# idx-cli — System Design & Project Blueprint
> CLI tool for Indonesian stock market (IDX) analysis. Built for humans and AI agents.
## References
These CLIs informed the design patterns used in this spec:
- **[Google Workspace CLI (`gws`)](https://github.com/googleworkspace/cli)** — Dynamic command surface from API discovery, strict auth precedence (flag > env > config), encrypted credential store, MCP mode, schema introspection commands. Great model for agent discoverability.
- **[Polymarket CLI](https://github.com/Polymarket/polymarket-cli)** — Clean domain-based command hierarchy (`markets`, `events`, `wallet`), `--output table|json` global flag, config file + env overrides + flags precedence, interactive shell mode. Direct template for our command tree and output modes.
- **[Obsidian CLI](https://help.obsidian.md/cli)** — `group:subcommand` naming, multi-format output (`json|csv|tsv|md`), TUI/shell mode + one-shot mode, clear docs on execution context and caching behavior. Good reference for help ergonomics.
---
## Goals
1. **Fast, single-binary CLI** — Rust + clap, zero runtime deps
2. **Human-first, agent-friendly** — readable tables by default, `--json` for machines
3. **Self-documenting** — agents discover capabilities via `--help` alone
4. **Composable** — pipe, script, batch — standard Unix CLI philosophy
5. **Offline-safe** — graceful degradation, local caching, no crashes on network failure
---
## Data Sources
### Primary: Yahoo Finance (unofficial HTTP API)
- Real-time quotes, fundamentals, historical OHLC
- No API key required
- Endpoint: `https://query1.finance.yahoo.com/v8/finance/chart/{SYMBOL}.JK`
- Fundamentals: `https://query1.finance.yahoo.com/v10/finance/quoteSummary/{SYMBOL}.JK`
- Rate limits: ~2000 req/hr (undocumented, we should respect ~1 req/s burst)
### Future (pluggable):
- IDX official API (if/when available)
- Alpha Vantage, Twelve Data, etc. via `idx config set provider ...`
---

## Symbol Resolution
- Input: `BBCA` → resolved to `BBCA.JK` (IDX suffix)
- Input: `BBCA.JK` → used as-is
- Default exchange suffix configurable: `idx config set exchange JK`
- Multiple symbols: comma-separated `BBCA,BBRI,BMRI` or space-separated where noted
---
## Output Strategy
### Global flags
```
-o, --output <FORMAT> Output format [default: table]
[table, json, csv, tsv]
--no-color Disable colored output
-q, --quiet Suppress non-essential output
-v, --verbose Increase verbosity
```
### Table mode (default, for humans)
```
$ idx stocks quote BBCA
SYMBOL PRICE CHG CHG% VOLUME MKT CAP 52W RANGE SIGNAL
BBCA.JK 9,875 +117 +1.20% 12.3M 1,215.2T ████████░░ upper
```
### JSON mode (for agents/scripts)
```json
$ idx -o json stocks quote BBCA
{
"symbol": "BBCA.JK",
"price": 9875,
"change": 117,
"change_pct": 1.20,
"volume": 12300000,
"market_cap": 1215200000000000,
"week52_high": 10250,
"week52_low": 7800,
"week52_position": 0.732,
"range_signal": "upper"
}
```
### CSV/TSV mode (for batch/spreadsheet)
```
$ idx -o csv stocks quote BBCA,BBRI
symbol,price,change,change_pct,volume,market_cap
BBCA.JK,9875,117,1.20,12300000,1215200000000000
BBRI.JK,4560,45,1.00,25600000,567800000000000
```
### Error handling
- Exit code 0 on success, non-zero on failure
- Table mode: human error on stderr
- JSON mode: `{"error": true, "code": "SYMBOL_NOT_FOUND", "message": "..."}`
---
## Technical Analysis Implementation
### Indicators (v0.1)
- **RSI(14)** — Relative Strength Index, 14-period
- **MACD(12,26,9)** — Moving Average Convergence Divergence
- **SMA(20,50,200)** — Simple Moving Averages
- **Volume analysis** — vs 20-day average
### Signal interpretation
Each indicator produces a signal: `bullish | bearish | neutral`
Overall technical signal derived from weighted consensus:
- RSI: overbought (>70) / oversold (<30) / neutral
- MACD: histogram direction + signal line cross
- Price vs SMA: above/below 50/200 day
### Fundamental metrics
- **Growth**: revenue growth, earnings growth YoY
- **Valuation**: trailing PE, forward PE, PB, EV/EBITDA, ROE, profit margin
- **Risk**: D/E ratio, current ratio, ROA
Each category produces an interpreted signal with the raw numbers.
