From 77e2472ca0db5a1ba275b2e12b2ba75d1836576a Mon Sep 17 00:00:00 2001 From: Cody Anderson <70287898+arakasi1@users.noreply.github.com> Date: Sat, 5 Sep 2026 02:00:08 -0600 Subject: [PATCH] enhance(#4221): replace installer Read() deny rules with a managed secret-read guard hook (#4236) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(#4221): gsd-secret-read-guard PreToolUse hook + registration Add hooks/gsd-secret-read-guard.js, a blocking PreToolUse guard on Read|Grep|Bash that denies reads of .env, .env. and .secrets (the .env.example/.sample/.template/.dist templates stay readable). Read checks file_path; Grep checks an explicit path and judges the glob per brace alternative; Bash runs a two-pass token scan (quotes, comments, redirects with fd digits, separators, $( )/backtick/<( ) recursion, heredoc bodies never scanned as commands, nested bash -c/eval rescans, git : shapes) with a closed non-reading exemption set for existence checks. Fail-open crash policy; 1 MiB commands are denied as command-too-large; more than 64 glob alternatives as glob-too-complex. Why: Claude Code 2.1.259 makes every `cd DIR && grep …` compound prompt for approval whenever any Read() deny rule exists, even in auto mode. A hook denial is not a permission rule and never arms that check. The installer-written deny rules are retired in the follow-up commit. Registration: hooks.json (Read|Grep|Bash, timeout 5), build-hooks HOOKS_TO_COPY, managed-hooks-registry, runtime-hooks-surface (blocking guard with BLOCKING_GUARD_TIMEOUT_S; Kimi ReadFile|Grep|Shell), shell-command-projection managed sets, installer-migration-report, OpenCode/Kilo plugin (grep tool mapping, include -> glob, dispatch), docs tables in five locales, ADR-766 always-on list, regen:derived fixtures, and a new table-driven unit suite. * test(#4221): pin the secret-read guard in existing hook gates Register gsd-secret-read-guard.js in every existing hook gate: the hooks-crash-policy table (deny row; 6 -> 7 deny cases), plugin-manifest REQUIRED_HOOKS and its Read|Grep|Bash group, docs-hooks-table-parity EXPECTED_SURFACE_HOOKS, install.test MANAGED_JS_HOOKS, install-minimal- hooks JS_HOOKS/BLOCKING_GUARDS, portable-node-runner GUARD_HOOKS, kilo-upgrades PLUGIN_GUARD_HOOKS, the Kimi normalization-parity and typed-payload floors, the OpenCode adapter (grep mapping, include -> glob, three dispatch tests) and a Kimi TOML matcher assertion. * fix(#4221): retire installer Read() deny rules (legacy filter) Rename GSD_CLAUDE_DENY_PERMISSIONS to GSD_CLAUDE_LEGACY_DENY_PERMISSIONS and stop adding the three Read(.env) / Read(.env.*) / Read(.secrets) strings. mergeClaudePermissions now only filters them out of an existing permissions.deny: an absent deny key stays absent, a malformed one is still repaired to [], and an array emptied by the filter is deleted so no `"deny": []` residue is left. Uninstall filters the same legacy list and, symmetric with the Antigravity branch, drops an emptied allow or deny key and an emptied permissions object. Unlike the #2278 allow-side migration there is no surviving current deny list, so the constant is renamed rather than mirrored. Removal is byte-exact: a hand-written identical rule is indistinguishable from the installer's and is removed too (the manifest never recorded permission strings). USER-GUIDE and CONTEXT.md updated. * test(#4221): flip install-regressions deny-rule assertions to the retired shape The fresh-merge, non-destructive merge, idempotency, end-to-end install, reinstall and uninstall assertions now expect no Read(.env*) deny rules and no permissions.deny key on a fresh install; the deny:null repair case is kept. A new describe block covers the legacy filter: retired strings removed with a user entry kept, partial sets, near-miss strings untouched, idempotency, GSD-only deny array deleted, a pre-existing empty deny preserved, and uninstall symmetry for allow/deny/permissions. * chore(#4221): add changeset fragment for PR #4236 * fix(#4221): case-fold names; scan shell stdin and xargs pipes Review round 1 (trek-e): - Blocker: secret-name matching is now case-insensitive in the Read, Grep (path and