Tool names and descriptions exactly as the server reported them on Nov 9, 2026. The maker wrote them, not us; we show them as plain text.
get_instructionsGet the VarynForge agent guide — workflow paths (free vs paid), token-economy rules, walls and upgrade conversation conventions. Read this at session start.
get_changelogGet the URL of the VarynForge product changelog — what shipped, newest first, in plain markdown. Fetch it when the operator asks what is new, and in the days after a send_feedback report to check whether the gap they hit has been closed.
get_writer_system_promptGet the writer system prompt for drafting one content type from its brief. The writer works with your Varyn account context: every channel prompt binds to the brief, its acceptance rubric, and the opportunity behind the brief fetched from the account, and degrades to generic writ
get_account_statusGet the operator account status — the organization whose plan/credits/limits this payload describes (plans and usage limits are per-organization; see list_organizations), current plan, available credits, brief quota state, the lint_draft daily verification cap (applies on every t
list_organizationsList the organizations this account belongs to — id, name, your role (owner | admin | member), is_personal, plan, and member_count — plus pending invitations awaiting a response (accept them in the web app). Plans, credits, and usage limits are per-organization, and a project bel
get_onboarding_guideDiagnose where the operator is in their VarynForge journey and get a guided setup path. Call when the operator asks to set up VarynForge, get started, or seems unsure what to do next — and always when list_projects returns empty. Returns the server-derived stage, a stage-tailored
send_feedbackFile a note to the VarynForge team: a bug, a missing capability, a friction point, or an operator idea. Call when you hit something VarynForge cannot do, a confusing tool result, or the operator voices frustration or a wish. Whenever the task would benefit from a capability this
create_projectCreate a new project — pass either a website URL or a niche description (or both). Returns projectId immediately; niche analysis and asset mapping run async. Poll get_project until niche.analysisStatus is ready. When the operator says whose site this is, pass siteRelation: mine (
get_projectGet one project — its canonical name (operator-set, falling back to site brand then niche name), niche profile, target audience, current research status, and postsPerWeek (the operator’s publishing cadence, settable via set_posting_cadence; sizes the pitch report’s 90-day sequenc
get_project_assetGet the asset (website/product) associated with a project — URL, name, description, solution profile.
update_nicheUpdate a niche profile — name, industry, language, country, target customer, core problem, related terms. Use after the operator refines their market definition; omitted fields keep their current values.
list_destinationsList the project's destinations — where the operator publishes (website, youtube_channel, tiktok, instagram, x, linkedin, local_business). Destination type ids are the `format` labels lint_draft stores drafts under. Each row carries its capabilities so you never cross-reference o
add_destinationAdd a destination to a project — where the operator publishes. Pass `type` (website | youtube_channel | instagram | tiktok | x | linkedin | local_business) and `name` with `state: 'detected'` for a destination that already exists and belongs to the operator (website name = the do
list_competitorsList companies for a project — marked competitors (important / default / ignored) and SERP-discovered companies (unmarked). Sorted important → default → unmarked → ignored, then by domain. Pass `importance` to filter to one bucket. Capped at 100.
set_competitor_importanceMark a competitor important, default, or ignored. Important applies a 1.25× boost on opportunity scores for clusters where the competitor ranks top-10. Scores are then normalized 0-100 against the highest-scoring cluster, so other clusters may appear to drop in relative ranking e
add_competitor_by_domainAdd a competitor to a project by domain (e.g. example.com). Marks the competitor as important or ignored on creation.
update_asset_profileCorrect the inferred profile of the project asset — description, primary offer, benefits, key differentiators, use cases. Use when get_project_asset shows claims that contradict what the operator actually sells (profileStaleAt set, or the operator says so). Only the fields you pa
set_posting_cadenceSet how many articles per week the operator actually publishes (1-14). Sizes the pitch report’s 90-day content sequence; read back via get_project.postsPerWeek.
resync_asset_profileRe-read the project website and re-infer the asset profile (name, description, primary offer, benefits, differentiators, use cases) from its current content. Use before rendering a report when get_pitch_report_payload flags assetProfile.syncedBeforeRun — the stored profile facts
remap_assetRe-crawl the project website and refresh its owned pages. Use when get_project_asset shows mappingStatus "error" or owned pages look stale. Rate-limited per site; returns an error naming the wait time if the cooldown is active.