---
## Screening Engine (v0.1)
Simple expression parser for filtering stocks:
```
idx screen query "pe < 15 and roe > 20"
idx screen query "market_cap > 100T and dividend_yield > 3"
idx screen query "rsi < 30" # oversold screen
```
### Available fields
`price`, `change_pct`, `volume`, `market_cap`, `pe`, `pb`, `roe`, `roa`,
`de_ratio`, `current_ratio`, `profit_margin`, `revenue_growth`,
`earnings_growth`, `dividend_yield`, `rsi`, `week52_position`
### Operators
`>`, `<`, `>=`, `<=`, `==`, `!=`, `and`, `or`
### Built-in presets
- `value` — PE < 15, PB < 1.5, ROE > 15
- `growth` — revenue growth > 20%, earnings growth > 20%
- `oversold` — RSI < 30, week52_position < 0.3
- `dividend` — dividend yield > 4%, payout sustainable
- `blue-chip` — market cap > 100T, ROE > 15
---
## Caching
- **Location**: `~/.cache/idx/`
- **Strategy**: file-based, keyed by (symbol, data_type, params)
- **Default TTL**: 5 minutes for quotes, 1 hour for fundamentals
- **Format**: binary (bincode/msgpack) for speed
- Configurable: `idx config set cache.quote_ttl 300`
---
## Configuration
### File: `~/.config/idx/config.toml`
```toml
[general]
exchange = "JK"
output = "table"
color = true
[cache]
quote_ttl = 300 # seconds
fundamental_ttl = 3600
[provider]
default = "yahoo"
# alpha_vantage_key = "..." # future
```
### Precedence
`flags > env vars > config file > defaults`
### Environment variables
```
IDX_OUTPUT=json
IDX_EXCHANGE=JK
IDX_CACHE_QUOTE_TTL=300
IDX_NO_COLOR=1

## Agent Skills
Inspired by [Google Workspace CLI's skills system](https://github.com/googleworkspace/cli/tree/main/skills), `idx-cli` ships a `skills/` directory with SKILL.md files that teach AI agents how to use the CLI effectively. No MCP, no JSON schema bloat — just markdown instructions that any agent framework can pick up.
### Structure
```
skills/
├── idx-shared/SKILL.md # Install block, common patterns, output modes
├── idx-quote/SKILL.md # Price lookup, multi-symbol quotes
├── idx-technical/SKILL.md # Technical analysis workflow
├── idx-fundamental/SKILL.md # Fundamental analysis (growth, valuation, risk)
├── idx-compare/SKILL.md # Multi-stock comparison
├── idx-screen/SKILL.md # Stock screening with expressions & presets
├── idx-ownership/SKILL.md # Ownership intelligence queries
├── idx-watchlist/SKILL.md # Watchlist management
├── idx-workflow-dd/SKILL.md # Due diligence workflow (chains multiple commands)
└── idx-workflow-sector/SKILL.md # Sector analysis workflow
```
### Skill anatomy
Each SKILL.md follows a consistent format:
```markdown
# idx-quote — Stock Price Lookup
## Install
<!-- Auto-install block for agent frameworks -->
```bash
cargo install idx-cli # or: nix run github:0xrsydn/idx-cli
```
## Commands
<!-- Exact commands with examples -->
idx stocks quote BBCA
idx stocks quote BBCA,BBRI,BMRI -o json
## Output format
<!-- What the agent should expect back -->
## Patterns
<!-- Common usage patterns, gotchas, tips -->
## See also
<!-- Related skills -->
```
### Integration with agent frameworks
```bash
# OpenClaw — symlink all skills
ln -s /path/to/idx-cli/skills/idx-* ~/.openclaw/skills/
# Or install specific skills
cp -r skills/idx-quote skills/idx-ownership ~/.openclaw/skills/
# Claude Code — skills are auto-discovered from repo
# Gemini CLI — same pattern as gws
```
### Design principles
1. **Self-contained** — each skill has everything an agent needs, no cross-references required
2. **Example-driven** — real commands with real output, not abstract descriptions
3. **Composable** — workflow skills reference atomic skills, agents can chain them
4. **Framework-agnostic** — plain markdown works with OpenClaw, Claude, Gemini, Cursor, etc.
---
## Open Questions
1. **Stock universe for screening** — Yahoo doesn't have a "list all IDX stocks" endpoint. We need a static list of IDX symbols (~800) bundled or fetched from IDX website. How to maintain?
