Overview

Adds the License Compliance Auditor kit (kits/license-compliance-auditor/) — an automated template that scans a project's dependency licenses, flags copyleft/GPL-family risk against a configurable allow-list, and generates a markdown compliance report. Problem statement checked against every merged kit and all historical agentkit-challenge PR titles — no overlap found.

Flow Architecture

  1. GraphQL Trigger (triggerNode_1): Accepts dependency_licenses (a JSON array of {name, version, license} — the standard output shape of tools like license-checker --json or pip-licenses --format=json) and an optional allow_list (comma-separated SPDX ids).
  2. Code Node Classifier (codeNode_210): Deterministic JS logic that normalizes each license string, merges the default allow-list (MIT, Apache-2.0, BSD-2/3-Clause, ISC, 0BSD, Unlicense, CC0-1.0) with any caller-supplied allow-list, and classifies every dependency as OK, BLOCKED (copyleft/high-risk: GPL/AGPL/LGPL/SSPL/etc.), or REVIEW_NEEDED (missing/unrecognized license). No LLM involved in the classification itself, so there are no hallucinated verdicts.
  3. LLM Report Generation (LLMNode_430): Gemini consumes the structured findings (wrapped in an untrusted-data tag to guard against prompt injection) and writes a markdown compliance report: Status / Blocked Dependencies / Needs Manual Review / Compliant Summary / Remediation Steps / Conclusion.
  4. Response Node (responseNode_triggerNode_1): Returns the generated report via a wired outputMapping.

Validation & Testing

  • node samples/test_classifier.js — local, no-deployment-needed self-check asserting the classification logic against a realistic fixture (MIT → OK, GPL-3.0 → BLOCKED, missing license → REVIEW_NEEDED). Passes.
  • Manually verified every @prompts/…, @scripts/…, @model-configs/…, @constitutions/… reference in flows/license-compliance-auditor.ts resolves to a file that exists in the kit.
  • No .env/.env.local committed — only samples/.env.example with placeholders.
  • samples/test_flow.js provided as a live smoke test against a deployed flow endpoint (not run in CI — requires real credentials).

Scope

All changes are contained to kits/license-compliance-auditor/. No other kit or repo-level file is touched.

  • Added the license-compliance-auditor kit and its configuration:
    • .gitignore
    • lamatic.config.ts
    • agent.md
    • constitutions/default.md
    • README.md
  • Added the flow definition at flows/license-compliance-auditor.ts.
  • Added flow resources:
    • Gemini model configuration.
    • System and user prompts.
    • License classifier script.
  • Added sample and test files:
    • Dependency license fixture.
    • Environment template.
    • Classifier regression test.
    • Deployed-flow smoke test.
  • The flow contains four nodes:
    • triggerNode_1 (triggerNode) accepts dependency data and an optional allow-list.
    • codeNode_210 (dynamicNode) validates and classifies licenses.
    • LLMNode_430 (dynamicNode) uses Gemini to generate the Markdown report.
    • responseNode_triggerNode_1 (responseNode) returns the report, counts, violation status, and findings.
  • The flow processes requests in this order: trigger → classifier → report generator → response.
  • The classifier supports flat SPDX OR and AND expressions and returns REVIEW_NEEDED for unsupported or malformed expressions.
  • Tests cover normalization, GPL-family identifiers, HTML escaping, compound expressions, and expected fixture results.

Inline comments:
In `@kits/license-compliance-auditor/flows/license-compliance-auditor.ts`:
- Line 62: Update the advance_schema definition near the dependency license
inputs to include the deployment-mode field, then propagate that value through
the classifier and report prompt so deployment-specific license policy is
applied. Preserve the existing dependency_licenses and allow_list fields and
their current behavior.
- Around line 40-42: Add the missing production classifier script referenced by
license_compliance_auditor_code_node_210_code under the scripts location, or
update that reference to the existing checked-in classifier file; ensure the
resolved path matches the asset included for deployment.

