product-manual-finder

description

Find the official instruction manual/PDF for a specific owned product (by model number or photo), verify it's actually the right document (not a spec sheet or the wrong model), make sure it has a searchable text layer (OCR if it's scan-only), save it into the wiki's assets folder, and synthesize a product page that links and summarizes it. TRIGGER when the user asks to find/gather/look up a manual, instructions, or documentation for a specific tool or appliance they own, or asks how to operate/troubleshoot/reload/reset something and no manual is on file yet.

What This Skill Does

Given a product (photo, model number, or name), this skill:

1. Pins down the exact model number — from the item itself, not a guess
2. Searches manufacturer, retailer-mirror, and aggregator sources for the real instruction manual — not a spec sheet, not a similar model
3. Fetches it through the site's actual access path, working around bot-gating (WebFetch → MCP crawler → Chrome MCP)
4. Verifies the PDF is (a) actually the claimed model and (b) actually an instructions document, not a marketing page
5. Ensures it has an OCR text layer so it's searchable in a PDF viewer and in Logseq's own PDF annotation view
6. Saves it to logseq/assets/ and synthesizes a product page per logseq-wiki-syntax that links it and pulls out the parts someone will actually come back for (loading, resets, part numbers, troubleshooting table)
7. States plainly when no manual exists rather than substituting a spec sheet or a different model's manual and calling it close enough

This skill produces one artifact type — a manual, verified and stored — as part of the wider knowledge-synthesis Recall → Refine → Research → Link loop this wiki runs on. It doesn't replace that loop; it fills in the "find and validate a primary source document" step within it.

Phase 0 — Identify the Exact Product

Entry gate: a photo, model number, or product name from the user.

The single most common way this goes wrong is attaching the right brand's wrong model's manual. Do not skip this phase to save time.

• If given a photo: zoom into the model/serial sticker (crop + resize with magick/convert, see Bash — a 3-4x crop on the sticker region is usually enough to read a blurry label). Cross-check the model number against ≥2 independent sources (official product page + one retailer listing) before treating it as confirmed — model numbers get OCR'd wrong on blurry photos more often than you'd expect.
• If given a model number directly: still confirm it resolves to a real, specific product (not a family/series name) via one search before proceeding.
• Note the manufacturer and the product category (power tool, appliance, furniture, electronics) — this determines which source tier in Phase 1 is likely to pay off first.

Exit gate: exact model number confirmed against ≥2 sources, manufacturer identified.

Phase 1 — Source Tiers (search in this order)

Check brands/<manufacturer-slug>.md first. If a brand reference file exists for this manufacturer, it already documents the verified URL patterns, which domains are bot-gated, and which are dead ends — follow it instead of rediscovering the same things from scratch. See "Brand References" below for the current list and the template for adding a new one.

Stop as soon as a tier produces a verified match (Phase 3) — don't burn searches on lower tiers once a higher one succeeds.

1. Manufacturer's own manuals/support page — best when reachable. Often JS-rendered and/or Cloudflare-gated (see Phase 2 fetch hierarchy). Search: site:<manufacturer>.com "<model>" manual OR "instruction sheet" filetype:pdf
2. Direct manufacturer PDF via general search — "<model>" filetype:pdf manual site:<manufacturer>.com
3. Retailer-mirrored manufacturer PDFs — retailers frequently host the same PDF the manufacturer publishes, on infrastructure that isn't bot-gated. Worth trying even before aggregators:
   • pdf.lowes.com/productdocuments/...
   • Home Depot / Amazon product-detail "user manual" attachments
   • Distributor CDNs (e.g. rexel-cdn.com) — caveat: these sometimes turn out to be a browser print-to-PDF of the product page, not the instruction manual. Looks identical to a real manual in search results. Phase 3 catches this — it has real text, but it won't read like step-by-step instructions or contain a parts diagram.
4. Aggregator manual sites — ManualsLib, Manua.ls, Manuals.plus, iFixit. Lowest trust tier — a missing model here is not proof no manual exists (catalogs are incomplete), but a hit still needs Phase 3 verification like everything else. Several of these (manuals.plus, and often support.<brand>.com) sit behind a Cloudflare JS challenge that blocks both WebFetch and headless MCP browsers — see Phase 2.
5. No manual found — after checking tiers 1-4, say so explicitly on the wiki page (Phase 5) with what was checked and the date. This is a legitimate, expected outcome for simple/unpowered tools (hand staplers, hammer tackers, basic hand tools often ship with only a printed insert, never a published PDF) — do not force a spec sheet or a different model's manual into that gap.

