Project continuity for coding agents

# Your coding agent should know why the code looks like this.

A fresh agent can read the repository. Give it the decisions, constraints and investigations that explain the code before it starts changing it.

[Start with Premium — $14.99/mo](/signup?target=ai-coding-agent-memory&plan=premium&interval=month) [Find your client setup guide](/developers/mcp-client-setup?target=ai-coding-agent-memory)

Premium includes 2,000 MCP operations and 25,000 hosted-intelligence credits per month.

1.  Project notes / ADRs / research / decisions
    
    The history behind the repository
    
2.  Phasoric durable context
    
    Only the knowledge you authorize
    
3.  Codex / Claude Code / Cursor / Copilot
    
    Retrieve context → implement with client permissions
    
4.  Reviewed decision / write-back
    
    Approve the note → better context for the next agent
    

Ask for context before action

## The next task starts with the reasoning.

> “Read the implementation brief and related decisions in my Phasoric Vault. Summarize the constraints and rejected approaches with source paths before changing code.”

The brief, the repository and the agent stay distinct. Phasoric supplies authorized knowledge; your coding agent uses its own workspace permissions to implement the change.

1.  01
    
    ### Keep the missing history
    
    Save architecture decisions, implementation briefs, rejected approaches, incident history, requirements, constraints, deployment decisions and known technical debt.
    
2.  02
    
    ### Retrieve before implementing
    
    Ask the agent to find the relevant records and previous investigations. Check the source paths and unresolved questions before accepting a plan.
    
3.  03
    
    ### Review the next decision
    
    After implementation, review a proposed decision note and approve its write-back separately. The next agent can retrieve that updated record.
    

From our own work · September 2026

## A plan in the Vault became a working change.

We asked Codex to read a Phasoric Vault brief about persistent MCP connections. It retrieved the plan through Phasoric, investigated the OAuth flow, and implemented the fix in the repository. The reasoning traveled with the task.

1.  01
    
    ### Read the brief
    
    An existing Markdown plan supplied the problem, constraints, and acceptance criteria.
    
2.  02
    
    ### Investigate and implement
    
    Codex used the brief to guide the code changes and tests in the project.
    
3.  03
    
    ### Review and merge
    
    The fix was merged into develop after approval, with release validation still explicit.
    

Explore the workflow

What did we decide?What changed?Write this decision back.

Read the context. Do the work. Save the reasoning for next time.

Recover the rationale

Keep access tokens short-lived. Use rotating refresh tokens so an authorized agent can renew access silently. Keep vault-provider credentials behind Phasoric.

Source: Persistent MCP OAuth brief · requirements and constraints

The agent reads the original plan and its reasoning before proposing a change.

Use the client’s own workflow

## A brief for Codex. A decision trail for Claude Code.

### Codex: start from the implementation brief

Connect Phasoric on the host where the task runs. In a fresh task, ask Codex to read the brief, name its constraints and inspect the repository before editing. After review, propose the outcome as a separate decision-note update.

Adding the URL and authenticating are separate steps. MCP knowledge access grants no repository or deployment authority.

[Set up Codex](/developers/mcp-codex?target=ai-coding-agent-memory)

### Claude Code: recover the rejected approach

Use the documented remote HTTP setup, then inspect and authenticate the connection with /mcp. Try: “Find the ADR for this subsystem. Which approach did we reject, and why? Cite the source before suggesting the same change again.”

This is a suggested workflow, not a recorded Phasoric interoperability test. Claude’s remote connector and Claude Code use different setup paths.

Durable context. Deliberate access.

## Keep control of the record.

Phasoric exposes the knowledge you authorize. It does not silently ingest every conversation or automatically remember everything your agents do.

-   ### Choose the source
    
    Hosted MCP reaches explicitly mapped Phasoric Hosted, Dropbox, Google Drive or GitHub vaults. Local-only vaults and device-encrypted remote bodies remain unavailable.
    
-   ### Keep the provenance
    
    Ask for the note path, evidence and limits of the answer. Your Markdown remains portable across tools.
    
-   ### Approve the write
    
    Review a proposed note change before application. Write permission, current-content checks and duplicate-request safeguards still apply.
    

Documented client setup

## Start in the tool you already use.

An authenticated Vault read was verified in Codex. The other guides describe documented setup paths; client plans, versions and workspace policies determine availability. They do not establish Phasoric interoperability for every client version.

### More remote MCP setup paths

OpenClaw, Hermes Agent and Grok document remote MCP connection paths. These guides map those instructions to Phasoric; authenticated interoperability has not been verified for these clients.

## Before you begin

Does this replace repository instructions?

No. Repository instructions still guide work in that checkout. Phasoric supplies the authorized project history, research and decisions that may live outside it. Ask the agent to retrieve that context explicitly.

Does every coding session save itself?

No. Phasoric does not silently ingest agent conversations or repository changes. Save the useful outcome and rationale as a reviewed note if you want a future task to retrieve it.

What has been verified with Codex?

An authenticated Phasoric Vault read supplied the persistent-MCP brief used in our real Codex investigation and implementation. This is evidence for that workflow, not proof of every client version or unattended deployment.

Start with one project

## Give the next session something to build on.

Keep the brief, recover the evidence and save the reviewed decision. Choose how you want to use that context.

### Use it through MCP

Connect the AI tools you already use to your authorized Phasoric knowledge. Hosted MCP starts with Premium.

$14.99/month includes 2,000 MCP operations and 25,000 hosted-intelligence credits each month. Higher plans increase limits and features.

[Connect my AI tools](/signup?target=ai-coding-agent-memory&plan=premium&interval=month)

### Use hosted intelligence

No MCP setup required. Ask Phasoric directly using hosted intelligence with bounded relevant source context.

Eligible Free hosted accounts can buy 50,000 credits for $5.99. Usage is metered; a credit pack does not enable MCP.
