Praxist Onboarding

Praxist Onboarding

Use this skill to give the current agent enough Praxist system context to be useful on a first interaction. Keep the explanation system-level: describe purpose, operating model, configuration surfaces, software boundaries, and key module locations. Do not paste large code blocks or task-specific benchmark logic into the conversation.

Onboarding-Only Invocation

This skill is primarily for context establishment. If the user invokes only:

praxist-onboarding

or otherwise asks only to understand Praxist, do not start a run, initialize a task, edit files, change configuration, install dependencies, or perform any state-changing environment operation. Load the Praxist context, run the default read-only environment scan below, give a concise readiness note, and wait for the user's next instruction.

Use this shape for a bare invocation:

Praxist onboarding context loaded. I understand the system as a task-agnostic autonomous-research control plane with task projects, peers, generations, frontier/incubator/Gems, PI/Chair planning, plugin boundaries, and packaged docs/templates/skills. I will run a read-only environment scan, report the result, and then wait for your next instruction.

The read-only environment scan below is part of the default onboarding action. Only take write or runtime action when the user gives an explicit goal such as installing a skill, changing configuration, creating a task project, running praxist resolve, launching a run, inspecting a run deeply, or editing code.

Default Read-Only Environment Scan

When this skill is invoked, perform this read-only scan by default unless the user explicitly says not to scan. Do not install packages, modify shell config, start runs, write env files, edit task files, or change credentials during this scan.

Keep discovery bounded. If using ls, find, fd, rg --files, or similar filesystem discovery commands, limit the scan to explicitly selected roots and no more than two directory levels below each selected root. For default onboarding, the selected roots are the current directory and its immediate parent-level candidates only. Never recurse through /, $HOME, mount roots, shared-storage roots, full workspace roots, datasets, caches, or experiments/ trees during this scan.

Check these surfaces:

1. Praxist command and pip package

   • command -v praxist
   • praxist --help when praxist exists
   • python -m pip show praxist when Python/pip are available
   • python -c "import praxist; print(praxist.__file__)" to locate the imported package

2. Source checkouts near the current directory

   • Inspect the current directory and one parent level for Praxist source trees.
   • A source tree is likely present when pyproject.toml declares name = "praxist" and a praxist/ package directory exists.
   • If a source tree is git-managed, report branch and cleanliness with git status --short --branch.

3. Agent skill installation

   • Detect expected Praxist skills from the source checkout when present: skills/*/SKILL.md.
   • Otherwise check the current bundled set: praxist-onboarding, praxist-runtime-install, praxist-task-initialization, praxist-scientific-research, praxist-interactive-task-init, praxist-takeover, praxist-takeover-codex, praxist-control, praxist-diagnostic, and terminal-line-plot.
   • Check the current host's skill root for each expected skill: ${CODEX_SKILLS_DIR:-~/.agents/skills} for Codex or ${CLAUDE_SKILLS_DIR:-~/.claude/skills} for Claude Code.
   • If a skill is a symlink, report the symlink target.
   • If a skill is a copied directory, report that updates may require reinstalling or copying again.

4. Environment variables and keys

   • Report provider keys by presence only: DEEPSEEK_API_KEY, OPENROUTER_API_KEY, ORCAROUTER_API_KEY, ANTHROPIC_API_KEY, OPENAI_API_KEY, MOONSHOT_API_KEY, DASHSCOPE_API_KEY, GOOGLE_API_KEY, MISTRAL_API_KEY, GROQ_API_KEY, XAI_API_KEY.
   • Report non-secret Praxist configuration values when relevant: PRAXIST_AGENT_SYSTEM, PRAXIST_LLM_PROVIDER, PRAXIST_STATE_DIR, PRAXIST_TASK_PROJECT_PATH, PRAXIST_MODEL, PRAXIST_MODEL_PROVIDER_REF.
   • Never print raw values for variables containing KEY, TOKEN, SECRET, PASSWORD, or CREDENTIAL.
   • Only when Codex-native mode is explicitly selected, report saved-auth readiness as ChatGPT login present or not present using praxist doctor --codex-native. For every other profile report not checked and do not probe subscription authentication. Never read auth files or display account identifiers/tokens.

