# Jev context pruning — independent plugin example
|
||||
|
||||
An opt-in Python plugin that uses Jev to shorten clearly obsolete **read-only
|
||||
tool results** before DeerFlow's normal summarization. It uses the existing
|
||||
extension API 0.2.2 and full-stack plugin catalog, with no host code changes.
|
||||
Distributed under DeerFlow's [MIT license](LICENSE).
|
||||
|
||||
## Install and configure
|
||||
|
||||
From `backend/` in a compatible DeerFlow deployment:
|
||||
|
||||
```sh
|
||||
uv run deerflow extensions install ../examples/deerflow-extension-jev-context --yes
|
||||
export TYPESAFE_API_KEY='your-deployment-secret'
|
||||
```
|
||||
|
||||
Set the registered entry in the deployment configuration:
|
||||
|
||||
```yaml
|
||||
plugins:
|
||||
- use: deerflow_extension_jev_context:install
|
||||
enabled: true
|
||||
config:
|
||||
enabled: true
|
||||
trigger_tokens: 60000
|
||||
min_calls_between_attempts: 16
|
||||
```
|
||||
|
||||
Provide the environment variable to the actual Gateway process (including its
|
||||
container, if applicable). Restart Gateway after installing or changing deployment
|
||||
configuration; refresh Capability Center to see **Jev context pruning**. The outer
|
||||
switch loads the package; `config.enabled` enables its middleware and contribution.
|
||||
It is disabled by default. The plugin catalog is read-only; there is no online
|
||||
key editor, custom browser page, or new slash command. The authenticated `status`
|
||||
backend action reports enabled/configured/threshold without exposing credentials.
|
||||
`configured` means the key environment variable is nonempty, not that authentication
|
||||
or connectivity has been verified.
|
||||
No frontend rebuild is required.
|
||||
|
||||
**Deployment opt-in sends bounded conversation excerpts, recent user goals,
|
||||
read-tool arguments and result samples to `https://api.typesafe.ai/v1/systemone`.**
|
||||
The service uses `jev-latest` and typed `noul` decisions. This is a separate API
|
||||
from the main chat model; a free main model does not make Jev free. Keys are read
|
||||
only from the named environment variable, never from plugin settings or messages.
|
||||
|
||||
## Behavior and limits
|
||||
|
||||
- Runs on the lead agent through `before_model` / `abefore_model` at
|
||||
`MODEL_LOGICAL`. No subagent interception or provider retry multiplier.
|
||||
- Only considers old, successful, plain-text results of `read_file`, `grep`,
|
||||
`glob` and `ls`. Calls/results must match unambiguously with stable message IDs.
|
||||
Protects the first message, newest six messages, skill reads, errors, multimodal
|
||||
outputs, assistant text, users, and all tool-call records. Write/bash/task and
|
||||
other tools are never candidates. Deployments must preserve the read-only
|
||||
meaning of these built-in names.
|
||||
Host-stamped errors, partial results and unknown/malformed structured outcomes
|
||||
are protected even when LangChain's message status still says `success`.
|
||||
- A result is shortened only when its keep probability is below 0.2. Preserves
|
||||
300 characters at each end plus an explicit omission note. Samples cannot
|
||||
prove that the omitted middle is irrelevant: **this is lossy**, and historical
|
||||
source contents may not be reproducible by reading again.
|
||||
- Applies a batch only when estimated total context reduction reaches 10%.
|
||||
Sends at most eight candidates in one request, capped at 24,000 UTF-8 bytes
|
||||
including question instructions. Oversized candidates are skipped while later,
|
||||
smaller candidates can still fit in the same request. It does not repeatedly
|
||||
call Jev to process the entire conversation.
|
||||
- Replaces result contents under their existing IDs in the **persisted graph
|
||||
state**. Disabling the plugin does not restore omitted text. It creates no
|
||||
transcript archive. Existing message metadata and call/result pairing remain.
|
||||
Replacements carry `jev_context_shortened: true` in their additional metadata,
|
||||
but no original-to-replacement hash mapping or detailed audit event is retained.
|
||||
Extension API 0.2.2 exposes `CompactionEvent` and observer registration, but no
|
||||
public event-emission API for this middleware; this plugin does not notify those
|
||||
observers through host internals. The marker identifies a shortened message but
|
||||
cannot reconstruct omitted facts or explain the classifier's decision.
