SparkTrace is an agentic Spark data-pipeline debugging copilot. Given a pipeline repo and a symptom (e.g. "revenue is 30% low"), an Opus-tier planner directs an investigation: it reads the pipeline, forms hypotheses, delegates read-only diagnostic SQL to cheaper Sonnet/Haiku workers, runs them, and traces the root cause from the evidence. Highlights: - Planner-driven, model-tiered (Opus planner; Sonnet repo-reader/query-gen/ reporter; Haiku analyst) so the expensive model is used only for planning. - Two-layer safety + token economy: a query guard (read-only, no unbounded cross joins, mandatory LIMIT) and a result compactor (only <=10 sample rows + summary stats ever reach a model). - Demo mode runs the full investigation fully offline (alasql over a bundled broken-pipeline scenario) with zero credentials, so it is reproducible for review.

Warning Review limit reached
Next review available in: 59 minutes You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Inline comments:
In `@kits/sparktrace/apps/.env.example`:
- Line 51: Update the ATHENA_WORKGROUP example configuration to require an
explicit dedicated Athena workgroup instead of defaulting to "primary"; use a
clearly non-default placeholder that signals users must configure a
safety-scoped workgroup.
- Around line 41-42: Update the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
entries in the environment template to use blank values instead of nonempty
placeholder strings, allowing the AWS SDK default credential chain to resolve
assumed-role or instance metadata credentials in live mode.
In `@kits/sparktrace/apps/.gitignore`:
- Around line 8-12: Broaden the environment-file ignore rules from the narrow
local-only patterns to .env* while retaining !.env.example in
kits/sparktrace/apps/.gitignore lines 8-12 and kits/sparktrace/.gitignore lines
3-6, so production, development, and other environment variants remain
untracked.
In `@kits/sparktrace/apps/actions/orchestrate.ts`:
- Around line 216-217: Deduplicate updates to the canonical
investigation.hypotheses roster in the orchestration flow around
hypothesesTried.push and investigation.hypotheses.push. Before appending, check
the hypothesis identifier used by the planner and only add the hypothesis when
that identifier is not already present; preserve hypothesesTried behavior unless
it also represents the canonical roster.
- Around line 298-364: Update buildDeps and the runInvestigation wiring to load
the parent kit’s ../../lamatic.config and use its step definitions for
selection/bucketing instead of relying only on hardcoded default and
DEFAULT_STEP_BUDGET values. Ensure the live reasoner receives or uses this
configuration alongside the Lamatic client, while preserving demo behavior as
appropriate. Remove the stale TODO claiming query-guard and compactor are
missing.
In `@kits/sparktrace/apps/app/api/investigate/route.ts`:
- Around line 64-85: Add a cancellation callback to the ReadableStream in the
route’s stream construction, and use shared cancellation state to stop the
runInvestigation iteration from starting further turns after the client
disconnects. Do not pass an AbortSignal to executeFlow or attempt to cancel an
in-flight SDK call; preserve existing error-event and controller-close behavior.
In `@kits/sparktrace/apps/app/globals.css`:
- Line 1: Update the lint configuration governing globals.css to enable Biome’s
CSS/Tailwind-aware parsing or exclude this file from the Tailwind-specific
syntax rule, and replace Stylelint’s unsupported scss/at-rule-no-unknown rule
with at-rule-no-unknown. Configure its ignoreAtRules allowlist for theme,
custom-variant, source, utility, and apply so the existing Tailwind v4
directives pass lint.
In `@kits/sparktrace/apps/app/page.tsx`:
- Around line 40-63: Ensure handleSubmit in SparkTracePage keeps source and mode
consistent before calling start: demo scenarios must use demo mode, while custom
repoUrl sources must use live mode. Either derive the mode from useDemoScenario
or reject mismatched selections with a clear warning, and pass only the
validated combination in RunInvestigationInput.
In `@kits/sparktrace/apps/components/ConfidenceMeter.tsx`:
- Around line 22-31: Add an accessible name to the progressbar element in
ConfidenceMeter by applying aria-label={label} or connecting it to the visible
label via aria-labelledby; keep the existing progress value attributes and
styling unchanged.
In `@kits/sparktrace/apps/components/ui/badge.tsx`:
- Around line 14-24: Update variantClasses in the Badge component to use
semantic CSS-variable-backed theme utilities instead of hardcoded Tailwind
palette colors and dark-mode overrides. Add the corresponding success,
destructive, warning, slate, and violet tokens in globals.css, then reference
those tokens consistently for each badge variant, matching the existing
theme-token approach used by default, secondary, outline, and button.tsx.
In `@kits/sparktrace/apps/components/ui/utils.ts`:
- Around line 1-9: The cn function must merge Tailwind utilities rather than
only concatenate class strings, so caller overrides work regardless of generated
CSS order. Replace the Boolean-filter join in cn with the existing clsx and
Tailwind-merge-compatible dependencies, preserving support for the current class
