vendor-inventory-stinger

# Vendor Inventory Stinger > **Forge status:** stages 1-6 complete (Topic, Research, Distillation, References, Guides, final > Skill/Bee authorship). Stage 7 (Register: beekeeper-suit registration and cross-harness deploy) > has not run yet. ## Purpose Equips **vendor-inventory-worker-bee**, wave W1b of every Website Auditor by Legion Code Inc. engagement, to enumerate every third-party script, tag, pixel, and iframe present on the audited landing page after a real headless-browser load, including anything Google Tag Manager hydrates at runtime, and to flag content-injection/metadata-manipulation tooling (Search Atlas's OTTO Pixel and peers) as its own category. Full scope and acceptance criteria: [prd-004-vendor-inventory](../../library/requirements/backlog/prd-004-vendor-inventory/prd-004-vendor-inventory-index.md). Every factual claim this skill makes traces to a downloaded primary source in `references/research/raw/` or to this pair's PRD/the build plan. The archive covers only Google Tag Manager and Search Atlas in real depth, two sources total; everywhere else (the broader vendor lookup table's judgment-call rows, and the Search Atlas detection signature itself, which the vendor's own page never documents) that gap is named explicitly, never smoothed into an unstated guess. See `references/research/distilled-vendor-inventory.md` and `references/vendor-lookup-table.md`. ## When to use this skill - Wave W1b of every audit run, in parallel with `stack-fingerprint-worker-bee` (wave W1a) - Flagging content-injection/SEO-manipulation tooling before an SEO/AEO audit runs, so `technical-seo-worker-bee` (prd-008) and `aeo-audit-worker-bee` (prd-009) know some on-page metadata may not be the client's own hand - Building the vendor list `analytics-stack-worker-bee` and `web-security-posture-worker-bee` later interpret ## When not to use - Judging whether a detected vendor is good or bad, or a security/analytics risk, that belongs to `analytics-stack-worker-bee` and `web-security-posture-worker-bee` downstream, this Stinger only inventories, per PRD-004's explicit non-goal - Classifying the site's technology stack or render mode, that is `stack-fingerprint-stinger`'s job (its sibling wave, not this one) - Any step that would create state on the target (order placement, form submission, auth bypass, file upload), which defaults OFF and requires explicit per-run opt-in ## Procedure 1. Read `00-intake/` for the target URL and `_shared/target-profile.json` for render-mode context (a CSR/hybrid site's real vendor list only appears after JS execution). If `target-profile.json` does not exist yet, proceed anyway, the two wave-W1 Bees run in parallel by design. 2. Perform a real, read-only, JS-executed headless-browser load and capture the third-party network request log, DOM `<script src>` list, and rendered HTML, per `guides/01-headless-capture-procedure.md`. 3. Detect Google Tag Manager first, using all seven researched signals across three channels, then cross-reference every other vendor row against the same page load rather than assuming GTM's presence explains anything away, per `guides/02-gtm-hydration-and-downstream-tags.md`. 4. Detect and flag content-injection/metadata-manipulation tooling (Search Atlas OTTO Pixel and peers) as its own category, labelled vendor-self-reported and `candidate, needs manual confirmation` since no raw source documents its detection signature, per `guides/03-injection-tool-detection.md`. 5. Classify every remaining vendor by function (analytics, tag manager, chat, payments, CRO/testing, SEO-injection, ads, consent/CMP, other) with evidence, per `guides/04-vendor-classification.md`. Run `shared/scripts/vendor-census.py` to apply the lookup table deterministically. 6. Write `01-recon/vendor-inventory.md`, cross-referencing the flagged content-injection findings for prd-008/prd-009 per PRD-004 AC-2, per `guides/05-write-vendor-inventory-report.md`. ## References map - `references/vendor-lookup-table.md`, load when applying or extending the vendor lookup table, or verifying a classification's grounding (researched vs. judgment call) - `references/templates/vendor-inventory-report-template.md`, load when writing `01-recon/vendor-inventory.md` - `references/templates/vendor-entry.template.json`, load when assembling the intermediate per-vendor row shape before writing the markdown report - `references/research/distilled-vendor-inventory.md`, load when a domain claim needs verification or this Stinger's coverage gaps need checking before making a claim - `references/research/raw/`, load when tracing a distilled claim back to its primary source - `references/scripts/README.md` and `shared/scripts/vendor-census.py`, load/run for the deterministic classifier that drives steps 3-5 of the procedure above ## Related bees and stingers - [vendor-inventory-worker-bee](../../agents/vendor-inventory-worker-bee.md) - this Stinger's paired Bee - [stack-fingerprint-stinger](../stack-fingerprint-stinger) - runs in parallel, wave W1a; this Stinger reads its `target-profile.json` for render-mode context - [audit-intake-stinger](../audit-intake-stinger) - wave W0, scaffolds the workspace this Stinger reads `00-intake/` from - [analytics-stack-stinger](../analytics-stack-stinger) - downstream consumer of this Stinger's vendor list; judges the analytics vendors this Stinger only inventories - [web-security-posture-stinger](../web-security-posture-stinger) - downstream consumer of this Stinger's vendor list; judges third-party risk this Stinger only inventories ## Critical Directive - You must read all files and context contained within your skill. - In the event your core knowledge does not provide sufficient guidance you must make every attempt to search the internet, related knowledge base documentation files, and other available resources to supplement your knowledge prior to proceeding with your task. - Additional related skills can be found here: - [stack-fingerprint-stinger](../stack-fingerprint-stinger) - parallel wave-W1 sibling; consult its `target-profile.json` for render-mode context before capturing ## Ship Gate Ship Gate removed: vendor-inventory-stinger performs a read-only external website audit and writes its output into the audited customer's `www.<domain>-audit/` workspace, not into this repository. It never produces a commit inside this repo as part of its own operation, so the Ship Gate (security-stinger, then quality-stinger, then github-repo-health-stinger) does not apply to this pair's runtime procedure. This is separate from the fact that changes to this plugin's own source (this file included) still go through this repository's normal Ship Gate before being committed, per the build plan's own development process, that gate governs building the plugin, not what the plugin does when it runs.
