onec-dev

onec-dev is a skill for Claude Code, Codex from Muredsa/1C-Enterprise-Agent-Toolkit. It costs 67 tokens per session (547 once invoked), scanned A, original, MIT.

A routing workflow for safe 1C:Enterprise development involving configuration metadata, an infobase, extensions, Designer batch mode, BSL code, or tests.

In plain words
What is it for?
It helps discover a compatible platform, create an isolated session, selectively inspect metadata, and coordinate extension development and testing.
Why use it?
It provides a controlled session and directs each task to the focused 1C workflow, helping protect the source infobase.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

onec-dev scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 36 lines — stays where its author put it; the contents beside it link to each section on GitHub.

1C Development Router

Operate through an isolated, auditable session. Preserve the source infobase and remove session-owned data after the task.

Start safely

  1. Read references/safety-contract.md.
  2. Locate scripts/onec.py. Check ONEC_DEV_CLI, a project checkout two levels above this skill, the executable onec-dev on PATH, then the user data locations documented in the safety contract.
  3. Run discover and select the newest compatible platform unless the user requested a specific version.
  4. Run session-create. For a file infobase, keep the default sandbox copy. Treat server, named, connection-string, and --no-sandbox sessions as live and require the user's explicit authorization.
  5. Keep the returned manifest path. Pass it to every subsequent command with --session.

Never put a password in a command, manifest, log, or chat. Pass only the name of an environment variable with --password-env. When an explicit 1C user is supplied, keep OS authentication disabled unless the user explicitly requests it.

Route the work

  • Invoke $onec-selective-export to inspect or export only the metadata required for the task.
  • Invoke $onec-extension-lifecycle to create, load, dump, edit, back up, roll back, or delete one named extension.
  • Invoke $onec-extension-validate to check BSL, validate applicability, update the extension database configuration, or verify the resulting .cfe.
  • Combine the focused skills in that order for implementation work: inspect dependencies, modify an extension, then validate it.

Do not change the main configuration for extension work. Do not use destructive Designer switches outside the allowlist in the safety contract.

Finish deterministically

  1. Report the meaningful result and any diagnostics from the JSON output and linked log files.
  2. Run session-cleanup --session <manifest> in a finally-style step whether the work succeeds or fails.
  3. If cleanup fails, stop and report the exact session path. Do not broaden the deletion target or retry with a stronger deletion command.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
