v0.9.5: a session owns a directory, and the store hands out uuids
A session's transcript lived beside its attachments, both named after an id
that was a timestamp. Two things fell out of that: on a workspace two
machines share, a timestamp is not an id (the same second on both is enough
to hand out the same name), and "delete this conversation" had to chase the
jsonl, the title and a directory in a shared attachments/ tree, guessing what
belonged to whom. A phone's app data has nobody to tidy it by hand.
Now one session is one directory:
<workspace>/.agent/sessions/
<uuid>/session.jsonl the transcript
<uuid>/title the window title, one line
<uuid>/attachments/ images and delivered files (img-…, art-…)
<uuid>/sub-1.jsonl an agent role's own transcript
CURRENT the id the next run opens
- src/agent_store.c: new_id() makes a uuid v4 (16 bytes from /dev/urandom,
clock+pid only as a fallback), dir_for_id/flat_for_id/nested_for_id/
shape_of_id decide which shape an id has, so every reader takes either.
An id is a directory name, so it is checked as one (no "/", no "..",
nothing starting with ".", not CURRENT or attachments). path_for_id() keeps
the shape a session already has and makes the directory for a new id, so
nothing had to change in the callers. store_list() lists the directories
that hold a transcript plus the flat files, newest first. delete() is one
rm_tree of the session's directory, plus the old shared attachments/<id>
and CURRENT when it pointed there.
- cst_agent_store_migrate() (--migrate-store, or plain cst-agent for a
session): moves a flat store in — <id>.jsonl to <id>/session.jsonl,
<id>.title in, the shared attachments/<id>/ to <id>/attachments/. rename
first, copy when the filesystem says no, and counts what it moved, so a
second run is a no-op that says "nothing to move". On the real workspace:
6 sessions moved, the shared directory gone, --list-sessions reads them
back unchanged, a second run moved 0.
- cst_agent_store_id_of_path(): the id of a session path. This is the bug the
whole change had been hiding: cst_agent_session_id() took the id from the
file name, and the new file name is session.jsonl -- every session would
have called itself "session" (the sidebar, CURRENT, undo, an agent role's
directory, and the metrics file, which now also goes through the helper).
- src/attach.c: a session that owns its directory keeps its payloads inside
it (<id>/attachments/); only the flat layout needs the shared directory and
the id stem. Attachments behave exactly as before otherwise.
- tests/test_store.c: uuid shape and uniqueness, a small buffer refused, a
new session's path and directory, write/list/info/title read back, the
payload landing in <id>/attachments/, delete taking the directory with it;
then an old-layout store: readable before the move, moved byte for byte,
its payload readable through the new path, listed once, a second migration
a no-op, deletion covering the migrated payload. Also in the Makefile and
CMakeLists test lists.
- app/src/ui/UiTest.cpp: the image directory check wanted "/attachments/",
which the new layout has no trailing slash for.
Desktop: build clean, make check 35/35, --uitest all green, --selftest and
cst-app-selftest OK, and --selftest opens a session of the migrated workspace.

v0.9.2: files the agent delivers come back as cards, and the saved key is used
A turn could write a report and say "here it is" -- and there was nothing to
open. The engine had no way to hand a finished file to the person, and the
front end had no way to show one. This release adds the whole path: a tool to
deliver, a store that keeps the copy, a card in the transcript, and open /
share through the platform. It also fixes two bugs the phone exposed while it
was being tried there.
deliver_file (engine)
- cst_attachment_t.for_user marks a copy that belongs to the person, not to
the model; cst_attach_import_artifact() stores any bytes up to
CST_ARTIFACT_MAX_BYTES (64 MB) with the mime taken from the name's
extension. Attachments are unchanged (content decides the type, 16 MB).
- It is a read-policy engine tool: path resolves inside the workspace, a
directory is refused, title (optional) is the display name.
- The wire is what keeps it out of the conversation: parts_add_attachments()
skips for_user entries without even a "not sent" note, and a turn that only
delivered a file no longer invents an empty user message. tests/test_artifacts.c
pins that down end to end, including a session-file round trip.
