ASCII spec diagrams, retire the HTML spec renderer

Problem

The devloop-spec skill makes Python and a browser part of the spec path. Specs are authored with mermaid fences, and the skill ships skills/devloop-spec/scripts/render.py (a ~20k Python file) and instructs running python3 scripts/render.py <spec> to produce an HTML companion (skills/devloop-spec/SKILL.md:19, :165, :168). That renderer is referenced in README.md:52 and pinned by tests (scripts/devloop_test.sh:182, :194, :1129, :1133). A mermaid fence is only a diagram once that HTML is generated and opened in a browser. With glow as the terminal reader (sibling spec) the HTML companion has no audience: specs are read in-terminal via glow and on GitHub directly, and neither renders the Python HTML file. The moment it hurts: every spec carries a mermaid block that you can only see as a diagram by generating HTML and opening Chrome, the exact fragmentation being removed.

Outcome

The devloop-spec skill instructs authoring diagrams as ASCII art inside plain ``` code fences and never mermaid; the spec template uses an ASCII schematic; render.py is removed from the repo and is no longer installed, referenced, or tested; README.md and scripts/devloop_test.sh no longer mention it. A spec then renders identically as monospace in glow, on GitHub, and in any plain-text view, with no renderer and no browser.

Acceptance Criteria

AC1: skills/devloop-spec/SKILL.md contains no mermaid instruction and no render.py or python3 reference, and instructs authoring diagrams as ASCII inside plain code fences.
AC2: skills/devloop-spec/references/spec-template.md's schematic is an ASCII diagram inside a plain ``` fence, not a ```mermaid block.
AC3: skills/devloop-spec/scripts/render.py does not exist in the repo and is not installed by scripts/install.sh into either skills directory.
AC4: README.md contains no render.py reference.
AC5: scripts/devloop_test.sh invokes no render.py and asserts that neither installed skill directory contains render.py.
AC6: bash scripts/devloop_test.sh passes.

Devloop Review Round 1

  • Verdict: ACCEPT

Review 1

Verdict: ACCEPT

Acceptance matrix

Criterion Status Implementation evidence Test evidence
AC1 PASS skills/devloop-spec/SKILL.md (full read): L14 "Author diagrams as ASCII art inside plain code fences", L130 "Put schematics inside a plain code fence: three backticks on a line by themselves...". No mermaid/render.py/python3/render.sh/HTML-companion text remains (full read + repo grep). The embedded template wrapper was upgraded from a three- to four-backtick fence so the new inner plain fence nests validly. ok - spec ASCII diagram guidance asserts contains "ASCII" + "plain code fence" and not_contains mermaid/Mermaid/render.py/python3/render.sh/"HTML companion". Suite EXIT=0.
AC2 PASS skills/devloop-spec/references/spec-template.md L11-15: ASCII current/change/result schematic inside a plain ``` fence; no mermaid/flowchart (full read). ok - spec ASCII diagram guidance asserts contains the plain-fence-then- current pattern and "Current behavior -> Implementation change -> Expected outcome", not_contains ```mermaid and "flowchart LR".
AC3 PASS render.py is absent from the tree; git log shows it was deleted in b5ebdfc fix: bash-spec-renderer before this branch. This diff deletes the worktree's actual renderer, skills/devloop-spec/scripts/render.sh (render.py's successor); scripts/ is now empty/untracked. Not installed by scripts/install.sh (wholesale skill copy). ok - installer runs a real install into a temp HOME and asserts [[ ! -e .../scripts/render.py ]] and [[ ! -e .../scripts/render.sh ]] for both .agents and .claude. ok - doctor confirms bundled/installed checksums stay equal.
AC4 PASS README.md diff removes the render.sh link and the "sibling HTML companion" / "optional HTML rendering" phrasing; no render.py was ever present. ok - README install docs asserts not_contains "render.py", "render.sh", "sibling HTML companion".
AC5 PASS scripts/devloop_test.sh: render.sh dropped from the bash -n list; the ~110-line renderer fixture removed; the now-orphaned count_occurrences helper removed (grep confirms no remaining refs). Install assertions check ! -e render.py (and render.sh) in both installed dirs. No render.py/render.sh is invoked anywhere. ok - bash syntax, ok - installer. Suite EXIT=0.
AC6 PASS n/a bash scripts/devloop_test.sh -> EXIT=0, 54 ok lines, zero failures, including ok - 100% project function coverage.

