| description | Uploads text evidence to the GitHub `pr-assets` release, updates the PR description, posts a comment on the originating Linear Issue with code blocks, and transitions the Issue from the configured `claimed` label to the configured `review` label. Reusable by any skill that captures evidence and generates evidence/comment.txt + evidence/code-blocks.md. Linear counterpart of lisa:jira-evidence and lisa:github-evidence. |

Linear Evidence: $ARGUMENTS
Post verification evidence to a Linear Issue and transition it from the configured claimed build label to the configured review build label. This skill is the destination of the lisa:tracker-evidence shim when tracker = "linear".
$ARGUMENTS is the Linear Issue identifier (e.g. ENG-123) and the path to the evidence directory. Caller passes both: <IDENTIFIER> <evidence-dir>.
Workflow resolution
The claimed and review build labels are read from .lisa.config.json linear.labels.build.*, falling back to the defaults documented in the config-resolution rule (status:in-progress and status:code-review).
read_role() {
local role="$1" default="$2"
local local_v global_v
local_v=$(jq -r ".linear.labels.build.${role} // empty" .lisa.config.local.json 2>/dev/null)
global_v=$(jq -r ".linear.labels.build.${role} // empty" .lisa.config.json 2>/dev/null)
echo "${local_v:-${global_v:-$default}}"
}
CLAIMED=$(read_role claimed "status:in-progress")
REVIEW=$(read_role review "status:code-review")
Configuration
Reads linear.workspace, linear.teamKey, and linear.labels.build.* from .lisa.config.json (with .local override).
Inputs (in <evidence-dir>)
The caller must produce:
evidence/comment.txt — the human-readable comment body posted on the Linear Issue.evidence/code-blocks.md — fenced code blocks (test outputs, command output, log excerpts) appended to the comment.evidence/files/ (optional) — any text files that should be uploaded to the GitHub pr-assets release for permalink-style references.
If any of these are missing, stop and report.
Phase 1 — Resolve Linear Issue
- Parse the identifier from
$ARGUMENTS.
- Fetch via
mcp__linear-server__get_issue to confirm it exists and capture its current state, label set, and Project membership.
Phase 2 — Upload Evidence Files (optional)
If evidence/files/ is non-empty, upload each text file to the GitHub pr-assets release on the current repo via gh release upload. The release is the permalink store — keeps the Linear comment lightweight while preserving large outputs.
For each uploaded file, capture the public release URL.
Phase 3 — Update PR Description
If a PR is open on the current branch (gh pr view --json url,number,body 2>/dev/null), append an "Evidence" section to its description with:
- The Linear identifier and URL (constructed as
https://linear.app/<workspace>/issue/<IDENTIFIER>).
- Links to any uploaded evidence files.
- A short summary line (first 2 lines of
evidence/comment.txt).
If no PR is open, skip this phase.
Phase 4 — Post Linear Comment
Call mcp__linear-server__save_comment({issueId: <id>, body: <body>}) where <body> is:
[<comment.txt contents verbatim>]
<details>
<summary>Evidence</summary>
[<code-blocks.md contents verbatim>]
</details>
[<bullet list of uploaded evidence file URLs, if any>]
Linear comments support markdown including <details> collapsibles, fenced code, and links — preserve the formatting.
Phase 5 — Transition Status
Update labels via mcp__linear-server__save_issue to remove $CLAIMED and add $REVIEW. Resolve label IDs first via mcp__linear-server__list_issue_labels (create the label via create_issue_label if it doesn't exist on the team).
The native Linear state field is also updated to the team's "In Review" state if one exists — but the label remains the source of truth for cross-team consistency.
Phase 6 — Report
Return:
- Linear Issue URL with new label state
- PR URL (if updated)
- List of uploaded evidence file URLs
Rules
- Never modify the Issue description as part of evidence posting — comments only. Description edits go through
lisa:linear-write-issue.
- Never skip the label transition. The build queue is keyed off the configured
linear.labels.build.* labels; an item that ships without transitioning is invisible to monitoring.
- If
mcp__linear-server__save_comment fails, retry once. If it fails again, surface the error — don't pretend the comment was posted.
- Do not delete prior comments. The history is the audit trail.