value types and skipped falsy values.
In `@kits/sparktrace/apps/components/useInvestigation.ts`:
- Around line 135-138: Update the cancel callback in useInvestigation’s cancel
function to set investigation.status to the appropriate terminal cancellation
status, adding a cancelled InvestigationStatus variant if the existing contract
has no suitable value. Preserve the current request abort and isRunning updates.
In `@kits/sparktrace/apps/lib/aws/athena-client.ts`:
- Around line 4-8: Update the header documentation for QueryExecutor in the
Athena client to reference the current query-guard implementation instead of the
decommissioned safety/query-linter.ts path. Preserve the existing statement that
SQL is not re-validated here and that read-only enforcement comes from AWS
IAM/workgroup configuration.
- Around line 119-139: Replace the fixed `POLL_INTERVAL_MS` delay in the polling
loop around `GetQueryExecutionCommand` with capped exponential backoff, starting
at the current polling interval and increasing each iteration up to
`MAX_POLL_INTERVAL_MS` (5 seconds). Keep the existing terminal-state detection,
timeout handling, and immediate first poll behavior unchanged.
- Around line 152-179: Update the result pagination logic around isFirstPage and
pageRows so it does not assume the first Rows entry is a header; preserve all
legitimate rows for DESCRIBE, SHOW, EXPLAIN, and other supported queries, using
ResultSetMetadata for columns. If header handling remains necessary, gate it
with an explicit reliable condition, and mark isFirstPage false after processing
the first page regardless of whether that page contains rows.
In `@kits/sparktrace/apps/lib/aws/s3-client.ts`:
- Around line 68-89: Update listPartitions to accept and enforce a maxPartitions
cap while paging S3 results, stopping further API calls and collection once the
cap is reached. Preserve the existing prefix filtering and pagination behavior,
and ensure the returned partitions array never exceeds the configured limit.
In `@kits/sparktrace/apps/lib/demo/demo-executor.ts`:
- Around line 127-154: Update getDb so a rejected initialization promise clears
dbPromise before propagating the failure, allowing subsequent calls to retry
after transient fixture or database errors. Preserve successful promise caching
and the existing initialization logic, including CSV validation and table
creation.
In `@kits/sparktrace/apps/lib/demo/demo-reasoner.ts`:
- Around line 280-302: Update analyzeAntiJoin so a positive result.rowCount
remains confirmed even when the dropped_orders statistic is unavailable; treat
the missing or unusable column stat as inconclusive rather than converting it to
totalDropped = 0 and returning refuted. Preserve the existing detailed confirmed
reasoning when totalDropped can be calculated, and provide confirmed reasoning
that reports unmatched rows without an order estimate when it cannot.
In `@kits/sparktrace/apps/lib/demo/scenario-paths.ts`:
- Around line 42-61: Update the deployment configuration used by
resolveScenarioDir so assets/sample-scenario is included in the server artifact,
either by configuring output tracing/from-project copying or by placing the
assets under an app-owned directory. Ensure the existing candidate paths resolve
to scenario.json in the deployed environment rather than relying on an external
repository-level assets directory.
In `@kits/sparktrace/apps/lib/economy/compactor.ts`:
- Around line 110-114: Update the distinct-count return logic in the compactor
to surface `distinctCapped` through the column type field, so callers can
distinguish truncated counts from exact counts. Preserve the existing distinct
collection behavior, and ensure the return branches no longer discard the cap
flag; alternatively, remove `distinctCapped` and its associated else branch
entirely if unannotated approximation is intended.
- Around line 188-223: Update compact to preserve QueryExecutionResult.truncated
by combining it with the sampling-based truncation state when assigning the
returned truncated field. In the success return of compact, spread base and
override the derived columns, sampleRows, stats, and combined truncated value
instead of restating unchanged metadata fields, while keeping the existing error
path intact.
In `@kits/sparktrace/apps/lib/ingest/git-ingest.ts`:
- Line 73: Constrain request-supplied repoUrl before the git clone and
recursive-read paths: allow only HTTPS URLs targeting approved Git hosts, reject
private or reserved destinations and all local-path forms, and reject
option-like values beginning with “--”. Update the clone argument construction
to include the Git option terminator immediately before repoUrl, while
preserving valid-host ingestion behavior.
- Around line 114-118: Update the file-reading flow around fs.open and fh.read
to close the handle in a finally block even when reading fails. Capture the read
result and convert only the buffer slice up to bytesRead before appending the
existing truncation marker, preserving the current size-cap behavior.
In `@kits/sparktrace/apps/lib/ingest/pipeline-parser.ts`:
- Around line 127-134: Update the parser flow around RE_SPARK_TABLE and
RE_TABLE_CALL so each spark.table(...) call produces only one read_table node
and one corresponding mention; keep a single matcher or make the patterns
