Zephex Tools

The ten codebase intelligence tools — full reference for agents and developers.

Same tools, same API key, same credits, three surfaces:

Surface	Repo	Best when
Editor MCP	zephex-MCPs	Cursor / Claude Code / Codex / OpenCode
Local CLI	zephex-cli	Shell, monorepos, `deep --json`, CI
Web terminal	zephex-web-terminal	Browser demo, no install, public GitHub

This repo is the deep tool catalog. Product overview lives on zephex-MCPs. Endpoint: https://zephex.dev/mcp. Free tier: 555 req/mo.

get_project_context → find_code → read_code → [edit] → check_test
         ↘ explain_architecture when the change spans modules
              check_package before any new dependency
              project_memory when you learn something non-obvious
              keep_thinking only if still stuck after real tool use
              audit_headers only on a user-supplied live URL
              Zephex_dev_info for generic playbooks (not their private code)

Canonical names (only these ten)

#	Tool	One-liner
1	`get_project_context`	Stack, scripts, auth, deploy — one topic per call
2	`find_code`	Ranked search: snippet · symbol · concept · everywhere
3	`read_code`	AST symbol / file batch / outline / scan / smell
4	`explain_architecture`	Wiring map, layers, edges; deep + Mermaid
5	`check_package`	Registry safety · upgrade notes · CVEs (12 ecosystems)
6	`check_test`	Test Pulse — run, failures, fix_prompt, missing
7	`audit_headers`	Live HTTPS grade (user-supplied URL only)
8	`project_memory`	remember / recall / list / forget across sessions
9	`keep_thinking`	Structured multi-step reasoning + loop detection
10	`Zephex_dev_info`	Expert playbooks (Stripe, RLS, …) — not private code

Dead names (removed — never document as live)

Wrong	Right
`scope_task`	`find_code` + architecture / CLI `deep`
`inspect_url`	`audit_headers`
`audit_package`	`check_package` with `task`
bare `thinking`	`keep_thinking`

Server may still alias some old names; do not teach them as product names.

Project source (almost every code tool)

Pass one of:

Mode	Example
Local disk (stdio / CLI)	`path: "/absolute/to/project"`
Public GitHub	`path: "github:owner/repo"` or full HTTPS URL
No disk (hosted only)	`inline_files: { "src/a.ts": "<full body>" }`

Hosted MCP often blocks absolute laptop paths — use GitHub URL or inline_files.

Default agent chain

1. get_project_context  topic=identity   (then run, then auth if needed)
2. find_code            when location unknown
3. read_code            when path or symbol known
4. [agent edits in the editor]
5. check_test           task=run → then free failures / fix_prompt on session_id

Situation	Tool
Cross-cutting feature (auth, billing, monorepo)	`explain_architecture`
Before `npm install` / version bump	`check_package`
User pasted a production URL	`audit_headers`
“Remember we use X” / “what did we decide”	`project_memory`
2+ failed debug attempts, high blast radius	`keep_thinking`
Generic “how do Stripe webhooks work”	`Zephex_dev_info`

Tool reference

Credits below are approximate (verify in dashboard / response meta). Free pool is shared across MCP + CLI + web terminal.

1. `get_project_context` — Project Context

~7 credits · start here on any unknown repo

Docs: get-project-context

Reads manifests (package.json, pyproject.toml, Cargo.toml, go.mod, …) and returns one focused topic per call. Not for symbol search or file bodies.


Topics	`identity` · `framework` · `backend` · `frontend` · `database` · `auth` · `deploy` · `run` · `structure` · `integrations` · `security`
Input	`path` or `inline_files`; `topic`; `detail_level` brief\|standard\|full; optional `force`, `include_structure`, `focus_on`
Output	`topic`, `focus`, `summary`, `data.key_paths`, `hint`, `related_topics`, `next_calls`
When	First touch before guessing install/test commands
CLI	`zephex overview` · `zephex get-context` / `context` / `stack` · `zephex deep` (composite)

Example (MCP)

{
  "path": "github:owner/repo",
  "topic": "identity",
  "detail_level": "standard"
}

Example (CLI)

cd your-app
zephex overview
zephex get-context --topic run
zephex deep "add rate limiting" --json   # agent packet schema_version: 1

Do not use for find/read/test — those are other tools.

