Companion to executus-skills#1, which replaces the gif pack's bare encode.py with a full render harness. Two edits to agentbuiltins/agents/gifsmith/agent.yml's system prompt:
The skill-load line names the harness rather than "the bundled encode helper".
A short paragraph on what the agent is aiming for.
The second is the load-bearing one. Measuring 128 production runs showed the common failure is not a broken render — it's a technically-correct one that reads badly: the subject drawn too small to recognise, the action narrated in a caption instead of animated, long runs of pixel-identical frames. The recipe never asked for anything else, and neither did this prompt. Naming the bar ("something someone would actually laugh at and re-post, not a diagram that technically contains the requested objects") moved every sample in A/B testing against GLM-5.2, which is what the thinking tier resolves to in production.
Full findings, method and results: docs/audits/2026-07-24-gifsmith-quality.md in mort#1503.
go build ./..., go vet ./... clean; go test ./agentbuiltins/... passing.
Note the ordering — this needs an executus release plus a mort go.mod bump to reach production, while the pack change ships separately via .skillpack apply gif. The prompt tolerates either order: it points at a harness the pack may not have yet, and the pack's own SKILL.md is what actually teaches the API.

The gif pack now bundles a render harness rather than a bare encode helper, so
the system prompt names it. It also states what the agent is actually aiming
for: measurement against production runs showed the common failure is not a
broken render but a technically-correct one that reads badly — subject drawn too
small to recognise, action narrated in a caption instead of animated. Full

🔒 Security — No material issues found
No material issues found
The diff is a pure text edit to a static system-prompt YAML field. No new tools, no new access patterns, no new data flows are introduced.
The renamed harness reference ("bundled render harness" replacing "bundled encode helper") carries no security delta — it's a description of what a skill will teach the agent at runtime, not an authorization or execution boundary.
The new quality-bar paragraph ("something someone would actually laugh at…") is inert from a security standpoint: it steers output aesthetics, not tool usage or data handling.
code_exec, the only genuinely sensitive tool in scope, was already present in both the tool list and the original prompt; the new text does not broaden or change its invocation instructions.
No user-supplied data is interpolated into the system prompt, so there is no prompt-injection surface introduced by the new wording.
No URL construction, external fetch instruction, or path manipulation appears in the added text; the SSRF-protect infrastructure already in tool/ssrf_protect.go is unaffected.
🎯 Correctness — No material issues found
No material issues found
The diff is a pure system-prompt edit to a YAML agent definition. The gif skill pack it references lives in the companion executus-skills repo, not here — I verified the agentbuiltins/agents/gifsmith/ directory contains only agent.yml, and no encode.py or equivalent exists anywhere in this repo. With that scope in mind:
Recipe enumeration (lines 18–20): The new list adds staging rules as a discrete item alongside the existing code_exec workspace rules and upgrades bundled encode helper → bundled render harness. Both changes match what the companion PR (executus-skills#1) says it delivers. No factual mismatch I can identify within what's verifiable here.
Harness ownership claim (lines 21–23): "owns the scratch dir, frame numbering, the locked canvas size and the encode" — accurate description of what a render harness would own if it replaced a bare encode.py. The PR description is consistent with this.
Dropped "guarantees a Discord-playable MP4" (old line ~25): Intentional and correct — the harness now owns that guarantee internally; the agent no longer needs to carry that constraint consciously.
"everything on screen moves" (new line ~27): Absolute phrasing, but intentional. The PR documents this as the data-driven remedy for "long runs of pixel-identical frames" from 128 production runs. It's a quality directive, not a factual claim — no correctness bug.
YAML structure: The block scalar (|) formatting and indentation are clean in the checked-out file.
🧹 Code cleanliness & maintainability — No material issues found
No material issues found
Reviewed through the cleanliness & maintainability lens.
The diff makes two edits to a YAML system prompt. I read the full file (agentbuiltins/agents/gifsmith/agent.yml) to check context.
What I verified:
YAML structure is valid and the prompt renders cleanly with the new paragraph.
