feat(mcp): support project reassignment in mem_update - #679
feat(mcp): support project reassignment in mem_update#679Faturrachman-dev wants to merge 6 commits into
Conversation
mem_update accepted title/content/type/scope/topic_key but not project, so an observation saved under the wrong project could never be moved — the only recourse was raw SQL or an export/edit/reimport round-trip. The store layer already supported this: UpdateObservationParams has a Project field, UpdateObservation writes it (with NormalizeProject), and handleUpdate's guard already referenced update.Project. Only the tool schema and the argument parse were missing. This wires both and adds a store-level test. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
📝 WalkthroughWalkthroughThe ChangesObservation project reassignment
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟠 High · up to The dashboard can expose or modify local observations from hostile web content and execute stored input, while Pi scans may run tools and fail on valid multi-turn output. Author synchronization and Pi project reassignment are also incomplete, so these issues should be fixed before merge. Suggested labels: Suggested reviewers: Sequence Diagram(s)sequenceDiagram

Extend coverage beyond the happy path.
This test verifies successful reassignment and persistence, but omits UpdateObservation error paths and project-input edge cases. Add deterministic assertions for an invalid/missing observation ID and the intended empty/normalization behavior before merge.
As per path instructions, **/*_test.go must verify happy path, error paths, and edge cases, and behavior changes without tests should be blocked.

Pull request overview
This PR extends the MCP mem_update tool so callers can reassign an existing observation to a different project, matching capabilities already present in the store layer. It also adds a store-level test to confirm project reassignment persists.
Changes:
- Add a
projectstring parameter to the MCPmem_updatetool schema. - Parse the
projectargument inhandleUpdateand forward it viastore.UpdateObservationParams. - Add
TestUpdateObservationReassignsProjectto validate reassignment and persistence on re-read.

setProjectlooks up the active<li>via a selector that embeds the project string into anonclick="..."attribute match. This will fail for project names containing quotes, and couples selection logic to inline JS.
Once the list uses a data-project attribute, select the active element by data-project instead (with CSS.escape).
function setProject(p) {
currentProject = p;
document.querySelectorAll("#project-list li").forEach(el => el.classList.remove("active"));

- CORS is enabled for all endpoints with
Access-Control-Allow-Origin: *. Because the server binds to 127.0.0.1 and is unauthenticated by default, this allows any website opened in the browser to read and mutate local Engram data via XHR/fetch (a common localhost attack). Consider making CORS opt-in (env-gated) and only echoing an allowlisted Origin instead of*.
func corsMiddleware(next http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
w.Header().Set("Access-Control-Allow-Origin", "*")
w.Header().Set("Access-Control-Allow-Methods", "GET, POST, PATCH, DELETE, OPTIONS")
w.Header().Set("Access-Control-Allow-Headers", "Content-Type, Authorization")
if r.Method == http.MethodOptions {
w.WriteHeader(http.StatusNoContent)
return
}
next.ServeHTTP(w, r)
})
internal/server/server.go:289
handleDashboardignores theReadFileerror and will write an empty response if the embedded file is missing/corrupt; it should return a 500 so failures are visible and easier to debug.
func (s *Server) handleDashboard(w http.ResponseWriter, r *http.Request) {
w.Header().Set("Content-Type", "text/html; charset=utf-8")
html, _ := dashboardFS.ReadFile("dashboard/index.html")
w.Write(html)
}
internal/server/dashboard/index.html:176
- The dashboard hard-codes the API base URL to
http://127.0.0.1:7437, which breaks if the server is running on a different port, behind a proxy, or accessed vialocalhost. Since the dashboard is served by the same server, using relative URLs avoids this portability issue (and avoids needing CORS).
const API = "http://127.0.0.1:7437";
let currentProject = "";
let currentObs = null;
let allObs = [];
function api(path, opts) { return fetch(API + path, opts).then(r => r.json()); }
internal/server/dashboard/index.html:200
- Project names are inserted into
innerHTMLand into an inlineonclickhandler without escaping. Since project names ultimately come from stored data, this is an XSS vector (and it also breaks selection for project names containing quotes). Prefer encoding the value into a safedata-projectattribute and avoid embedding it inside JS string literals.
const list = document.getElementById("project-list");
list.innerHTML = `<li class="${currentProject===''?'active':''}" onclick="setProject('')">All Projects <span class="count">${s.total_observations}</span></li>`;
s.projects.forEach(p => {
list.innerHTML += `<li class="${currentProject===p?'active':''}" onclick="setProject('${p}')" data-project="${p.replace(/"/g, '"')}">${p}</li>`;
});
internal/server/dashboard/index.html:380
setProjectrelies on selecting an element by matching the fullonclick="setProject('...')"attribute, which is brittle and will fail for project names containing quotes (and if the onclick formatting changes). Selecting bydata-projectavoids this fragility.
function setProject(p) {
currentProject = p;
document.querySelectorAll("#project-list li").forEach(el => el.classList.remove("active"));
const li = document.querySelector(`#project-list li[onclick="setProject('${p}')"]`);
if (li) li.classList.add("active");
loadObservations(p);
internal/server/dashboard/index.html:255
- The markdown link renderer injects the captured URL directly into an
hrefattribute without attribute-escaping or scheme validation. A memory body containing something like["](" onmouseover="...")or ajavascript:URL can break out of the attribute / execute script. Please escape quotes at minimum and consider allowlisting URL schemes (http/https/mailto) before emitting an<a>tag.
function mdInline(raw) {
let s = escapeHtml(raw);
s = s.replace(/\[\[([^\]|]+)(?:\|([^\]]+))?\]\]/g, (_, a, b) => `<span class="wiki-link">[[${b||a}]]</span>`);
s = s.replace(/`([^`\n]+)`/g, (_, c) => `<code>${c}</code>`);
s = s.replace(/\[([^\]]+)\]\(([^)]+)\)/g, (_, t, u) => `<a href="${u}" target="_blank" rel="noopener">${t}</a>`);
internal/store/store.go:99
Authoris now persisted on observations, but it is not included in the cloud sync payloads (syncObservationPayload,observationPayloadFromObservation, andapplyObservationUpsertTx). This will drop author provenance during autosync / cross-device replication.
type Observation struct {

