Fritz Infrastructure Operating Framework is the infrastructure operations module of the FRITZ ecosystem: a vendor-neutral, open-source engineering framework for engineers and The Agent.
Infrastructure should remember. Operational knowledge belongs with the resources it describes so engineers, organisations and AI models can change without losing continuity. FIOF combines a safety contract, persistent records, reusable procedures and optional platform modules. It works independently of FRITZ services.
Status: 0.1.0 experimental foundation. Platform modules are guidance, not certified integrations. There is no autonomous executor. Access controls and approval enforcement remain with the operator and execution environment.
No programming runtime is required to use FIOF. An engineer or The Agent can read the documents and maintain the knowledge files directly. Node.js is only needed if you choose to run the optional initializer or repository checks.
For security findings, tested protections and open release gates, read the security review and deployment controls. No claim of 100% security or certified autonomous operation is made.

FIOF gives engineers and The Agent a repeatable way to operate infrastructure and leave durable records for whoever works on it next. The repository supplies the operating rules, procedures and templates; each resource's separate knowledge base stores its identity, verified state, evidence, changes and handover.
For example, when investigating a failing service, The Agent reads previous findings, verifies the current resource and collects fresh evidence. Before an authorized repair it records a plan and recovery path, then verifies the outcome and saves what happened. A different engineer or agent can later read those files and continue without the earlier conversation.
The optional initializer only creates the knowledge directory and starter records. FIOF does not launch an agent, connect to infrastructure, monitor services or execute repairs automatically. You supply the agent's tools and permissions; FIOF defines the process it should follow and the records it should leave.
| Component | What it provides | Who uses it |
|---|---|---|
| Core contract | Identity, authority, evidence, backup and validation requirements | Engineers and The Agent |
| Procedures | Workflows for discovery, repair, maintenance, recovery and migration | Whoever performs the task |
| Modules | Additional guidance for relevant domains and detected products | Whoever needs that platform context |
| Templates and schemas | Consistent operational records and metadata | The writer of the resource knowledge base |
| Resource knowledge base | Actual facts, evidence, decisions, open work and handover | Current and future operators |
| Optional tools | New-directory scaffolding and repository checks | Operators and contributors who choose to run them |
FIOF's purpose is operational continuity. It complements the tools you already use to manage infrastructure; it supplies neither a replacement control panel nor a background service. The acronym stands for Fritz Infrastructure Operating Framework. FRITZ is the parent ecosystem, but no FRITZ account or service is needed.
For the framework itself, you need a readable copy of this repository, a protected durable place for resource records, and an engineer or agent able to read and write those files. Actual infrastructure work additionally needs authorized access to the specific resource and suitable operational tools.
| Requirement | Necessary? | Purpose |
|---|---|---|
| Framework documents | Yes | Defines the process to follow |
| Resource knowledge storage | Yes | Preserves continuity beyond a conversation |
| AI agent | No | Engineers can follow exactly the same framework manually |
| Git | Optional | Convenient way to obtain and track framework releases; an extracted archive also works |
| Node.js 22 or later | Optional | Runs the bundled initializer and repository checks |
| Package installation | No for bundled tools | The helpers have no third-party dependencies |
| Administrator/root access | Not inherently | Only specific authorized operations may need elevation |
| Internet access | Not inherently | Local framework use works offline; obtaining files and your chosen agent/tools may need connectivity |
The Agent's own requirements remain separate. For example, an externally hosted agent may need a network connection even though FIOF's records are local files.
