Two former Skills were merged in on 2026-08-16 and deleted: backlink-analyzer (analysis templates, toxicity rubric, outreach — now in three references under its original Apache-2.0 licence) and browser-harvest (pulling tables out of logged-in dashboards — now <ref file="references/harvest.md"/>).

Without a key it falls back to the owner's own logged-in Chrome via OpenCLI, where a session hits a CAPTCHA / "unusual traffic" wall after roughly 4 operator queries, and a flagged exit IP gets blocked even from a fresh independent profile (2026-09-12 agent-browser finding).

Holding them open simultaneously would need N session names. </note> </recon> <caution> These metrics help discover and prioritize candidates. They never prove a backlink is public, indexed, followable, or causally producing traffic. The parsing traps that make a report silently return zeros are documented in <ref file="references/authorized-data-sources.md"/> — read it before writing any new reader, especially the rule that a readiness predicate must key on a data row, never on a tab name, column header, or filter chip.

Then check the parser against itself. A ready page and a correct parse are different claims, and the second one fails silently. One live run under-reported all five domains it touched — the worst lost 91 rows of 93, and the one that looked healthiest still lost 49 — with no error anywhere and a wrong written conclusion on top.

The check is two comparisons, and conflating them produces false alarms:

<check level="1" compares="rawText vs parsed.rows.length"> Count the record-shaped lines in `rawText`, compare with `parsed.rows.length`. A gap here means **your regex has a blind spot** — the rows arrived and you dropped them. This is the silent, dangerous one. Fix the parser. </check> <check level="2" compares="the page's own headline count vs rawText"> Semrush prints its own total (`自然搜索排名: N`). If that exceeds what `rawText` even contains, the rows **never reached you**: these tables are virtual-scroll and only mount a fraction at a time, so a full pull needs the export, which costs quota. This is a known ceiling, not a bug — say so rather than "fixed the parser". </check>

A live re-run shows both at once: three domains matched their headline exactly (14/14, 22/22, 5/5) while one read 91 against a claimed 430. The first three prove the parser; the fourth is level 2 and needs no fix. </caution> </workflow>

The division of labour is fixed: **scripts collect evidence, the AI reads the evidence and judges, a human can re-check both.** The batch scripts emit measured raw values plus a parse status, a raw-text excerpt, a screenshot in `&lt;out&gt;.jsonl.evidence/`, and a `stopReason` — never a pass/fail verdict. `apply-traffic-screen` copies numbers and evidence paths into the table; the threshold is computed at query time by `targets-select`. </statement> <read><ref file="references/traffic-screen.md"/></read> <cmd><![CDATA[ node scripts/similarweb-batch.mjs --domains-file domains.txt --out sw.jsonl # rows: {totalVisits, parse, stopReason, rawExcerpt, evidence:{screenshot,raw}} node scripts/apply-traffic-screen.mjs --in sw.jsonl --source similarweb node scripts/targets-select.mjs --cohort open --min-traffic 100 ]]></cmd> <caution> **A null value is NOT low traffic — it is an unmeasured or failed capture, and treating it as a conclusion is banned.** `stopReason` tells you which: `stable`/`empty-state` mean the capture completed (and `empty-state` means the source itself printed a no-data sentence — whether that means "too small to measure" is the AI's call, made against the screenshot and raw text); `unstable`/`timeout`/`exception` mean *this check did not finish* — resume retries them, and applying such a row clears any stale same-source measurement instead of writing one. Rows without a number never fall into the "unqualified" bucket: `targets-select --min-traffic` lists them separately and `--unmeasured` queues them. </caution> <headline> Measuring a domain costs one query; filling its form costs two orders of magnitude more. One run filled every form across a 73-domain family and only then sampled five for traffic — every filled form was discarded. </headline> </workflow> <workflow id="submit" when="a route exists and the target passed the screen"> <read><ref file="references/submission-lanes.md"/></read> <inspect> Inspect every target independently. Never infer a form from a sibling site. `inspect-page.mjs` outputs a **full form census** — every form, every field (visible and hidden) with its semantic tuple and stable marker — plus a captureScene pair (piercing census + screenshot) in the evidence dir. Its `fillable` / `blocker` / `reason` / `selectedForm` fields are **heuristic suggestions** (see the `suggested` note in the output), not verdicts: the AI judges "can this page be filled, and what gates it" from the census and the screenshot, and may overrule the suggestion. The mechanical rule safe-fill still enforces: it only proceeds on one unambiguous qualifying form. A CAPTCHA page may be staged only when the owner explicitly accepts normal human completion; never bypass or solve it by an external CAPTCHA service. <cmd><![CDATA[ node scripts/inspect-page.mjs --session "inspect-comment-scan" --mode comment \ --url https://example.com/article --out .backlink/scan.json ]]></cmd> Modes are `comment`, `directory`, or `auto`.