2. **Rate limiting strategy** — batch requests vs sequential with delay? Should we parallelize multi-symbol queries?
3. **Offline mode** — serve from cache when network unavailable, or fail explicitly?
4. **Interactive shell** — worth building `idx shell` REPL in v0.1, or defer?
5. **Plugin system** — allow custom analyzers/data sources via dynamic loading, or keep it simple?

# IDX Ownership Intelligence Feature Design (KSEI >1% Dataset)
## 1) What I analyzed
### Source file
- URL: `https://www.idx.co.id/StaticData/NewsAndAnnouncement/ANNOUNCEMENTSTOCK/From_EREP/202603/95f8c4c8bc_848269e900.pdf`
- Saved to: `/var/lib/openclaw/projects/idx-cli/research/ownership_202603.pdf`
- Download note: direct `curl` got Cloudflare block HTML; download succeeded using browser-like headers via Python `urllib`.
### Parsing approach
- `pdftotext` not available in runtime.
- Used Node parser stack:
- `pdf-parse` for full-text sanity check
- `pdf2json` for coordinate-based extraction (critical for column integrity)
- Extracted row-level dataset to:
- `/var/lib/openclaw/projects/idx-cli/research/ownership_202603_rows.ndjson`
- `/var/lib/openclaw/projects/idx-cli/research/ownership_202603_analysis.json`
---
## 2) PDF structure analysis
### High-level structure
- Total pages: **73**
- First pages: cover letter/explanatory text from KSEI.
- Tabular section (core data): repeated row records with these headers:
```text
DATE
SHARE_CODE
ISSUER_NAME
INVESTOR_NAME
INVESTOR_TYPE
LOCAL_FOREIGN
NATIONALITY
DOMICILE
HOLDINGS_SCRIPLESS
HOLDINGS_SCRIP
TOTAL_HOLDING_SHARES
PERCENTAGE
```
### Observed dataset size (from parsed rows)
- Total ownership rows: **7,257**
- Unique tickers (`share_code`): **955**
- Unique issuer names: **956** (1 extra due naming variant/noise)
- Unique investor names (raw uppercased): **5,195**
- As-of date: **27-Feb-2026** for all rows in this release
### Example extracted rows
```json
{
"date": "27-Feb-2026",
"share_code": "AADI",
"issuer_name": "ADARO ANDALAN INDONESIA Tbk",
"investor_name": "ADARO STRATEGIC INVESTMENTS",
"investor_type": "CP",
"local_foreign": "L",
"nationality": "",
"domicile": "INDONESIA",
"holdings_scripless": "3.200.142.830",
"holdings_scrip": "0",
"total_holding_shares": "3.200.142.830",
"percentage": "41,10"
}
```
```json
{
"date": "27-Feb-2026",
"share_code": "AALI",
"issuer_name": "ASTRA AGRO LESTARI Tbk",
"investor_name": "PT ASTRA INTERNATIONAL TBK",
"investor_type": "CP",
"local_foreign": "L",
"nationality": "",
"domicile": "INDONESIA",
"holdings_scripless": "0",
"holdings_scrip": "1.533.682.440",
"total_holding_shares": "1.533.682.440",
"percentage": "79,68"
}
```
### Data quality notes
- Missingness:
- `investor_type` missing: 244 rows
- `local_foreign` missing: 244 rows
- `nationality` missing: 4,240 rows
- `domicile` missing: 1,053 rows
- Investor types observed most: `CP`, `ID`, `IB`, `MF`, `SC`, `OT`, `IS`
- Raw entity names have normalization issues (`PT`, punctuation, case, suffix variations).
---
## 3) Analytical potential from this release
### Cross-holder signal (same investor across many tickers)
Top examples (raw name grouping):
- UOB KAY HIAN PRIVATE LIMITED: **66** tickers
- BANK OF SINGAPORE LIMITED: **38**
- PT. ASABRI (Persero): **33**
- DJS Ketenagakerjaan (JHT): **31**
- UBS AG Singapore Branch: **27**
This already forms a strong bipartite graph: `entity -> owns -> ticker`.
### Concentration metrics per ticker
Examples from parsed results:
- Very concentrated:
- `IBST`: 1 holder >1%, total captured 99.95%
- `SUPR`: largest holder 97.33%
- More dispersed among >1% holders:
- `BBRI`: total >1% captured 5.86%
- `ADHI`: 7.37%
- `BBNI`: 7.95%
### Breadth metric
- Tickers with most >1% holders in this snapshot:
- `CARS` (28), `INPC` (28), `BOGA` (27), etc.
