v0.8.1

2026-09-20 Latest

Added

  • Expanded the pr-to-spec skill into a marketplace-grade operator guide with

Security

  • Execute local Git inspection with execFileSync argument arrays instead of a
  • Remove the GitHub token from the MCP analyze_pr tool-input schema; the
  • Update the MCP SDK to 1.30.0 and YAML to 2.9.0, clearing all known production

Fixed

  • Declare the node24 Actions runtime in action.yml. GitHub removes node20 on
  • Require --repo and --pr only for root GitHub-PR analysis so documented
  • Ship a self-contained MCP bundle, declare the custom skill path in the plugin

v0.8.0

2026-03-18

Added

  • MCP Server (servers/pr-spec-analyzer.ts) — 6-tool Model Context Protocol server exposing analyze_pr, scan_local, check_drift, set_intent, show_intent, and analyze_assumptions via stdio transport
  • Claude Code plugin metadata (.claude-plugin/plugin.json, .mcp.json) — enables pr-to-spec as a standalone MCP plugin for Claude Code, Cursor, and Windsurf
  • @modelcontextprotocol/sdk dependency for MCP protocol compliance
  • --debug flag for CLI — logs API request URLs, git commands, and timing info to stderr
  • PR_TO_SPEC_DIR env var — configurable storage directory (default: .pr-to-spec)
  • Security test suite (tests/security.test.ts) — webhook URL validation, custom_command rejection, prototype pollution guard
  • API error test suite (tests/github-errors.test.ts) — 401, 403, 404, 422, rate limit, large PR truncation
  • README: documented all subcommands (intent, check, contract, graph, feedback)
  • README: exit code 4 (gate_failed)
  • README: troubleshooting section with common errors

Security

  • Removed custom_command contract type — eliminated command injection vector from arbitrary shell execution. The type is preserved in the schema but always fails with a clear deprecation message.
  • Webhook SSRF prevention — validates webhook URLs: requires HTTPS, rejects localhost, private IPs (10.x, 172.16-31.x, 192.168.x), and link-local addresses (169.254.x).
  • Reduced GitHub Action permissions — contents: write → contents: read (the action only reads PRs and posts comments).
  • Prototype pollution guard — --field extraction blocks __proto__, constructor, and prototype traversal.
  • Secret masking — webhook URLs are masked in error output to prevent leaking sensitive endpoints.

Fixed

  • Version sync — CLI and Action version strings updated from stale 0.6.0 to 0.8.0
  • API error messages — GitHub API errors now return user-friendly messages instead of raw Octokit exceptions (401, 403, 404, 422, rate limit)
  • Git error messages — scan/check commands now surface clear messages for "not a git repo" and "unknown revision" errors
  • Large PR warning — warns when GitHub API returns 300 files (the per-page maximum), indicating truncation

Changed

  • 384 tests passing (all existing tests updated for security changes)

v0.7.0

2026-03-17

Added

  • Intent DAG: Graph-based intent tracking with spec fragments, decision taxonomy, and propagation engine
  • graph subcommand — query ancestors/descendants, compute impact, view graph stats
  • contract subcommand — declarative contract verification (no_new_dependencies, no_file_outside_scope, max_files_changed, no_pattern_in_diff, require_pattern_in_diff, no_new_exports, custom_command)
  • intent approve / intent lock — approval workflow (draft → approved → locked)
  • intent gate — evaluate gate policy (min_confidence, require_no_stale, require_no_must_ask)
  • Graph materialization — gate and contract results become audit trail nodes
  • Feedback ingestion — learn from reviews to improve future classifications
  • 364 tests (84 new tests for Intent DAG)

Changed

  • Contract evaluator: smarter no_new_dependencies detection (lock files vs manifest files)
  • Protocol envelope: gate_failed status with exit code 4
  • check subcommand: integrated contract evaluation and gate checks

v0.6.0

2026-03-17

Changed

  • Renamed: pr-to-prompt → pr-to-spec
  • Positioning: "The flight envelope for agentic coding"

Added

  • DiffSource abstraction — works on any diff (local branches, staged changes, GitHub PRs)
  • scan subcommand — analyze local git changes without GitHub
  • intent subcommand — declare expected scope, risk ceiling, change type
  • check subcommand — scan + drift detection against declared intent
  • Drift signals: scope_creep, forbidden_touch, risk_escalation, size_overrun, type_mismatch
  • Agent protocol envelope wraps all --json output
  • Claude Code skill manifest (.claude/skills/pr-to-spec/SKILL.md)

Backwards Compatible

  • pr-to-spec --repo owner/repo --pr 42 --json still works unchanged

Added

  • JSON output format with --format json for agent-friendly piping (#7)
  • Bash-friendly CLI flags: --quiet, --field , --json shorthand (#8)
  • Exit code semantics: 0=success, 1=error, 2=high-risk PR detected (#8)
  • decision_prompt field in spec for agent-driven review decisions (#12)
  • Webhook notifications via webhook_url input in GitHub Action (#11)
  • Example integrations: claude-code.md, bash-agent.sh, github-action-chain.yml (#10)

Changed

  • README rewritten with agent-first positioning and piping examples (#9)
