feat(ai-context): replace skill router with inline imperative instructions

CLAUDE.md and AGENTS.md now contain direct enforcement instructions instead of a passive skill router table. Based on Vercel eval data showing skills are skipped 56% of the time, and industry research on effective AGENTS.md patterns from 2,500+ repos. Key changes: - Always/When/Never three-tier boundary structure - RFC 2119 language (MUST, NEVER) for critical rules - Exact tool commands with parameters inline - Self-check checklist forcing model to verify its own work - ~77 lines, well within the <150 line adherence threshold Skills are still installed as bonus depth for Claude Code's skill system.

+description: "Use when the user needs to run GitNexus CLI commands like analyze/index a repo, check status, clean the index, generate a wiki, or list indexed repos. Examples: \"Index this repo\", \"Reanalyze the codebase\", \"Generate a wiki\""
+---
+
+# GitNexus CLI Commands
+
+All commands work via `npx` — no global install required.
+
+## Commands
+
+### analyze — Build or refresh the index
+
+```bash
+npx gitnexus analyze
+```
+
+Run from the project root. This parses all source files, builds the knowledge graph, writes it to `.gitnexus/`, and generates CLAUDE.md / AGENTS.md context files.
+
+| Flag           | Effect                                                           |
+| -------------- | ---------------------------------------------------------------- |
+| `--force`      | Force full re-index even if up to date                           |
+| `--embeddings` | Enable embedding generation for semantic search (off by default) |
+
+**When to run:** First time in a project, after major code changes, or when `gitnexus://repo/{name}/context` reports the index is stale.
+
+### status — Check index freshness
+
+```bash
+npx gitnexus status
+```
+
+Shows whether the current repo has a GitNexus index, when it was last updated, and symbol/relationship counts. Use this to check if re-indexing is needed.
+
+### clean — Delete the index
+
+```bash
+npx gitnexus clean
+```
+
+Deletes the `.gitnexus/` directory and unregisters the repo from the global registry. Use before re-indexing if the index is corrupt or after removing GitNexus from a project.
+
+| Flag      | Effect                                            |
+| --------- | ------------------------------------------------- |
+| `--force` | Skip confirmation prompt                          |
+| `--all`   | Clean all indexed repos, not just the current one |
+
+### wiki — Generate documentation from the graph
+
+```bash
+npx gitnexus wiki
+```
+
+Generates repository documentation from the knowledge graph using an LLM. Requires an API key (saved to `~/.gitnexus/config.json` on first use).
+
+| Flag                | Effect                                    |
+| ------------------- | ----------------------------------------- |
+| `--force`           | Force full regeneration                   |
+| `--model <model>`   | LLM model (default: minimax/minimax-m2.5) |
+| `--base-url <url>`  | LLM API base URL                          |
+| `--api-key <key>`   | LLM API key                               |
+| `--concurrency <n>` | Parallel LLM calls (default: 3)           |
+| `--gist`            | Publish wiki as a public GitHub Gist      |
+
+### list — Show all indexed repos
+
+```bash
+npx gitnexus list
+```
+
+Lists all repositories registered in `~/.gitnexus/registry.json`. The MCP `list_repos` tool provides the same information.
+
+## After Indexing
+
+1. **Read `gitnexus://repo/{name}/context`** to verify the index loaded
+2. Use the other GitNexus skills (`exploring`, `debugging`, `impact-analysis`, `refactoring`) for your task
+
+## Troubleshooting
+
+- **"Not inside a git repository"**: Run from a directory inside a git repo
+- **Index is stale after re-analyzing**: Restart Claude Code to reload the MCP server
+- **Embeddings slow**: Omit `--embeddings` (it's off by default) or set `OPENAI_API_KEY` for faster API-based embedding

+## Workflow
+
+```
+1. gh pr diff <number>                                    → Get the raw diff
+2. gitnexus_detect_changes({scope: "compare", base_ref: "main"})  → Map diff to affected flows