FIOF is usable now for supervised adoption. It is not certified as fully production-ready, and version 0.1.0 remains experimental. Deploying FIOF means making reviewed framework documents and protected resource records available to an engineer or The Agent; it does not install an autonomous infrastructure service.
| Intended use | Current position |
|---|---|
| Learn the framework or maintain records manually | Available now; use the contracts and templates |
| Supervised discovery and documentation | Start with a bounded pilot and enforce read-only infrastructure access |
| Use alongside existing production operating procedures | Adopt with owner review, approved data handling and protected records; preserve existing change controls |
| Agent-executed infrastructure changes | Require environment-specific permission, backup, restore and validation evidence before each authorized scope |
| Unattended production operation | Not demonstrated or certified by this project |
Start on a non-production resource. Verify a fresh-session handover and an isolated knowledge restore, then test a small reversible change under explicit authority. Before expanding to production, demonstrate the deployment controls and conformance scenarios for your tools and environment. An agent's ability to access a server is not evidence that it will operate it safely.
The helper suite passed on Windows and on Linux containers using runtime versions 22 and 24. This supports confidence in the tested scaffolding behaviour, not in every infrastructure operation. macOS execution, hosted CI, independent review and live operational pilots remain outstanding in the current security review. A future version number alone will not replace that evidence.
- Read the architecture review.
- Follow onboarding to choose protected durable storage and verify resource identity and authority.
- Apply the core, knowledge and relevant modules.
- Discover, plan, back up, execute within authority, verify and persist a handover.
The resource model covers Linux, Windows, containers, virtualisation, cloud, hosting, networking and databases. New domains and products extend the module contract. Knowledge uses UTF-8 files and JSON metadata without a required runtime.
Download and extract a reviewed repository archive, or use Git:
git clone https://github.com/zacdreyer/FIOF.git
cd FIOFIf you already have a checkout, open its root directory. No Node.js installation
is required for the manual or agent-led steps below. Record the framework version
from VERSION; see release guidance when selecting an update.
First read the core and knowledge contract.
Verify the resource identity and your authority, then choose a stable resource ID.
The examples below use example-01; replace it with your resource's ID.
Choose a new directory outside the framework checkout, under an existing protected parent. These examples use your home directory; verify its permissions or Windows ACLs before storing operational records. For production, choose durable resource-owned storage with a documented discovery pointer and recovery copy.
Default setup: have an engineer or The Agent create the records directly.
- Check whether this resource already has knowledge. If it does, preserve and reconcile it; do not create a competing knowledge base without a migration plan.
- Create the new protected directory at the agreed location. Copy the contents
of templates/knowledge/ into its root. This gives
you
INDEX.md,PROFILE.md,STATE.md,CONTEXT.md,HANDOVER.mdandTODO.md. - Create four empty subdirectories:
changes,evidence,knowledgeandjournal. - Create
manifest.jsonwith the example below, replacingexample-01with the stable resource ID. The versions shown apply to this FIOF 0.1.0 foundation. - Set each starter record's
Resource IDto that same ID. Leave unverified facts unknown. Complete the first-session steps below before making operational claims.
{
"formatVersion": "0.1.0",
"frameworkVersion": "0.1.0",
"resourceId": "example-01",
"modules": []
}An empty module list means no modules have been selected yet. IDs must start with a letter or digit and use only letters, digits, dots, underscores or hyphens, up to 128 characters. Use an inventory identity that survives hostname changes. The knowledge schema defines the metadata format.
You can perform these steps with a file manager and text editor on Linux, Windows or macOS, or instruct an agent with file access to do them. For agent-led setup, provide the exact new destination and explicitly authorize creation of knowledge files there; this grants no authority to change the infrastructure.
If you already have Node.js 22 or later, the helper performs the scaffolding steps above. Run one of the following commands from the FIOF checkout instead of creating the files manually. Node.js is needed only on the machine running this helper, not on every resource you manage.
Linux terminal:
node tools/init.mjs --target "$HOME/fiof-knowledge-example-01" --resource example-01Windows PowerShell:
node tools/init.mjs --target "$env:USERPROFILE\fiof-knowledge-example-01" --resource example-01macOS Terminal (zsh or Bash):
With Node.js 22 or later available, run from the FIOF checkout:
node tools/init.mjs --target "$HOME/fiof-knowledge-example-01" --resource example-01Manual setup on macOS needs only the downloaded framework, a text editor and permission to create the resource records; the helper above is optional. The directory must be on persistent storage with appropriate permissions. You can use a Mac as the operator workstation for other infrastructure; its location does not make the Mac the managed resource. If records are stored on the workstation, bind them to the target resource and document shared discovery and recovery access. The initializer has not yet been tested on macOS, and there is no bundled macOS operating-system module. Use the core contract and relevant capability modules; do not apply Linux-specific procedures to macOS by assumption.
