LLM-driven pipeline that forges, validates, and promotes TextFSM templates from network CLI output

ParseForge

LLM-driven pipeline that forges, cross-validates, and promotes TextFSM templates from network device CLI output.

Full design plan: SPEC.md.

Status

Early beta. The full pipeline is implemented and tested end to end — naming, sampling, generation, self-validation, integration (output-schema group/variant clustering), promotion (auto and human-reviewed), and drift monitoring — and wired into the CLI below. A few things are intentionally not there yet:

• USER_REVIEWED promotion has a library entry point but no CLI command (promotion.promote_user_reviewed() works today; there's no parseforge promotion --mode user-reviewed yet). Deferred until real human-reviewed cases exist to show what a CLI/config shape for a list of case/suffix/gate requests should actually look like, rather than guessing ahead of need.
• Batch sampling mode (collect several samples per command before generating, SPEC.md §4) is designed but not built — the simpler per-command loop mode is the only one implemented.
• One sampling connector (Netmiko/SSH). The CLI's --connector registry is built to hold more without a redesign, but nothing else is wired in yet.

Installation

pip install parseforge[anthropic]

pip install parseforge alone installs no AI-provider SDK at all — every command that's pure local processing (canonical/readable/recognizers, integration, promotion) works with nothing further. Anything that calls an LLM (name, check --provider, run, generate-template, trial) needs the extra for whichever provider it uses: anthropic or deepseek. --provider defaults to anthropic wherever it isn't required, so that's the one most setups need. pip install parseforge[sampling] adds Netmiko for live device sampling; combine extras as needed, e.g. pip install parseforge[anthropic,deepseek,sampling].

Development

pip install -e ".[dev,sampling]"
pytest

dev already includes both anthropic and openai (tests exercise both providers, never silently skip) — add ,anthropic/,deepseek explicitly only if installing outside of dev.

Linting/formatting/type-checking/docs run through tox instead of extras — see tox.ini (tox -e lint/format/typecheck/docs), each installing its own tools in an isolated env. Cutting a release needs pip install -e ".[release]" (bump2version, build) — see scripts/release.ps1.

CLI

Three kinds of commands: single lookups (name, check), one-shot inspection with no persistence (generate-template, canonical/readable/recognizers), and the config-driven trial → integration → promotion workflow that runs the full pipeline end to end (see Quickstart: end to end below).

Naming — resolve a raw CLI command to its canonical cli-name (cached after the first call, per SPEC §2):

parseforge name --vendor cisco --family catalyst9200 --os ios-xe --version 17.9.1 \
  show interface GE1.1 status

Still needs an LLM provider on a cache miss — --provider defaults to anthropic, and --api-key falls back to that provider's own env var (ANTHROPIC_API_KEY/ DEEPSEEK_API_KEY). A cache hit (a command already seen before) never touches the LLM, so no key is needed at all in that case.

check — validate a connector or provider before spending time/tokens on a real run. With neither --env nor explicit connection flags, prints what a connector needs instead of attempting a connection:

parseforge check --connector netmiko --env cisco
parseforge check --provider anthropic

--env=<name> reads <NAME>_SANDBOX_HOST/USERNAME/PASSWORD/DEVICE_TYPE from the environment (the same convention the test suite uses for CISCO_SANDBOX_*).

generate-template — one-shot template generation, no trial persisted under trials/:

parseforge generate-template --sample-file sample.txt \
  --provider anthropic --api-key $ANTHROPIC_API_KEY --model claude-haiku-4-5-20251001

Also accepts --connector/--cmdline (live sample) or --config <file> in place of --sample-file; add --out <dir> to also write template.textfsm/readable-dsl.txt/ recognizers.txt to disk. parseforge init-generate-template-config [--out <file>] writes a placeholder for that --config file, ready to fill in.

canonical / readable / recognizers — inspect an existing template file. No LLM call; --sample is required to build the example records textfsm-ai's DSL compiler needs:

parseforge canonical template.textfsm --sample sample.txt
parseforge readable template.textfsm --sample sample.txt
parseforge recognizers template.textfsm --sample sample.txt

run — a single full trial (sample -> generate -> self-validate), SPEC §5 steps 1-7:

parseforge run --vendor cisco --family catalyst9200 --os ios-xe --version 17.9.1 \
  --host 10.0.0.1 --username admin --device-type cisco_ios \
  --provider anthropic --api-key $ANTHROPIC_API_KEY \
  --model claude-haiku-4-5-20251001 \
  show clock

--provider/--api-key/--model are for generation. Naming has its own separate --naming-provider/--naming-api-key/--naming-model, defaulting independently (--naming-provider defaults to anthropic; the other two fall back to that provider's own env var/default model) — set them explicitly if naming needs a different provider than generation.

init-trial-config — write a placeholder trial.yaml to fill in, instead of writing one by hand:

parseforge init-trial-config --out trial.yaml

trial — every command in a YAML config file, optionally in parallel:

parseforge trial --config trial.yaml

vendor: cisco
family: catalyst9200
os: ios-xe
version: 17.9.1
connector: netmiko
host: 10.0.0.1
username: admin
password: secret
device_type: cisco_ios
provider: anthropic
api_key: sk-...
model: claude-haiku-4-5-20251001
commands:
  - show clock
  - show version
user: alice
workers: 1

provider/api_key/model are one shared LLM source used for both naming and generation. Use the run command's separate --naming-*/--generation-* flags instead if a trial actually needs two different providers.

integration — rebuild integration/ for every case under trials/ (SPEC §5 step 8):

parseforge integration

promotion — auto-promote every group that clears its gate (SPEC §5 step 9; AUTO_PROMOTED mode only — USER_REVIEWED has no CLI surface yet):

parseforge promotion --user alice --threshold 1.0 --min-samples 1

trial, integration, and promotion all default to paths.DEFAULT_STORE_ROOT (~/.parseforge/tests); pass --path <dir> to point at a different store root.

Quickstart: end to end

Run trial once per device/command batch (repeat as more devices or commands come in — each run only adds new evidence, it never discards prior trials), then integration and promotion any time you want the current evidence reflected in authoritative/:

parseforge trial --config trial.yaml
parseforge integration
parseforge promotion --user alice

integration rebuilds integration/reference-summary.json from every trial currently on disk, and promotion always refreshes integration itself before evaluating any gate — so running promotion alone after a trial run is enough to pick up new evidence; a separate integration run is only useful if you want to inspect reference-summary.json without also promoting.