In `@kits/license-compliance-auditor/README.md`:
- Line 25: Update the documentation to describe dependency_licenses consistently
as a JSON-encoded string, matching the string schema in
triggerNode_1.data.values.advance_schema and the raw JSON sent by
samples/test_flow.js. Apply this wording in
kits/license-compliance-auditor/README.md:25-25 and
kits/license-compliance-auditor/agent.md:15-15; no flow or sample changes are
needed.
- Line 28: Update the kit’s response mapping so the classifier’s structured
findings—summaries, counts, and policy violations—are returned alongside
LLMNode_430.output.generatedResponse as the markdown report. Keep the report
field intact, and revise the sample and README documentation to reflect the
expanded structured compliance result.
- Line 7: Update the classification vocabulary in the README.md line 7 and
agent.md line 9 to use the public status values PERMITTED, RESTRICTED,
FORBIDDEN, and UNKNOWN consistently, replacing OK, BLOCKED, and REVIEW_NEEDED
without changing the surrounding behavior or documentation scope.
- Around line 17-19: Update the README and compliance prompts to describe
results as screening guidance, not legal advice: state that outcomes depend on
license version, intended use, distribution model, and applicable exceptions;
require legal review before making the final shipping decision; preserve the
sample’s “may require” wording; and clarify that BLOCKED is a conservative
policy classification, not a deterministic legal prohibition.

In `@kits/license-compliance-auditor/samples/test_classifier.js`:
- Line 22: Update the license-expression parsing and classification flow in the
classifier so it evaluates every SPDX alternative instead of selecting only the
first term. For OR expressions, allow the dependency when any operand is
allow-listed; for AND expressions, retain and enforce obligations from all
operands. Add assertions covering both operand orders, including GPL-3.0 OR MIT
and MIT OR GPL-3.0.

In `@kits/license-compliance-auditor/samples/test_flow.js`:
- Line 47: Update the timeout lifecycle in the fetch flow so the timer remains
active through response-body reads such as response.text() or response.json().
Move the clearTimeout call currently in the finally block to execute only after
the complete response-processing promise settles, while preserving cleanup for
both success and failure paths.
- Line 39: Validate that API_URL uses the https: protocol before the fetch
request sends the Authorization bearer credential. Reject non-HTTPS values from
LAMATIC_API_URL before entering the fetch flow, while preserving the existing
request behavior for valid HTTPS endpoints.

Thanks for the review! Pushed a fix commit addressing the feedback:

Fixed:

  • Missing scripts/license-compliance-auditor_code-node-210_code.ts reference — the file was already added in the previous commit (it was originally excluded by this repo's root .gitignore bare scripts rule, which silently drops any kit's scripts/ folder unless force-added).
  • Classifier only inspected the first term of SPDX compound expressions — now correctly handles OR (dual-licensed: OK if any operand is allow-listed) and AND (compound: BLOCKED if any operand is copyleft), with new test cases for both operand orders (GPL-3.0 OR MIT and MIT OR GPL-3.0).
  • Response outputMapping now returns structured findings (has_violations, total_deps, blocked_count, review_count, findings[]) alongside the markdown report, so a CI consumer can gate on has_violations without parsing prose.
  • README now clarifies dependency_licenses must be sent as a JSON-encoded string on the wire (matches the trigger's string schema type and samples/test_flow.js's actual behavior).
  • Added a "not legal advice" disclaimer to README, agent.md, and the report-generation prompt.
  • samples/test_flow.js: now rejects non-https:// API URLs before sending the bearer token, and keeps the abort timeout active through response-body reads instead of clearing it as soon as headers arrive.

Not changed (stemmed from the PR description, not the code): the "add a deployment-mode field to advance_schema" and "use PERMITTED/RESTRICTED/FORBIDDEN/UNKNOWN vocabulary" comments were flagging a mismatch against my first PR description draft, which I'd already rewritten to accurately match the actual code (2-field schema, OK/BLOCKED/REVIEW_NEEDED buckets) right before this review ran. The code was always internally consistent — no change needed there.

@coderabbitai review

…put, security hardening

- Classifier now correctly handles SPDX compound license expressions
  ("GPL-3.0 OR MIT" -> OK, "Apache-2.0 AND GPL-3.0" -> BLOCKED) instead
  of only inspecting the first term of the expression.
- Response node now returns structured findings (has_violations,
  total_deps, blocked_count, review_count, findings[]) alongside the
  markdown report, so CI consumers can gate on has_violations without
  parsing prose.
- README clarifies dependency_licenses must be sent as a JSON-encoded
  string on the wire (matching the trigger's string schema), matching
  samples/test_flow.js's actual behavior.
- Added a "not legal advice" disclaimer to README, agent.md, and the
  report-generation prompt.
- samples/test_flow.js: enforce https:// before sending the bearer
  token, and keep the abort timeout active through response-body reads
  instead of clearing it as soon as headers arrive.

