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 | $0.00041 | $0.00306 |
| Opus 5 | $0.00020 | $0.00153 |
| Sonnet 5 | $0.00008 | $0.00061 |
| Haiku 4.5 | $0.00004 | $0.00031 |
Grade A, and why
ctx-upgrade scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Context Mode Upgrade
Pull latest from GitHub and reinstall the plugin.
Instructions
- Call the
ctx_upgradeMCP tool directly. It returns a shell command to execute. - Run the returned command using your shell execution tool (Bash, shell_execute, etc.).
- Display results as a markdown checklist:
Use## context-mode upgrade - [x] Pulled latest from GitHub - [x] Built and installed v1.0.39 - [x] Hooks configured - [x] Doctor: all checks PASS[x]for success,[ ]for failure. Show actual version numbers. - Tell the user to restart their session to pick up the new version.
- Fallback (only if MCP tool call fails): Derive the plugin root from this skill's base directory (go up 2 levels, remove
/skills/ctx-upgrade), then run with Bash:CLI="<PLUGIN_ROOT>/cli.bundle.mjs"; [ ! -f "$CLI" ] && CLI="<PLUGIN_ROOT>/build/cli.js"; node "$CLI" upgrade
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.

ctx-upgrade is a skill published in the GitHub repository opencue/cuecards (5 stars, last pushed yesterday), licensed MIT. It adds 41 tokens to every session and 306 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 2026-08-31.

rulesync
Generates and syncs AI rule configuration files (.cursorrules, CLAUDE.md, copilot-instructions.md) across 20+ coding tools from a single source. Use when syncing AI rules, running rulesync commands, importing or generating rule files, or managing shared AI coding configurations.
