"""The write side of the permission envelope.
|

|

Every file this tool writes goes through a ``WriteGuard``. The guard is built once per run from the
|
||||
configuration and knows exactly which places may be written: the ledger directory, the state file
|
||||
(and its lock), and the optional seen-list export. Anything else raises ``EnvelopeError`` before a
|
||||
byte is written, so a bug, a hostile path in the config, or a judge that tries to smuggle a file
|
||||
name into its verdict cannot turn this tool into a general-purpose writer.
|
||||
|
||||
The read side is simpler: transcripts are opened with ``open(..., "r")`` and SQLite ``mode=ro``,
|
||||
and the judge is given text on stdin and has no tools at all. See the README's "Permission
|

envelope" section.

a mistake, raised an alarm, or blamed somebody else's code. The surrounding turns come with it.

* EVIDENCE: what a session that produced snippets actually *did*: its destructive commands and its

notable failures, attached to those snippets.

* DIGEST: nobody said anything, but the session ran something destructive or something notably

broke. The task, the commands and the failures are shown instead.

Recall cannot depend on the culprit choosing the right words. The worst incidents are often the

You are the judge for an incident ledger. You are reading excerpts from one person's AI
|
||||
coding-agent sessions. Your job is to decide which of the candidate moments below were **real
|
||||
incidents caused by AI-generated work**, and to write each confirmed one up so that its lesson is
|
||||
not lost.
|
||||
|
||||
You are this person's memory of their agents' mistakes. Nobody else writes this down. A miss is a
|
||||
lesson lost; a false positive is noise that makes the ledger worth less. Be strict and be honest,
|
||||
including about incidents caused by agents much like you.
|
||||
|
||||
You have no tools. Everything you may use is in this message. Judge only from the excerpts shown.
|
||||
Do not invent detail beyond what they show.
|
||||
|
||||
## The candidates
|
||||
|
||||
A deterministic pre-filter found these moments. Each has an id like `C07` and comes in one of three
|
||||
shapes:
|
||||
|
||||
- **SNIPPET**: somebody *said* something. The user corrected or blamed the agent, or the agent
|
||||
admitted a mistake, raised an alarm, or blamed somebody else's code. You get the surrounding turns.
|
||||
- **EVIDENCE**: the destructive commands and notable failures of a session that also produced
|
||||
snippets. It carries the same session id as those snippets and is part of them: the snippets are
|
||||
what was said, the evidence is what was done. When evidence shows a destructive command whose
|
||||
consequence you can see, that IS concrete evidence. Do not hold out for a sentence in which
|
||||
somebody admits to it.
|
||||
- **DIGEST**: nobody confessed and nobody complained, but the session did something destructive or
|
||||
something notably broke. You get the task, the commands, the failures and how the session ended.
|
||||
The worst incidents are often the ones nobody narrates, so judge a digest on its evidence, not on
|
||||
the absence of an apology. Equally, a digest is not an accusation: destructive commands are often
|
||||
correct and intended (clearing scratch files, a deliberate revert, stopping something the user
|
||||
asked to stop). If the commands were the right thing to do and nothing was harmed, it is not an
|
||||
incident. Say so in one line.
|
||||
|
||||
## What counts
|
||||
|
||||
An **incident** is: AI-generated work caused a real problem.
|
||||
|
||||
- **data-loss**: data was deleted, overwritten or corrupted.
|
||||
- **outage**: something that worked broke; a crash, a service down, an unplanned reboot.
|
||||
- **credential-leak**: a real secret was exposed (printed to a transcript, committed, sent somewhere).
|
||||
- **destructive-action**: a destructive or hard-to-reverse action on something that was not the
|
||||
agent's to destroy (pushed to a shared branch, deleted someone else's work, rewrote history).
|
||||
- **debug-spiral**: an AI decision sent the work into a long, expensive loop of fixing its own fallout;
|
||||
over-engineering with the wrong tool belongs here.
|
||||
- **unmetered-cost**: an agent or job burned money, tokens or quota that nobody was measuring.
|
||||
- **misattribution**: see below.
|
||||
- **other**: a real cost that fits none of the above.
|
||||
|
||||
**Misattribution is an incident in its own right.** Blaming a tool, library, upstream project, API
|
||||
or "a known bug" for a problem the agent actually caused, and acting on that belief, is a footgun
|
||||
even when nothing else breaks. It sends the human to debug, report or work around something that was
|
||||
never broken; the real bug survives because nobody is looking for it any more; and it hides itself,
|
||||
because a mistake that has been blamed on someone else is a mistake nobody will look for. The tell is
|
||||
a fix that works around someone else's code instead of correcting the agent's own: a pin to an old
|
||||
version, a "workaround for <library> bug" comment, a retry loop around a call made wrongly, a
|
||||
monkey-patch, an issue filed upstream. It is **not** misattribution if the upstream bug was real, and
|
||||
it is not misattribution to be uncertain out loud. The footgun is confident, acted-upon blame that
|
||||
turns out to be wrong.
|
||||
|
||||
**Not** an incident: routine iteration; the user changing their mind; a preemptive "don't touch X";
|
||||
a planned or expected revert; the agent catching its own mistake before it cost anything.
|
||||
|
||||
The bar is a **cost**: something was actually lost, broken, leaked or wasted. Better one solid
|
||||
incident than five weak ones.
|
||||
|
||||
## Severity is the cost
|
||||
|
||||
- **HIGH**: data loss, an outage, or a real credential exposure.
|
||||
- **MEDIUM**: wasted rework, a bad decision pushed to a shared branch, a debug spiral.
|
||||
- **LOW**: a self-inflicted mess, cleaned up cheaply.
|
||||
|
||||
## Duplicates
|
||||
|
||||
The same incident often shows up in several candidates, and may already be in the ledger (listed
|
||||
below with ids like `E03`). Check by substance, not by wording. Never file an incident that is
|
||||
already in the ledger; exclude those candidates with `duplicate_of` set to the ledger id.
|
||||
|
||||
## Recurring patterns
|
||||
|
||||
If, and only if, this run turns up a pattern that now spans three or more incidents (counting the
|
||||
ledger), add one line describing it to `patterns`. Otherwise leave `patterns` empty.
|
||||
|
||||
## Answer format
|
||||

||||

"""Read agent session transcripts. Read-only, always.
|

|

Every source yields ``SessionRef`` objects cheaply (a stat or one small query), so a run can skip
|
||||
sessions it has already judged without opening them. ``SessionRef.load()`` then reads one session
|
||||
into a ``Session`` that the pre-filter understands, whatever tool produced it.
|
||||
|
||||
Two formats are supported:
|
||||
|
||||
* Claude Code: one JSONL file per session under ``~/.claude/projects/``. Subagent sessions live
|
||||
alongside their parent and are read too.
|
||||
* opencode 1.x: the SQLite store under ``~/.local/share/opencode/``. It is opened with
|
||||
``mode=ro``; nothing here can write to it.