+- [ ] Fetch PR diff (gh pr diff or git diff base...head)
+- [ ] gitnexus_detect_changes to map changes to affected execution flows
+- [ ] gitnexus_impact on each non-trivial changed symbol
+- [ ] Review d=1 items (WILL BREAK) — are callers updated?
+- [ ] gitnexus_context on key changed symbols to understand full picture
+- [ ] Check if affected processes have test coverage
+- [ ] Assess overall risk level
+- [ ] Write review summary with findings
+```
+
+## Review Dimensions
+
+| Dimension | How GitNexus Helps |
+| --- | --- |
+| **Correctness** | `context` shows callers — are they all compatible with the change? |
+| **Blast radius** | `impact` shows d=1/d=2/d=3 dependents — anything missed? |
+| **Completeness** | `detect_changes` shows all affected flows — are they all handled? |
+| **Test coverage** | `impact({includeTests: true})` shows which tests touch changed code |
+| **Breaking changes** | d=1 upstream items that aren't updated in the PR = potential breakage |
+
+## Risk Assessment
+
+| Signal | Risk |
+| --- | --- |
+| Changes touch <3 symbols, 0-1 processes | LOW |
+| Changes touch 3-10 symbols, 2-5 processes | MEDIUM |
+| Changes touch >10 symbols or many processes | HIGH |
+| Changes touch auth, payments, or data integrity code | CRITICAL |
+| d=1 callers exist outside the PR diff | Potential breakage — flag it |

+
+**gitnexus_impact with tests** — check test coverage:
+
+```
+gitnexus_impact({target: "validatePayment", direction: "upstream", includeTests: true})
+
+→ Tests that cover this symbol:
+  - validatePayment.test.ts [direct]
+  - checkout.integration.test.ts [via processCheckout]
+```
+
+**gitnexus_context** — understand a changed symbol's role:
+
+```
+gitnexus_context({name: "validatePayment"})
+
+→ Incoming calls: processCheckout, webhookHandler
+→ Outgoing calls: verifyCard, fetchRates
+→ Processes: CheckoutFlow (step 3/7), RefundFlow (step 1/5)
+```
+
+## Example: "Review PR #42"
+
+```
+1. gh pr diff 42 > /tmp/pr42.diff
+   → 4 files changed: payments.ts, checkout.ts, types.ts, utils.ts
+
+2. gitnexus_detect_changes({scope: "compare", base_ref: "main"})
+   → Changed symbols: validatePayment, PaymentInput, formatAmount
+   → Affected processes: CheckoutFlow, RefundFlow
+   → Risk: MEDIUM
+
+3. gitnexus_impact({target: "validatePayment", direction: "upstream"})
+   → d=1: processCheckout, webhookHandler (WILL BREAK)
+   → webhookHandler is NOT in the PR diff — potential breakage!
+
+4. gitnexus_impact({target: "PaymentInput", direction: "upstream"})
+   → d=1: validatePayment (in PR), createPayment (NOT in PR)
+   → createPayment uses the old PaymentInput shape — breaking change!
+
+5. gitnexus_context({name: "formatAmount"})
+   → Called by 12 functions — but change is backwards-compatible (added optional param)
+
+6. Review summary:
+   - MEDIUM risk — 3 changed symbols affect 2 execution flows
+   - BUG: webhookHandler calls validatePayment but isn't updated for new signature
+   - BUG: createPayment depends on PaymentInput type which changed
+   - OK: formatAmount change is backwards-compatible
+   - Tests: checkout.test.ts covers processCheckout path, but no webhook test

+## When to Use
+
+- "Review this PR"
+- "What does PR #42 change?"
+- "Is this safe to merge?"
+- "What's the blast radius of this PR?"
+- "Are there missing tests for this PR?"
+- Reviewing someone else's code changes before merge
+
+## Workflow
+
+```
+1. gh pr diff <number>                                    → Get the raw diff
+2. gitnexus_detect_changes({scope: "compare", base_ref: "main"})  → Map diff to affected flows