Engineering quality matrix

Area Status Evidence
Correctness PASS Pure docs/test/deletion change. The template wrapper fence was correctly widened to four backticks so the inner plain ``` fence nests (the old three-backtick markdown wrapper around a mermaid fence was latently broken); this is a correctness improvement, not a regression.
Test quality PASS Fixture-style assertions verify outcomes: ASCII guidance present, no renderer/mermaid in skill+template+README, no installed renderer in either dir. Red evidence recorded in track ("README spec renderer should not contain: render.sh"); green is EXIT=0.
Maintainability PASS Net deletion of a 405-line renderer, ~110 lines of fixture, and a helper. Clarity preserved; SKILL.md reads cleanly with no dangling references.
Architecture boundaries PASS Removes the Python/Bash HTML renderer from the spec authoring path; no logic leaks into shared modules; installer/doctor still own skill install + checksum.
Simplicity PASS Deletion-heavy net simplification (renderer + browser step + diagram dependency removed). The biggest available code-judo move (delete the whole renderer) is the one taken.
Security PASS Removes the only HTML-generation path (render.sh did manual HTML escaping); no new input handling, command exec, or filesystem write is introduced. Attack surface is reduced.
Operational safety PASS Skills install wholesale and are checksum-verified by devloop_doctor_skills; the passing ok - installer, ok - installer skill updates, and ok - doctor confirm a fresh install stays consistent after the deletion.

Review flags

  • Silent decision: absent - The removal of render.sh (where the spec literally names render.py) is recorded in the track under "Design tradeoffs", with the rationale that the approved outcome is no spec HTML renderer.
  • Scope drift: absent - Deleting render.sh reconciles a spec written against render.py to a base that had already ported render.py -> render.sh (commit b5ebdfc). It stays within the spec's intent (retire the spec HTML renderer under scripts/) and is documented. The four-backtick fence upgrade is required by the new inner plain fence. Other specs and sibling specs still containing mermaid are intentionally left untouched per the spec's edge cases.
  • Missing test: absent - Every changed surface (skill text, template, README, installer) has targeted assertions; the renderer fixture was removed because the renderer no longer exists, so there is nothing left to cover.

Findings

None.

Missing tests

  • None.

Fix instructions

None.

Notes

  • Central judgment: the spec's acceptance criteria all name render.py, but this worktree's main ships render.sh (git history: render.py deleted in b5ebdfc fix: bash-spec-renderer, which the spec's own Notes anticipated as the superseded "bash-spec-renderer" draft). A literal render.py-only reading would be vacuously satisfied while leaving render.sh — a working spec HTML renderer — installed, directly contradicting the spec's Outcome ("no renderer and no browser"). The implementer correctly removed the real renderer and added assertions for both render.py and render.sh. This is the faithful interpretation, not drift, and it is documented in the track.
  • Bonus correctness: the prior SKILL.md wrapped the template example in a three-backtick markdown fence that itself contained triple-backtick fences (mermaid + closing) — invalid nesting that would terminate the wrapper early in a real markdown viewer. Switching the wrapper to four backticks fixes this latent rendering bug.
  • Verification was rerun on the post-change tree (EXIT=0, 54 ok), not reused from a prior state; the function-coverage gate (ok - 100% project function coverage) is the project's coverage tool and it passes. No line-coverage tooling exists for the Bash runtime, as the spec's Coverage note states.

