What it does

Upgrade Lightweight Charts Android is an agent skill from tradingview/lightweight-charts-android. Use when upgrading the TradingView lightweight-charts Android wrapper across upstream JavaScript lightweight-charts versions, checking version deltas, API parity, bridge changes, examples, tests, docs, or migration risk.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts (for example `agents/openai.yaml` and `scripts/inspect_versions.py`).

It sits in Mobile. It works with Android, JavaScript and npm. The repository describes itself as: Android wrapper for lightweight-charts library. The licence is Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit d4509df. 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

    Ships 1 file in scripts/ (Python), which the agent can run.

    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

Upgrade Lightweight Charts Android loads about 1.3k tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 597 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~64
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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); the scripts in this folder are not scanned.

Upgrade Lightweight Charts Android

Overview

Use this for end-to-end upgrades of the Android wrapper around upstream JavaScript lightweight-charts. Success requires source-backed API research, scoped implementation, compatibility decisions, and verification evidence—not just a version bump.

When to Use

  • Upgrading lightweightlibrary/package.json to a newer lightweight-charts release.
  • Reviewing wrapper parity after upstream major/minor releases.
  • Planning or changing Kotlin APIs, JS bridge code, serializers, examples, Gradle/WebView assets, docs, or migration notes caused by upstream changes.

Do not use for Android dependency upgrades unrelated to lightweight-charts.

Companion Workflow

  • Use official upstream docs, release notes, package typings, and source checks for upstream API research. If your Codex environment has a source/research skill, it can help, but this skill must remain usable without one.
  • Use a written plan before non-trivial implementation.
  • Use fresh verification evidence before claiming upgrade success.
  • RECOMMENDED: Use code review skills before merge when bridge/API surfaces change.

Workflow

  1. Inspect first. Locate lightweightlibrary/package.json and app/src/main; do not assume a checkout path. Run git status --short --untracked-files=all and protect unrelated user changes.
  2. Discover versions. Run scripts/inspect_versions.py <repo-root> from this skill. Add --npm-latest only when shell network access is available. Verify “latest” live through npm, GitHub releases, and official docs when network state matters.
  3. Inventory deltas. Compare releases from current to target. Audit package typings/source and wrapper surfaces for chart, series, panes, time/price scales, markers, watermarks, localization/formatters, options, events, and generated assets.
  4. Plan non-trivial work. Include target version, release delta, Kotlin API, JS bridge, serialization, examples, tests, docs, compatibility/deprecation choices, unsupported custom/plugin internals, risks, and commands.
  5. Implement in slices. Update package/lock files through the package manager, bridge imports, caches/managers for stable handles, Kotlin interfaces/delegates/models/enums/serializers, examples, docs, tests, and generated assets.
  6. Verify with evidence. Run JS package scripts after bridge changes, Android tests/builds after Kotlin/example changes, and inspect generated WebView assets when asset loading changes.

Migration Checklist

  • Dependency/build/runtime: npm version, lockfile, module format, webpack, Node/WebView compatibility, generated assets.
  • APIs: chart, series, panes, time scale, price scale, event payloads, options, localization, formatter hooks.
  • Built-ins: markers, watermarks, new chart modes, horizontal-scale entry points that do not require custom behavior authoring.
  • Examples, tests, docs, compatibility/deprecation strategy, rollout risks.
Show full SKILL.md (244 more words)Show less

Guardrails

  • Prefer official upstream docs, package typings, and source over secondary summaries.
  • Treat “latest” as unstable; verify it live or state that it could not be checked.
  • Do not hand-wave parity. Search typings and wrapper interfaces, then add focused tests for important claims.
  • Do not replace an existing public Kotlin signature with a narrower/newer type unless a deprecated compatibility overload remains.
  • Preserve existing callback style and wrapper naming unless the migration intentionally breaks API.
  • Bridge source changes require package script runs and generated src/main/assets/.../main.js review.
  • Do not expose generic custom plugins, custom series, or custom primitives unless explicitly scoped.
  • Use portable paths in plans/docs; do not use machine-specific absolute paths.
  • Do not revert unrelated dirty worktree changes.

Validation Scenarios

ScenarioExpected behavior
“Update wrapper to latest lightweight-charts”Verifies latest live, compares local version, inventories upstream deltas, plans before implementation.
“Make v5 panes work”Checks upstream typings/docs and wrapper bridge/Kotlin/example surfaces before coding.
“Replace old API with new v5 type”Preserves source compatibility with deprecated overloads when feasible.
Dirty worktree with unrelated filesLists and avoids unrelated changes.

Common Mistakes

MistakeFix
Bumping npm version onlyInventory release deltas and wrapper parity before declaring success.
Trusting stale local checkoutVerify npm/GitHub/docs live or state that latest could not be checked.
Exposing upstream custom internals by defaultDefer custom plugins/series/primitives unless explicitly scoped.
Forgetting generated assetsRun package scripts and include expected asset diffs.
Breaking Kotlin source compatibilityAdd deprecated compatibility overloads or document intentional breakage.
