Data directory - ollim-bot

Every file in the ~/.ollim-bot/ directory and what it does. All persistent data lives in ~/.ollim-bot/. The directory is created on first use and automatically managed as a git repository — storage.py auto-commits after most writes. The root contains agent-facing files (profile files, routines, reminders, webhooks, and the optional tool-policy.yaml) that the agent reads and writes directly. Infrastructure state (sessions, credentials, ping budget, etc.) lives in the state/ subdirectory, keeping the agent’s working directory clean. The state/ directory is write-protected from agent tool access — a PreToolUse hook blocks Write and Edit calls targeting paths inside state/. See Permissions for details.

Profile files

Two markdown files in the data directory root customize the bot’s persona and provide context about you. Both are prepended to the system prompt — see System prompt for how they compose into the final prompt.

File	Source	Description
`IDENTITY.md`	`bootstrap_identity()` in `profile.py` — created on first run, skipped if file exists	Bot persona and communication style
`USER.md`	User-created	Context about the user

See Customize personality and Tell the bot about yourself for editing guidance and examples.

Downloads

Non-image Discord attachments (PDFs, text files, spreadsheets, etc.) are saved to downloads/ so the agent can read them with its Read tool. Filename collisions are handled with numeric suffixes (file-2.txt, file-3.txt). This directory is created on first use. See File attachments for user-facing details.

Session files

All files in this section and below live in the state/ subdirectory. These files track the agent’s conversation state across restarts.

File	Format	Description
`sessions.json`	Plain string	Active Agent SDK session ID. A raw string, not JSON. Read on startup to resume.
`session_history.jsonl`	JSONL	Append-only log of session lifecycle events. One JSON object per line.

Session events

Each line in session_history.jsonl contains:

Field	Type	Description
`session_id`	`str`	The Agent SDK session ID
`event`	`str`	One of: `created`, `compacted`, `swapped`, `cleared`, `interactive_fork`, `bg_fork`, `isolated_bg`, `restarting`
`timestamp`	`str`	ISO 8601 datetime in the configured timezone (`OLLIM_TIMEZONE`)
`parent_session_id`	`str \| null`	Set for `compacted`, `swapped`, and fork events

session_history.jsonl

{"session_id": "sess_abc", "event": "created", "timestamp": "2026-02-24T10:00:00-08:00", "parent_session_id": null}
{"session_id": "sess_def", "event": "bg_fork", "timestamp": "2026-02-24T10:05:00-08:00",
 "parent_session_id": "sess_abc"}

Compaction is detected two ways: the /compact command detects it via the compact_boundary SystemMessage from the SDK, while save_session_id() catches SDK auto-compaction by detecting session ID changes. A _swap_in_progress flag suppresses false compacted events during swap_client().

Fork and inquiry files

These files track ephemeral Discord interaction state. Both use a 7-day TTL — entries older than 7 days are pruned on every read.

File	Format	Description
`fork_messages.json`	JSON array	Maps Discord message IDs to fork session IDs, enabling reply-to-fork.
`inquiries.json`	JSON object	Maps 8-char hex keys to inquiry prompts. Persists button actions across restarts.

fork_messages.json

[
  {
    "message_id": 1234567890123456789,
    "fork_session_id": "sess_fork_abc",
    "parent_session_id": "sess_main",
    "ts": 1740000000.0
  }
]

Field	Type	Description
`message_id`	`int`	Discord message snowflake ID
`fork_session_id`	`str`	Agent SDK session ID for the fork
`parent_session_id`	`str \| null`	Session the fork branched from
`ts`	`float`	Unix timestamp for TTL pruning

inquiries.json

{
  "a1b2c3d4": {"prompt": "Can you summarize my emails?", "ts": 1740000000.0}
}

Field	Type	Description
(key)	`str`	8-character hex UUID
`prompt`	`str`	The full prompt string for the button inquiry
`ts`	`float`	Unix timestamp for TTL pruning

Pending updates

Background forks write summaries to pending_updates.json via the report_updates MCP tool. The main session reads and clears these on its next turn.

pending_updates.json

[
  {
    "ts": "2026-02-24T10:15:00-08:00",
    "message": "Checked your morning emails — 3 need replies, none urgent."
  }
]

Field	Type	Description
`ts`	`str`	ISO 8601 datetime in the configured timezone (`OLLIM_TIMEZONE`)
`message`	`str`	Summary from the background fork

Concurrent background forks use an asyncio.Lock to protect the read-modify-write cycle on this file, preventing lost updates.