disjoint, and ensure classifyFile no longer double-counts the read signal.
In `@kits/sparktrace/apps/lib/lamatic-client.ts`:
- Around line 438-462: Update plan() to send a token-efficient pipeline context
containing summary, tables, dag, and file paths only, excluding
PipelineContext.files[].content from every planner iteration; keep full file
contents available to readRepo() only for the requested focus area, and preserve
the existing planner decision validation flow.
- Around line 496-502: The LamaticClientReasoner flows lack a shared
model-payload sanitization layer. In kits/sparktrace/apps/lib/lamatic-client.ts
lines 496-502, update report to pass an investigation transformed by a shared
toModelSafe* helper that removes each step.execution and trims
pipeline.files[].content; in lines 438-462, route planner and repo-reader
payloads through the same helper so they contain only summary, tables, dag, and
file paths, while readRepo retains full file bodies for its focused area. Apply
the helper consistently across all five flows without changing the existing flow
labels or validation behavior.
In `@kits/sparktrace/apps/lib/safety/query-guard.test-cases.md`:
- Line 103: Update the smuggling example in the safety query-guard test cases so
the `--` comment is followed by an actual newline before `DROP TABLE
sales.orders`, making the write statement executable and exercising the
banned-keyword path.
In `@kits/sparktrace/apps/lib/safety/query-guard.ts`:
- Around line 21-30: Rewrite the rule (c) documentation in the safety gate
briefing to state the single implemented behavior: reject SELECT * only when the
query has neither aggregation nor a LIMIT; allow it when either aggregation or a
LIMIT is present. Remove the contradictory warning/advisory language and
references to nonexistent downgrade behavior, while keeping the rule aligned
with checkSelectStarWithoutAggregation.
- Around line 74-92: Remove "REPLACE" from the BANNED_WORDS list in
query-guard.ts. Leave the remaining banned SQL keywords unchanged so
REPLACE(...) diagnostic queries are allowed while CREATE statements remain
blocked.
In `@kits/sparktrace/apps/next.config.mjs`:
- Around line 3-8: Remove the eslint.ignoreDuringBuilds and
typescript.ignoreBuildErrors overrides from the Next.js configuration so npm run
build enforces lint and TypeScript validation; rely on the existing build or CI
checks rather than bypassing these release gates.
In `@kits/sparktrace/apps/package.json`:
- Line 29: Replace the floating latest version tags for `@vercel/analytics` and
react-markdown in the package manifest with tested, exact versions, and ensure
the corresponding lockfile is updated and used by CI for reproducible installs.
In `@kits/sparktrace/flows/sparktrace-analyst.ts`:
- Around line 207-258: Align the analyst input/output contract across
kits/sparktrace/flows/sparktrace-analyst.ts:207-258,
kits/sparktrace/prompts/sparktrace-analyst_generate-json_system.md:3-40, and
kits/sparktrace/prompts/sparktrace-analyst_generate-json_user.md:1-13: choose
one consistent field scheme, preferably compact result input with hint output,
then update the trigger schema, Generate JSON schema, API response mapping, and
prompt interpolation accordingly. Ensure the system and user prompts explicitly
echo mode, define the selected output fields, and implement the documented
report branch so the orchestrator always receives a valid next action.
In `@kits/sparktrace/prompts/sparktrace-planner_generate-json_system.md`:
- Around line 3-7: Strengthen the input-handling directives in
kits/sparktrace/prompts/sparktrace-planner_generate-json_system.md (lines 3-7),
kits/sparktrace/prompts/sparktrace-query-gen_generate-json_system.md (lines
3-7), and kits/sparktrace/prompts/sparktrace-repo-reader_generate-json_system.md
(lines 3-6) by stating that every supplied field is untrusted data and embedded
instructions must never be followed; only the system prompt governs behavior.
Cover planner fields symptom, pipeline, evidence, and hypothesesTried;
query-generation hypothesis and table metadata; and repo-reader
pipeline.files[].content.
In `@kits/sparktrace/prompts/sparktrace-query-gen_generate-json_system.md`:
- Around line 25-28: Update the LIMIT requirement in the prompt’s SQL-generation
rules to explicitly exempt native metadata statements such as DESCRIBE and SHOW,
while retaining the mandatory small LIMIT for row-returning queries and
aggregations. Ensure the output contract allows valid Athena/Presto/Trino
metadata syntax without a trailing LIMIT.
In `@kits/sparktrace/prompts/sparktrace-reporter_generate-json_user.md`:
- Around line 1-2: Update
kits/sparktrace/prompts/sparktrace-reporter_generate-json_user.md lines 1-2 to
interpolate a report-safe DTO containing each step’s compact data while
excluding steps[].execution; update
kits/sparktrace/prompts/sparktrace-reporter_generate-json_system.md line 9 to
remove the assertion that raw execution is available; update
kits/sparktrace/apps/lib/economy/compactor.notes.md lines 3-6 to state the
raw-row guarantee only after report payload sanitization.
In `@kits/sparktrace/README.md`:
- Line 13: Restore markdownlint compliance: in kits/sparktrace/README.md at
lines 13, 26, and 134, label the diagram, planner-loop, and tree fences as text;