---
## 4) Proposed data model (SQLite-first)
Use SQLite for local analytics in `idx-cli` (fast, portable, no server dependency).
### Core tables
```sql
-- One PDF release/event
CREATE TABLE ownership_release (
id INTEGER PRIMARY KEY,
source_url TEXT NOT NULL,
source_file_sha256 TEXT NOT NULL UNIQUE,
as_of_date TEXT NOT NULL, -- YYYY-MM-DD
published_at TEXT,
fetched_at TEXT NOT NULL,
parser_version TEXT NOT NULL,
row_count INTEGER NOT NULL,
metadata_json TEXT
);
CREATE TABLE issuer (
id INTEGER PRIMARY KEY,
ticker TEXT NOT NULL UNIQUE,
issuer_name_raw TEXT NOT NULL,
issuer_name_norm TEXT NOT NULL
);
CREATE TABLE entity (
id INTEGER PRIMARY KEY,
canonical_name TEXT NOT NULL,
canonical_name_norm TEXT NOT NULL UNIQUE,
entity_kind TEXT, -- company/person/fund/gov/unknown
country_hint TEXT,
created_at TEXT NOT NULL,
updated_at TEXT NOT NULL
);
-- Raw name variants resolved to entity
CREATE TABLE entity_alias (
id INTEGER PRIMARY KEY,
entity_id INTEGER NOT NULL REFERENCES entity(id),
alias_raw TEXT NOT NULL,
alias_norm TEXT NOT NULL,
confidence REAL NOT NULL, -- 0..1
method TEXT NOT NULL, -- exact/manual/fuzzy/rule
UNIQUE(entity_id, alias_norm)
);
CREATE TABLE ownership_fact (
id INTEGER PRIMARY KEY,
release_id INTEGER NOT NULL REFERENCES ownership_release(id),
issuer_id INTEGER NOT NULL REFERENCES issuer(id),
entity_id INTEGER NOT NULL REFERENCES entity(id),
investor_name_raw TEXT NOT NULL,
investor_type TEXT,
local_foreign TEXT,
nationality TEXT,
domicile TEXT,
holdings_scripless INTEGER NOT NULL,
holdings_scrip INTEGER NOT NULL,
total_holding_shares INTEGER NOT NULL,
percentage_bps INTEGER NOT NULL, -- e.g. 41.10% => 4110
-- one row per entity/ticker/release/rawname (can enforce stronger uniqueness later)
UNIQUE(release_id, issuer_id, investor_name_raw)
);
```
### Useful indexes
```sql
CREATE INDEX idx_fact_release_issuer ON ownership_fact(release_id, issuer_id);
CREATE INDEX idx_fact_release_entity ON ownership_fact(release_id, entity_id);
CREATE INDEX idx_fact_pct ON ownership_fact(release_id, percentage_bps DESC);
CREATE INDEX idx_alias_norm ON entity_alias(alias_norm);
```
---
## 5) End-to-end pipeline design (PDF → queryable intelligence)
1. **Fetch**
- Download announcement PDF using robust HTTP headers.
- Store raw file in data dir + SHA256.
2. **Parse (bronze)**
- Coordinate extraction from PDF (x/y text cells).
- Emit raw row JSON with strict schema + parser warnings.
3. **Normalize (silver)**
- Parse numerics:
- `1.533.682.440` → integer shares
- `79,68` → 7968 bps
- Standardize date: `27-Feb-2026` → `2026-02-27`
- Normalize text fields (trim, whitespace, uppercase key columns).
4. **Resolve entities (gold)**
- Deterministic normalization rules (`PT.`, commas, suffixes, punctuation).
- Alias mapping table + manual overrides.
- Fuzzy match only with high threshold + review queue.
5. **Load SQLite**
- UPSERT `issuer`, `entity`, `entity_alias`, `ownership_fact`.
- Keep release snapshots immutable for time-series diffs.
6. **Derive marts/materialized views**
- `v_ticker_concentration` (HHI, top1, top3, sum>1)
- `v_entity_cross_holdings` (#tickers, total bps)
- `v_pair_coownership` (entity pairs co-appearing across tickers)
---
## 6) Entity graph design
### Graph model
- **Node types**:
- `Entity` (investor)
- `Ticker` (issuer)
- **Edge**: `OWNS` with attributes
- `release_id`, `percentage_bps`, `shares_total`, `investor_type`, `local_foreign`
### Derived graph analytics
1. **Cross-holders**: entities with high ticker degree.
2. **Co-ownership network**:
- Build `Entity --co_owns--> Entity` weighted by number of shared tickers and summed min(%).
