When writing internal links, apply the link format from llm-wiki/SKILL.md (Link Format section) using the OBSIDIAN_LINK_FORMAT value.
Step 0: Detect Current Project
Before fetching anything, determine whether the user is working inside a specific project.
Detection order (first match wins):
- Git remote name — run
git remote get-url origin 2>/dev/nullfrom the current working directory. Strip the host, org, and.gitsuffix to get the repo name. Example:https://github.com/acme/my-app.git→my-app.
- Package metadata — if no git remote, check
package.json(namefield),pyproject.toml([project] name),Cargo.toml([package] name),go.mod(module path last segment), in that order.
- Directory name — if none of the above work, use the basename of the current working directory.
- No project context — if the current directory IS the obsidian-wiki repo itself, or if detection produces a name that matches the wiki vault directory, treat it as "no project context" and fall back to
misc/.
Normalise the project name: lowercase, replace spaces and underscores with -, strip leading dots.
Once you have a candidate name, check whether $OBSIDIAN_VAULT_PATH/projects/<project-name>/ exists:
Situation
Action
Project detected + folder exists
Add page to existing project (Step 3a)
Project detected + folder does not exist
Create project structure, then add page (Step 3b)
No project context
Fall back to misc/ (Step 3c)
Step 0.5: Clean Extraction Preflight
Before fetching, check whether the defuddle CLI is available:
which defuddle
- If available: Use
defuddle <url>(via Bash) to retrieve a clean, stripped-down markdown version of the page. This removes ads, navbars, cookie banners, and related-content sidebars — reducing token usage by ~40-60% on typical articles. Use thedefuddleoutput as your content source for Step 4 instead of the raw WebFetch result.
- If not available: Fall back to
WebFetchas normal. No action needed.
Step 1: Fetch the URL
Use WebFetch to retrieve the content at the provided URL (or skip if defuddle was used in Step 0.5).
- If the page is paywalled, JS-rendered (blank body), or returns an error: create a stub page with the title (inferred from the URL), the URL, and
stub: truein frontmatter. Append this to the body:> [Stub] Page could not be fetched — enrich manually.Then skip to Step 6.
- If the page fetches successfully: proceed to Step 2.
Step 2: Check for Duplicate
Before creating a new page, check whether this URL was already ingested:
- Grep
.manifest.jsonfor the URL string in anysource_urlfield
- If in project mode: grep
$OBSIDIAN_VAULT_PATH/projects/<project-name>/for the URL string
- If in misc mode: grep
$OBSIDIAN_VAULT_PATH/misc/for the URL string
If found: report which page covers it and offer to re-ingest (update) if the user wants fresh content. Do not create a duplicate page.
Step 3: Determine Target Path and Generate Slug
Derive a slug from the URL:
- Strip
https://,http://, and trailing slashes
- Take hostname + first 2 meaningful path segments
- Lowercase everything; replace
/,.,?,=,&,#, and spaces with-
- Collapse consecutive
-into one; trim leading/trailing-
- Cap at 50 characters
- Prepend
web-
Examples:
https://martinfowler.com/articles/microservices.html→web-martinfowler-com-articles-microservices
https://arxiv.org/abs/1706.03762→web-arxiv-org-abs-1706-03762
Step 3a: Existing project
Target: $OBSIDIAN_VAULT_PATH/projects/<project-name>/references/<slug>.md
Create references/ inside the project folder if it doesn't exist yet. This is a reference page, not a synthesis or concept page — it documents an external source that's relevant to the project.
Step 3b: New project
First, create the project skeleton:
projects/<project-name>/
├── <project-name>.md ← project overview (stub — fill in what you know)
├── concepts/
├── references/
└── skills/
The project overview stub (<project-name>.md) frontmatter:
---
title: "<Project Name>"
category: project
tags: []
sources: []
created: "<ISO-8601 timestamp>"
updated: "<ISO-8601 timestamp>"
summary: "Project wiki for <project-name>. Created automatically via ingest-url."
---
Then add the page to: projects/<project-name>/references/<slug>.md
Report to the user: "Created new project <project-name> in the vault."
Step 3c: No project context (misc fallback)
Target: $OBSIDIAN_VAULT_PATH/misc/<slug>.md
Create the misc/ directory if it does not exist yet.
Step 4: Extract Knowledge
From the fetched content, identify:
- Title — the page's actual title (from
<title>or# heading)
- Core concepts — what is this page fundamentally about?
- Key claims — the 3-7 most important assertions or findings
- Entities mentioned — people, tools, libraries, organizations
- Related topics — what fields or ideas does this connect to?
- Open questions — what does the page raise but not answer?
Track provenance per claim:
- Extracted — page explicitly states this (no marker needed)
- Inferred — you're generalizing or connecting to external context →
^[inferred]
- Ambiguous — page is vague or internally contradictory →
^[ambiguous]
Step 5: Write the Page
The frontmatter differs slightly between modes:
Project mode (projects/<project-name>/references/<slug>.md):
---
title: "<page title>"
category: references
project: "<project-name>"
tags: [<2-4 domain tags from taxonomy>]
sources:
- "<URL>"
source_url: "<URL>"
created: "<ISO-8601 timestamp>"
updated: "<ISO-8601 timestamp>"
summary: "<1-2 sentence description of what this page is about, ≤200 chars>"
stub: false
provenance:
extracted: 0.X
inferred: 0.X
ambiguous: 0.X
base_confidence: <computed — see below>
lifecycle: draft
lifecycle_changed: "<ISO date today>"
---
Misc mode (misc/<slug>.md):
---
title: "<page title>"
category: misc
tags: [<2-4 domain tags from taxonomy>]
sources:
- "<URL>"
source_url: "<URL>"
created: "<ISO-8601 timestamp>"
updated: "<ISO-8601 timestamp>"
summary: "<1-2 sentence description of what this page is about, ≤200 chars>"
affinity: {}
promotion_status: misc
stub: false
provenance:
extracted: 0.X
inferred: 0.X
ambiguous: 0.X
base_confidence: <computed — see below>
lifecycle: draft
lifecycle_changed: "<ISO date today>"
---
**Computing base_confidence for a URL source:**
Classify the URL's quality bucket using the host:
arxiv.org,doi.org, conference sites →paper(1.0)
*.gov, official vendor docs (e.g.docs.python.org,developer.mozilla.org) →official(0.9)
- Well-maintained third-party docs (e.g.
