A real first session with gcontext

This page is generated from an actual test run on June 11, 2026: a real model dropped into a fresh, empty workspace. Nothing here is mocked or hand-written. The transcripts are complete; secrets are masked and the sandbox temp prefix is shortened to workspace/-relative paths, nothing else is touched.

Setup

What the user did

Three copy-paste steps. This is the entire setup.

  1. Initialize the workspace

    gcontext init
  2. Put the keys in .env

    SUPABASE_URL=https://your-project.supabase.co
    SUPABASE_SECRET_KEY=sb_secret_...

    Only the names SUPABASE_URL and SUPABASE_SECRET_KEY ever appear in module files. The values stay in the gitignored .env.

  3. Say the prompt

    Create a supabase integration module for our Supabase project and load it
    into the workspace. The project URL and a secret API key are already in
    .env as SUPABASE_URL and SUPABASE_SECRET_KEY. Declare both by name in
    module.yaml and NEVER copy their values into any module file. In info.md,
    document how to call the Supabase REST API (PostgREST) with those
    variables: base path /rest/v1/, the apikey and Authorization headers, and
    an example table query.

    The test run appends one sandbox-only clause (the gcontext CLI binary is not installed inside the sandbox, so the agent creates the files by hand). You can see it at the end of the prompt in the transcript below; everything else is exactly this prompt.

Session 1 · the agent builds the integration

What the agent did, step by step

Every row below is one real tool call. The one-line summaries are generated from the call itself; click any row for the raw call and result.

the prompt
Create a supabase integration module for our Supabase project and load it
into the workspace. The project URL and a secret API key are already in
.env as SUPABASE_URL and SUPABASE_SECRET_KEY. Declare both by name in
module.yaml and NEVER copy their values into any module file. In info.md,
document how to call the Supabase REST API (PostgREST) with those
variables: base path /rest/v1/, the apikey and Authorization headers, and
an example table query. The gcontext CLI is not installed here, so create the module files and the context/ symlink by hand following context/structure.md and context/principles.md.

1It reads the workspace rules first

Before writing anything, the agent walks the generated docs: how modules are structured, where secrets live, what an integration needs.

I'll start by reading the gcontext docs as AGENTS.md instructs, then look at the workspace layout.

5	These are the rules for creating, editing, or extending modules.
6	
7	## Module locations
8	
9	Modules live at `modules-repo/<slug>/`. The `context/` directory contains symlinks for the subset of modules currently loaded into the active workspace — **it is a view, not a storage location.**
10	
11	Two operations that look similar but are NOT the same:
12	
13	- **Create / edit a module.** You write files at `modules-repo/<slug>/...`. This is the only kind of write you perform.
14	- **Load a module into the workspace.** This creates a symlink inside `context/`. It is managed by the `gcontext` CLI, not by you.
15	
16	Each module is a folder with at least `module.yaml` and `llms.txt`.
17	
18	## Reading context before modifying
19	
20	Before answering anything that references or implies a topic likely covered by an existing module, read that module's `llms.txt` first. If `llms.txt` declares a `## Where to write` section, that section governs where any subsequent appends go (path, naming pattern, template). Do NOT invent a new location.
21	
22	If no module matches, you may answer from general knowledge — but if the conversation produces durable content (a finding, a note worth keeping, a new procedure), propose a new module rather than silently dropping it.

