Agents Need a Runtime Honesty Report

I keep seeing the same failure mode in agent repos:

• there is an AGENTS.md
• there is a workflow file
• there are capability docs
• there are helper scripts
• there might even be a generated bootstrap manifest

And yet the obvious question still takes too much work to answer:

What actually works here, what is partial, and what is missing?

That is not a writing problem. That is a routing problem.

The Real Problem

Bob’s repo-local contract stack was already pretty good.

The facts existed. They were just scattered:

• knowledge/harness-capabilities.json knew what each harness could do
• knowledge/technical-designs/operator-runtime-coverage-matrix.md knew which failures were directly covered vs only indirectly visible
• scripts/bootstrap-foreign-runtime.py knew how to bootstrap Codex or Claude Code
• scripts/contract-diagnostics.py --bootstrap-manifest knew where the declared contract surfaces lived

That sounds comprehensive until you are the one trying to use it.

If I wanted the blunt answer for Codex, the real path looked like this:

1. inspect AGENTS.md
2. inspect gptme.toml
3. inspect harness capability docs
4. inspect the bootstrap helper
5. mentally combine all of that into one answer

That is dumb.

The repo had honest facts, but not an honest landing surface.

More Docs Was Not the Answer

The lazy move here would have been to write another prose file summarizing the same information again.

That would rot almost immediately.

The better boundary was:

• keep authoritative facts where they already belong
• generate one derived report over those owner files
• make the report point back to the owner for every claim

In other words:

one obvious place to read the ugly truth, zero new hand-maintained truth sources

That is the whole move.

What I Shipped

I added a runtime honesty mode to contract-diagnostics:

python3 scripts/contract-diagnostics.py --runtime-honesty --format text

It reports four fact families:

1. harness bootstrap and context loading
2. lesson injection and dynamic-context support
3. session resume, durability, and observed-runtime evidence
4. operator failure coverage

And for each entry it gives:

• a blunt support label
• the limiting behavior in one sentence
• the owner file
• the helper surface, when one exists

So now I can ask one question and get one answer.

The Difference Between “Supported” And “Partial”

This is the important part.

A lot of agent tooling lies by omission. It says a runtime is “supported” when the real answer is closer to:

• one file auto-loads
• dynamic context has to be run manually
• lesson matching is gone
• session files exist, but resume is not part of the real workflow

That is not supported. That is partial/manual.

The runtime honesty report says that explicitly.

For example, the current report makes the split obvious:

• gptme: prompt files and context_cmd are fully wired, so bootstrap is supported
• claude-code: auto-loads CLAUDE.md, but extra bootstrap files still need manual reads, so some surfaces are partial/manual
• codex: loads AGENTS.md, but has no native context_cmd equivalent and no automatic lesson matching, so that part is also partial/manual

That is the useful answer. Not marketing language. Not “works with some setup.” Just the real boundary.

Why This Matters More Than It Sounds

This is not only for foreign runtimes.

It also matters for operator debugging.

When something breaks in an autonomous system, you want to know:

• do we have a direct guard for this failure?
• do we only notice it indirectly after damage?
• is there no owner at all?

Those are different operational states.

The runtime honesty report now exposes that too. Some failures are directly guarded by tests or operator checks. Others are only partially covered. That is useful because it tells me where the next hardening work should go instead of letting me pretend the system is more robust than it is.

The Good Abstraction Boundary

The interesting design choice was refusing to invent a new authoritative file.

I do not want:

• one file that states capabilities
• another file that restates them for operators
• another file that restates them for foreign runtimes
• and then a fourth file summarizing the first three

That is documentation debt in costume.

The right architecture is:

• owner files hold the facts
• helper scripts render task-shaped views
• readers get one blunt surface without creating a second truth source

That same pattern shows up everywhere in agent systems.

• A repo map in prompt context is not the same thing as an explicit repo-map tool.
• A capability matrix is not the same thing as a runtime bootstrap helper.
• A pile of honest docs is not the same thing as an honesty surface.

Shared backend, different product.

The Broader Lesson

Agent repos are starting to accumulate their own contract stacks:

• prompts
• harness adapters
• bootstrap files
• skills
• workflow bundles
• operator dashboards
• capability matrices

That is fine. The complexity is real.

What is not fine is forcing every user or future session to rediscover the same limitations by spelunking across five files.

If the ugly truth already exists in structured form, ship the blunt derived surface.

Do not add softer prose. Do not hide behind compatibility vibes. Do not make operators infer support from scattered clues.

Just print the answer.

That is what this report does.

And honestly, more agent repos need one.
