What it does
Smart Loader is an agent skill from egorfedorov/claude-context-optimizer. Automatically suggests optimal files to preload based on the user's task description and historical context patterns. Activates when the user starts a new task, mentions reading files, or when session context is being set up.
Its SKILL.md is about 530 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Claude Code plugin that tracks token usage, identifies wasted context, and saves 30-50% on API costs. Heatmaps, ROI reports, budget alerts, efficiency scores, git-aware… The licence is MIT.
When your agent uses it
- Starts a new task
- Mentions reading files
- Session context is being set up
Example prompts
- “/smart-loader”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Check for existing templates matching the task type: Glob
- Check historical patterns for the current directory
- Based on the task description and historical data
What it can do on your machine
Read from SKILL.md and the folder at commit f6f20ee. 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:
node
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
Smart Loader loads about 530 tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 269 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.

Smart Context Loader
When a user starts a new task or asks to work on something, check if there are historical patterns that suggest which files they'll need.
When to Activate
- User describes a new task (bug fix, feature, refactor, review)
- User says "let's work on..." or "I need to fix..."
- Session just started and user is describing what they want to do
- User asks "what files do I need for this?"
How to Use
Check for existing templates matching the task type: Glob
~/.claude-context-optimizer/templates/*.json.Check historical patterns for the current directory:
node ${CLAUDE_PLUGIN_ROOT}/src/tracker.js suggest "$(pwd)"- Based on the task description and historical data:
- If a matching template exists, mention it: "I see you have a '{name}' template. Want me to load that context?"
- If historical patterns suggest files, mention: "Based on previous sessions, you usually need these files for this type of task: ..."
- If patterns show files to avoid, mention: "Tip: [file] has been consistently unused in past sessions — I'll skip it."
- If nothing matches, proceed normally
Auto-Optimization Tips
When you detect patterns that waste tokens, proactively suggest improvements:
- If a large file (300+ lines) is being read fully: "I'll use offset/limit to read only the relevant section"
- If a file was wasted in 2+ past sessions: skip it silently or mention why
- If the user's task matches a known template: offer to apply it
Important
- Do NOT automatically read files without user confirmation
- Only SUGGEST, don't force context loading
- Keep suggestions brief (top 3-5 files max)
- If no tracking data exists yet, skip silently — don't mention the optimizer
- Be helpful, not annoying — max 1 suggestion per task start

Can I use Smart Loader in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add egorfedorov/claude-context-optimizer --skill smart-loader -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/smart-loader, .gemini/skills/smart-loader, .github/skills/smart-loader and .opencode/skills/smart-loader in your project.
What does Smart Loader need to run?
Going by SKILL.md and its folder, Smart Loader needs the command-line tools its instructions call (node).
Does Smart Loader access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