5It reports back

agent
The supabase integration module is created and loaded into the workspace. Since the gcontext CLI isn't installed, I emulated `gcontext load` by hand. What was created: - `modules-repo/supabase/module.yaml`: declares `name: supabase` and the two secrets by name only (`SUPABASE_URL`, `SUPABASE_SECRET_KEY`). The `kind: integration` field is omitted because it's the default per `structure.md`. - `modules-repo/supabase/info.md`: follows the integration template sections (Purpose, Where it lives, Auth & access, Key entities, Operations, Examples). It documents the `/rest/v1/` base path, the requirement to send the key in both the `apikey` and `Authorization: Bearer` headers, common PostgREST filters (`eq.`, `order`, `limit`, etc.), and runnable examples: a curl table query that sources `.env`, a stdlib-only Python query run with `uv run`, and an insert with `Prefer: return=representation`. It also notes the secret key bypasses Row Level Security, so it's server-side only. - `modules-repo/supabase/llms.txt`: module index with one-line descriptions plus a `## Where to write` section seeding the `notes/<date-slug>.md` growth folder. - `context/supabase -> ../modules-repo/supabase` symlink, verified to resolve. I also updated the two generated index files a real `gcontext load` would rewrite, so the module is actually discoverable: `context/llms.txt` now lists the module, and the "Loaded modules" table in `context/system.md` shows it. The next real `gcontext load`/`unload` will regenerate both, which is fine. No secret values appear anywhere in the module: I verified the files reference only the variable names. One note: my attempt to read `.env` (names only, via `cut`) was denied, so I took the variable names from your message as given; if either name differs in `.env`, `module.yaml` and `info.md` need the same one-word fix.
Session finished: 18 turns, 138s, $1.01

The result

The module, exactly as the agent wrote it

Three files make an integration. Note that module.yaml declares secret names only, never values.

modules-repo/supabase/info.md81 lines
# supabase

## Purpose
REST access to our Supabase project's Postgres database through the PostgREST API, authenticated with the project's secret API key.

## Where it lives
The project base URL is the value of `SUPABASE_URL` (stored in `.env` at the project root, never in this module). The REST API is served under the base path:

```
{SUPABASE_URL}/rest/v1/
```

## Auth & access
Two secrets, declared by name in `module.yaml`, values read from `.env`:

- `SUPABASE_URL`: the Supabase project URL
- `SUPABASE_SECRET_KEY`: a secret API key; it bypasses Row Level Security, so it is server-side only and must never be exposed to a browser, logged, or written into module files

Every REST request must send the key in both headers:

```
apikey: <value of SUPABASE_SECRET_KEY>
Authorization: Bearer <value of SUPABASE_SECRET_KEY>
```

In scripts, read both values via `os.environ`; in shell, source `.env` first. Never hardcode the values.

## Key entities
- **Tables and views**: each exposed table or view in the `public` schema is available at `{SUPABASE_URL}/rest/v1/<table>`
- **Rows**: returned as JSON arrays of objects; selected, filtered, ordered, and paginated via query parameters
- **RPC functions**: exposed Postgres functions are callable at `{SUPABASE_URL}/rest/v1/rpc/<function>` with a JSON body of arguments

## Operations
- **Read rows**: `GET /rest/v1/<table>?select=<columns>&<filters>`
- **Filter**: `?<column>=eq.<value>` (also `gt.`, `gte.`, `lt.`, `lte.`, `neq.`, `like.`, `in.(a,b)`)
- **Order and paginate**: `?order=<column>.desc&limit=<n>&offset=<n>`
- **Insert**: `POST /rest/v1/<table>` with a JSON object (or array) body, plus `Content-Type: application/json`; add `Prefer: return=representation` to get the inserted rows back
- **Update**: `PATCH /rest/v1/<table>?<filter>` with a JSON body of changed columns; always include a filter
- **Delete**: `DELETE /rest/v1/<table>?<filter>`; always include a filter, an unfiltered DELETE affects every row

## Examples

Query a table with curl (loads secrets from `.env`, never inlines them):

```bash
set -a; source .env; set +a
curl "$SUPABASE_URL/rest/v1/todos?select=id,title,done&done=eq.false&order=id.desc&limit=10" \
  -H "apikey: $SUPABASE_SECRET_KEY" \
  -H "Authorization: Bearer $SUPABASE_SECRET_KEY"
```

