§1 Gemini integration

ADLC for Google Gemini

Advisory PreToolUse rails-guard for agy, plus skills and a prosecutor agent. The unbypassable CI rail-freeze gate is the real control. In-session rails are advisory. agy fails open on hook failure, so CI is the guarantee, not an optional extra.

Global npm & npx installCI is the backstop

hooks: 4
skills: 4
commands: 5
prosecutor agents: 7

Local plugin install

install: Google Gemini (Antigravity & JetSki)

(cd "$(mktemp -d)" && npx --package=@adlc/gemini adlc-gemini install)
npm install -g @adlc/gemini
adlc-gemini install

Recommended: (cd "$(mktemp -d)" && npx --package=@adlc/gemini adlc-gemini install) — it fetches the package and registers it with agy. Export ADLC_P4_ENFORCEMENT=1 with an active ticket.

§2 Native surfaces

What the Antigravity plugin installs

01 / hooks

PreToolUse, PostToolUse, PreInvocation, and Stop lifecycle hooks

The PreToolUse hook denies frozen rail edits in-session. PostToolUse authenticates executed tool results and transcript hashes, PreInvocation injects active ticket context, and Stop intercepts unverified completion.

02 / skills

Four skills around the adlc CLIs

Skills wrap the adlc CLIs from triage through distill. The hook only covers the rail moment.

adlc
adlc-doctrine
adlc-prosecutor
adlc-self-orchestrate

03 / commands

Commands for bootstrap, planning, and diagnostics

/adlc-init scaffolds the repo, /adlc-plan compiles brain plans, /adlc-prosecute fans out multi-lens review, /adlc-status inspects context, and /adlc-doctor verifies health.

04 / prosecutor agents

Five lenses, main prosecutor, and verifier

P5 prosecution fans out five specialist lenses, dedupes findings via main prosecutor, and verifies with an independent verifier.

prosecutor-contract
prosecutor-correctness
prosecutor-diff
prosecutor-security
prosecutor-tests
prosecutor-verifier

§3 Phase routing

Skills route, CI enforces

Skills and commands route work. The hook is only an in-session nudge. Treat CI as required before you rely on this integration for enforcement.

Phase	Antigravity entry	Evidence produced
P0	/adlc-init · adlc-ticket	ticket in .adlc/tickets.json
P1-P2	adlc CLI via skills	spec-lint · premortem · coldstart
P3-P4	PreToolUse + CI	advisory deny · rails-guard-ci
P5-P6	prosecutor agent	hollow-test · behavior-diff · manifest
P7	adlc skills	foundry · rejection mining

§4 Frozen rails

Advisory in session, required in CI

In the session

Advisory deny, fail-open on hook failure

Advisory deny with fail-open on hook failure. POSIX-oriented command paths; Windows in-session is unsupported. Shell writes are not gated. Do not treat the hook as a hard block.

In CI

Unbypassable control across platforms

scripts/rails-guard-ci.mjs is the guarantee for every platform, including Windows. Make docs/ci/rails-guard.yml a required check (or fold it into an existing required job on free private repos).

§5 Install