The card (Qt front end)
- filesText() replaced imagesText(): one line per file -- kind, stored name,
name, origin, mime, bytes, pixels -- decoded by ImageStrip.qml. A for_user
entry is a file card (extension badge, name, type and size, Open, Share);
a picture stays a thumbnail and opens on tap. Both shapes are read, so
sessions written by an older version still draw.
- AgentCore::openArtifact() / shareArtifact() accept a name only when one of
the session's own messages carries it, and hand the display name to the
platform layer for the status line.
- Android opens through the app's FileProvider (content:// + ACTION_VIEW,
resolveActivity() checked, read permission granted) and shares through the
share sheet; a desktop uses QDesktopServices / the clipboard.
CST_APP_NO_OPEN=1 makes --uitest run without opening anything.
Two bugs the device found
- The session writer had its own copy of the attachment JSON and forgot
`for_user`: the file survived the file, but came back as an attachment --
no card, and put back in front of the model. It now uses the one writer
(cst_attachments_to_json()), with the round trip covered by a test.
- engineToolImages() looked the card up with findTool(), which only finds a
card that is still running -- and the engine reports the result *before*
the files, so the card was already complete and the files were dropped.
A live turn therefore showed no card while a replay of the same session
did. It now matches on the call id.
- A tap that could not work said nothing: ImageStrip.qml's errorText was
never drawn. The card now carries the reason ("no app on the phone opens
report.md").
Also
- The saved provider key reaches the engine on every start: AgentCore::open()
was handed an empty key and the engine never resolves credentials itself
(only the CLI did), so every start asked for it again. It resolves the same
order main.c uses (saved key, provider environment, CST_API_KEY) and wipes
the copy it made; --selftest checks it against a scratch credentials file.
- Android: notification_send reads the Java exception text into its result,
and keeps failing on the NX789J -- the build() returns null and Qt clears
the exception before C++ can read it, so the call has to be wrapped in Java
next (docs/android.md says so).
- --uitest grew the delivered-file case (card, Open, Share, a forged name
refused), the live order of result-then-files, and the startup row count.

v0.9.0: the Qt front end as an Android APK, images in the transcript
Two strands land together: the window draws pictures now, and the whole front end builds, installs and runs on the phone with the engine linked in-process. Images (the "make a picture actually show up" part) - Engine, additively: cst_agent_hooks_t.on_tool_images(call, list, n, ud) fires when a call left attachments behind, and cst_agent_pending_rel() / cst_agent_pending_is_image() read that list without the app touching the store. tests/test_attach.c::test_agent_pending pins the three cases (an image, a stored name that passes cst_attach_rel_ok, out-of-range NULL). - App: image://cstattach/<stored name> (app/src/ui/SessionImages.cpp) serves only the current session's attachment directory, checked with cst_attach_rel_ok, decodes down to the requested sourceSize and never upscales, and holds a mutex because requestImage() runs on the render thread while the directory can change underneath it. AgentCore gained attachmentDir(), pendingImages(), the toolImages()/promptImages() signals and hookToolImages(); history() gives replayed rows their images too. - QML: ImageStrip.qml (a thumb strip, <=150 px tall, shaped by the picture, tooltip with name/size/origin, the file's name when it went missing), wired into MessageCard and ToolCard. Qt 6's ListModel cannot hold a list-valued role (append() reads back undefined, setProperty drops it), so a row carries one image per line as <stored>|<name>|<origin>|<w>x<h> and ImageStrip decodes that. Android (the engine is already in the APK; this is the front end) - app/src/main.cpp: on Android the workspace, config, tmp and HOME go under the app's own data directory before the engine opens anything, because QDir::currentPath() is "/" there and /tmp is not writable. - app/android/: the manifest (QtApplication/QtActivity, INTERNET and POST_NOTIFICATIONS, adjustResize, no storage permission -- the picker will be