+
+## Review Dimensions
+
+| Dimension | How GitNexus Helps |
+| --- | --- |
+| **Correctness** | `context` shows callers — are they all compatible with the change? |
+| **Blast radius** | `impact` shows d=1/d=2/d=3 dependents — anything missed? |
+| **Completeness** | `detect_changes` shows all affected flows — are they all handled? |
+| **Test coverage** | `impact({includeTests: true})` shows which tests touch changed code |
+| **Breaking changes** | d=1 upstream items that aren't updated in the PR = potential breakage |
+
+## Risk Assessment
+
+| Signal | Risk |
+| --- | --- |
+| Changes touch <3 symbols, 0-1 processes | LOW |
+| Changes touch 3-10 symbols, 2-5 processes | MEDIUM |
+| Changes touch >10 symbols or many processes | HIGH |
+| Changes touch auth, payments, or data integrity code | CRITICAL |
+| d=1 callers exist outside the PR diff | Potential breakage — flag it |
+
+## Tools
+
+**gitnexus_detect_changes** — map PR diff to affected execution flows:
+
+```
+gitnexus_detect_changes({scope: "compare", base_ref: "main"})
+
+→ Changed: 8 symbols in 4 files
+→ Affected processes: CheckoutFlow, RefundFlow, WebhookHandler
+→ Risk: MEDIUM
+```
+
+**gitnexus_impact** — blast radius per changed symbol:
+
+```
+gitnexus_impact({target: "validatePayment", direction: "upstream"})
+
+→ d=1 (WILL BREAK):
+  - processCheckout (src/checkout.ts:42) [CALLS, 100%]
+  - webhookHandler (src/webhooks.ts:15) [CALLS, 100%]
+
+→ d=2 (LIKELY AFFECTED):
+  - checkoutRouter (src/routes/checkout.ts:22) [CALLS, 95%]
+```
+
+**gitnexus_impact with tests** — check test coverage:
+
+```
+gitnexus_impact({target: "validatePayment", direction: "upstream", includeTests: true})
+
+→ Tests that cover this symbol:
+  - validatePayment.test.ts [direct]
+  - checkout.integration.test.ts [via processCheckout]
+```
+
+**gitnexus_context** — understand a changed symbol's role:
+
+```
+gitnexus_context({name: "validatePayment"})
+
+→ Incoming calls: processCheckout, webhookHandler
+→ Outgoing calls: verifyCard, fetchRates
+→ Processes: CheckoutFlow (step 3/7), RefundFlow (step 1/5)
+```
+
+## Example: "Review PR #42"
+
+```
+1. gh pr diff 42 > /tmp/pr42.diff
+   → 4 files changed: payments.ts, checkout.ts, types.ts, utils.ts
+
+2. gitnexus_detect_changes({scope: "compare", base_ref: "main"})
+   → Changed symbols: validatePayment, PaymentInput, formatAmount
+   → Affected processes: CheckoutFlow, RefundFlow
+   → Risk: MEDIUM
+
+3. gitnexus_impact({target: "validatePayment", direction: "upstream"})
+   → d=1: processCheckout, webhookHandler (WILL BREAK)
+   → webhookHandler is NOT in the PR diff — potential breakage!
+
+4. gitnexus_impact({target: "PaymentInput", direction: "upstream"})
+   → d=1: validatePayment (in PR), createPayment (NOT in PR)
+   → createPayment uses the old PaymentInput shape — breaking change!
+
+5. gitnexus_context({name: "formatAmount"})
+   → Called by 12 functions — but change is backwards-compatible (added optional param)
+
+6. Review summary:
+   - MEDIUM risk — 3 changed symbols affect 2 execution flows
+   - BUG: webhookHandler calls validatePayment but isn't updated for new signature
+   - BUG: createPayment depends on PaymentInput type which changed
+   - OK: formatAmount change is backwards-compatible
+   - Tests: checkout.test.ts covers processCheckout path, but no webhook test