The human reviews the rendered page and performs final submission. Only after the user explicitly authorizes one exact reviewed submission may the agent run `release-submit-guard.mjs` — and releasing the guard still does not click Submit. When the owner has explicitly accepted normal CAPTCHA completion, add `--allow-captcha`; this only permits guarded filling and leaves the CAPTCHA and final submission untouched. CAPTCHA routes are always handoff-only. Once the filled form is visibly ready for the owner, release only the guard with `release-submit-guard.mjs --human-handoff`, then stop. The agent must not solve the challenge or click Submit, even when a batch authorization already exists. </fill> <staged-queue> Lane B leaves forms on screen for the owner to finish. **One session name per staged site** — a session owns one tab, so reusing one session overwrites the previous staged form while the report still says N staged. `adapter-phpld.mjs` carries the reference implementation. </staged-queue> </workflow> <workflow id="analyze" when="the user has exported backlink data already"> <statement> Analyze referring-domain quality and topical relevance; suspicious networks, sitewide links, and toxic patterns; anchor and target-page diversity; follow/nofollow/UGC/sponsored distribution **when observed**; competitor gaps and prioritized next opportunities. </statement> <read> <ref file="references/link-quality-rubric.md"/> — scoring, toxicity, disavow. <ref file="references/analysis-templates.md"/> — report shapes. <ref file="references/outreach-templates.md"/> — frameworks; sending needs the user's explicit approval per message. </read> <hard-limit> These templates assume you already have the data.

It documents failures that produce **plausible, silently wrong output**: virtual scroll tables that are not `&lt;table&gt;` and drop rows without erroring, long URLs that make whole rows vanish, execution-channel timeouts that look like failure while the page loop is still running, and Chrome's intensive throttling stretching a four-second loop into twenty-five minutes. </read> <cmd><![CDATA[ sh scripts/harvest-collect.sh # wait for downloads to settle, then collect node scripts/harvest-merge.mjs # merge by field shape, refuse duplicate files ]]></cmd> <note> `scripts/harvest.browser.js` is the in-page collector.

Reach for it only when you need the whole table as a file.