the system one), strings, a vector icon; minSdk 24 and targetSdk 35 come from app/CMakeLists.txt through QT_ANDROID_MIN/TARGET_SDK_VERSION. - app/src/platform/android/AndroidTools.cpp: the Android file behind PlatformInit(), owner "app:android" (notification, clipboard, share sheet, file picker are stubs for now, so the tool list does not lie about them). - app/tools/selftest.c decides its scratch workspace with os_temp_dir(), so the C smoke test runs on the device too. - scripts/build_apk_android.sh: sources to installed APK in one command (environment checks, qt-cmake configure, --target apk, adb install), and the host-side plumbing the NixOS + qt.io combination needs -- the NDK sysroot include dirs for Qt's FindGLESv2/FindEGL (they only look under <sysroot>/include), -L$PREFIX/lib on the shared/module link lines as well as the executables', the Android debug keystore created on first use with QT_ANDROID_SIGN_APK + QT_ANDROID_KEYSTORE_* (androiddeployqt copies the unsigned gradle output and signs it itself), and the #!/bin/bash shebang of the build-tools wrappers, which NixOS does not have. - scripts/gradle-android-init.gradle (installed into ~/.gradle/init.d/): the release lint task is switched off -- lintVitalAnalyzeRelease resolves its own tool jars straight from dl.google.com, bypassing every repository the build configures, and fails the build after all the real work is done. - Icons: app/icons/*.svg (Breeze's 24@3x files, the 19 names the window asks for) are compiled in as :/cst-icons and ThemeIcons.cpp falls back to them when the platform has no icon theme. On the phone the Qt theme lookup found nothing and the QML glyph fallback was an empty box in the phone's fonts. - docs/android.md: "The APK (Qt front end)" -- the SDK assembled without sdkmanager, the host Qt's missing libraries on NixOS, the Gradle mirrors, lint, signing -- and a Status that says what runs where. app/README.md gains the images and APK lines, and stops claiming Android platform tools that are still stubs. Verified: engine `make check` green; desktop `cst-app-selftest: OK` and --uitest all checks pass; phone (NX789J, Android 16, arm64-v8a) -- the APK installs, starts on the workspace under /data/user/0/xyz.whcself.cstagent/ files/, a turn reaches a configured provider over HTTPS from inside the ART process and renders the reply, rotation keeps the session and docks the sidebar, and the toolbar/card icons draw.

v0.8.15: custom providers and model parameters under Advanced options
The settings dialog could pick a preset, a model and a key and nothing else.
Two things were missing: a provider the presets do not know, and what the
model is asked to do while it answers. Both live under "Advanced options"
now, next to the entry they belong to.
Custom providers (engine)
- cst_models_user_set_provider() / cst_models_user_drop_provider() write the
engine's own user layer, <config>/cst-agent/models.json:
{"providers": {"myllm": {"api_base": ..., "key_env": ...,
"default_model": ..., "models": [...]}}}
and reload the registry, so the provider is at once in the provider list,
in the wire models[] and in the CLI's /provider -- the file a hand-written
override would go into is the same one, so the GUI and an editor agree.
The name is checked (1-31 of letters, digits, '.', '_', '-'), a preset's
name overrides that preset (a self-hosted endpoint, a proxy), everything
else in the file (model rules) is kept, and a file that is not a JSON
object is never overwritten. Dropping only removes the user's own entry.
- AgentCore::providers() gained "custom" (source == "user"), and
addProvider() / removeProvider() drive the two calls above.
Model parameters (engine + wire)
- cst_agent_config_t and cst_llm_request_t carry temperature, top_p and
max_tokens. 0 means the field is not sent at all -- an absent field is the
provider's own default, which "temperature": 0 is not (deterministic
decoding is a real choice), so cst_llm_build_body() only adds what was set.
tests/test_llm_body.c:test_gen_params pins both halves.
- settings.json keeps them per provider ("params": {...}) via
cst_settings_remember_params(); cst_settings_remember() carries them along
with the provider choice, and cst_agent_create() reads them, so a CLI or
TUI run sends what the window was set to. An all-zero config (the CLI)
leaves what the GUI saved alone.