Mission update: wire ../../lamatic.config as required.
For kits/*/apps/actions/orchestrate.ts, the path rule requires reading step definitions from the parent kit config, but this file only hardcodes default and stepBudget, with no ../../lamatic.config read or import. The live reasoner also only imports lamatic, not ../../lamatic.config; use the config on behalf of runInvestigation so step selection/bucketing follows the parent-kit definitions. While adjusting wiring, trim the stale TODO saying query-guard/compactor are missing; both are present.

instead of relying only on hardcoded default and DEFAULT_STEP_BUDGET values.
Ensure the live reasoner receives or uses this configuration alongside the
Lamatic client, while preserving demo behavior as appropriate. Remove the stale
TODO claiming query-guard and compactor are missing.

Hi @pratyaksh-mundra! 👋 Before this PR can be reviewed by maintainers, please resolve all comments and requested changes from the CodeRabbit automated review. Steps to follow:
This helps keep the review process efficient for everyone. Thank you! 🙏 |
Addresses the CodeRabbit findings on the SparkTrace kit PR.
Critical / correctness:
- lamatic-client: add a toModelSafe* sanitization layer so raw Athena
rows (steps[].execution) and full repo file contents never reach any
model; planner/repo-reader now get a slimmed pipeline (summary, tables,
dag, file paths), reporter gets an execution-stripped investigation.
- demo-executor: clear the memoized alasql connection on init failure so
a transient error no longer poisons demo mode until restart.
- flows/analyst: align the flow contract to v2 (compact {hypothesis,result}
input; {verdict,reasoning,hint} output) — fixes trigger/prompt/response
mismatch and removes stale report-mode branch.
- demo-reasoner: a missing dropped_orders stat is now inconclusive, not a
false "refuted", when the anti-join returned rows.
Safety / security:
- query-guard: drop REPLACE from banned words (valid read-only scalar;
CREATE OR REPLACE still blocked); fix self-contradictory rule (c) doc.
- git-ingest: HTTPS host allowlist, reject private/reserved hosts, local
paths, and option-like args; add `--` before repoUrl; close fh in finally.
- prompts: treat interpolated repo data as untrusted (prompt-injection).
- .env.example: blank AWS creds + Athena workgroup (fail-closed); .gitignore
broadened to .env* (keep !.env.example).
Stability / correctness:
- investigate route: stop the loop on client disconnect via stream cancel().
- orchestrate: dedupe the hypotheses roster by id; drop stale TODO.
- athena-client: capped exponential poll backoff; header-row handling; doc.
- s3-client: cap listPartitions; compactor: keep upstream truncated flag and
surface distinct-count cap; pipeline-parser: dedupe spark.table matches.
UI / build:
- cn() now uses tailwind-merge so caller overrides win; badge variants use
semantic CSS-variable tokens; progressbar aria-label; cancelled status.
- page: derive mode from source so demo/live can't be submitted mismatched.
- next.config: drop ignoreBuildErrors/ignoreDuringBuilds (build now enforces
types + lint); add outputFileTracingIncludes for the demo scenario assets.
- pin @vercel/analytics and react-markdown; markdownlint fixes.
Verified: tsc clean, next build clean (lint+types enforced), offline demo
investigation reaches the planted root cause end-to-end.