start_research_runStart a research run for a project — discovers keywords, evaluates competitors, and writes opportunity clusters. Consumes one credit. Returns `{ runId }`; poll get_research_status for progress. Returns `{ entitlement }` instead when the operator is on the free plan.
list_projectsList all projects for the authenticated operator — paginated, sortable by createdAt, niche, or industry. `name` is the canonical project name (operator-set, falling back to site brand then niche name) — match operator references against it; `niche.name` is the market niche, disti
get_competitor_detailGet a competitor company detail in a project context — domain, name, importance, top pages in the project SERPs, and top keywords they rank for.
get_project_overviewGet the at-a-glance read on a project — niche summary, keyword stats, nextActions (the ranked queue of what to do next in this project — offer its first entry when the operator asks "what now?"), and topPriorities: the ranked queue of article suggestions (best first — prioritySco
get_research_statusPoll the latest research run for a project — runId, status, current pipeline phase, progress percent, elapsed seconds, and structured failure diagnostics when failed. failure carries failureClass (upstream_timeout | upstream_rate_limited | invalid_input | internal | unknown), the
get_pitch_report_payloadAssemble the client-ready pitch report payload for a completed research run — niche + solution profile, competitor landscape, ranked opportunity map holding GAPS ONLY (0-100 normalized; demand sized as volumeBucket buckets, no search-volume numbers by design; each entry carries o
get_starting_point_reportGet the free starting-point report for a project — a client-facing document assembled from setup-time data: positioning (niche + market profile), the site and its current content inventory, the curated competitor set, and early rising-topic signals. Free on every plan, no researc
list_opportunitiesList content opportunity clusters sorted by opportunity score. Goal filters: fast_wins, high_intent, authority_building, competitor_gap. coverage filters by site-coverage status and defaults to ["gap","partial"] — clusters the site already COVERS (ranks top-10 for a cluster keywo
get_opportunity_detailGet a cluster detail — top-20 keywords by score, top-10 ranked pages by position, top-5 competitor podium, linked article suggestions, and rawOpportunityScore (un-normalized; list_opportunities returns the 0-100 normalized version).
set_opportunity_statusDismiss or restore an opportunity cluster. status=dismissed hides it from list_opportunities and the create_content_plan_from_opportunities harvest; status=default restores it. Dismissal lasts until the next research run rewrites the project clusters — for a durable "not my produ
set_excluded_termsSet the project-level exclusion terms — products or topics the operator explicitly does NOT sell (e.g. "wedding suite", "free template", "printing"). Keywords mentioning any term are down-weighted in opportunity scoring and dropped from the content-plan harvest, before results re
list_keywordsList keywords tracked for a project — text, difficulty, intent, volume bucket (no_traffic | long_tail | average | high). Paginated; supports sorting and intent filter.
get_keyword_detailGet a keyword detail — pages ranking for it with positions and ownership, plus related keywords already tracked in the project.
list_pagesList ranked pages tracked for a project — URL, title, company, query count, ownership. Filter by ownership or company domain.
get_page_dossierGet a page dossier — URL, title, project rankings, ownership. `headingOutline`, `targetKeywords`, and `contentAnalysis` populate for owned (asset-mapped) pages only.
list_article_suggestionsList article suggestions for a project — title, status, priority, cluster, intent, source, publishedAt, scheduledFor, and a per-channel distributions rollup ({ channel, count, latestAt, scheduledFor } per channel the content went out on). Use distributions to spot gaps from the l
create_content_plan_from_opportunitiesCreate a content plan by harvesting the top-30 opportunity clusters from a completed research run. Auto-creates article suggestions linked to each cluster. Left out of the harvest: dismissed clusters (set_opportunity_status), keywords matching the project exclusion terms (set_exc
add_article_suggestionAdd a bare article suggestion to a content plan (title + optional intent and reasoning). For richer input that produces a brief-ready suggestion, use create_article_suggestion_with_input.
create_article_suggestion_with_inputCreate a brief-ready article suggestion from the operator's own input. Auto-resolves a default content plan; creates/links search-query rows for the keywords; returns suggestionId + contentPlanId. Free-tier compatible (no research run required).
