From 25eb3e1950261c6cb5042f010774311b808d0193 Mon Sep 17 00:00:00 2001 From: Iliass JABALI Date: Sun, 22 Mar 2026 00:16:05 +0000 Subject: [PATCH 1/4] feat: add agentspec claude-status command and dual-auth support for Claude subscription + API key MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## What this does AgentSpec previously required ANTHROPIC_API_KEY for generate and scan. This change adds full support for Claude Pro/Max subscriptions so users with a Claude.ai plan can run AgentSpec without any API key. ## New command: agentspec claude-status Inspect the full Claude auth environment in one shot: agentspec claude-status # table output agentspec claude-status --json # machine-readable, exit 1 if not ready Reports: - CLI: installed, version, authenticated, account email, plan (Pro/Max/Free) - API: key set, masked preview, live HTTP probe to /v1/models, base URL - Env: AGENTSPEC_CLAUDE_AUTH_MODE override, ANTHROPIC_MODEL, resolved mode Implemented via probeClaudeAuth() in adapter-claude/src/auth.ts which collects all data without throwing, then renders it in claude-status.ts. ## Auth resolution (CLI first) resolveAuth() in auth.ts picks the method in this order: 1. Claude CLI — if installed + authenticated (subscription users) 2. ANTHROPIC_API_KEY — fallback for CI / API-only setups 3. Neither — single combined error with setup instructions for both Override: AGENTSPEC_CLAUDE_AUTH_MODE=cli|api ## CLI stdin fix runClaudeCli() now pipes the user message via stdin (spawnSync input:) instead of as a CLI argument, avoiding ARG_MAX limits on large manifests. ## Why not @anthropic-ai/claude-agent-sdk The agent SDK is designed for persistent multi-turn coding assistants (session management, resume cursors, tool approval gates). AgentSpec generate/scan are one-shot calls — the SDK would be ~2500 lines of adapter code with almost all of it unused. Our spawnSync approach is the correct scope match: zero extra dependency, auth for free, simple to test and debug. The only tradeoff is no streaming in CLI mode. ## Files New: - packages/adapter-claude/src/auth.ts — resolveAuth, isCliAvailable, probeClaudeAuth - packages/adapter-claude/src/cli-runner.ts — runClaudeCli via spawnSync stdin - packages/cli/src/commands/claude-status.ts — new CLI command - packages/adapter-claude/src/__tests__/auth.test.ts — 16 tests - packages/adapter-claude/src/__tests__/cli-runner.test.ts — 9 tests - docs/guides/claude-auth.md — full auth guide incl. claude-status usage - examples/gymcoach/docker-compose.yml — local Postgres + Redis Updated: - adapter-claude/index.ts — routes generate/repair through resolveAuth - cli/commands/generate.ts + scan.ts — remove hard API key blocks, show auth label - cli/cli.ts — registers claude-status command - docs/reference/cli.md — claude-status section, updated generate/scan auth docs - docs/concepts/adapters.md + quick-start.md — dual-auth examples throughout Tests: 63 passing in adapter-claude, 1039 passing workspace-wide --- docs/.vitepress/config.mts | 7 +- docs/concepts/adapters.md | 31 +- docs/guides/claude-auth.md | 236 +++++++++++ docs/quick-start.md | 19 +- docs/reference/cli.md | 83 +++- .../adapter-claude/src/__tests__/auth.test.ts | 220 ++++++++++ .../src/__tests__/claude-adapter.test.ts | 63 +-- .../src/__tests__/cli-runner.test.ts | 137 ++++++ packages/adapter-claude/src/auth.ts | 393 ++++++++++++++++++ packages/adapter-claude/src/cli-runner.ts | 159 +++++++ packages/adapter-claude/src/index.ts | 165 +++++--- packages/cli/src/__tests__/cli.test.ts | 7 +- packages/cli/src/__tests__/generate.test.ts | 1 + packages/cli/src/__tests__/scan.test.ts | 8 +- packages/cli/src/cli.ts | 2 + packages/cli/src/commands/claude-status.ts | 190 +++++++++ packages/cli/src/commands/generate.ts | 20 +- packages/cli/src/commands/scan.ts | 17 +- 18 files changed, 1599 insertions(+), 159 deletions(-) create mode 100644 docs/guides/claude-auth.md create mode 100644 packages/adapter-claude/src/__tests__/auth.test.ts create mode 100644 packages/adapter-claude/src/__tests__/cli-runner.test.ts create mode 100644 packages/adapter-claude/src/auth.ts create mode 100644 packages/adapter-claude/src/cli-runner.ts create mode 100644 packages/cli/src/commands/claude-status.ts diff --git a/docs/.vitepress/config.mts b/docs/.vitepress/config.mts index 950e112..2c0d35d 100644 --- a/docs/.vitepress/config.mts +++ b/docs/.vitepress/config.mts @@ -58,9 +58,10 @@ export default defineConfig({ text: 'Capabilities', collapsed: false, items: [ - { text: 'Add Tools', link: '/guides/add-tools' }, - { text: 'Add Memory', link: '/guides/add-memory' }, - { text: 'Add Guardrails', link: '/guides/add-guardrails' }, + { text: 'Add Tools', link: '/guides/add-tools' }, + { text: 'Add Memory', link: '/guides/add-memory' }, + { text: 'Add Guardrails', link: '/guides/add-guardrails' }, + { text: 'Claude Authentication', link: '/guides/claude-auth' }, ], }, { diff --git a/docs/concepts/adapters.md b/docs/concepts/adapters.md index 125d86d..f152fc2 100644 --- a/docs/concepts/adapters.md +++ b/docs/concepts/adapters.md @@ -19,9 +19,10 @@ agent.yaml ┌─────────────────────────────────┐ │ @agentspec/adapter-claude │ │ │ +│ resolveAuth() │◄── CLI login or ANTHROPIC_API_KEY │ loadSkill('langgraph') │◄── src/skills/langgraph.md │ buildContext(manifest) │ -│ claude.messages.create(...) │ +│ claude (subscription or API) │ └─────────────────────────────────┘ │ ▼ @@ -33,6 +34,17 @@ agentspec generate --output ./generated/ This approach covers **all manifest fields** without exhaustive TypeScript templates.

Also fixes cleanupTempFile which called unlinkSync on a directory (would always throw and leave temp dirs behind). - generate.ts / scan.ts: derive authLabel from resolveAuth() instead of isCliAvailable() so AGENTSPEC_CLAUDE_AUTH_MODE override is reflected in the spinner (Copilot comment on both commands) - generate.ts / scan.ts: resolve auth once and pass into generateWithClaude via new options.auth field to avoid redundant subprocess call (PERF-01) - generate.ts: fix runDeployTarget helm path to wrap generateWithClaude in try/catch with graceful error output (QUAL-03) - index.ts: wrap repairYaml YAML content in XML tags to prevent prompt injection from adversarial agent.yaml files (SEC-02); truncate to 64 KB - skills/guidelines.md: add security preamble instructing Claude to treat context_manifest and context_file XML tags as data only, never instructions - docs: correct timeout example in error table from 120s to 300s - tests: add claude-status.test.ts (9 tests) covering JSON output shape and exit code 0/1 for all three resolved modes - tests: add probeClaudeAuth coverage (8 tests) to auth.test.ts - tests: add repairYaml coverage (4 tests) and XML tag assertions to claude-adapter.test.ts; update buildContext tests for new XML format - tests: remove dead node:fs mock from cli-runner.test.ts - tests: update scan/generate test mocks from isCliAvailable to resolveAuth - cli.test.ts: pass AGENTSPEC_CLAUDE_AUTH_MODE=api in generate tests to prevent them hitting real Claude CLI on developer machines --- docs/guides/claude-auth.md | 2 +-
