From ef8f7b216b188f23fd68163c808edef85ca466fd Mon Sep 17 00:00:00 2001 From: Robin Champsaur Date: Fri, 3 Apr 2026 23:50:27 +0700 Subject: [PATCH 01/10] =?UTF-8?q?feat:=20AGS=20v0=20=E2=80=94=20cross-agen?= =?UTF-8?q?t=20skill=20management=20CLI?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Zero-dependency Bun CLI that discovers, measures, and manages AI agent skills across Claude Code, Cursor, and Codex. Commands: scan — discover all skills, commands, agents, and rules with health badges, scope/type/agent filtering, and colored grouped output skill-cost — context tax breakdown per agent with bar charts and optimization suggestions grab — install skills from GitHub blob URLs rm — remove skills by name or path stats — usage dashboard with sessions, PRs created, token usage, MCP integrations, skill/subagent invocations, and peak hours heatmap list-agents — detect installed agents with skill counts Design: - Agent-first: --json on every command for structured agent consumption - Zero runtime deps: Bun built-ins for fs, fetch, spawn, glob - Scans Claude Code, Cursor, and Codex directories exhaustively (skills, commands, agents, rules — both flat .md and SKILL.md formats) - Ships with ags-manager SKILL.md for agent self-discovery - Shell completions for zsh and bash (Homebrew auto-install) - Cross-compile targets: darwin-arm64, darwin-x64, linux-x64 Co-Authored-By: Claude Opus 4.6 (1M context) --- .gitignore | 4 + build.ts | 59 ++++ bun.lockb | Bin 0 -> 1979 bytes completions/_ags | 88 ++++++ completions/ags.bash | 49 +++ package.json | 18 ++ skills/ags-manager/SKILL.md | 124 ++++++++ src/commands/budget.ts | 220 ++++++++++++++ src/commands/grab.ts | 101 ++++++ src/commands/list-agents.ts | 99 ++++++ src/commands/rm.ts | 126 ++++++++ src/commands/scan.ts | 185 +++++++++++ src/commands/stats.ts | 590 ++++++++++++++++++++++++++++++++++++ src/core/agents.ts | 178 +++++++++++ src/core/health.ts | 61 ++++ src/core/parser.ts | 179 +++++++++++ src/core/scanner.ts | 152 ++++++++++ src/core/tokens.ts | 22 ++ src/index.ts | 226 ++++++++++++++ src/types.ts | 170 +++++++++++ src/utils/git.ts | 39 +++ src/utils/github.ts | 60 ++++ src/utils/output.ts | 155 ++++++++++ tsconfig.json | 18 ++ 24 files changed, 2923 insertions(+) create mode 100644 .gitignore create mode 100644 build.ts create mode 100755 bun.lockb create mode 100644 completions/_ags create mode 100644 completions/ags.bash create mode 100644 package.json create mode 100644 skills/ags-manager/SKILL.md create mode 100644 src/commands/budget.ts create mode 100644 src/commands/grab.ts create mode 100644 src/commands/list-agents.ts create mode 100644 src/commands/rm.ts create mode 100644 src/commands/scan.ts create mode 100644 src/commands/stats.ts create mode 100644 src/core/agents.ts create mode 100644 src/core/health.ts create mode 100644 src/core/parser.ts create mode 100644 src/core/scanner.ts create mode 100644 src/core/tokens.ts create mode 100755 src/index.ts create mode 100644 src/types.ts create mode 100644 src/utils/git.ts create mode 100644 src/utils/github.ts create mode 100644 src/utils/output.ts create mode 100644 tsconfig.json diff --git a/.gitignore b/.gitignore new file mode 100644 index 0000000..dd6e803 --- /dev/null +++ b/.gitignore @@ -0,0 +1,4 @@ +node_modules/ +dist/ +*.log +.DS_Store diff --git a/build.ts b/build.ts new file mode 100644 index 0000000..8186478 --- /dev/null +++ b/build.ts @@ -0,0 +1,59 @@ +import { $ } from "bun";