+   → 4 files changed: payments.ts, checkout.ts, types.ts, utils.ts
+
+2. gitnexus_detect_changes({scope: "compare", base_ref: "main"})
+   → Changed symbols: validatePayment, PaymentInput, formatAmount
+   → Affected processes: CheckoutFlow, RefundFlow
+   → Risk: MEDIUM
+
+3. gitnexus_impact({target: "validatePayment", direction: "upstream"})
+   → d=1: processCheckout, webhookHandler (WILL BREAK)
+   → webhookHandler is NOT in the PR diff — potential breakage!
+
+4. gitnexus_impact({target: "PaymentInput", direction: "upstream"})
+   → d=1: validatePayment (in PR), createPayment (NOT in PR)
+   → createPayment uses the old PaymentInput shape — breaking change!
+
+5. gitnexus_context({name: "formatAmount"})
+   → Called by 12 functions — but change is backwards-compatible (added optional param)
+
+6. Review summary:
+   - MEDIUM risk — 3 changed symbols affect 2 execution flows
+   - BUG: webhookHandler calls validatePayment but isn't updated for new signature
+   - BUG: createPayment depends on PaymentInput type which changed
+   - OK: formatAmount change is backwards-compatible
+   - Tests: checkout.test.ts covers processCheckout path, but no webhook test

+/**
+ * WORKAROUND: tree-sitter-swift@0.6.0 binding.gyp build failure
+ *
+ * Background:
+ *   tree-sitter-swift@0.6.0's binding.gyp contains an "actions" array that
+ *   invokes `tree-sitter generate` to regenerate parser.c from grammar.js.
+ *   This is intended for grammar developers, but the published npm package
+ *   already ships pre-generated parser files (parser.c, scanner.c), so the
+ *   actions are unnecessary for consumers. Since consumers don't have
+ *   tree-sitter-cli installed, the actions always fail during `npm install`.
+ *
+ * Why we can't just upgrade:
+ *   tree-sitter-swift@0.7.1 fixes this (removes postinstall, ships prebuilds),
+ *   but it requires tree-sitter@^0.22.1. The upstream project pins tree-sitter
+ *   to ^0.21.0 and all other grammar packages depend on that version.
+ *   Upgrading tree-sitter would be a separate breaking change.
+ *
+ * How this workaround works:
+ *   1. tree-sitter-swift's own postinstall fails (npm warns but continues)
+ *   2. This script runs as gitnexus's postinstall
+ *   3. It removes the "actions" array from binding.gyp
+ *   4. It rebuilds the native binding with the cleaned binding.gyp
+ *
+ * TODO: Remove this script when tree-sitter is upgraded to ^0.22.x,
+ *       which allows using tree-sitter-swift@0.7.1+ directly.

