broken chains fail validation - hook management generalized across PreToolUse/PostToolUse/SessionStart/Stop Co-Authored-By: Claude Fable 5 --- code-warden/CONFIGURE.md | 37 ++- code-warden/bin/code-warden.js | 1 + code-warden/codewarden.json | 3 + code-warden/install.js | 7 +- code-warden/tools/get-context.js | 34 +-- code-warden/tools/governance-report.js | 102 +------ .../tools/hooks/claude/install-hooks.js | 89 ++++--- .../tools/hooks/claude/uninstall-hooks.js | 37 +-- .../tools/hooks/claude/warden-audit-hook.js | 38 +++ .../tools/hooks/claude/warden-scope-hook.js | 20 +- .../tools/hooks/claude/warden-session-hook.js | 81 ++++++ .../tools/hooks/claude/warden-stop-hook.js | 88 +++++++ .../hooks/codex/warden-apply-patch-hook.js | 6 +- code-warden/tools/lib/audit-ledger.js | 200 ++++++++++++++ code-warden/tools/lib/config.js | 17 +- code-warden/tools/lib/context-discovery.js | 54 ++++ code-warden/tools/lib/git-info.js | 44 ++++ code-warden/tools/lib/hook-events.js | 100 +++++++ code-warden/tools/lib/receipt-audit.js | 108 ++++++++ code-warden/tools/lib/scan-core.js | 101 +++++++ code-warden/tools/lib/scope-store.js | 33 ++- code-warden/tools/receipt.js | 43 ++- code-warden/tools/tests/audit-ledger-tests.js | 198 ++++++++++++++ .../tools/tests/lifecycle-hook-tests.js | 249 ++++++++++++++++++ .../tools/tests/receipt-audit-tests.js | 243 +++++++++++++++++ code-warden/tools/tests/run-all-tests.js | 3 + code-warden/tools/tests/scope-tests.js | 36 ++- 27 files changed, 1767 insertions(+), 205 deletions(-) create mode 100644 code-warden/tools/hooks/claude/warden-audit-hook.js create mode 100644 code-warden/tools/hooks/claude/warden-session-hook.js create mode 100644 code-warden/tools/hooks/claude/warden-stop-hook.js create mode 100644 code-warden/tools/lib/audit-ledger.js create mode 100644 code-warden/tools/lib/context-discovery.js create mode 100644 code-warden/tools/lib/git-info.js create mode 100644 code-warden/tools/lib/hook-events.js create mode 100644 code-warden/tools/lib/receipt-audit.js create mode 100644 code-warden/tools/lib/scan-core.js create mode 100644 code-warden/tools/tests/audit-ledger-tests.js create mode 100644 code-warden/tools/tests/lifecycle-hook-tests.js create mode 100644 code-warden/tools/tests/receipt-audit-tests.js diff --git a/code-warden/CONFIGURE.md b/code-warden/CONFIGURE.md index a8e24b2..2109d41 100644 --- a/code-warden/CONFIGURE.md +++ b/code-warden/CONFIGURE.md @@ -37,7 +37,9 @@ Located at the root of the skill folder.