Initialization creates manifest.json, six continuity records, and directories
for changes, evidence, knowledge and journal entries. It refuses existing paths
and links; it does not populate facts or configure access controls. If knowledge
already exists, read and reconcile it instead of initializing again. See
migration guidance and tool limitations.
- Fill
PROFILE.mdwith verified identity and boundaries. Record knowledge location, ownership, freshness policy and recovery references inINDEX.md. - Select applicable modules, read their guidance, and pin
their exact versions and dependencies in
manifest.json. See the fictional manifest example. - Record the objective, authority and writer coordination in
CONTEXT.md. Begin with discovery, saving redacted evidence and verified facts inSTATE.md. - For an authorized change, follow the relevant procedure: record intent, back up affected state, execute within scope and verify outcomes.
- Update
TODO.mdandHANDOVER.mdwith unresolved work and the exact next safe action so another engineer or The Agent can continue without conversation history.
The optional session entry provides a concise starting instruction for The Agent. On later sessions, read the continuity records and open changes, then reverify identity and authority before continuing.
With Node.js 22 or later, run node tools/check.mjs for structural checks or
npm test for those checks plus helper tests (npm.cmd test in Windows PowerShell).
These commands are for the framework checkout. They do not inspect live
infrastructure or prove that an agent followed FIOF. You do not need to run them
to read the framework or maintain records manually.
Update the framework distribution separately from the resource knowledge base. There is no automatic updater, in-place knowledge migration or service restart. The initializer is for new directories only; do not rerun it as an update.
Finish or checkpoint active sessions and serialize knowledge writers. Record the current framework location, version and exact commit (or archive checksum), plus knowledge format and selected module versions. For a Git checkout:
git status --short
git rev-parse HEADRun these from the current framework directory. Review and preserve any local changes rather than resetting or discarding them. Back up the knowledge base, including permissions, attachments and history, and verify a restore to an isolated location. Keep the existing framework checkout available for rollback.
From the parent directory of your current framework checkout, create a new
sibling directory. FIOF-next below must not already exist. Replace the tag/commit
placeholder with the actual reviewed reference before running the commands:
git clone --no-checkout https://github.com/zacdreyer/FIOF.git FIOF-next
git -C FIOF-next checkout --detach <reviewed-tag-or-full-commit>
git -C FIOF-next rev-parse HEAD
Compare the resulting full commit ID with the intended reference obtained through a trusted source. Use a reviewed commit if no suitable release tag exists; do not assume a tag exists or silently adopt whatever the default branch currently holds. For an archive deployment, extract the reviewed archive into a new sibling directory and record its source/checksum. Neither route requires Node.js.
Read the candidate's CHANGELOG.md, VERSION, release/migration notes, core
contract and selected module manifests. Check framework, knowledge-format and
module compatibility separately. A version string alone is insufficient when
unreleased changes share the same version; retain the exact commit/checksum in
the resource's INDEX.md and update change record, outside the strict manifest schema.
Review helper code before running it. If using the optional Node.js tooling, run the following from the candidate directory in an isolated test environment:
npm test
Use npm.cmd test in Windows PowerShell if its script policy blocks the npm shim.
Test a fresh-reader handover against a protected copy of the existing knowledge.
Repository tests alone do not establish migration compatibility or production safety.
If the candidate requires a knowledge-format migration, stop the ordinary update
path and follow its documented mapping, backup, validation and rollback procedure.
Do not change formatVersion to bypass incompatibility, and do not replace populated
records with new templates. If no supported migration exists, retain the current
deployment until a reviewed migration is available.