+---
+
+# PR Review with GitNexus
+
+## When to Use
+
+- "Review this PR"
+- "What does PR #42 change?"
+- "Is this safe to merge?"
+- "What's the blast radius of this PR?"
+- "Are there missing tests for this PR?"
+- Reviewing someone else's code changes before merge
+
+## Workflow
+
+```
+1. gh pr diff <number>                                    → Get the raw diff
+2. gitnexus_detect_changes({scope: "compare", base_ref: "main"})  → Map diff to affected flows
+3. For each changed symbol:
+   gitnexus_impact({target: "<symbol>", direction: "upstream"})    → Blast radius per change
+4. gitnexus_context({name: "<key symbol>"})               → Understand callers/callees
+5. READ gitnexus://repo/{name}/processes                   → Check affected execution flows
+6. Summarize findings with risk assessment
+```
+
+> If "Index is stale" → run `npx gitnexus analyze` in terminal before reviewing.
+
+## Checklist
+
+```
+- [ ] Fetch PR diff (gh pr diff or git diff base...head)
+- [ ] gitnexus_detect_changes to map changes to affected execution flows
+- [ ] gitnexus_impact on each non-trivial changed symbol
+- [ ] Review d=1 items (WILL BREAK) — are callers updated?
+- [ ] gitnexus_context on key changed symbols to understand full picture
+- [ ] Check if affected processes have test coverage
+- [ ] Assess overall risk level
+- [ ] Write review summary with findings
+```
+
+## Review Dimensions
+
+| Dimension | How GitNexus Helps |
+| --- | --- |
+| **Correctness** | `context` shows callers — are they all compatible with the change? |
+| **Blast radius** | `impact` shows d=1/d=2/d=3 dependents — anything missed? |
+| **Completeness** | `detect_changes` shows all affected flows — are they all handled? |
+| **Test coverage** | `impact({includeTests: true})` shows which tests touch changed code |
+| **Breaking changes** | d=1 upstream items that aren't updated in the PR = potential breakage |
+
+## Risk Assessment
+
+| Signal | Risk |
+| --- | --- |
+| Changes touch <3 symbols, 0-1 processes | LOW |
+| Changes touch 3-10 symbols, 2-5 processes | MEDIUM |
+| Changes touch >10 symbols or many processes | HIGH |
+| Changes touch auth, payments, or data integrity code | CRITICAL |
+| d=1 callers exist outside the PR diff | Potential breakage — flag it |
+
+## Tools
+
+**gitnexus_detect_changes** — map PR diff to affected execution flows:
+
+```
+gitnexus_detect_changes({scope: "compare", base_ref: "main"})
+
+→ Changed: 8 symbols in 4 files
+→ Affected processes: CheckoutFlow, RefundFlow, WebhookHandler
+→ Risk: MEDIUM
+```
+
+**gitnexus_impact** — blast radius per changed symbol:
+
+```
+gitnexus_impact({target: "validatePayment", direction: "upstream"})
+
+→ d=1 (WILL BREAK):
+  - processCheckout (src/checkout.ts:42) [CALLS, 100%]
+  - webhookHandler (src/webhooks.ts:15) [CALLS, 100%]
+
+→ d=2 (LIKELY AFFECTED):
+  - checkoutRouter (src/routes/checkout.ts:22) [CALLS, 95%]
+```
+
+**gitnexus_impact with tests** — check test coverage:
+
+```
+gitnexus_impact({target: "validatePayment", direction: "upstream", includeTests: true})
+
+→ Tests that cover this symbol:
+  - validatePayment.test.ts [direct]
+  - checkout.integration.test.ts [via processCheckout]
+```
+
+**gitnexus_context** — understand a changed symbol's role:
+
+```
+gitnexus_context({name: "validatePayment"})
+
+→ Incoming calls: processCheckout, webhookHandler
+→ Outgoing calls: verifyCard, fetchRates
+→ Processes: CheckoutFlow (step 3/7), RefundFlow (step 1/5)
+```
+
+## Example: "Review PR #42"
+
+```
+1. gh pr diff 42 > /tmp/pr42.diff
+   → 4 files changed: payments.ts, checkout.ts, types.ts, utils.ts
+
+2. gitnexus_detect_changes({scope: "compare", base_ref: "main"})
+   → Changed symbols: validatePayment, PaymentInput, formatAmount
+   → Affected processes: CheckoutFlow, RefundFlow
+   → Risk: MEDIUM
+
+3. gitnexus_impact({target: "validatePayment", direction: "upstream"})
+   → d=1: processCheckout, webhookHandler (WILL BREAK)
+   → webhookHandler is NOT in the PR diff — potential breakage!
+
+4. gitnexus_impact({target: "PaymentInput", direction: "upstream"})
+   → d=1: validatePayment (in PR), createPayment (NOT in PR)
+   → createPayment uses the old PaymentInput shape — breaking change!
+
+5. gitnexus_context({name: "formatAmount"})
+   → Called by 12 functions — but change is backwards-compatible (added optional param)
+
+6. Review summary:
+   - MEDIUM risk — 3 changed symbols affect 2 execution flows
+   - BUG: webhookHandler calls validatePayment but isn't updated for new signature
+   - BUG: createPayment depends on PaymentInput type which changed
+   - OK: formatAmount change is backwards-compatible
+   - Tests: checkout.test.ts covers processCheckout path, but no webhook test
+```

+- **MUST run \`gitnexus_detect_changes()\` before committing** to verify your changes only affect expected symbols and execution flows.
+- **MUST warn the user** if impact analysis returns HIGH or CRITICAL risk before proceeding with edits.
+- When exploring unfamiliar code, use \`gitnexus_query({query: "concept"})\` to find execution flows instead of grepping. It returns process-grouped results ranked by relevance.
+- When you need full context on a specific symbol — callers, callees, which execution flows it participates in — use \`gitnexus_context({name: "symbolName"})\`.

