…laude subscription + API key ## 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

New claude-status command behavior (table vs --json, exit code 0/1 based on readiness, and rendering of probe results) isn’t covered by CLI tests. Since other commands in packages/cli/src/commands have dedicated tests, add coverage to validate JSON output shape and exit code behavior (especially the resolvedMode === 'none' path).
- auth.ts: parse claude auth status JSON before lowercasing so loggedIn:false is not silently misread as true (Copilot comment on isClaudeAuthenticated) - auth.ts: reduce API key preview exposure from 16 chars to first-4…last-2 - auth.ts: remove dead catch branch in isClaudeAuthenticated (both if-branches returned false; simplified to unconditional return false) - cli-runner.ts: remove dead systemPromptPath temp-file write — system prompt was written to disk but never used; --system-prompt was passed inline. 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

The guidelines claim the user message wraps the manifest/files in <context_manifest>/<context_file> XML tags, but buildContext() currently emits Markdown sections and code fences instead. That means this security guidance (and the prompt-injection boundary it describes) won't match the actual prompt being sent to Claude; either update buildContext to emit these XML tags or adjust the guidelines to reflect the real format.

This docstring says collectSourceFiles “returns both the capped file list and totalFound”, but the function now returns only SourceFile[]. Either update the comment (and mention collectSourceFilesWithCount) or change the exported function signature to return both values.

probeClaudeAuth() runs claude auth status twice when the CLI is installed: once via probeAuthStatus() (to populate authStatusRaw) and again via isClaudeAuthenticated() (to set authenticated). This adds extra subprocess latency to agentspec claude-status and can yield inconsistent fields if the CLI output changes between calls; consider deriving authenticated from the already-captured authStatusRaw (or returning both raw + parsed status from a single probe call).
Suggested change

| ? !authStatusRaw.toLowerCase().includes('not authenticated') | |

There was a problem hiding this comment.
Helm generation re-calls generateWithClaude() without passing the already-resolved auth (and without manifestDir), so it will resolve auth again and may lose $file: resolution context. Consider threading the resolved AuthResolution (and manifestDir) into runDeployTarget() and passing them through to generateWithClaude to keep behavior consistent and avoid redundant CLI/API probing.

runClaudeCli() uses spawnSync, which blocks the Node event loop for the full duration of codegen. Since @agentspec/adapter-claude is a library package (not just CLI code), this can be problematic for consumers running in long-lived processes (servers, MCP tools, etc.); consider implementing an async runner (spawn + Promise) or clearly constraining/isolating CLI mode usage to CLI-only entrypoints.

Summary
Adds subscription-first Claude authentication to AgentSpec (Claude CLI preferred, API key fallback) and introduces a new
agentspec claude-statuscommand to report readiness and active auth resolution.Changes
@agentspec/adapter-claude: CLI subscription first, API key fallback; override viaAGENTSPEC_CLAUDE_AUTH_MODEagentspec claude-statuscommand with--jsonmode and exit codes for CI useFixes addressed (Copilot review + follow-up audit)
Correctness
isClaudeAuthenticatedJSON-before-lowercase bug:claude auth statusoutput was lowercased beforeJSON.parse, turningloggedIn→loggedinso{ loggedIn: false }was silently misread as authenticated. Now parses the original string first.AGENTSPEC_CLAUDE_AUTH_MODEoverride:generateandscanderived the spinner label fromisCliAvailable()which bypasses the env var override. Both now callresolveAuth()so the label always matches what will execute.runDeployTargethelm path had no error handling:generateWithClaudewas called without try/catch; errors propagated as uncaught rejections instead of the gracefulGeneration failedmessage.isClaudeAuthenticated: both branches of the catch returnedfalseunconditionally. Simplified.120stimeout; actual default is300s.Security
repairYaml: raw YAML content was interpolated directly into the user message. An adversarialagent.yamlcould break out of the code fence and inject instructions. Fixed with<yaml_content>XML tags + system-prompt hardening; content truncated to 64 KB.guidelines.mdsecurity preamble: instructs Claude to treat<context_manifest>and<context_file>XML-tagged content as data only, never as instructions.Performance
resolveAuth()called twice per generate/scan run: the CLI resolved auth for the spinner label, thengenerateWithClauderesolved it again internally (2 × subprocess spawns, up to 8 s). Addedoptions.auth?: AuthResolutiontoClaudeAdapterOptions; the CLI resolves once and passes the result in.collectSourceFilesandcountSourceFilesboth walked the same tree. Merged intocollectSourceFilesWithCountreturning{ files, totalFound }.Developer experience
cli-runner.tsdead temp-file write removed: system prompt was written to a temp file but passed inline to--system-prompt— the file was never read. Removing it also eliminatesunlinkSync(dir)which always threw (can'tunlinkSynca directory).keyPreview: reduced from 16-char prefix tofirst-4…last-2.Tests