- AgentCore::genParams() / setGenParams(), and useProvider() applies both the
remembered parameters of the provider it lands on and a base URL that was
edited in the dialog.
The dialog
- Rewritten around one scrolling body with a fixed footer: a long model list
used to push the key field and the buttons out of the dialog. The model
chips are filtered (a filter field appears past twelve) and capped at 40
with "... +N more", which is what a router with hundreds of models needs.
- "Advanced options" folds out the provider entry (name, base URL, key
variable, default model, models; Save provider / Remove from models.json)
and the model parameters (temperature, top-p, max tokens; empty = not
sent). The fields follow the picked provider and are what gets saved, so a
hand-typed edit is never lost to a stale property.
Verified: --uitest 67/67 (15 new checks: parameters round-trip through the
engine, a provider added through the form and removed again, a bad name
refused, a preset not removable), --selftest, ctest cst-app-selftest, and
make check with the new body test.

v0.8.6: general mode, clipboard text, PDF text extraction
Working mode: --mode coding|general (CST_MODE, settings.json, /mode, WebUI run settings). general swaps the default framing for a general assistant one -- workflow, safety notes, tool wording (run_shell, the subagents) -- and /status shows it; minimal (the paper profile) stays byte-frozen. The prompt state carries the mode so a switch leaves a system note in history. Clipboard: clipboard_read / clipboard_write tools (16 MiB cap read, default 64 KiB window; writing is a WRITE permission with a preview) on pbcopy / wl-copy / xclip / pbpaste / wl-paste / xclip and the Win32 clipboard. In the TUI, /attach paste falls back to clipboard text when there is no image on it. PDF: a dependency-free text extractor (src/pdf_text.c): inflate, Flate/ASCIIHex/ASCII85, PNG/TIFF predictors, layout-independent object scan, object streams, page tree walk with inherited resources, content lexer (Tj/TJ/'/" and the Td/TD/T*/Tm spacing heuristics), per-font ToUnicode CMaps and inline images skipped. Encrypted files and pages with no text layer are refused with the reason. Attachments: /attach (a path or files dropped on the terminal) now take images, PDFs and text. A PDF is stored as its text layer with the mime still saying application/pdf and its page count; anything else has to be UTF-8 text. Documents travel inline as text parts, so CST_NO_IMAGES and text-only models no longer drop them, while images keep their old path. Tests: test_pdf_text (plain, bare and zlib-framed Flate, inline image, CID + ToUnicode, object stream, error paths), documents in test_attach, inlined documents in test_llm_body, mode in test_config. |

v0.8.4: WebUI sessions, diff, settings, slash commands and extensions
Sessions: rename, delete and search; /api/retry regenerates the last answer, editing a prompt resends from there; /api/export downloads the transcript as Markdown (cst_session_export_md). Session messages carry note/tool_result markers, so a reload rebuilds the tool steps with their arguments, output and exit status; subagent progress is shown. Diff and settings: /api/diff shows the real diff; /api/settings covers protocol, max_steps, tool switches and confirm; /api/permissions edits the rules; sandbox status is reported. Session rename no longer reads past a short title. Commands: slash commands with completion in the composer (/model, /provider, /new, /retry, /undo, /compact, /export, /diff, /init, /skill and more), a Ctrl+P palette, Shift+Tab cycles the approval mode, F1 or ? shows the keys. "Thinking expanded" is saved in the settings (show_thinking), "expand all tool output" in the browser. Extensions: GET /api/extensions lists MCP servers, plugins, skills, agent roles and subagent runs; POST /api/extensions/reload and /api/extensions/trust; a workspace switch reloads them. /api/init and /api/skill run on the server (cst_init_prompt shared with the TUI). Errors, statuses and [cst] notes are shown in Chinese with a readable reason instead of rc=; a failed turn's error survives the reload. Tests: scripts/e2e_webui_sessions.py, e2e_webui_workspace.py and e2e_webui_ext.py, run from e2e_webui.sh. |

v0.8.0: WebUI redesign, /web, workspace switch, 75% budget, no shell timeout