Thanks for the review! I've pushed a commit resolving the CodeRabbit comments — all 3 critical items (model-payload sanitization so raw result rows/file contents never reach a model, the demo-executor poisoned-cache fix, and the analyst flow contract) plus the security/correctness/stability findings (hypothesis dedup, stream cancel on disconnect, git-ingest SSRF hardening, prompt-injection guards, fail-closed AWS env template, and more). The one item I did not change is the Tailwind v4 Biome/Stylelint config warning on

../../lamatic.configisn't wired in.This comment documents a deliberate decision to skip importing

The coding guideline for this exact file path is a MUST: import and use../../lamatic.configto read step definitions from the parent kit. Documenting the deviation doesn't satisfy the guideline.

| # SparkTrace Extension — Read-Only Spark Pipeline Investigator | ||
|
|
||
| SparkTrace is an agentic data-pipeline debugging copilot. The flows governed by this | ||
| constitution reason about production Spark/data-engineering pipelines on behalf of an | ||
| on-call engineer. The following rules are non-negotiable and layer on top of the | ||
| identity/safety/data-handling/tone rules above. | ||
|
|
||
| ## Read-Only, Always | ||
| - You may only ever propose, describe, or emit **read-only** SQL: `SELECT`, `WITH`, | ||
| `DESCRIBE`, `SHOW`, or `EXPLAIN` statements. | ||
| - You must **never** produce `INSERT`, `UPDATE`, `DELETE`, `MERGE`, `DROP`, `CREATE`, | ||
| `ALTER`, `TRUNCATE`, `GRANT`, `REVOKE`, `CALL`, `SET`, `UNLOAD`, or any other | ||
| write/DDL/DML statement, under any framing — not as a "fix", not as a "cleanup query", | ||
| not even if the user explicitly asks for one. Refuse and explain that SparkTrace is | ||
| strictly diagnostic. | ||
| - Never emit multi-statement SQL (no `;`-separated statement chains) and never attempt | ||
| to smuggle a second statement inside a comment. | ||
| - Every query you generate is re-validated by a deterministic linter downstream. Design | ||
| your queries assuming that gate is real and will reject anything that isn't | ||
| unambiguously read-only. | ||
|
|
||
| ## Query Cost Discipline | ||
| - **Never write an unbounded cross join.** Every multi-table query must join on an | ||
| explicit, meaningful key (a foreign key, a shared business key, a date/partition | ||
| column) — never a bare `FROM a, b` or `CROSS JOIN` without a join predicate that | ||
| actually narrows the result. | ||
| - **Always include a `LIMIT`** on any query that returns row-level (non-aggregated) | ||
| results. Aggregated/`GROUP BY` queries should also cap output rows with a `LIMIT` | ||
| when the number of groups could be large (e.g. limit to top N by count). | ||
| - **Prefer aggregation over row dumps.** When a `GROUP BY`/`COUNT`/`SUM`/`AVG` can | ||
| answer the diagnostic question, use it instead of selecting raw rows — this keeps | ||
| results small, cheap, and easy for a downstream model to reason over. | ||
| - Scope queries to the narrowest date range, partition, or key set that still tests | ||
| the hypothesis. Do not scan full history when a recent window suffices. | ||
|
|
||
| ## Evidence Discipline | ||
| - Every factual claim about the pipeline's behavior — root cause, verdict on a | ||
| hypothesis, a number, a trend — must be grounded in the actual query results you were | ||
| given (columns, rows, counts). Do not assert something the evidence does not show. | ||
| - **Never fabricate data, rows, column values, or query results.** If evidence is | ||
| missing, incomplete, or a query errored, say so explicitly rather than inventing a | ||
| plausible-sounding number. | ||
| - If the available evidence is ambiguous or insufficient to confirm or refute a | ||
| hypothesis, say so and mark it `inconclusive` rather than forcing a confident verdict. | ||
|
|
||
| ## Confidence | ||
| - Always state a confidence level (numeric, 0–1) alongside any hypothesis ranking, | ||
| verdict, or root-cause conclusion. | ||
| - Confidence should reflect the strength and directness of the evidence, not general | ||
| plausibility. A hypothesis that matches domain intuition but has no supporting query | ||
| result should carry low confidence. | ||
|
|
||
| ## Hypothesis Discipline | ||
| - Investigate **one hypothesis at a time**. Each diagnostic query must be designed to | ||
| confirm or refute a single, specific hypothesis — not to fish broadly. | ||
| - Explicitly state whether a hypothesis is `confirmed`, `refuted`, or `inconclusive` | ||
| based on the query evidence. A `hint` (`conclude`, `next-hypothesis`, or | ||
| `refine-query`) may accompany a verdict, but it is **advisory only** — in this | ||
| architecture the PLANNER, not the analyst, makes the binding decision about what | ||
| happens next, weighing the full accumulated evidence rather than a single step. | ||
| - Do not declare a root cause until at least one hypothesis has been confirmed by | ||
| direct query evidence, or until all reasonable hypotheses have been exhausted (in | ||
| which case say the investigation was inconclusive — do not guess a root cause). | ||
|
|
||
| ## Planner Direction (Opus-tier) | ||
| - The planner directs the investigation one turn at a time. On every turn it must | ||
| choose exactly one action: `gen_query` (propose the single best next hypothesis to | ||
| test), `read_repo` (the pipeline code/DAG itself needs deeper inspection before a | ||
| useful query can be written), or `conclude` (the evidence already confirms a root | ||
| cause, or no untested hypothesis is worth the cost of another query). | ||
| - When choosing `gen_query`, propose exactly one hypothesis — never a batch. Ground it | ||
| in the pipeline's actual DAG/tables and in what the evidence-so-far has ruled in or | ||
| out; do not re-propose a hypothesis already `confirmed` or `refuted`. | ||
| - Choose `conclude` as soon as further querying is unlikely to change the outcome — | ||
| either because a hypothesis is solidly confirmed, or because the remaining | ||
| hypotheses are all low-confidence and testing them would not be worth the cost. | ||
|

