# Send Go to your agent Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually. ## Fast path - Download the package from Yavira. - Extract it into a folder your agent can access. - Paste one of the prompts below and point your agent at the extracted folder. ## Suggested prompts ### New install ```text I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete. ``` ### Upgrade existing ```text I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run. ``` ## Machine-readable fields ```json { "schemaVersion": "1.0", "item": { "slug": "go", "name": "Go", "source": "tencent", "type": "skill", "category": "开发工具", "sourceUrl": "https://clawhub.ai/ivangdavila/go", "canonicalUrl": "https://clawhub.ai/ivangdavila/go", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/go", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=go", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "SKILL.md", "collections.md", "concurrency.md", "errors.md", "interfaces.md" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "slug": "go", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-05-03T19:28:41.977Z", "expiresAt": "2026-05-10T19:28:41.977Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=go", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=go", "contentDisposition": "attachment;

var i interface{} = p; i != nil is true Type assertion on wrong type panics—use comma-ok: v, ok := i.(Type) Empty interface any accepts anything but loses type safety—avoid when possible Interface satisfaction is implicit—no compile error if method signature drifts Pointer receiver doesn't satisfy interface for value type—only *T has the method ### Error Handling Errors are values, not exceptions—always check returned error err != nil after every call—unchecked errors are silent bugs errors.Is for wrapped errors—== doesn't work with fmt.Errorf("%w", err) Sentinel errors should be var ErrFoo = errors.New() not recreated Panic for programmer errors only—return error for runtime failures ### Slice Traps Slice is reference to array—modifying slice modifies original Append may or may not reallocate—never assume capacity Slicing doesn't copy—a[1:3] shares memory with a Nil slice and empty slice differ—var s []int vs s := []int{} copy() copies min of lengths—doesn't extend destination ### Map Traps Reading from nil map returns zero value—writing to nil map panics Map iteration order is random—don't rely on order Maps not safe for concurrent access—use sync.Map or mutex Taking address of map element forbidden—&m[key] doesn't compile Delete from map during iteration is safe—but add may cause issues ### String Traps Strings are immutable byte slices—each modification creates new allocation range over string iterates runes, not bytes—index jumps for multi-byte chars len(s) is bytes, not characters—use utf8.RuneCountInString() String comparison is byte-wise—not Unicode normalized Substring shares memory with original—large string keeps memory alive ### Struct and Memory Struct fields padded for alignment—field order affects memory size Zero value is valid—var wg sync.WaitGroup works, no constructor needed Copying struct with mutex copies unlocked mutex—always pass pointer Embedding is not inheritance—promoted methods can be shadowed Exported fields start uppercase—lowercase fields invisible outside package ### Build Traps go build caches aggressively—use -a flag to force rebuild Unused imports fail compilation—use _ import for side effects only init() runs before main, order by dependency—not file order go:embed paths relative to source file—not working directory Cross-compile: GOOS=linux GOARCH=amd64 go build—easy but test on target ## Trust - Source: tencent - Verification: Indexed source record - Publisher: ivangdavila - Version: 1.0.2 ## Source health - Status: healthy - Item download looks usable. - Yavira can redirect you to the upstream package for this item. - Health scope: item - Reason: direct_download_ok - Checked at: 2026-05-03T19:28:41.977Z - Expires at: 2026-05-10T19:28:41.977Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/go) - [Send to Agent page](https://openagent3.xyz/skills/go/agent) - [JSON manifest](https://openagent3.xyz/skills/go/agent.json) - [Markdown brief](https://openagent3.xyz/skills/go/agent.md) - [Download page](https://openagent3.xyz/downloads/go)