Use a concise result table with: detected source checkout(s), pip package status, praxist CLI status, skill install status, configured provider keys, selected Praxist agent/provider env, and recommended next action. Prefer DeepSeek direct when available: DEEPSEEK_API_KEY + model_provider:deepseek_alias + deepseek-v4-pro.

Source Order

Prefer live repository or installed-package facts over memory.

1. If a Praxist source checkout is available, read the smallest relevant subset of:

   • README.md
   • docs/index.md
   • docs/getting-started/quickstart.md for first-use mode selection
   • docs/concepts/architecture.md
   • docs/concepts/runtime-model.md
   • docs/concepts/config_discipline.md
   • docs/guides/task-projects.md
   • docs/guides/operators.md
   • docs/guides/research-loop-variant-generation-flow.md
   • docs/guides/model-providers.md, docs/guides/credentials.md, docs/guides/budget-policies.md when provider, key, or cost behavior matters
   • docs/reference/cli.md or docs/reference/skills.md only when an exact command or Skill activation contract is needed

2. If only the pip package is installed, inspect the installed CLI, package metadata, and packaged resources:

   • praxist --help
   • praxist <subcommand> --help for the specific command
   • python -c "import praxist, inspect; print(praxist.__file__)"
   • package metadata such as python -m pip show praxist
   • packaged docs under praxist/resources/docs/
   • packaged complete examples under praxist/resources/examples/
   • packaged task templates under praxist/resources/templates/
   • packaged skills under praxist/resources/skills/

3. To locate packaged resources from an installed wheel, run:

   python - <<'PY'
   from importlib.resources import files
   root = files("praxist")
   print(root / "resources" / "docs" / "index.md")
   print(root / "resources" / "examples")
   print(root / "resources" / "templates")
   print(root / "resources" / "skills")
   PY
   

4. Treat command suffixes under praxist * as evolving. Always verify with praxist --help before giving exact syntax unless the user supplied the command contract in the current thread.

5. Never infer task-specific behavior from any individual task project as generic Praxist behavior. Praxist must remain task-agnostic.

Mental Model

Praxist is a generic autonomous-research control plane. It runs a simulated research lab over an external task project.

• A task project defines the actual research problem, baselines, datasets, evaluation protocol, task-local roles, and output policy.
• A peer is one autonomous agent session with tools. It reads the task context, writes candidate variants, runs evaluations, and emits structured evidence.
• A cohort is a group of peers running in parallel inside one generation.
• A generation is one research round. After enough evidence accumulates, the system closes the generation, ingests results, updates memory/frontier state, and plans the next round.
• A task that distinguishes mature/complete evidence from preliminary or diagnostic evidence should use a positive mature close quorum. Raw finding density may begin assessment, but it should not become normal completion; scheduler mature-supply targets prioritize work and do not create this gate.
• A task may enable the central experiment scheduler. Peers then submit stable semantic experiment IDs plus task-declared resource profiles and work classes; Praxist alone performs admission, final process launch, any backend-supported device assignment, infrastructure retry, and release. CPU pressure changes total experiment concurrency rather than reserving cores per job. Generation close freezes new/queued work while active process groups drain.
• Findings are structured evidence records. They explain what a result means, not just what files were produced.
• Result artifacts are machine-readable outputs under recursive results/**/ paths. Compact summaries use supported names such as summary.json, evaluation_summary.json, eval_summary.json, tiered_eval_summary.json, or custom_*_tiered_eval_summary.json; the compatibility name result_summary.json is also accepted. They carry structured lane, maturity, ratio, protocol, and diagnostic metadata for materialization.
• Frontier contains durable high-value candidates selected for continued attention.
• Incubator keeps lower-admission but still durable, task-authorized, protocol-passed, non-suspect Pareto/new-high candidates so they are not discarded too early. Modes that the task marks non-parentable and protocol-suspect signals belong in validation candidates until the declared protocol authorizes them.
• Gems are compact long-horizon memory anchors, usually refreshed on reset cycles, that preserve especially valuable candidates or mechanisms.
• PI/Chair panels synthesize prior evidence into per-peer contracts for later generations.