glob) and Bash paths, so `.ENV` / `.Secrets` on a case-insensitive filesystem are recognized as the same secret file. - Major: a shell interpreter's script is now scanned wherever it comes from. The tokenizer keeps heredoc bodies as per-segment tokens and records separator operators; pass 2 groups by segment id and resolves bash/sh/zsh/dash/ksh/su invocation mode: `-c` (including combined `-lc`) scans the script operand, a file operand is checked as a file (a `<( )` operand's echo/printf output is reconstructed), otherwise stdin is the script and heredocs, here-strings and a piped echo/printf source are scanned. `eval` joins all its operands; `source`/`.` handle process substitution. Data heredocs (`cat <` checks the upstream segment's operands as file names when the sub-command reads (`echo .env | xargs cat`, `find . -name .env | xargs cat`); `-a`/`--arg-file` suppresses the inference; a shell sub-command's `-c` script is scanned. Header, USER-GUIDE bullet and changeset updated; documented gaps now include piped scripts from non-echo sources and `exec`/`timeout` wrappers. 60 new suite cases pin the block and allow shapes. --------- Co-authored-by: Tom Boucher --- .changeset/brave-wasps-wander.md | 5 + .kilo/plugins/gsd-core.js | 12 + .opencode/plugins/gsd-core.js | 12 + CONTEXT.md | 2 +- bin/install.js | 57 +- docs/ARCHITECTURE.md | 1 + docs/INVENTORY-MANIFEST.json | 1 + docs/INVENTORY.md | 1 + docs/USER-GUIDE.md | 21 +- .../766-claude-code-plugin-manifest-module.md | 2 +- docs/how-to/install-on-your-runtime.md | 8 +- docs/ja-JP/ARCHITECTURE.md | 1 + docs/ja-JP/INVENTORY.md | 1 + docs/ko-KR/ARCHITECTURE.md | 1 + docs/ko-KR/INVENTORY.md | 1 + docs/pt-BR/ARCHITECTURE.md | 1 + docs/pt-BR/INVENTORY.md | 1 + docs/zh-CN/ARCHITECTURE.md | 1 + docs/zh-CN/INVENTORY.md | 1 + hooks/gsd-secret-read-guard.js | 1079 +++++++++++++++++ hooks/hooks.json | 6 + hooks/managed-hooks-registry.cjs | 1 + scripts/build-hooks.js | 2 + src/installer-migration-report.cts | 1 + src/runtime-hooks-surface.cts | 31 + src/shell-command-projection.cts | 4 + tests/docs-hooks-table-parity.test.cjs | 1 + tests/fixtures/install-tree/antigravity.json | 1 + tests/fixtures/install-tree/augment.json | 1 + tests/fixtures/install-tree/claude-local.json | 1 + tests/fixtures/install-tree/claude.json | 1 + tests/fixtures/install-tree/codebuddy.json | 1 + tests/fixtures/install-tree/hermes.json | 1 + tests/fixtures/install-tree/kilo.json | 1 + tests/fixtures/install-tree/kimi-code.json | 1 + tests/fixtures/install-tree/opencode.json | 1 + tests/fixtures/install-tree/pi.json | 1 + tests/fixtures/install-tree/qwen.json | 1 + tests/gsd-secret-read-guard.test.cjs | 375 ++++++ tests/hooks-crash-policy.test.cjs | 24 +- tests/install-minimal-hooks.test.cjs | 2 + tests/install-regressions.test.cjs | 179 ++- tests/install.test.cjs | 1 + tests/kilo-upgrades.test.cjs | 3 +- .../kimi-guard-normalization-parity.test.cjs | 1 + tests/kimi-guard-typed-payload-reads.test.cjs | 1 + tests/kimi-upgrades.test.cjs | 14 + tests/opencode-plugin-adapter.test.cjs | 48 + tests/plugin-manifest.test.cjs | 18 +- tests/portable-node-runner.install.test.cjs | 1 + 50 files changed, 1862 insertions(+), 71 deletions(-) create mode 100644 .changeset/brave-wasps-wander.md create mode 100644 hooks/gsd-secret-read-guard.js create mode 100644 tests/gsd-secret-read-guard.test.cjs diff --git a/.changeset/brave-wasps-wander.md b/.changeset/brave-wasps-wander.md new file mode 100644 index 000000000..83433abe3 --- /dev/null +++ b/.changeset/brave-wasps-wander.md @@ -0,0 +1,5 @@ +--- +type: Changed +pr: 4236 +--- +Secret-file read protection moved from installer-written permission deny rules to a managed hook. The Claude Code installer no longer writes `Read(.env)` / `Read(.env.*)` / `Read(.secrets)` into `permissions.deny`, and removes those three strings (byte-equal only) from existing installs on install and uninstall — on Claude Code >= 2.1.259 any `Read()` deny rule made every `cd DIR && grep …` compound prompt for approval, even in `auto` mode. The same protection now ships as the always-on `gsd-secret-read-guard.js` PreToolUse hook (matcher `Read|Grep|Bash`; Kimi `ReadFile|Grep|Shell`; OpenCode/Kilo plugin dispatch), which denies reads of `.env`, `.env.