2. `find_code` — Code Search

~5 credits · location unknown

Docs: find-code

Ranked search inside the project. Pick intent, not a pile of knobs.

Intent	Use for
`snippet`	Pasted line of code
`symbol`	Known name (function, class, const)
`concept`	Topic + optional `also_try` synonyms
`everywhere`	Rename map (`whole_word` recommended)


Input	`query` (required); `path`; `intent`; `also_try[]`; `include` code\|docs\|config\|data\|all; `file_pattern`; `whole_word`; `case_sensitive`; `response_format`
Output	`matches` / `all_occurrences`, `files_hit`, `files_summary`, `next_calls`
When	Unknown location; rename before edit; multi-keyword hunt
CLI	`zephex find "…"` · `find-code` · `defs` · `rename` · `paste`

Example (MCP)

{
  "path": "github:owner/repo",
  "query": "rate limit middleware",
  "intent": "concept",
  "also_try": ["throttle", "ratelimit"]
}

Example (CLI)

zephex find "auth middleware"
zephex rename OldName   # intent everywhere

Then read_code on the top hit from next_calls.

3. `read_code` — Code Reader

~5 credits · path or symbol known

Docs: read-code

Surgical AST read with a token budget. Prefer after find_code.

Mode	Does
`symbol`	Extract by name (default)
`file`	Batch 1–20 paths
`outline`	Structural TOC — use first on 300+ line files
`scan`	Keywords across `files[]`
`smell`	Bug patterns on focus files
`callers` / `blast_radius` / `dead_code`	Local disk only


Input	`path`; `mode`; `target` / `symbol_id` / `targets[]`; `files[]`; `offset_line` / `limit_lines`; `compact`; `inline_files`
Output	signatures, bodies, usages, `hint`, `next_calls`
When	Known symbol or files from find_code
CLI	`zephex read` · `outline` · `symbol` · `summarize` · `files`

Example (MCP)

{
  "path": "github:owner/repo",
  "mode": "outline",
  "files": ["src/middleware/auth.ts"]
}

Tips: files under ~50 lines → native editor Read is fine. Batch file mode returns every path in one call. Pass max_results: 10 when batching many targets.

4. `explain_architecture` — Architecture Analyzer

~7 credits · cross-cutting change

Docs: explain-architecture

How modules wire together — not full file bodies. Seeds via concept search + import graph.


Input	`path`; `concern` (any label) or `seed_files[]`; `focus` api\|auth\|integrations\|database\|security\|full; `mode` overview\|deep\|audit; `subpath` for monorepos
Output	`concern_cluster`, `layer_map`, `entry_points`, `integration_map`, `auth_flow`; deep adds `request_flows` + Mermaid
When	“How does auth / billing / this feature span the repo?”
CLI	`zephex architecture` · `arch [--focus auth]`

Example (MCP)

{
  "path": "github:owner/repo",
  "concern": "authentication",
  "mode": "deep"
}

Example (CLI)

zephex architecture
zephex arch --focus auth

5. `check_package` — Package Check

~5 credits · before install or bump

Docs: check-package

Live registry across 12 ecosystems. One tool, multiple tasks (not a separate “audit_package”).

Task	Does
`check`	Exists / typosquat / CVE gate
`security`	CVEs only
`upgrade` / `migrate`	Breaking changes, migration steps, examples from GitHub releases
`debug`	Advisories + extra detail


Input	`package` (required); `task`; `version` / `from_version`; `source` github:owner/repo\|local; `ecosystem`
Output	exists, CVEs, risk_signals, breaking_changes, hint
When	“Is X safe?” · “How do I upgrade Next?”
CLI	`zephex safe lodash` · `zephex check-package next --task upgrade --from-version 14`

Example (MCP)

{
  "package": "lodash",
  "task": "check"
}

{
  "package": "next",
  "task": "upgrade",
  "from_version": "14.2.0",
  "source": "github:owner/repo"
}

If data.exists: false → do not install.

6. `check_test` — Test Pulse

~1 credit per hosted run; follow-ups free with session_id

Docs: test-pulse

Executes the detected test runner and returns agent-native health — not task scoping.