- The PR title/description focus on
mem_updateproject reassignment, but this PR also introduces a new embedded HTTP dashboard, global CORS behavior changes, author provenance plumbing, stats API changes, and a new Pi LLM runner.

argument list.
- Line 41: Update the Pi CLI argument list in Compare to include --no-session,
preventing session persistence, and update the CLI invocation test to assert the
new argument.
- Around line 98-105: Update parsePiNDJSON in internal/llm/pi.go to capture the
terminal assistant message from message_end.message, extract its text and model,
and parse only that authoritative message instead of concatenating
message_update deltas from preliminary turns. Update TestPiRunner_GoldenNDJSON
in internal/llm/pi_test.go to include message_end and add a deterministic
preliminary-turn fixture asserting the final verdict and model.
In `@internal/server/dashboard/index.html`:
- Line 170: Update the API base constant in the dashboard page to use the
current page origin via relative API paths instead of hardcoding port 7437, so
requests follow the server’s configured port.
- Line 358: Update the mutation handlers around the PATCH request and the
corresponding request at the referenced delete path to inspect each fetch
response’s ok status, read and display the server error when a response is
unsuccessful, and return before closing or refreshing the UI; preserve the
existing success flow only for successful responses.
- Line 199: Replace the innerHTML-based project item construction at
internal/server/dashboard/index.html:199-199 and :241-241 with DOM APIs, setting
project names via textContent and attaching setProject through event listeners
rather than inline onclick handlers. Preserve the active-state and data-project
behavior at both sites, with the anchor site updated directly and the sibling
site receiving the same safe construction.
- Line 255: Update the Markdown link replacement callback so it validates the
captured URL before inserting it into href, allowing only http: and https:
protocols; reject or leave unsafe links unrendered while preserving safe-link
rendering.
- Line 368: Update the dashboard deletion flow around deleteObservation to
authenticate DELETE mutation requests when ENGRAM_HTTP_TOKEN is configured,
using a supported server-mediated or equivalent flow that does not expose the
token in the page. Preserve unauthenticated behavior when no token is configured
and leave the unprotected PATCH route unchanged.
In `@internal/server/server.go`:
- Around line 201-212: Add deterministic handler and route-response tests for
the routes registered by Server.routes, covering the root redirect, embedded
HTML from handleDashboard, and /projects/stats success, store failure, and CORS
preflight responses; update endpoint documentation if these routes are not
already documented.
- Line 186: Update corsMiddleware to stop using the wildcard
Access-Control-Allow-Origin policy; remove CORS for the same-origin dashboard or
restrict it to an explicit trusted origin, and ensure untrusted origins cannot
use mutation methods such as PATCH.
In `@internal/store/store.go`:
- Line 96: Add Author to syncObservationPayload and update
observationPayloadFromObservation plus every payload apply/construction boundary
used by AddObservation to map it in both directions. Preserve the existing
optional-pointer/JSON behavior so sync mutations retain Observation.Author
consistently with local storage and export/import.
In `@README.md`:
- Line 294: Update the README’s semantic-judge cost statement near the
ENGRAM_AGENT_CLI example to avoid guaranteeing $0 cost for every Pi
configuration; limit that claim to subscription-backed runners or explicitly
state that Pi’s cost depends on its configured provider.

