Replace the gpt-5.6-only worker path with Implementer/Oracle invocation profiles in the Grok 4.5 CEO core prompt (prompt-only). Keep spawn via bash + senpi --print; doctrine lives in the brief.

Valid — fixed in be5978f.
The 2026-08-01 agent-first subsection is now explicitly the current design. The older “current branch state” notes are labeled Historical notes (superseded by 2026-08-01 agent-first retune) and the obsolete “consult Oracle before deploying” / gpt-5.6-only framing is called out as superseded rather than left as competing present tense.

Mark pre-agent-first Grok notes as superseded so "before deploying" Oracle wording no longer conflicts with the current 2026-08-01 design.

Valid P1 — fixed in 7937eff.
Every Implementer brief doctrine now explicitly includes: do not spawn further workers or nested senpi --print sessions (single orchestration level). Also pinned in prompt-presets-grok-4-5 tests.

Addressed / already superseded in be5978f and re-checked in 7937eff.
There is no remaining present-tense ### What changed (current branch state) block. Historical notes are labeled superseded by the 2026-08-01 agent-first retune, and the current subsection is the source of truth for Oracle wording and model-independent doctrine.
Address cubic P1 by requiring no further senpi --print spawning in every Implementer doctrine handoff, and clarify superseded changelog wording.

P3: This test continues (and substantially extends) a departure from the prompt-preset convention documented in `prompt-preset/AGENTS.md`: prompt-content coverage should assert **parsed rule data** with a placement table (the gpt-5.6 test is the reference shape), not pin free-text sentences. These ~20 new regex/prose pins will fail on any harmless rewording during a future retune, without actually verifying directive placement or that each concern is expressed exactly once.

P2: This narrows the guard from a falsy check to a strict undefined check, which changes behavior for empty-string --system-prompt/append-system-prompt values: "" used to normalize to undefined (no system prompt) and is now passed through as a literal empty prompt. Since the PR is described as prompt-only, this runtime behavior change in resource-loader appears out of scope and untested. If the intent was to keep treating empty strings as absent, keep !input; otherwise add a test covering the "" case.

P3: This test continues (and substantially extends) a departure from the prompt-preset convention documented in prompt-preset/AGENTS.md: prompt-content coverage should assert parsed rule data with a placement table (the gpt-5.6 test is the reference shape), not pin free-text sentences. These ~20 new regex/prose pins will fail on any harmless rewording during a future retune, without actually verifying directive placement or that each concern is expressed exactly once. Consider asserting parsed rule data / section placement instead of raw phrasing, or at least scoping pins to stable signals.

P3: The new 'owning Role section' test only counts directives in the combined CEO section and never checks the owner field, so a rule rendered in the wrong sub-area (e.g. an Implementer directive dropped into the Spawn block) would still pass. Consider asserting the owner-specific rendered line (- **${owner}** — ${directive} for Implementer/Oracle, - ${directive} for Spawn) so the test actually verifies ownership placement, not just exactly-once rendering.

P3: The new empty-string handling in resolvePromptInput changes behavior for append-system-prompt inputs as well as the main system prompt. Because the same helper feeds the append array and only `undefined` is filtered out, an explicitly empty `--append-system-prompt ""` (previously discarded by the old `if (!input) return undefined`) is now retained as an element. Downstream in `_rebuildSystemPrompt` the append array length decides whether to append a `\n\n` separator, so a single empty append now produces a dangling trailing blank line on the base prompt. Consider special-casing the empty-input behavior to the systemPrompt source only (or filtering empty strings out of the append array) so append whitespace/empty inputs behave as before.</violation>

P3: The new defensive `getSystemPromptOptions()` getter protects the `session_start`/`before_agent_start` read paths, but the `model_select` emission still hands event handlers the live `_baseSystemPromptOptions` object via `systemPromptOptions: this.getSystemPromptOptionsFn()` (runner.ts ~1206). Since `model_select` is one of the exact events this PR lists as needing prompt-option provenance, an extension handling it can still mutate live base prompt-construction state (push to `selectedTools`, modify `contextFiles`/`skills`) with no defensiveness. Consider applying the same copy in the `model_select` emission so the protection is consistent across all three target events, or documenting why that path intentionally remains live.</violation>

P3: The --tools read,grep,find,ls assertion is a substring of the longer --tools read,grep,find,ls,bash,edit,write assertion checked just above, so it adds no independent coverage and would not catch the Oracle-only allowlist regressing. Make it distinguish the Oracle allowlist, e.g. by anchoring on the surrounding phrase.

P3: The new empty-string handling in resolvePromptInput changes behavior for append-system-prompt inputs as well as the main system prompt. Because the same helper feeds the append array and only undefined is filtered out, an explicitly empty --append-system-prompt "" (previously discarded by the old if (!input) return undefined) is now retained as an element. Downstream in _rebuildSystemPrompt the append array length decides whether to append a \n\n separator, so a single empty append now produces a dangling trailing blank line on the base prompt. Consider special-casing the empty-input behavior to the systemPrompt source only (or filtering empty strings out of the append array) so append whitespace/empty inputs behave as before.

