compact-memory-implementation

A developer guide for building compact memory into an Agent: detect when to compress, fork a compactor sub-agent, produce a structured summary, and restore it in the next session.

Step 1 — Understand the setup

Before designing anything, clarify:

SDK / language: Claude Agent SDK? Direct Anthropic API? Python or TypeScript?
Agent architecture: single-agent loop, multi-agent, tool-calling?
Session model: one long-running session or multiple short sessions?
What must survive compaction: task state, decisions, tool results, conversation history?

This determines which pattern fits.

Step 2 — When to trigger compact

Three strategies, pick based on your session model:

1. Token threshold (recommended) Check usage.input_tokens from the previous response. When it exceeds ~70–80% of your model's context limit, trigger compact.

COMPACT_THRESHOLD = 150_000  # adjust per model

if response.usage.input_tokens > COMPACT_THRESHOLD:
    compact = compact_memory(history)
    history = []  # reset — compact moves to system prompt

2. Turn count Compact every N turns. Simpler but less adaptive — misses sessions with a few very long turns.

COMPACT_EVERY_N = 30

if turn_count % COMPACT_EVERY_N == 0:
    compact = compact_memory(history)

3. Phase boundary Compact at natural task boundaries (after research, before implementation). Requires the agent to detect phases. Produces summaries that align with meaningful milestones, but harder to implement reliably.

Recommended default: token threshold at 70%, with turn-count fallback at N=40.

Step 3 — Fork agent for compaction

The compactor is a separate agent call whose only job is to read the current state and return a structured summary. Fork it synchronously — the main agent waits for the result before continuing.

def compact_memory(history: list[dict]) -> dict:
    response = client.messages.create(
        model="claude-haiku-4-5-20251001",  # cheaper model is fine for compaction
        max_tokens=4096,
        system=COMPACTOR_SYSTEM_PROMPT,
        messages=[
            {
                "role": "user",
                "content": format_history_for_compact(history),
            }
        ],
    )
    return json.loads(response.content[0].text)

Why fork instead of self-compact:

The main agent may have drifted in focus; the compactor starts fresh with the full picture
Compaction is a different cognitive task — summarizing vs. executing
A cheaper, smaller model (Haiku) can do compaction; save the expensive model for main work
Clean separation makes the compact output easier to validate and test

Step 4 — How to compact: format and prompt

Compact output schema

{
  "task": "What the agent is working on and why — the goal, not the steps",
  "current_state": "Exact status at compaction point: what is done, what is not, what is in progress",
  "key_decisions": [
    { "decision": "...", "reason": "...", "constraint": "..." }
  ],
  "eliminated_approaches": [
    { "approach": "...", "reason_ruled_out": "..." }
  ],
  "open_questions": ["..."],
  "next_steps": ["..."],
  "relevant_tool_results": {
    "key": "Only results future steps will need — summarized, not raw dumps"
  },
  "compacted_at_turn": 42
}

Compactor system prompt

You are a conversation compactor. Read the provided conversation and produce a JSON summary that captures everything a fresh agent needs to continue the work without asking what happened.

Include:
- Current task and goal (not the steps taken to get here)
- Exact current state — what is done and what is not
- Decisions made and WHY (reasoning, not just the choice)
- Approaches tried and ruled out with reasons (prevents re-exploration)
- Open questions and blockers
- Concrete next steps in priority order
- Tool results that future steps will need (summarize, don't dump raw output)

Omit:
- Intermediate reasoning that led nowhere
- Completed sub-tasks with no future relevance
- Raw tool output that has already been acted on
- Anything derivable by reading the code or running a command

Output valid JSON matching the schema provided. No prose outside the JSON.

Format history for compactor

def format_history_for_compact(history: list[dict]) -> str:
    lines = ["Conversation to compact:\n"]
    for msg in history:
        role = msg["role"].upper()
        content = msg["content"] if isinstance(msg["content"], str) else "[tool use]"
        lines.append(f"[{role}]: {content[:2000]}")  # cap very long messages
    return "\n".join(lines)

Step 5 — How to use after compacting: memory restoration

The compact object becomes the "memory" for the next turn or session. Inject it into the system prompt so it's always visible to the agent.

