+# Triage Priorities for Dart Analyzer
+
+This document describes the relative priorities for bugs filed under the
+`area-analyzer` tag in GitHub as in
+[this search](https://github.com/dart-lang/sdk/issues?q=is%3Aopen+is%3Aissue+label%3Aarea-analyzer).
+While there are always exceptions to any rule, in general try to align our
+priorities with these definitions.
+
+To triage bugs, search for `area-analyzer`
+[bugs that are not currently triaged](https://github.com/dart-lang/sdk/issues?q=is%3Aopen+is%3Aissue+label%3Aarea-analyzer+-label%3AP0+-label%3AP1+-label%3AP2+-label%3AP3+-label%3AP4)
+and for each bug, mark priority based on how closely it matches with the below
+constraints.
+
+## Analyzer triage priorities
+
+Descriptions here use [terms and definitions](#terms-and-definitions) from the
+end of this document. If your bug doesn't precisely match one of these,
+consider how impactful it is compared to examples given here and pick a priority
+reflecting that.
+
+### P0
+
+* Incorrect analysis errors or warnings, widespread
+* Uncaught exceptions resulting in tool crashes, widespread and no workaround
+* Incorrect resolution of symbols or libraries, widespread and no workaround
+* Incorrect data from analyzer API, widespread and with no workaround
+* Automation resulting in corrupted code from clean inputs, widespread
+* Performance regression, large and widespread
+* Any problem urgently blocking critical milestones for key users or Dart rolls
+ into Flutter/Google3
+* Security or privacy problem, widespread
+
+### P1
+
+* Incorrect analysis errors or warnings, on edge cases but no workarounds
+* Incorrect analysis infos, widespread
+* Incorrect resolution of symbols or libraries, edge cases, or widespread but
+ with workaround
+* Incorrect data from analyzer API, widespread but with workaround
+* Uncaught exceptions resulting in tool crashes, widespread but with workaround
+* Automation resulting in corrupted code from clean inputs, edge cases or with
+ an easy workaround
+* Automation resulting in incorrect code, widespread
+* Performance regression, large or widespread (but not both), or impacting key
+ users
+* An enhancement required for critical milestones for key users, or that has
+ significant evidence gathered indicating a positive impact if implemented
+* Any problem that, while it doesn't currently block, will block rolls into
+ Flutter/Google3 if not resolved within ~2 weeks
+* Security or privacy problem, in edge cases or with very simple workarounds
+
+### P2
+
+* Incorrect analysis errors or warnings, on edge cases with simple workaround
+* Incorrect analysis infos, on edge cases
+* Incorrect resolution of symbols or libraries, edge cases only with workarounds
+* Incorrect data from analyzer API, edge cases without workaround
+* Automation resulting in incorrect code, edge cases
+* Uncaught exceptions resulting in tool crashes, edge cases
+* Performance regression, large, impacting edge cases, without good workarounds
+* Security or privacy problem, theoretical & non-exploitable
+* An enhancement that the team agrees is a good idea but without strong evidence
+ indicating positive impact
+
+### P3
+
+* Uncaught exceptions caught by a fuzzer, but believed to be theoretical
+ situations only
+* Incorrect analysis errors or warnings, theoretical
+* Incorrect analysis infos, on edge cases with workaround
+* Incorrect resolution of symbols or libraries, theoretical
+* Incorrect data from analyzer API, edge case with workaround available
+* Performance regression impacting edge cases with workaround or without
+ workaround if small
+* Automation resulting in incorrect code, theoretical or edge cases with easy
+ workaround
+* An enhancement that someone on the team thinks might be good but it isn't
+ (yet?) generally agreed by those working in the area that it is good
+
+### P4
+
+* Incorrect analysis infos, theoretical
+* Incorrect data from analyzer API, theoretical
+* Theoretical performance problems
+* An enhancement that may have some evidence that it isn't a good idea to
+ implement but it isn't clear enough to close
+
+## Terms and definitions
+
+### Terms describing impact
+
+* "edge cases" - Impacting only small parts of the ecosystem. For example,
+ one package, or one key user with a workaround. Note this is an edge case
+ from the perspective of the ecosystem vs. language definition. If it isn't
+ happening much in the wild or (if there isn't evidence either way) if it
+ isn't believed to be super likely in the wild, it is an edge case.
+* "theoretical" - Something that we think is unlikely to happen in the wild
+ and there's no evidence for it happening in the wild.
+* "widespread" - Impact endemic throughout the ecosystem, or at least far
+ enough that this is impacting multiple key users.
+
+### Other terms
+
+* "automation" - Anything that changes the user's code automatically.
+ Autocompletion, quick fixing, NNBD migration, etc.
+* "corrupted code" - Modification of source code in such a way that it is
+ more than just a bit wrong or having some symbols that don't exist, but is
+ not valid Dart and would be painful to manually correct.
+* "incorrect code" - Modification of code in a way that is known to be wrong,
+ but would be trivial to figure out how to fix for the human using the tool.
+* "key users" - Flutter, Pub, Fuchsia, Dart, Google3, 1P
+* "tool" - Analysis Server, dartanalyzer, migration tool, analyzer-as-library
