# Hephaestus Stormbreaker Loop
Drive a goal through the **Stormbreaker Loop** — Hephaestus' force-robust,
verifier-first execution loop. Unlike a one-shot answer or a generic parallel
fan-out, Stormbreaker **routes the goal to real Agentlas specialists**, structures
the work as a dependency-ordered pipeline fabric, drives each work packet as a
**hardened goal loop** (it does not stall, run away, or claim false success), and
**refuses to report success without evidence**. Never guess an agent yourself when
this skill is active — the router or Hub decides the workforce.
## Core-owned Goal + UltraCode harness
Every `hep-storm` result includes `execution_harness`. Before planning or
executing any packet, apply `execution_harness.system_prompt` **verbatim** and
retain its `prompt_sha256` in the goal ledger. This adapter must never redefine,
summarize, or replace Goal mode or UltraCode mode with host-local wording. The
adapter owns invocation only; Agentlas Core owns the execution protocol.
If the host exposes live Codex, Claude Code, Gemini, local-model, or other
sessions, provide their JSON array through `AGENTLAS_SESSION_INVENTORY` or
`--session-inventory`. If it does not, accept Core's explicit `host:primary`
fallback; never invent a model ID or claim unavailable parallel workers.
With no external executor, the runner intentionally returns `status:
materialized` and `final_gate.can_report_success: false`. That is the host's
signal to execute the returned packets with its native tools; it is not a
failure and must never be rewritten as completion.
## 1. Resolve the runner
Run this resolution in a shell and use the first hit:
```bash
RUNNER=""
for c in \
"$HOME/.agentlas/runtime/current/bin/hephaestus" \
./bin/hephaestus
do [ -x "$c" ] && RUNNER="$c" && break; done
if [ -z "$RUNNER" ]; then
for cache in \
"$HOME/.claude/plugins/cache/agentlas-core-engine/hephaestus" \
"$HOME/.codex/plugins/cache/agentlas-core-engine/hephaestus"; do
newest="$(ls -d "$cache"/*/bin/hephaestus 2>/dev/null | sort -V | tail -1)"
[ -n "$newest" ] && [ -x "$newest" ] && RUNNER="$newest" && break
done
fi
```
If no runner exists, tell the user to run the one-touch installer:
`curl -fsSL https://raw.githubusercontent.com/agentlas-ai/Agentlas-OS/main/scripts/install-all-runtimes.sh | bash`
## 1.5 Core project first-contact contract
Every `hep-storm` call is a trusted plugin contact. Before routing or
materializing packets, Agentlas Core synchronously creates or repairs the
canonical private project soul memory, code map, ontology runtime, CareerGraph,
and merge-only `.gitignore` block for all of `.agentlas/`. A blocked bootstrap
receipt blocks the storm. The adapter must not substitute host-local files or a
second bootstrap implementation.
## 2. Agentlas sign-in
Before routing, ensure Agentlas is signed in:
```bash
if [ "${HEPHAESTUS_AUTH_AUTOPOPUP:-1}" != "0" ]; then
"$RUNNER" auth ensure --timeout 180 >/dev/null 2>&1 || true
fi
```
This opens the user's default browser only when there is no valid local
Agentlas sign-in yet. If a saved sign-in already exists, it silently reuses it.
For CI/headless checks only, set `HEPHAESTUS_AUTH_AUTOPOPUP=0` and skip this step.
## 3. Route and materialize the execution fabric
The Stormbreaker engine routes the goal and materializes a pipeline fabric
(packets, parallel groups, dependency gates, goal loops, a final gate, and a
resumable journal). In an agentic runtime **you are the executor** — the engine
gives you the verified plan; you carry it out with your own tools. No
`--executor-command`: the host model (you) executes each packet natively.
`--research-evidence` grounds plan/research packets with Research Engine receipts.
```bash
FABRIC="$("$RUNNER" hep-storm "<the user's goal>" --research-evidence --runtime "${AGENTLAS_HOST_RUNTIME:-agent-skills}")"
printf '%s\n' "$FABRIC"
```
## 4. Branch on the route decision
Read `route_decision.action` (or `route_action`) and branch — Stormbreaker only
auto-materializes a full fabric for a **pipeline**; other actions still start a
storm, just with the workforce the router chose:
- **`pipeline`** — the result carries the `execution_fabric` (`packets`,
`parallel_groups`, `sessions`, `resume_policy`), per-packet `write_scope` and
`goal`/verifier, a `pipeline_id`, a `journal` path, and `final_gate` criteria.