Pattern A — System prompt injection (recommended)

MEMORY_BLOCK_TEMPLATE = """
## Restored memory (compacted at turn {turn})

**Task**: {task}

**Current state**: {current_state}

**Key decisions**:
{decisions}

**Ruled out approaches**:
{eliminated}

**Next steps**:
{next_steps}

Begin from current state above. Do not re-explore eliminated approaches.
"""

def build_system_with_memory(base_system: str, compact: dict | None) -> str:
    if compact is None:
        return base_system
    memory = MEMORY_BLOCK_TEMPLATE.format(
        turn=compact["compacted_at_turn"],
        task=compact["task"],
        current_state=compact["current_state"],
        decisions="\n".join(f"- {d['decision']} (because {d['reason']})"
                            for d in compact["key_decisions"]),
        eliminated="\n".join(f"- {e['approach']}: {e['reason_ruled_out']}"
                             for e in compact["eliminated_approaches"]),
        next_steps="\n".join(f"- {s}" for s in compact["next_steps"]),
    )
    return base_system + "\n\n" + memory

Pattern B — First message injection (for stateless API callers)

messages = [
    {
        "role": "user",
        "content": f"[Resuming from compacted state — turn {compact['compacted_at_turn']}]\n"
                   f"{json.dumps(compact, indent=2)}\n\n"
                   f"Continue from the next steps listed above.",
    }
]

Persistence across sessions

import json, pathlib

MEMORY_DIR = pathlib.Path("memory")
MEMORY_DIR.mkdir(exist_ok=True)

def save_compact(session_id: str, compact: dict) -> None:
    (MEMORY_DIR / f"{session_id}.json").write_text(json.dumps(compact, indent=2))

def load_compact(session_id: str) -> dict | None:
    path = MEMORY_DIR / f"{session_id}.json"
    return json.loads(path.read_text()) if path.exists() else None

Step 6 — Full agent loop

def run_agent(session_id: str, user_input: str) -> str:
    compact = load_compact(session_id)
    system = build_system_with_memory(BASE_SYSTEM, compact)
    history = []
    turn = 0

    while True:
        response = client.messages.create(
            model="claude-opus-4-7",
            system=system,
            messages=history + [{"role": "user", "content": user_input}],
            max_tokens=8192,
        )

        # Trigger compact if context is growing too large
        if response.usage.input_tokens > COMPACT_THRESHOLD:
            compact = compact_memory(history)
            save_compact(session_id, compact)
            system = build_system_with_memory(BASE_SYSTEM, compact)
            history = []  # reset history — compact is now in system
            turn = 0
            continue

        if response.stop_reason == "end_turn":
            return response.content[0].text

        history.append({"role": "assistant", "content": response.content})
        user_input = handle_tool_calls(response)  # your tool dispatch
        turn += 1

Step 7 — Chaining compacts across sessions

If a session resumes multiple times, don't stack compacts — re-compact instead:

COMPACTOR_WITH_PRIOR = """
You are updating an existing memory compact with new information from a continuation session.

Prior compact:
{prior_compact}

New conversation turns since last compact:
{new_turns}

Produce an updated compact that:
- Merges both sources
- Removes resolved items and completed steps
- Adds new decisions, eliminations, and open questions
- Keeps next_steps current

Output valid JSON. No prose outside the JSON.
"""

def compact_memory_with_prior(history: list[dict], prior: dict) -> dict:
    prompt = COMPACTOR_WITH_PRIOR.format(
        prior_compact=json.dumps(prior, indent=2),
        new_turns=format_history_for_compact(history),
    )
    response = client.messages.create(
        model="claude-haiku-4-5-20251001",
        max_tokens=4096,
        system=prompt,
        messages=[{"role": "user", "content": "Update the compact."}],
    )
    return json.loads(response.content[0].text)

Common pitfalls

Pitfall	Fix
Compact loses tool results needed later	Include summarized results in `relevant_tool_results`
Fresh session ignores compact	Inject into system prompt, not buried in messages
Compactor uses the same expensive model	Use Haiku for compaction, Opus for main work
Compact grows unbounded across sessions	Re-compact using "chaining compacts" pattern above
Compacting too often (every turn)	Use token threshold, not turn frequency
Compact JSON fails to parse	Add retry with explicit error feedback to compactor

# compact-memory-implementation

A developer guide for building compact memory into an Agent: detect when to compress, fork a compactor sub-agent, produce a structured summary, and restore it in the next session.

