Investigate CLI Injection at Session Start · Entire

Is the Entire CLI injecting anything in the start of this session and if not, why? investigate.

Evidence:

• Current session: 019edc3a-aed0-7e9f-977d-e77ce53ecc1f, agent type Pi.

• Entire hooks did fire (session-start, turn-start) per .entire/logs/entire.log.

• Session state shows Entire made the once-per-session decision:

1

"context_injection_decided": true

• But the Pi transcript has no entire-context, inject_context, or the expected injected text:

A trail ties together the context for a branch...

Why not:

1. Entire does not inject on SessionStart for Pi.

   Pi injection is wired to TurnStart / before_agent_start, not session creation.

2. The trail-context gate is false for this clone.

   emitContextInjection() only emits the payload if trailsEnabledForRepo(ctx) is true. That reads .git/entire/preferences.json, and this file has no trails_enabled value, so the function returns false. The code intentionally marks context_injection_decided before that check, so it fails closed and won’t retry/spam later.

3. Also, the installed Pi extension is stale.

   .pi/extensions/entire/index.ts currently ignores hook stdout. The source template now parses {"inject_context": ...} and returns a hidden entire-context message, but the installed extension does not. So even if Entire emitted injection stdout, this installed extension would not apply it until refreshed.

Summary:

Entire tracked the session, but did not inject model context into this run. Refreshing the Pi hook extension (entire configure --agent pi / re-enable) and having trails_enabled cached true would be required for that injection path to work.

Additional Actions

• Checked out latest main: 92154228dc32
• Fast-forwarded from origin/main
• Rebuilt/installed entire into ~/.local/bin
• Refreshed the Pi extension so it now parses inject_context
• Cached trails_enabled: true
• Reset this session’s failed context_injection_decided flag

Note: working tree now has one generated config change:

M .pi/extensions/entire/index.ts

You may need to start a new Pi session for the updated extension file to be loaded.

Refresh Requirements

No, not every agent.
You only need to refresh agents whose repo-local generated integration code must learn how to consume the injection.

• Pi: yes, needed refresh. Its .pi/extensions/entire/index.ts had stale code that ignored hook stdout.
• OpenCode: likely same class — generated plugin may need refresh if installed before injection support.
• Claude Code / Codex / Gemini: usually no refresh needed if hooks are already installed. Their hooks call the entire binary; updating the binary is enough because injection is emitted by entire hooks ....
• Agents without ContextInjector support: won’t get this model-context injection regardless.

Also: injection is once per session and gated by trails_enabled. Future sessions should work now. Existing sessions that already recorded context_injection_decided: true won’t retry unless that flag is cleared.

The text you pasted:

A trail ties together the context for a branch...

is exactly the injection payload, so it looks like the refreshed Pi path is now working.