Run the full loop in §5.
- **`clarify`** — the goal is ambiguous. Ask `clarify_question` with the candidate
list as ONE batch, then re-run `"$RUNNER" hep-storm "<refined goal>"`. This is
the scope-lock ambiguity gate; do not guess past it.
- **`route`** (single card) — a one-agent storm: borrow and run that card attached
to this project, then still apply the verify → repair → final-gate steps.
- **`hub_fallback` / `hub_candidates`** — Hub lookup used redacted keywords only.
If an `execution` block lists `recommended_agents`, borrow each in stage order
via `"$RUNNER" hep-call "<agent>" "<goal>" --project .` and run them attached to
this repo; otherwise report candidates and offer `/hep-build`.
- **`propose_new`** — no fit exists; offer to build one via `/hep-build`.
- **`refuse`** — explain `reasons` (e.g. loop guard) and stop. Do not retry around
it.
## 5. Run the Stormbreaker Loop over the fabric
Execute the goal to completion under this protocol. **Do not stop to ask for
confirmation** — this is a force-robust run. Only halt when the goal is verified,
or you are genuinely blocked by auth, payment, policy, a missing secret/tool, or
a required user approval.
1. **scope-lock** — Restate the goal as one sentence and lock to it. Check the
route decision's failure-memory. If (and only if) the goal is too ambiguous to
decompose safely, ask ONE batch of 3–5 questions (what NOT to do / smallest
version / done signal / dependencies), then proceed. If it is already specific,
ask nothing.
2. **issue contract** — Write the acceptance criteria: the concrete, checkable
done-signal for each packet and for the whole goal. These become the loop's
stop criteria.
3. **plan-lock** — Adopt the fabric's `parallel_groups` and `depends_on` ordering
as the plan. Open a **visible goal ledger**: packet, owner, verification gate,
status, resume point.
4. **act** — Execute the next unblocked group. Run independent packets in the
group concurrently (delegate with the Task tool where the runtime supports it).
When a packet's `card` names an Agentlas specialist, **borrow and run it
attached to this project** via `"$RUNNER" hep-call "<card>" "<goal>" --project .`
rather than role-playing it. Write artifacts to each packet's `write_scope`.
5. **verify** — A packet passes only when its verifier passes (a packet with a
`loop.goal_command` is met when that command exits 0; an artifact packet is met
when its acceptance check passes). "It ran" is never success.
6. **bounded repair/retry** — On a concrete validation failure, repair and re-run
that packet — bounded. Honor the goal-loop budget: tolerate transient failures
with backoff, stop a packet as `stalled` after consecutive no-progress
iterations, and never exceed its iteration ceiling. A resumed run continues
from the journal, it does not restart.
7. **final-gate** — Report success only if the fabric's final gate clears
(`can_report_success`). Run the evidence/security gate on produced artifacts.
Keep visible progress concise: what was attempted, what was **verified**, and
exactly where to resume if blocked. Never expose hidden reasoning — show
progress, evidence, decisions, and final status only.
## 6. Loop invariants (why this beats a one-shot loop)
- **Don't break (안 끊기게):** a transient packet failure is journaled and retried
with backoff, not fatal. Only a genuine streak of hard failures stops the run.
- **Don't run away:** a hard iteration ceiling plus stall detection — measured
no-progress stops the loop as `stalled` instead of spinning.
- **Keep the goal until done (될 때까지):** the loop reports `reached_goal` only
when the verifier proves it. No bare "it ran" ever counts.
- **Survive a hard stop:** every packet is a journal step, so a killed run resumes
its numbering from the journal instead of colliding or restarting from zero.
## 7. Hard rules
- **No fake pass.** If the engine is unavailable, an account/tool/connector/browser
session is missing, or a gate did not run, report the run as **blocked or
unverified with the exact next step** — never as complete. A scheduled or
materialized run is not proof that an external action succeeded.
- The router only chooses agents and fetches BYOM bundles. Actual tool execution
follows this runtime's own safety and permission model (Claude Code, Codex,
Cursor, etc.).
- Report the `receipt_id`, `pipeline_id`, and `journal` path in your final message
so the run is auditable and resumable.