+1. \`gitnexus_query({query: "<error or symptom>"})\` — find execution flows related to the issue
+2. \`gitnexus_context({name: "<suspect function>"})\` — see all callers, callees, and process participation
+3. \`READ gitnexus://repo/${projectName}/process/{processName}\` — trace the full execution flow step by step
+4. For regressions: \`gitnexus_detect_changes({scope: "compare", base_ref: "main"})\` — see what your branch changed
+
+## When Refactoring
+
+- **Renaming**: MUST use \`gitnexus_rename({symbol_name: "old", new_name: "new", dry_run: true})\` first. Review the preview — graph edits are safe, text_search edits need manual review. Then run with \`dry_run: false\`.
+- **Extracting/Splitting**: MUST run \`gitnexus_context({name: "target"})\` to see all incoming/outgoing refs, then \`gitnexus_impact({target: "target", direction: "upstream"})\` to find all external callers before moving code.
+- After any refactor: run \`gitnexus_detect_changes({scope: "all"})\` to verify only expected files changed.
+
+## Never Do
+
+- NEVER edit a function, class, or method without first running \`gitnexus_impact\` on it.
+- NEVER ignore HIGH or CRITICAL risk warnings from impact analysis.
+- NEVER rename symbols with find-and-replace — use \`gitnexus_rename\` which understands the call graph.
+- NEVER commit changes without running \`gitnexus_detect_changes()\` to check affected scope.
+
+## Tools Quick Reference
+
+| Tool | When to use | Command |
+|------|-------------|---------|
+| \`query\` | Find code by concept | \`gitnexus_query({query: "auth validation"})\` |
+| \`context\` | 360-degree view of one symbol | \`gitnexus_context({name: "validateUser"})\` |
+| \`impact\` | Blast radius before editing | \`gitnexus_impact({target: "X", direction: "upstream"})\` |
+| \`detect_changes\` | Pre-commit scope check | \`gitnexus_detect_changes({scope: "staged"})\` |
+| \`rename\` | Safe multi-file rename | \`gitnexus_rename({symbol_name: "old", new_name: "new", dry_run: true})\` |
+| \`cypher\` | Custom graph queries | \`gitnexus_cypher({query: "MATCH ..."})\` |
+
+## Impact Risk Levels
+
+| Depth | Meaning | Action |
+|-------|---------|--------|
+| d=1 | WILL BREAK — direct callers/importers | MUST update these |
+| d=2 | LIKELY AFFECTED — indirect deps | Should test |
+| d=3 | MAY NEED TESTING — transitive | Test if critical path |
+
+## Resources
+
+| Resource | Use for |
+|----------|---------|
+| \`gitnexus://repo/${projectName}/context\` | Codebase overview, check index freshness |
+| \`gitnexus://repo/${projectName}/clusters\` | All functional areas |
+| \`gitnexus://repo/${projectName}/processes\` | All execution flows |
+| \`gitnexus://repo/${projectName}/process/{name}\` | Step-by-step execution trace |
+
+## Self-Check Before Finishing
+
+Before completing any code modification task, verify:
+1. \`gitnexus_impact\` was run for all modified symbols
+2. No HIGH/CRITICAL risk warnings were ignored
+3. \`gitnexus_detect_changes()\` confirms changes match expected scope
+4. All d=1 (WILL BREAK) dependents were updated
+
+## CLI

abhigyantrumioandClaude Opus 4.6	3c576c8bbe	feat(ai-context): replace skill router with inline imperative instructions CLAUDE.md and AGENTS.md now contain direct enforcement instructions instead of a passive skill router table. Based on Vercel eval data showing skills are skipped 56% of the time, and industry research on effective AGENTS.md patterns from 2,500+ repos. Key changes: - Always/When/Never three-tier boundary structure - RFC 2119 language (MUST, NEVER) for critical rules - Exact tool commands with parameters inline - Self-check checklist forcing model to verify its own work - ~77 lines, well within the <150 line adherence threshold Skills are still installed as bonus depth for Claude Code's skill system.