The task owns maturity meaning, subject to the user's explicit protocol intent. When a task enables require_ratio_gate: true, its evaluator emits finite effort_ratio and coverage_ratio values. Staged protocols may additionally declare task-owned complete_stage_labels / preliminary_stage_labels; despite the compatibility field name, complete_stage_labels means the labels the task declares mature and may include an explicitly authorized reduced mode. Labels are optional vocabulary and never replace ratio evidence when the gate is enabled. With a required gate, missing ratios remain unknown. Only mature durable lanes set parent_eligible: true; lower-tier and diagnostic lanes set it false even when they retain useful signals for revalidation. New Gems configuration uses selection_policy: mature_evidence_top_k and a task-owned min_mature_eval_units derived from the protocol authorized for Gems and durable parent use. Staged tasks use evidence_stage_min_units to map their own labels to cumulative evaluation-unit requirements.

Praxist does not centrally generate research code. Peers generate variant code by reading task instructions, baselines, agendas, and evidence, then editing task/run-local files through their agent runtime.

Optional scientific research support includes no-key tool_server:literature_lookup for literature/database/open-access context and a disabled-by-default local reviewer stage for artifact/provenance consistency checks. These are context/audit helpers, not replacement evaluators and not promotion mechanisms. Literature lookup is current-environment-only: sources can inform better solutions under the task's existing local data, dependencies, evaluator, hardware, and runtime, but must not cause agents to download new datasets, install dependencies, provision simulators, or create new runtime environments during a run.

Run artifacts are layered by ownership:

• Canonical current state: measured result/finding evidence, frontier/frontier_manifest.json, committed gems/gems_state.json, and gen_N/generation_boundary.json. The contiguous boundary markers, not optimistic status or frontier presence, define how many generations are committed. Markerless results/frontier state form a recoverable pending boundary. A predecessor run created before the marker contract may have a committed frontier-and-agenda prefix; resume may infer and atomically backfill that prefix once before applying the marker contract to all later generations.
• Validation signals: compact non-frontier leads such as task-defined preliminary, aligned, partial, failed-but-informative, lower-stage, or late-after-boundary result evidence. Late-after-boundary means a result summary was written after its generation boundary evidence cutoff; Praxist preserves it in the normal finding store for PI and later follow-up but does not treat it as clean promotion truth until revalidated. For expensive tasks, preliminary evidence is triage only; only a task-declared aligned stage should rank variants before complete evaluation, and that stage should keep the same or near-complete data/evaluation coverage while reducing training or optimization effort first. Praxist reads maturity from task-defined effort/coverage ratios and explicit stage-label mappings, not from globally meaningful tier names.
• Derived views: leaderboards and compact status/diagnostic tables generated from canonical state.
• Audit snapshots: rendered prompts, prompt layouts, PI evidence packs, PI agendas/memos, reviewer reports, logs, and behavior reports that preserve what agents saw or what an audit checked.
• Partial outputs: temporary, rejected, candidate, or interrupted phase files that resume/control should ignore or crop before continuation.

This distinction is central to current Praxist behavior. Derived/audit artifacts remain visible for replay and analysis, but runtime readers should not treat old snapshots as current truth.

Current template-style task descriptors run DIG only for absolute generation 0 by default: dig_lite.enabled: true with dig_lite.generation_scope: initial_only. QD is independent: quality_diversity.initial_generation_enabled controls QD over the gen0 DIG pool, while quality_diversity.later_generations_enabled controls QD over the existing PI synthesis path in later generations. Multi-PI uses the union of PI memo proposals plus Chair allocation; single-PI performs the same soft guidance inside its normal synthesis call. Periodic Gems reset stays off by default through gems.enabled: false. Operators may independently disable either QD phase, disable constructive peer-mix feedback, restore legacy all-generation DIG explicitly, or enable Gems reset after task evidence justifies the choice.