The traffic gate only works if unmeasured rows are excluded from a batch rather than waved through. `--min-traffic` drops them by design; `--unmeasured` lists them as the next screening queue, never as a batch. </rule> <rule id="validate-gates-against-known-bad"> A gate metric is validated against known-bad domains, never against famous ones. Any signal a link network can manufacture for itself — DR, popularity rank, index size — will pass a farm. Tranco's top-1M failed exactly this way: 48 of 73 confirmed farm domains sat inside it, from rank 134k to 998k. </rule> <rule id="no-fabrication"> No generic praise, fake identity, invented metrics, or a comment body that ignores the article it sits under. Never invent a product fact to fill a field — founder, pricing, address, launch date, user count, ownership, legal, contact. Leave optional unknowns blank and stop a row whose required field is unknown. </rule> <rule id="relevance-ranks-never-gates"> A host site on a different topic is fine. Relevance and DR **rank** candidates, they never **gate** them, and `nofollow` is an observation to record rather than a reason to skip. Read <ref file="references/acquisition-doctrine.md"/> before rejecting any target on quality grounds. </rule> <rule id="no-link-farms"> No link farms, spam generators, adult/malware surfaces, hidden reciprocal links, temporary eligibility pages, or cloaking. Two identical give-aways in one place — one site script across dozens of domains, and a promotional sentence repeated word for word — mean one operator. Submitting to N of its domains buys one link's value while accruing N times the footprint. </rule> <rule id="submission-is-not-a-backlink"> Do not record a submission as a backlink. This includes handing a URL to a search engine: that is an index-submission channel, it publishes no link, and it belongs in `data/index-submission.json` rather than the placement ledger. </rule> <rule id="observe-before-recording"> Do not record `follow`, `nofollow`, `ugc`, `sponsored`, or `indexed` without observing it for the exact URL. A click, a completed registration, a saved draft, a form that cleared itself, or a generic thank-you URL is **not** evidence of a submission — those record what you did, and the ledger records what the site did. </rule> <rule id="never-retry-ambiguous"> Do not automatically resubmit an unconfirmed target. Never retry an ambiguous final action — one where the submit happened and the result was not observed. Check the account backend, then the mailbox, then the public page. That state is `outcome-unknown`, and it is not a failure. </rule> <rule id="check-ledger-before-selecting"> Before selecting any batch, read the project's own `.backlink/ledger.json`. A domain already at `submitted` or later (`public`, `indexed`, `rel_verified`) is not selected again — the Skill's target database is shared across every project, so "already submitted" is only ever true per-project, and only the project's ledger knows it. `rejected` domains are skipped by the same default; reopen one only after re-reading its notes and confirming the reason no longer holds, via `--include-rejected`. `scripts/targets-select.mjs` does this automatically from `.backlink/ledger.json` relative to the working directory — running it from inside the project is enough, no flag required. </rule> <rule id="write-back-or-repeat"> A run that ends without writing its results back into the ledger (`ledger.mjs upsert` + `transition`, with evidence for `submitted`/`public`/`indexed`/ `rel_verified`) is a run the next selection cannot see. The domain stays eligible and gets submitted to again. Writing back is part of finishing the batch, not an optional follow-up. </rule> <rule id="fix-data-on-mismatch"> The ledger records what a project did; `data/submission-targets.json` and `data/free-channels.json` record what a channel **is**, and that second layer goes stale the same way the first one does. Every time a real submission shows the recorded gates or fields were wrong — a site the record marks open-form now demands a login, a `captcha` the record calls `none` actually challenges you, a channel the record calls free turns out to gate the useful path behind payment, the route redirects somewhere new, or the site is dead — correcting that record is part of finishing the run, not a follow-up. Fix the field before the batch ends, append the date and what was observed to `notes`, and run `scripts/validate-data.mjs` before you call the run done. A record left wrong is not a neutral gap: the next selection reads it as true and repeats the same mistake against the same site. </rule> <rule id="anchor-policy"> Anchor text is the brand, the product name, or the naked canonical URL. Never request dofollow treatment, never repeat a commercial exact-match anchor across a campaign, and treat a paid or incentivised placement that publishes as a plain follow link as **noncompliant** rather than as a win. </rule> <rule id="secrets"> Records carry aliases and evidence IDs. Passwords, OTPs, recovery codes, cookies, OAuth parameters, magic links, raw session IDs, raw email addresses, and phone numbers belong in none of them. Keep raw cookies, tokens, authorization headers, and credentials out of logs. </rule> <rule id="traffic-figures-need-six-fields"> A third-party traffic figure without `source · metric · month · geography · device · date verified` is not a number. Store all six or store none. </rule> <rule id="http-over-mcp"> Prefer a documented HTTP endpoint over an MCP server when both serve the same data from the same quota — the MCP adds a connection and a process without adding capability, and a failure there is harder to tell apart from the service being down. Keep MCP where it is the only authorized channel; never retire a working path before the replacement has run successfully once. </rule> <rule id="verify-before-trusting-a-row"> Records carry `lastVerifiedAt` because this genre dies faster than it changes. A channel that worked three months ago may be gone, gated, or `noindex` today. Re-verify before a campaign; the validator warns on anything `live` older than 180 days. **Fixing a wrong row is worth more than adding a new channel.