ACKit Toolkit for VS Code

Offline-first agent readiness for your repository — directly inside VS Code.

• Publisher: Cynrath (Cynrath.ackit-vscode)
• Version: 0.2.2
• Engine: VS Code ^1.90.0
• Activation: onStartupFinished (debounced, lazy refresh)
• Category: Linters
• Offline: No network, no telemetry, no remote fonts — all analysis via shared ACKit SDK

Views (Activity Bar → ACKit)

All views are backed by the shared deterministic SDK (scanRepository, scoreRepository, buildInstructionGraph, analyzeOptimize, etc.), not shell-outs. Data is cached per workspace root and refreshed debounced on file create/change/delete.

• Readiness (ackit.readiness) — Overall 88/100 + 6 categories (Instructions, Security, Context Efficiency, Tasks, Skills, Policy) with weighted renormalization, N/A handling, and expandable deductions. Uses real scoreRepository inputs, tooltip evidence, refresh on change.
• Findings (ackit.findings) — Grouped by severity (critical/high/medium/low), rule ID, path, message. Click to open file at exact line/column. Uses real scanRepository findings.
• Instruction Graph (ackit.graph) — Nodes instr:codex:AGENTS.md, instr:claude:CLAUDE.md, etc., with provider, precedence, provenance, shadowing. Uses buildInstructionGraph + resolveEffectiveStack.
• Tasks (ackit.tasks) — Tasks/policy/optimize summaries (see Diagnostics for details). If you prefer commands only, use ACKit: Diagnostics.
• Policy (ackit.policy) — Policy chain/digest (see Diagnostics).
• Optimize (ackit.optimize) — 8-class taxonomy, severity, token-waste estimates, evidence paths, remediation. Via analyzeOptimize (SDK), preview diff, no silent writes.

Problems Integration

Findings are mirrored to VS Code Problems (ACKITxxx) with correct severity mapping:

• critical/high → Error
• medium → Warning
• low → Information
• info → Hint

Safe path handling via vscode.Uri.joinPath + isInsideRoot check, invalid line/column clamped to 0, repository-level findings skipped gracefully, DiagnosticCollection cleared atomically on refresh.

Commands

• ACKit: Refresh — Refresh all workspaces (debounced, cancellable)
• ACKit: Show Readiness — QuickPick categories
• ACKit: Show Graph — QuickPick nodes or open file
• ACKit: Instructions for Current File — Uses active editor, workspace.getWorkspaceFolder, buildInstructionGraph + resolveEffectiveStack (provider codex), shows ordered effective stack with why + provenance, handles not-in-workspace gracefully
• ACKit: Optimize — Real analyzeOptimize via SDK, QuickPick with severity/category/waste, detail view with Remediation + Preview Diff (no silent writes, respects fixable + dryRun)
• ACKit: Diagnostics — Real loadAckitConfig + TaskStore + policy summary as JSON (config health, tasks, policy, no auto-upload)

All commands support multi-root: getRootForActiveEditor() → active editor's folder, else first workspace, getRoots() for all, watcher per root, refresh per root.

Watch & Activation

• Watcher: onDidCreate + onDidChange + onDidDelete (one debounced 400ms coalesced refresh, AbortController cancels in-flight)
• Ignores: .git, node_modules, dist, .ackit, coverage, artifacts (via walk limits)
• Activation: onStartupFinished (non-blocking, setTimeout(refreshAll, 800)), lazy first access also works (onView/onCommand would also be valid; current keeps startup light)

Multi-Root

• getRoots() → all workspaceFolders
• getRootForActiveEditor() → workspace.getWorkspaceFolder(activeEditor.document.uri) else first root
• service.onDidChange per root, vsce tests cover workspaceFolders?.[0] anti-pattern

Offline-First Guarantee

• No fetch remote, no http/https client, no telemetry SDK, no remote fonts/scripts, no external upload — verified via scripts/check-offline-egress.mjs (includes extensions/vscode/src/**) and tests/contract/vscode-icon.test.ts + offline-egress contract
• VS Code host's own Microsoft networking is not ACKit code (host behavior, not product egress)

Requirements

• VS Code ^1.90.0
• Node >=22 (extension host only, no network)

Run ACKit: Refresh in a fixture workspace (see src/test/runTest.ts test-fixture) — Readiness shows Overall 88/100, Findings grouped, Problems populated, Graph shows AGENTS.md nodes.

Offline-first, deterministic, no telemetry.