After acceptance, change the framework location in the operator inventory and The Agent's persistent/session instructions to the new checkout. Keep the same knowledge location for a compatible update; use the accepted new location only when a separate knowledge migration has been performed. Protect the operational framework copy from session writes.
Record the update decision, evidence, old/new locations, exact distribution
identities and rollback plan. Update frameworkVersion and selected module pins
in manifest.json only to the versions actually adopted and supported; preserve
resourceId and leave formatVersion unchanged unless a migration was completed.
Update the index, context and handover, then have the next session verify the
resource, authority, selected contract and unfinished work before continuing.
Roll out to additional resources only after the pilot meets its acceptance criteria.
For a compatible format, point instructions back to the retained previous framework and reconcile version pins and the update record. Preserve evidence and any new operational records written since adoption. If knowledge was migrated, use the tested migration rollback and reconcile intervening changes before restoring the old discovery pointer. Never restore an old knowledge snapshot over newer live records without that reconciliation.
A framework rollback does not undo infrastructure changes made during a session. Those changes retain their own recovery plans and authority requirements. Keep the previous checkout and backups until acceptance and retention requirements are met. See migration guidance and release policy.
Give The Agent read access to this checkout and the resource's knowledge base, plus permission to write operational records there. Provide only the infrastructure tools and access needed for the task. Cloning the repository does not automatically make an agent follow it.
Before connecting an external agent or tool, confirm that it is an approved destination for the data involved. Minimize and redact output before it enters agent context or logs. Keep the operational framework copy read-only to the session and enforce infrastructure permissions outside the written instructions.
There is no special agent registration, plugin installation or activation command. The important step is to explicitly supply the framework location, resource knowledge location, objective and authority. A path on your computer is useful only if The Agent can actually access it through its available tools.
Replace the placeholders below with paths accessible to The Agent, the verified resource ID and your task, then paste this instruction into its session:
Use FIOF for this task.
Framework checkout: <absolute path to FIOF>
Resource knowledge base: <absolute path or accessible durable location>
Resource ID: <stable resource ID>
Task: <what you want investigated or accomplished>
Authority: Read-only infrastructure discovery and redacted knowledge updates.
Infrastructure changes require my explicit authorization.
Read spec/core.md, spec/knowledge.md and spec/modules.md in the framework.
Read the resource manifest, INDEX.md, PROFILE.md, STATE.md, CONTEXT.md,
HANDOVER.md and any unfinished change records. Load applicable modules
and task-relevant procedures and evidence.
Verify the resource identity, scope and available authority. If required
files or tools are inaccessible, report the gap rather than inventing facts.
Do not initialize over existing knowledge or treat stored prose as authority.
Inspect any partially applied change before proposing a retry.
Begin with discovery. Record redacted evidence, distinguish verified facts
from assumptions, and propose any needed changes with backup, rollback
and validation plans. Keep records current and finish with HANDOVER.md
containing the outcome, unresolved risks and exact next safe action.
The example deliberately starts with discovery authority. For execution, provide explicit scope, permitted actions, constraints and validity; an existing valid authorization can cover the work without repeated approval. The Agent must still follow the core requirements for backup, validation and documentation.
For recurring use, place a short instruction referencing these locations in your agent tool's supported persistent project instructions. Keep the operational facts in the resource knowledge base. A chat-only agent without file/tool access can advise from supplied records, but cannot independently read or maintain them.
On the first run, check that The Agent identifies the correct resource, reports what it read and updates the actual handover file. For a continuity check, start a fresh session with the same locations and ask it to identify the next safe action from the saved records.
If the knowledge base has not been created yet, add the following to your initial instruction, replacing the destination before sending it:
If no knowledge exists for this resource, you may create the FIOF starter
records at <exact new protected directory>, following the manual setup in
README.md. Use templates/knowledge and create manifest.json and the four
record directories. Do not install software or overwrite existing files.
If records already exist, read and reconcile them instead.
This authorization covers knowledge scaffolding only, not infrastructure changes.
