* test(#3523): rewrite two undetected source-greps as behavioral tests Both sites read a real shipped hook and text-searched it, and both were invisible to local/no-source-grep because the path was bound to a separate const the rule never resolves back to its literal. tests/check-update-config-dir.test.cjs carried three such reads, not the one the issue cites. All three are replaced by a harness that runs the real hooks/gsd-check-update.js under a fake HOME and observes the config dirs detectConfigDir resolved, via the env the hook hands its worker. Coverage now includes the CLAUDE_CONFIG_DIR precedence cases and the full adjacent-pair search order the deleted static grep only asserted for one pair. tests/security-prompt-injection.security.test.cjs asserted the scanner hook's SOURCE TEXT contained each canonical MARKDOWN_LINK_PATTERNS regex source. It now drives probes through the real hook and asserts the emitted ruleId, with a completeness gate so a new canonical pattern without a probe fails loudly, plus safePredicate parity the text grep never checked. No allow-test-rule marker is added. The now-false marker on check-update-config-dir.test.cjs is removed and its identity-allowlist entry pruned, which the ratchet requires. Refs #3464 * feat(#3523): emit typed findings IR from the read-injection scanner The scanner built a structured findings array internally and discarded the structure when rendering its advisory sentence, so the only thing a test could assert on was that prose. CONTRIBUTING's 'Prohibited: Raw Text Matching on Test Outputs' names that exact situation and prescribes adding the typed surface rather than matching the text. findings is now an array of {ruleId, match} records and the advisory is derived from it through a single renderFinding mapper, so the rendered text and the IR cannot drift. The array is emitted additively on hookSpecificOutput for both the advisory and blocking output shapes. The advisory string itself is unchanged, byte for byte: verified across six payload shapes (single markdown-link hit, 3+ finding HIGH, invisible unicode, unicode tag block, injection-pattern-only, mixed) by running the pristine and modified hooks against identical stdin and comparing. 28 existing assertions across four suites substring-match that string. The #3523 parity assertions now read the IR, and a new test binds the two surfaces together by asserting every MD-LINK ruleId in findings appears in the advisory and that the reported pattern count matches findings.length. Refs #3464 * docs(#3523): document the read-injection scanner output contract The scanner had no subsection under Security Hooks, only a one-line table row. Documents its trigger events, severity thresholds, skip conditions, rule ids, and the findings IR added alongside the advisory. Refs #3464 * fix(#3523): bind every finding family to the advisory, freeze rule ids Two review findings on the typed-IR commit. The parity test filtered on MD-LINK- and so bound only one of the four finding families to the rendered advisory; the other three were covered only by the pattern count, which catches a length mismatch but not wrong text. It now drives a payload producing all four families at once, asserts all four are present so it cannot silently degrade, and checks each one's expected rendering against an expectation table coded independently of the hook's own mapper. The three synthetic rule ids were written twice each — once at the push site, once in renderFinding — so a rename at one site would fall through the generic render branch with no signal. They are now a frozen RULE_IDS constant referenced from both. No string value changed; the advisory remains byte-identical across all six proof payloads.

GSD Core documentation
Documentation is organised into four quadrants: tutorials help you learn by doing, how-to guides solve specific tasks, reference states authoritative facts, and explanation explores concepts and design decisions.
Language versions: English · Português (pt-BR) · 日本語 · 简体中文
Tutorials
- Your first project — install to first shipped phase, one guaranteed path
- Onboarding an existing codebase — bring GSD Core to a brownfield repo
- Build your first capability — author a tiny declarative capability and watch it act in the loop
- Install your first capability — install a third-party capability end-to-end: consent, verify, check for updates, remove
How-to guides
- Install on your runtime — runtime-specific install steps for all 16 supported runtimes
- Install a minimal GSD and add skills later — install only the core skills, then grow the surface with profiles and
/gsd-surface - Attach a plugin-provided skill to a GSD agent — use the
global:plugin:skillentry form to load Claude Code plugin skills into agent prompts - Discuss a phase — capture implementation decisions before planning begins
- Resolve edge-coverage findings — turn the spec phase's surfaced domain-boundary edges into covered, dismissed, or backstopped spec decisions
- Resolve prohibition findings — turn the spec phase's surfaced must-NOT constraints into resolved, dismissed, or deferred spec decisions
- Resolve an ESLint glob-coverage finding — bring a source file that matches no lint rule under coverage, or record a reasoned exemption
- Plan a phase — run research, decompose work, and verify plan quality
- Execute a phase — run plans in parallel waves with fresh-context subagents
- Verify and ship — walk through completed work, diagnose failures, and create the PR
- Catch complexity before it compounds — enable the post-execute refactor hook, read a proposal's score vs. anchor delta, and accept or decline it
- Run phases autonomously — use autonomous mode for unattended phase execution
- Handle quick and fast tasks — use
/gsd-quickand/gsd-fastfor ad-hoc work outside the phase loop - Configure model profiles — switch between quality, balanced, and budget model tiers
- Control which host runtime GSD reports — read the
agent_runtimeladder, understand what host detection looks at, and pin the runtime when detection is not what you want - Set up cross-AI review — configure a second AI to review code produced by the primary agent
- Work in parallel with workstreams — run independent lines of work simultaneously using workstreams
- Isolate work with workspaces — use workspaces to sandbox experimental or risky changes
- Debug a failed execution — diagnose and recover from broken or incomplete phase execution
- Interpret scope-conformance warnings — read the advisory the worktree-wave merge emits when a plan branch commits outside its declared scope
- Interpret install-shadow warnings — read the advisory GSD Core emits when a
/gsd-*trigger is installed at both scopes and one silently wins, and tell "nothing to report" apart from "could not look" - Interpret
state validateresults — read thescopereason codes and tell "nothing to report" apart from "could not look" - Spike and sketch — use
/gsd-spikeand/gsd-sketchfor exploratory work before committing to a plan - Design a UI phase — use the UI phase loop for frontend and visual work
- Develop a Capability for GSD 1.5+ — add feature Capabilities, hook fragments, and registry entries
- Ship a reviewer lane in your capability — declare a
reviewerbody so/gsd-reviewdiscovers, invokes, and renders your external review CLI or model endpoint - List your reviewer lane in the registry — publish a lane you have built to the Reviewer Lane Registry so other people can find and install it
- Take over a capability or EoS integration — assume maintainership of an existing third-party capability, reviewer lane, or EoS host integration through a handoff, an adoption fork, first-party absorption, or a de-listing
- Add or update a host's integration — set a host's documentation-sourced
runtime.hostIntegrationaxes (ADR-1239 Phase A), with theundocumentedsentinel rule - Turn a capability off (and keep it off) — disable a capability via the surface, or gate individual hooks off without removing the capability
- Drive GSD from a tracker issue — start a phase from a GitHub, Linear, or Jira issue
- Migrate from GSD 2 — upgrade an existing GSD 2 project to GSD Core
- Update GSD — re-run the installer to pick up the latest release

Explanation
- Context engineering — how context rot forms and how GSD Core prevents it
- The phase loop — design rationale for the Discuss → Plan → Execute → Verify → Ship cycle
- Multi-agent orchestration — how subagents are spawned, scoped, and coordinated
- Security model — trust boundaries, permissions, and safe automation
- The capability trust model — why third-party capabilities are gated by consent + integrity + reversibility, not a sandbox
