What it is
Reproduce a chart from a screenshot, read your pasted image, diff against the live chart, then set symbol/indicators/drawings to match.
A skill is a written procedure a bot loads when a job calls for it. This one is a single file, SKILL.md, and the whole file is on this page.
The whole file, exactly as it downloads. Read it before you rely on it.

You are recreating a chart layout from a user-provided screenshot using vision + MCP tools.
The user pastes an image. Visually read it and extract:
Symbol — from the top-left ticker label
Timeframe — from the resolution selector (e.g., "5", "15", "1H", "D")

Nothing. It ships with Murage, which is open source. Your bots run on the AI plan you already have.
Yes. Open it in Settings → Skills to read, edit or duplicate it. Skill Guard scans it again after every edit.
Download the app, connect the AI you already pay for, and tell your Chief of Staff what needs doing. Plan on about ten minutes from install to a working team.

Paste it into your agent's instructions (CLAUDE.md, AGENTS.md or a custom GPT), or add it to a bot in Murage.
Ask Ember for the bot, then switch the skill on in its settings.
Step 1
Send your Chief of Staff this message. It proposes the bot and its role first, and creates it when you say go.
Send this to Ember
“Create a bot that uses the Rebuild From Screenshot skill, and show me the plan first.”
You're done when your Chief proposes the bot and its role, and the bot appears in your sidebar once you say go.
Step 2
You're done when you see the bot’s skills and the library.
Step 3
You're done when the skill shows as on for that bot.
Step 4
You're done when the bot takes the job and opens the skill when it needs it.

What it teaches a bot, what it covers, and the whole file to read.
The principle
You are recreating a chart layout from a user-provided screenshot using vision + MCP tools.
What it covers
Step 1: Receive the Screenshot
Step 2: Capture Live Chart State
Step 3: Diff
Step 4: Apply Changes
Step 5: Verify
Step 6: Report
Error Notes
Chart type — Candles, Heikin Ashi, Line, Bars, etc.
Indicators — every pane + overlay study (names + approximate params like "EMA(200)")
Drawings — trend lines, rectangles, horizontal levels, text
Visible date range — leftmost to rightmost bar dates
chart_vision_read — returns combined image + readings (symbol, timeframe, indicator list, key values) in one call. Prefer this over separate capture_screenshot + chart_get_state for this workflow.
If chart_vision_read fails with CHART_LOADING, wait and retry once.
Compare the pasted screenshot against the chart_vision_read output. Build a minimal change list:
Symbol match? If not, queue chart_set_symbol
Timeframe match? If not, queue chart_set_timeframe
Indicator set — which to add, which to remove, which to reconfigure
Drawings — which to add (source coords from the screenshot), which to clear
Execute in this order to minimize reflows:
chart_set_symbol (e.g., "NASDAQ:TSLA")
chart_set_timeframe (e.g., "60")
chart_set_type if needed (e.g., "HeikinAshi")
For each missing indicator: chart_manage_indicator with action "add" and the full name ("Moving Average Exponential", not "EMA")
indicator_set_inputs to match params (e.g., EMA length 200)
For each drawing:
Horizontal level → draw_shape with horizontal_line at the price from the screenshot
Trend line → draw_shape with trend_line + two {time, price} points
Text → draw_shape with text
If leftover studies/drawings don't belong: chart_manage_indicator remove + draw_remove_one by id
Concrete example — rebuilding a TSLA 1H chart with EMA(20)/EMA(200) and a horizontal at 250.00:
chart_set_symbol("NASDAQ:TSLA")
chart_set_timeframe("60")
chart_manage_indicator({ action: "add", name: "Moving Average Exponential" })
indicator_set_inputs({ length: 20 })
chart_manage_indicator({ action: "add", name: "Moving Average Exponential" })
indicator_set_inputs({ length: 200 })
draw_shape({ type: "horizontal_line", point: { price: 250.00 } })chart_vision_read again — confirm the new live state
Diff once more against the user's screenshot
If mismatches remain (e.g., indicator param still off), iterate on step 4
Tell the user what was applied, what couldn't be matched exactly (e.g., proprietary indicators not recognizable by name), and show the final screenshot path.
CHART_LOADING — chart still rendering; wait 1-2s and retry
INDICATOR_NOT_FOUND — name in screenshot isn't a built-in (likely custom Pine); ask user to load it manually
If colors/styles matter for the match, mention them but don't chase perfection — focus on structural fidelity