What Praxist Owns

Praxist owns the generic control plane:

• CLI lifecycle and run registry.
• Task-project loading and validation.
• Plugin discovery and resolution.
• Prompt layout rendering and replay manifests.
• Agent runtime normalization.
• Model provider and credential references.
• Budget ledgers and cost policy hooks.
• Cohort and generation orchestration.
• Shared finding ingestion and finding graph maintenance.
• Frontier, incubator, Gems, and research memory maintenance.
• PI/Chair synthesis and next-generation agenda generation.
• Replay, artifact indexing, redaction, and run inspection.

Praxist does not own the user's actual research domain. Real research task logic belongs in an external task project, not in praxist/core or bundled generic plugins.

Software Architecture

Use this architecture split when answering design or debugging questions:

praxist.core
  Stable contracts: run config, protocol dataclasses, storage, replay,
  credentials, budget ledgers, task project resolution, plugin registry,
  prompt layout, runtime/provider interfaces.

praxist.plugins
  Generic replaceable components: agent runtimes, model providers,
  workflow stages, tool servers, graph maintainers, budget policies,
  panel topologies, roles, audit rules, evaluations.

external task project
  The actual research problem: task.yaml, description, roles, evaluations,
  harness, baseline, fixtures, datasets metadata, audit rules, experiments/.

Important current module areas:

• CLI entrypoint: praxist/cli/__init__.py
• Start/stop/status/init/resolve commands: praxist/cli/*.py
• Direct module runner: praxist/run.py
• Frozen run configuration: praxist/core/run_config.py
• Task project contract: praxist/core/task_project.py
• Plugin registry: praxist/core/registry.py
• Runtime contracts: praxist/core/runtimes.py
• Workflow contracts: praxist/core/workflow.py
• Research loop plugin: praxist/plugins/workflow_stages/research_loop/
• Model providers: praxist/plugins/model_providers/
• Agent runtimes: praxist/plugins/agent_runtimes/
• Tool plugins: praxist/plugins/tools/

Treat praxist as the only implementation package and installed console script. Do not infer parallel package or CLI identities.

Installation And CLI Context

Praxist is distributed as the praxist Python package and exposes:

praxist = praxist.cli:main

For source checkouts, the common developer path is:

uv sync
uv run praxist --help

For installed environments, assume the user expects:

praxist --help

For first use in an operator-selected Python environment, install the complete runtime extras before entering the existing setup state machine:

python3 -m pip install --index-url https://pypi.org/simple "praxist[agents,codex]"
praxist setup --agent-managed  # agent-managed lane

Installed wheels include the full Praxist documentation, complete examples, task templates, and skill source tree as package resources:

praxist/resources/docs/
praxist/resources/examples/
praxist/resources/templates/
praxist/resources/skills/

Use those packaged resources when no source checkout is available. Do not assume the user has a repository clone after pip installation. Package resources are read-only distribution sources: praxist setup materializes every bundled example, while praxist examples install <name> materializes one selected example under ${PRAXIST_EXAMPLES_HOME:-~/PraxistExamples}. Never launch or write run output inside a source/package-resource copy. Packaged templates remain the right place to inspect official task-project shape before scaffolding a new task.

Current operational CLI verbs include start, stop, status, resume, and resolve; setup and support verbs include doctor, docs, setup, configure-llm, install-skills / uninstall-skills, examples, and the first-project takeover handoff. uninstall removes only a verified current-user Praxist installation and refuses to run while local research is active; it never removes task projects or run directories. For a first-time agent-managed installation, follow docs/agents/oobe-install.md before ordinary onboarding. Verify current help before relying on a command.