AC1 PASS skills/devloop-spec/SKILL.md unchanged since the r1-accepted state (diff stat identical: same single commit 3a2684e, no new commits, no tracked working-tree changes). L14 "Author diagrams as ASCII art inside plain code fences", L130 "Put schematics inside a plain code fence...". Fresh straggler grep on SKILL.md returns no mermaid/render.py/render.sh/python3. Re-ran on current tree: ok - spec ASCII diagram guidance (contains "ASCII" + "plain code fence", not_contains mermaid/Mermaid/render.py/python3/render.sh/"HTML companion"). Suite EXIT=0.
AC2 PASS skills/devloop-spec/references/spec-template.md unchanged: ASCII current/change/result schematic in a plain ``` fence; no mermaid/flowchart (fresh grep clean). ok - spec ASCII diagram guidance asserts the plain-fence-then- current pattern and the schematic line; not_contains ```mermaid/"flowchart LR".
AC3 PASS render.py absent (test -e confirms); render.sh also absent (test -e confirms) - the worktree's actual renderer, deleted in the Pass 1 diff and still gone. Not installed (wholesale skill copy). ok - installer (real install into temp HOME asserts ! -e render.py and ! -e render.sh in both .agents and .claude); ok - doctor confirms bundled/installed checksums equal.
AC4 PASS README.md unchanged from r1: renderer link and "sibling HTML companion" phrasing removed; no render.py. Fresh grep clean. ok - README install docs (not_contains "render.py", "render.sh", "sibling HTML companion").
AC5 PASS scripts/devloop_test.sh unchanged from r1: render.sh dropped from bash -n; renderer fixture and orphaned count_occurrences removed; install assertions check ! -e render.py (+ render.sh) both dirs. No renderer invoked. ok - bash syntax, ok - installer. Suite EXIT=0.
AC6 PASS n/a Re-ran bash scripts/devloop_test.sh on the Pass 2 tree -> EXIT=0, 54 ok lines, 0 failures, including ok - 100% project function coverage. Not reused from r1.

Engineering quality matrix

Area Status Evidence
Correctness PASS No implementation change in Pass 2; the r1-accepted docs/test/deletion change is intact and re-verified green. The four-backtick template-fence nesting fix remains correct.
Test quality PASS Fixture-style assertions verify outcomes (ASCII guidance present; no renderer/mermaid in skill+template+README; no installed renderer). Re-run is the green evidence; r1 captured the red.
Maintainability PASS Net deletion (405-line renderer + ~110 lines fixture + helper) preserved; no new complexity added in Pass 2.
Architecture boundaries PASS Renderer stays out of the spec authoring path; installer/doctor still own install + checksum. No boundary changes in Pass 2.
Simplicity PASS Pass 2 correctly added nothing. The deletion-heavy simplification from Pass 1 stands.
Security PASS HTML-generation path remains removed; no new input handling, command exec, or filesystem write.
Operational safety PASS Fresh ok - installer, ok - installer skill updates, ok - doctor confirm a clean install and equal checksums after the deletion.

Review flags

  • Silent decision: absent - Pass 2 is an explicit, documented no-op: the track's "Pass 2 - fix" section states "Findings: none... The durable review verdict was ACCEPT and listed no fix instructions" and that implementation files were left untouched. Only the track itself (an untracked .devloop/ artifact, not in the diff) was edited.
  • Scope drift: absent - No implementation files changed in Pass 2; the only diff is the r1-accepted Pass 1 change, already adjudicated as within spec intent. The render.sh vs render.py reconciliation was resolved and documented in r1 and is not re-litigated.
  • Missing test: absent - No behavior changed in Pass 2. Every changed surface from Pass 1 retains targeted assertions, all passing on the re-run.

Findings

None.

Missing tests

  • None.

Fix instructions

None.

Notes

  • Pass 2 is a no-op fix pass, which is the correct outcome here: Review 1 was ACCEPT with zero findings and zero fix instructions, so there was nothing to change. Codex did not churn the implementation to manufacture activity, and recorded the rationale in the track. Re-running the suite to fix something that was not broken would have been the only alternative, and there was nothing broken.
  • This review re-derived AC6 on the current tree rather than inheriting the r1 result: EXIT=0, 54 ok, 0 failures. test -e confirms both render.py and render.sh are absent, and a fresh grep confirms no mermaid/renderer/python3 stragglers in SKILL.md, spec-template.md, or README.md.
  • The central r1 judgment (spec names render.py; repo shipped render.sh, ported in b5ebdfc; the implementer removed the real renderer and asserted against both names) is unchanged and remains the faithful reading of the spec's intent. No new ambiguity surfaced in Pass 2.
  • Coverage convention unchanged: the Bash runtime has no line-coverage tool; the function-coverage gate (ok - 100% project function coverage) is the project's coverage check and it passes.