Task	Credits	Does
`run`	~1 hosted	Run suite, return health + `session_id`
`detect` / `missing`	0	Inventory / test-gap scan
`failures` · `list` · `why` · `fix_prompt` · `status` · …	0	After a run, on `session_id`


Input	`path`; `task`; `session_id`; optional `area` / `file_filter` / `diff_base` / `with_coverage`
Output	`health`, `broken_areas`, `fix_first`, `failure_clusters`, `blind_spots`, `session_id`
When	After edits, before push, “do tests pass?”
CLI	`zephex test` · `zephex check test failures` · `zephex check test fix-prompt --copy`

Example (MCP)

{ "path": "github:owner/repo", "task": "run" }

{ "task": "failures", "session_id": "<from run>" }

Example (CLI)

zephex test
zephex check test failures
zephex check test fix-prompt --copy

Hosted: public GitHub or inline_files. Local absolute paths on hosted MCP are blocked; stdio/CLI runs on your machine.

7. `audit_headers` — Site Audit

~5 credits · user pastes a live URL

Docs: audit-headers

Public URL intelligence on Zephex servers: security grade A–F, health, tech stack, optional secret scan. Blocks localhost / private IPs.


Input	`url` (required); `scan_mode` quick\|thorough; `scan_depth` quick\|deep; `probe_engine` fetch\|browser; `timeout_ms`
Output	`plain_summary`, grade, `site_verdict`, trust score, tech, secrets, headers
When	Post-deploy, “is it up”, security headers
CLI	`zephex check url https://example.com` · `site`

Example (MCP)

{
  "url": "https://example.com",
  "scan_mode": "quick",
  "probe_engine": "fetch"
}

Not for repo code (find_code) or tests (check_test).

8. `project_memory` — Project Memory

~1–4 credits · across sessions

Docs: project-memory

Persist decisions, gotchas, goals, conventions per project path.

Action	Does
`remember`	Save (title ≤80, content ≤500)
`recall`	Keyword search
`list`	Titles
`forget`	By id


Types	decision · gotcha · goal · preference · area_fact · convention
When	User says remember/recall; after non-obvious fix
CLI	`zephex remember` · `recall` · `memory list`

Example (MCP)

{
  "action": "remember",
  "path": "github:owner/repo",
  "title": "Auth uses JWT in cookies",
  "content": "Access token 15m, refresh 7d, SameSite=Strict",
  "type": "decision"
}

Scoped by project — not a global dump. Paraphrase facts; do not paste whole files. Not a substitute for get_project_context.

9. `keep_thinking` — Keep Thinking

~1–4 credits · stuck / high blast radius

Docs: keep-thinking

Multi-call reasoning scaffold with loop detection and risk gates. Not a replacement for search/read.


Required	`thought`, `thoughtNumber`, `totalThoughts`, `nextThoughtNeeded`, `confidence`, `thoughtType`
Useful	`goalAnchor` (after thought 2), `lastActions[]`, `sessionId`
When	Auth/billing/schema edits; 2+ failed debug attempts; 3+ file tasks
CLI	`zephex think "…"` · `reason` (one-shot; multi-turn is editor-native)

Pass lastActions or loop detection is weak. Close with nextThoughtNeeded: false. Cap ~10 thoughts/session.

10. `Zephex_dev_info` — Expert playbooks

~2–5 credits · generic patterns only

Docs: zephex-dev-info

Internal knowledge base: Stripe webhooks, Supabase RLS, CSP, Next.js auth, mobile signing, etc. Not the user’s private repo.


Flow	`operation: search` → then `operation: get` with returned `slug`
Categories	databases · security · frontend · backend · auth · mobile · android · payments
When	After repo tools if you still need a standard playbook
CLI	`zephex docs "…"` · `ask "…"`

Complements get_project_context. Not for package registry intel (check_package).

CLI map (Mode 2)

Same backend. Type these in a real shell after cd into the project (or --cwd).

You type	MCP tool
`overview` / `deep` / `get-context`	`get_project_context` (+ composites)
`find` / `find-code` / `rename`	`find_code`
`read` / `outline` / `symbol` / `files`	`read_code`
`architecture` / `arch`	`explain_architecture`
`safe` / `check-package`	`check_package`
`test` / `check test …`	`check_test`
`check url` / `site`	`audit_headers`
`remember` / `recall`	`project_memory`
`think` / `reason`	`keep_thinking`
`docs` / `ask`	`Zephex_dev_info`
`structure --agent`	local layout (0 credits)