|
||||
- HTTP failures, missing/invalid answers, missing keys or insufficient reduction
|
||||
leave messages unchanged. The host's usual summarization remains available.
|
||||
Cancellation propagates. There are no automatic Jev retries or payload logs.
|
||||
For caught request/response failures, the
|
||||
`deerflow_extension_jev_context.compaction` logger emits a DEBUG message containing
|
||||
only the exception class. Enable that logger to diagnose failures; the plugin
|
||||
never includes exception text, tracebacks, URLs, credentials or conversation data
|
||||
in these diagnostics.
|
||||
- After an attempt (including failure/no change), skips the next 16 logical model
|
||||
calls before trying again (attempts at calls 1, 18, 35, ...). This cooldown is
|
||||
checkpointed per thread, so a shared agent instance does not mix users' state. Already shortened results
|
||||
are not scored again. It does not intercept manual native compaction.
|
||||
- Declares effective non-secret options through `release_policy_parameters()` so
|
||||
the host's assembly fingerprint changes when pruning policy changes. Neither
|
||||
the API key nor its environment variable name participates in that identity.
|
||||
|
||||
Optional deployment fields (all validated; unknown fields rejected):
|
||||
|
||||
| Field | Default | Meaning |
|
||||
| --- | --- | --- |
|
||||
| `api_key_env` | `TYPESAFE_API_KEY` | Environment variable name, never the key itself |
|
||||
| `trigger_tokens` | `60000` | Approximate history tokens; choose for your main model |
|
||||
| `preserve_recent_messages` | `6` | Protected suffix, minimum six |
|
||||
| `min_result_chars` | `4000` | Minimum eligible result length |
|
||||
| `min_calls_between_attempts` | `16` | Number of intervening calls to skip, including after failed attempts |
|
||||
| `max_candidates` | `8` | Per-request candidate limit, maximum 16 |
|
||||
| `keep_threshold` | `0.2` | Shorten only below this keep probability; maximum 0.5 |
|
||||
| `min_reduction_ratio` | `0.1` | Minimum estimated reduction of the whole history |
|
||||
| `timeout_seconds` | `8.0` | HTTP connect/read/write/pool timeout per phase |
|
||||
|
||||
## Prompt caches and cost
|
||||
|
||||
Shortening an old result changes the prompt prefix from that point onward and
|
||||
can invalidate the following cached suffix. The stable prefix before the edit
|
||||
can still be reused; subsequent calls can reuse the new prefix. Thresholds and
|
||||
spacing reduce how often history is rewritten, but **do not guarantee a net
|
||||
cost or latency saving**. Include Jev charges, the cache refill, cache discounts,
|
||||
future turns and any extra rereads when measuring. Approximate tokens removed
|
||||
are not money saved; providers' actual usage/cache counters are the evidence.
|
||||
|
||||
## Verify
|
||||
|
||||
From `backend/`:
|
||||
|
||||
```sh
|
||||
uv run pytest tests/test_jev_context_extension.py
|
||||
```
|
||||
|
||||
Coverage includes sync/async host isolation, checkpoint persistence, per-thread
|
||||
cooldown, message pairing, protected content, malformed decisions, failure
|
||||
fallback to real native summarization, cancellation and the plugin catalog.
|
||||
The **Jev Plugin Package** CI workflow separately builds and installs the wheel,
|
||||
then loads its declared entry point and registers its contributions through the
|
||||
real host. `scripts/verify_package.py --installed-dir PATH` runs that check against
|
||||
an isolated `uv pip install --no-deps --target PATH` installation; it does not
|
||||
substitute a source-tree import for the installed distribution.
|
||||
|
||||
An opt-in synthetic smoke test calls real Jev and a caller-selected
|
||||
OpenAI-compatible chat endpoint, without using real user transcripts:
|
||||
|
||||
```sh
|
||||
export TEST_CHAT_BASE_URL='http://localhost:8000'
|
||||
export TEST_CHAT_MODEL='your-test-model'
|
||||
uv run python ../examples/deerflow-extension-jev-context/scripts/verify_live.py
|
||||
```
|
||||
|
||||
This script deliberately sends no chat `Authorization` header. Use a test endpoint
|
||||
that supports unauthenticated access; only Jev receives the Jev bearer token.
|
||||
It compares the baseline/pruned prompt usage and checks retention of two recent
|
||||
facts. This small smoke test is not a general relevance or cost benchmark.