---

Phase 2 — Fetch Tool Hierarchy

Same discipline as product-selection's Phase 3 — try in order, don't give up after one failure. Don't hardcode specific MCP tool names — the exact servers connected vary by project/session (this wiki's session has stapler-mcp; another project might have read-website-fast, a different crawler, or none at all). Instead, escalate by role, and at each rung use ToolSearch to discover what's actually available and pick the best match by reading its description rather than assuming a name:

1. WebFetch — try first; no discovery needed, it's always available.
2. A readability-extraction MCP crawler — reach for this on 403/429 or a JS-rendered page. Run ToolSearch with a query like "read website" / "fetch url" / "crawl" and compare the returned tools' descriptions — look for one that converts a page to clean markdown/text and (ideally) can follow same-host links via a depth/page-count param, useful for crawling a manuals index page to find the right model's link. In this session that's mcp__stapler-mcp__read_website; treat the name as an example, not a requirement — search fresh each time you're in an unfamiliar project.
3. A headless-browser-render MCP tool — use when the previous rung returns empty text on a page that clearly has content (client-side rendered). Same discovery approach: ToolSearch for "render page" / "headless browser" / "fetch page" and pick by description. In this session that's mcp__stapler-mcp__fetch_page.
4. Chrome MCP (navigate + get_page_text, real logged-in browser) — last resort for a Cloudflare JS challenge or login wall that blocks both of the above. ToolSearch for "select:mcp__claude-in-chrome__tabs_context_mcp,mcp__claude-in-chrome__navigate,mcp__claude-in-chrome__get_page_text" (load the whole batch in one call, not one at a time). If Chrome MCP itself isn't connected in this session, say so and stop trying rather than looping on the same failure — don't fabricate a result to fill the gap.

Once you've found the right tool for a given project, it's fine to keep using it for the rest of that session — the point is not re-searching every call, it's not assuming a name before checking once.

Downloading the PDF itself: once you have a direct PDF URL, fetch it (WebFetch will save binary content; or curl/Bash if the URL is plain and un-gated). Confirm it's actually a PDF (file <path> or pdfinfo <path>) before treating the download as successful — a Cloudflare challenge page saved with a .pdf extension will fail pdfinfo immediately, which is a fast, cheap check worth running every time.

Phase 3 — Verify It's the Right Document

Entry gate: a PDF has been downloaded.

Two independent checks — both matter, neither substitutes for the other:

3a. Right model?

Run scripts/verify_manual_pdf.sh <pdf> <model_number>. It extracts text and greps for the model number. MATCH → proceed. NO MATCH → one of two things is true, and you must determine which before proceeding:

• The PDF has no text layer yet (scan-only) → run Phase 4 first, then re-verify.
• The PDF genuinely isn't for this model → discard it, don't cite it.

If still uncertain after OCR, fall back to visually confirming via the Read tool directly on the PDF (Claude Code can read PDF pages as images) — check the cover page or first diagram page for the model number printed on the product itself.

3b. Actually a manual, not a marketing page?

A hit that passes 3a can still be the wrong kind of document — a printed product page, a spec sheet, or a warranty card can all contain the model number without containing a single instruction. Skim the extracted text (or the first few pages via Read) for manual-shaped content: numbered steps, a parts diagram, a troubleshooting table, safety warnings. If it reads like ad copy ("features", "buy now", star ratings) rather than instructions, it is not the manual — keep searching, or fall through to the Phase 1.5 "no manual found" outcome.

Exit gate: PDF passes both 3a and 3b, or the search has been declared exhausted per Phase 1's tier list.

---

Phase 4 — Ensure a Searchable Text Layer

Entry gate: PDF passed Phase 3 (or is pending re-verification after OCR).

1. Run scripts/check_pdf_searchable.sh <pdf>. SEARCHABLE → skip to Phase 5. IMAGE_ONLY → continue.
2. Run scripts/make_searchable.sh <pdf> to add an OCR text layer via ocrmypdf (skips pages that already have text, so it's safe on mixed scan+typeset manuals). If ocrmypdf isn't installed, install it first — brew install ocrmypdf (it pulls in tesseract; check which tesseract first since it's often already present).
3. Re-run check_pdf_searchable.sh to confirm the OCR pass worked, then re-run verify_manual_pdf.sh if Phase 3a was previously blocked by missing text.

Exit gate: check_pdf_searchable.sh reports SEARCHABLE.

---

Phase 5 — Save and Synthesize

Entry gate: PDF verified (Phase 3) and searchable (Phase 4).

