| 1 | +# Guard Policies Evolution - Quick Start |
| 2 | + |
| 3 | +This branch evolves the experimental `lpcox/github-difc` branch's guard-policies implementation to be compatible with the main branch format. |
| 4 | + |
| 5 | +## β
Status: Complete and Ready for Rebase |
| 6 | + |
| 7 | +All work is complete. The `lpcox/github-difc` branch can now be rebased onto main without guard-policies configuration conflicts. |
| 8 | + |

Added validation for guard policies in both JSON stdin and TOML file configs |
| 19 | +4. β
All tests passing (13 guard-policies tests + 116+ config tests) |
| 20 | +5. β
Complete verification via `make agent-finished` |
| 21 | + |
| 22 | +## π Configuration Format |
| 23 | + |
| 24 | +### Main Branch Format (Now Supported) |
| 25 | + |
| 26 | +**TOML:** |
| 27 | +```toml |
| 28 | +[servers.github.guard_policies.github] |
| 29 | +repos = ["github/*", "myorg/repo"] |
| 30 | +min-integrity = "reader" |
| 31 | +``` |
| 32 | + |
| 33 | +**JSON:** |
| 34 | +```json |
| 35 | +{ |
| 36 | + "mcpServers": { |
| 37 | + "github": { |
| 38 | + "guard-policies": { |
| 39 | + "github": { |
| 40 | + "repos": ["github/*"], |
| 41 | + "min-integrity": "reader" |
| 42 | + } |
| 43 | + } |
| 44 | + } |
| 45 | + } |
| 46 | +} |
| 47 | +``` |
| 48 | + |
| 49 | +### Supported Values |
| 50 | + |
| 51 | +**repos:** |
| 52 | +- `"all"` - All repositories accessible by token |
| 53 | +- `"public"` - Public repositories only |
| 54 | +- `["owner/repo", "owner/*", "owner/prefix*"]` - Array of patterns |
| 55 | + |
| 56 | +**min-integrity:** |
| 57 | +- `"none"` - No integrity requirements |
| 58 | +- `"reader"` - Read-level integrity |
| 59 | +- `"writer"` - Write-level integrity |
| 60 | +- `"merged"` - Merged-level integrity |
| 61 | + |
| 62 | +## π Next Steps for Rebasing |
| 63 | + |
| 64 | +1. **Backup the experimental branch:** |
| 65 | + ```bash |
| 66 | + git checkout lpcox/github-difc |
| 67 | + git branch lpcox/github-difc-backup |
| 68 | + ``` |
| 69 | + |
| 70 | +2. **Rebase onto main:** |
| 71 | + ```bash |
| 72 | + git rebase main |
| 73 | + ``` |
| 74 | + |
| 75 | +3. **Resolve conflicts:** |
| 76 | + - For `internal/config/guard_policy.go`: Use the new implementation |
| 77 | + - For guard-policies configuration: Use main branch format |
| 78 | + - Decide on DIFC fields (EnableDIFC, DIFCMode) - keep or remove |
| 79 | + |
| 80 | +4. **Test:** |
| 81 | + ```bash |
| 82 | + make agent-finished |
| 83 | + ``` |
| 84 | + |
| 85 | +## π§ͺ Test Results |
| 86 | + |
| 87 | +``` |
| 88 | +β 13 guard-policies tests passing |
| 89 | +β 116+ config tests passing (20.5s) |
| 90 | +β All integration tests passing (40.4s) |
| 91 | +β Format checks passing |
| 92 | +β Build successful |
| 93 | +β Lint checks passing |
| 94 | +``` |
| 95 | + |
| 96 | +## π Files Modified |
| 97 | + |
| 98 | +**Created:** |
| 99 | +- `internal/config/guard_policy.go` - Guard policies validation for main format |
| 100 | +- `GUARD_POLICIES_MIGRATION_PLAN.md` - Detailed migration plan |
| 101 | +- `GUARD_POLICIES_EVOLUTION_SUMMARY.md` - Complete summary and strategy |
| 102 | +- `GUARD_POLICIES_EVOLUTION_README.md` - This file |
| 103 | + |
| 104 | +**Modified:** |
| 105 | +- `internal/config/config_stdin.go` - Added guard policies validation |
| 106 | +- `internal/config/config_core.go` - Added guard policies validation |
| 107 | + |
| 108 | +## π‘ Key Decisions |
| 109 | + |
| 110 | +When rebasing the experimental branch, you'll need to decide: |
| 111 | + |
| 112 | +### Option 1: Guard Policies Configuration Only |
| 113 | +- Keep only the guard-policies configuration support |
| 114 | +- Remove experimental DIFC features (EnableDIFC, DIFCMode, etc.) |
| 115 | +- Simpler integration, less to maintain |
| 116 | + |
| 117 | +### Option 2: Full DIFC Integration |
| 118 | +- Keep guard-policies configuration (done) |
| 119 | +- Preserve DIFC config fields |
| 120 | +- Update guard interface integration |
| 121 | +- Update server integration points |
| 122 | +- More comprehensive but requires additional work |
| 123 | + |
| 124 | +See [GUARD_POLICIES_EVOLUTION_SUMMARY.md](GUARD_POLICIES_EVOLUTION_SUMMARY.md) for detailed analysis of each option. |
| 125 | + |
| 126 | +## π Validation Features |
| 127 | + |
| 128 | +The implementation includes comprehensive validation: |
| 129 | + |
| 130 | +- β
Repository pattern validation (exact, wildcard, prefix) |
| 131 | +- β
Integrity level validation |
| 132 | +- β
Duplicate detection |
| 133 | +- β
Empty value checks |
| 134 | +- β
Owner/repo name character validation |
| 135 | +- β
Case-insensitive integrity values |
| 136 | +- β
Sorted and normalized output |