The front end is rebuilt on the design tokens the desktop app ships (surfaces, color-mix borders, alpha hovers, accent): a 30-icon inline SVG sprite, dark and light themes, layout switches as deep links (?side=0, ?panel=0, ?theme=light) resolved before the first paint. The empty page is one line and leaves with the first turn; the right rail keeps three cards - todo, file changes (+N -M) and context (tokens, prompt cache hit rate). Both rails animate in and out, and a collapsed rail widens its grid track to 0 instead of being removed, so the transcript never slides into a zero-width column. - src/webui.c: POST /api/workspace - re-root the agent at another directory (permission rules, metrics, AGENTS.md follow) and start a session there, as sessions live per directory; state also reports cached/cache_miss tokens - src/agent_loop.c: cst_agent_set_workspace(), rebuilt prompt and re-measured budget; the auto-compact threshold is 75% of the window (was 60%) - src/tui.c: /web forks a WebUI next to the TUI - separate process and a new session, because cst_webui_run() blocks and two writers corrupt one session - src/os_compat.c, src/os_win.c: run_shell runs without a time limit unless CST_SHELL_TIMEOUT asks for one, so builds and long clones finish - src/main.c, include/cst_webui.h: one CST_WEBUI_DEFAULT_PORT for --help, the docs and /web; Termux opens the browser through termux-open-url - README.md, docs/webui.md, docs/env_openai.md: /web, /api/workspace, the new state fields, the 75% threshold and the layout deep links tests/e2e_webui.sh green (permission round-trip, token paths, --web-dev); make check green. |

v0.7.0: image input, model registry, prefix-cache savings
Images - vision gate: text-only models get a note instead of image parts and no view_image tool; unknown models retry once without images on HTTP 400 - paste: Ctrl+V and /attach paste read the clipboard (wl-paste, xclip, pngpaste/osascript, Win32 PNG or CF_DIB converted to PNG); pasting image file paths attaches them - MCP image content is stored in the session and sent with the tool result - attach: rel path validation, base64 decode, /retry keeps images Model registry - built-in src/models_builtin.json embedded at build time, merged with <config>/models.json and cached GET /models metadata (context, vision, pricing); most specific rule wins per field - /model labels, /status source, --list-models [provider] Cache and cost - stable request prefix (frozen tools, notes as messages), DeepSeek prefix completion, OpenAI/Anthropic cache hints, /cost and hit rate in the status |

Usability pass: tool registry, TUI polish, saved keys and settings
Tools - Table-driven tool registry with permission classes and default/minimal profiles; new tools: edit_file, list_dir, glob, grep, delete_file, move_file, todo_write, web_fetch, ask_user (plus read_file paging). - Built-in Myers diff; write tools return unified diffs. - Persistent permission rules (.agent/permissions.json), per-turn undo snapshots (.agent/undo), AGENTS.md project notes, auto-compact at 80% of the model context, cancellable run_shell with process-group kill. TUI - Table-driven slash commands: /provider /key /effort /status /tools /permissions /yolo /undo /retry /diff /export /copy /rename /delete /init /max-steps /todo, with / and @ completion. - Permission modal with diff and prefix rules, ask_user modal, todo panel, header with model/effort/context, bracketed paste, line editing, wide-char cursor, NO_COLOR and ASCII fallback; Esc never quits. Startup and configuration - API keys are entered in the TUI (hidden) and saved per provider in <config>/credentials (0600); env variables are only a fallback. - Last provider, per-provider model and reasoning effort are remembered in <config>/settings.json; --effort/-e and /effort send reasoning_effort (low|medium|high|max) to models that accept it. - DeepSeek preset uses deepseek-flash / deepseek-v4-pro. - Session flags --new/--continue/--resume/--list-sessions, --yolo, --confirm. Compatibility and tests - ncurses detection, macOS/Homebrew support, make install, XDG config dir, POSIX cleanups; Gitea CI (gcc/clang/asan/musl/macOS). - Unit tests for diff, fs tools, registry, undo/perms and config; e2e fixtures multi_file_refactor and ask_or_todo; vendored cJSON. |