Treat successful pip installation as the package boundary, not OOBE completion. Continue explicit User-Agreement acceptance, profile selection, safe skill registration, and readiness. Never accept the Agreement on the operator's behalf. Never pass --force-unmanaged without showing the operator every same-name conflict and receiving an explicit backup-and-replace choice. Immediately query praxist setup --agent-managed, follow its next_required_action, and rerun it after each decision. Do not infer profile selection from a saved login, environment key, provider default, or doctor success. Once setup_decisions_complete is true, run readiness checks and stop. Installation must not select a project or invoke takeover; those require a separate request after the operator reads docs/getting-started/first-task.md.

Operator intent usually maps like this:

• "What is this / how do I start?" -> explain Praxist and run praxist --help.
• "Open the documentation" -> run praxist docs; on SSH or a headless host, present the printed authenticated Pages URL rather than starting a local server.
• "Create a new task" -> invoke praxist-task-initialization, use praxist-interactive-task-init when confirmation is required, or inspect task templates.
• "Show a complete example" -> run praxist examples list, use the printed writable project path, and distinguish it from replaceable task templates.
• "Check task wiring" -> use praxist resolve.
• "Launch a run" -> use praxist start; praxist start / praxist resume do not open a monitor. Their result and any agent handoff must clearly report praxist --monitor --run-id <run_id>.
• "Monitor runs" -> use praxist status, inspect the run directory, or open the independent foreground TUI with praxist --monitor, praxist --monitor --run-id <run_id>, or praxist --monitor --latest. Use praxist --monitor --plain only for non-interactive or append-friendly text output. Ctrl-C exits only the monitor interface and leaves the Praxist run active.
• "Stop runs" -> prefer praxist stop <run-id>; it manages only the run. Use praxist stop --all only when the user explicitly asks to stop every registered Praxist run in the environment; do not use it as the default stop path for a single research task.
• "Interactive guidance" -> use the installed Praxist skills for the current agent host when available.

Task Templates And Complete Examples

The templates/ tree is the canonical scaffold surface for task authoring. It is especially important for later skills that convert a user's own research directory into a formal Praxist task project. The separate examples/ tree contains complete task-specific reference projects and must not be treated as a generic scaffold.

Locate it in one of two places:

source checkout:  templates/
pip wheel:        praxist/resources/templates/

Use the task templates this way:

• templates/tasks/template/ is the primary scaffold for a new task project. Future task-conversion skills should use its structure as the target shape.
• templates/tasks/toy_math/ is the offline smoke fixture. Use it to understand the minimal no-network task contract and resolve-only behavior.
• templates/tasks/sam_optimizer/ is a realistic ML-style task reference. Use it to understand a richer task layout, but do not copy SAM-specific research logic into generic Praxist docs, prompts, or plugins.

Use examples/rocket_booster_recovery/ and examples/rocket_booster_recovery_rust/ only to inspect complete Python/JAX and Rust integrations of project code, frozen assets, evaluator, task harness, and evidence. Operate an installed writable copy reported by praxist examples list; never infer cross-task defaults from either example's control-domain metrics or hardware profile.

For task-conversion work, read these files first:

templates/README.md
templates/tasks/README.md
templates/tasks/template/README.md
templates/tasks/template/task.yaml
templates/tasks/template/description.md
templates/tasks/template/prompt_task.jinja2

Then shape the user's research directory into the same task-project contract:

• task.yaml for identity, metrics, workflow refs, model/runtime defaults, task entrypoints, runtime environment, output roots, task-local refs, and assets.
• description.md for the agent-facing research brief, scope constraints, success criteria, and evaluation rules.
• README.md for operator-facing setup and run instructions.
• roles/ for task-specific peer, PI, Chair, reviewer, or specialist contracts.
• audit_rules/ for declarative task-specific scope, claim, and agenda criteria.
• evaluations/ for the public evaluator command and metric interpretation.
• assets/ for harness code, baselines, dataset metadata, literature, fixtures, and optional reference implementations.
• .gitignore to exclude experiments/, raw datasets, logs, caches, local secrets, and bulky generated artifacts.