Same query from Python (stdlib only, run with `uv run`):

```python
# uv run query_todos.py
import json
import os
import urllib.request

base = os.environ["SUPABASE_URL"].rstrip("/")
key = os.environ["SUPABASE_SECRET_KEY"]

req = urllib.request.Request(
    f"{base}/rest/v1/todos?select=id,title,done&done=eq.false&limit=10",
    headers={"apikey": key, "Authorization": f"Bearer {key}"},
)
with urllib.request.urlopen(req) as resp:
    print(json.dumps(json.load(resp), indent=2))
```

Insert a row:

```bash
set -a; source .env; set +a
curl -X POST "$SUPABASE_URL/rest/v1/todos" \
  -H "apikey: $SUPABASE_SECRET_KEY" \
  -H "Authorization: Bearer $SUPABASE_SECRET_KEY" \
  -H "Content-Type: application/json" \
  -H "Prefer: return=representation" \
  -d '{"title": "buy milk", "done": false}'
```

Then a brand-new session answered a real question

A second session starts with zero context: a new conversation that has never seen the project. It gets one question: Using the supabase integration module in this workspace, find out how many users are in the users table, and reply with only the number.

3	## Purpose
4	REST access to our Supabase project's Postgres database through the PostgREST API, authenticated with the project's secret API key.
5	
6	## Where it lives
7	The project base URL is the value of `SUPABASE_URL` (stored in `.env` at the project root, never in this module). The REST API is served under the base path:
8	
9	```
10	{SUPABASE_URL}/rest/v1/
11	```
12	
13	## Auth & access
14	Two secrets, declared by name in `module.yaml`, values read from `.env`:
15	
16	- `SUPABASE_URL`: the Supabase project URL
17	- `SUPABASE_SECRET_KEY`: a secret API key; it bypasses Row Level Security, so it is server-side only and must never be exposed to a browser, logged, or written into module files
18	
19	Every REST request must send the key in both headers:
20	
21	```
22	apikey: <value of SUPABASE_SECRET_KEY>
23	Authorization: Bearer <value of SUPABASE_SECRET_KEY>
24	```
25	
26	In scripts, read both values via `os.environ`; in shell, source `.env` first. Never hardcode the values.
27	
28	## Key entities
29	- **Tables and views**: each exposed table or view in the `public` schema is available at `{SUPABASE_URL}/rest/v1/<table>`
30	- **Rows**: returned as JSON arrays of objects; selected, filtered, ordered, and paginated via query parameters
31	- **RPC functions**: exposed Postgres functions are callable at `{SUPABASE_URL}/rest/v1/rpc/<function>` with a JSON body of arguments
32	
33	## Operations
34	- **Read rows**: `GET /rest/v1/<table>?select=<columns>&<filters>`

3	# Secrets
4	
5	Secrets are environment variables. Modules declare which variables they need in `module.yaml` under the `secrets:` list — variable names only, never values.
6	
7	## How it works
8	
9	1. Check a module's `module.yaml` for its `secrets:` list
10	2. Values live in `.env` at the project root (gitignored, never committed)
11	3. `.env.example` is auto-generated with all required variable names
12	4. Run `gcontext env` to check which variables are set or missing
13	
14	## Rules
15	
16	- Never hardcode secret values in module files
17	- Never commit `.env` to version control
18	- Access secrets via `os.environ` in scripts
19

The module docs show how to query PostgREST. I'll request an exact count of the users table.

2One API call, exact count

Straight from the module docs: a count request against the REST API, no table dump.

BashRan a command: Get exact row count of users table via PostgREST
call
{
  "command": "set -a; source .env; set +a; curl -s -I \"$SUPABASE_URL/rest/v1/users?select=id\" -H \"apikey: $SUPABASE_SECRET_KEY\" -H \"Authorization: Bearer $SUPABASE_SECRET_KEY\" -H \"Prefer: count=exact\" -H \"Range: 0-0\" | grep -i content-range",

users, independent Supabase API call

The numbers match. The test fails if they do not.
