What it does
Upstream Sync is an agent skill from grandamenium/cortextos. Check for cortextOS framework updates from the remote repo. Fetches changes, categorizes them, explains in plain English, and applies only with user approval.
Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Writing & Content, covering Plain language and style rules. The licence is MIT.
When your agent uses it
- Tasks that involve Plain language and style rules
Example prompts
- “/upstream-sync”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 6f93838. 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
Shell commands in SKILL.md call:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
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
Upstream Sync loads about 501 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 215 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
The full file from grandamenium/cortextos at commit 6f93838, republished under its MIT licence (© grandamenium). 215 words, ~501 tokens.

Upstream Sync
Check for cortextOS framework updates from the remote repository. Never auto-merges. Always explains changes and waits for approval.
When to Run
- Daily cron (configured via
cortextos bus add-cron) - When user asks about updates
- After hearing about new cortextOS features
Workflow
Step 1: Check for updates
RESULT=$(cortextos bus check-upstream)The script fetches from upstream and returns a JSON summary categorizing changes by type (bus scripts, templates, skills, dashboard, etc.).
Step 2: If updates available
- Read the JSON output to understand what changed
- If
catalog_additionsarray is present, note those new community items separately — surface them to user after the framework update conversation - Read the actual diff:
git diff HEAD..upstream/main - Explain EVERY change in plain English to the user via Telegram
- Categorize: security fix, new feature, template change, breaking change
- Recommend: "safe to apply" or "review needed because..."
- Wait for explicit "yes" from the user
Step 3: Apply (only after approval)
cortextos bus check-upstream --applyStep 4: Post-apply
- Verify the merge was clean
- Check if any agent bootstrap files need updating (template changes)
- Report results to orchestrator
Config
Requires ecosystem.upstream_sync.enabled: true in config.json.
Safety
- NEVER auto-merges
- NEVER applies without explicit user approval
- NEVER applies during night mode — check day_mode_start/day_mode_end from config.json before proceeding
- Always explains changes before applying
- Warns about breaking changes or template modifications