1. Save the PDF to logseq/assets/ with a descriptive kebab-case filename: <brand>-<model>-manual.pdf (e.g. dewalt-dwht75900-manual.pdf) — never the retailer's opaque download filename.
2. Create or update the product's wiki page per logseq-wiki-syntax (Zettelkasten style; check for an existing page first per the wiki's Recall-first rule — this skill commonly runs right after a page like the ones in DeWalt DWHT75900 Hammer Tacker.md already exists from an earlier troubleshooting session).
   • Link the manual: [Manual (PDF)](../assets/<filename>.pdf)
   • Don't just link it — synthesize: pull the specific sections someone will actually search the page for later — load/reload procedure, reset sequence, safety warnings, replacement part numbers, troubleshooting table — into the page body itself, citing the manual page number where useful (p. 12).
   • Note the manual's source URL and the date it was fetched, so staleness is checkable later.
3. If no manual was found (Phase 1's fallback): say so explicitly on the page — what was checked, when — and link whatever authoritative source does exist instead (official product page, retailer listing). Never leave this ambiguous or silently omit the manual section.

Exit gate: wiki page exists, links the verified+searchable PDF (or explicitly documents that none exists), and includes synthesized content beyond a bare link.

Brand References

Per-manufacturer notes live in brands/<slug>.md — the actual PDF-hosting URL pattern (when there is one), which support/aggregator domains are bot-gated vs. reachable, which are dead links despite the manufacturer's own docs pointing at them, and manufacturer-specific model/type-number quirks. These exist because rediscovering "is support.acme.com Cloudflare-gated" from scratch every time is exactly the kind of repeated work this skill should eliminate.

Brand	File	Key pattern
DeWalt	brands/dewalt.md	Manuals live on an unblocked Akamai CDN (assets.dewalt.com/GLOBALBOM/...), discoverable only via the product page's "Downloads and manuals" section — not guessable from the model number alone

Adding a new brand: once you've done the Phase 1/2/3 legwork for a manufacturer you expect to see again (the user owns several of their tools, or the pattern took real digging to find), write it up as brands/<slug>.md using brands/dewalt.md's structure as the template:

• Tier 1: the real PDF-hosting pattern, if one exists — URL template, what's guessable vs. not, ≥2 verified working examples (HEAD-check them, don't just cite search snippets)
• Tier 2: how to discover Tier 1's URLs (usually: fetch the product page, ask specifically for the downloads/documents section by name)
• Tier 3: retailer mirrors worth trying
• Tier 4: sources to explicitly avoid (dead links, Cloudflare-gated support portals) and why
• Tier 5: aggregator coverage notes
• Model/type-number quirks specific to that brand's labeling
• Query templates

Don't write a brand file after a single lookup — the value is in patterns confirmed across ≥2 products from that brand (as dewalt.md did with DWS780 and DCS356B) so the "pattern" claim isn't just one lucky hit. A single one-off lookup doesn't need a file; note anything useful for that model directly on its wiki page instead. Add the new brand to the table above.

Bundled Scripts

Script	Purpose
scripts/check_pdf_searchable.sh <pdf>	Reports SEARCHABLE / IMAGE_ONLY by sampling extracted text from the first 3 pages
scripts/make_searchable.sh <pdf> [out]	Adds an OCR text layer via ocrmypdf --skip-text; installs guidance if ocrmypdf is missing
scripts/verify_manual_pdf.sh <pdf> <model>	Confirms the model number appears in the extracted text — the model-mismatch gate

All three are thin wrappers over pdftotext/pdffonts/ocrmypdf (poppler-utils; pdftotext/pdfinfo/pdffonts are already present on this machine). No Python — this is exactly the kind of job three CLI tools already solve; don't add a dependency to wrap them.

Known Failure Modes

Failure	Cause	Fix
Manufacturer product page 404s	SKU delisted/discontinued	Fall back to retailer listings (Home Depot, Amazon) for confirmation; note the 404 and date on the wiki page
support.<brand>.com returns "Just a moment..." / security check	Cloudflare JS challenge blocks WebFetch and headless MCP browsers alike	Try Chrome MCP (real browser); if unavailable, note the source as unreachable rather than fabricating
manuals.plus (and similar aggregators) return 403 on every fetch tool	Cloudflare bot protection	Same as above — Chrome MCP or mark unreachable
A distributor-CDN PDF has real, extractable text but reads like ad copy	It's a browser print-to-PDF of the product page, not the instructions — happens more than expected on CDN-hosted "spec sheet" links	Phase 3b catches this — check for step/diagram content, not just presence of text
verify_manual_pdf.sh reports NO MATCH on a PDF you can see the model number in	grep -q piped directly from pdftotext under set -o pipefail SIGPIPEs the producer and corrupts the pipeline's exit code even on a real match	Already fixed in this skill's script (extracts to a variable first) — if you hand-roll a similar check elsewhere, avoid `producer
Aggregator catalog (e.g. Manua.ls) doesn't list the model	Catalog incompleteness, not proof the manual doesn't exist	Treat as one negative data point among several tiers, not a final answer
Simple unpowered tool (hand stapler, hammer tacker) has no manual anywhere	Many ship with only a printed insert, never a published PDF	Document that explicitly (Phase 5.3) — this is a correct, expected outcome, not a failed search
