# Agentic Engineering Protocol

This file binds the agentic engineering runtime for every Codex session in this repository. The
full methodology (delegation, risk classification, activation preflight, Skeptic loop, quality
gates, agent definitions) loads separately, on trigger, via the `dinostack` skill - see "Load the
methodology on trigger" below.

## Codex runtime binding preamble

Before following any operational instruction below, establish these bindings in order:

1. Preserve the absolute invocation directory, then bind `AE_PROJECT_DIR` to its repository root
   (`git rev-parse --show-toplevel`) when it is inside a Git repository, otherwise to that verified
   absolute invocation directory. Do this before changing directories.
2. Select the active Codex config directory from the first non-empty runtime source in this order:
   `AGENTIC_CONFIG_DIR`, then `CODEX_HOME`, then the standard Codex config directory beneath a
   validated absolute `HOME`. Require the selected path to resolve to a real current-user-owned
   directory that is not group/world writable, then bind `AE_CODEX_CONFIG_DIR` to it. Profile
   identity operations use only the already-validated `$AE_CODEX_CONFIG_DIR` runtime binding;
   the active profile identity file is `$AE_CODEX_CONFIG_DIR/identity.yml`.
3. Inspect `AGENTS.md` beneath that selected config directory without following an unchecked final
   path. Require the installed entry to be a symlink whose physical target is the regular
   `.codex/AGENTS.md` file beneath a repository candidate whose `content/SKILL.md`, `.codex/`
   directory, and executable `bin/ds-codex-dispatch` form the DinoStack repository signature.
   After those checks, bind `AE_REPO_DIR` to that physical repository root. Never infer it from the
   process working directory.
4. When an explicit config source selected the Codex directory, bind `AE_ACTIVATION_CONFIG` to
   `agentic-engineering.json` beneath that directory. On the standard default install, bind
   `AE_ACTIVATION_CONFIG` to `agentic-engineering.json` beneath the standard shared Claude config
   directory under the validated `HOME`. Require the activation file to be a real, current-user-owned
   regular file that is not group/world writable.
5. Then bind `AE_SHARED_CONFIG_DIR` to the validated real parent directory of that activation file.
   It must be current-user-owned and not group/world writable.

If any binding cannot be established exactly, fail closed before executing the methodology. These
rules mirror the native-skill resource-resolution contract and prevent project paths, repository
resources, and shared user configuration from being conflated. After locating the validated
dispatcher, evaluate the same contract with
`$AE_REPO_DIR/bin/ds-codex-dispatch runtime-bindings "<absolute-invocation-directory>"` and
accept its JSON bindings only when they match the paths established above.

**Note:** This file is auto-generated by `$AE_REPO_DIR/.codex/build.sh`. Do not edit it directly - edit the source files in `content/sections/` (methodology) or `content/rules/` (other rules) instead.

## Activation preflight (pointer)

Run the activation preflight once at the first skill invocation (and every `/`-command), before any other operational instruction: identity resolution, opt-in/opt-out check, and profile resolution. Its full procedure is Step 1 of the loaded methodology - invoke the `dinostack` skill below and follow it before proceeding. Do not spawn or use LLM reasoning for this step; it is a direct resolver call.

## Identity confirmation (provisional handle)

When the activation preflight resolves a provisional effective identity, surface this notice at the first user-facing turn - non-blocking:

```
IDENTITY: tracking handle '<handle>' auto-derived (provisional) - confirm or correct.
Telemetry is buffered (not lost) until confirmed.
  Confirm (global/project): ds-identity confirm --scope <global|project>
  Correct (global/project): ds-identity init <handle> --force --scope <global|project>
  Show (profile): ds-identity show --scope profile --profile-dir "$AE_CODEX_CONFIG_DIR"
  Confirm (profile): ds-identity confirm --scope profile --profile-dir "$AE_CODEX_CONFIG_DIR"
  Correct (profile): ds-identity init <handle> --force --scope profile --profile-dir "$AE_CODEX_CONFIG_DIR"
```

Profile commands use the active config binding; add `--profile-dir <dir>` only when absent. The notice re-surfaces until confirmation. Full contract: `$AE_REPO_DIR/content/commands/ds-identity.md`.

## Load the methodology on trigger

Before starting any task, check if the `dinostack` skill should be loaded: code edits, debugging, testing, deployment, architecture decisions, git operations, agent orchestration, code review, refactoring, dependency management, or project setup. If any signal matches, invoke it (`$dinostack`) before proceeding - it carries the activation preflight, delegation model, risk classification, Skeptic loop, quality gates, agent definitions, and every reference doc. When in doubt, invoke it.
