pre-edit-governance
Skill4 starsChanged 13 days agoApache-2.0View on GitHub
Use before an AI coding agent modifies code, or whenever someone asks whether a planned change is safe to make. This is the mandatory checkpoint that runs first: in one call Garuda returns the target's caller fan-in, its criticality tier, the active YAML policies that apply, and the MUST and MUST NOT rules from ADRs and agent instruction files. It also flags metrics or calculations with competing implementations across teams and any surface frozen against unreviewed edits. The result is a proceed, revise or escalate decision, so the agent knows what to respect, or when to ask a human, before writing any code. Read-only by default.

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

03 — Garuda Pre-Edit Governance Gate
Acts as the mandatory pre-change checkpoint before an AI coding agent modifies code, returning a proceed, revise, or escalate decision.
1. Purpose & Triggers
Invoke this skill when the user or coding workflow asks:
- "Before modifying this code, check Garuda's policies"
- "Run pre-edit governance for my planned change"
- "Can an AI agent safely edit this package?"
2. Required Context
workspace: Target Garuda workspace name (default:"default").repo_dir: Repository root path (default:".").diff/target: Git revision range (e.g."HEAD") or symbol/package name.
3. Ordered MCP Workflow
garuda.preflight_bundle(orgaruda.talon_pre_edit) — Fetch caller fan-in, package criticality tier, active YAML policies, and applicableMUST/MUST_NOTADR claims in one call.garuda.disambiguate_logic— If the target symbol implements a domain metric or calculation, check for competing cross-team variants (0.0–1.0weights) andFROZEN_SEVERE_DO_NOT_TOUCHlocks.- Evaluate whether the target surface is
HIGH_SEVEREor governed by aBLOCKpolicy before writing code.
CLI Fallback (when MCP stdio is not attached):
garuda talon brief <SymbolOrFile> && garuda audit criticality4. Decision & Epistemic Rules
- Epistemic States: Always distinguish
SUPPORTED(backed by compiler/AST + runtime evidence where required),UNVERIFIED(statically extracted, awaiting runtime trace), andCONTRADICTED(violates ADR, policy, or static boundary). - Governance Verdicts:
ALLOW(proceed),WARN(proceed with note),REVIEW(requires human architectural review),BLOCK(halt and remediate net-new violation),INCONCLUSIVE(0 entities matched policy scope; never treat as vacuousALLOW).
5. Output Contract
Format every report using this six-part structure:
Finding -> Evidence (file:line & match_method) -> Affected Components (callers & tier) -> Policy / ADR -> Confidence / Status -> Recommended Action
6. Safety & Limitations
- Read-Only by Default: Public installations run with
GARUDA_MCP_READ_ONLY=true. Never invoke mutating tools (garuda.approve_base_rulebook,garuda.decide_logic_variant,garuda.reconcile_data_audit) without explicit human authorization (GARUDA_MCP_APPROVER). - Scope Qualification: RFC 6962 Merkle proofs (
H_leaf = SHA256(0x00 || data)) establish tamper-evident integrity and inclusion of recorded governance evaluations; they do not replace unit, integration, or dynamic security testing.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