3. **Cluster detection**:
- Louvain / connected components on co-ownership graph.
4. **Concentration**:
- per ticker `top1`, `top3`, `sum_pct_gt1`, `HHI`.
5. **Temporal graph** (when monthly releases accumulate):
- edge delta (`+/- bps`), entry/exit events, emerging cluster shifts.
---
## 7) CLI command proposals
Integrate as a new top-level group in `SPEC.md` style:
```text
idx ownership
├── ticker <SYMBOL> # holders >1% for ticker
├── entity <NAME_OR_ID> # what this entity owns
├── cross-holders # entities with widest cross-ownership
│ [--top 20] [--min-tickers 5]
├── concentration # ranking by concentration metrics
│ [--by top1|top3|sum|hhi] [--top 20] [--least]
├── clusters # co-ownership clusters
│ [--min-shared 2]
├── changes # compare two releases
│ --from <YYYY-MM-DD> --to <YYYY-MM-DD>
├── releases # available snapshots
├── import # parse & load latest PDF(s)
│ [--url <PDF_URL>] [--file <PATH>] [--as-of <DATE>] [--force]
└── resolve # alias/entity management
├── list-unresolved
├── map <ALIAS> <ENTITY>
└── merge <ENTITY_A> <ENTITY_B>
```
### Example UX
```bash
$ idx ownership ticker BBCA
AS OF: 2026-02-27 | TICKER: BBCA
RANK INVESTOR TYPE L/F SHARES %
1 PT ... CP L 12,345,678,900 54.32
2 ...
```
```bash
$ idx -o json ownership entity "UOB KAY HIAN PRIVATE LIMITED"
{
"entity": "UOB KAY HIAN PRIVATE LIMITED",
"as_of": "2026-02-27",
"ticker_count": 66,
"holdings": [ ... ]
}
```
---
## 8) Architecture recommendations
### Local-first (recommended MVP)
- DB path: `~/.local/share/idx/ownership.db` (or XDG equivalent)
- Raw files cache: `~/.cache/idx/ownership/raw/`
- Parsed snapshots: `~/.cache/idx/ownership/parsed/`
Pros: offline-capable, instant query, aligns with existing CLI/caching philosophy in `SPEC.md`.
### Update model
- `idx ownership import` checks known URL(s) or accepts explicit URL/file.
- De-duplicate by SHA256 + as_of_date.
- Keep all snapshots to unlock `changes` and trend analytics.
### Optional future API mode
- If multi-user/team usage needed, same schema can back a lightweight API service.
- Keep CLI query layer repository-backed so data source can be local SQLite or remote API.
---
## 9) Entity resolution challenges (critical)
1. **Name variants**: `PT X`, `PT. X`, `X PT`, punctuation/case.
2. **Corporate suffix permutations**: `TBK`, `Tbk`, `(PERSERO)`, etc.
3. **Custodian omnibus names** may mask underlying beneficial owners.
4. **Person name ambiguity** (same personal names).
5. **Cross-language spelling** and abbreviations.
6. **Corporate group mapping** (subsidiary vs parent): separate from exact legal entity identity.
### Practical strategy
- Phase 1: conservative exact+rule normalization (high precision).
- Phase 2: human-reviewed alias map.
- Phase 3: optional fuzzy suggestions with confidence score, never auto-merge below threshold.

## 10) Integration with current `idx-cli` SPEC
Current `SPEC.md` is quote/fundamental/technical-centric. Ownership feature fits as a differentiated analytics vertical:
- Add new top-level command group: `ownership`
- Reuse global output modes: `table|json|csv|tsv`
- Reuse config precedence (flags > env > config)
- Extend config:
```toml
[ownership]
db_path = "~/.local/share/idx/ownership.db"
raw_cache_dir = "~/.cache/idx/ownership/raw"
parsed_cache_dir = "~/.cache/idx/ownership/parsed"
entity_resolution_mode = "conservative"
auto_import = false
```
- Add milestone slice (proposed):
- **v0.2.5**: `ownership import`, `ownership ticker`, `ownership entity`
- **v0.3**: concentration/cross-holder rankings, releases/changes
- **v0.4+**: clustering/graph exports and manual resolution workflow
---
## 11) Open questions before implementation
1. Official stable source URL pattern for future monthly releases?
2. Will data always be PDF only, or also XLS/CSV endpoint?
3. Canonical meaning of investor type codes (`CP`, `ID`, `IB`, etc.) — need official codebook.
4. Should ADR/dual-listing/suspended symbols be filtered in CLI output?
5. Entity resolution governance: where to store curated alias mappings in-repo vs user-local?