** </rule> <rule id="two-tables-two-claims"> `free-channels.json` records **a published link on a live page** and requires `relObserved`/`anchorRendered`. `submission-targets.json` records **a submission route that exists** and the validator rejects those fields there. A target graduates from the second into the first the moment an actual anchor is observed; until then it makes no promise about `rel`, anchor text, or indexability, and the report must not imply one. </rule> <rule id="closed-loop-volume-check"> Two volume sources disagreeing by more than ~3× is not evidence that "volume is unreliable" — it is a resolvable arithmetic question, and you MUST resolve it before either number enters a decision. Pick a domain ranking #1 for the disputed keyword, get its real traffic and Organic-Search share from Similarweb, and get its ranked keywords with volumes from Semrush. Divide observed organic clicks by the candidate volume total to get an implied CTR: under 40% is plausible, over 100% falsifies that volume. This validates **volume only, never intent** — a keyword can clear the CTR check and still be worthless if the SERP shows the searchers do not want what you sell. A falsification of one function of a tool (its volume model) says nothing about another function of the same tool (e.g. SERP-composition reads have no estimation model and are unaffected). Full worked example: <ref file="references/authorized-data-sources.md"/>. </rule> <rule id="volume-durability-check"> A closed-loop volume check validates **magnitude at one point in time**. It says nothing about whether that demand persists, and the two questions need separate evidence. Traffic tools report a trailing window, so a keyword measured during a viral spike passes the CTR check with real, correctly-computed, and already-obsolete numbers. Before a keyword is allowed to anchor a product line, a page build, or a link campaign, pull a multi-year **Google Trends** curve for it alongside a known-evergreen term in the same category. A term that is flat at zero until one month, spikes, and decays is a fad — entering it means fighting for a shrinking pool, and the incumbent's traffic collapse will be invisible in rank data. The diagnostic that separates the two causes: if the incumbent still holds #1 while its traffic falls, **demand fell, not rankings** — that is decay, not a penalty, and no amount of link building recovers it. Real case: a keyword verified closed-loop at 72k–143k/mo went to 2.2/100 on Trends within three months while the #1 site kept its position and lost 87% of its traffic. </rule> </rules> <escalation> <summary>Read the reference **before** acting, not after the run goes wrong.</summary> <when trigger="any browser work at all">references/browser-runtime.md</when> <when trigger="any fill, submit, account, or logged-in action">references/safety-policy.md</when> <when trigger="a supplied list of 100+ rows, or anything that must survive interruption">references/batch-campaign.md — the single-target loop deduplicates too late, stalls behind the first CAPTCHA, cannot tell an interrupted row from an unstarted one, and produces a number that counts forms instead of links</when> <when trigger="about to actually submit to directories — authorization, hidden free tiers, no-fabrication, ledger hygiene">references/directory-run-playbook.md — a real run's difficulty is before and after the form, not in it: 4 of 5 successful submissions hid their free tier behind a paid upsell, one target was already listed without any submission, and a driver's ledger row went stale the moment someone else finished the job</when> <when trigger="a first submission campaign">references/field-notes.md — personal-contact requirements outrank CAPTCHAs, and landing-page CAPTCHA scans give false negatives</when> <when trigger="someone hands you a 'places to get backlinks' list">the "Reading a third-party list" section of references/instant-publish.md — a Dofollow column is an assertion about a platform, never an observation of a link</when> <when trigger="the ask is about paid placement">references/paid-platforms.md</when> <when trigger="the ask is about getting pages into an index rather than getting a link">references/index-submission.md</when> <when trigger="about to reject a target on quality grounds">references/acquisition-doctrine.md</when> <when trigger="BacklinkDirs eligibility">references/backlinkdirs.md</when> <when trigger="the user wants a ready-to-copy prompt">references/prompts.md</when> <when trigger="whose work is this built on">references/credits.md</when> </escalation> <output-contract> <item n="1">data sources and authorization boundary</item> <item n="2">candidates by type, and the reason for qualification or rejection</item> <item n="3">current ledger state, never an inferred later state</item> <item n="4">evidence links or local evidence files</item> <item n="5">the next safe action, and whether human review or submission is required</item> </output-contract> <install> Source: [Skills.sh](https://skills.sh/yan-labs/yan-skills) <cmd><![CDATA[ npx skills add yan-labs/yan-skills --skill opencli -g -y # install this FIRST npx skills add yan-labs/yan-skills --skill backlink -g -y # first install npx skills update backlink -g -y # update ]]></cmd> For a project-level install omit `-g`; update with `npx skills update backlink -p -y`.

opencli comes first. Every browser action in this Skill runs through it, and it carries the rules this Skill only summarises.

It also requires the OpenCLI binary and browser extension from yan-labs/OpenCLI releases — not the Chrome Web Store build. The store build defaults to foreground: it raises a window and steals the tab the person is reading. That failure is silent — commands still succeed, only the behaviour is wrong — so opencli doctor flags an extension older than 1.0.32 explicitly. When it does, act on it rather than working around it. </install>