## Step 1 — Understand the setup

Before designing anything, clarify:

- **SDK / language**: Claude Agent SDK? Direct Anthropic API? Python or TypeScript?
- **Agent architecture**: single-agent loop, multi-agent, tool-calling?
- **Session model**: one long-running session or multiple short sessions?
- **What must survive compaction**: task state, decisions, tool results, conversation history?

This determines which pattern fits.

## Step 2 — When to trigger compact

Three strategies, pick based on your session model:

**1. Token threshold** (recommended)
Check `usage.input_tokens` from the previous response. When it exceeds ~70–80% of your model's context limit, trigger compact.

```python
COMPACT_THRESHOLD = 150_000  # adjust per model

if response.usage.input_tokens > COMPACT_THRESHOLD:
    compact = compact_memory(history)
    history = []  # reset — compact moves to system prompt
```

**2. Turn count**
Compact every N turns. Simpler but less adaptive — misses sessions with a few very long turns.

```python
COMPACT_EVERY_N = 30

if turn_count % COMPACT_EVERY_N == 0:
    compact = compact_memory(history)
```

**3. Phase boundary**
Compact at natural task boundaries (after research, before implementation). Requires the agent to detect phases. Produces summaries that align with meaningful milestones, but harder to implement reliably.

**Recommended default**: token threshold at 70%, with turn-count fallback at N=40.

---

## Step 3 — Fork agent for compaction

The compactor is a **separate agent call** whose only job is to read the current state and return a structured summary. Fork it synchronously — the main agent waits for the result before continuing.

```python
def compact_memory(history: list[dict]) -> dict:
    response = client.messages.create(
        model="claude-haiku-4-5-20251001",  # cheaper model is fine for compaction
        max_tokens=4096,
        system=COMPACTOR_SYSTEM_PROMPT,
        messages=[
            {
                "role": "user",
                "content": format_history_for_compact(history),
            }
        ],
    )
    return json.loads(response.content[0].text)
```

**Why fork instead of self-compact:**
- The main agent may have drifted in focus; the compactor starts fresh with the full picture
- Compaction is a different cognitive task — summarizing vs. executing
- A cheaper, smaller model (Haiku) can do compaction; save the expensive model for main work
- Clean separation makes the compact output easier to validate and test

---

## Step 4 — How to compact: format and prompt

### Compact output schema

```json
{
  "task": "What the agent is working on and why — the goal, not the steps",
  "current_state": "Exact status at compaction point: what is done, what is not, what is in progress",
  "key_decisions": [
    { "decision": "...", "reason": "...", "constraint": "..." }
  ],
  "eliminated_approaches": [
    { "approach": "...", "reason_ruled_out": "..." }
  ],
  "open_questions": ["..."],
  "next_steps": ["..."],
  "relevant_tool_results": {
    "key": "Only results future steps will need — summarized, not raw dumps"
  },
  "compacted_at_turn": 42
}
```

### Compactor system prompt

```
You are a conversation compactor. Read the provided conversation and produce a JSON summary that captures everything a fresh agent needs to continue the work without asking what happened.

Include:
- Current task and goal (not the steps taken to get here)
- Exact current state — what is done and what is not
- Decisions made and WHY (reasoning, not just the choice)
- Approaches tried and ruled out with reasons (prevents re-exploration)
- Open questions and blockers
- Concrete next steps in priority order
- Tool results that future steps will need (summarize, don't dump raw output)

Omit:
- Intermediate reasoning that led nowhere
- Completed sub-tasks with no future relevance
- Raw tool output that has already been acted on
- Anything derivable by reading the code or running a command

Output valid JSON matching the schema provided. No prose outside the JSON.
```

### Format history for compactor

```python
def format_history_for_compact(history: list[dict]) -> str:
    lines = ["Conversation to compact:\n"]
    for msg in history:
        role = msg["role"].upper()
        content = msg["content"] if isinstance(msg["content"], str) else "[tool use]"
        lines.append(f"[{role}]: {content[:2000]}")  # cap very long messages
    return "\n".join(lines)
```

---

## Step 5 — How to use after compacting: memory restoration

The compact object becomes the "memory" for the next turn or session. Inject it into the system prompt so it's always visible to the agent.