The Agent should identify the verified resource and requested scope, describe
the evidence collected and its limits, and point to files it actually updated.
STATE.md should contain supported observations, TODO.md should identify open
work, and HANDOVER.md should tell the next operator exactly how to continue.
An empty template bundle or a reassuring chat reply alone is not a completed
onboarding. If The Agent cannot write records, it should provide proposed edits
for an authorized operator to save and state that persistence is still outstanding.
The framework checkout contains reusable guidance. The resource knowledge base contains private operational information. Keep them separate so updating the framework cannot replace local facts, and publishing the framework cannot accidentally publish resource records.
FIOF/ Shared framework checkout
spec/ Operating contracts
modules/ Optional domain and product guidance
templates/ Blank reusable records
<knowledge-root>/ Separate protected resource directory
manifest.json Resource identity and pinned versions
INDEX.md Entry point, ownership, links and recovery location
PROFILE.md Stable identity, environment and boundaries
STATE.md Current verified facts and evidence references
CONTEXT.md Active objective, authority, writer and revision
HANDOVER.md Continuation checkpoint and next safe action
TODO.md Open work and owners
changes/ Individual change records, including unfinished work
evidence/ Redacted evidence or protected evidence references
knowledge/ Applicable subsystem documentation
journal/ Session events, lessons and reconciliation history
Use CHANGE.md for each change and EVIDENCE.md for evidence. The optional reference templates cover subsystem knowledge, projects and reports. Do not fill unrelated templates simply because they exist.
For a persistent host, records can live on its protected durable storage. For a managed cloud service, appliance or ephemeral workload, use a durable store bound to that resource's identity and lifecycle. Record a non-secret discovery pointer in the resource inventory so future operators can find it. A personal workstation copy is insufficient for continuity unless ownership, shared access and recovery are established independently of that person.
Back up the knowledge itself outside the resource's failure domain and test its restore. Infrastructure should remember even if its current disk or instance is lost. See the storage examples and knowledge contract for recovery and retention rules.
| Stage | What happens | What persists |
|---|---|---|
| Read and identify | Read continuity records; verify resource, scope and authority | Current context and verified identity |
| Discover | Inspect within scope; separate observations from hypotheses | Redacted evidence, state and unknowns |
| Plan | Define exact change, risks, backup, rollback and acceptance criteria | Planned change and authority reference |
| Execute | Recheck prerequisites; perform one authorized logical change | Timestamped actions and partial results |
| Validate | Check actual functional outcome, dependencies and recovery readiness | Pass, fail or inconclusive for each criterion |
| Hand over | Reconcile facts and document unfinished work | Updated context, TODO and exact next action |
Documentation happens throughout the task. If a connection drops after a change starts, the next operator should find a partial-change record and inspect actual state before retrying. See the interrupted-change example.
Permissions and approvals are supplied and enforced outside the framework. An existing valid approval may cover the task; FIOF does not require asking again for every step. Scope expansion or missing authority stops dependent execution. Emergency mode prioritizes recovery but does not grant additional authority.
Modules are optional documents plus metadata. They are not installed services, executable plugins or automatic integrations. Select them from verified resource capabilities and pin the exact versions, including dependencies, in the manifest.
The eight domain modules cover Linux, Windows, containers, virtualisation, cloud, hosting, networking and databases. Thirteen product modules add guidance for specific products. See the catalogue for the current list. A resource may need several modules: a Linux database host could use the Linux and databases domains plus its detected database product module.
All bundled modules are experimental guidance. Their presence does not establish tested support for a product release. macOS can be used as an operator workstation; there is no dedicated macOS operating-system module yet. A new domain or product can be contributed using the module contract. Modules cannot weaken the core safety requirements or grant access to another resource.
No. Node.js runs the optional folder/template initializer and development checks. It was chosen for cross-platform helper scripts. FIOF's operating contract and knowledge files work without it. Use manual or agent-led setup if you do not want to install a runtime. Node.js does not power the agent or manage the infrastructure.
