Visual Studio Code is a code editor that supports editing, navigating, understanding, debugging, and extending software projects. Developers use it for the edit-build-debug cycle, and the catalogue add-ons provide skills, instructions, and agents for working within the editor.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

What it costs to keep this loaded
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 5.1 | $0.00045 | $0.00283 |
| Opus 5 | $0.00023 | $0.00142 |
| Sonnet 5 | $0.00009 | $0.00057 |
| Haiku 4.5 | $0.00005 | $0.00028 |
Grade A, and why
sync-upstream 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 3d 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.
What it actually says
Update Branch
Rebase the current session branch onto the latest upstream so the work stays grounded in origin.
Workflow
- If there are uncommitted changes, use the
/commitskill to commit them first. - Fetch the latest upstream and rebase onto it:
Use the appropriate base branch if it is notgit fetch origin git rebase origin/mainmain.
Conflict Resolution
When conflicts arise, upstream always wins:
- Never alter upstream logic, APIs, or patterns to accommodate session changes.
- Adapt session work to fit the new upstream — rename, restructure, or rewrite as needed while preserving the session's goals.
- After resolving each conflict,
git addthe files andgit rebase --continue.
Validation
After the rebase completes, verify the result still compiles and meets the session's objectives. If session changes no longer make sense against the updated upstream, explain what changed and propose a revised approach.
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.

sync-upstream is a skill published in the GitHub repository microsoft/vscode (191,195 stars, last pushed today), licensed MIT. It adds 45 tokens to every session and 283 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
Other skills, from other repositories
merge-seed
Merge upstream React Starter Kit updates (the seed remote) into main, preserving this project's identity, scope, and behavior. Use when asked to sync, pull, or merge the seed / starter kit / upstream template.
om-auto-implement-spec
Everything tracker-facing uses the operations and guards from .ai/trackers/github.md. Resolve an automatic base branch through default-branch; never assume main or develop.
cyrene-work-hygiene
A Work-mode rulebook for organizing projects that create, arrange, or deliver several files.
cyrene-obsidian-workspace
A set of rules for an agent working with an Obsidian vault, a folder of linked Markdown notes. It defines where materials, notes, exercises, templates, and progress files belong and how they may be edited.
release-version
Steps to cut a VNote version release (e.g. v4.3.0) — bump the version with scripts/updateversion.py, refresh and fill zhCN/ja translations via lupdate, write the changes.md changelog, and trigger the CI [Release] build. Use when asked to "release", "cut a release", "bump the version", or "prepare vX.Y.Z".
maestro-improve
Turn filed lessons into the smallest doctrine edit. Use when a Lead assigns improvement work for one target: group pending lessons, make one evidence-linked commit per target, return it for independent challenge, and process each accepted or rejected lesson without deleting history.