### Pattern A — System prompt injection (recommended)

```python
MEMORY_BLOCK_TEMPLATE = """
## Restored memory (compacted at turn {turn})

**Task**: {task}

**Current state**: {current_state}

**Key decisions**:
{decisions}

**Ruled out approaches**:
{eliminated}

**Next steps**:
{next_steps}

Begin from current state above. Do not re-explore eliminated approaches.
"""

def build_system_with_memory(base_system: str, compact: dict | None) -> str:
    if compact is None:
        return base_system
    memory = MEMORY_BLOCK_TEMPLATE.format(
        turn=compact["compacted_at_turn"],
        task=compact["task"],
        current_state=compact["current_state"],
        decisions="\n".join(f"- {d['decision']} (because {d['reason']})"
                            for d in compact["key_decisions"]),
        eliminated="\n".join(f"- {e['approach']}: {e['reason_ruled_out']}"
                             for e in compact["eliminated_approaches"]),
        next_steps="\n".join(f"- {s}" for s in compact["next_steps"]),
    )
    return base_system + "\n\n" + memory
```

### Pattern B — First message injection (for stateless API callers)

```python
messages = [
    {
        "role": "user",
        "content": f"[Resuming from compacted state — turn {compact['compacted_at_turn']}]\n"
                   f"{json.dumps(compact, indent=2)}\n\n"
                   f"Continue from the next steps listed above.",
    }
]
```

### Persistence across sessions

```python
import json, pathlib

MEMORY_DIR = pathlib.Path("memory")
MEMORY_DIR.mkdir(exist_ok=True)

def save_compact(session_id: str, compact: dict) -> None:
    (MEMORY_DIR / f"{session_id}.json").write_text(json.dumps(compact, indent=2))

def load_compact(session_id: str) -> dict | None:
    path = MEMORY_DIR / f"{session_id}.json"
    return json.loads(path.read_text()) if path.exists() else None
```

---

## Step 6 — Full agent loop

```python
def run_agent(session_id: str, user_input: str) -> str:
    compact = load_compact(session_id)
    system = build_system_with_memory(BASE_SYSTEM, compact)
    history = []
    turn = 0

    while True:
        response = client.messages.create(
            model="claude-opus-4-7",
            system=system,
            messages=history + [{"role": "user", "content": user_input}],
            max_tokens=8192,
        )

        # Trigger compact if context is growing too large
        if response.usage.input_tokens > COMPACT_THRESHOLD:
            compact = compact_memory(history)
            save_compact(session_id, compact)
            system = build_system_with_memory(BASE_SYSTEM, compact)
            history = []  # reset history — compact is now in system
            turn = 0
            continue

        if response.stop_reason == "end_turn":
            return response.content[0].text

        history.append({"role": "assistant", "content": response.content})
        user_input = handle_tool_calls(response)  # your tool dispatch
        turn += 1
```

---

## Step 7 — Chaining compacts across sessions

If a session resumes multiple times, don't stack compacts — re-compact instead:

```python
COMPACTOR_WITH_PRIOR = """
You are updating an existing memory compact with new information from a continuation session.

Prior compact:
{prior_compact}

New conversation turns since last compact:
{new_turns}

Produce an updated compact that:
- Merges both sources
- Removes resolved items and completed steps
- Adds new decisions, eliminations, and open questions
- Keeps next_steps current

Output valid JSON. No prose outside the JSON.
"""

def compact_memory_with_prior(history: list[dict], prior: dict) -> dict:
    prompt = COMPACTOR_WITH_PRIOR.format(
        prior_compact=json.dumps(prior, indent=2),
        new_turns=format_history_for_compact(history),
    )
    response = client.messages.create(
        model="claude-haiku-4-5-20251001",
        max_tokens=4096,
        system=prompt,
        messages=[{"role": "user", "content": "Update the compact."}],
    )
    return json.loads(response.content[0].text)
```