In
`@kits/license-compliance-auditor/scripts/license-compliance-auditor_code-node-210_code.ts`:
- Line 18: Update the license normalization used by classify so compound SPDX
expressions are not reduced to their first operand: either parse and preserve
the complete AND/OR expression with correct semantics, or return REVIEW_NEEDED
whenever such an expression is encountered. Keep single-license normalization
unchanged and ensure MIT AND GPL-3.0 cannot produce OK while omitting the second
obligation.
- Around line 2-3: Update the rawDeps and rawAllowList assignments to read
runtime values through workflow.triggerNode_1.output rather than interpolated
Mustache expressions, so parseDeps receives the actual dependency_licenses data
and the allow list receives the actual allow_list value.

@ArekatlaNishanthchowdary Mission update: I verified the prior fixes by source inspection. The script reference exists, the response mapping contains the structured fields, the documentation matches the string input schema, and the smoke test keeps its timeout through response-body reads.

One finding remains:

  • classify() does not parse nested or mixed SPDX expressions. It splits on OR first and treats the remaining AND expression, including parentheses, as one license identifier. For example, GPL-3.0 OR (MIT AND Apache-2.0) returns REVIEW_NEEDED. The MIT AND Apache-2.0 branch is an approved alternative, so the expected result is OK. Likewise, GPL-3.0 AND (MIT OR Apache-2.0) returns REVIEW_NEEDED instead of BLOCKED. Line 91 of kits/license-compliance-auditor/scripts/license-compliance-auditor_code-node-210_code.ts causes this behavior. Either implement precedence-aware parsing for parentheses and mixed AND/OR, or restrict the documented support to flat expressions. Add matching tests because samples/test_classifier.js currently covers only flat expressions.

I did not execute repository code or tests.

Re: the review on 9932e4a→e0b9b564 (2 actionable comments) — both are already addressed by the next commit, 43c9642, which this review predates:

  1. Compound SPDX expressions reduced to first operand — fixed in 43c9642. classify() now evaluates the full OR/AND expression (dual-licensed OK if any operand is allow-listed, compound AND BLOCKED if any operand is copyleft) instead of only inspecting the first term. Covered by new test cases in samples/test_classifier.js for both operand orders.

  2. {{triggerNode_1.output.x}} templating instead of workflow.triggerNode_1.output.x — this is intentional, not a bug. It's Lamatic's own runtime template-substitution syntax for codeNode scripts (documented in this repo's CLAUDE.md: "Uses {{nodeId.output.x}} Lamatic template variables that resolve at runtime"), and it's the exact same pattern used in the already-merged reference kit kits/api-breaking-change-detector/scripts/api-breaking-change-detector_code-node-676_code.ts (const rawV1 = {{triggerNode_1.output.v1_schema}};). The engine substitutes these before the script runs as plain JS — workflow.triggerNode_1... isn't valid Lamatic template syntax.

@ArekatlaNishanthchowdary: Mission report complete.

Commit 43c96427 fixes the original first-operand issue for flat SPDX expressions. The classifier now evaluates all operands in flat OR and AND expressions. The sample checks cover both OR operand orders and flat AND cases.

The {{triggerNode_1.output.x}} finding was incorrect. CLAUDE.md documents this Lamatic runtime template syntax. The reference kit uses the same syntax. workflow.triggerNode_1... is not the applicable syntax.

One separate finding remains. The classifier does not parse nested or mixed expressions. For example, GPL-3.0 OR (MIT AND Apache-2.0) still produces REVIEW_NEEDED because the OR branch treats MIT AND Apache-2.0 as one license identifier. The current tests do not cover nested expressions.

I inspected the source only. I did not execute repository code or tests.

Learning: In Lamatic kit code-node scripts, `{{nodeId.output.x}}` is documented runtime template syntax that resolves before JavaScript execution. Do not flag this syntax as invalid JavaScript. The established reference script `kits/api-breaking-change-detector/scripts/api-breaking-change-detector_code-node-676_code.ts` uses `{{triggerNode_1.output.v1_schema}}` and `{{triggerNode_1.output.v2_schema}}`.

Thanks for catching this — you were right, and it was worse than the example showed. Traced it locally: `GPL-3.0 AND (MIT OR Apache-2.0)` was actually resolving to `OK` (not just `REVIEW_NEEDED`), because the naive `/\sOR\s/i` substring check fired on the nested OR even though it's under a top-level AND, then split the string incorrectly and silently dropped the GPL-3.0 obligation. That's a genuine false-negative, not just an edge-case gap.