ALL-CAPS emphasis (DRAWN) is consistent with the pre-existing convention in this file (do NOT introduce yourself).
The old text named the harness concept twice in close succession ("the bundled encode helper" in the parenthetical, then "The skill also bundles an encode helper…" in the next sentence). The new text keeps the same two-mention pattern (parenthetical + elaborating sentence) but the two descriptions no longer drift — both now say "render harness", which is tighter.
The new quality-bar paragraph slots naturally between the skill-setup instruction and the reference-image instruction — a sensible reading order.
No dead or duplicated text introduced; no structural inconsistency with the surrounding file.
Nothing in this diff raises a maintainability concern.
⚡ Performance — No material issues found
No material issues found.
This diff is a pure system-prompt text edit — no code paths, data structures, loop bodies, or tool invocations are added or changed. The agent's resource bounds (max_iterations: 50, max_tool_calls: 80, max_runtime_seconds: 1800) are unchanged. The new quality-bar paragraph could nudge the model toward generating more animated frames (more movement) than it otherwise would, but that's bounded by the existing limits and is the intentional trade-off this PR is making, not a regression. Nothing here touches hot paths, allocation patterns, query fan-out, or any other efficiency surface.
🧯 Error handling & edge cases — No material issues found
No material issues found
The diff is a system-prompt string change in a YAML configuration file — no Go code, no error paths, no resource management, no boundary conditions, nothing subject to the error-handling & edge-cases lens. There are no ignored errors, missing defers, nil-dereference risks, or unhandled edge cases to review here.
glm-5.2:cloud (ollama-cloud) — No material issues found
Verdict: No material issues found — 5 reviewers: security, correctness, maintainability, performance, error-handling
🔒 Security — No material issues found
VERDICT: No material issues found
This PR edits only static text in a YAML system prompt (agentbuiltins/agents/gifsmith/agent.yml), changing the description of what the agent loads and adding a quality-bar paragraph. There are no code paths, no input parsing, no template interpolation, no handling of untrusted input, and no auth/authz changes. The prompt text itself is not user-controlled, so there is no prompt-injection surface introduced by this diff (the agent already consumes arbitrary user descriptions upstream; that pre-existing surface is untouched by this change).
I verified the full file (agentbuiltins/agents/gifsmith/agent.yml:1-54) to confirm the diff is text-only and that no new tool bindings, skill loads, or execution behavior are introduced beyond what already existed.
🎯 Correctness — No material issues found
Through the correctness lens, this is a pure prompt-text change to a YAML agent definition — no code, no constants, no formulas, no thresholds. The edits are prose substitutions: "encode helper" → "render harness", plus an added guidance paragraph. There is no semantic/numeric logic introduced that could be wrong.
One thing worth a quick correctness note: the new prose introduces terms ("staging rules", "render harness", "locked canvas size") that the prompt asserts the gif skill pack provides. The PR description explicitly acknowledges this depends on the companion executus-skills PR and notes the prompt "tolerates either order" — i.e., if the pack hasn't shipped the harness yet, the prompt names something that doesn't exist yet. That is a forward-compatibility concern the author already flagged, and it's outside the correctness-of-this-diff's-own-logic scope (it's a cross-pack contract, not a bug in this change). Within the diff itself, nothing is logically wrong.
Verdict: No material issues found
Verified agentbuiltins/agents/gifsmith/agent.yml in full: the change is confined to two prose edits inside system_prompt (lines 17–27). No YAML structural breakage, no list/key changes, no tool/skill-pack references altered (skill_packs: - gif unchanged at line 40; low_level_tools unchanged).
No constants, conversion factors, units, or thresholds are touched, so there's nothing to re-derive for semantic correctness.
(Outside my lens, and already acknowledged by the author): the prompt now references a "render harness" / "staging rules" / "locked canvas size" that only exist once the companion executus-skills PR ships. Author notes the prompt tolerates either ordering. Not a defect in this diff's own logic.
🧹 Code cleanliness & maintainability — No material issues found
Verdict: No material issues found.
