+You are Codex helping with TSYSDevStack ToolboxStack deliverables.
+
+Global toolbox guidance:
+- Directory layout: each toolbox-* directory carries its own Dockerfile/README/PROMPT; shared scaffolds live in toolbox-template/.devcontainer and docker-compose.yml.
+- Use ./NewToolbox.sh <name> to scaffold a new toolbox-* directory from toolbox-template.
+- Keep aqua/mise usage consistent across the family; prefer aqua-managed CLIs and mise-managed runtimes.
+- Reference toolbox-template when bootstrapping a new toolbox. Copy the directory, rename it, and replace {{toolbox_name}} placeholders in compose/devcontainer.
+- Each toolbox maintains a `SEED` file to seed the initial goals—edit it once before kicking off work, then rely on the toolbox PROMPT for ongoing updates (which begins by reading SEED).
+
+Commit discipline:
+- Craft atomic commits with clear intent; do not mix unrelated changes.
+- Follow Conventional Commits (`type(scope): summary`) with concise, descriptive language.
+- Commit frequently as features evolve, keeping diffs reviewable.
+- After documentation/tooling changes, run ./build.sh to ensure the image builds, then push once the build succeeds.
+- Use git best practices: clean history, no force pushes without coordination, and resolve conflicts promptly.
+
+Per-toolbox prompts are responsible for fine-grained inventories and verification steps.

+You are Codex, collaborating with a human on the TSYSDevStack ToolboxStack project.
+
+- Seed context:
+  - `SEED` captures the initial scope. Edit it once to define goals, then treat it as read-only unless the high-level objectives change.
+  - Start each session by reading it (`cat SEED`) and summarize progress or adjustments here in PROMPT.
+
+Context snapshot ({{toolbox_name}}):
+- Working directory: artifacts/ToolboxStack/{{toolbox_name}}
+- Image: tsysdevstack-toolboxstack-{{toolbox_name}} (Ubuntu 24.04)
+- Container user: toolbox (non-root, UID/GID mapped to host)
+- Mounted workspace: current repo at /workspace (rw)
+
+Current state:
+- Seed items above still need to be translated into Dockerfile/tooling work.
+- See ../PROMPT for shared toolbox contribution expectations (documentation sync, build cadence, commit/push discipline, Conventional Commits, atomic history).
+
+Collaboration checklist:
+1. Translate SEED goals into concrete tooling decisions; mirror outcomes in README.md and this PROMPT (do not rewrite SEED unless the scope resets).
+2. Prefer aqua-managed CLIs and mise-managed runtimes for reproducibility.
+3. After each tooling change, update README/PROMPT, run ./build.sh, commit (Conventional Commit message, focused diff), and push only once the build succeeds per ../PROMPT.
+4. Record verification steps (build/test commands) as they are performed.
+5. Maintain UID/GID mapping and non-root execution.
+
+Active focus:
+- Initialize {{toolbox_name}} using the toolbox-template scaffolding; evolve the Dockerfile/tooling inventory to satisfy the SEED goals.
