planned rather than completed, while
preserving accurate validation details.
In `@packages/opencode/test/plugin/cas-bridge/cas-bridge-routing.test.ts`:
- Around line 304-317: Update the test around synapseKeySource to snapshot
SYNAPSE_API_KEY, GPAAS_API_KEY, and SYNAPSE_MCP_BEARER_TOKEN before
modification, then restore each original value in a finally block or afterEach
cleanup so restoration occurs even when assertions fail.

Keep the raw body when the JSON error has no known fields.
If the body parses as JSON but contains no error.code, error.message, or correlation_id, detail becomes an empty string. The thrown message then reads CAS REST 500: . Fall back to the raw slice, as probeSynapseChat already does at Line 550.

Cap the run error string.
Every other free-text field here is sliced: title to 100 characters, the trace preview to 60. run.error is printed in full. cas-safe-run-insights.ts applies no MAX_RESPONSE_CHARS truncation, unlike cas-safe-run-trace.ts. A long CAS stack trace therefore floods the agent context.

Redact and label parsed run output.
Line 46 formats remote run fields directly. formatRunList includes the run title without redaction. A CAS run title that reflects a bearer token or instruction-like text reaches the model without redactSecrets or wrapUntrusted.
Apply both protections before returning parsed runs.

Fence the formatted run output as untrusted.
Line 29 wraps the raw fallback with wrapUntrusted. Line 28 returns the formatted summary without it. The formatted summary still embeds CAS-controlled text, including title, error, and templateId.
