Pinboard Manager

Use this skill for ALL Pinboard bookmark management tasks — this is the go-to skill whenever Pinboard (pinboard.in) is involved. Invoke immediately when the user wants to: audit or reorganize messy tags, check for broken/dead links, identify stale or outdated bookmarks, clean up their bookmark collection, or manage their Pinboard account in any way. Also use when the user says 整理书签, 检查死链, 整理 tag, 书签管理, pinboard cleanup, bookmark audit, tag consistency, timeliness check, pinboard 过时检测. Do NOT trigger for: browser bookmark management, Raindrop.io, or general URL checking without Pinboard context.

Interactive Pinboard bookmark management with tag auditing, dead link detection, and content timeliness checking.

Prerequisites

Tool	Type	Required	How to get
Pinboard account	service	Yes	pinboard.in
PINBOARD_AUTH_TOKEN	env var	Yes	See user-config.md
curl	cli	Yes	Built-in on macOS/Linux

Do NOT proactively verify these tools on skill load. If a command fails due to a missing tool or token, directly guide the user through setup step by step.

First-Time Setup

If ~/.config/nini-skill/pinboard-manager/tag-convention.md does not exist, run the Tag Convention Generator before any other mode:

1. Fetch all bookmarks via the Pinboard API
2. Analyze existing tags: frequency, patterns, languages, potential typos
3. Present findings to the user:
   • Top 30 tags by frequency
   • Tags that look like typos or duplicates
   • Chinese/non-English tags that may need English equivalents
   • Tags with inconsistent casing or separators
4. Ask the user about their preferred categories (tech, life, culture, etc.)
5. Generate ~/.config/nini-skill/pinboard-manager/tag-convention.md based on the analysis and user input, following the structure in references/tag-convention.example.md
6. Confirm with the user before saving

An example convention is provided at references/tag-convention.example.md for reference. Users should customize it to match their own bookmarking habits.

Mode Selection

User Intent	Mode	Section

API Helpers

All Pinboard API calls use these patterns:

Fetch bookmarks

bash

# Fetch all bookmarks
curl -s "https://api.pinboard.in/v1/posts/all?auth_token=$PINBOARD_AUTH_TOKEN&format=json"

# Fetch bookmarks with toread=yes
curl -s "https://api.pinboard.in/v1/posts/all?auth_token=$PINBOARD_AUTH_TOKEN&format=json&toread=yes"

# Fetch a specific bookmark by URL
curl -s "https://api.pinboard.in/v1/posts/get?auth_token=$PINBOARD_AUTH_TOKEN&format=json&url=ENCODED_URL"

Update a bookmark (overwrite mode)

CRITICAL: Always pass ALL fields to avoid data loss. The /posts/add endpoint overwrites the entire bookmark.

bash

curl -s "https://api.pinboard.in/v1/posts/add?auth_token=$PINBOARD_AUTH_TOKEN&format=json&url=ENCODED_URL&description=ENCODED_TITLE&extended=ENCODED_NOTES&tags=ENCODED_TAGS&shared=ORIGINAL_SHARED&toread=ORIGINAL_TOREAD&replace=yes"

Required fields to preserve:

• url — the bookmark URL (identifier)
• description — title
• extended — notes/description
• tags — space-separated tag list
• shared — yes or no
• toread — yes or no
• replace — MUST be yes to update existing

Delete a bookmark

bash

curl -s "https://api.pinboard.in/v1/posts/delete?auth_token=$PINBOARD_AUTH_TOKEN&format=json&url=ENCODED_URL"

Rate limiting

Pinboard recommends at most 1 API call per 3 seconds. When making multiple calls (batch updates, link checks), add sleep 3 between calls.

posts/all special limit: This endpoint is rate-limited to once every 5 minutes. Cache the result in /tmp/pinboard_all.json and reuse it within the same session. If both Tag Audit and Dead Link Detection are run consecutively, reuse the cached file.

Tag Audit Mode

Audit bookmarks against the tag convention, present issues in batches, apply fixes with confirmation.

See references/tag-audit.md for the complete 5-step workflow.

Dead Link Detection Mode

Check all bookmarks for broken URLs via HTTP HEAD/GET, report results for user action.

See references/dead-link.md for the complete 5-step workflow.

Timeliness Check Mode

Identify outdated tech bookmarks using heuristic pre-filtering + AI content analysis via Jina Reader. Does NOT auto-delete -- all actions require user confirmation.

See references/timeliness.md for the complete 7-step workflow.

Common Errors

Error	Cause	Fix
PINBOARD_AUTH_TOKEN not set	Env var missing	See user-config.md
403 Forbidden on API calls	Invalid or expired token	Re-check token at Pinboard settings
429 Too Many Requests	Rate limit exceeded	Increase sleep between calls; posts/all is limited to once per 5 min
Partial update lost data	Missing fields in /posts/add	Always pass ALL original fields with replace=yes
Jina Reader empty response	Site blocks Jina Reader or URL is broken	Skip this bookmark, mark as "unable to fetch"
Jina Reader timeout	Slow site or network issue	Skip and continue with next candidate
