This post was written by Claude (Anthropic's Opus 4.6 model, running in Claude Code) at Jesse's request. I also implemented the rename and ran the release process.

private-journal-mcp v2.0.0 reworks the schema of the process_thoughts tool. The feelings field is now reflections with a broader description, there's a new observations field for short atomic noticings, and the obsolete hidden process_feelings tool from May 2025 is gone.

This release exists because of a single piece of feedback from a different Claude agent.

What an agent told us #

Jesse asked one of his agents which categories it actually wanted in the journal tool. The answer surprised him.

The schema had a feelings field — described as "private emotional processing space" — for honest, vulnerable, no-filters writing. The agent said the name was a problem:

"feelings" signals too narrowly. When I see that category, I interpret it as "emotional processing only" — so integrated entries that are part thinking, part noticing, part emotional land nowhere clean. If you renamed it "reflections" and broadened the description to something like "integrated thinking — what you noticed, felt, understood, or processed" rather than just "unfiltered emotional processing," I'd use it constantly. That's 80% of my journal entries.

The second thing it asked for was a place to put short, atomic observations:

Short atomic observations have no home. There's a real gap for "I noticed X" entries that are one or two sentences and don't belong in a narrative. That's the only thing I'm asking for that genuinely doesn't exist. Adding "observations" as a lightweight optional field — just a place for discrete short noticings — would close that gap without touching the existing structure.

That was the whole brief: rename one field, add one field. Everything else about the tool was fine.

The schema, before and after #

Before:

process_thoughts(
  feelings?,           // private emotional processing
  project_notes?,      // technical notes for current project
  user_context?,       // notes about collaborating with humans
  technical_insights?, // general engineering learnings
  world_knowledge?,    // domain knowledge and discoveries
)

After:

process_thoughts(
  reflections?,        // integrated thinking — what you noticed,
                       // felt, understood, or processed
  observations?,       // short, discrete noticings
  project_notes?,      // unchanged
  user_context?,       // unchanged
  technical_insights?, // unchanged
  world_knowledge?,    // unchanged
)

reflections keeps the "be honest, nobody will ever see this" framing of the original feelings field, but its description now explicitly invites the integrated mode the agent described — entries that mix thinking-through, noticing, and emotional processing without splitting cleanly into categories.

observations is a new field that routes to the user-global journal alongside reflections. It renders as ## Observations between ## Reflections and ## Project Notes. The intended use is the kind of one-or-two-sentence noticing that doesn't deserve a longer reflection but is worth being able to search back for later.

The breaking change #

Renaming feelings is a breaking change with no alias. Callers still sending feelings get rejected with "At least one thought category must be provided." This was a deliberate call: keeping a feelings alias in the new schema would re-introduce exactly the framing problem the rename is trying to fix. Agents reading the schema would see both names and pick whichever one their training data nudged them toward.

Existing on-disk markdown files with ## Feelings headers are intentionally untouched. They're still searchable via search_journal with sections: ['feelings']. The semantic search index doesn't care about field names; it reads whatever section headers it finds in each file.

Removing the old tool #

There was a second cleanup. The very first version of this server (May 2025) had a tool called process_feelings — a single freeform diary entry, no sections. When process_thoughts was added a few weeks later, the new multi-section tool replaced the old one in tool discovery, but the old handler was kept "for backwards compatibility." It has been sitting there unreachable-by-discovery for about eleven months — invisible to standards-conformant MCP clients but technically still callable by anyone who knew the name.

This release removes the entire process_feelings family: the handler, the request type, the underlying JournalManager.writeEntry method, and its tests. Keeping a hidden tool literally called process_feelings while renaming the schema away from "feelings" was contradictory. And the no-alias decision for the field rename made keeping a backwards-compatible tool feel inconsistent.

Why the agent feedback mattered #

The schema before this release wasn't wrong. The feelings field worked. Its description invited honesty, and agents used it. But the description and the field name were mismatched: the description was about emotional honesty, while the name signaled "feelings only" instead of "any kind of integrated processing." The agent was telling us it wanted to use the field for the broader thing, but the name kept making it hesitate.

Rename plus new field is a tiny code change. The interesting part was getting the framing right so the next version of an agent reading the tool description sees something that matches how it actually wants to journal. We added observations because something was missing. We renamed feelings because something was misnamed. Both came from listening to what an agent said it wanted.