Fixed in 05ee56b: any expression containing parentheses (after stripping one fully-wrapping outer layer) or mixing both `AND`+`OR` is now detected up front and routed to `REVIEW_NEEDED` — never guessed at. Added regression tests for both directions (`GPL-3.0 AND (MIT OR Apache-2.0)` and `GPL-3.0 OR (MIT AND Apache-2.0)`, both now correctly `REVIEW_NEEDED`), and documented the flat-expressions-only limitation in the README's Tradeoffs section as a deliberate scope boundary rather than a silent gap.

@coderabbitai review

classify() only parsed flat "A OR B" / "A AND B" expressions correctly.
For nested/parenthesized expressions like "GPL-3.0 AND (MIT OR
Apache-2.0)", the naive substring-based OR/AND detection fired on the
nested operator and mis-split the string, in one traced case silently
returning OK for an expression that should be BLOCKED (the GPL-3.0
obligation was dropped). Nested or mixed expressions are now detected
up front and routed to REVIEW_NEEDED instead of guessed at, per
CodeRabbit review feedback on PR Lamatic#404.

@ArekatlaNishanthchowdary: Mission verified.

Commit 05ee56bf contains the fix. In classify(), the nested-or-mixed expression guard runs before the OR and AND split logic. This prevents the reported false-negative for GPL-3.0 AND (MIT OR Apache-2.0).

The regression tests cover both reported expressions. The README documents the flat-SPDX-expression scope boundary.

I inspected the source only. I did not execute repository code or tests.

Good catch on the paren-stripping logic — verified locally and it was a real bug, not just style: `stripParens("MIT)")` returned `"MIT"` (silently stripping an unmatched trailing paren), which would have let a malformed license string slip past the nested-expression guard and get classified as a plain valid license instead of `REVIEW_NEEDED`. `stripParens("(MIT) OR (GPL-3.0)")` also mangled into `"MIT) OR (GPL-3.0"`.

Fixed in 0a4a964: `stripParens` now does a proper depth-scan to confirm the leading `(` and trailing `)` are a genuine matching outer pair before stripping — anything unbalanced or multi-group is left untouched so the nested-expression guard catches it. Added regression tests for both cases. Also fixed the README markdownlint MD031 spacing issue (and a couple more instances of the same missing-blank-line pattern elsewhere in the file, to avoid another round-trip on the same rule).

@coderabbitai review

stripParens() used /^\(|\)$/g, which independently strips a leading "("
or trailing ")" even when they don't form a matching pair. This let
malformed license strings slip past the nested-expression guard — e.g.
"MIT)" silently normalized to "MIT" and was classified as a plain
valid license instead of REVIEW_NEEDED — and mangled multi-group
expressions like "(MIT) OR (GPL-3.0)" into "MIT) OR (GPL-3.0)".

Now only strips a single pair when it's confirmed to be a genuine
fully-wrapping outer match (depth-scanned), leaving anything else
untouched so the nested-expression guard catches it correctly. Also
fixes a markdownlint MD031 (missing blank lines around fenced code
blocks) flagged in README.md.

Per CodeRabbit review feedback on PR Lamatic#404.

@ArekatlaNishanthchowdary Your mission is complete.

I verified commit 0a4a9644 by source inspection. stripParens() now removes an outer pair only when that pair wraps the complete expression. Unmatched parentheses and separate parenthesized groups remain in the expression.

The classifier then detects the remaining parentheses and returns REVIEW_NEEDED. The regression checks cover MIT), (MIT, (MIT) OR (GPL-3.0), and the malformed-license classification path.

The README also includes the required blank lines before fenced code blocks.

I did not execute repository code or tests.

Following up — your 2026-09-13 11:52 UTC comment confirmed commit 0a4a964 (still the branch head) has no remaining actionable issues, but that came through as a rate-limited comment reply rather than a formal review, so the PR's formal review state is still stuck at CHANGES_REQUESTED from an earlier commit and the passing-checks label got pulled by the cron job as a result.

Requesting a fresh formal review now that the rate limit should have reset.

@akshatvirmani all CodeRabbit threads are now replied to and resolved (0 open), and validate passes on e8d34ac.

One thing on the repo side: the "Validate PR — Studio runtime check (Phase 2, testing)" run for this push failed in 4s at the checkout step, before touching the kit: https://github.com/Lamatic/AgentKit/actions/runs/38234291755

Refusing to check out fork pull request code from a 'workflow_run' workflow. [...] To opt in, review the risks at https://gh.io/securely-using-pull_request_target and set 'allow-unsafe-pr-checkout: true' on the actions/checkout step.

So it looks like a workflow configuration issue that will affect any fork PR rather than something in this kit (the earlier /validate Studio check on 23 Sep passed). Let me know if you need anything else from my side before merging.