P3: The new defensive getSystemPromptOptions() getter protects the session_start/before_agent_start read paths, but the model_select emission still hands event handlers the live _baseSystemPromptOptions object via systemPromptOptions: this.getSystemPromptOptionsFn() (runner.ts ~1206). Since model_select is one of the exact events this PR lists as needing prompt-option provenance, an extension handling it can still mutate live base prompt-construction state (push to selectedTools, modify contextFiles/skills) with no defensiveness. Consider applying the same copy in the model_select emission so the protection is consistent across all three target events, or documenting why that path intentionally remains live.

P3: For an explicitly empty `--system-prompt` combined with `--append-system-prompt`, the effective prompt differs by code path. `model_select` (via the new `appendSystemPrompt()` helper) yields the suffix with no leading separator, but `_rebuildSystemPrompt()` in agent-session builds the base prompt as `` "" + "\n\n" + suffix `` (leading `\n\n`). This means the system prompt flickers between the two forms across a model switch versus the next turn. Align the two so an empty base never introduces a leading separator — e.g. build the session base without the separator when `loaderSystemPrompt` is an empty string.</violation>

P3: For an explicitly empty --system-prompt combined with --append-system-prompt, the effective prompt differs by code path. model_select (via the new appendSystemPrompt() helper) yields the suffix with no leading separator, but _rebuildSystemPrompt() in agent-session builds the base prompt as "" + "\n\n" + suffix (leading \n\n). This means the system prompt flickers between the two forms across a model switch versus the next turn. Align the two so an empty base never introduces a leading separator — e.g. build the session base without the separator when loaderSystemPrompt is an empty string.

This MCP registration flake has repeated across multiple empty-commit retries and is outside this PR diff. No merge performed. |
H1: Clone systemPromptOptions in emitBeforeAgentStart to prevent extension mutation of live session state via before_agent_start events. H3: Remove provider credential forwarding from env -i guidance; rely on HOME→auth.json instead of model-authored key literals. H4: Mandate file-based brief transport instead of -p interpolation to close shell injection from repository/user text. M1: Resolve whitespace-only file content to empty string, not undefined, preventing fail-open to full default prompt when role file write fails.

- REG-1: drop the duplicated allowlist phrase from the environment directive. - C-H3: forward credentials by name (`"XAI_API_KEY=$XAI_API_KEY"`) so env-only auth reaches workers and no credential value is ever model-authored. - C-H1: `_emitModelSelect` syncs `_systemPromptOverride`, so a tool continuation or tool-set reconciliation no longer reverts to the previous model's prompt. - C-H2: `BeforeAgentStartEvent.baseSystemPrompt` exposes the pre-chain prompt and `prompt-preset` carries the upstream suffix across its replacement, so a hooks `UserPromptSubmit` `systemMessage` survives preset selection. Registration order is untouched, keeping permission-hook ordering intact. - C-M1: task-management doctrine is injected only when `todo` is in `selectedTools`; an undefined allowlist keeps the previous behavior. - C-L1/M2: `buildSystemPrompt` tests `customPrompt !== undefined`, honoring an explicitly empty replacement instead of rebuilding the default identity. - P3: the header comment names `--system-prompt`, not the user-level brief. - H2: worker isolation documented as session and context isolation, not privilege isolation. - L6: the 8 KiB RETURN schema documented as CEO-parsed guidance, not a control. - M4b: `ExtensionContext.getSystemPromptOptions` is required and the `ExtensionCommandContext` redeclaration is gone; `AgentSession` gains a defensive-copy `systemPromptOptions` accessor for hosts building a context by hand. - L1: clone deep-independence is asserted against a pre-mutation snapshot, so it cannot pass vacuously on empty option fields.

`_emitModelSelect` updated `_systemPromptOverride` after the no-visible-change return, so a `model_select` handler returning `null` could not clear a prior override whose string already equaled the base prompt. A conditional `before_agent_start` modifier records exactly that (it returns `event.systemPrompt` unchanged), so the override outlived the reset and the next `setActiveToolsByName` rebuild read `_systemPromptOverride ?? _baseSystemPrompt` and pinned the pre-reconciliation prompt - a reduced tool set never reached the model. Proven RED first: with tools reduced to `["read", "bash"]` the prompt stayed byte-identical and still described the dropped `write` tool. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Summary
Implementer/Oraclesystem-role profiles.Scope
This started as prompt-only exploration, but review proved that a user-message ROLE brief cannot override a child model preset. The final PR therefore includes the minimal runtime changes in
main.ts,agent-session.ts, resource loading, extension context/runner, and prompt-preset precedence required for the feature to work correctly.Verification
