fcontext

Context continuity across AI agents & sessions. Team knowledge collaboration. Industrial-grade AI delivery.

---

The Problem

AI coding agents are powerful, but they forget everything between sessions, lose all context when you switch agents, and have no way to share knowledge across a team. Every conversation starts from zero.

WITHOUT fcontext

  Session 1 (Copilot): "Build the auth module"
  Session 2 (Claude):  "What auth module? I don't see any context."
  Session 3 (Cursor):  "Can you explain the project first?"
  Teammate's Agent:    "I have no idea what your team has decided."

  Result: Repeated explanations. Inconsistent output. Wasted tokens.

WITH fcontext

  Session 1 (Copilot): "Build the auth module" -> saves context
  Session 2 (Claude):  Reads _README.md + _topics/ -> picks up work
  Session 3 (Cursor):  Knows the full project, requirements, history
  Teammate's Agent:    Imports experience pack -> instant onboarding

  Result: Continuous context. Consistent quality. Industrial output.

Why fcontext

For Individuals

AI delivers results, but you deliver process and experience.

Your expertise — how you approach problems, what patterns you've learned, what pitfalls to avoid — is lost every time a session ends. fcontext captures and persists that experience, so your AI gets smarter with every interaction.

• Cross-session memory — Topics and conclusions survive between conversations
• Cross-agent portability — Switch from Copilot to Claude to Cursor without losing context
• Experience visualization — Your accumulated knowledge becomes a structured, reusable asset

For Teams & Enterprises

No single agent has all the context to do the job. Real work is distributed.

In production environments, context is fragmented: requirements live in documents, domain knowledge lives in people's heads, architecture decisions live in past conversations. fcontext solves distributed context.

• Team knowledge sync — Export/import experience packs so every team member's agent shares the same domain understanding
• Requirements traceability — Track stories, tasks, bugs with full evolution history — from document to delivery
• Compliance-ready — All data stored locally in .fcontext/, no cloud dependency, fully offline capable
• Industrial-grade delivery — Structured context + requirements tracking + document indexing = consistent, auditable AI output

Installation

Prerequisites

• Python 3.9+
• pip

Install from PyPI

pip install fcontext

Verify

fcontext --version
# fcontext 1.0.0

---

Quick Start

# 1. Initialize in any project
cd your-project
fcontext init

# 2. Activate your AI agent
fcontext enable copilot    # or: claude, cursor, codex, trae, qwen, kiro, opencode, openclaw, zed, pi, antigravity

# 3. Index your documents
fcontext index docs/

# 4. Check status
fcontext status

That's it. Your AI agent now reads project context automatically on every session.

---

Use Cases

Scenario 1: Picking Up Where You Left Off

Problem: You had a deep debugging session yesterday. Today, a new session knows nothing.

# fcontext automatically persists session knowledge to _topics/
# Next session reads _topics/ and _README.md first

# To see what was saved:
fcontext topic list
fcontext topic show debugging-auth-flow

The new session starts with full context of yesterday's findings.

Scenario 2: Switching Between Agents

Problem: You used Cursor for frontend work but need Claude for backend refactoring. Claude has no idea what Cursor did.

# Enable both agents — they share the same .fcontext/ data
fcontext enable cursor
fcontext enable claude

# Both agents read the same _README.md, _topics/, _requirements/
# Context is agent-agnostic

Scenario 3: Onboarding a New Team Member

Problem: A new developer joins. Their AI has zero project knowledge.

# Team lead exports accumulated knowledge
fcontext export team-knowledge.zip

# New member imports it
fcontext experience import team-knowledge.zip

# Their AI instantly knows: architecture, domain concepts, conventions, pitfalls
fcontext experience list

Scenario 4: Working with Binary Documents

Problem: Product specs are in PDF/DOCX. AI cannot read them.

# Convert to Markdown so any agent can read them
fcontext index specs/product-requirements.pdf
fcontext index contracts/

# AI now references the content directly from _cache/
fcontext status

Scenario 5: Requirements-Driven Development

Problem: Requirements are scattered across documents, Slack, and meetings. AI builds the wrong thing.

# Structure requirements in fcontext
fcontext req add "User authentication via OAuth" -t story
fcontext req add "Support Google and GitHub providers" -t task --parent STORY-001
fcontext req set TASK-001 status in-progress

# AI reads _requirements/ and builds against tracked specs
fcontext req board    # Kanban view
fcontext req tree     # Hierarchy view

Scenario 6: Sharing Domain Expertise Across Projects

Problem: You've built deep domain knowledge in Project A. Project B needs the same expertise.

# In Project A: export to a git repo
fcontext export git@github.com:team/domain-knowledge.git

# In Project B: import as experience pack
fcontext experience import git@github.com:team/domain-knowledge.git

# Keep it updated
fcontext experience update

How It Works

your-project/
  .fcontext/                        # All context data (git-tracked)
    _README.md                      # AI-maintained project summary
    _workspace.map                  # Auto-generated structure
    _index.json                     # File index registry
    _cache/                         # Converted documents (Markdown)
    _topics/                        # Session knowledge & conclusions
    _requirements/                  # Stories, tasks, bugs
      items.csv                     # Structured data
      _backlog.md                   # Auto-generated summary
      docs/                         # Per-item details
    _experiences/                   # Imported domain knowledge (read-only)
      <pack-name>/
        _README.md
        _cache/
        _topics/

  .github/instructions/             # Copilot (auto-generated by fcontext enable)
  .claude/rules/                    # Claude (auto-generated)
  .cursor/rules/                    # Cursor (auto-generated)
  AGENTS.md                         # Codex (auto-generated)
  .codex/skills/                    # Codex skills (auto-generated)
  .trae/rules/                      # Trae (auto-generated)

Each AI agent gets instructions in its native format. The instructions teach the agent to:

1. Read .fcontext/_README.md first to understand the project
2. Check _cache/ before trying to read binary files
3. Use fcontext req commands for requirements (never parse CSV manually)
4. Save important conclusions to _topics/ for future sessions
5. Read _experiences/ for imported domain knowledge

• Every new feature needs tests
• Keep from __future__ import annotations in all modules (Python 3.9 compat)
• CLI commands should give clear error messages when .fcontext/ is not initialized
• Experience packs under _experiences/ are always read-only