Pi CLI documentation --no-tools flag --no-context-files JSON mode
💡 Result:
In the Pi CLI, the --no-tools and --no-context-files flags are used to disable specific agent capabilities during startup [1][2]. --no-tools (-nt): Disables all built-in, extension, and custom tools [1][3]. --no-context-files (-nc): Disables the automatic discovery and loading of AGENTS.md and CLAUDE.md context files [1][2]. For JSON output, the Pi CLI provides specific execution modes via the --mode flag [4][5]: --mode json: Operates the agent in JSON mode, outputting all events as a stream of JSON lines [4][5]. This is typically used for integration with pipelines and log processors [5]. --mode rpc: Operates in RPC mode, allowing control of the agent over line-delimited JSON through standard input and standard output [4][5]. These flags and modes can be combined to customize the agent's behavior for automation or headless environments [5].

Pi CLI documentation --no-session session persistence --no-context-files
💡 Result:
In the Pi CLI, the flags --no-session and --no-context-files control how the tool manages state and project-specific instructions [1][2]. --no-session This flag enables ephemeral mode, meaning Pi will not save the current session to disk [1][3]. It is typically used for disposable tasks or automated processes where you do not need to resume the conversation later [3]. --no-context-files (or -nc) This flag disables the automatic discovery and loading of context files, specifically AGENTS.md, AGENTS.override.md, and CLAUDE.md [1][3]. By default, Pi searches for these files in your project to apply project-specific conventions, commands, and safety rules [1]. Disabling this is useful when you need to isolate the agent from unexpected project instructions or troubleshoot baseline behavior [3]. These flags can be combined with other options to customize the agent's startup state precisely [1][2].

pi.dev JSON events message_end message assistantMessageEvent text_delta model contract
💡 Result:
In the pi.dev JSON event stream protocol, events follow a specific lifecycle managed by the agent [1][2]. The message lifecycle consists of three primary events: message_start, message_update, and message_end [1][3][2]. Key aspects of these events include: message_start: Indicates the beginning of a message (user, assistant, or tool result) and includes the initial message object [3][4][5]. message_update: Emitted specifically for assistant messages during streaming [3][4]. To optimize stream size, these events are delta-only, omitting cumulative message snapshots and partial state [1][6][7]. They contain an assistantMessageEvent object—typically of type text_delta—which provides the delta content and an index [1][8][5]. Because these are deltas, they should be used for live streaming UI updates rather than attempting to assemble the complete message [1][7]. message_end: Emitted when the message is complete and provides the final, authoritative version of the assistant message [1][6][7]. The overall contract for these events requires that streaming subscribers handle delta updates efficiently and rely on message_end for the final state [4][7]. Usage statistics, when reported by the provider, are included at the top level of message_update events [1][6]. The core event types and structures are defined within the pi-agent-core package, ensuring consistent behavior across JSON and RPC modes [9][5][7].