docs.docker.com) →documentation(0.85)
- GitHub READMEs (
github.com) →repository(0.75)
- Personal blogs, Medium, Substack, dev.to →
blog(0.55)
- Stack Overflow, Hacker News, Reddit →
forum(0.4)
- Anything else →
unknown(0.4)
With 1 distinct source: base_confidence = round(0.17 + 0.5 × quality_score, 2)
Examples: paper → 0.67, official → 0.62, documentation → 0.60, repository → 0.55, blog → 0.45, forum/unknown → 0.37.
Then write the body (same for both modes):
## Overview— 2–4 sentence summary of what the page covers
## Key Points— bulleted list of main claims/findings, with provenance markers
## Concepts— wikilinks to related concept pages ([[concepts/...]]); create minimal stubs for important ones that don't exist yet
## Entities— wikilinks to entity pages ([[entities/...]]) for people, tools, orgs mentioned
## Open Questions— questions the source raises (omit section if none)
## Related— wikilinks to any existing wiki pages this connects to; in project mode, always include a link back to[[projects/<project-name>/<project-name>]]
Apply visibility/internal or visibility/pii tags if the content warrants them. When in doubt, omit.
Minimum wikilinks: every page must link to at least 2 existing pages. Search index.md before writing. If fewer than 2 related pages exist, create minimal stub pages for the most important concepts mentioned.
Step 5b: Affinity scoring (misc mode only)
Skip this step entirely if in project mode.
After writing the page, scan every [[wikilink]] you placed. For each linked page:
- Check if it lives under
projects/<project-name>/
- Check if it has a
project:frontmatter field
- If either is true, increment that project's affinity score
Also: scan the page body for exact mentions of project names listed in index.md. Each unlinked mention adds +1 to that project's score.
Write the result to the affinity frontmatter block. Leave affinity: {} if no project connections found.
If any project's score ≥ 3, surface it:
⚡ Strong affinity detected: this page has 3+ connections to <project-name>. Run the cross-linker skill to recompute affinity and then consider promoting this page to projects/<project-name>/references/.
Step 6: Update Project Overview (project mode only)
Skip this step if in misc mode.
Read the project overview at projects/<project-name>/<project-name>.md. If the overview is a stub or doesn't mention this reference yet, add the new page to a ## References section:
## References
- [[projects/<project-name>/references/<slug>]] — <one-line summary>
If a ## References section already exists, append to it. Update the updated timestamp in frontmatter.
Step 7: Update Manifest and Special Files
**.manifest.json** — add or update the entry:
{
"ingested_at": "TIMESTAMP",
"source_url": "https://...",
"source_type": "url",
"stub": false,
"project": "<project-name or null>",
"promotion_status": "<project-name or misc>",
"pages_created": ["projects/<project-name>/references/<slug>.md"],
"pages_updated": ["projects/<project-name>/<project-name>.md"]
}
Update stats.total_sources_ingested and stats.total_pages.
**index.md** — add the new page under the appropriate section:
- Project mode: under
## Projects > <project-name>
- Misc mode: under
## Misc(create the section at the bottom if it doesn't exist)
**log.md** — append:
Project mode:
- [TIMESTAMP] INGEST_URL url="<url>" page="projects/<project-name>/references/<slug>.md" project="<project-name>" mode=project
Misc mode:
- [TIMESTAMP] INGEST_URL url="<url>" page="misc/<slug>.md" affinity={} promotion_status=misc mode=misc
Step 8: Update hot.md
Read $OBSIDIAN_VAULT_PATH/hot.md (create from the template in wiki-ingest if missing). Update Recent Activity with what was just ingested — keep the last 3 operations. Update Key Takeaways if the page introduced a concept worth flagging. Update updated timestamp.

.manifest.json,index.md, andlog.mdupdated
- Stub pages reported to user if fetch failed
QMD Refresh After Vault Writes
QMD is a search index, not the source of truth. If $QMD_WIKI_COLLECTION is empty or unset, skip this step. Run it only after this skill has written or rewritten vault markdown. If QMD refresh fails, do not roll back the vault changes; report the QMD status separately.
Use $QMD_CLI if set; otherwise use qmd.
${QMD_CLI:-qmd} update
If the output says vectors are needed or embeddings may be stale, run:
${QMD_CLI:-qmd} embed
Verify the collection with either:
${QMD_CLI:-qmd} ls "$QMD_WIKI_COLLECTION"
or, when a specific page path is known:
${QMD_CLI:-qmd} get "qmd://$QMD_WIKI_COLLECTION/<page>.md" -l 5
Record one of:
QMD refreshed: update + embed + verified
QMD refreshed: update only + verified
QMD skipped: QMD_WIKI_COLLECTION unset
QMD skipped: qmd CLI unavailable
QMD failed: <short error summary>