Do not teach users to edit praxist/plugins/** to create a research task. A user task belongs in the user's task directory; Praxist generic code should remain task-agnostic.

User-Level Run Flow

Before explaining peers or generation internals, orient new users around the external workflow:

pip install / source checkout
  -> user opens a task project directory
  -> Praxist reads task.yaml and task-local assets
  -> user verifies wiring and credentials
  -> user starts a run
  -> Praxist writes an experiments/run_* directory
  -> user monitors, stops, resumes, or inspects that run

A task project is the user's research problem directory. It usually contains task.yaml, description.md, task-local roles, evaluations, assets, baselines, and an ignored experiments/ output directory. Praxist is the runner and research control plane; the task directory supplies the problem and evaluation contract.

When helping a first-time user, prefer this order:

1. Ask for or locate the task project directory.

2. Run or suggest praxist --help to verify the installed command surface.

3. Inspect task.yaml and the task README/description before giving run-specific advice.

4. Use praxist resolve when available to check plugin refs, task-local refs, and required assets.

5. Confirm required model-provider credentials by presence only, never by printing values.

6. Start from the task directory or pass --task-path explicitly:

   praxist start --task-path /path/to/task-project
   

7. Monitor with praxist status, inspect the run directory under the task project's experiments/, or run praxist --monitor --run-id <run-id> in a separate foreground terminal. Ctrl-C exits the TUI without affecting the Praxist run.

8. Stop registered runs with praxist stop <run-id>; this manages only the run. Use praxist stop --all only when the user explicitly asks to stop every registered Praxist run in the environment.

Research Loop Behavior

The default v1 workflow stage is workflow_stage:research_loop.

Typical flow:

task project
  -> startup resolves task.yaml, plugins, credentials, runtime env
  -> prompt layout is rendered per peer
  -> cohort peers run through agent runtimes
  -> peers create variants and results under the run directory
  -> peers publish findings and artifacts
  -> generation boundary ingests and materializes evidence
  -> finding graph, frontier, incubator, Gems, and memory update
  -> PI/Chair panel writes next-generation agenda
  -> next generation starts with per-peer contracts

Gen 0 usually emphasizes broad exploration from the task prompt and baseline. Later generations receive PI/Chair agenda contracts, frontier/incubator/Gems summaries, negative evidence, and research memory. Explicit strategies such as explore, mixed, or exploit may exist for debugging or operator override, but auto is the normal PI-directed path.

The LLM/session boundary is event-driven. A peer session returns, then waits for meaningful events such as new findings, stop signals, workflow completion, or heartbeat expiry. This avoids idle token spend while preserving long-run survivability.

For Codex-native mode and OpenRouter routes, explain that Praxist automatically coalesces finding-only event bursts before opening another peer session. Stop, closing, and resource-supply events remain immediate; the full task prompt, canonical findings, and archived tool outputs remain available. This is lossless navigation and session-count control, not context compression. Direct DeepSeek is explicitly excluded and keeps its established event cadence and prompt behavior. Point users to docs/guides/cost-optimization.md for PRAXIST_CONTEXT_EFFICIENCY_MODE, interval tuning, and usage interpretation.

Configuration Rules

Use this priority model:

CLI args > explicit env vars > override spec > task.yaml defaults

Credentials are special: raw secrets should be resolved through credential/provider logic and never copied into task.yaml, logs, docs, or prompts.

Key configuration principles:

• PRAXIST_* is the canonical Praxist env prefix. Some legacy bare env names may still be accepted as fallback.
• Core and plugin domain code should not read os.environ directly.
• Env reads belong at CLI entry boundaries and subprocess env construction boundaries.
• Downstream code should consume frozen RunConfig values or domain dataclasses derived from it.
• When exact usage is missing, Praxist records usage_unknown; do not silently convert unknown cost to zero.
• Do not print raw API keys. Report whether required credential variables are present, not their values.

