Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00015 | $0.02004 |
| Opus 5 | $0.00008 | $0.01002 |
| Sonnet 5 | $0.00003 | $0.00401 |
| Haiku 4.5 | $0.00002 | $0.00200 |
Grade A, and why
backlinks scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 217 lines — stays where its author put it; the contents beside it link to each section on GitHub.
mdvdb backlinks
Show files that link TO a specific file. Unlike mdvdb links, which shows both
directions, backlinks focuses on incoming graph connections. A backlink may come from a body
Markdown link, a body wikilink, or a whole-value frontmatter Relation.
Usage
mdvdb backlinks <FILE_PATH> [OPTIONS]
Arguments
| Argument | Required | Description |
|---|---|---|
FILE_PATH |
Yes | Relative path to the markdown file (e.g., docs/readme.md) |
The FILE_PATH must be the relative path as stored in the index (relative to the project root). The file must have been ingested for its backlinks to be available.
Options
This command has no command-specific options. Only global options apply.
Global Options
These options apply to all commands. See Commands Index for details.
| Flag | Short | Description |
|---|---|---|
--verbose |
-v |
Increase log verbosity (-v info, -vv debug, -vvv trace) |
--root |
Project root directory (defaults to current directory) | |
--no-color |
Disable colored output | |
--json |
Output results as JSON |
Human-Readable Output
When run without --json, backlinks displays a formatted list of files linking to the target:
● Backlinks to docs/api/endpoints.md
Incoming: 4 incoming links

│ line 12
├── docs/index.md "Endpoints Reference"
│ line 34
├── docs/api/overview.md "Endpoints" [wikilink]
│ line 8
└── projects/relaunch.md "API Endpoints" (reference)
frontmatter
If no files link to the target:
● Backlinks to docs/orphan-page.md
✗ No files link to docs/orphan-page.md
Output Elements
| Element | Description |
|---|---|
| Source file | The file that contains a link pointing to the target |
| Link text | The display text of the body link or frontmatter Relation (in quotes) |
| Line number | For a body link, the 1-based line where it appears |
frontmatter |
Location shown instead of a line number for a frontmatter Relation |
(field) |
Dimmed badge naming the originating frontmatter Relation field |
[wikilink] |
Blue badge indicating the link uses [[wikilink]] syntax |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