The change is a prompt-only edit to a YAML system prompt. Through the code-cleanliness lens:
The added paragraph follows the existing structure and tone of the surrounding prompt (imperative, plain prose, no new formatting conventions introduced).
No duplicated or dead text. The removed "encode helper" wording is fully replaced; no stale references to the old "bundled encode helper" remain (verified by reading the full file — the only mentions of the harness/encode now consistently refer to "render harness").
Naming is consistent: the new "staging rules" and "render harness" terms are introduced once and used consistently; "plumbing" is a reasonable shorthand for the scratch-dir/frame-numbering/canvas/encode set just enumerated.
No cleanliness or maintainability concerns in my lane.
⚡ Performance — No material issues found
No material issues found
This PR edits only the system_prompt text in agentbuiltins/agents/gifsmith/agent.yml. There are no code paths, allocations, queries, loops, or hot paths touched — through the performance lens there is nothing to evaluate. The change adds a few lines of prompt text and rewording; any cost/latency impact (marginally longer prompt) is immaterial and not a performance regression.
🧯 Error handling & edge cases — No material issues found
No material issues found
This is a text-only edit to a system prompt in a YAML file. There is no code, no error handling, no cleanup/rollback paths, and no input-handling logic introduced by the diff — so there is nothing for the error-handling/edge-case lens to scrutinize. I verified the full file (agentbuiltins/agents/gifsmith/agent.yml) to confirm the change is purely prose and that no structural keys, tool bindings, or iteration limits that could affect failure behavior were altered.
kimi-k2.6:cloud (ollama-cloud) — No material issues found
Verdict: No material issues found — 5 reviewers: security, correctness, maintainability, performance, error-handling
🔒 Security — No material issues found
No material issues found
The diff is a purely cosmetic prompt update: it rewords the skill description ("render harness" replacing "encode helper") and adds qualitative guidance for output quality. No security surface changes. Tool permissions, execution limits, skill packs, and model tier are all untouched. There are no new injection vectors, no secrets, no auth boundary changes, and no unsafe defaults introduced.
🎯 Correctness — No material issues found
Verdict: No material issues found.
The change is purely editorial: two updates to a system-prompt YAML string, with no executable code, no constants, formulas, thresholds, or logic paths introduced or altered. Forward/backward compatibility with the skill pack is explicitly intentional per the PR description.
🧹 Code cleanliness & maintainability — No material issues found
No material issues found.
The change is a clean, focused prompt update in a single YAML file. From a code cleanliness & maintainability lens:
No dead or duplicated code — the old "bundled encode helper" paragraph is cleanly replaced by the updated "render harness" description, and the new quality-bar paragraph is additive where it belongs.
Consistent terminology — "render harness" is used consistently throughout the updated lines, matching the described architecture in the companion PR.
Readable structure — the new paragraph is concise, punchy, and thematically grouped with the rest of the system_prompt block. It doesn't bloat the file or break the YAML formatting.
Follows existing patterns — the surrounding agent YAML style (line-wrapping, indentation, pipe literal for multi-line strings) is preserved.
Nothing in my area.
⚡ Performance — No material issues found
No material issues found
This is a purely textual prompt edit in a YAML manifest (agent.yml). There are no code changes, algorithmic modifications, or runtime behavior differences that would affect performance. The added paragraph (~3 lines) does not meaningfully increase token context relative to the existing prompt, and the PR description notes it improved output quality in A/B testing. No loops, queries, allocations, or hot paths are touched.
🧯 Error handling & edge cases — No material issues found
No material issues found.
This change is a purely textual revision to a system prompt in a YAML configuration file. It introduces no code paths, no function calls, no resource acquisition or release, and no conditional logic. There are therefore no ignored errors, missing defers, nil dereferences, empty-collection risks, integer overflows, or off-by-one conditions to evaluate through the error-handling & edge-cases lens. The YAML remains well-formed (the | block scalar and indentation are correct).