update_article_statusMove an article through the production pipeline. Statuses: planned, generating_brief, brief_ready, drafting, draft_ready, reviewing, ready_to_publish, published. For the published transition use mark_article_published instead — it records the live URL, which Search Console outcom
generate_article_briefForge a writer-ready brief from an article suggestion. `channel` picks the brief template: article (default, SEO article outline), reels (hook/beats/shot list), youtube (retention beats/chapters), x (thread posts), linkedin (carousel slide deck: cover hook, one-idea slides, recap
get_article_suggestionGet article suggestion details — metadata, cluster context, brief availability, registered derived assets (carousels, social posts), target keywords with volumes. Call get_article_brief for the full brief. Status semantics: generating_brief with briefQueuedAt set means the brief
get_draft_statusRe-read an article suggestion's verification state without re-linting: the suggestion's single pipeline status plus, per destination `format`, the stored draft and the latest gate receipt (verdict, per-check detail, thresholds) from its last lint_draft submission. Free and uncapp
get_article_briefGet the full content brief for an article suggestion. A suggestion holds one brief per channel — pass `channel` (article default | reels | youtube | x | linkedin) to pick which. Every brief carries hookStatement (one verbatim-usable hook sentence naming the reader payoff); articl
delete_article_suggestionDelete an article suggestion and its associated brief. Cascades to keyword and cluster links.
download_brief_markdownGet a brief as inline markdown the host agent can use as a writing prompt. Pass format=markdown_inline, and `channel` (article default) to pick which of the suggestion’s per-channel briefs to render. Returns the brief assembled into a single markdown string capped at ~8K chars —
mark_article_publishedRecord that an article went live at a URL. Flips the suggestion to published, writes the distribution ledger row, stamps the Passport, and pings IndexNow. Call it only once the URL actually resolves — the IndexNow ping fires immediately, and a ping for a dead URL is wasted (searc
register_derived_assetRegister a derived asset (LinkedIn carousel PDF, social post, video, image) produced from an article suggestion. Appends a distribution-ledger row so the suggestion shows everything it produced — the article plus its derivatives — for content-ROI reporting (get_article_suggestion
get_lint_rubricGet the verification rubric for an article suggestion: the submission format for the channel (markdown | --- separated thread | post-with-slides | production script), required vs advisory checks, the exact numeric limits each check grades against (checkParams), plus the brief fie
lint_draftSubmit a draft for verification against its brief. Returns a pass/flag verdict with per-check detail. Pass moves the article to ready_to_publish; flag moves it to draft_ready for revision. `channel` (article | reels | youtube | x | linkedin) declares WHICH of the suggestion's per
get_write_handoffOne-call writer handoff: returns a compact writing payload for an article suggestion (brief essentials, keywords, acceptance criteria, lint instructions). Compact by design — FAQs cap at 6 and long sections degrade to fit a deep-link budget; the FULL brief is get_article_brief an
expand_ideaScore a raw article idea against the project's niche without writing anything to the plan. Returns a title, angle, search intent, related queries, a coarse demand estimate, and a 0-100 niche-fit score. Pass the returned fields to accept_idea to commit the idea as a brief-ready su
accept_ideaCommit an expanded idea (from expand_idea) to the content plan as a brief-ready article suggestion. Stores the verbatim idea as provenance, lands the suggestion in generating_brief, and forges its brief automatically (free tier: queues past the daily cap). Returns the new suggest
check_ideaAttach real search data to one article idea that is already in the project — runs one live Google search per target keyword and returns volume bands and the pages currently ranking for each. Use after create_article_suggestion_with_input, or on any existing suggestion the operato
list_radar_topicsList the latest emergent-topic radar snapshot for a project: rising narrative topics (label, summary, momentum, novelty, drivers, evidence) with per-topic index and how many article suggestions were already added from each. Returns null when the project has no radar snapshot yet.
expand_radar_topicExpand one radar topic (by signalObservationId + topicIndex from list_radar_topics) into 3-6 candidate article angles with title, intent, and editorial positioning; each angle is flagged when a near-duplicate already exists in the content plan. Optionally pass customPov for angle
add_radar_topicAdd selected angles from a radar topic to the content plan as radar-born article suggestions (provenance preserved; exact-title duplicates skipped). Angles come from expand_radar_topic; call list_radar_topics first to get signalObservationId + topicIndex. Auto-creates the content