Common provider/key context:

• Anthropic native: ANTHROPIC_API_KEY
• OpenRouter: OPENROUTER_API_KEY
• OrcaRouter: ORCAROUTER_API_KEY
• Cloudflare Workers AI: CLOUDFLARE_API_KEY plus CLOUDFLARE_ACCOUNT_ID
• DeepSeek direct: DEEPSEEK_API_KEY
• OpenAI-compatible: OPENAI_API_KEY
• Groq: GROQ_API_KEY
• Mistral: MISTRAL_API_KEY
• xAI: XAI_API_KEY
• Agent system selector: PRAXIST_AGENT_SYSTEM or --agent-system
• Provider selector: PRAXIST_LLM_PROVIDER or --model-provider
• Config profile: command-local --config-file, then PRAXIST_CONFIG_FILE, then the user default
• Task path: --task-path, then TASK_PATH, then invocation directory
• State registry root: PRAXIST_STATE_DIR

Keep direct agent skill use distinct from peer execution:

• The Codex or Claude Code CLI in which this skill runs is a human operator interface that invokes bundled Praxist skills directly.
• agent_runtime:codex_sdk is an optional peer runtime implemented with the tested official openai-codex==0.147.0 Python SDK and long-lived local app-server clients. It connects selected MCP servers directly and consumes typed notifications; it does not replay a human Codex CLI session. For native OpenAI only, it may use the saved ChatGPT authentication owned by the SDK-bundled Codex binary.

The default peer runtime remains agent_runtime:claude_sdk. If the user explicitly selects agent_runtime:codex_sdk, verify the Praxist environment has openai-codex==0.147.0, claude-agent-sdk==0.2.136, codex-relay==0.5.5, and MCP support. For the default Claude runtime, verify claude-agent-sdk==0.2.136. OpenAI connects directly. DeepSeek and OpenRouter use a private run-scoped relay because those providers expose Chat Completions while Codex expects Responses. Praxist owns that relay; task projects and users should not launch one per peer.

When reasoning behavior matters, inspect task.yaml:agent.reasoning_effort. auto preserves the selected provider/runtime behavior; explicit off/low/high/max applies run-wide to peers, DIG, PIs, and Chair. Explain that Praxist performs the runtime-specific mapping and that changing effort can change latency, output usage, and cost. Do not copy provider wire fields into a task project.

For Codex-native mode with native OpenAI, run praxist setup --profile codex-native --install-skills codex in a local terminal, then select --codex-native for lifecycle commands. Setup verifies or repairs only the SDK-pinned Codex login. Do not require this subscription check for another profile. The explicit mode fixes agent_runtime:codex_sdk plus model_provider:openai_compatible and removes API-key/custom-endpoint and inherited provider/model defaults after configuration loading. Outside that mode, configured credentials retain normal precedence. Never claim Codex-native authentication works with a relay provider.

Current preferred low-cost research configuration is DeepSeek direct API:

export DEEPSEEK_API_KEY="..."
praxist start \
  --task-path /path/to/task-project \
  --model-provider model_provider:deepseek_alias \
  --runtime agent_runtime:claude_sdk \
  --model deepseek-v4-pro

For agent-system short-name paths, the same provider can be selected explicitly:

export DEEPSEEK_API_KEY="..."
export PRAXIST_AGENT_SYSTEM=claude_sdk
export PRAXIST_LLM_PROVIDER=deepseek
praxist start --task-path /path/to/task-project --model deepseek-v4-pro

model_provider:deepseek_alias is an OpenAI-compatible DeepSeek provider. Its current default model is deepseek-v4-pro; cheap_peer maps to deepseek-v4-flash, and strong_reasoner maps to deepseek-v4-pro.

Emphasize the cost model: Praxist prompt layout keeps large frozen and semi-static prompt blocks stable across peers and generations, and the DeepSeek long-context route can achieve cache hit rates above 95% in well-structured long runs. Because cached tokens are much cheaper than uncached tokens, this is currently the most cost-effective configuration for large Praxist research runs when the task does not require a different provider.