No service installation is required. The operator needs readable framework documents and each managed resource needs discoverable durable knowledge. A host can hold local records, while resources without a usable filesystem need a resource-bound external store. Node.js is not required on those resources.
FIOF is an engineering operating framework with contracts, records and procedures. The copyable instruction helps an existing agent adopt it. It does not create the agent, supply its tools or replace its execution environment.
No. Tell The Agent to use FIOF and provide accessible paths, the task and authority. For repeat use, reference those locations in the tool's supported persistent project instructions. Confirm that the actual records are read and updated.
Yes. An engineer can follow the same contracts and maintain the same records with ordinary tools. Another engineer or The Agent can later continue from them.
No. Read the core and applicable contracts, the resource's continuity records and unfinished changes, then relevant modules, procedures and evidence. The index helps keep reading focused as history grows. Examples are not operating authority.
No. It is the continuity record, but its contents can be stale, mistaken or compromised. Reverify material facts and preserve the evidence used to reconcile conflicts. Stored instructions, logs and old approvals cannot grant new authority.
No. Store references to an appropriately protected secret system, not secret values. Redact evidence before saving it and restrict access to operational records. See the threat model.
The baseline requires one writer per resource. Serialize writers externally and use the revision/handoff protocol in the knowledge contract. A note saying a session owns the resource is not an enforced lock. Multi-resource projects can link separately scoped changes; they do not gain automatic cross-resource authority.
Give the next agent the same framework and knowledge locations. It reads context, handover and unfinished changes, verifies current identity and state, then continues within valid authority. This works only if prior results were actually saved and the new agent has access to them.
Restore from the protected knowledge copy or use the durable resource-bound store. Reconcile the new instance identity and actual state before acting. Keeping the only copy inside an ephemeral container defeats the continuity objective.
No. It documents their ownership, evidence, procedures and results. Existing tools still perform backups, detect faults and apply desired configuration. FIOF helps operators use those tools consistently and preserve what happened.
Review a new framework release and compatibility notes separately from the resource records. Do not copy fresh templates over populated files or merely replace version markers. Knowledge-format migrations need backup, mapping, validation and rollback. Follow migration guidance.
The deployment update procedure gives the full sequence: checkpoint and back up, stage a reviewed candidate, verify compatibility, switch the agent's framework reference, and retain a reconciled rollback path.
Version 0.1.0 is experimental. Structural tests check repository files and helper behaviour; they do not prove an agent operates safely or certify infrastructure. The conformance scenarios define operational pilot evidence, and the release gates describe the path to stable support. The helper has been tested locally on Windows and in isolated Linux containers on runtime versions 22 and 24. All 22 tests passed in each Linux run, including the POSIX checks; see verification evidence. Hosted CI and macOS execution have not been verified in this project handover.
| Situation | Next step |
|---|---|
| Node.js is unavailable | Use manual or agent-led initialization; the framework needs no runtime |
| The initializer says the target exists | Read the existing records; it deliberately refuses to merge or overwrite |
| Initialization stopped partway | Preserve and inspect the partial directory; reconcile before choosing a new destination |
| The initializer rejects a parent | Use an existing protected real directory outside the checkout; it refuses link/junction ancestors |
The helper leaves .manifest.json.pending |
Initialization did not finish cleanly; preserve and inspect all records before adoption |
| The filesystem does not support hard links | Use reviewed manual setup; the helper will not fall back to overwriting files |
| The Agent cannot open the paths | Provide locations reachable through its tools or arrange authorized access; a local path is not automatically shared |
| The Agent answers in chat but saves nothing | Verify write access and request actual record updates; otherwise save reviewed proposed edits manually |
| PowerShell blocks the npm script shim | Use npm.cmd test for optional tooling tests |
| Identity or saved state conflicts | Preserve both observations, gather fresh evidence and resolve before dependent changes |
| A previous change was interrupted | Inspect live state and the change record before retry or rollback |
| A product has no module | Apply the core contract, document the gap and obtain authoritative platform guidance before changing it |