@pratyaksh-mundra the pr looks good now. Can you please resolve the coderabbit comments left? Then we can merge |
Follow-up review after the first fix pass: Correctness / safety: - query-guard: reject EXPLAIN ANALYZE (it executes + scans data in Athena/Trino) while still allowing non-executing EXPLAIN; prompt updated to match. - compactor: distinct-value keying no longer throws on nested bigint/cyclic values (honors the no-throw contract) and no longer conflates 1 and "1"; computeDateSpan now scans all rows so the reported span is full-result. - demo-reasoner: analyzeVolume returns "inconclusive" instead of a false "refuted" when no usable order_count series is available (mirrors the anti-join guard). - demo-executor: reuse the shared MAX_ROWS from athena-client so demo and live use one row ceiling. - lamatic-client: callFlow now has a hard Promise.race timeout so a hung flow can't block the caller forever. - analyst flow: tighten trigger advance_schema to require the compact nested fields and bound result.sampleRows (<=10), enforcing the compaction boundary at the transport edge. Prompt-injection hardening: - planner prompt: describe the metadata-only pipeline (files[] has no content) actually sent by the client. - reporter/repo-reader/analyst prompts: mark every injected investigation field as untrusted data, delimit the reporter payload as evidence, and require injection attempts to be noted in caveats[]. UI / build: - tailwind-merge bumped to v3 (Tailwind v4 compatible) so cn() overrides actually merge; form migrated to react-hook-form + zod. - replace hardcoded palette colors with semantic CSS-variable tokens (destructive/violet/info); darken light-theme success/warning for WCAG contrast; add an info token. - next.config: add outputFileTracingRoot so the demo scenario assets trace into the standalone build. - glue-client: cap listTables; fix stale ARCHITECTURE.md doc reference. Verified: tsc clean, next build clean (lint+types enforced), offline demo investigation still reaches the planted root cause end-to-end.

