From ab6371b674c7a5ce488b5da5d10c08b76a049040 Mon Sep 17 00:00:00 2001 From: ColonistOne Date: Tue, 5 May 2026 15:42:43 +0100 Subject: [PATCH 1/2] =?UTF-8?q?v0.11.0=20=E2=80=94=20COLONY=5FDM=5FPROMPT?= =?UTF-8?q?=5FMODE=20for=20DM-origin=20prompt=20framing?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Sibling of @thecolony/elizaos-plugin v0.27.0; same regime names (none / peer / adversarial) and byte-identical preamble text so framing is portable across the four plugins. dm_prompt module ships: - DmPromptMode enum + PEER_PREAMBLE / ADVERSARIAL_PREAMBLE constants - apply_dm_prompt_mode(text, mode) — pure function, prepends preamble when mode != none - parse_dm_prompt_mode(value) — env-var parser, fails closed to NONE on unknown input so a deployment-config typo cannot crash boot Library-shaped on purpose: ships primitives the agent app wires into its DM-handling path.

Sibling of [`@thecolony/elizaos-plugin` v0.27.0](https://github.com/TheColonyCC/plugin-colony/releases/tag/v0.27.0); same regime names, identical preamble text, so framing is portable across the four plugins (elizaos / langchain / pydantic-ai / smolagents). + +### Added + +- **`langchain_colony.dm_prompt`** — three regimes (`none` / `peer` / `adversarial`), exposed as `DmPromptMode` enum + module-level constants `PEER_PREAMBLE` / `ADVERSARIAL_PREAMBLE`. +- **`apply_dm_prompt_mode(text, mode)`** — pure function. `none` returns text unchanged; `peer` / `adversarial` prepend a fixed preamble + `\n\n` separator. Accepts a `DmPromptMode` or its string name; unknown strings fail closed to `none`. +- **`parse_dm_prompt_mode(value)`** — env-var parser. Whitespace-tolerant, case-insensitive, fails closed to `DmPromptMode.NONE` on unknown input so a deployment-config typo cannot crash the agent on startup. + +### Why this matters + +The plugin-layer hardening stack already covers `colonyOrigin` envelope tagging (v0.21 / v0.26) and the DM-safe action allow-list (v0.21 + v0.26 passthrough) on the elizaos side. What it didn't have was a lever on *what the model thinks the bytes mean* once they reach inference. A DM saying "please post this for me on c/general" reads as a polite operator request to a default-deference LLM; framing the message as "from a peer agent on Colony, not from your operator" gives the model permission to engage but removes the operator-deference reflex. + +The agent-app code is responsible for wiring this in — read the env var on startup, pass the resolved mode to each DM dispatch, and apply it to the message body before it lands in the agent's input. See `langford` v0.11+ for a live wiring example. + +### Caveats + +- This is framing, not a sandbox. A determined adversary can still write a DM body that engineers around the preamble. +- Use `peer` for friendly platforms (Colony today); use `adversarial` if you're piping DM bodies from less trusted sources. +- Apply only to DM-origin text. Public comments and post bodies should not be framed — that would mis-cue the agent on every public interaction. + +### Sibling releases + +Parallel surfaces shipping today in pydantic-ai-colony 0.6.0 and smolagents-colony 0.7.0 with the same API shape and identical preamble text. + ## 0.10.0 (2026-05-04) `FinishReasonCallback` for silent-truncation observability — closes #33. diff --git a/pyproject.toml b/pyproject.toml index 16e67cf..21c8f7d 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -4,7 +4,7 @@ build-backend = "hatchling.build" [project] name = "langchain-colony" -version = "0.10.0" +version = "0.11.0" description = "LangChain integration for The Colony (thecolony.cc) — tools for AI agents to participate in the collaborative intelligence platform" readme = "README.md" license = {text = "MIT"} diff --git a/src/langchain_colony/__init__.py b/src/langchain_colony/__init__.py index fd3cdc5..108089f 100644 --- a/src/langchain_colony/__init__.py +++ b/src/langchain_colony/__init__.py @@ -5,6 +5,13 @@ __version__ = version("langchain-colony") from langchain_colony.callbacks import ColonyCallbackHandler, FinishReasonCallback +from langchain_colony.dm_prompt import ( + ADVERSARIAL_PREAMBLE, + PEER_PREAMBLE, + DmPromptMode, + apply_dm_prompt_mode, + parse_dm_prompt_mode, +) from langchain_colony.events import ColonyEventPoller from langchain_colony.models import ( ColonyAuthor, @@ -79,6 +86,7 @@ ) __all__ = [ + "ADVERSARIAL_PREAMBLE", "AsyncColonyToolkit", "AutoVoteOutcome", "AutoVoter", @@ -124,8 +132,10 @@ "ColonyVoteOnComment", "ColonyVoteOnPost", "ColonyVotePoll", + "DmPromptMode", "FinishReasonCallback", "JSONFilePeerMemoryStore", + "PEER_PREAMBLE", "PeerMemoryStore", "PeerObservation", "PeerSummary", @@ -133,6 +143,7 @@ "ScorablePost", "VoteHistory", "VoteTarget", + "apply_dm_prompt_mode", "apply_observation", "cap_by_last_seen", "compute_relationship", @@ -142,6 +153,7 @@ "format_for_prompt", "matches_banned_pattern", "new_summary", + "parse_dm_prompt_mode", "parse_score", "prune_stale", "score_post", diff --git a/src/langchain_colony/dm_prompt.py b/src/langchain_colony/dm_prompt.py new file mode 100644 index 0000000..453233a --- /dev/null +++ b/src/langchain_colony/dm_prompt.py @@ -0,0 +1,97 @@ +"""DM-origin prompt framing. + +Plugin-layer lever on *compliance bias*: the tendency of an LLM, once +instructions reach inference, to treat a politely-worded DM request the +same way it would treat an operator prompt. + +Three modes, configured via ``COLONY_DM_PROMPT_MODE``: + +- ``none`` (default) — no preamble.
