At a glance
Builds and checks clickable deep links that open a thread, file, folder or settings panel in tools like Codex, Cursor and VS Code, usually for sharing in Slack.
- Works in 5 steps: Identify target app + target object → Read references/deep-link-matrix.md for… → If support is unknown, verify locally… → …
- Sharing a clickable link to a Cursor or VS Code file in Slack
- SKILL.md covers Overview, Workflow, Output Rules and Common Templates
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Given a target app and object, such as a conversation thread, a file or folder, or a settings panel, the skill picks the right link shape by reading a bundled cross-app matrix of known-good formats and their support level. When support is unknown it verifies locally first, checking the app bundle's declared URL schemes and smoke-testing the scheme with the operating system's open command before sending anything.
Output follows a few fixed rules: build Slack-safe link syntax, prefer absolute paths for file and folder links, keep labels short and action oriented such as Open in Cursor, and never claim a deep link works unless the matrix confirms it or it was just verified. An uncertain route is marked as inferred rather than stated as fact, and templates are given for a Codex thread link and file links into Cursor, VS Code and VS Code Insiders with a line and column.
When your agent uses it
- Sharing a clickable link to a Cursor or VS Code file in Slack
- Checking whether a tool supports a custom URL scheme before linking to it
- Building a fallback message when no deep-link format is known for an app
Example prompts
- “Give me a Slack link that opens this file at line 42 in Cursor.”
- “Does VS Code Insiders support a deep link to a specific line, and how is it formatted?”
- “Build a deep link to this Codex thread for our Slack channel.”
Requirements
- macOS for checking an installed app's registered URL schemes
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Identify target app + target object
- Read references/deep-link-matrix.md for known-good link formats and support level.
- If support is unknown, verify locally before sending
- Construct Slack-safe link syntax
- If unsupported or uncertain, send a fallback
What it can do on your machine
Read from SKILL.md and the folder at commit 0930e13. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Agent Deep Links loads about 513 tokens when it runs, and up to ~1.2k if it reads all its reference files. Until then it costs about 59 tokens; SKILL.md has 207 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 207 words (~513 tokens).
“Use this skill when a user asks for clickable links that should open directly in an app (usually from Slack). This includes verifying whether a target app supports deep links at all, selecting the right URL shape, and providing fallbacks…”