Adds kits/sparktrace/infra/ — optional infrastructure-as-code to stand up the live-mode backend and tear it down cleanly. Demo mode still needs none of it. - cloudformation/sparktrace.yaml: S3 bucket (sample data + auto-expiring Athena results), Glue Data Catalog databases (raw, finance) + the three scenario tables, a dedicated read-only Athena workgroup with a hard per-query bytes-scanned cap (10 MB, the AWS minimum), and an optional least-privilege read-only IAM user for the app. - bin/: up.sh (validate + deploy + upload data + write app .env.local), down.sh (empty bucket + delete stack), status.sh, smoke.sh (one capped read-only query proving the live path), write-env.sh (merges the AWS block into apps/.env.local without touching Lamatic keys), lib.sh. - Cost-safe by construction: nothing bills hourly; Athena is per-query and capped, so a full run costs a fraction of a cent. - Secrets: infra/.env (deployer keys) and the generated apps/.env.local are gitignored; only .env.example is committed.

The Trivy AWS-0143 note (inline policy on an IAM user) is intentional here — it's a single-purpose demo user scoped to exactly these read-only actions, so an inline policy is the least-moving-parts choice. @coderabbitai please re-review. |

Mission: distinguish a missing stack from an AWS error.
stack_status returns DOES_NOT_EXIST for every describe-stacks failure. If AWS returns AccessDenied, throttles the request, or has a transient failure, down.sh reports success and leaves deployed resources running.
Return the sentinel only for the exact missing-stack error. Fail for every other AWS error.

Missed mission: do not publish the generated access-key secret.
AppSecretAccessKey exposes AppAccessKey.SecretAccessKey in CloudFormation Outputs. bin/write-env.sh reads this via aws cloudformation describe-stacks, so any principal with stack-read access can retrieve it. status.sh only hides the value in its local terminal output. Store the app secret with deployment-only access or use an app role for the app instead of publishing the static secret.

Already supported by the AWS CLI's default credential resolution when set, but wasn't documented in the template. Useful for assumed-role deployer sessions.
Found while deploying the stack end-to-end against a live account: - lib.sh/up.sh: add an `awspath` helper (cygpath -m when available) for paths handed to the AWS CLI. On Git Bash/Cygwin/MSYS the shell emits POSIX paths (/cygdrive/f/...) that the native Windows aws.exe cannot open, so validate-template, deploy and `s3 cp` all failed. No-op on Linux/macOS. - write-env.sh: stage the temp file beside the target instead of $TMPDIR — keeps the final mv on one filesystem (atomic) and works where /tmp is not writable; clean it up on exit. Verified: stack reaches CREATE_COMPLETE, sample data lands in S3, and bin/smoke.sh runs the anti-join on real Athena — returning exactly the planted bug (3 dropped orders on each of the 3 most recent days), scanning 4,946 bytes against the 10 MB cap.

SparkTrace — agentic Spark pipeline debugging copilot
Adds
kits/sparktrace/, a kit that debugs broken data pipelines the way a data engineer would. Point it at a pipeline repo and describe a symptom ("daily revenue is ~30% low for the last few days") and it runs an investigation: reads the pipeline, forms hypotheses, writes read-only diagnostic SQL, executes it, and traces the root cause from the evidence.What makes it different
LIMIT; live mode also sets an Athena bytes-scanned cutoff.Reproducible for review — no credentials needed
The kit ships a demo mode that runs the entire investigation fully offline: a bundled "broken pipeline" scenario (a daily-revenue job that inner-joins to a lagged customer dimension and silently drops recent orders), a deterministic reasoner, and an in-process SQL engine (alasql) over sample CSVs.
cd apps && cp .env.example .env.local && npm install && npm run dev, pick the demo scenario, and the planner reaches the planted root cause — with zero Lamatic/AWS calls.Structure
type: "kit"with 5 tiered flows (planner,repo-reader,query-gen,analyst,reporter), their prompts + model-configs, a read-only constitution, the sample scenario underassets/, and a Next.js app (apps/) housing the orchestrator, query guard, compactor, AWS clients, demo engine, and UI.tscandnext buildpass; the offline demo investigation is verified end-to-end.Submitted for the agentkit-challenge.