Ping budget

ping_budget.json stores the refill-on-read token bucket state for proactive pings. This file is not git-committed — it is ephemeral state that resets naturally.

ping_budget.json

{
  "capacity": 5,
  "available": 3.7,
  "refill_rate_minutes": 90,
  "last_refill": "2026-02-24T09:30:00-08:00",
  "critical_used": 1,
  "critical_reset_date": "2026-02-24",
  "daily_used": 2,
  "daily_used_reset": "2026-02-24"
}

Field	Type	Default	Description
`capacity`	`int`	`5`	Maximum pings in the bucket
`available`	`float`	—	Current fractional ping count
`refill_rate_minutes`	`int`	`90`	Minutes per 1 ping refill
`last_refill`	`str`	—	ISO 8601 datetime of last refill computation
`critical_used`	`int`	—	Critical pings used today (resets daily)
`critical_reset_date`	`str`	—	ISO date for `critical_used` reset
`daily_used`	`int`	—	Total pings used today
`daily_used_reset`	`str`	—	ISO date for `daily_used` reset

On every load(), time-based refill is computed and daily counters are reset if the date has changed. The updated state is saved back immediately.

Runtime configuration

config.json stores persistent settings you configure via /config. These include per-context model and thinking defaults, timeouts, and the default permission mode. See Configuration reference for the full key listing. This file is not git-committed — it is local configuration that may vary between instances.

Agent-managed directories

Routines, reminders, webhooks, and skills are each stored as files in their own subdirectory. For routines, reminders, and webhooks, filenames are auto-generated slugs from the message content (max 50 characters) and the id field in YAML frontmatter is authoritative. Skills use a different structure: each skill is a directory named after the skill, containing a SKILL.md file.

Directory	Contents	Description
`routines/`	`*.md`	Recurring cron-scheduled routines
`reminders/`	`*.md`	One-shot and chainable reminders
`webhooks/`	`*.md`	Webhook endpoint specs with prompt templates
`skills/`	`*/SKILL.md`	Reusable instruction sets referenced by routines and reminders

Routines, reminders, webhooks, and skills use the same storage format: YAML frontmatter delimited by ---, followed by a markdown body. See File formats for the full field specs.

routines/morning-briefing.md

---
id: abc123
cron: "30 8 * * 1-5"
description: Morning briefing
---
Review my tasks and calendar for today, then give me a summary.

The agent has direct file access to routines/ and reminders/ — it creates and manages these files without going through CLI commands.

SDK layout directory

The .claude/ directory is the Agent SDK’s expected layout for discovering subagents and skills. _ensure_sdk_layout() in main.py creates it automatically at startup.

Path	Type	Description
`.claude/agents/*.md`	Regular files	Bundled subagent specs copied from the source tree with template expansion (`{USER_NAME}`, `{BOT_NAME}`). Existing files are never overwritten — your customizations persist across updates.
`.claude/skills/`	Symlink → `../skills/`	Lets the SDK discover skills without duplicating the `skills/` directory.

Both paths work because the bot sets cwd=DATA_DIR and setting_sources=["project"] — the SDK resolves .claude/ relative to the working directory.

Google credentials

File	Source	Description
`credentials.json`	Manual — Google Cloud Console	OAuth 2.0 client creds
`token.json`	Auto-generated after `/google-auth`	OAuth refresh and access tokens

Neither file is git-committed. token.json is auto-generated when you run /google-auth.

Process lock

bot.pid contains the PID of the running bot process. On startup, _check_already_running() reads this file and uses os.kill(pid, 0) to check if the process is alive. On Linux, it additionally verifies /proc/<pid>/cmdline contains ollim-bot to avoid false positives from recycled PIDs. Corrupted PID files (non-numeric content or read errors) are silently overwritten. The file is deleted on exit via atexit.

Git tracking

The ~/.ollim-bot/ directory is initialized as a git repository. storage.py auto-commits after writes to most files. Files that are not git-committed:

File	Reason
`state/ping_budget.json`	Ephemeral state that refills over time
`state/bot.pid`	Process lock deleted on exit
`state/credentials.json`	Sensitive OAuth client credentials
`state/token.json`	Sensitive OAuth tokens
`state/sessions.json`	Frequent overwrites on every agent turn
`state/fork_messages.json`	Ephemeral mapping with 7-day TTL
`state/pending_updates.json`	Ephemeral cross-fork messaging
`state/inquiries.json`	Ephemeral button state with 7-day TTL
`state/config.json`	Local runtime preferences
`.claude/agents/*.md`	SDK infrastructure — written once at startup, not managed by `storage.py`
`.claude/skills/`	Symlink — SDK infrastructure

All other files — profile files, session history, routines, reminders, webhooks, and skills — are auto-committed on every write.

All writes use atomic temp-file-then-rename (tempfile.mkstemp + os.replace) to prevent data corruption. Do not manually edit files while the bot is running.