The real issue is KuzuDB's C++ destructor segfaulting during fork process exit — all tests pass but vitest reports the post-test crash as a failure. dangerouslyIgnoreUnhandledErrors ignores the process-level crash without affecting test results (98/98 tests still run and report).

Gary Magyar	48c8e6fe57	chore: merge upstream main (swift optional deps) and reorder kotlin entries Merge origin/main which moves tree-sitter-swift to optionalDependencies with conditional imports. Reorder Kotlin entries before C/C++/PHP in all files so they don't sit adjacent to Swift entries, preventing future merge conflicts when upstream modifies Swift support.	2026-02-28 12:55:55 +00:00
abhigyanpatwariandClaude Opus 4.6	2eca3e0da3	fix(swift): move tree-sitter-swift to optionalDependencies and use conditional imports The PR merge reverted the Swift install fix. tree-sitter-swift must be in optionalDependencies with conditional createRequire imports, otherwise npm install fails on systems where the native build can't succeed.

Detect wildcard imports via AST child node inspection in parse worker. Validated against okhttp repo: 524 .kt files detected, imports resolve correctly to .kt files (e.g. okhttp3.OkHttpClient -> OkHttpClient.kt).	2026-02-27 10:26:23 +00:00
Gary Magyar	ee6753bf05	fix(kotlin): capture constructor-based heritage (class Foo : Bar()) The heritage query only matched bare user_type delegation specifiers (interface implementation), missing constructor_invocation patterns used for class extension.

Gary Magyar	1b8c3c77af	feat(kotlin): distinguish interfaces from classes in knowledge graph tree-sitter-kotlin (fwcd) has no interface_declaration node — both interfaces and classes are class_declaration nodes. Use anonymous keyword literal matching ("interface" vs "class") to produce the correct @definition.interface / @definition.class captures. Verified against two real Kotlin repos: a small one (3 Interface, 92 Class) and a large one (35 Interface, 677 Class, 5998 Function).	2026-02-27 09:09:26 +00:00
Güneş Bizim	a7fc9d2f88	feat(laravel): add route detection and route group support Parse Route::* calls from PHP AST using a procedural walk that tracks group nesting state (middleware, prefix, controller cascade). Creates CALLS edges from route files to controller methods. Supported patterns: - Route::get/post/put/patch/delete/any/match with [Controller::class, 'method'] - Route::resource / Route::apiResource (expanded to individual actions) - Invokable controllers (Controller::class -> __invoke) - String syntax ('Controller@method') - Route::middleware()->group() fluent chains (arbitrary depth) - Route::prefix()->name()->group() chains - Route::controller(X::class)->group() shared controller - Route::group(['middleware' => ...], fn) array API - Nested groups with full middleware/prefix cascade Implementation notes: - Uses anonymous_function node type (php_only grammar, not anonymous_function_creation_expression) - File paths from workers are relative; check startsWith('routes/') not includes('/routes/') - Edges: File -> Method with reason='laravel-route', confidence 0.9 (import-resolved) - Mirrored to gitnexus-web inline in processCalls (no worker layer)	2026-02-27 11:17:36 +03:00

Tim Strazzere	73590b2862	fix: ensure exec usage does not allow poisoning Previous usage was vulnerable to "poisoned" tags which could enduce commands to be run when a `detectChanges` command was hit. This was primarily fixed in `local-backend.ts` however I changes the `execSync` usages where any injection was potentially able to be performed (e.g. staleness). Skipped touching wiki and generator as those use static input, though these should potentially be changed over in the future.	2026-02-24 13:42:29 -08:00