` and `.secrets` — matched case-insensitively — via Read, Grep (explicit path or a selecting glob, judged per brace alternative) and Bash (operands, input redirects, `$( )`/backtick/`<( )` bodies, `git show :`). A shell interpreter (`bash`/`sh`/`zsh`/`dash`/`ksh`) has its script scanned however it arrives — `-c '…'`, a `<( )` file operand, a heredoc / here-string, or a pipe from a knowable `echo`/`printf` source — plus `eval`'s joined operands, a `source`/`.` process-substitution operand, and `find … | xargs cat` pipelines (upstream literal names become the sub-command's read operands). `.env.example` / `.env.sample` / `.env.template` / `.env.dist` stay readable, and existence checks (`[ -f .env ]`, `ls .env*`) pass. Documented gaps: `$VAR` indirection, shell globs, interpreter one-liners, a piped script from a non-`echo`/`printf` source (`cat gen.sh | bash`, `curl … | sh`), reads inside executed scripts, and a Grep `glob: '*'` reaching a non-gitignored `.env`. Breaking: a hand-written deny rule identical to one of the three strings is removed too; re-add it if you want both layers. Cursor, Windsurf, Cline, Copilot, Codex and ZCode have no per-tool hook matcher and are not covered (they never had the deny rules either). diff --git a/.kilo/plugins/gsd-core.js b/.kilo/plugins/gsd-core.js index 5b7c3dfdb..c67506767 100644 --- a/.kilo/plugins/gsd-core.js +++ b/.kilo/plugins/gsd-core.js @@ -135,6 +135,7 @@ let currentCwd = process.cwd(); const TOOL_NAME_MAP = { read: "Read", + grep: "Grep", write: "Write", edit: "Edit", apply_patch: "MultiEdit", @@ -173,6 +174,10 @@ function mapToolInput(args) { // Bash command if (args.command !== undefined) input.command = args.command; + // Grep file filter (OpenCode uses include; Claude uses glob) + const glob = args.glob ?? args.include; + if (glob !== undefined) input.glob = glob; + // Web if (args.url !== undefined) input.url = args.url; if (args.query !== undefined) input.query = args.query; @@ -576,6 +581,13 @@ const GsdCorePlugin = async ({ directory } = {}) => { const r = runHook("gsd-workflow-guard.js", prePayload()); handleHookResult(r, output); } + + // 6. gsd-secret-read-guard.js — hard-block reads of .env / .env. / + // .secrets via Read (file_path), Grep (path or glob) and Bash (command) + if (["Read", "Grep", "Bash"].includes(claudeTool)) { + const r = runHook("gsd-secret-read-guard.js", prePayload()); + handleHookResult(r, output); + } }, // ── tool.execute.after — PostToolUse hooks ───────────────────────── diff --git a/.opencode/plugins/gsd-core.js b/.opencode/plugins/gsd-core.js index 5b7c3dfdb..c67506767 100644 --- a/.opencode/plugins/gsd-core.js +++ b/.opencode/plugins/gsd-core.js @@ -135,6 +135,7 @@ let currentCwd = process.cwd(); const TOOL_NAME_MAP = { read: "Read", + grep: "Grep", write: "Write", edit: "Edit", apply_patch: "MultiEdit", @@ -173,6 +174,10 @@ function mapToolInput(args) { // Bash command if (args.command !== undefined) input.command = args.command; + // Grep file filter (OpenCode uses include; Claude uses glob) + const glob = args.glob ?? args.include; + if (glob !== undefined) input.glob = glob; + // Web if (args.url !== undefined) input.url = args.url; if (args.query !== undefined) input.query = args.query; @@ -576,6 +581,13 @@ const GsdCorePlugin = async ({ directory } = {}) => { const r = runHook("gsd-workflow-guard.js", prePayload()); handleHookResult(r, output); } + + // 6. gsd-secret-read-guard.js — hard-block reads of .env / .env. / + // .secrets via Read (file_path), Grep (path or glob) and Bash (command) + if (["Read", "Grep", "Bash"].includes(claudeTool)) { + const r = runHook("gsd-secret-read-guard.js", prePayload()); + handleHookResult(r, output); + } }, // ── tool.execute.after — PostToolUse hooks ───────────────────────── diff --git a/CONTEXT.md b/CONTEXT.md index ee12c6fda..e913c8ce7 100644 --- a/CONTEXT.md +++ b/CONTEXT.md @@ -245,7 +245,7 @@ Module owning the `{"type":"commonjs"}` module-type marker GSD writes beside its Module owning validation for Installer Migration Module records and planned actions.