Measuring 128 production runs showed the common failure is not a broken render — it's a technically-correct one that reads badly: the subject drawn too small to recognise, the action narrated in a caption instead of animated, long runs of pixel-identical frames. The recipe never asked for anything else, and neither did this prompt. Naming the bar ("something someone would actually laugh at and re-post, not a diagram that technically contains the requested objects") moved every sample in A/B testing against GLM-5.2, which is what the
thinkingtier resolves to in production.Full findings, method and results:
docs/audits/2026-07-24-gifsmith-quality.mdin mort#1503.go build ./...,go vet ./...clean;go test ./agentbuiltins/...passing.Note the ordering — this needs an executus release plus a mort
go.modbump to reach production, while the pack change ships separately via.skillpack apply gif. The prompt tolerates either order: it points at a harness the pack may not have yet, and the pack's own SKILL.md is what actually teaches the API.🤖 Generated with Claude Code

The diff is a pure text edit to a static system-prompt YAML field. No new tools, no new access patterns, no new data flows are introduced.
code_exec, the only genuinely sensitive tool in scope, was already present in both the tool list and the original prompt; the new text does not broaden or change its invocation instructions.tool/ssrf_protect.gois unaffected.🎯 Correctness — No material issues found
No material issues found
The diff is a pure system-prompt edit to a YAML agent definition. The
gifskill pack it references lives in the companion executus-skills repo, not here — I verified theagentbuiltins/agents/gifsmith/directory contains onlyagent.yml, and noencode.pyor equivalent exists anywhere in this repo. With that scope in mind:Recipe enumeration (lines 18–20): The new list adds
staging rulesas a discrete item alongside the existingcode_exec workspace rulesand upgradesbundled encode helper→bundled render harness. Both changes match what the companion PR (executus-skills#1) says it delivers. No factual mismatch I can identify within what's verifiable here.Harness ownership claim (lines 21–23): "owns the scratch dir, frame numbering, the locked canvas size and the encode" — accurate description of what a render harness would own if it replaced a bare
encode.py. The PR description is consistent with this.Dropped "guarantees a Discord-playable MP4" (old line ~25): Intentional and correct — the harness now owns that guarantee internally; the agent no longer needs to carry that constraint consciously.
"everything on screen moves" (new line ~27): Absolute phrasing, but intentional. The PR documents this as the data-driven remedy for "long runs of pixel-identical frames" from 128 production runs. It's a quality directive, not a factual claim — no correctness bug.

⚡ Performance — No material issues found
No material issues found.
This diff is a pure system-prompt text edit — no code paths, data structures, loop bodies, or tool invocations are added or changed. The agent's resource bounds (
max_iterations: 50,max_tool_calls: 80,max_runtime_seconds: 1800) are unchanged. The new quality-bar paragraph could nudge the model toward generating more animated frames (more movement) than it otherwise would, but that's bounded by the existing limits and is the intentional trade-off this PR is making, not a regression. Nothing here touches hot paths, allocation patterns, query fan-out, or any other efficiency surface.🧯 Error handling & edge cases — No material issues found
No material issues found
The diff is a system-prompt string change in a YAML configuration file — no Go code, no error paths, no resource management, no boundary conditions, nothing subject to the error-handling & edge-cases lens. There are no ignored errors, missing defers, nil-dereference risks, or unhandled edge cases to review here.

VERDICT: No material issues found
This PR edits only static text in a YAML system prompt (
agentbuiltins/agents/gifsmith/agent.yml), changing the description of what the agent loads and adding a quality-bar paragraph. There are no code paths, no input parsing, no template interpolation, no handling of untrusted input, and no auth/authz changes. The prompt text itself is not user-controlled, so there is no prompt-injection surface introduced by this diff (the agent already consumes arbitrary user descriptions upstream; that pre-existing surface is untouched by this change).I verified the full file (
agentbuiltins/agents/gifsmith/agent.yml:1-54) to confirm the diff is text-only and that no new tool bindings, skill loads, or execution behavior are introduced beyond what already existed.🎯 Correctness — No material issues found
Through the correctness lens, this is a pure prompt-text change to a YAML agent definition — no code, no constants, no formulas, no thresholds. The edits are prose substitutions: "encode helper" → "render harness", plus an added guidance paragraph. There is no semantic/numeric logic introduced that could be wrong.