Do not promise a 95%+ cache hit rate for tiny smoke tests, heavily changing prompts, or misconfigured runs. Present it as the expected advantage of the recommended DeepSeek setup when prompt layout stability is preserved.

For Codex-native mode/OpenRouter diagnostics, do not treat cache hit rate as the only cost measure. Also inspect fresh session count, sessions per peer-generation, total input, cached input, and uncached input. A high cache hit rate can still accompany excessive logical input when agents repeatedly rebuild the same context through shell reads.

Task projects can declare a runtime_environment block in task.yaml. Praxist validates and injects task-local runtime values such as PRAXIST_TASK_PYTHON, PRAXIST_TASK_VENV, VIRTUAL_ENV, PRAXIST_TASK_SHELL_PREFIX, and PATH additions so peer commands run in the task's environment.

Task projects should also declare generation-scoped DIG, independent QD, constructive peer-mix, and Gems policy in task.yaml when they are intended for real research. Use templates/tasks/template/task.yaml for the generic shape and richer reference templates such as templates/tasks/sam_optimizer for a task-local staged protocol. Keep labels and thresholds task-owned; one task's stage names or evaluation-unit counts are not generic Praxist defaults.

Task Project Boundary

A real task project normally contains:

• task.yaml
• description.md
• task-local roles/
• task-local audit_rules/
• task-local evaluations/
• assets/ for harness code, baselines, fixtures, dataset metadata, and references
• ignored experiments/ for run outputs

Task-local refs such as task_role:*, task_audit:*, and task_evaluation:* resolve inside the selected task project. Bundled generic refs such as workflow_stage:*, model_provider:*, and agent_runtime:* resolve through Praxist plugins.

Never add a private task's role prompts, benchmark logic, datasets, or domain-specific guardrails into Praxist core or bundled generic plugins. If two unrelated task projects cannot reuse a component, it probably belongs in the task project.

Run Artifacts

Long-running run directories are a product surface. Important artifacts often include:

run.json

Compatibility or task-specific runs may also materialize shared_store.db, shared_findings/, STOP_SIGNAL, graph artifacts, variants/, results/, and agendas/.

When debugging a candidate that "did not affect the next generation", check:

1. Variant code exists under variants/<variant_name>/.
2. Evaluation artifacts exist under results/<variant_name>/.
3. A canonical finding exists or the result artifact was materialized.
4. Frontier/incubator/Gems state references it when appropriate.
5. The next agenda references it if PI/Chair decided to use it.

Safe Operating Rules

• Prefer praxist stop over process-list killing when a run is registered.
• Do not write production run artifacts into the Praxist source checkout.
• Do not mutate a task project while answering conceptual questions unless the user requested edits.
• Do not push to remote repositories unless explicitly requested.
• Do not expose secrets. Redact keys and credential-bearing env.
• Do not over-tighten guards or filters unless the user asks for enforcement. Praxist favors "capture first, label uncertainty, continue when safe."
• Preserve weak but useful evidence with clear provenance labels instead of deleting it.
• Use current CLI help and docs for exact command names because the praxist * surface is evolving.

Response Pattern For New Users

When a user opens Codex or Claude Code after installing Praxist, respond in this order:

1. If the user only invoked the skill or only asked to understand Praxist, establish context, run the default read-only environment scan, report the concise result table, and wait.
2. Identify whether they are in a source checkout, an installed pip environment, or a task project from the scan result.
3. Verify the CLI surface with praxist --help when commands matter.
4. Explain Praxist as a generic autonomous-research control plane, not the research task itself.
5. Ask for or locate the task project path before giving run-specific commands.
6. For setup, check provider credentials by presence only.
7. For task creation, invoke the task-initialization skills directly. For run operations, prefer praxist resolve, praxist start, praxist status, praxist stop, and praxist resume when available.
8. For architecture or development work, read the architecture docs and keep generic Praxist logic separate from task-specific logic.

Keep answers practical. Give the smallest next command or file path that moves the user's setup forward, and only expand into architecture details when they are needed for the user's decision.