A **fault** is `error(message, reason)` — stderr, exit **1**, structured `{ok:false,reason,message}` envelope under `--json-errors`. A **degraded result** is `output({ error: … })` — stdout, exit **0**, `--json-errors` does not apply — and means the command ran to completion and is reporting a condition (absent artifact, and in practice also missing-argument and unusable-input cases) through its result; a caller detects it by inspecting the payload, never by exit code. Ratified across **60 sites in 9 modules** (`state` 25, `verify` 8, `workstream` 7, `frontmatter` 6, `commands` 5, `template` 3, `gsd2-import` 2, `phase` 2, `roadmap` 2) because normalizing them to exit 1 is a Hyrum's Law break over a CRITICAL radius (`get_impact(cmdStateSnapshot)`; `output` has 170 direct callers). #2966/#2980 record "42 sites" — that counts only literals whose FIRST key is `error` (the `output\(\{\s*error:` regex); 18 more put another key first (`{found:false, error}`) and are identical in contract, so 60 is the population and 42 is a subset. New code prefers the fault path or a named-field result (`{updated:false, reason}`), not a 61st site. Known cost carried by the decision: the exit code does not distinguish absent from unusable, which is ADR-1411's "corrupt is not absent" open edge. Docs: `docs/json-errors.md` → "Degraded results vs faults". Extracted from the Core module per ADR-857 rollout phase 1 (#859) so feature modules (`graphify`, `intel`, `audit`, `profile-pipeline`) depend on a small I/O seam instead of the core god-module; the `core.cjs` re-export spine was retired in epic #1267, so callers import this leaf directly.

For a legitimate milestone reset or large deletion, bypass once with the single-use sentinel — write the target's path into `.planning/.gsd-allow-shrink` (fresh within 15 minutes; consumed by the allowed write) — or, interactively, with `GSD_ALLOW_PLANNING_SHRINK=1` in the runtime's environment. Scope the guarantee accordingly: this stops accidental and single-shot collapse, and is not a defense against a determined agent — the sentinel is a plain file, so anything with shell access can arm one; what it buys is that the bypass becomes a deliberate, path-bound, single-use and auditable action rather than a sentence to reason past (always active, blocking; #2255, fix 3 of #973) +- `gsd-secret-read-guard.js` — Hard-blocks reads of secret files — `.env`, `.env.` and `.secrets`, matched case-insensitively (`.ENV`, `.Secrets`) — through Read (`file_path`), Grep (an explicit `path`, or a `glob` that selects them, judged per brace alternative) and Bash (operands, input redirects, `$( )` / backtick / `<( )` bodies, and `git show :` shapes). A shell interpreter (`bash`/`sh`/`zsh`/`dash`/`ksh`) has its script scanned however it arrives — `-c '…'`, a `<( )` file operand, a heredoc / here-string, or a pipe from a knowable `echo`/`printf` source (`echo cat .env | bash`) — as do `eval`'s joined operands, a `source`/`.` process-substitution operand, and `find … | xargs cat` pipelines (upstream literal names become the sub-command's read operands). `.env.example` / `.env.sample` / `.env.template` / `.env.dist` stay readable (they are the templates GSD's own phase prompt reads — a real secret stored under one of those names is not protected), and existence checks (`[ -f .env ]`, `ls .env*`, `test`, `stat`, `rm`, `touch`, `echo`, …) pass. Not covered, by construction: `$VAR` indirection (`bash -c "$CMD"`), shell globs (`cat .e*`), interpreter one-liners, a piped script from a non-`echo`/`printf` source (`cat gen.sh | bash`, `curl … | sh`), reads inside scripts the agent runs, and a Grep `glob: '*'` reaching a `.env` that is not gitignored — none are statically resolvable by a hook.