One thing worth a quick correctness note: the new prose introduces terms ("staging rules", "render harness", "locked canvas size") that the prompt asserts the
gifskill pack provides. The PR description explicitly acknowledges this depends on the companion executus-skills PR and notes the prompt "tolerates either order" — i.e., if the pack hasn't shipped the harness yet, the prompt names something that doesn't exist yet. That is a forward-compatibility concern the author already flagged, and it's outside the correctness-of-this-diff's-own-logic scope (it's a cross-pack contract, not a bug in this change). Within the diff itself, nothing is logically wrong.Verdict: No material issues found
agentbuiltins/agents/gifsmith/agent.ymlin full: the change is confined to two prose edits insidesystem_prompt(lines 17–27). No YAML structural breakage, no list/key changes, no tool/skill-pack references altered (skill_packs: - gifunchanged at line 40;low_level_toolsunchanged).🧹 Code cleanliness & maintainability — No material issues found
Verdict: No material issues found.
The change is a prompt-only edit to a YAML system prompt. Through the code-cleanliness lens:
No cleanliness or maintainability concerns in my lane.
⚡ Performance — No material issues found
No material issues found
This PR edits only the
system_prompttext inagentbuiltins/agents/gifsmith/agent.yml. There are no code paths, allocations, queries, loops, or hot paths touched — through the performance lens there is nothing to evaluate. The change adds a few lines of prompt text and rewording; any cost/latency impact (marginally longer prompt) is immaterial and not a performance regression.🧯 Error handling & edge cases — No material issues found
No material issues found
This is a text-only edit to a system prompt in a YAML file. There is no code, no error handling, no cleanup/rollback paths, and no input-handling logic introduced by the diff — so there is nothing for the error-handling/edge-case lens to scrutinize. I verified the full file (
agentbuiltins/agents/gifsmith/agent.yml) to confirm the change is purely prose and that no structural keys, tool bindings, or iteration limits that could affect failure behavior were altered.kimi-k2.6:cloud (ollama-cloud) — No material issues found
Verdict: No material issues found — 5 reviewers: security, correctness, maintainability, performance, error-handling
🔒 Security — No material issues found
No material issues found
The diff is a purely cosmetic prompt update: it rewords the skill description ("render harness" replacing "encode helper") and adds qualitative guidance for output quality. No security surface changes. Tool permissions, execution limits, skill packs, and model tier are all untouched. There are no new injection vectors, no secrets, no auth boundary changes, and no unsafe defaults introduced.
🎯 Correctness — No material issues found
Verdict: No material issues found.
The change is purely editorial: two updates to a system-prompt YAML string, with no executable code, no constants, formulas, thresholds, or logic paths introduced or altered. Forward/backward compatibility with the skill pack is explicitly intentional per the PR description.
🧹 Code cleanliness & maintainability — No material issues found
No material issues found.
The change is a clean, focused prompt update in a single YAML file. From a code cleanliness & maintainability lens:
system_promptblock. It doesn't bloat the file or break the YAML formatting.Nothing in my area.
⚡ Performance — No material issues found
No material issues found
This is a purely textual prompt edit in a YAML manifest (
agent.yml). There are no code changes, algorithmic modifications, or runtime behavior differences that would affect performance. The added paragraph (~3 lines) does not meaningfully increase token context relative to the existing prompt, and the PR description notes it improved output quality in A/B testing. No loops, queries, allocations, or hot paths are touched.🧯 Error handling & edge cases — No material issues found
No material issues found.
This change is a purely textual revision to a system prompt in a YAML configuration file. It introduces no code paths, no function calls, no resource acquisition or release, and no conditional logic. There are therefore no ignored errors, missing defers, nil dereferences, empty-collection risks, integer overflows, or off-by-one conditions to evaluate through the error-handling & edge-cases lens. The YAML remains well-formed (the