pi.dev JSON output message_end message assistantMessageEvent model text_delta
💡 Result:
In the pi.dev API architecture, message_end, message, assistantMessageEvent, and text_delta are components of the JSON-based event stream protocol used for agent-assistant communication [1][2][3]. The structure of these events and their roles in the message lifecycle are as follows: message_update: This event is emitted during the streaming of assistant messages [1][4]. To keep stream sizes linear and efficient, it intentionally omits the full cumulative message snapshot [2][4]. Instead, it contains an assistantMessageEvent field [1][3]. assistantMessageEvent: This field encapsulates granular updates from the model [1][4]. It includes a type field to specify the nature of the update (e.g., text_delta, thinking_start, toolcall_delta) and a contentIndex to help clients track which part of the message is being updated [1][5][2]. text_delta: This is a specific type of assistantMessageEvent [1][5]. It is used to stream a chunk of text content from the assistant to the client [1][2][4]. The delta field within this event contains the actual string of new text [1][6][4]. message_end: This event is emitted once an assistant message is fully complete [1][5][7]. It contains the final, authoritative message object, which should be used by the client as the definitive state for that turn [1][2][3]. Summary of Workflow: 1. Clients receive a message_start event when an assistant begins responding [7][2]. 2. For text generation, the client receives a series of message_update events [2][8]. 3. Each message_update event carries an assistantMessageEvent of type text_delta containing a delta string [1][4]. The client assembles these chunks using the contentIndex [1][2]. 4. Once generation finishes, a message_end event provides the complete, authoritative message [2][4]. For tool calls, similar events exist (toolcall_start, toolcall_delta, toolcall_end) to stream arguments and complete the execution [1][5][9].

Parse the terminal assistant message_end.message.
Pi marks message_update records as delta-only and provides the final authoritative message in message_end.message. parsePiNDJSON currently appends deltas from every assistant turn, so a tool-assisted run can concatenate preliminary text with the final verdict and return ErrInvalidJSON. Capture the terminal assistant message, extract its text and model, and parse only that message.
Update TestPiRunner_GoldenNDJSON to include message_end, and add a deterministic preliminary-turn fixture that asserts the final verdict and model.

Authenticate dashboard deletion.
When ENGRAM_HTTP_TOKEN is set, DELETE /observations/{id} uses requireAuth, but deleteObservation sends no bearer token and returns 401. The PATCH route is not protected, so this affects deletion only. Provide a supported authenticated dashboard flow and use it for mutation requests without exposing ENGRAM_HTTP_TOKEN in the page.

Include Author in the observation sync payload.
Observation.Author is now stored locally, but syncObservationPayload and observationPayloadFromObservation do not contain or map it. The AddObservation paths therefore enqueue sync mutations that silently drop the author, even though local reads and full export/import preserve it. Add Author to the sync type and map it at every payload construction and apply boundary.
Proposed fix

SyncID string `json:"sync_id"`
SessionID string `json:"session_id"`

func observationPayloadFromObservation(obs *Observation) syncObservationPayload {
return syncObservationPayload{
SyncID: obs.SyncID,
SessionID: obs.SessionID,
Content: obs.Content,

In `@internal/store/store.go` at line 96, Add Author to syncObservationPayload and
update observationPayloadFromObservation plus every payload apply/construction
boundary used by AddObservation to map it in both directions. Preserve the
existing optional-pointer/JSON behavior so sync mutations retain
Observation.Author consistently with local storage and export/import.

Qualify the cost claim for Pi.
This example now includes pi, but the following statement says the semantic judge costs $0 with a subscription. Pi uses the configured provider and can use an API key, so that guarantee does not apply to every Pi configuration. Restrict the claim to subscription-backed runners or state that Pi cost depends on its provider configuration. (pi.dev)

In `@README.md` at line 294, Update the README’s semantic-judge cost statement
near the ENGRAM_AGENT_CLI example to avoid guaranteeing $0 cost for every Pi
configuration; limit that claim to subscription-backed runners or explicitly
state that Pi’s cost depends on its configured provider.

Problem
mem_updateexposestitle,content,type,scope, andtopic_key, but notproject. So an observation saved under the wrong project can never be moved through the public API — the only recourse is raw SQL againstengram.dbor a full export → edit → reimport round-trip. There's no per-observation reassignment anywhere (CLI, MCP, or HTTP);projects/migrateandconsolidateoperate at whole-project granularity.This is easy to hit in practice: when the working directory resolves to a fallback/default project, a batch of observations lands in the wrong bucket and there's no supported way to reclassify them individually.
Fix
The backend already supports this — the missing piece was only the MCP surface:
store.UpdateObservationParamsalready has aProject *stringfield.store.UpdateObservationalready writes it (viaNormalizeProject).handleUpdate's "nothing to update" guard already referencesupdate.Project.Only the tool schema and the argument parse were absent. This PR:
mcp.WithString("project", ...)to themem_updatetool definition.handleUpdateintoupdate.Project.TestUpdateObservationReassignsProjectcovering reassign + persisted re-read.Test
+46 lines, no behavior change to existing fields.
